PROFESSIONAL HEATING & PLUMBING INSTALLER is a business journal for those involved in the installation, maintenance and repair of heating and plumbing systems. It is available to the trade at leading heating and plumbing merchants and specialist outlets throughout the UK.

A turbulent time

The end of the year is always a fitting time to look back on the previous 12 months* and 2022 has certainly been a tumultuous year.

Placing the domestic political situation to one side, the most significant story must be the Russian invasion of Ukraine, which began in February. The ramifications have been devasting for the country itself, with shockwaves felt right across the globe. In particular, oil, gas and energy prices rocketed – and with Europe now heading into winter significant levels of hardship will be felt by many.

With energy bills set to spiral, in September the UK government stepped-in to help consumers with an ‘energy price guarantee’ on the unit cost of energy, alongside other support. Whilst this will reduce the pain somewhat, bills will be significantly higher this year than last.

This energy crisis comes amidst on-going moves to address our commitments on fossil fuel reduction and throughout the year much has been said on how the sector needs to transition away from gas. To pursue this aim, in March, the Boiler Upgrade Scheme was introduced to incentivise the retrofitting of Heat Pumps. Three months later alterations to the Building Regulations came into effect which led new builds towards adopting the technology.

However, as previously reported in PHPI, interest in hydrogen as a replacement fuel for domestic boilers remains strong, with several manufacturers announcing ‘hydrogen-ready’ boilers during the year, while HVO and hybrid systems also remain part of the conversation.

Quite how all these factors will play out remains one for any owners of a crystal-ball, but whatever our future energy mix, it is clear that decisions on issues like energy security and fossil fuel reduction will have consequences for the UK’s heating sector.

With the year drawing to a close, perhaps one thing to wish for as the new year is welcomed is more certainty in the direction of our energy policy. This would help businesses to invest, installers to train and homeowners to be reassured about how their homes will be heated in the future… and perhaps most importantly, provide clarity on how much it will cost.

* this piece was compiled in late October, so to be transparent it is more of a 10-month review…

OVER A THIRD OF DRINKING WATER QUALITY FAILURES CAUSED BY HOME PLUMBING

The annual reports by the UK’s drinking water watchdog shows water supplies in England and Wales are of a high standard – with 99.97% and 99.98%, respectively, of samples collected and tested meeting the required levels.

However, the document also reveals more than 36% of water quality failures in homes in England, and 51% of failures in homes in Wales, stem from plumbing issues in customers’ own properties.

Julie Spinks, Director of WaterSafe, the UK register for approved contractors working with drinking water, said: “There are a number of things which can affect water quality in homes, or other buildings, such as incorrectly connected appliances likes dishwashers and washing machines, misconnections to waste pipes, poor quality taps and fittings and even contamination from home oil storage tanks.”

“Only plumbers and other specialist contractors with the right skills and knowledge to work safely with drinking water are allowed to join the WaterSafe register. This gives customers reassurance that they are using a competent and qualified professional to work on one of the most important supplies to their home.”

INDUSTRY LAUNCHES HELLO HYDROGEN CAMPAIGN

A number of organisations from across the UK energy industry have joined forces to launch a campaign to raise awareness of hydrogen gas for domestic heating and call on the Government to commit to a hydrogen future.

The ‘Hello Hydrogen’ Campaign sees gas distribution networks, boiler manufacturers and energy suppliers come together to raise households’ awareness on the low-carbon gas’s role in reducing CO2 emissions. Members of the group hope the information hub will teach people about new hydrogen-ready boilers and cookers that could be used to heat their homes in the future.

Commenting on the launch Campaign Director, Angela Needle said: “As people start to turn on their heating again, we think now is the perfect time to begin the conversation about how we will all heat our homes in the future. We want households to know that there will be numerous ways to warm up their radiators or cook their dinner and hydrogen could be the right choice for them.”

Campaign Chair, Victoria Billings of Worcester Bosch UK said: "The industry is coming together to build a hydrogen future that means household bills are no longer linked to global events. That's why we've launched the Hello Hydrogen campaign to make sure consumers are kept fully informed of the choices they have for the future of heating their homes.”

POLYPIPE INTRODUCES APPROVED ENGINEER PROGRAMME

Plastic piping and underfloor heating manufacturer Polypipe Building Products has launched a membership scheme for underfloor heating engineers.

Polypipe Underfloor Heating’s Approved Engineer (AE) programme launched in October and will give members access to expert advice and extra support on design and quotation – with direct contacts in the Polypipe team.

There will also be training opportunities covering all aspects of underfloor heating installation, from auto balancing manifolds to smart controls.

Dean Asher, Head of Technical and Customer Services at Polypipe Building Products, said: “With the impact of lockdowns over the past couple of year, now is a great time to reconnect with colleagues across the industry. It’s also a good time to stand out from the crowd and offer customers the assurance that you have the experience to do a great job. We believe that our Approved Engineer network will be very useful for installers and contractors as they enjoy the benefits of the specialist training our technical experts can offer.”

WORCESTER BOSCH RELAUNCHES ‘GREEN HEATING HEROES’ CAMPAIGN

Worcester Bosch has announced the relaunch of its consumer sustainability campaign, titled ‘Green Heating Heroes’, with the aim to help consumers think greener when it comes to their home heating in order to help save on bills and reduce their carbon footprint.

The company is looking to recruit installers across the UK to sign up to become ‘Green Heating Heroes’. With over 1,000 installers already part of the campaign, any who enlist will be part of a UK wide ensemble of installers committed to providing support and advice to those customers who are looking for sustainable ways to heat their homes.

VAN TOOL THEFT ON THE RISE

Tool theft has risen in the last 12 months with more than a third of van drivers falling victim – up from a quarter the year before, according to a study by Volkswagen Commercial Vehicles.

The study also found that when tools are stolen, it stops work for six days on average. It also notes that an increase in the number of van drivers leaving tools in their vehicles overnight, with three-quarters admitting to doing so compared to less than half in 2020, has created more opportunity for thieves. Around half of van drivers are taking extra precautions such as additional alarms, locks, and vehicle trackers. David Hanna, Head of Direct Sales at Volkswagen Commercial Vehicles, said: “Tool theft continues to be a huge problem and it’s worrying to see the problem spreading across the country. We’re shocked to see that cases have risen so much in the past year, as we know the impact on businesses and workers is massive.”

GLOW-WORM REVEALS MYSTERY TRIP DESTINATION FOR 2022

The destination of the Glow-worm Mystery Trip 2022 has been revealed as Mexico. Visiting the Riviera Maya region of Cancun in November, the 45 winners each received two tickets by exceeding personalised targets of Glow-worm installations via Club Energy. Spencer Clark, Commercial Director for UK & Ireland at Glow-worm said: “The Glow-worm Mystery Trip is our way of thanking our Club Energy installers for their ongoing loyalty. Now in its third year, the success of the Mystery Trip continues to grow, and each trip is better than the last, so we’re already excited to see what our winners make of this once in a lifetime trip to Mexico.”

