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.

Rise in renewables

Even though this summer was not quite as warm and sunny in the UK as many of us may have hoped, it has, seemingly, not impacted the appetite for ‘renewables’ installation in homes.

Figures recently published by the Microgeneration Certification Scheme (MCS) indicate that the UK is on track for nearly a quarter of a million homes installing certified renewables this year.

The data from the MCS shows a 62% jump from the previous year with more households installing heat pumps and solar panels. MCS data also shows that in the first six months of 2023, more than 120,000 certified solar panels, heat pumps and other renewable technologies were installed in UK homes, the highest number ever by this point in the year.

It says that 2023 is the first year to average more than 20,000 solar panel installations per month, and the first to see more than 3,000 heat pumps installed per month. The data shows that there were 17,920 heat pump installations in the first six months of 2023.

This growing trend is one heating engineers may want to keep a close eye on. While installing solar panels on a roof and/or shifting to a heat pump-led heating system may not be for everyone, it is apparent that a growing number of households are opting for these technologies.

Installers rightly worried about the levels of consumer interest in these low carbon technologies may now begin to reconsider their impact on the sector and more fully investigate the growing number of training courses on offer to help them gain the skills needed for competent installations.

Barely a week goes by – at least it seems that way – without another organisation unveiling its latest low carbon training offer – many of which now include the Heat Training Grant, which will allow many engineers to receive £500 towards the cost of heat pump training.

Of course, right now for most heating engineers the ‘day-job’ remains the more traditional heating requirements, largely focused around boilers – and this is likely to ramp-up in the coming months as the heating season kicks into full gear.

But with consumer interest for renewables and low carbon solutions on the rise, and training for these technologies increasingly available, (not forgetting the grants for heat pump courses) it might be worth considering a move towards these options.

IDEAL HEATING LAUNCHES UK HEAT PUMP PRODUCTION LINE

Ideal Heating has launched its first UK heat pump production line as part of an investment in low carbon technologies.

Lord Callanan, Minister for Energy Efficiency and Green Finance, visited the company’s Hull factory to mark the start of heat pump production by the company in the UK. The new heat pump production line forms part of a £60m investment at the Hull site which includes an expanded distribution hub, a research and development centre and a heat pump manufacturing facility.

Shaun Edwards, CEO of Groupe Atlantic UK, Republic of Ireland and North America, said: “The transition to low carbon heating solutions including heat pumps is the biggest transformation in the business since we moved from coal to gas-fired boilers in the 1930s. The major investments we’re making at our Hull site send out a very clear signal about our commitment to the net zero transition and to re-modelling our business to meet the needs of our customers today and into the future.”

DATA REVEALS GROWTHOFLOW-CARBON TECHNOLOGY IN HOMES

More households are installing heat pumps and solar panels in the UK than ever before, with a 62% jump compared to last year, new data from the official standards body for renewable technologies shows.

MCS data indicates that in the first six months of 2023, more than 120,000 certified solar panels, heat pumps and other renewable technologies were installed in UK homes, the highest number ever by this point in the year.

2023 is the first year to average more than 20,000 solar panel installations per month, and the first to see more than 3,000 heat pumps installed per month.

PRICEDRIVESSALESVALUESUPWARD

Figures released by the Builders Merchants Federation (BMF) in its latest Plumbing and Heating Merchants Index (PHMI) confirms that price growth remains a factor in driving the rise in annual sales value, as year-on-year volumes are down. There are, however, signs that price growth is slowing.

Overall Q2 2023 saw a +3.9% increase in sales values compared to the same period last year, with no difference in trading days. However, growth stemmed entirely from higher prices (+7.2%) as volume was -3.0% lower than Q2 2022. Total value sales in Q2 2023 were -12.0% lower than in the previous quarter. This was a combination in reduction in volume sales, down by -8.9%, and prices falling by -3.4%.

BEAMA ANNOUNCES CHANGE OF LEADERSHIP

BEAMA, the UK trade association for manufacturers and providers of energy infrastructure technologies and systems, has announced that Dr Howard Porter is stepping down from his role as BEAMA’s CEO after 25 years with the business.

With Dr Porter stepping down, BEAMA has announced that Yselkla Farmer, currently Director of Public Affairs, has been appointed to the CEO role.

Farmer commented: “It is a great privilege to be taking on the CEO role for BEAMA. Howard leaves behind a strong legacy, and I am looking forward to working with a brilliant team and clear work program.”

CONSUMERSSEEKBETTER UNDERSTANDINGOFRENEWABLES

Over a third (34%) of British adults still aren’t aware of the most environmentally friendly way to heat their homes, despite the government’s goal of reaching Net Zero carbon emissions by 2050 – according to new research from Mitsubishi Electric and Ipsos.

Only 13% of respondents are currently aware of the environmental benefits that heat pumps offer, and 71% know little to nothing about how heat pump technology works. More broadly, over a third (34%) don’t know the most environmentally friendly ways to improve the energy efficiency of their homes.

Russell Dean, Mitsubishi Electric’s Residential Products Group Director, said: “Heat pumps are a vital technology on the road to Net Zero, but their full potential is currently not being realised in the UK. To make Net Zero a reality, the government must do more to raise awareness among households on how they can lower their energy usage with heat pumps and dispel any fears around cost and performance of the technology.”

HAMWORTHY LAUNCHES HEAT PUMP CPD

Hamworthy Heating has created ‘An Introduction to Heat Pumps’ CIBSE Approved CPD.

Created for specifiers and installers wishing to understand more about heat pumps and the latest industry developments, ‘An Introduction to Heat Pumps’ is the latest CIBSE-accredited Continuous Professional Development (CPD) course from Hamworthy Heating. Covering the main heat pump operating principles such as energy, refrigeration, technology and efficiency, the latest CPD offering from highlights the different types of commercial heat pump equipment available and explores the influencing factors which need to be considered before heat pump selection.

