Read all about it...

There are a lot of things battling it out for space on the national news agenda each day – both domestically and internationally. With recent headlines focused on public sector strikes, the earthquakes in Turkey/Syria and the on-going conflict in Ukraine there is often less space for other stories to break through.

It was, therefore, interesting to see that a House of Lords report into Heat Pumps gained national attention in late February – albeit for a day or so. The report drew attention to the limited uptake of the Boiler Upgrade Scheme (the government’s incentive programme to encourage the uptake of Heat Pumps) and suggested areas for improvement. (You can read more on page 6.)

While the story will have been of interest to many engaged with the move towards a lower-carbon economy, it is the fact it pushed through to the national headlines that speaks volumes. Although it is an issue which has been bubbling away within the sector for a while, how we decarbonise heat in both domestic and commercial buildings is gradually gaining more visability across the country.

At the same time the House of Lords report was being covered, the all-party Parliamentary Renewable and Sustainable Energy Group (PRASEG) was hosting a launch event for a new report from the Sustainable Energy Association (SEA). This report called for a ‘technologically agnostic approach’ to the decarbonisation of heat in buildings, arguing that a range of tailored solutions that deliver the best outcomes should be used. (You can read more on page 8.)

Of course, talking about important issues is one thing, delivering solutions is often quite another. It is heating engineers that are being called upon to deliver low-carbon technologies and find ways to integrate them into the diverse range of homes and buildings across the country.

It is, therefore, reassuring to hear about the moves within the industry that are underway to provide assistance and training to installers on low carbon solutions. In this issue we hear how an installer in Wales took advantage of training and assistance from Grant UK to deliver low-carbon heating at a barn conversion in Brecon. You can read more on page 26.

With a rising number of national news stories about the challenge of decarbonising heating, more people are likely to become aware of the issues. Competent, well-informed and trusted heating engineers will be well-placed to provide the advice and solutions that are increasingly required.

News HOUSE OF LORDS COMMENT ON BOILER UPGRADE SCHEME The House of Lords Environment and Climate Change Committee has concluded that the Boiler Upgrade Scheme (BUS), launched in May 2022 to encourage the take-up of Heat Pumps, is failing to deliver.

The committee has warned that if the current take-up rate continues, only 50% of the scheme’s budget will be used to help households switch to low-carbon heating systems. It also said that public awareness of low carbon heating systems is low and that the scheme has not received enough promotion.

It has called on the Government to provide greater clarity to both industry and consumers on feasible options for low-carbon home heating. It has also called for a consistent policy framework, public communications, and householder advice.

Baroness Parminter, Chair of the Environment and Climate Change Committee, said: “The transition to low-carbon heat is fundamental in the path to net zero, given that 17% of the UK’s greenhouse gas emissions come from our homes.

“The Government must quickly address the barriers we have identified to a successful take-up of the Boiler Upgrade Scheme in order to help grow the take up of low-carbon heating systems. It is vital they do so if we are going to meet our Net Zero ambitions.”

MCS REPORTS RISE IN RENEWABLES BEING INSTALLED The latest data from MCS (Microgeneration Certification Scheme), the standards organisation for home grown renewable energy and heating technology across the UK, shows record numbers of renewable installations in 2022 with a 65% increase compared to installations recorded in 2021.

In 2022, a total of 163,341 MCS certified installations were registered, over 80% of which were electricity generating technologies – mainly solar PV. This marks the highest annual deployment since 2015, when just over 200,000 installations were registered. Data shows that heat pumps have seen a significant rise in 2022 with more than 30,000 installations registered between air source and ground/water source technologies. March 2022 saw the largest spike in heat pump installations of any month in scheme history, aligning with the closure of the Domestic Renewable Heat Incentive scheme. Heat pumps are the second most popular technology type behind solar PV and accounted for 19% of total installations last year.

780 new contractors became MCS certified in 2022 which is more than double the net increase from 2020 to 2021. This makes 2022 the highest annual increase of certified contractors in over a decade. Ian Rippin, CEO of MCS, said: “We're pleased to report our second strongest year since 2015, illustrating the sector’s upward trajectory.

We had an incredibly busy 2022 and the data confirms the progress we’ve made. The future of small-scale renewable installations is becoming increasingly important, and we continue to play a crucial role in the decarbonisation of the UK's homes.”

HIGHER PRICES DRIVE VALUE OF SALES

6 APRIL 2023 PROFESSIONAL HEATING & PLUMBING INSTALLER

The value of sales through specialist plumbing and heating merchants rose in the final quarter of 2022, according to figures released by the Builders Merchants Federation (BMF) in its latest Plumbing and Heating Merchants Index (PHMI).

This was, it says, largely driven by higher prices rather than increased volumes.

Despite their being five fewer trading days in the final quarter of the year, in value terms absolute sales in Q4 2022 were +6.9% higher than in the third quarter of the year. Volume sales were lower at -2.6%, but prices increased by +9.7%.

A review of the year shows sales from January to December 2022 rose by +8.2% over the previous year. Once again this was driven by price, up by +9.3% with volume sales -1.0% lower. With three less trading days in 2022, like-for-like sales were up by +9.5%.

WORCESTER BOSCH LAUNCHES HVO CONVERSION KITS Worcester Bosch has announced it will be launching HVO Conversion Kits for its oil boiler portfolio.

The HVO (Hydrogenated Vegetable Oil) Conversion Kits will be made available for general sale later this year and will be suitable for the manufacturer’s Heatslave and Danesmoor oil-fired boiler ranges. Oil users that purchase a HVO Conversion Kit will be able to reduce the carbon output of their existing heating system without the need of moving to an alternative technology.

Martyn Bridges, Director of Technical Services of Worcester Bosch, said: “At Worcester, we believe the road to net zero requires a technology-agnostic approach, to ensure all homeowners have options when it comes to reducing their carbon output. This is why we continue to develop, introduce and strengthen new and existing technologies that can help reduce the carbon intensity of our products.”

PLUMBERS’ WEEKLY EARNINGS RISE Self-employed plumbers earned record weekly earnings last year, according to Hudson Contract, a payroll provider in the UK construction industry. Their average pay during 2022 was £1,068 per week, which was 8.5% higher than 2021, it said.

The highest-earning month for plumbing subcontractors was March 2022.

January 2022 was the lowest. Managing Director Ian Anfield said: “Our figures show the increasingly attractive earnings on offer for people who are prepared to put in the time and effort to learn the skills needed to succeed in the plumbing trade.”

ALTECNIC RELEASES ‘SEALED SYSTEM’ ISSUE OF IDRONICS UK The new issue of Idronics UK aims to enhance industry knowledge on sealed systems and their components, specifically how each component works to make the system as efficient as possible and troubleshooting any potential issues.

CUSTOM HEAT LAUNCHES ELECTRIC OFFER A Midlands-based heating and plumbing business, Custom Heat, is extending its services to comprise electrical installations and support, launching a sister brand – Custom Electric.

Managing Director, Lincoln Smith, commented: “The growth of Custom Heat in recent years has exceeded my expectations, but it is evident that we tick all the boxes for people, so with that solid foundation, we thought why not offer that same experience in another important service sector with Custom Electric. People can book easily online, they can get same day or next day appointments, they get all the expert advice they need and the professionals visiting their home or business are polite, tidy and do the job right first time.

“There has always been an element of electrical work within heating services but it’s becoming more prevalent with renewable heating systems. The Custom Group can now coordinate and undertake any complex job as well as take care of smaller electrical jobs, such as changing fittings, sockets and switches.”

The Sustainable Energy Association (SEA) and Partners’ latest report details the benefits of a technology-agnostic approach to decarbonising buildings; tailoring solutions to achieve the best outcomes.

The SEA has long advocated for a ‘fabric-first’, holistic approach to decarbonising buildings. This report brings together expertise from across the industry to explain why incorporating a diverse range of low-carbon technologies into heat and buildings policy is crucial to delivering Net Zero.

Bim Afolami, MP, commented: “The Sustainable Energy Association’s latest report emphasises the need for flexible, low carbon and smart technologies to be at the centre of home heat solutions. Our built environment is historically complex and diverse, so a range of interventions are needed across the domestic heat market. This report sets out the need for a variety of data-driven, market-led and bottom-up approaches to decarbonise construction, diversify supply, promote cost-efficiency and support delivery. The contributors to this report have done the legwork to demonstrate how this can be achieved in line with our mission to reach Net Zero by 2050.”

Jade Lewis, Chief Executive of the SEA, commented: “The SEA is steadfast in its commitments to deliver living and working space fit for future generations. To help us realise this vision, government policy for heat and buildings needs to be long term and joined-up, taking a fabric-first, holistic and technology-agnostic approach.