LABOUR LEADER VISITS VAILLANT HQ

Labour leader, Sir Keir Starmer, has visited boiler and heat pump manufacturer, Vaillant, to see production of its low carbon technology and gain a clearer view of how government and industry can work in partnership to ensure the UK can successfully transition to low carbon technologies.

During the tour the Labour leader viewed the company’s new heat pump line, where UK manufacture of its aroTHERM plus air source heat pump is currently being ramped up with a view to being fully operational by the end of 2022.

Henrik Hansen, Managing Director at Vaillant, UK and Ireland, commented: “We are always willing to demonstrate what we as a company are doing to ensure UK homes can benefit from effective, low carbon heating. This transition is exciting, but it will require long-term thinking, planning and support from government to ensure it is a success. Solid investment in skills, policy and infrastructure must be built into this. There is no silver bullet to the decarbonisation of heat and in the future there will be several technologies available, which can be reviewed for best fit and then designed to work effectively in each individual property. As the first boiler manufacturer in the UK to produce both boilers and heat pumps, we welcomed the opportunity to present the progress being made and to discuss the commitment required to make low carbon heating a reality.”

WIN BACK THE COST OF YOUR GAS HEATING BILLS WITH ADEY

ADEY has launched a new competition this winter – a gesture of thanks that will see installers and their customers winning back the cost of their monthly gas heating bills.

With energy bills a major concern for households across the UK, ADEY has launched an initiative to reward installers, and their homeowners, for reducing gas energy bills by up to 7% through taking steps to make their central heating systems more efficient. Throughout October, November and December, any MagnaClean filter installed in a home and warranty registered in ADEY ProClub, will be entered into a prize draw to win up to £1,500.

“We know for many people that the ongoing energy crisis, which has seen bills soar, is extremely worrying,” commented ADEY Marketing Director, Claire Miller. “There’s a huge opportunity for installers to talk to their customers about the importance of looking after their heating systems and encouraging them to fit a MagnaClean, with the added benefit of being entered into the prize draw on top of that.”

NAVIEN’S OIL BOILERS ARE HVO READY

Navien’s LCB700 Blue Flame boilers are all compatible with Hydrotreated Vegetable Oil (HVO), in line with the government’s decarbonisation targets.

HVO is a fossil free fuel, sustainably produced, renewable paraffin that comes from used cooking oil and vegetable oil processing waste.

Assessing the benefits of Hydrotreated Vegetable Oil, Sean Keleher, National Technical Manager at Navien, said: “With a lot of people – especially those in rural areas – still reliant on oil-fired boilers, it’s vital for manufacturers and industry groups to join together and embrace HVO as a more environmental fuel. HVO is safer to handle due to its lower flashpoint, plus it’s biodegradable.”

INBRIEF...

Innovation charity NESTA is launching a new step-by-step online tool to help guide people through quickly and easily turning down their combi boiler flow temperature. The tool is supported by campaign partners Which?, Energy UK, EDF, E.ON Next and Octopus Energy. The charity says, if 10 million UK households with combi boilers reset their flow temperature to 60°C or below, this would cut £1billion from energy bills and save 1.7million tonnes of carbon emissions.

Consumer champion, Which?, has awarded WORCESTER BOSCH its Best Buy endorsement for a thirteenth time for its gas combi boiler range. The annual Which? report revealed that Worcester Bosch is the most reliable boiler brand on the market according to its in-depth survey based on customer satisfaction, product quality and after-care service. Worcester Bosch received 5 star-tier ratings across three categories as its gas boiler received an 84% recommendation rating.

Free online tech talk videos offering engineers and system designers access to important information on how to maximise the performance of heating and cooling systems have been launched by SPIROTECH. The online videos are ‘as live’ recordings of the company’s latest SpiroExpert sessions that provide technical information, common challenge solutions and expert insight on the latest issues and trends in the industry. The subjects currently available include Deaeration & Degassing and VDI 2035.

Heat pump installers will now be able to offer homeowners a range of flexible payment options thanks to a new partnership between Daikin and back-office support app, HIBER. Under the new partnership, Daikin installers will be able to extend the range of payments options their customers can select, including finance, through use of the hiber platform.

2023

a place within government.

The landscape has changed significantly and its principally down to the cost of living and the cost of energy which has placed a significant burden on householders across the country. To make products now is costing significantly more than ever before as manufacturers have higher energy costs to carry, and raw material increases which then means it gets passed onto the sale price of goods.

The price freeze put in place by Liz Truss in October seemed to be very welcome by householders however, the price of our gas and electricity costs will be significantly higher than last year. We are very much hoping for a mild winter in the hopes to cut down costs on heating and hot water.

2025

not just hydrogen ready boilers.

In addition, we will see the Building Regulations, as changed in 2022, start to embed in and for new build properties built to these regulations, that would mean a 31% reduction in CO² levels, compared to a house built to the 2018 regulations.

It will still be possible to install a gas fired boiler in these situations, but it must

to make it nearly impossible to fit anything other than a heat pump into an individual property.”

Martyn Bridges,Director of Technical Services at WorcesterBosch, discusses what liesahead for the heatingindustry in 2023following a year ofpolitical change and uncertainty.

be augmented with either increased insulation or very likely with solar PV or wastewater recovery. Solar PV is an incredible technology, and it is to a degree unforgiveable that brand new properties don’t get installed with an array of panels on the roof to capture this free source of energy.

Government and industry

The government is in some turmoil with what is now three Prime Ministers having been appointed in 2022 which won’t bode well for the continuity and stability of energy policy. We have had numerous ministers over the last 20 years, and nobody seems to remain in position long enough to create policies which we can all get behind and support.

MP Chris Skidmore has been appointed to investigate the progress being made on net zero, and a consultation has been put into place to hopefully aid with this. The sentiments within the consultation seem to be heavily in tune with costs to the consumer and costs and bureaucracy to businesses, presumably with a view to removing or at least reducing these burdens.

Recommendations from the MP have been requested to be handed to the Prime Minister by the end of the year. These recommendations will, hopefully, help to share the outcomes from net zero and how as an industry we can move towards meeting government targets. Of course, with now a change in leadership from Truss, these timelines and focuses may change in regard to future technology and net zero ambitions.

Market growth

From a market perspective I think we will still see steady growth of heat pump sales. The Boiler Upgrade Scheme was welcomed by homeowners but was not as successful as we had initially hoped. It seems unlikely, however that we will hit the 600,000 annual installation figure that was proposed by Boris Johnson some 18 months ago.

However, we will see an organic rise in heat pump installations and will probably see a significant rise when the Building Regulations of 2025 change to make it nearly impossible to fit anything other than a heat pump

into an individual property.

On the flip side, we are likely to still see boiler sales of around 1.5-1.6 million, like we do every year, and a growing interest in other low carbon technologies, including solar PV and hybrid systems.

In summary, it’s still a bit of a waiting game and we’re still unsure of how 2023 will pan out from a legislative perspective. I feel the market is unlikely to change dramatically to previous years, but it will be interesting to see where government and industry updates will take us.