Leak PROTECTION

Figures from the Association of British Insurers suggest that water-related claims, including leaks, result in around £650m being paid out annually. Besides the financial cost, leaks can cause broader damage to property and possessions, as well as inconvenience to residents. By utilising high-quality components and proactive measures such as smart leak detection systems when carrying out improvement and repair work,

installers can help to strengthen their customers’ water systems for long-term reliability, improved leak resistance and greater peace of mind – even when they’re away from home.

Respond quickly

Leaks are never a welcome presence for homeowners. Whether it’s a small leak that’s gone unnoticed for some time, or a burst pipe that showed no prior warning signs, leaks can result in extensive damage.

With a burst pipe continually discharging water until turned off at the mains, damage isn’t limited to the ceilings, walls and floors. Surrounding pipework could also be damaged, alongside environmental issues, with every leak contributing to the millions of litres lost to leaks every day across the UK’s water network.

While leaks are more likely to occur in older buildings where pipes have corroded over time, more recent installations could also be prone to leaks. So, whatever the age of systems being worked on by installers, the best advice is to take a proactive approach to leak prevention.

This starts with the selection of fittings, informing how connections are made and the overall quality, strength and longevity of the system.

Permanent connections

Push-fit fittings and valves have become commonplace in recent years, relied upon by professionals to deliver reliable, leak-proof connections – particularly in places where traditional soldered or compression alternatives are impractical to install.

Pioneered by JG Speedfit, plastic push-fit fittings are precision engineered to deliver a reliable, leak-proof and permanent connection, with push-fit and multi-seal features underpinning performance. In practice, connections can be made quickly and easily, saving installers valuable time while facilitating consistent performance on every job.

To equip installers with a full suite of solutions to deliver leak-proof systems, the JG Speedfit range brings together pipes, fittings and valves. Combining familiar push-fit technology with Twist & Lock technology, installers can maximise durability and performance without the need for special tools. To provide further support to connections, Superseal Pipe Inserts can be used to improve strength and rigidity. Furthermore, when used alongside JG Speedfit Twist & Lock Fittings, the dual O-rings of the pipe inserts combined with the fitting’s own O-ring form a multiseal, which is an

Richard Bateman, Product Marketing Manager at RWC, explains how installers can build leak protection into systems.

additional step towards preventing leaks and offering greater protection.

With most leaks stemming from connection points, using solutions that strengthen these points is a reliable way to create a leak-proof system. Going further still, reducing the volume of connections overall will further reduce the potential for leaks to occur.

This can be achieved by installing longer pipe runs – with solutions like JG Layflat Pipe from JG Speedfit – contributing towards leak-proof systems for customers, but also reducing installation time for professionals. With the ability to bend around corners as well as lying flat for straight runs, the pipe coil can strengthen installations and reduce fitting time.

Detect leaks

For added security and peace of mind, installers should also look to methods of leak detection to quickly identify leaks should they occur on a system in the future. Here, technology can play a vital

role – not just in identifying the presence of leaks, but also in notifying occupants to enable a prompt resolution.

While big leaks can typically be spotted quickly without the need for equipment, low-flow leaks can be much harder to spot, with signs such as small increases in water consumption being easy to overlook. By

incorporating smart technology into systems leaks can be identified quickly and properties protected from further damage.

Solutions like the Reliance Valves MultiSafe Leak Detector can detect unusually high water usage in real-time and take preventative action by shutting off the supply and alerting the homeowner via text or email. Through constant monitoring of water usage and regular micro-leakage monitoring functions, the system can detect leaks before more water is lost and greater damage caused.

By taking a proactive approach to leak prevention, installers can strengthen their customers’ plumbing systems to improve efficient performance and protect against leaks. With the addition of detection systems, customers can benefit from greater peace of mind and security, even when they’re away from home or leaks are hard to spot.

DRIVES HEATING EFFICIENCY AI

Anew technology has been launched by Navien UK which uses artificial intelligence to help homeowners utilise their heating system more efficiently. Navien’s ON AI is designed to work with the company’s ON technology, which features in its NCB ON range of Combi Crossover boilers, as well as the company’s Smart Plus and Smart Plus ON AI controllers to create a network of integrated heating controls throughout the home.

Featuring firmware-over-the-air (FOTA) capability, which allows the updating of the boiler’s built-in AI technology wirelessly, ON AI can provide homeowners with a Home Energy Management System (HEMS) report, to give them an in-depth analysis of their heating and hot water usage.

Mobile app

Through a mobile app, a number of technologies can be accessed designed to help make heating homes simpler, including Smart Diagnostics which allows homeowners to diagnose potential issues that may occur, quickly and accurately. Another tool is Smart Forecast which harnesses data from OpenWeather to respond intuitively to the current weather conditions to ensure the home remains at a comfortable temperature.

“We’ve been developing an industry-first technology that will help make users’ lives that little bit easier,” said Sean Keleher, Technical Director at Navien UK. “Technology is at the forefront of our daily lives and this revolutionary AI is the next step in helping homeowners utilise their heating system more efficiently while using less energy and ultimately cutting down energy bills.

With artificial intelligence (AI) being increasingly used in many areas of society, PHPI discovers how one boiler manufacturer is incorporating it to help boost the efficiency of heating systems.

“With diagnostics at your fingertips, boiler faults are flagged within the app and an engineer is notified immediately to identify any problems before they become more serious, which in turn will help minimise boiler downtime –a particularly important tool in winter, where maintaining and restoring heat within the home is a priority. The technology is also useful for residents of rental properties, as they’ll be able to flag issues to their landlord before they develop, speeding up the maintenance process and again, reducing downtime.”

Away from home

ON AI also includes Geofencing which allows users to switch the boiler on or off, based on their proximity to the premises up to a radius of 5km, helping reduce hot

water waiting times and preserving energy when occupants are away from home throughout the day.