This report lays the foundations as to why these policies should take into consideration a wider range of technologies, so that we can provide homes and buildings with the best solutions for Net Zero.”

NEW DATA REVEALS HALF OF CONSTRUCTION WORKERS FEEL LONELY AT WORK New data has revealed that almost half (47%) of construction workers in the UK feel lonely in the workplace.

The findings, conducted by NESCAFÉ, are part of the ‘Make Chat Work’ campaign which aims to help businesses create a culture that nurtures their employees’ wellbeing through encouraging interactions, connections and engagement between workers.

Further insights from the research reveals that eight out of ten (79%) of construction workers agree that having opportunities to talk to colleagues around coffee breaks would make them feel less lonely. In addition, nearly all (99%) of respondents said that getting together for a coffee break is important for team morale and 94% look forward to a coffee break with colleagues.

Nadia Roberts, Brand Manager at NESCAFÉ at Nestlé Professional, said: “Our research shows that coffee breaks at work aren’t just a ‘nice to have’ but are an important part of the day for employees – particularly for those that are experiencing feelings of loneliness. Breaks give workers time that’s been specifically carved out to connect, talk and engage with each other and an opportunity to take time out and switch off from the day-to-day pressures – important for workers in any business, but particularly a sector like construction, and the related trades such as plumbers, carpenters and electricians.”

Brian Berry, Chief Executive of the Federation of Master Builders (FMB) said: “Mental health is a top priority for the FMB so our partnership with NESCAFÉ is another great way to highlight workplace wellbeing. Builders face many pressures in their day-to-day lives and it’s great that many FMB members share their own mental health challenges to help others.”

NEWS REPORT

BOILER UPGRADE SCHEME – A COMMENT

On 22nd February, the House of Lords Environment and Climate Change Committee concluded its inquiry into the Boiler Upgrade Scheme (BUS) with resulting headlines outlining the scheme’s failure to deliver. Mark Wilkins, Technologies and Training Director at Vaillant comments...

‘‘T

he conclusion of the Environmental and Climate Change Committees’ inquiry into the Boiler Upgrade Scheme [has been] announced in a letter to Lord Callanan, Under Secretary of State at the Department for Energy Security and Net Zero. At Vaillant we welcome this inquiry which reviews the uptake and mechanics of the scheme itself, the public awareness and support for transitioning to low-carbon heating systems, and the policy barriers which are underpinning the lack of market confidence.

“BUS is just one piece of the puzzle to support the increased uptake of heat pumps and to help decarbonise the UK’s housing stock. We continue to await the publication of the Green Finance Strategy, outlining how the UK’s financial services industry will deliver on ambitions for energy security, climate, and environmental objectives. We believe that this should provide market certainty and availability of robust consumer finance packages that, along with the existing 0% VAT rate, will further increase demand for low carbon technologies. Therefore, we ask the Government to quickly deliver its Green Finance Strategy and consider extending the BUS to match the duration of the 0% VAT rate on the installation of heat pumps, which ends in Spring 2027.”

Energy levies “In addition, we urge Government to rebalance energy prices by moving energy levies away from electricity to gas to make heat pumps a more attractive solution for low carbon heating, alongside working

closely with local authorities to raise awareness of the properties that are already suitable for heat pumps and recognise those who make the switch. For those properties that are unsuitable today, Government should look to offer fabric upgrade grants so that homeowners and end users can immediately reduce the heat loss and energy usage in their property, while readying it for a heat pump in the future.

“Whilst the BUS offers homeowners grant funding, the promotion of the scheme and heat pumps as the low carbon technology of choice, needs critical attention. One key area is the education of homeowners about heat pumps, how they work and what consumers should expect when choosing one. At Vaillant, we have identified four pillars that fundamentally need to be addressed to achieve the UK’s decarbonisation targets. These focus on reviewing the fabric of the property first and any upgrades that may be needed to reduce heat loss and therefore energy usage and carbon emissions while ensuring a heat pump will work efficiently.

The next pillar looks at the existing heating system and whether new radiators and pipework are required. The final two pillars are also key to increasing the market

there needs to be a higher level of awareness, confidence, and available finance.

12 APRIL 2023 PROFESSIONAL HEATING & PLUMBING INSTALLER

uptake of heat pumps, which are the education of homeowners and the upskilling of engineers.”

Clear strategy “Amongst installers, specifiers and homeowners there are still common misconceptions around heat pumps. We call for the Government to set a clear strategy on how these can be addressed amongst homeowners. For consumers to have the confidence to proceed with the investment a heat pump system requires, there needs to be a higher level of awareness, confidence, and available finance. Whilst the BUS does not impact Scotland, we can certainly learn from some of the Scottish initiatives, which includes offering an independent advice service for homeowners. For installers and specifiers, we encourage all to attend training on the basics of heat pumps so they can have a foundation of knowledge to help them with their customers’ enquiries. Currently, without consumer awareness and education, installers are not seeing the importance of this training.

“As a technology agnostic manufacturer, we recognise there needs to be alternative options to give consumers choice when it comes to transitioning to a low carbon future. Not every property is suitable for a heat pump and BUS is just one part of the solution for properties in England and Wales. We eagerly await the Department for Energy Security and Net Zero’s response to the questions posed in the inquiry and welcome the opportunity to work with Government to implement changes and improvements for the benefit of all parties.”

INDUSTRY INSIGHT

Bruce Allen, CEO for leading biomass and fuel heating organisations HETAS and Woodsure, is encouraging installers to help educate customers about the latest regulations and best ways to minimise their environmental impact when they seek out solid fuel as an alternative heating solution.

MINIMISE THE IMPACT OF

SOLID FUEL W ith climate change high on the agenda and the cost-of-living crisis persisting, we have seen an unprecedented demand for solid fuel heating. With more homeowners turning to it as a less expensive way to keep their homes warm, wood burning stoves continue to be an essential source of heat. With demand so high, we are calling on installers to help the planet by helping us to educate customers about burning fuel as efficiently, cleanly and sustainably as possible.

As stated in the new Environmental Improvement Plan 2023, domestic burning in England will continue for the foreseeable future. The government recognises that many households are reliant on solid fuel burning where other options may not be viable. However, the new ‘Emissions for air pollutants in the UK’ publication, released in February from Defra, highlighted an increase in burning wood for fuel by 124% between 2011 and 2021. Whilst we

14 APRIL 2023 PROFESSIONAL HEATING & PLUMBING INSTALLER

acknowledge the recent statistics, measures are already in place to tackle these harmful emissions – such as public education and the Cleaner Choice and ‘Ready to Burn’ schemes – and we are confident that, as a sector, we can dramatically reduce these emissions.

Cleaner choices With an increasing number of technologies available, it is vital that we as an industry are never complacent in looking to embrace the latest innovations and promoting the cleanest appliances which will help homeowners lower their carbon footprint on the home front.

Launched just last year was our ‘Cleaner Choice’ appliance scheme. This sets a lower maximum emission level for particulates than the most stringent legislation requirement in current Smoke Control Areas within the Clean Air Act. Stoves must meet current exemption requirements to have attained a listing on

014_PHPI_APR23_Layout 1 06/03/2023 16:12 Page 15

the Defra website, whilst also achieving at least a 50% improvement on current particulate limits required for exemption.

Cleaner Choice is a voluntary scheme open to any manufacturer with the aim of raising consumer awareness through promotion of the best available technology and cleanest solid fuel burning appliances on the market. Alongside this, we only list those appliances that have been independently verified by HETAS as meeting at least a 50% improvement in particulate emissions.

Amongst the cleanest burning appliances are those which use good quality pellets as their fuel source. From our data, we see that most of the lowest PM emissions come from appliances fired by pellet; however, we know that they can be the least popular amongst homeowners. This is possibly due to households favouring wood burning stoves for the aesthetic effect of real flames. But this aesthetic, while traditionally immensely popular, is one approach. Wood pellet burning appliances range from traditional to ultra-modern. These highly efficient and cleaner burning appliances will have a place in our future if we’re to become a nation of net zero homes by 2050.

For those who are happy to focus on low carbon and cleaner burning technology over fashion, pellet-fired stoves can provide busy people with the same levels of convenience as gas central heating

solid fuel remains a vital energy source for many within the UK does. With new technologies that can provide effective combustion control and reduced emissions, pellet appliances really are a win-win situation for the industry, customers and environment alike.