RWC

RELIANCE VALVES MULTISAFE LEAK DETECTION SYSTEM

In April we looked at the Reliance Valves MultiSafe Leak Detection System, designed to constantly monitor water usage to safeguard plumbing and heating systems and identify potential failures that can lead to leaks. The system works by identifying leaks early to prevent water damage. It sends an alert when a leak is detected, and automatically shuts off the water supply. The system also monitors water usage and patterns, identifying potential areas for conservation, and can be connected with multiple devices on the same WiFi network to centrally control several devices in large buildings or apartments. It can be controlled using RWC’s free app, where instant alerts can be set up, real-time insights can be viewed, and settings can be adjusted using home and away modes.

VIESSMANN MONOBLOC ASHPS

SALAMANDER PUMPS TAPBOOST PUMP

Earlier this year, Salamander Pumps announced the launch of a brand-new pump, TapBoost, designed to offer a solution to boost the performance of a single tap or outlet. Designed to add up to six litres of additional flow, TapBoost provides a solution for when a slow flowing kitchen tap means the kettle takes an age to fill, a trickling bathroom tap is making washing hands difficult, or if a customer is tired of waiting for the toilet cistern to refill.

The pump can be fitted at multiple locations around the house, including bathroom and kitchen sinks, bath taps, garden taps, toilet cisterns, dishwashers, washing machines and showers. It has been designed to be quiet, has an inline design with brass fittings and it can be installed in either a mains-fed or a gravity-fed system.

In the spring, Viessmann announced the launch of two new monobloc air source heat pumps, the Vitocal 150-A and Vitocal 151-A – each available with outputs of 10, 13 and 16kW. Both the wall-mounted Vitocal 150-A and the floor-standing Vitocal 151-A have a maximum flow temperature of 70°C (at an outside temperature down to -10°C), meaning that in most cases they can use existing radiators and do not require under-floor heating. The new products use the same control platform as Viessmann’s boilers, so that they are compatible with the rest of the company’s product range, and both integrate previously separate system elements in the indoor unit (IDU), reducing installation time. Both models also feature Viessmann’s ‘Super Silent Design’. The Vitocal 151-A has an integral, 190-litre DHW cylinder.

DRAYTON AUTO-BALANCING TRV

In the middle of the year Drayton launched its new auto-balancing TRV technology, available for two of its most popular ranges – TRV4 and RT414. The chrome thermostatic radiator valve has been designed for UK domestic applications and have the same dimensions as all GB pattern valve bodies found in UK systems, meaning no pipework needs to be changed when retrofitting. Once installed and set, the auto-balancing valves will ensure that radiators permanently receive the correct flow rate regardless of other TRVs opening and closing or changes to the system.

For existing radiators, where installers are unsure of the heat output, they can use the new handy valve setting calculator on Drayton’s website to determine the correct setting for each auto-balancing TRV they are installing on the system.

WILO WILO-ISAR BOOST5 COMPACT WATER BOOSTING SYSTEM

Featured in October was Wilo UK’s new compact water boosting system. The new Wilo-Isar BOOST5 is a compact, plug and play solution that uses multistage, self-priming and automatic pressure-boosting technology to offer a solution to combat fluctuating or insufficient water pressure. The system has been designed to guarantee constant pressure for domestic water supply in large domestic settings, as well as smaller non-residential amenities, businesses and small sports facilities. It has a plug-in design, offering easy installation, and there is also an LED display and button controls to make it simple to operate for the end user. The system automatically adjusts its speed to the requirements within the property, only providing an extra water boost when required.

MAKITA

KT001G KETTLE

Earlier in the year Makita introduced several new products to its XGT 40VMax range – including the DK0014G and DK0172G combo kits, which both feature two of the company’s most popular professional cordless power tools in a convenient storage solution. However, the item that stood out for us was the KT001G Kettle, just in case you need a brew. It can be powered by Makita’s XGT 40VMax batteries or the PDC1200 portable power pack to boil water wherever you are on site. It is equipped with an anti-spill lock button to prevent accidental spills and it stops boiling automatically when the kettle or power supply stand is lifted to ensure safety.

And, thanks to the carry handle on the power supply stand, the KT001G should be easy to transport around site.

How to save energy on home heating is high on many customers’ agendas, especially as we move headlong into the colder months. In a recent survey by Resideo, a fifth of those questioned said they would reach out to a heating professional for recommendations and advice on where savings can be made. As customer budgets will vary, Martin Wilson, Sales Director at Resideo, looks at some of the options that can be suggested and the possible savings in both the short and longer term.

EXTRA EFFICIENCIES

‘very concerned’ about rising energy costs.1 However, just under half (43%) said they would be keen to invest in the latest heating controls if it meant they could save money in the long term. This figure increased to 70% amongst 25 – 34-year-olds.

It is inevitable that some homeowners will be in the position where they need to replace an aged boiler that can’t be repaired. Others may just be keen to know where they can upgrade parts of an existing system to get the most efficiency. In both cases, getting the best return for their investment will be key.

Quick checks

A double check that an existing control is set correctly, and that the customer knows how to set it to best effect can be a simple, quick check. Indeed, a common misconception still seems to be that turning the thermostat up will make the home warmer more quickly. This is more likely to be make the boiler work that bit harder to

reach a higher temperature, inadvertently burning through more fuel rather than helping the room to warm up more quickly. It may be an adage but turning the thermostat down one degree can actually help save around 10% too2

Efficiency returns

As installers know, an effective system is only as good as the sum of its parts and adding elements such as thermostats or upgraded radiator valves can have a tangible impact on efficiency. In fact, it is still expected that millions of properties across the UK have inadequate controls for their heating system. The result being that the

boiler is either on or off, continuing to pump out heat long after the room reaches the right temperature. Where people can or need to change their boiler, their controls or even the radiator valves, it is possible to recommend a range of options to suit differing budgets and address the issues that could be affecting how the system runs.

To equip installers with handy stats that can help customers understand the difference various options can deliver, Resideo has worked with BEAMA to typify how switching controls can help, based on an older mechanical thermostat being in place3.

Switching to digital

Where a property has an older mechanical thermostat in place, replacing it with a newer, digital version can make a significant difference to a customers’ energy bills. For example, based on current energy prices, simply swapping an old mechanical thermostat for a digital, load compensating thermostat can save up to £181 per year.2

it is possible to recommend a range of options to suit differing budgets and address the issues that could be affecting how the system runs.

Go further, and upgrade a mechanical thermostat to an OpenTherm (load compensating) thermostat, such as the Honeywell Home T6R or T4M, could see these savings increase to up to £218 a year.3

TRV upgrades

I’m sure many homeowners aren’t fully aware of the impact radiator valves can have on how effective a heating system is too. Swapping manual radiator valves for thermostatic radiator valves (TRVs) ensures that each room is maintained at a comfortable temperature and can be adapted to suit usage, helping avoid energy wasted by overheating rooms that are not used frequently, for instance. This switch could save your customer £327 a year3, so is one not to be overlooked.