Sean added: “Geofencing is a game-changer for adding even more convenience to users’ lives by providing passive heating controls based on their location. When leaving the home, the boiler will switch off once the user, and their mobile phone, is out of the designated boundary. The boiler will then switch back on when the user re-enters the radius, saving both time and energy in the process. And the app can be accessed on multiple devices, meaning each member of the household can utilise these tools to suit everyone’s day-to-day lives.”

Navien has designed the new technology to work in conjunction with its ON range of Combi Crossover boilers, including the NCB500 ON and NCB700 ON.

With the number of heat pumps being installed on the rise, Chris Harvey, Head of Marketing, Stelrad Radiators Limited, looks at how radiators can work with low temperature heating systems.

THE LOW -DOWN

Radiators have been around for well over a century in some forms, but the radiators of today are a very different beast to their predecessors and offer an efficient, straightforward and proven way of sharing heat effectively around homes up and down the UK and Ireland.

Radiators still provide the heat sharing skills in around 90% of all homes in the country and need to be sized properly to provide comfort heating. Appropriately sized radiators will work well with heat pumps if insulation levels are appropriate and, depending on the home, larger radiators are installed or K3 design radiators are specified to provide the additional metal surface areas required to provide the levels of heat needed to keep homes cosy.

Genuine rethink

The advent of low temperature heating systems in response to the need to decarbonise domestic heating systems across the UK is seeing the first genuine rethink in heating for many decades. Despite the desire of many in the sector to fight against the loss of the traditional fossil fuelled boilers that have been the mainstay of the heating industry for years and years, heat pumps are making significant headway.

The change is coming, and the farewell wave to boilers in new build properties from 2025 will inevitably be followed by a drive – driven probably by legislation of some sort – to switch to renewable heating in existing properties within a few years and almost certainly by 2035.

Gaining ground

The UK heating industry – in the form of its installers at any rate – is making the decision to welcome heat pump technology with open arms with recent independent

research highlighting that as many as 70% of all installers in the UK are looking to be trained to install heat pumps in 2023 – up from just 19% this time last year.

Installers operating at the sharp end of the industry are adopting the sensible approach that with heat pumps clearly being encouraged by the Government, increasingly being accepted by the new homes sector and offering a very clear option for replacement heating systems, it’s clear that heat pumps – in particular air to water heat pumps – are gaining significant ground when it comes to acceptance as the key technology for renewable heating and hot water in the UK.

More sizes

The rise of the heat pump is seeing the need for larger and higher capacity radiators. Stelrad has responded to these needs by broadening its already massive range of sizes and shapes for its most popular radiators and the introduction of a wider range of vertical radiators. It is also meeting the enhanced need for its K3 radiators – with three panels and three fins offering 50% more heating capacity from a radiator with the same footprint as a K2 format radiator for example.

Stelrad continues to mount its ‘Fit for the Future’ campaign, highlighting that radiators are very much able to provide the levels of comfort heating and hot water required in UK homes, when paired with heat pumps. The arrival of the new upgrade to Building Regulations brings with it a realisation that the key figure to bear in mind is 55°C – the maximum flow temperature for all new wet heating systems from this date.

Understandable questions

The arrival of the low temperature heating system has brought with it perhaps understandable questions that installers and specifiers want answers to. Can we still use products we use now with traditional boiler driven heating systems if the heat source is a heat pump? Is there anything we need to consider that we take for granted nowadays?

The answer is of course yes – we need to look closely at how to ensure that the heat generated is shared effectively in the new home or the existing home that is having its heating system upgraded.

Sizing calculator

In new build housing, using a heat pump-based solution is a relatively simple solution. The heating system can be designed into the home at the outset so you know the parameters in which the heating system has to operate – the

The key to radiators operating well in any situation is to size them properly at the outset.

method of construction, the size of the rooms, the number, type and size of doors and windows – so the heat loss calculations can be done up front and radiators sized accordingly. The levels of insulation can be agreed at the outset that will provide the best support for any heating system chosen, whether radiators or underfloor heating.

The key to radiators operating well in any situation is to size them properly at the outset, which involves accurately working out heat loss calculations to achieve the necessary number of BTUs required to provide comfort heating in each room and to select a radiator that can provide that level of heating.

Stelrad offers a simple to use and free radiator sizing and heat loss calculator along with a Renewables Advice page on its website. Facts and helpful information are also shared through a free to take CPD also available on its website.

Radiators are very much ‘fit for the future’ but as always, correct sizing will need to be undertaken to ensure that they keep the home warm and cosy. But can radiators work well with air source heat pumps? Very definitely yes, they can – and they already are in a host of installations across the UK.

AIR REMOVAL

Air and dirt in hydronic systems cause operational problems and their removal is a key factor in achieving maximum efficiency. Steve Elsmore, Senior Technical Support at Altecnic, breaks down why the removal of air from systems is important and describes the components that can be installed to remove air from systems.

QWhat is deaeration?

Deaeration is the process of separating air from water and then eliminating the air from a water distribution system.

QWhy is air present in the water?

Cold mains water used to fill systems is often more than 95% saturated with dissolved air consisting of a mixture of Oxygen-O2 (21%) and Nitrogen – N2 (78%) and other trace gases which can exist in a dissolved state integral with the water molecules. With non-dissolved air, the gases are separate from the water molecules and are entrained in the form of bubbles of various sizes down to the microscopic level.The ability of water to retain air is proportional to pressure (according to Henry’s Law) and inversely proportional to temperature. When the temperature or pressure of water is changed such that the solubility is reduced, dissolved air will be released from the water in the form of bubbles.

There are three forms of entrapped air:

● Stationary air pockets at high points

● Entrained micro-bubbles

● Dissolved within water

QWhat problems arise from air in water?