Ready to Burn Burning the right quality fuel is such a simple and easy way for households to reduce their carbon footprint. Yet sadly, many are unaware of the rules around this and are guilty of throwing any old wood in their appliances. Making it easier to burn cleaner fuel is ‘Ready to Burn’ a certification scheme administered by HETAS and Woodsure for Defra. This is where you can really help our cause: by advising your customers to look out for the Ready to Burn mark, they will be armed with the right information and able to easily purchase fuel which is compliant with emissions regulations.

The Air Quality (Domestic Solid Fuels Standards) Regulations, which now apply in England, aim to prevent harmful pollution from domestic burning of all solid fuels by ensuring wood sold in volumes of under 2m3 is certified as having a moisture

content of up to 20%. Fuel quality plays a pivotal role in moving towards a cleaner and safer environment. Improving the standard of wood fuel in the UK is the Woodsure Quality Assurance Scheme.

As well as operating the Ready to Burn wood fuel scheme for Defra, Woodsure assesses and certifies the five most common types of wood fuel, each with different attributes and qualities that provide a flexible range of storage and use options appropriate to differing needs. By advising customers and businesses to purchase from a Woodsure certified producer, they can be assured that the producer has been checked and tested, and that the fuel is delivered at the correct standard for heating systems and appliances.

Whilst we work towards a power particulate emissions and zero-carbon future, we want to bring attention to the fact that solid fuel remains a vital energy source for many within the UK. Until the masses can move to renewable energy on the home front, we within the industry – installers and manufacturers alike – should do all we can to help people make better choices, helping us all move towards a cleaner, safer world.

PART L

– AN UPDATE

Polypipe Building Products takes a look at what installers need to know about Part L of the Building Regulations.

I

n June 2022, updates to the building regulations Part L, which cover the energy performance of new and existing buildings England and Wales, came into force.

Since then, the industry has been in a transitionary period. This means that work on homes with planning approval under the older regulations has been able to proceed as long as it was started within 12 months of the regulations coming into force. However, the transitionary period is now drawing to a close. From June 2023, all projects –

retrofit and new build – will need to adhere to the new regulations. So, now is the time for installers to familiarise themselves with the regulations and the impact that compliance will have on their work.

As we are all aware, the way that we heat our homes is one of the biggest contributors to carbon emissions in the UK. So, the primary aim of the new regulations is to achieve a 31% reduction of carbon emissions in new and existing homes as a precursor to the Future Home Standard due to come into force in 2025.

The Future Homes Standard has been designed to ensure that, on average, new home produce at least 75% less CO2 emissions than a home that has been built to current energy efficiency requirements.

This will mean that all future homes are net-zero ready and will not need retrofitting.

Of course, a reduction on 75% will be no small feat, so understanding and complying with Part L now will provide the industry with a stepping stone towards meeting the government’s ambitious targets.

Lower flow temperature One of the biggest changes to the regulations is that the maximum flow temperature for newly installed heating systems is now 55°C, which is much lower than the previous standard of 80°C. This lower temperature means that the heat emitters in a home will need careful consideration and some radiators will need to significantly increase in size, presenting space and aesthetic issues.

For example, to provide 900 watts of heat output with a flow and return of 45°C/35°C, a double panel radiator would need to be 1800mm L x 600mm H compared to 1000mm L x 600mm H when using 75°C/65°C. This means that it is worth

18 APRIL 2023 PROFESSIONAL HEATING & PLUMBING INSTALLER

018_PHPI_APR23_Layout 1 06/03/2023 16:07 Page 19

looking at alternative emitters that have been designed to run at the lower temperatures laid out in the new regulations.

Alternatives could be heating emitters with a larger surface area, including underfloor heating. As underfloor heating covers a greater surface area, it can run at lower temperatures – between 33-55°C rather than 75°C. This means that the demand underfloor heating places on energy sources is significantly less, making them ideal for use with low temperature boilers and renewables, such as heat pumps. In fact, due to its ability to run at lower temperatures, UFH can perfectly accommodate the optimal coefficient of performance (COP) for heat pumps, which is attained when they run at 35°C. If it’s not possible to achieve a flow temperature of 55°C – which may be the case in properties where there is insufficient space for larger radiators, or where the existing distribution system is provided with higher temperature heat from a low carbon district heat network – then the system will need to be designed to achieve the lowest flow temperature possible, whilst still meeting the heating needs of the property.

A smarter choice Heating controls are another key element of the building regulations. New systems in homes with a floor area of 150m2 or greater will now need a minimum of two independently controlled zones with each room, or zone, requiring its own smart or thermostatic controls. This is because splitting the system into zones means that the levels of heat being emitted in certain areas can be controlled and that residents can choose to heat only the parts of the property that are in use, and turn heating off in any rooms where heat is not required.

As a results, less energy will be wasted.

For traditional convectional heating, this can be satisfied through a thermostat or thermostatic radiator valves on all heat emitters in the rooms that do not have a

the primary aim of the new regulations is to achieve a 31% reduction of carbon emissions in new and existing homes thermostat. For all hot water stores, a timer for heating and timer for hot water is required so that they can be controlled independently of the space heating circuit.

Underfloor heating can be installed in the same way it always has been – no additions required. This is because it is naturally designed and installed into zones.

Therefore, underfloor heating manifolds are able to control multiple zones at once, allowing each area – or room – to be warmed to a different temperature depending on the user’s requirements.

In addition, the pump now needs to automatically turn off when heat is not required. So, the system controls should be wired to ensure that when there is no demand for heating or hot water, the heating appliance and pump are switched off.

Insulating the nation In line with the new regulations, any new pipework will now also have to be insulated.

This includes primary circulating pipes for heating circuits, including those that pass into voids or ducts, pipework for domestic hot water, all cylinder pipework and all secondary circulation pipework. All pipes connecting to a hot water storage unit will also need to be insulated for at least 1m from where they connect to the unit.

In existing systems where the boiler or cylinder is replaced any new exposed pipework must now be insulated. It’s also worth noting that pipes need to be heat pump ready and have at least a diameter of 15mm. Installers will need to comply with this when working on new builds in particular as photographic proof will be required.

As you can see from above, Part L is not just for new builds. Many aspects of the new regulations will have a large impact on how engineers design and install new systems into existing properties. So, it is crucial for any professional operating in the industry to get a firm hand of the updated regulations ahead of the looming deadline in June 2023.

LOW CARBON HEATING

Malcolm Farrow, Head of Public Affairs at OFTEC, says the government’s new energy department faces the same old challenges.

T he low-down ...

F

ollowing a recent cabinet reshuffle, a new Department focussed on Energy Security and Net Zero (DESNZ) has been created to breathe fresh life into the government’s green agenda. The reality is, however, that the existing challenges to delivering low carbon heating across the country remain in an increasingly complex political and economic landscape. That’s why a broader rethink is needed to achieve the UK’s net zero ambitions.

In 2017 the government published its Clean Growth Strategy which set out the foundations to phase out fossil fuel heating in favour of heat pumps. But no one could have predicted the seismic changes that would come down the track, from the pandemic, spiralling energy bills to a cost of living crisis. It’s perhaps not surprising that it’s been difficult to make significant headway, with annual heat pump installation targets being missed.

Today, the central message from the government, echoed by the opposition parties, is the need to deliver growth in the economy and reduce debt – these form two of the five promises outlined by the Prime Minister. This is not just an economic necessity but a political one two with a general election on the horizon. One of the

a broader rethink is needed to achieve the UK’s net zero ambitions central objectives of DESNZ is also to ‘bring down bills’ in recognition of the significant impact rising prices have had on homes and businesses across the country.

It's sometimes suggested that delivering growth and reducing bills is incompatible or in conflict with transitioning to greener forms of energy but this isn’t the case. The two can work hand in hand, but only if the government

20 APRIL 2023 PROFESSIONAL HEATING & PLUMBING INSTALLER

rethinks its current low carbon approach.

In its Heat and Buildings Strategy, the government proposed banning the installation of replacement fossil fuel boilers in domestic properties and smaller commercial premises off the gas grid by 2026. The same applies to larger businesses but with a shorter deadline of 2024. In most cases properties will be expected to switch to a heat pump. But with such a tight timeframe the UK will likely still be in – or feeling the after effects of – the cost of living crisis. This means net zero policies must be aligned with the current economic landscape – we can’t continue on the existing course and hope the economy is in a better place.

Core principles What does this mean practically? To succeed, decarbonisation policy must focus on achieving two core principles: a rapid transition to low carbon heating in an affordable way. Up until now, the discussion has been on committing to a technology (heat pumps) and trying to make them work in the current economic and social landscape. This approach needs adapting to focus on the above outcomes and determining the best technologies to achieve this.