A full review

There also may be customers who will want to take the plunge and completely upgrade their heating controls. Replacing manual radiator valves and a mechanical thermostat with electronic TRVs and a modulating, OpenTherm zoning thermostat solution, such as the Honeywell Home evohome, customers could be looking at savings of over £585 a year.3

Indeed, an advanced thermostat that can navigate temperature fluctuations; monitoring outside weather temperatures

and communicating with the heating system to adjust the temperature within the property, ensures that energy is being used most efficiently by turning on up the system only when heat is required. For example, the smart weather feature on the Honeywell Home evohome system offers improved zone comfort control and energy consumption, based on outside temperature, room temperature and a unique feature that learns the heat losses in each room.

Equally, smart zoning capabilities use radiator controllers to wirelessly measure and control temperatures for up to 12 zones individually. For homes with this in place, the ability to set and or alter the temperature of a room from the control or via the app on a smart device means that rooms can be heated individually

according to which are being used at the time and for what purpose. The kitchen, for instance, could be at 18 degrees where the lounge at a slightly higher 20 or 21 degrees.

Using resources

This year’s heating season feels like it will be busier than ever due to a mix of those wanting to get the most out of their existing boiler plus those considering replacing and updating what they already have.

To support installers during this busy heating season, Resideo’s Winter Heroes campaign has been designed to help provide installers with useful information and stats to when making recommendations to customers who are looking to make a change to get the very best out of their heating.

HEAT PUMP CURIOUS?

With many in the sector considering Heat Pumps, PHPI spoke with Neil Hopkinson, National Heating Sales Distribution Manager from HVAC specialist LG to find out more about the company’s latest Therma V R32 Monobloc S air source heat pump.

Today’s Air to Water Heat Pump (AWHP) systems – monoblocs or splits – are hugely energy efficient when you compare them to traditional fossil fuel driven heating systems. The highest efficiency boiler you can buy is something like 95% efficient.

An AWHP like LG’s new Monobloc has a seasonal coefficient of performance of up to 4.67 and an A+++ rating – and presents a variety of energy-saving options for a home’s heating and hot water system. By

energy from external air makes them consume less energy than conventional heating systems. And they can operate successfully at low temperatures – the LG Therma V range has 100% capacity at temperatures as low as -7°C – and it’s very rare for temperatures in the UK to go that low even for a day each year.

The terms ‘Split’ and ‘Monobloc’ refer to

components – apart from the hot water cylinder which is installed inside the property – located inside a heat pump unit situated outside the home. Because a monobloc does not require someone with F Gas qualifications to get involved in the use of refrigerants, they are an excellent additional string to the bow of most professional heating installers who after attending a relevant training course will be well placed to join the growing band of installers that will be required to swell the numbers of people capable of installing these excellent heating systems here in our home market.

A Split heat pump unit has both an outside unit which incorporates the heat exchanger and refrigerant and an internal unit which sits inside the property, usually in a utility or boiler room.

Most homes in the UK are ideal for a Monobloc air to water heat pump but some will require upgrades to their level of insulation. A Split system is an option generally for more complex installations and it can be installed up to 50m away from the home, which gives far more installation flexibility.

QDo installers need an F-gas qualification to fit ASHPs?

Installers only need an F-Gas qualification if they are installing equipment that requires them to work with refrigerants. This is the

QWhat is the difference between a Monobloc and a split system? And how does a monobloc work?

joy of installing monobloc systems where the system comes ready primed with the refrigerant – in the case of the LG Therma V Monobloc it’s R32, which has a low Global Warming Potential of just 675 – 70% lower than R410A which was widely used in recent years. With monoblocs like the LG one, the only pipework to install is the water pipe between the external unit and the internal hot water tank.

The original LG Therma V Monobloc has already seen enormous success in the UK marketplace as heat pump sales in 2021 trebled over sales in the previous year. But this new ‘S’ version is set to make unparalleled sales figures in 2022 as more and more housebuilders and developers, local authorities and social housing providers move to use renewable options in their new build homes and begin the process of replacing older and inefficient gas boilers with an option that future proofs their existing homes in the years ahead.

This new model combines the indoor and outdoor features in one module. Hydronic components like the improved plate heat exchanger, the expansion tank, water pump, flow sensor, pressure sensor, air vent valve and safety valve are all built in – inside the outdoor unit – pre-installed and ready to run. And the R32 Monobloc ‘S’ provides excellent heating performance especially at low ambient temperatures whilst lowering its carbon emissions even more with the use of R32.

The design and technology in this new unit sees built in water flow and pressure sensors to monitor the water circuit in real time, advanced water pump control, enhanced second circuit logic, energy monitoring of estimated power consumption via the remote controller and advanced control for the domestic hot water recirculation pump.

Installers will love the new Monobloc ‘S’ – the all-in-one concept and reduced weight of the unit makes for easier and quicker installations. The new version requires lower amounts of refrigerant compared to the existing model – 16.7% less in fact – reducing emissions and lessening its environmental impact still further. The new version features LG’s R1 Compressor technology which offers advanced efficiency, reliability and operational range due in part to the enhanced tilting motion of the scroll. It offers enhanced operational range – up to 135Hz, a shaft-through structure and support at both ends of the shaft which ensures higher durability and offers bottom compression and simple structure that offers lower noise and vibration, less weight and superior reliability.

Within the outdoor unit the new version of the LG Monobloc offers a new compressor noise shield, a new Black Fin coated heat exchanger, a new water flow

sensor and a new water pressure sensor. The unit comes with a Seasonal Coefficient of Performance of up to 4.67 (Average climate/Low temperature application) and a A+++ rating. The COP rises to 4.9 (Outdoor air 7°C/Leaving water temperature 35°C) and can deliver leaving water temperature of 65°C if required.

This is a bit of a red herring today. ASHPs are in general very quiet and do not cause any issues for owners or their neighbours. The original LG Therma V Monobloc version was extremely quiet, but the new ‘S’ version is even quieter and up to 9kW units can be installed at the minimum of four metres away, and up to 16kW units up to five metres away from neighbouring houses complying with international noise regulations.

LG equipment is justly renowned in the industry for its controllers and the new Monobloc ‘S’ is equipped with a new advanced remote controller which supports a number of functions.

It comes with a premium design 4.3-inch colour LCD monitor, user friendly interface that uses simple graphic, icon and text controls, easy schedule and installer settings and energy monitoring without meter interface to provide estimated power consumption figures. It is possible to monitor not only the temperature of the water circuit but also the flow rate and the pressure. This information provides installers with more reliable information for installation and maintenance.

Danfoss has introduced a new range of Electronic Room Controls.

Danfoss has introduced a new range of energy-saving Electronic Room Controls (ERC) – the first to be co-created with installers.

From its industry-standard backplate to the multiple cable access design and intuitive display wrapped in a full white exterior, the new ERC collection is designed for ease – from selection and installation to programming and everyday use. Additionally, Danfoss has extended the warranty on the new range from two to five years and all models are 100% Boiler Plus compliant.