Nitrogen is the main cause of classic air problems whereas oxygen is the main cause of corrosion. Air management is an important factor in any closed loop hydronic system. If neglected, the

presence of air can lead to many unexpected consequences; premature deterioration of equipment and decrease in overall system efficiency. Free gas bubbles may significantly affect the circulation. As bubbles pass along a water distribution system, they can coalesce (bind together) in areas of low velocity to create localised air pockets which remain in place and reduce flow rate.

Control of dissolved oxygen is a key aspect of controlling corrosion and to manage the corrosion risk, the oxygen concentration should ideally be reduced as quickly as possible after commissioning. Oxygen is a highly reactive gas and if air is constantly present in a system because of inadequate deaeration, continuous exposure would accelerate corrosion of ferrous materials, affecting steel piping, cast iron boilers, expansion tanks, eventually leading to reduced performance and leaks.

The mixture of air in water is acoustically active. Flow noise in pipes, fittings and radiators is quite irritating for building occupants and is a sign of the presence of air in the system.

QWhy is deaeration important?

A new hydronic system begins life completely filled with air and the main objective is minimising the amount of air present during filling and then eliminating the remainder. Traditionally, systems are filled from the bottom up to allow air to be expelled by air vents. Hydronic balancing and control valves require deaerated water to achieve designed flow characteristics. Presence of air in the system could change the Kv of balancing valves and their water

flow characteristics. Air would also cause excess turbulence and unstable pressure signals downstream of a valve.

Commissioning should not be attempted without prior elimination of air from a system. Unlike water, air is a good insulator. If air is present in heat transfer devices such as coils, radiators and heat exchangers for example, it significantly reduces the rate of heat transfer and overall efficiency. Air trapped in a hydronic heating system can reduce energy efficiency by up to 10% and contribute to corrosion which in turn can result in blockages in pipes and equipment.

Maintenance work on systems, fresh makeup water and porous joints and non-metallic tube are examples of how air can be repeatedly introduced into a system after it is put into service.

QHow does deaeration work?

Automatic Air Vents are designed to continuously remove air without manual intervention which accumulates in hot and cold-water distribution systems. Placed at high points in a water distribution system Automatic Air Vents will ensure efficient

Automatic Air Vents are designed to continuously remove air without manual intervention which accumulates in hot and cold-water distribution systems.

initial venting of accumulated air to atmosphere during filling because the water is not flowing. Air vents will not capture bubbles from flowing water.

After initial venting, the system water will still contain micro-bubbles and dissolved gases. Gas bubbles and micro bubbles are carried along with the flow therefore separation is only possible with specific devices. Micro bubbles are extremely small and occur in large numbers and have a tendency to stick to surfaces making the separation process more difficult. With dissolved gases, the gas molecules are bonded between the water molecules in such a manner that they can only be removed by means of pressure reduction or temperature increase. Due to the pressure and temperature differences in a system, dissolved gases can desorb into bubbles.

QWhich products are used for deaeration?

Air separation is achieved using specific products at various locations. As described above, Automatic Air Vents will provide system venting during initial filling of the system (and draining where necessary).

Air vents are not intended for operational venting when directly installed on flowing pipes. They are designed such that accumulated gases are vented off but they are not able to separate bubbles from flowing water.

The design of separators causes the flow velocity to be locally reduced within the main body allowing existing bubbles in

the less turbulent water to rise to the top and the gases are expelled through an integral, top mounted Automatic Air Vent. Separators for micro-bubbles are compact units and are suitable for operational de-gassing and continuous venting. An internal mesh type of baffle with sharp edges induces the micro-bubbles to cling to the surface which then coalesce into larger bubbles which rise and are expelled to atmosphere. Manual Air Vents are often sufficient to eliminate air pockets in heat emitters such as radiators.

INTERGASLAUNCHES XTEND HYBRID SYSTEM

Xtend is the new hybrid heating system from Intergas, which the company says will cut gas consumption by up to 82.5% when paired with any Intergas (ErP) combi boiler.

Developed by the Intergas R&D team in the Netherlands and manufactured at the company’s factory in Coevorden, the Xtend Hybrid has been designed to provide the comfort of a traditional heating system, so homeowners will always have heat and hot water where and when they want it. The Hybrid heat pump is quiet, with a decibel level of 36 dB(A) at five metres.

The Xtend Hybrid system comprises an Intergas combi boiler (any Intergas combi), an indoor control unit and an outdoor 5kW split Air Source Heat Pump. The small indoor control unit provides a range of siting options within the household and the low loss header enables the indoor unit to be fitted anywhere within 15m of the boiler. The lightweight Air Source Heat Pump can be sited anywhere outside the property, within 25 metres of the indoor control unit, and measures 68.9cm x 96.8cm x 36.2cm.

The Xtend Hybrid unit comes with a 7-year warranty when installed as part of the full Intergas solution and, if an Intergas

(ErP) combi boiler is already installed, then Xtend can be retrofitted to that combi and the warranty increased by two years as part of the full Installation and Service option (T&Cs apply).

Remote control

Installers can also pair the Intergas ComfortTouch control with the system for more efficiencies as ComfortTouch recognises the appliances and automatically optimises their settings. Installers can continue to use the Service Dashboard for remote control, monitoring and adjustments, and homeowners can use the ComfortTouch app to turn their

smartphone into a smart thermostat to control their central heating remotely.

Speaking about Xtend, Gary Rudd, Managing Director, Intergas Heating Solutions, said: “We are committed to reducing our reliance on fossil fuels and pushing high efficiency products that deliver large CO2 reductions across the broadest possible range of UK houses, which reduce the real-world energy costs of the home heating system. With our Xtend Hybrid we have a practical solution to decarbonising home heating and hot water production and, when the hydrogen infrastructure is in place, our natural gas boiler can either be upgraded to or be replaced by our Xplore hydrogen boiler for a 100% sustainable heating system. Right now, the Xtend Hybrid offers everyone a practical and economical route to greener heating.”

A ‘lifetimeof training’ BEGINS...