GENERAL_Layout 1 06/03/2023 18:22 Page 21

씱 The renewable liquid fuel HVO is a near drop in replacement for existing oil heated properties where heat pumps are not a viable solution

That’s why we strongly believe in a technology neutral approach. Heat pumps have an important role to play and OFTEC registered technicians are already completing our training courses and installing the systems in suitable properties. However, we recognise that not all homes and businesses are the same – particularly off-grid. Older housing stock often requires extensive renovations from new radiators, the reintroduction of a hot water tank, changes to pipe work, or other energy efficiency measures for heat pumps to work efficiently. For some homes, the government’s calculator estimates the cost could exceed £20,000.

This clearly isn’t viable. That’s why we need a multi-faced approach.

Renewable Liquid Fuels Renewable Liquid Fuels such as Hydrotreated Vegetable Oil (HVO) provide a realistic alternative solution for oil heated

buildings that are ill-suited for a heat pump. With a minimal transition cost and a hassle free conversion process, emissions can immediately be reduced by 88%. Just under 150 properties have switched from kerosene to HVO as part of a demonstration project which has been a complete success, with high levels of support from participants. We now just need the backing of government to create a competitive market for HVO. 2023 is a hugely significant year when the right decisions have to be made, as we head towards the first 2024 deadline in the Heat and Buildings Strategy, and we enter the next general election window.

We can have the best of both worlds: delivering net zero and stimulating economic growth by not pushing households into further financial hardship.

But to achieve this we must be honest, recognise the challenges we face and adjust course.

LOW CARBON HEATING

TACKLING THE

CHALLENGE

Mitsubishi Electric has called on the construction industry to tackle the low carbon heating challenge.

Domestic and Light Commercial

H

eat pump manufacturer, Mitsubishi Electric, is calling on the construction industry to come together to address the UK’s need to quickly transition to low carbon heating – as it launches what it believes is the widest range of commercial and residential heat pumps on the market.

The company said that achieving the Government’s ambitious target of 600,000 heat pump installations a year by 2028 will require a tenfold increase in the number of installations over the next five years, presenting a significant opportunity for businesses throughout the supply chain to help customers in the transition to low-carbon heating.

Russell Dean, Director of Residential Heating Systems

New products Mitsubishi Electric is adding to its renewable heating range to support this ambitious target. The most recent products from the company include two new commercial heat pumps with the MEHP-iS-G07 heat pump chiller from the company’s Italian factory, and the new Ecodan CAHV-R air source heat pump, which updates the CAHV-P model and uses R454C refrigerant, with a lower GWP (Global Warming Potenital) of 148.

“In the commercial sector, there is now a strong case for renewable heating and businesses are aware of the need to move from gas, with many actively planning this in their annual budgets,” explained Philip Ord, Director of Commercial Products. “The heat pump industry is therefore pushing against an open door but we need to give specialist support to the whole supply chain on just how this is practically achieved”.

22 APRIL 2023 PROFESSIONAL HEATING & PLUMBING INSTALLER

The new commercial products join the Ecodan Ultra Quiet residential air source heat pump range and the Ecodan Hydrodan water-to-water heat pump, launched last year, which works with fifth generation, low temperature heat networks. The company has also promised further additions to the domestic Ecodan line-up later in the year.

“We have a wide range of ultra quiet heat pumps ideal for anything from homes to light commercial use. The challenge now is to look at ways of maximising the efficiency of the buildings they are being installed into,” commented Russell Dean, Director of Residential Heating Systems.

Mitsubishi Electric is also developing its Ecodan range by working closely with its Scottish manufacturing plant to deliver systems that match the needs of British homes.

“We can now provide a heat pump for anything from a small, modern home right up to a 1000+kW heat pump chiller that will service a school, a leisure centre, a hospital, or an entire university campus,” added Martin Fahey, Head of Sustainability.

Changing the way we heat buildings Heating accounts for almost a third of all UK carbon emissions, so changing how we heat our buildings is a critical part of tackling climate change and reaching net zero. Although modern heat pumps have been available for over a decade, the renewable heating market is still in its infancy. However, the company believes

022_PHPI_APR23_Layout 1 06/03/2023 16:42 Page 23

The Ecodan PUZ air source heat pump

With a flow range from 25°C to 60°C the Ecodan PUZ air source heat pump is available from 5kW to 86kW. Ecodan models are self-contained units and only require water and electric connections. They are low maintenance, quiet to run and can be placed outside homes. Models are also suitable for light commercial situations.

We need to quickly transform the landscape for heating by decarbonising the way we provide heat to homes and businesses

that the industry needs to come together and find ways to apply heat pumps as quickly as possible.

“We need to quickly transform the landscape for heating by decarbonising the way we provide heat to homes and businesses,” said Martin Fahey. “We also need to make sure that we use the right products for the right application, and this is where education, training and support play such an important role”.

“As a manufacturer, we’ve responded by developing what we believe is the most comprehensive range of heat pumps for almost any building in the country,” added Russell Dean. “We’ve also quadrupled the amount of training available for plumbers and heating engineers and made it easier for them to learn how to apply renewable heat pumps in different situations.”

The company believes that by announcing this comprehensive range of renewable heating systems it can help construction companies, building owners, contractors and installers across the industry to reduce running costs, improve energy efficiency and lower carbon emissions.

“The age of the heat pump is upon us and the products are available now,”

explained Philip Ord, “the challenge is how we work together to increase the number of renewable heating engineers and ensure that every building can benefit”.

LOW CARBON HEATING

FEEL THE Warmth Warmflow explains how its Zeno Heat Pump and Nero Hot Water Cylinder were recently used to help create a sustainable and environmentally friendly home.

A

ward-winning manufacturer Warmflow has helped to boost the energy efficiency of a new build house with the fitting of its new Zeno air source heat pump.

Property owner Mrs Fergerson set out to create a sustainable and environmentally friendly home which was practical, sleek and modern. Alongside much more to consider, she wanted a clean heating source that would efficiently and effectively heat her home as well as being environmentally sustainable. “I wanted a heating solution that would keep my warm, provide me with hot water as well as being environmentally friendly, and Warmflow Zeno Air Source Heat Pump ticked all the boxes.”

24 APRIL 2023 PROFESSIONAL HEATING & PLUMBING INSTALLER

Touchscreen control Installer Richard Bentley recommended this heat pump as one of the most intelligent and efficient heat pumps on the market. “The customer wanted the heat pump installed alongside a Warmflow Nero Hot Water Cylinder, this solution provides both heat and hot water. I selected the AS03 model of the Zeno heat pump range in order to meet the size demand of the property. The unit was dead easy to install and commission with the very clear, easy-to-use touchscreen controller. The unit itself also looks really well and suits the house perfectly.”

The home is 300m2, with 240m2 being heated living space. The solution to heat this large new build was the Zeno AS03

024_PHPI_APR23_Layout 1 06/03/2023 18:04 Page 25

which outputs 20kW of heat energy, providing hot water temperatures of up to 60˚. This supplies the underfloor heating throughout the whole ground floor.

Alongside the AS03 heat pump, the installer chose a Warmflow Nero 300 litre Hot Water Cylinder.

Renewable heating In addition to the natural wood cladding and renewable heating solution, this project also planted a tree in the heart of the building, providing a mini utopia. The building work was carried out and completed by Best Little Building Company.

GB Renewables Sales Manager Niel Rumbold said: “The Zeno Air Source Heat Pump units are a brilliant heating solution for new builds. They offer excellent energy savings and can help reduce the end user’s carbon footprint.”

He added: “In this case, the homeowner wanted a more energy-efficient and environmentally friendly heating solution for her home, and she has expressed her delight at the results. Underfloor heating had already been installed in the property, and heat pumps and underfloor heating systems pair together very well. This is because the underfloor heating requires lower flow temperatures of 35 degrees, meaning the heat pump in turn uses less electricity.”

Warmflow’s range of air source heat pumps harness natural heat energy from the air and offer features such as Warmlink – a remote control and diagnostic platform which comes as standard with all Zeno heat pump models. The installing engineer simply downloads the Warmlink app onto their phone, scans the unique QR code on the side of each appliance and is then able to remotely monitor, fault find and control the unit from anywhere in the world.

Warmflow also offer installers the chance to receive training in one of its seven training centres across the UK, which give in-depth training on the company’s Zeno Air Source Heat Pumps.

Training involves installation, commissioning & troubleshooting.