Streamlined range

Danfoss has streamlined the range to make choosing the right product for the job easier for installers. Models now include the TS710 and FP720 time switch and programmer respectively; the TP5001 range of programmable room thermostats; the RET2001 digital room thermostat range; and the RET1001M dial room thermostat.

The new ERCs have a

Danfoss listened to installers and used their feedback to develop an ERC range that is fast and hassle-free to fit and even more user-friendly, said Gareth Ash, Marketing Communications Manager at Danfoss. “We’ve involved installers in every step of the design phase,” he explained. “We believe this approach shows the importance Danfoss places on continuous dialogue with customers so we can reflect their needs in our products.”

read PR to avoid confusion.

In addition, the previous 365-day service interval has been updated in line with regulations to a minimum of 400 days.

New look

As part of the redesign Danfoss ERCs have also been given a new look and more user-friendly features. A full white design, including the backplate, is complemented by new easy to read displays, plus a larger dial on RET models. The RET and TP ranges also have clearer detailing, while the FP720 now includes LEDs and clearer labelling of functions.

According to Gareth Ash the new installer-approved Danfoss ERC range offers a value proposition that is not only quick and simple to fit in new and retrofit projects but also raises the bar on energy saving.

Summing up, he says: “Research by the University of Salford shows that replacing a standard room thermostat with one that controls the boiler using load or weather compensation can deliver savings of 10% whenever the heating is on. So, with models that offer OpenTherm and on/off load compensation the new, easy to install Danfoss ERCs are the obvious choice for efficiency too.”

To help reduce the cost of heating in difficult times, Jon Tedstone, Head of Sales and Marketing, ESi, outlines how installers can help select the right controls for the right end-users.

Selection day

From sophisticated users who want the latest wifi controlled options, to elderly or vulnerable people who need the simplest of controls to cope with their heating system – it’s vital that there’s a full range of complexity available in today’s heating controls marketplace. And ESi is taking a lead in this forward-thinking

to which heating controls to include in a new build heating installation or in a heating system replacement project is more important than ever. But it’s not always straightforward, with a wealth of options available and a range of combinations of components that can enable homeowners to be in control of the heating in their homes.

But it’s vital that the controls installed meet the requirements and on occasions the limitations of the potential users. There is no point installing the latest wifi or blue tooth connected controls if the homeowner or tenant is elderly or vulnerable and unable to fathom out how to use the latest smart controls now available. If they need a straightforward dial control, that is what you should install.

Minimise consumption

Clever use of controls can help minimise energy consumption by ensuring each room is at the right temperature for comfort, whilst avoiding overheating. This will keep your customer’s home cosy and cut their energy bills which is, at the end of the day, what they want from you.

Installers are still the key decision makers when it comes to selecting heating controls – most of their customers will rely on them to offer the best solution for them and it will help if installers can explain the controls in reasonable detail to make them aware of why they are installing the controls they have selected, even if in broad terms relating to the energy savings available and the environmental benefits of the controls chosen.

OpenTherm

As well as offering Boiler Plus compliant units, ESi is one of the leading members of the OpenTherm Association here in the UK, offering access to the OpenTherm protocol. OpenTherm is a non-manufacturer dependent system of communication between modulating HVAC appliances and room thermostats. Quite simply, it consists of a communication protocol and an interface specification.

More and more appliance manufacturers are bringing modulating central heating systems onto the market – traditional boilers and renewable options including many heat pumps. These appliances offer better efficiency and reduced environmental effects. However, to operate these appliances, a communication protocol between the appliance and the controller is required. It involves the addition of a

small bit of software only available to OpenTherm Association members.

OpenTherm is a communications protocol that allows modulating heating appliances to communicate directly with the heating controls within the property. By having constant communications between the ‘thermostat’ and the ‘boiler’, the heating controls can accurately control the appliances heating output, ensuring the correct amount of heat is given to the heating system at the correct time. In terms of OpenTherm gas condensing boilers, this leads to significant energy savings by keeping condensing boilers in condensing mode for much longer durations.

OpenTherm allows 3rd party control manufacturers to create a wide range of simple control solutions for boilers. Over complicated controls can lead to energy wastage, but simplified OpenTherm

knowledge that whatever OpenTherm control they choose, the boiler would always run at its most efficient point.

OpenTherm allows remote boiler diagnosis too, which can lead to service intervals being extended, reduced downtime and ultimately money savings. Whilst the amount that can be saved on energy costs by using OpenTherm varies between installations, 10% is a reasonable estimate, up to 15% is not uncommon. And with gas prices at their current levels, that’s not a saving to be lightly ignored.

The beauty of OpenTherm is it can be applied not just to modulation condensing gas boilers, but to any heating and hot water system that uses the OpenTherm protocol. So, an OpenTherm gas boiler and OpenTherm control fitted right now, could be easily added to an OpenTherm Heat Pump and OpenTherm MVHR system in the future. OpenTherm can easily be changed and adapted.

ESi is just one of the companies signed up to the OpenTherm Association, agreeing to work with it to introduce a wider acceptance of OpenTherm as a standard in the UK. Manufacturers of boilers and controls that have already evaluated the OpenTherm protocol’s compatibility with their systems include major companies in Europe with an influence in the UK – wanting to see the acceptance of the OpenTherm protocol here in the UK marketplace.

Recognising the common sense in developing a common use ‘Open’ system here in the UK, the protocol importantly, also has the support of industry bodies HHIC and BEAMA who are committed to supporting OpenTherm’s wider introduction here.

Programmable room thermostat

For those keen to experience the latest in heating controls technology, ESi has launched its new, top of the range, 6 Series WiFi Programmable Room Thermostat, offering the latest in heating control for homes and commercial premises here in the UK.Fully OpenTherm compatible, this new range of controls allows full control via the room thermostat or via a mobile phone or tablet, with a range of features to impress even the most demanding specifier, installer or homeowner.

It includes Optimum Start/Stop, Domestic Hot Water (DHW) setpoint, Hot Water time and temperature control when working in conjunction with a wireless cylinder thermostat, full 7 day, 5/2 day or 24 hour programming options, a boost facility, a helpful Holiday Mode and is an ERP Class 5 Product. The new controls are available in white or grey.

PUTS USERS IN CONTROL

f used correctly, IoT technology gives greater control of thermostats and room sensors to ensure heating systems run more efficiently, sustainably – and just as crucially during these challenging economic times – more cost-effectively. Aligned with Boiler Plus regulations, Vokèra is fully-focused on developing heating systems that integrate more effectively with IoT technology.

More control

Next level integration of modulating controls as per Boiler Plus regulations in the form of load and weather compensation improves temperature flows and allows boilers to run more efficiently. Load compensation controls, for example, modulate the flow temperature from the boiler based on the actual room temperature. This requires the thermostat and boiler to ‘speak’ the same language, a function that is enabled by communications protocol – Vokèra uses OpenTherm.