Back in May, PHPI met Josh Scott, winner of Logic4training’s ‘Lifetime of Training’ prize –everything he needs to become a successful building services installer; from practical training to a new website, Checkatrade membership and even marketing support. Josh completed the first step, a Plumbing Diploma, in August and has now moved onto a Gas Managed Learning Programme (MLP). Once a fully qualified gas engineer, Josh will benefit from £1,000 worth of training every year for a decade! We recently caught up with Josh to see how he has been getting on.

QHow are you feeling about the first part of your training?

“I’m thrilled with how everything’s going. I now have a Plumbing Diploma. The first part of my training went very quickly. I enjoyed it so much; I didn’t want it to end. “Now I’m taking a bit of a breather from learning before I start my gas training in a few weeks’ time.”

QHave you been working while you’ve been training?

“I’ve been working with my Dad and brother at Belfor, a fire and flood restoration company. My new skills are proving useful! I’ve also launched my own company, ‘Accolade Property Services.’ I’ve been a tiler for a while now, but this prize has really opened things up for me. Tiling’s fine, but it’s a messy trade and it’s great that I can now spend more time plumbing, which requires more skill - I love the problem-solving aspects.”

QThe prize was about more than building services training, what else have you been learning?

“I’ve been working on developing my social media presence - that was another part of the prize. Harry Budd, Logic4training’s Content Creator, has been helping me make some short videos that I then post on my new Instagram, TikTok and You Tube accounts.

“It’s fun choosing what to put up and learning how to edit and stuff. I can see that the three channels are aimed at different audiences and at the moment, think Instagram is the most professional –the most likely to lead to jobs. I’ll also have

a think about Facebook. That could be another useful way to market myself.

“When I’ve got my ACS and registered with Gas Safe, I’ll take up my year’s free membership with Checkatrade. I feel so fortunate to have won Logic4training’s competition. The skills I’ve learnt this summer provide me with loads more options and opportunities – I can’t wait to get back to learning!”

GETYOUR FINANCESIN SHAPEFOR

2024

business challenges 2024 will bring. James Chillman, UK Country Manager for Fergus explains how.

businesses. It is not easy – whether you are a start-up, sole trader, or even a more established, larger contractor with multiple vans on the road. However, there are some tasks you can start on right now, giving you more of a chance to relax and feel like 2024 will be a great year for your business. Here are five hints and tips to help plumbing and heating installers prepare for Christmas and the New Year as small businesses.

Mark key Tax Dates on your calendar

One of the first steps to financial preparedness is marking important tax dates on your calendar. For small business owners, it's essential to be aware of deadlines for filing taxes, VAT returns, and other financial obligations.

HMRC often has specific deadlines, so staying organized and meeting these dates will prevent last-minute panic and potential penalties. Utilise online tools or accounting software to set reminders for upcoming tax deadlines, ensuring you don't miss any critical dates.

Notify clients of closing times

Christmas and the New Year are times for everyone to take a break and spend quality time with loved ones. As a small business, it's crucial to communicate your closing times to clients well in advance.

Send out personalised emails or make phone calls to inform them of your holiday schedule. This will help manage their expectations and reduce any last-minute demands. Transparent communication fosters good client relationships and ensures they are aware of when they can expect your services to resume in the New Year.

Invoice on time

Late payments can significantly impact a small business's cash flow, especially during the holiday season when expenses might be higher. Ensure you send out invoices promptly and accurately. Don't delay in following up on any overdue payments to maintain a healthy financial position for your business. Additionally, offer flexible payment options to make it easier for clients to settle their bills during this busy period.

Address the admin struggle

As a small business owner, managing administrative tasks alongside your day-to-day work can be challenging. It's crucial to find efficient solutions to handle paperwork and invoicing. This is where Fergus Essentials comes in.

Tool storage FOR ELECTRIC VANS

bott Smartvan discusses how to get the most from van storage –focusing on van racking for electric vehicles.

In recent years we’ve witnessed the launch of a growing number of electric van models. From small EVs designed to neatly swerve through city traffic to larger vehicles primed for big on-site jobs, tradespeople and fleet managers have a suite of vans to choose from.

The interior of these vans requires the same level of organisation and inventory management as any other vehicular workspace. As such, many drivers opt for a van racking system. There are plenty of different van racking solutions available, from simple DIY options to professionally installed kits. But what should you be looking for? And how do you make sure it fits your requirements?

In this article we’ll discuss how to rack out electric vehicles, whilst continuing to make the most sustainable decisions possible.

Choosing van racking for an EV

From inexpensive ply solutions to lightweight metal systems, it’s important to choose the right van racking kit for your vehicle. The wrong one will cause plenty of frustration for you day-to-day, and even cause damage to your van’s interior, tools and equipment. When it’s time to level up the interior of your van, or upgrade your entire fleet, getting it right the first time will save you a lot of money in the long run. Firstly, you need to pick a van racking kit made from robust, durable materials. Picking a more financially modest setup is tempting. After all, your business’s bottom line is the difference between struggling and thriving. Ply options are popular because of their smaller price tag. However, these systems can be prone to damage. And when your van racking gets damaged, everything onboard is in danger.

Future proof

It’s natural for your requirements to change over time, and your van racking should mirror that. Whether you need different tools, or simply want to change up your layout for more efficient ways of working, wooden and other drill-in options make life harder. Not only are these options heavy to move around, but when they’re physically fixed in place making alterations is a big undertaking. Look for no-drill, lightweight options to help you prep for whatever comes your way over the next few years in your chosen field.

A sustainable option

Once you’ve invested in an electric vehicle, why undermine it with bulky van racking?

When you’re driving to site, or to multiple locations, every day, heavy racking kits will impact your fuel consumption in a big way. A lightweight metal option will lessen your vehicle’s burden on the environment with fewer fuel top ups needed.

Space saving

No matter your trade, you will need space to move in the back of your van. Whether you need to work in the vehicle or need extra space in between the racks to secure large items. Solutions such as bott Smartvan’s steel racking systems are designed to follow the side profiles of your specific van, giving you extra load space without compromising storage capacity.