Warmflow’s new Renewables Sales Manager Known for its Zeno Air Source Heat Pumps, Warmflow has welcomed a new Renewable Sales Manager for GB, Niel Rumbold. Niel has been in the renewables sales industry since 2014. He said: “I wanted to work for Warmflow because of their excellent renewable products which are great value, excellent quality and very innovative. Their Zeno Air Source Heat Pump is one of the most intelligent and efficient heat pumps in Europe and come with many great benefits, including the cloud-based app, Warmlink, which allows for quick diagnostics and control of the unit, which is a game changer! Being an ex-engineer, I appreciate the detail and installation benefits that come with this product.”

The new Warmflow Nero Cylinders

The New Warmflow Nero Heat Pump Cylinders are designed to work in tandem with the Warmflow Zeno range of air source heat pumps and have changed in colour to better match in with the look of the heat pump creating an overall aesthetically pleasing appearance.

Nero Cylinders are supplied with the necessary parts for a quick, easy & professional installation. Warmflow factory fit the temperature and pressure relief valve as well as cylinder thermostats for convenience & safety.

The New Nero cylinders are available in Indirect, Twin coil, Triple coil, Direct and Heat Pump models. They come in volumes from 110 to 290 litres, with a duplex steel construction and grey leather grain casing with high performance rigid coils.

LOW CARBON HEATING

TIME FOR RENEWABLES

Andy Smith, National Sales Manager of Grant UK, looks at how to move your business towards low carbon installations, such as heat pumps.

P

lumbing and heating engineers can transform and potentially future proof their business by embracing and offering renewable heating systems to homeowners. In the latest public attitudes research from the Department for Energy Security and Net-Zero (formerly BEIS) in 2022, awareness among the public of air source heat pumps has reached 71% and legislation, such as the Building Regulations, is encouraging more installations of low carbon heating technologies.

Many installers are now on the journey towards incorporating air source heat pumps into their business offering and Grant UK has witnessed this first hand training engineers and supporting them with installing low carbon heating systems.

Lewis Gould Plumbing & Heating, based in Aberhonddu, Powys, is one such company.

26 APRIL 2023 PROFESSIONAL HEATING & PLUMBING INSTALLER

Its transformation towards installing low carbon heating involved training and on-site support from Grant UK, and the installer’s decision to move into renewables has paid off.

Like many plumbing and heating businesses, the company, which was established in 2009 by Lewis after he had been working for four years as a local installer, initially focused on oil and gas work and bathroom installations. It is OFTEC registered and works in the surrounding areas of Aberhonddu.

Lewis has known John Morris, Grant UK’s Regional Sales Manager for the West, for quite some time and due to oil work being a major part of their business, Lewis had worked closely with Grant boilers and installed many of the Vortex models over the years.

026_PHPI_APR23_Layout 1 06/03/2023 18:01 Page 27

Many installers are now on the journey towards incorporating air source heat pumps into their business offering Hands on training Some time ago, John had introduced Lewis to Grant’s first air source heat pump and he completed their product training course straightaway. It proved to be a good base of knowledge and with changes in the market and the growing demand for renewable heating over the past few years, Lewis and one of his colleagues attended the latest Grant Aerona³ Air Source Heat Pump product training course in June 2022, at Grant UK’s Training Academy in Wiltshire.

Lewis and his colleague found the two-day course very informative, with plenty of hands-on opportunities to work on the Aerona³ unit, Grant UK’s latest generation of heat pump. The course tutor was knowledgeable and assisted with all questions, allowing them to feel confident about installing and working with air source heat pumps.

Barn conversion Lewis’s first heat pump installation was a barn conversion in Brecon, which required a complete heating system to be specified and installed. The local Area Sales Manager from Grant UK, Stuart Thompson, carried out the site survey at the beginning of the project. Grant UK’s in-house Design Team then specified the system and supplied the list of products needed for the project.

The installation included an Aerona³ 10kW air source heat pump, a Quick

Recovery 250ltr pre-plumbed hot water cylinder, and a Combined Low Loss Header/Volumiser. The wiring and plumbing diagrams were provided in advance and were simple to follow. The pre-plumbed cylinder was easy to fit, and the low loss header was straightforward to install and helped with the hydraulic separation of the system.

Set-up service Lewis also opted for the heat pump setup service, which was free following the product training course. Jess York, one of Grant UK’s Field Service Engineers, assisted with the set up and commissioning, giving Lewis peace of mind

with his first heat pump installation.

Air source heat pumps are now part of the company's product offerings, and Lewis is advertising their heat pump installation services locally. The company is a G1 approved installer for Aerona³ air source heat pumps and is listed on the Find an Installer search on Grant UK’s website.

Moving your business towards low carbon heating solutions is achievable and with legislation encouraging the uptake of heat pumps and an increased awareness of low carbon heating among homeowners, now may be the time to start your journey.

WATER PERFORMANCE

Salamander Pumps has introduced its latest water boosting solution, TankBoost, designed to deliver water pressure and flow in homes and light commercial buildings.

N

o matter the size of the household or the number of outlets running in the kitchen or bathroom, good water pressure and flow is a must have for homeowners. One of the UK’s leading manufacturers of water boosting solutions, Salamander Pumps, has launched TankBoost, designed to be an easy to install, single unit solution to ensure water performance remains at optimum levels even in large, multi-storey homes.

TankBoost will deliver flow rates up to 80L/min and pressures up to 3.0 Bar, suitable for homes where showers, taps, toilets and more are being used at the same time.

The latest product in the expanding MainsBooster range, TankBoost combines a cold water storage tank and an integral pump. The high-quality stainless-steel pump is submerged within the tank, and the company says that this means that TankBoost is extremely quiet throughout operation.

80 L/MIN

TankBoost will deliver flow rates up to 80L/min and pressures up to 3.0 Bar

30 APRIL 2023 PROFESSIONAL HEATING & PLUMBING INSTALLER

Exciting extension Tank Boost has been designed to meet the water pressure and flow needs of domestic and light commercial installations, with four tank sizes available ranging from 100L to 450L. Additional storage tanks are also available to increase capacity for large properties or those with particularly low incoming flow rates.

The company says the solution will overcome insufficient water pressure and flow in combi or unvented systems.

Gareth Richards, Technical Director at Salamander Pumps, said: “Our new TankBoost product is an exciting extension of our MainsBooster range, which has been developed to ensure multiple outlets receive sufficient water all at once.

“It’s a stand-alone, cost-effective solution that can be trusted to ‘run the show’ – working hard to meet the water performance challenges that often occur when multiple outlets are running at once, e.g.in larger, multi-storey properties, such as extended homes, HMOs, social housing settings, hotels and B&Bs.”

030_PHPI_APR23_Layout 1 06/03/2023 18:15 Page 31

TankBoost will give even the busiest of properties more than enough boosted water supply.

More flow TankBoost is the first product in the Salamander Pumps product range to deliver flow rates beyond 36 L/min, promising powerful showers, strong flowing taps, and quick toilet cistern replenishment, even when they are being used at the same time.

The company believes the typical application for the product is a larger dwelling, with several floors and bathrooms. However, it says that TankBoost can also service smaller properties due to its compact size.

Gareth added: “TankBoost will give even the busiest of properties more than enough boosted water supply. We’re already seeing a lot of anticipation for this launch with significant interest from installers,

merchants and homeowners.

“We’ll be providing comprehensive guidance to support plumbers with the specification and installation process in the form of webinars, step by step guides and e-school content.”

Link up TankBoost is initially available in four different sizes, from 100L to 450L, meaning solutions are available for properties of all sizes. Where a property has particularly high water demand, and space is not an issue, tanks can be linked with additional storage units to increase capacity.

CAT5 variants and additional water storage tanks are also available as part of the range, and the product comes with a two-year warranty.

Time saving

PanelShow

Installation is a big part of a project and any time that can be saved during this stage is key. For this reason, those in the trade should be looking for easy and fuss-free installation options, helping to save time and labour on site. This also benefits the end-customer too, minimising disruption and enabling them to enjoy their newly finished bathroom, sooner.

With installation in mind, wall panels are faster to fit when compared to tiles. This is due to several reasons, such as the fact that wall panels are capable of being fitted directly on top of existing tiles, with minimal surface preparation required. Alternatively, they are also suitable for installation onto plasterboard or stud partitioning.

Additionally, there are no specialist tools or skills required to fit them, with the panels able to simply be cut to size and glued (or screwed) into position. This is especially important considering the ongoing labour shortages, with experienced tilers often being highly sought after and potentially causing delays to jobs.

Wall panels are also easy to store and transport, with less chance of damage during travel.

Test of time

Tiles have often been the go-to for bathroom installations, but this doesn’t mean they are the only option. Scott Beattie, Managing Director at Fibo, explains the benefits of opting for waterproof wall panels.