A similar principle is at the heart of weather compensation controls that use the outside temperature to modulate a boiler’s temperature flow. A lower flow temperature (at 55°C and below) supports better efficiency, as the boiler will be condensing, and therefore recovering latent heat from the products of combustion that would be lost at higher flow temperatures.

The increase in global fuel prices means many UK households will be minded to ration their heating this winter. Monitoring the usage of heating systems couldn’t be easier thanks to Internet of Things (IoT) technology. Neil Mattock, Marketing Director and Head of Training at Vokèra by Riello, explains how IoT offers more than mere ‘switch on/switch off’ capability.

As well as allowing property owners to reset their heating system remotely, in the event of a system error code or interruption in the gas supply, for example, digital interconnection enables installers off-site access – if permitted by the customer – to diagnose issues in a significantly more convenient and effective manner for both parties.

Intelligent connection

Devising a method of connecting a boiler directly to the internet without interfering with the control is crucial to advancing the heating/digital ecosystem relationship. It’s a development that Vokèra is progressing through its software-based Hi, Comfort platform, which features next generation boilers and smart thermostats. It includes the evolvement of the Hi, Comfort K100 smart key, a superbly simple plug-in innovation that permits remote control of boilers via the specially devised Hi, Comfort app.

This increases boiler management efficiency in relation to issues such as running time monitoring, geofencing and remote setting of DHW temperature. Beneficial for checking the operating parameters of individual household boilers, the connected technology afforded by the Hi, Comfort K100 smart key could prove very useful when managing an estate of systems within a social housing block, for instance.

Future proofed

In future, this type of digital ecosystem could be adapted to manage multiple technologies as heating systems become more hybrid. Therefore, the technology involved in linking a heat pump to a boiler and solar panels could be controlled by a single digital platform working in an intelligent way to maximise the system’s efficiency. Such control could enable elements of the system to be programmed to work independently of each other or

incapable of managing a heating system or becomes a less attractive economic option. On such occasions, the system could be remotely managed via the internet to switch to a boiler-only or bivalent operation. But how do we start linking these different technologies together in a way that is easy for the end user to understand? The benefits for customers in the form of preventative maintenance are there for the asking if a heating system’s programme offers clear, identifiable responses. Think about how a warning light indicates when a car component is under stress. It usually means the vehicle remains driveable but that the driver should seek service assistance. A similar function for boilers could spare homeowners an unnecessarily costly repair bill.

Fully connected

functionality and sustainability. System efficiency is core to every manufacturer’s business model. At Vokèra, we’re achieving this by recognising the need to produce an interface that allows the user to manage their heating in a simple and efficient manner with minimal adjustment but also provide a conduit between heating appliance, user and service organisation or manufacturer.

Vokèra acknowledges the need for an interface that allows the user to manage their heating in a simple and efficient manner with minimal adjustment but also provides a conduit between heating appliance, user and service organisation or manufacturer. The IoT has a significant role to play in facilitating such an outcome; a smart process that will ultimately lead to greater fuel efficiency and a more sustainable built environment.

SUIT UP FOR WORKING IN WINTER

When the weather takes a turn for the worse, it’s time for you to make sure you suit up with properly designed, sustainable working clothes that have got what it takes to keep you warm and dry – whatever you’re doing on site – inside or out.

This winter, workwear choices will be as much influenced by sustainability as they are for comfort, practicality and protection. Many tradesmen and women are buying better-quality garments that will last longer because they incorporate recycled fibres in the fabric technology which reduces environmental waste.

In fact, it’s becoming more widely recognised that cheap, throwaway working clothes are contributing to our environmental concerns while garments made from sustainable ‘Preferred Fibres’ deliver high levels of durability and comfort. They’re good value, hard-wearing products with a long product lifetime which is key to reducing waste.

Dress for the weather

If you’re freezing cold, you’re not going to be working as efficiently and comfortably

as you could. That’s why wearing layers is the best way to regulate your body temperature when you’re working in unpredictable or generally inclement weather conditions. A 3-layer workwear system – Base-layers, Mid-layers and Outer-layers – will keep you warm and comfortable by transporting moisture away from your skin, insulating your body, and protecting you from cold, wet and windy weather. Whether it’s hot or cold, the solution to effective layering is making sure you stay dry, even when you’re working up a sweat and the best way to do just that is through the layer that’s closest to your skin – the Base-layer.

Base-layers

These first-layer undergarments, including socks are vital for staying dry and ventilated and the types you wear should ‘wick’ – transport – moisture away from your skin. The range of Base-layer clothes from Snickers Workwear have seamless comfort and a great ergonomic fit, but different garments fabrics such as those with ‘37.5 technology’ provide different levels of ventilation and warmth depending on how active you are while working and the weather conditions you’re working in.

For instance, during the colder months of the year, Merino wool is a natural and durable Base-layer choice. While it can absorb around 5% of its own weight in moisture, this type of wool has the added benefit of being naturally odour resistant –and it’s environmentally friendly.

Mid-layers

If your job involves moving back and forth, indoors and outside, or you find yourself constantly switching back and forth between physical and stationary tasks in colder conditions, then it’s worth paying particular attention to your choice of Mid-layer clothing.

wearing layers is the best way to regulate your body temperature when you’re working in unpredictable or generally inclement weather conditions.

Peter Dumigan, Managing Director of the Hultafors Group UK, which owns Snickers Workwear, provides a few tips for working during cold weather.

Your second – middle – layer is designed for warmth and insulation and to compliment your base-layers. If it’s ergonomically designed for a body-mapping fit, it should trap your body heat in a pocket of warm air around you. That means your Mid-layer needs to fit well, without being too tight or loose. Ideally, it will be made from a knitted, quilted, fleece, or microfleece materials that provide an airy yet comfortable enclosure.

However, if your work is physically demanding, ventilating your body is vital and this is where garment functionality is absolutely vital. You’ll need ‘Hybrid’ garments that provide insulation combined with ventilation and multiple functionality features like Snickers Workwear’s fleeces, gilets and lightweight jackets which are made from more environmentally friendly fabrics such as recycled polyester.

Outer-layers

If you have to work outside in cold, wet, or windy weather for long periods, work will get even harder. That’s when you’ll want to protect yourself from the elements with your own protective shell – the third weatherproof Outer-layer.

Your third layer needs to deliver effective wind and water protection to keep you warm, dry and to ensure the effectiveness of the two inner layers. And as with both Base- and Mid-layers, you’ll want to avoid getting too warm – so insultation combined with ventilation features in your outer garments are absolutely vital.

That means that you need jackets designed to be durable and weatherproof which complement the garments’ overall technical functionality. Snickers Workwear’s Work Jackets are built to be weatherproof enough to keep the elements at bay, and durable enough to withstand the wear and tear of hard day’s work but still delivering the level of breathability and ventilation you need for a comfortable and effective day at work.

Snickers Workwear’s layering system includes body-mapping Underwear, Jackets, Tops, Trousers and Accessories designed to work together for sustainable working comfort and protection wherever

Weatherproofed workwear

“How wet are you likely to get on site?”