The latest iteration of bott Smartvan’s offering, bott modulo3, is well suited to EVs due to its easy-to-fit, no-drill nature. The racking and mounting brackets fix to existing points in the van, meaning that no drilling into the vehicle body is required. This is especially important for electric vehicles, eliminating the risk of drilling through electrical lines.

Van racking for plumbers

The bott Smartvan team recently completed a full van racking setup for a VW ID Buzz Cargo Commerce Plus for tradesman, Dave. Just like with other makes and models, the racking lent itself perfectly to the specific shape of the ID Buzz, maximising storage capacity at every opportunity. The vehicle's interior is pretty compact, and so this was particularly important.

Previously, Dave had built his van racking from ply himself. Although this got the job done, the actual racking was heavy and hard to adapt. It also took a long time to get right. He picked bott Smartvan for his upgrade due to its reputation for great design and quality.

When thinking about the changes to his day-to-day, Dave said that everything is now much easier to find in the vehicle, it’s also much quieter which is often a plus point if you’re on a quieter site or at-home job rather than on a busy site. He was also grateful for the no-drill system as there was no threat to the battery or any electrical wiring.

“Literally the best racking and storage I’ve ever had in a van and that’s over 40 year’s old. bott is a joy to deal with. They are super professional and friendly. My van is a joy to work out of now, with everything neatly stowed away and easy to find.”

The team at bott Smartvan are available to chat through your EV setup and can guide you through the entire van racking process.

Please www.rdr.link/pax013

The team at bott Smartvan worked with Plumber and Heating Engineer, Glenn Wakeling, to optimise his van interior with bott modulo3. In transitioning from bott modulo2 to the latest edition Glenn has benefited from the increased organisation provided by the setup.

Glenn said: “The racking has changed the way I store items in my van in a massive way. I am generally more organised and work tidier. I know where every nut, bolt and washer is and can get to items a lot quicker.”

He is able to store all the tools he uses in the side walls and under the half deck, leaving plenty of floor space to manoeuvre and store work materials, such as boilers, flues and pumps.

One of the standout factors has been how many customers have commented on how professional his van now looks. Some have even asked for tours of the van to see how it all works! Other tradespeople have also requested a sneak peek.

Accessories are a big part of the customisation process. Glenn had struggled to find a solution for storing different sized cases safely, without them rattling or sliding around the vehicle. The new cases stay put on the racks during transit, without needing drills to secure them, which means they keep everything safe while being flexible – he can move them around his van based on changing requirements.

PRACTICE

Socket testers are a first line of defence for plumbers when it comes to electrical safety. Steve Dunning, Managing Director of Martindale Electric, explains why a socket tester should be in every plumber’s toolbox.

Plumbing and heating installers often work in environments where electrical systems and appliances are a significant part of their daily tasks. Boilers, underfloor heating, kitchen fixtures, hot water systems: plumbers frequently encounter electrical systems and sockets, and the safety and proper functioning of these electrical components are paramount to protect both the plumber and the end-users. One essential tool that every plumber should have in their toolbox is a socket tester.

A fundamental step in ensuring the safe operation of electrical outlets is the verification of correct wiring. From simple 13 Amp outlets to industrial 3-phase sockets, proper wiring is crucial to prevent potential hazards.

Electrical hazards

Socket testers are convenient and easy-to-use devices that can quickly identify potentially unsafe conditions in sockets, acting as an initial indicator of potential electrical hazards and allowing plumbers and electricians to identify and rectify faults before they cause electrical shocks, fires, or damage to appliances or equipment. Although never a replacement for a wider inspection and testing process, socket testers provide a rapid and straightforward method to assess the condition of electrical outlets without the need for complex equipment or extensive technical knowledge. Socket testers perform polarity testing by checking if the earth, live and neutral wires are correctly connected. This basic function is present in all socket testers. However, some models offer additional features to enhance functionality. These features may include a buzzer in addition to LED indicators, providing both visual and audible confirmation of a properly wired socket. Some advanced socket testers can even indicate specific fault types through a combination of LED patterns, allowing for quick identification of issues.

Types of Socket Testers

There are two main categories of socket testers: simple and advanced. Simple socket testers, like the Martindale CP501, are ideal for electricians and plumbers alike. The Martindale CP501 classic check plug is the simplest option, specifically designed to ensure the correct wiring of 13A sockets. Featuring three bright long-life LEDs, it indicates wiring faults by the failure of one or more LEDs to illuminate, with the lit LED pattern indicating the type of detected fault. Its fail-safe system ensures that any unlit LED indicates a fault, with a clear display of the most common fault types on the front label.

The BZ101 includes a buzzer and is particularly useful for checking sockets that are not easily visible or located in hard-to-reach areas. It can also double as a basic fuse finder, ceasing its buzzer when the correct fuse is pulled. The new BZ701 is a development of the standard and bestselling BZ101. It adds a supply polarity test to ensure the incoming supply is correctly wired and Live + Neutral have not been swapped.

For more advanced options, two recently launched socket and non-trip earth loop testers, the EZ165 and EZ365 are compact but powerful testers which detect 28 fault conditions, check the mains voltage level and show how safe the earth wiring is by carrying out a non-trip earth loop test and indicating its value in six discrete ranges. This test is critical for ensuring the safety of a electrical system, as a low earth resistance is essential for safety disconnection devices to work properly and prevent electrocution when faults occur.

The EZ365 model also includes additional features, such as an incoming supply polarity swap test and the ability to trip test 30mA RCDs. The L-NE cross polarity test detects a serious fault condition that cannot be identified by many normal socket testers and is easily activated by using the touchpad on the EZ365. Faults are also indicated audibly on this model.