F

or many, the bathroom is a haven, a welcoming and relaxing space instead of a purely functional room. To help customers achieve this, it’s important to use materials that can not only fulfil the technical requirements – such as speedy installation and long-lasting durability – but also be aesthetically pleasing.

For years, tiles have been the standard choice for bathrooms. However, waterproof wall panels offer a great alternative to tiles, providing numerous benefits for installers and consumers.

Another critical factor for installers to consider is whether the product they’re fitting will stand the test of time. This is especially important for bathrooms, one of the busiest rooms in any home. With this in mind, durability is key.

Most high-quality wall panels are manufactured with a multi-layered plywood core, providing a strong, durable and long-lasting system. Look out for products with a tongue and groove joining system, such as Fibo’s Aqualock, helping to create a strong and reliable watertight join. This will protect the bathroom from damp and leaks, further increasing the lifespan of the room and reducing the likelihood of call-backs.

YEARS

Fibo offers a 25-year warranty on all of its panel systems, providing they are fitted properly according to the installation instructions Many wall panel systems are available with a 10- or 15-year guarantee, giving you and your customers the added assurance of performance. Fibo takes this one step further, offering a 25-year warranty on all of its panel systems, providing they are fitted properly according to the installation instructions.

Range of designs Given the transition from functional to beautiful, appearance is everything. This is another area in which wall panels excel, with a wide range of styles, decors and colours available to choose from, meaning your customers can pick the exact design they want.

With wall panel manufacturers taking inspiration from current interior design trends, you’re able to find decors that are inspired by biophilic design, with blues and greens or authentic wood effects reminiscent of nature. There are also different tile patterns on offer, such as metro brick, hexagonal and straight herringbone.

This all helps to feed into the idea of a bathroom being more than just a functional space, but also one to get creative with the colours and styles that are chosen.

For those who remain sceptical about moving wholly away from the aesthetic of tiles, it’s good to know that there are realistic tile-effect wall panels on offer.

These come with realistic grout lines and a high gloss finish. Some manufacturers even go as far as to router in the grout lines to create a 3D effect, resulting in a panel that not only looks real but feels real too.

When it comes to bathroom installations, tiles have long been the traditional choice. However, the increased popularity of waterproof wall panels demonstrates that it is perhaps time for a change. With endless benefits for installers and residents, it’s clear to see why they’re becoming a popular alternative.

PUSHING THE

GreenAGENDA

Richard Bateman, Product Marketing Manager at RWC, examines how plastic push-fit technology is a step towards a greener plumbing future.

F

rom swapping fast fashion for charity stores to adopting a more plant-based diet, there are many steps that we are all taking in our effort to be more environmentally friendly. Indeed, many people are set on having a more sustainable household overall, and one area that should certainly not be overlooked is the house’s plumbing system. Whilst the UK Government is actively taking strides towards new sustainable targets, there are no guidelines listing what materials should be used in plumbing systems.

Decreased connections Plastic push-fit fittings can reduce the complexity in pipework by decreasing the number of connections required, which can save water long term by reducing the chance of leaks. One example would be the plastic push-fit plumbing manifolds, which by establishing a single central hub as a distribution point for either hot or cold

Twist & Lock provides an instant, flame-free, push-fit connection, that can be installed and demounted in seconds without tools

water supplies, simplify pipework. Without the need for additional fittings, a single run can be cabled to an outlet by using JG Speedfit Polybutylene pipe. In addition to limiting leak points, this makes maintenance simple. Seeing as a single leak can lose up to 1,400 gallons of water in 24 hours, you really do want to take as many steps as possible to prevent them from happening.

36 APRIL 2023 PROFESSIONAL HEATING & PLUMBING INSTALLER

Additionally, the specialised push-fit valve range from JG Speedfit, which bring together different functions into one fitting that saves space and installation time are a great way to make a plumbing system greener too. Double check valves combined with service valves for outside taps can save a lot of space under the sink, for instance. There are also lever-operated shut off valves, hand-operated shut off

036_PHPI_APR23_Layout 1 06/03/2023 17:49 Page 37

taps, or screwdriver-operated valves that can shut off water supply with a single turn.

The capability to isolate water supplies, inherently reduces the need to drain water off the whole property. This then helps to save gallons of water should servicing and maintenance be required on the plumbing and heating system.

An example of plastic push-fit’s green credentials is the JG Speedfit Twist & Lock range, which, like the aforementioned second fix range, is up to 40% faster to install than traditional methods and are easier to use in confined spaces by removing the need for hot works and tools.

Like all other push-fit fittings Twist & Lock provides an instant, flame-free, push-fit connection, that can be installed and demounted in seconds without tools. This is largely due to the fittings’ Grip & Seal collet with stainless steel teeth and its main O-Ring seal.

Furthermore, the polybutene plastic is a non-toxic material, that resists both corrosion and scale build-up. This ensures that the fittings are watertight and long lasting, preventing any need for repairs and providing a more environmentally friendly plumbing solution overall. The fittings are available in multiple key bends such as straight connectors, tee tube connectors, and equal elbow connectors, which ensure you can push the green agenda from every angle.

Issues with underground pipework are usually a result of one of two issues, if not both. A myriad of environmental factors mean that it is difficult for installers to determine whether a watertight seal has been made upon first installation, particularly if using fittings with compression connections; or the fitting can become loose over time, which then causes leaks that are hard to rectify.

These risks are significantly reduced with plastic push-fit MDPE fittings like those in the JG Speedfit range. Like all plastic push-fit fittings, the fitting is sealed by simply pushing the fitting into the pipe, which drastically reduces the chance that the fitting will be insufficiently installed upon first installation.

Underground leaks can be extremely laborious to deal

with; ground needs to be dug up to identify problems, which requires specialist machinery. Push-fit MDPE fittings assure a reliable and leak-proof seal, and with the JG Speedfit range, the installation is right first time. This of course makes for a longer lasting and more environmentally friendly system overall. Ensuring that water is conserved for years to come.

By requiring fewer repairs from installers, a reduced installation time, and by providing a leak resistant connection, plastic push-fit fittings provide a long-lasting and environmentally conscious plumbing solution, which ensures that homes can remain sustainable for years to come.

Chris Billingham, Head of Marketing & Innovation for Methven, looks at how the bathroom products market has shifted to respond to the cost-of-living crisis and how performance without compromise can still be achieved in a difficult economic climate.

SHOWERING PERFORMANCE T

he recently announced news that water bills are set for the biggest increase in almost 20 years from April is yet another financial issue for individuals and businesses across the UK to come to terms with. According to industry body Water UK, the annual bill for an average household in England and Wales will hit £446, meaning if it wasn’t the case already, all eyes are going to be on ways to cut down on bills where possible.

All consumers, whether refit or refurb are looking to save money in the current climate, and this is an added incentive to do so – however, it doesn’t mean that they must suffer in terms of performance.

Reduce energy usage We are in a new era where installers and customers can select from a range of products to help reduce bills and energy usage. But at what cost to performance?

The wider public’s understanding of the importance of energy efficiency within the home and the wider impact this can have if we all focused on making small changes in the home – and particularly in the bathroom is shifting. This greater societal environmental awareness has coincided with – and in turn encouraged – a shift in focus from product manufacturers.

we believe in providing people with the tools to educate themselves on how to make the smart choice when it comes to water-saving products.

38 APRIL 2023 PROFESSIONAL HEATING & PLUMBING INSTALLER

While efficiency, performance and cost have always been a tricky trio to balance, Methven offers customers performance without compromise at a time when it is needed most.

Water saving Our history began in New Zealand and prior to entering the UK market, we have spent decades innovating in the Australia continent, where water saving measures have been a legal requirement for many years. This insight and experience is invaluable when it comes to creating products to suit the needs of the installer and their customers.

A water efficient shower head is a relatively low-cost upgrade which can make a real difference.

At Methven, our production is driven by the need to future-proof homes and reduce water and energy usage, all without any compromise on performance.

038_PHPI_APR23_Layout 1 07/03/2023 10:12 Page 39

Invigorating shower Our patented technologies, Satinjet and Aurajet for example, operate at just eight litres per minute providing customers with an invigorating shower that doesn’t compromise on performance, compared to standard shower heads that can use up to 15 litres per minute if unrestricted.

As well as focusing our efforts on ensuring our products are as efficient and easy to install as possible, we believe in providing people with the tools to educate themselves on how to make the smart choice when it comes to water-saving products.

Online calculator Towards the end of 2022, we launched our online Water Saving Calculator, to show homeowners and developers how switching from a conventional needle jet shower to a water saving showering technology can help save money.