Peter says... Your answer will help you choose the right type of rainwear to wear. What does the weather forecast say? Is there a risk of heavy rain, showers or drizzle? Will your work be low-intensity or more active?

Finally, how long will you be exposed to the wet weather – minutes or hours? Hence, longer shifts will put more demands on your working clothes and the waterproof technology used in the garments. That’s why you need to consider whether you should be wearing waterproof or water-repellent clothing.

So, for longer exposure or, if you need 100% protection on site in the rain, look for our GORE-TEX jackets. These highly technical garments are extremely durable with a membrane that has over 1.4 billion pores per square cm. They’re waterproof to keep you dry, windproof to keep you warm, and breathable to keep you comfortable all day long.

For quick and reliable protection when it’s raining or if your work is less active, choose our PU garments which, along

with our other rainwear clothing have EN 343 certification for Protection against Foul Weather. This accreditation validates the garment’s performance in the rain through independent testing.

Also, don’t forget about ventilation. Your clothes’ breathability is as crucial for your comfort as the outer-layer protection against water, especially when you’re working hard. Clothes with good climate control that transports sweat away from the skin.

So, make it a habit of checking the breathability features of the garments you buy. Breathability comes in two ways. Either the breathability of the fabric itself, such as our 37.5 technology sports fabric, or built-in ventilation functionality such as zippers or meshed fabric areas at the sides and back of the garments.

Finally, whatever the winter weather may do to dampen your spirits, as far as your work clothes are concerned, by making a conscious buying choice in the right workwear, you can work effectively and comfortably all day long – and with an eye on reducing your own carbon footprint.

QThe new battery, the 40VMax XGT 8.0Ah (BL4080F), has around 288 watt-hours of energy. How has this been achieved and what does it mean for an installer?

This represents our largest capacity battery to date, which has been achieved by adding larger capacity cells to the battery pack. At 288Wh this means the user can work harder for longer on heavy duty and high-drain applications, with reduced down time.

The battery uses lithium-ion technology, which we have refined over the years so that it can reliably provide the power needed for our cordless power tools.

Lithium-ion is more energy dense, and therefore can provide professionals with greater power to work for longer without the need to recharge.

POWER BOOST

There is a slight increase in weight for the 8Ah XGT battery at 1.9kg, against the 5Ah which weighs in at 1.3kg.

QThe new battery is rated as IPX4. What does this mean and how has it been achieved?

The BL4080F is IPX4 rated with a triple layer waterproofing, which means it is splash and shower proof, ideal for work outside in unpredictable weather or on pipework and plumbing systems.

The battery is housed in shock absorbing material with a heavy-duty and durable outer cell casing that is also dust-resistant, making it suitable for any job site condition.

Makita has recently launched a new battery for its XGT products promising longer run-time and improved performance. We spoke with Martin Dunn, Senior Training Officer at Makita, to find out more about the new power unit.

The new 8.0Ah XGT battery can be charged on the existing DC40RA ‘XGT’ Rapid Battery Charger and the DC40RB ‘XGT’ Twin Port Rapid Battery Charger. The DC40RB XGT Twin Port Rapid Battery

QAs the battery offers more performance, is their also an increase in its weight?

QCan the battery be charged from an existing Makita charger, or would a new charger be required?

Charger can charge two lithium-ion 40VMax XGT batteries simultaneously, saving time so that the battery can spend more time working and less time charging, providing professionals with greater productivity. For further convenience, these chargers can also be used in conjunction with an ADP10 Adaptor, to charge our 18V LXT batteries, offering professionals even more flexibility on site to switch between tools and tasks.

50th Anniversary

Makita is celebrating 50 years in the UK in 2022. Kevin Brannigan, Marketing Manager, Makita UK, tells us more.

When used with either the DC40RA or the DC40RB, the 8.0Ah battery will take approximately 76 minutes to reach a full charge, or 60 minutes for a practical use charge. Those that are familiar with the Makita brand will be aware of the enhanced battery protection system we have developed for our cordless systems, which is also applicable to the XGT platform.

This highly intelligent, unique system technology allows digital communication between the battery and the charger, as well as the battery and the tool, to optimise the charging process, reduce charge times and protect the battery from damage. This real-time digital communication actively monitors heat, overload, and over-discharge as well as delivering up to 2X longer sustained power during demanding applications.

“This year, we are celebrating 50 years of Makita’s presence in the UK and in that time, we have released hundreds of new products with a focus on developing battery and tool technology to achieve a truly cordless job site. Notably, Makita led the way with its adoption of lithium-ion as a battery system for power tools, which was an industry first when we introduced our LXT range in 2005, and today, this collection spans almost 300 products. More recently, we launched our 40VMax XGT collection which is our most powerful range of cordless tools to date and our new 8.0Ah XGT battery is a fantastic addition to this platform.

“We are incredibly proud of what have achieved since 1972, and we continue to invest in research and development so that we can offer a wide and useful range of cordless products and new technologies to aid productivity and efficiency on site.”

The HS004G 40VMax XGT Brushless 190mm Circular Saw is for cutting floors, trimming worktops and studwork sections to size. It has a no-load speed of 6,000 rpm and can produce bevel cuts of up 45, with a maximum cutting capacity of 60mm at 0 and 43mm when operated at 45.

The GA004G (1155mm) XGT Brushless Angle Grinder is an excellent addition to any tool kit. The tool-less guard is easy to adjust to any position without the need for a screwdriver and incorporates Makita’s Active Feedback Sensing Technology (AFT). If the rotation speed suddenly slows down e.g., kickbacks the tool shuts down, and features an anti-restart function, electric brake and soft start for operator safety.

The AS001G XGT 40VMax Brushless Dust Blower is an incredibly versatile machine and can be used across a range of tasks including tool maintenance and cleaning, blowing dust away from equipment and cleaning air conditioner filters thanks to its blower and vacuum modes.

Makita’s 40VMax and Twin 40VMax (80VMax) XGT product range currently offers a choice of over 70 products, which will continue to grow alongside our 18V LXT platform.

The DA001G 40VMax XGT Brushless Angle Drill is perfect for those awkward spaces, where a conventional in-line small drill would not be suitable. On account of the high torque output, the tool features a torque limiter to prevent injury and twin LED job lights for better visibility of the workpiece. It also benefits from our Automatic Torque Drive Technology (ADT), which automatically adjusts the output according to the load conditions.

Our XGT range isn’t limited to cordless power tools. We also offer a great selection of peripheral products and accessories including radios, fans, LED torches and lighting solutions, not forgetting the KT001G 40VMax XGT 800ml Kettle and CW001G 40VMax XGT Cooler and Warmer Box – perfect for when you need a cool drink, or to keep lunch warm (up to 60˚C) through the winter months.

Q How long does it take to charge the battery and are there any protections in place to prevent it from damage?

Q How wide is the XGT platform and which tools would you recommend plumbers and heating engineers look out for?