For commercial and industrial environments, socket testers like the Martindale CP201 can identify up to 28

fault conditions. These testers employ LED indicators to instantly signal wiring faults, with the specific pattern indicating the type of fault detected. The CP301 is designed for checking industrial sockets on 100V centre-tapped circuits, providing fail-safe fault indication through three bright LEDs. This model is also available as a 32A version to suit different applications.

While socket testers can be lifesavers by acting as initial fault indicators, they are not substitutes for full verification of wiring installations. Plumbers should follow the inspection and testing procedures outlined

in Part 6 of BS 7671. This entails using a comprehensive set of test instruments that comply with the relevant parts of BS EN 61557, such as a multifunction electrical tester like the Martindale ET4000.

Plumbers dealing with electrical systems must prioritise safety to protect themselves and end-users. Socket testers play a crucial role in ensuring correct wiring, identifying potential faults, and preventing hazards. From simple models with audible indicators to advanced testers capable of detecting numerous fault conditions, socket testers provide an indispensable tool for plumbers.

However, it is important to remember that socket testers are part of a broader inspection and testing process outlined in industry standards. By incorporating socket testers into their toolkit and following the appropriate procedures, plumbers can contribute to a safer electrical environment for themselves and their customers.

ROOMFOR M anoeuvre

PHPI tries out some of Carhartt’s rugged workwear, designed to deliver both comfort and flexibility.

What you wear whilst at work is not always the first consideration for some tradespeople. But if you are fitting high-quality products and using reliable professional tools and equipment every day, why wouldn’t you want to be wearing rugged, professional clothing which can help to make a working day more productive and comfortable?

Carhartt is an American brand with a long history of producing workwear – the company has been in business since 1889 when it was founded in Detroit. Its workwear has recently crossed the Atlantic with many UK tradespeople checking out the company’s clothing, and we recently got hold of some of its workshorts, tops and caps.

Cap

Whether it’s to keep the sun out of your eyes, to protect your face from rain or just to keep messy hair hidden away, caps are extremely versatile. Carhartt has a broad range of caps, including mesh backed options, but we got hold of a canvas cap in Jade –although a variety of colours are available in both neutral tones and eye-catching colours to help wearers be easily visible on the job site.

The caps come with a sweatband lining that has been designed to wick away sweat and keep you feeling fresh and they also incorporate a technology to help prevent the build up any unpleasant odours. There is a pre-curved visor, to help protect the face and eyes from the sun's harsh glare or from the rain, plus a neat Carhartt logo on the front, and back, where hook and loop provides a simple way to adjust the size to ensure a snug fit.

Bodywarmer/Vest

Today many people call these tops Gilets – although we grew up calling these bodywarmers – but whatever term you use this is a really handy garment for keeping your core warm on a cool day but when a full jacket might be too much. Plus, the lack of sleeves allows plenty of room for movement.

Carhartt’s jacket is insulated, providing that extra warmth that is handy on a chilly day. It features Rain Defender technology which is designed to make water bead-up and roll off –helping keep the wearer dry in showers, while the Wind Fighter technology helps to keep the breeze off the body – helping you stay warm. Perhaps most noticeable are the levels of storage in the garment, with the bodywarmer including a large number of pockets. The left chest pocket has a zip,

handy for keeping valuables safe, while two lower front pockets feature a hidden snap closure. Inside the vest, there are two further pockets, one with a zip, and the other with a hook and loop closure. At the bottom of the garment there is a handy drawstring – allowing the user to adjust the vest to fit, keeping it tight to the body on cooler days.

a variety of colours are available in both neutral tones and eye-catching colours

T-Shirt

It’s been more than 30 years since Carhartt’s K87 pocket T-Shirt first made its debut, and we took delivery of one in Jade-Heather, a new colour released by the company in Spring this year. A number of other colours including Black, Navy, Port, and White are also available. The T-Shirt is made with heavyweight cotton and features a rib knit crew neck. The K87 is cut for a relaxed fit with and has a chest pocket, in case you need to keep essentials close at hand. The slightly loose style makes for a comfortable fit.

Work Shorts

Great for the summer, although preferred by some throughout the year, work shorts need to be rugged, practical and hard wearing.

We got hold off a pair of the company’s Rugged Flex Relaxed Fit Canvas Cargo Work Shorts, and fabric used in them feels tough and flexible. But what really catches the eye is their pockets. There are two large pockets at the back, fastened with tough hook-and-loop, and two at the front – deep enough to hold tools, phones, coins etc... Plus, on the legs, there are two Cargo style pockets, also secured with hook-and-loop. These also have

additional storage points on the outside, for further tools or equipment – handy for some pliers or snips. There is also a small logo detail on the rear pocket which provides a nice contrast against the grey shorts.

TEST FOOT FORWARD

No two days are the same for a heating engineer. There are any number of different tasks ranging from a low to high difficulty and it is essential to make sure you are prepared for anything the day could throw at you.

We know how important it is to have the right tools for the job. Not only are wait times reduced, resulting in happier customers, but you are also able to measure the correct parameters efficiently.

We also understand that plumbers and heating engineers need to be able to confidently rely on their tools. As a worldwide manufacturer of measurement instruments for heating engineers for a variety of HVAC applications, this is our expert opinion on the top five measuring instruments heating engineers might need.

Flue Gas Analyser

An electronic flue gas analyser is a common tool relied on by heating engineers all around the world, especially if you’re performing tests on small combustion plants or heating systems. Flue gas and emission tests are ideal for

determining the levels of heating energy that is lost as well as the pollutants that are emitted. The analyser measures the key gas components within the process of combustion and aids you in ensuring the boiler is performing optimally and safely.

Thermal Imaging Camera

When you’re working in the world of HVACR, a thermal imaging camera really is the perfect addition to a tool box. They are able to help in the detection of a range of issues from radiator blockages to damaged pipework without causing any unnecessary damage to a customer’s property. This means you can carry out regular high level of work without causing extra cost and wait times.