It utilises details such as the number of people in a household, existing shower flow rate and showering time, before advising a suitable handset to reduce water bills – we have seen in many cases that this can be by up to £400 a year, which would almost completely negate the proposed average increase according to Water UK. At Methven we are committed to conserving energy and water around the world to protect the planet for generations to come.

Improvements in urinal flushing controls over the past 20 years mean that significant water savings can be achieved when urinals are upgraded – and with many organisations aiming to become more water efficient, this can increase opportunities for plumbing installers. Martyn Andreoli, National Sales Manager at Cistermiser, explains more.

U

rinals are a standard feature in commercial and public sector washrooms, being functional as well as easy to clean and maintain.

Fortunately, due to improvements in flushing controls, urinals are quickly becoming more water efficient – which is encouraging building owners and managers to upgrade and refurbish their facilities.

The need to save water has become a more prominent issue in recent years.

According to Waterwise, population growth, rising water use and climate change will increasingly affect future water resources in the UK, and if water efficiency action is not improved, the country could face water shortages by 2050.

Many businesses and public sector organisations are proactively investing in water saving solutions to help them meet

environmental standards or gain BREEAM credits. Becoming more water efficient also helps to lower water bills – most non-household premises have water meters to measure consumption, on which water bills are based. As the appetite to increase water efficiency grows, so do the opportunities for installers.

Significant savings Washrooms are an ideal place to start, and urinals offer the potential for significant savings. While they generally use less water than toilets (because they require a smaller volume of water for flushing), their water consumption remains significant – in offices accounting for approximately 20% of water use, and traditional flushing systems potentially using upwards of 850 litres of water a day. Modern flushing technologies can offer significant reductions in water consumption and

40 APRIL 2023 PROFESSIONAL HEATING & PLUMBING INSTALLER

costs – indeed, thousands of pounds per year could be saved.

A range of solutions are available, and it’s important for installers to understand how they perform so they can best advise their customers, ultimately helping them to reduce their water consumption.

Urinal operation The way traditional urinals operate wastes water; the flushing cycle would be set by adjusting a petcock fitted in the cistern’s inlet pipe – this would match the typical

040_PHPI_APR23_Layout 1 06/03/2023 17:44 Page 41

When urinals are refurbished, the primary consideration for the building owner or manager is likely to be to reduce water consumption.

Sensor-controlled valve The most comprehensive solution – offering greater potential for savings – is a direct, mains-flushing sensor-controlled valve. Individual urinal bowls are automatically flushed after each use and the need for a cistern is eliminated – ensuring the highest level of hygiene while still conserving water. When the sensor detects a person, water is released for flushing. Direct flush systems can be powered by mains electricity or batteries.

Our direct flush products can reduce water usage significantly, with a return on investment potentially achieved in just eight months.

Infrared control valves usage pattern but wouldn’t take account of changing occupancy levels. So even if a building was vacant, intermittent flushing would continue, typically wasting significant litres of water.

This inefficient flushing technique is no longer available for new systems or upgrades, following the introduction of The Water Supply (Water Fittings) Regulations 1999. The regulations put stipulations in place to limit the amount of water that flushing devices are allowed to use, as well as requirements for isolating valves and time controls. In addition, flushing arrangements will need to incorporate a backflow prevention arrangement or device, again laid out in the regulations.

Various solutions are available that meet regulations (installers should look for WRAS approved products) while also being simple and straightforward to install.

The type of solution selected will largely depend on the property’s water pressure, whether a mains supply to the urinals is available, if there is an existing cistern to retain, and the customer’s budget.

Infrared control valves are a great alternative if a cistern is installed. A small amount of water is released into the cistern every time a passive infrared sensor (which is installed on pipework, walls or the ceiling) senses movement around the urinals. Once the water in the cistern reaches a set level, the urinals are automatically flushed.

Again, these can be powered by mains electricity or batteries. Our infrared control valve (IRC) can minimise water usage by 80% when used in standard mode compared to a petcock system and offers a return on investment of 10 months – this can be further enhanced by using the eco mode.

therefore potentially the urinal) is being used. Flushing occurs once the water in the cistern reaches a set level. These controls can potentially reduce water use by over 75%. They function at different water pressures and do not require an electrical supply or battery power. Modern flushing solutions can usually be configured to incorporate hygiene flushes, which reduce odours when washrooms are not in use.

Flush-free In addition, installers may be aware of the flush-free urinals on the market, which rely on chemicals. While they might be beneficial in certain environments (where space is highly limited for example), they are likely to require more day-to-day maintenance than conventional urinals.

When urinals are refurbished, the primary consideration for the building owner or manager is likely to be to reduce water consumption. By understanding more about what’s on offer and the potential water savings that can be achieved, plumbing installers can be in an ideal position to take advantage of the opportunities available.

Hydraulic control valves Meanwhile, hydraulic control valves provide a ‘fit and forget’, simple, reliable solution. They are installed in-line with the inlet pipe to an auto-siphon urinal cistern which will only fill and can only flush when the washroom is in use. A measured amount of water is released into the cistern every time the water pressure drops, as this indicates the washroom (and

TAKE TO THE

FLOOR

Bosch Commercial & Industrial has introduced a new floor-standing commercial boiler range.

A

new floor-standing boiler range has been introduced by Bosch Commercial & Industrial, designed for the installer and centred on speed and efficiency. Built to replace the Worcester Bosch GB162 V2, the Condens 7000 F & FP features a new design developed with simplicity in mind. The company believes installers can expect to save up to 60% on average installation times when fitting the new range when compared to the GB162 V2.

The new narrow frame is built for easier access and includes a transport roller accessory for ease of mobility, particularly for rooms where space is limited.

This is thanks to a new frame kit design, simple install steps with minimal tools required and an easily accessible PCB. The range is available as either a single boiler or a cascade pack, which suits a wide variety of system outputs and hydraulic requirements.

Thanks to an output range from 75kW to 1MW, the boilers can be cascaded to

meet higher outputs with the ability to combine 16 boilers while using a Bosch 8313 control.

This means the range can reach up to 8MW output for large commercial applications.

The Condens 7000 F & FP can be fuelled on both natural gas and LPG with all outputs able to run on a 20% hydrogen blend. This model has an integrated Internet interface, making it convenient to control remotely using a smartphone or tablet with EasyRemote or HomeCom from Bosch.

Less complexity Simon Tarr, National Projects Director at Bosch Commercial & Industrial, commented: “Our new range has been developed with installer’s time in mind. We have taken the complexity away from each step of the product journey. When specifying, each pack contains all the base components required, sitting under one part number.

This enables installers to easily receive a quotation from their local Merchants.

“Whether you are specifying with Bosch

42 APRIL 2023 PROFESSIONAL HEATING & PLUMBING INSTALLER

in mind, or if you are looking for multiple quotes from different manufactures to work out the best value for the job, we have made this process simple. Packs are available as either as a single pack, or cascades of multiple boilers with various hydraulic options.

“When it comes to installing, and while obtaining customer feedback during our research and development phase, we saw an installer on average assembling a two-boiler cascade in less than 20 mins on their first attempt. The installation is very intuitive and shows a real evolution to cascade frames.

“Finally, we’ve created an online pre-commissioning checklist where installers can now book commissioning directly through us, ultimately streamlining the process. We hope that all these time-saving measures add up to give installers and contractors more time to focus on either additional jobs, wider business admin or just free time to enjoy.”

PRIMING THE

PUMP More and more, installers and contractors are being asked to upgrade heating and hot water circulator pumps to offer better energy efficiency as the push toward Net Zero continues. David Williamson, Sales and Marketing Director from Wilo UK looks at how to specify light commercial pumps and what to consider when it comes to installation and maintenance.

44 APRIL 2023 PROFESSIONAL HEATING & PLUMBING INSTALLER

n many legacy buildings, heating and hot water circulator pumps are often ‘of an age’, work at one speed only, and operate in silo to other building services.

These pumps are typically fixed in speed, use highly inefficient AC motors and offer one mode of operation – either on, or off.

Technology like this simply cannot compete, whether it’s in efficiency, performance, functionality, ease of use, installation or maintenance. Building owners, managers and those with responsibility for running buildings are recognising this, and with the continual journey toward Net Zero, many are now seeking to upgrade these old pumps for newer ones.

This movement is in turn opening up more opportunities for installers and contractors to act as the vehicle to make these improvements happen. However, with a plethora of choice available, simply choosing a circulator pump in itself can be a minefield, let alone then fitting in old buildings and then putting in maintenance plans for these products. To negotiate these challenges, it is imperative installers understand what modern pumps are capable of, and how they can assist them in their jobs.

Specification Heating and hot water circulator pumps today have many more capabilities compared to old pumps. There has been a lot of innovation in recent years, but the biggest is arguably the advance of electronically commutated (EC) motor technology.