YOUR FIRST LINE OF defence

explains how socket testers can keep plumbing and heating installers safe when working with or around electricity.

As a heating and plumbing engineer, you may be installing bathrooms, showers or heating appliances, such as boilers and heat pumps, that require working with – or around –electricity. By taking basic steps, you can ensure yourself and your colleagues mitigate any risks posed by faulty electrical work and remain safe. Your basic, first line of defence, is a socket tester.

Socket testers can identify potentially unsafe conditions before any work is carried out on existing installations, or before connecting new appliances. They can be used to identify socket outlets which require a more detailed assessment as part of periodic inspection and testing.

All socket testers check the earth, live and neutral is the right way around. Some offer added features – they may include a buzzer in addition to LEDs to indicate a good socket or they may show a combination of indicators to identify which

particular fault type is present.

Earth loop impedance

There are three main categories of socket testers, simple, advanced and professional. The key differentiator with more advanced socket testers is in the ability to measure and display either ranges or numerical values for earth loop impedance.

A reliable earth loop impedance measurement is important to ensure that current protection devices achieve a fast enough disconnection time to avoid electrocution. In the case of an earth fault, loop impedance values must be less than those specified in the BS7671 Wiring Regulations. Advanced and professional socket testers will also indicate the quality of the earth connection. For detection of cross polarity at the incoming supply, specialist socket testers are required.

Fuse finder

Many heating and plumbing installers may only ever need a simple socket tester. With the added benefit of an audible sounder to confirm that the wiring is correct, the Martindale BZ101 can be used to check sockets that are not easily visibleor in

difficult to access locations. In addition, with the audible indication, the BZ101 can also be used as a basic fuse finder. When the correct fuse is pulled, the buzzer stops.

The CP501 classic check plug, meanwhile, is a quick and easy way to ensure that 13A sockets are correctly wired. Featuring three bright long life LEDs, wiring faults are indicated by one of the LEDs failing to illuminate, with the pattern of lit LEDs indicating the type of fault detected. This fail-safe system means that any LED not lit indicates a fault. The fault condition can be easily identified from the list front of the label.

an industrial version of plug, which meets BS 4343 / IEC309 standards, the CP201 (like many other Martindale socket testers) can identify 28 fault conditions. Wiring faults are instantly indicated by one or more of the LEDs failing to illuminate, with the pattern of lit LEDs indicating the type of fault detected.

For checking industrial sockets on 100V centre tapped circuits, the CP301, which is fitted with a distinctive yellow 110V 16A plug (also to BS 4343 / IEC309), uses three bright LEDs to provide fail-safe fault indication. Furthermore, fault indications include Line 1, Line 2 and centre tap faults, plus Line 1 or 2 centre tap reversal. The CP201 is also available as a 32A version.

Socket testers remain a must have for any tool kit and can act as the first indicator of a fault, but they are no alternative to full verification of wiring installations. For that, it is necessary to follow the inspection and testing procedures set out in Part 6 of BS 7671, and you need a full set of test instruments which comply with the relevant parts of BS EN 61557, typically with a multifunction electrical tester such as Martindale ET4000.

Socket testers can identify potentially unsafe conditions before any work is carried out on existing installations, or before connecting new appliances.

LOOKING AHEAD: INDUSTRY CHALLENGES AND OPPORTUNITIES

Consumer concerns

One of the key challenges right now is the cost-of-living. It is anticipated that people will take cost-cutting steps that could become dangerous; skipping boiler checks or turning down water temperature, thereby inadvertently letting Legionella bacteria thrive. Therefore, educating the public about these dangers is going to be very important in the coming months and into the new year. Similarly, fuel poverty is a serious concern, so plumbing and heating engineers can be a trusted advisor and provide consumers with guidance on the different product options available.

Once winter has drawn to a close, temperatures will rise and so will the likelihood of droughts and water shortages. We’ve seen unprecedented heat throughout the summer months in 2022, and it has highlighted the need for drought preparedness. This is where engineers can provide continued customer support by monitoring and assessing existing systems to maximise efficiency.

Wider industry issues

From a capacity perspective, the skills shortage prevails. As such, we will be continuing our concerted recruitment

efforts to bolster the next generation of plumbing and heating engineers. This will be done through college collaboration and signposting individuals to quality training in a bid to increase the number of qualified professional engineers and stamp out the threat of both rogue trainers and rogue traders.

accessible and careers more satisfying. In line with environmental concerns and net zero objectives, a focus on water and energy efficiency and low carbon technologies will continue in 2023. The goal of the CIPHE has always been to better the lives of our members and the public, and that encompasses sustainable practices. By continuing to promote quality at every opportunity, we can work together to raise the status of plumbing and heating to a higher standard.

Priorities

There is always training available, whether it is upskilling on an existing technology, or to become proficient in new technologies. Along with ongoing training and CPD, there will be greater focus on apprenticeships and career progression which will make our industry more

CISTERMISERLAUNCHES EASYFLUSH EVO TO TACKLELEAKYLOOS

Cistermiser has announced the launch of its EasyFlushEVO range, which the company says will revolutionise WC flushing by bringing together the benefits of non-touch and leak-free flushing. The patented siphon flush design means there is no flush seal below the waterline, and the company says that unlike traditional flush valves, it will not leak due to debris, scale or seal degradation.

Richard Braid, Cistermiser MD commented: “We all know as an industry how much water is wasted through leaking toilets. According to experts Waterwise, a leaking toilet wastes between 215 and 400 litres of clean drinking water on average every day. Between five and 8% of toilets are estimated to be leaking, adding up to around 400 million litres of water leaking from UK toilets every day. Against a backdrop of the climate crisis and the

Road to Net Zero, losses like these are clearly unsustainable.

“That’s why the launch of EasyFlushEVO, calculated to save up to 78,475 litres of water per unit per annum, is so significant. Although it may not single-handedly solve the water wastage problem, it goes a long way to raising standards and is just one of the many highly innovative approaches we’ve taken to help address this industry-wide problem.”

Richard continued: “Simple to install for both new build and retrofit/refurbishment, the EasyflushEVO is a sensor-activated siphon dual flush valve that improves hygiene by preventing the cross contamination of pathogens with non-touch controls. Manufactured to high standards, the stylish and rugged sensor plate is made from stainless steel and has the option for mains or battery power, out of the box as standard. The patented EasyflushEVO dual flush valve provides the optimum hygiene and intuitive sensor design and is available to order with a 1.5” or 2” outlet fitting.”

As part of its investment into the range, the company is also launching the EVO CISTERN Sensor WC flushing kit which offers a non-touch leak-free flushing solution, complete with a fill valve and concealed cistern with 1.5” flush pipe outlet and flush cone.

Richard concluded: “As we introduce EasyflushEVO to the market, sustainability remains a key consideration: the role that efficient water solutions can play in the fight against climate change has never been more important. Collectively we need to innovate and invest along the entire supply chain and that’s why we have developed the EasyflushEVO another industry first for Cistermiser, who continues to lead the way in water efficiency management solutions.”