044_PHPI_APR23_Layout 1 06/03/2023 17:28 Page 45

To put this into perspective, switching from a circulator pump with an AC motor to one with an EC motor instead will provide an immediate 30% reduction in energy use.

It’s not just EC motor technology that makes circulator pumps efficient though – many of these newer pumps are built with variable speed drives on board. When coupled with variable speed capability and controls, pumps can then become much ‘smarter’ in operation, and work at lower speeds too, meaning energy savings can be increased to approximately 60%.

Some pumps, like the Wilo-Stratos MAXO or the Wilo-Stratos PICO, can also ‘learn’ the operational characteristics of a heating or cooling system. They do this by using Wilo’s Dynamic Adapt Plus and Multi-Flow Adaptation technology. The former allows the pump to continuously adjust and maintain peak performance as system dynamics change, while the latter facilitates communication between the main pump and any secondary pumps within a system. With both, installers can configure and ensure the circulator pump adapts in real-time to demands and works holistically with other building services.

Installation Helping to choose a pump may just be one part of the equation for installers and contractors, and typically, some of the biggest challenges of these projects is on-site when it comes to demounting and

installing the new pumps.

In an old ’light commercial building’, such as a small office block, retail units and restaurants, installers may encounter all manner of unforeseeable, challenging scenarios. This includes poor planning and space management with pipework, tight airing cupboards, plant rooms or service risers, all of which serves to limit access and test installers. Along with this, original plant within these spaces may have been altered and added to, further complicating matters.

Here is where a well-designed product can make all the difference. Big, bulky and heavy pumps will undoubtedly lead to knocks and scrapes and may mean more unnecessary work with getting it to fit.

Modern pumps like the Wilo-Stratos MAXO meanwhile are small in footprint, meaning they can help get around these issues, and lead to a quicker completion time. The pump also overcomes traditional headaches of connecting the electrics through its clearly arranged, easily accessible terminal.

Another area to be mindful of is commissioning. Too frequently, poorly thought-out pumps make this step more confusing than necessary. Small analogue displays and manual setting all serve to slow installers down. Here, smart modern pumps like the Wilo-Stratos MAXO can do away with this hassle for installers with one-click commissioning and a settings assistant for pre-set applications, along with a large digital display and intuitive user-interface. Pumps can also come with Bluetooth connectivity too, which is useful if pumps are located at a high level or in small plantrooms – and an added benefit is that with Bluetooth, settings can be copied to other pumps or retained for future use.

Maintenance By introducing a smart pump into the building, not only does it help with long-term energy efficiency and aid an easier set-up, it also means that returning to a site to undertake maintenance and servicing is much simpler too.

With old, fixed speed pumps, it may only become apparent that there is a problem with them after the heating or hot water has started to malfunction, at which point it is too late and a building, especially a commercial one, cannot afford to take such risks. Newer pumps are equipped to mitigate these issues before they happen.

For example, Wilo’s commercial application pumps come with multiple alarm warning codes that can help indicate if there is a system issue or pump issue. Error codes and alarms can even indicate if there is dirt in the systems or if the pump is running dry – eliminating any potential failure.

Taking the smart view Heating and hot water circulator pumps play a crucial role in many buildings and are particularly important in commercial applications where there’s a real need and drive to tighten up on energy and water usage. A clear way for installers to take action is to recommend swapping old, inefficient pumps for newer models with EC motor technology. In this way, they can play their part in the Net Zero movement, as well as save themselves from the headaches of installing, commissioning and maintaining static, ‘dumb’ products.

FERNOX LAUNCHES DEDICATED FILTER FOR HEAT PUMPS

F

ernox has extended its portfolio with the new TF1 Sigma HP Filter, a product which has been specifically designed to protect air and ground source heat pumps. The company has developed the new TF1 Sigma HP Filter to offer what it describes as “the best possible protection”. The company says that the filter’s shape allows for the efficient capture of system debris and the settlement of particles within the main body of the filter. The unit is manufactured from engineering-grade polymer.

Key to its performance is the utilisation of flow and filtration technology (patent pending), which allows the filter to capture all types of debris, including magnetite, hematite and scale – at high flow rates (up to 80 L/M) typical of heat pump installations.

The Fernox TF1 Sigma HP Filter is supplied with 22mm or 28mm full-bore valves as standard. The company says the design of these valves means that there is no restriction of flow through the filter assembly, ensuring the heat pump can maintain the required COP (Co-efficient of Performance).

the use of high integrity and high-quality components ensures that the Fernox TF1 Sigma HP Filter provides unparalleled performance

360˚ pipework Due to its double radial seal between the manifold and main filter body, the Fernox TF1 Sigma HP Filter is flexible. Installation is said to be quick and simple, enabling horizontal or vertical orientations or at any point around a full 360° pipework orientation.

Similar to the design of other products in the Fernox TF1 range, the TF1 Sigma HP Filter is engineered as a sealed unit without a lid for greater integrity and security, reducing any potential for leaks.

Greg Banham, UK & Ireland Sales Director at Fernox noted: “The TF1 Sigma HP Filter has been extensively tested,

proving it has the best Kv value of any available filter on the market. A combination of features including the unique, patent-pending filtration technology and the low-pressure loss from the carefully engineered flow paths mean that COP levels and heat pump efficiency can be maintained. Furthermore, the use of high integrity and high-quality components ensures that the Fernox TF1 Sigma HP Filter provides unparalleled performance.”

Domus Ventilation has expanded its HRXE range of Mechanical Ventilation with Heat Recovery (MVHR) units with the launch of HRXE-ZEUS. HRXE-ZEUS has been introduced to meet ventilation requirements for large residential properties, which require a more powerful system to deliver the airflow required to meet Building Regulations Part F. The HRXE-ZEUS MVHR system combines supply and extract ventilation in one system. Using an advanced heat exchanger, up to 95% of the heat typically lost in waste, stale air is efficiently recovered and used to temper the fresh air drawn into the building. The filtered, pre-warmed air is distributed to areas of the home such as living rooms and bedrooms, effectively meeting part of the heating load in energy efficient dwellings. The system features two independent fans which have full-speed control for background and boost ventilation rates.

HRXE-ZEUS comes with 100% thermal bypass which automatically activates when the air temperature reaches a pre-set level, allowing in cooler, fresh, filtered air without warming it through the heat exchanger. The design means there is no reduction in airflow when operating in bypass mode.

There are four models to choose from, available to meet different specifications and different on-site requirements, including opposite handed units and units with integral humidistat. HRXE-ZEUS accessories include an Anti-Vibration tray which isolates the unit from the wall to reduce any low levels of vibration induced noise, condensation drain kit and replacement filters. The filters are easily replaced via the front access panel.

Ergonomically designed for maximum comfort, freedom of movement and functionality, there’s over 80 different styles and 71 different sizes in the Snickers Workwear Trouser system. The men’s and women’s Trousers range includes full stretch slim fit styles plus street-smart regular and looser fits throughout the full LiteWork, FlexiWork, RUFFwork and AllroundWork trouser families.

With at least 16 pocket compartments integral to every pair complimented by a choice of eight different kneepads, Snickers Workwear trousers are designed to help to keep you comfortable, carry your essentials, and protect your knees and legs from debris and hazards in the workplace.

AQUALISA EVOLVE ELECTRIC SHOWER SERIES

RESIDEO BRAUKMANN FF60 TRIPLEX WATER FILTER

Aqualisa has introduced the eVOLVE range: a new line-up of electric showers. There is a choice of Arctic White, Space Grey or Midnight Black with a satin silver trim. Three power options (8.5kW, 9.5kW or 10.5kW) allow the selection of a model suited to a homeowner’s needs.

A-rated for energy efficiency, the units feature easy-to-use dials and deliver showers with no demand on the home’s stored hot water. Each model is equipped with an over temperature protection system, which the company says will ensure the water will always remain at the desired heat level and never exceed 50°C. A digital display shows the temperature at all times, and there is a low-pressure indicator to alert the user should the water pressure fall.

Designed to aid rainwater harvest and provide a continuous, sustainable supply of filtered, non-drinking water, Resideo has launched its Braukmann FF60 TRIPLEX water filter in the UK. It is suited for use in larger buildings such as schools, universities, and office buildings, where an efficient water supply can form part of an effective energy management system.

The Resideo Braukmann FF60 TRIPLEX water filter is made up of three different filter cartridges, in one housing, which can be replaced every six months. Capable of operating with a maximum water temperature of 45°C, the FF60 TRIPLEX water filter can be applied to rainwater treatment across a range of specifications.