However, heating systems aren’t all a thermal camera can assist with. They are perfect to check that ventilation and air conditioning units are working correctly, ensuring a good level of comfort indoors. They are also ideal for locating areas with water damage and dampness, enabling you to spot potential areas where mould could grow, so you can take preventative action.

Testo explores some of the key test and measurement tools heating engineers should consider.

Digital Manifold

You might see a digital manifold and think of a refrigeration engineer. However, as heating systems are replaced, in order to take a step closer towards the green heating technology and Net Zero goals, the tools you use as a heating engineer must adapt. Digital manifolds have already been proven as an effective tool for installation and servicing of air conditioning and refrigeration systems. To stay up-to-date consider looking into heat pumps and digital manifolds.

Smart Probes

Smart probes are the perfect tools for smart measurement. There are a variety of smart probes for all HVAC applications that connect to your measurement instruments or a smart phone or tablet. Not only are smart probes available to purchase individually, but they are also in kits tailored to different needs. For example, the testo Smart Probes Differential Temperature/Pressure

kit is perfect for heating engineers as it allows the measurement of flow and return temperature on underfloor heating and radiators, gas flow, static pressure and can perform a drop test.

Voltage Tester

A voltage tester allows installers to test electrical systems and equipment easily and precisely. Some voltage testers have

LED displays, which shows the voltage indication clearly and distinctly from every possible position. These can also be sold in useful kits, like the new electrical kits from Testo including a non-contact voltage tester for precise and professional measurement of electrical parameters.

EXPANSION VESSELS AND LEGIONELLA RISK

Expansion vessels are an important integral part of pressurised hot and cold-water systems, particularly in larger systems such as hospitals – as Roy Sullivan, Senior Consultant,

Expansion Vessels are designed to protect the water systems infrastructure from damage caused by pressure build-up and pressure fluctuations. When installed correctly and operating as designed, the volume of water within the vessel will fluctuate according to demand on the system, be it a hot or cold system, to negate the pressure issues associated with a boosted or mains supply feed to the system.

Main types

The three main types of expansion vessels that are found in most, if not all installations are; Diaphragm, Bladder, and Flow through. Your Legionella risk assessment should identify the location and type of vessel(s) you have and make recommendations concerning Legionella proliferation mitigating measures.

The Water regulations guide R17.3 states that;

“Some doubts have been expressed about the desirability of using single-entry expansion vessels. The use of single-entry expansion vessels effectively forms a vertical dead leg through which there is no flow of water and concern has been expressed about the possibility of bacterial growth within the vessel. It is considered preferable, therefore, that an expansion vessel with both inlet and outlet connections should be installed, wherever practicable so that the water content of the vessel is constantly changed. Where expansion water is accommodated separately the expansion vessel should be of an approved flow-through type and should comply with the requirements of BS 6144 and BS 6920”

Flushing

Some expansion vessels may have a rubber diaphragm that may be a source of nutrients for Legionella. Diaphragm or Bladder vessels (Diaphragm or bladder vessels should meet BS 6920) that don’t have regular flow through are often seen installed on lengths of pipe that do not allow water to move and the expansion vessel itself creates a dead end or dead leg.

With the combination of organic material and the potential for low-flow areas, Legionella has the ideal conditions to grow and multiply. To manage these types of vessels and the adjoining pipework, they must be flushed regularly in line with current guidance and your Legionella Risk Assessment.

Minimise the risk

So how can we minimise the risk of

potential bacterial growth within our expansion vessels?

Ensure that they are installed correctly;

● Avoiding water temperatures between 20˚C and 45˚C

● They are manufactured from approved materials.

● They are mounted vertically (the correct way up) on the pipework to minimise trapping any debris.

● Ensure the vessel is fitted with an isolation valve and drain valve to aid flushing and sampling.

● They are mounted as close to the incoming water supply as possible.

● Vessels must be installed exactly as per the manufacturer’s instructions.

● Designed to minimise the volume retained within them.

● Design should be considered to achieve maximum flow through the vessel.

● Flow-through vessels should be fitted where appropriate.

● Regular checks should be made on the vessel to ensure it is operating correctly.

HTM04-01 Part B Section 7.39 recommends;

Pressure and expansion vessels should be subject to routine inspection and maintenance as recommended by the manufacturer. These should be flushed through with wholesome water and purged to drain where practicable. If replaceable, bladders or diaphragms should be changed according to the manufacturer’s guidelines.

HSG274 Part 2; 2.39 and Table 2.1 make the same recommendations;

Where practical, flush through and purge to drain. Bladders should be changed according to the manufacturer’s guidelines or as indicated by the risk assessment.

Other considerations

Some products currently available can be retrofitted to convert a standard single connection expansion vessel into a 'flow through type' by diverting a portion of the flow into the vessel so that the water is continually renewed.

These are known as anti-Legionella valves, and if a WRAS-approved valve is used and installed correctly it can help mitigate potential stagnation.

Under the Health and Safety at Work Act 1974 and in compliance with ACoP L8, HSG 274, and HTM04-01, duty holders, including employers and those in control of premises, must identify any potential risk (this includes Legionella and other water-borne bacteria) and implement a control regime to protect their employees or others that may be affected.

As with any risk, the first consideration should be elimination. Consider changing out old-style vessels with a suitably sized

alternative flow-through design. This is usually relatively inexpensive to do, although the work should be carried out correctly, as per the manufacturer’s instructions, and in line with current Water Regulations.

ACOP L8 Para 78 states:

“Anyone involved in the supply of water systems (designers, manufacturers, importers, suppliers, and installers) must, as far as is reasonably practicable, ensure that the equipment is designed and constructed so that it is safe when used at work and enable safe and easy operation, cleaning, and maintenance”

ACOP L8 Para 80 – b states:

“Aid safe operation (e.g., without dead legs, or if this is not possible, limit the length of dead legs and disconnect or remove redundant or non-essential standby plant).

Conclusion

Expansion vessels are an integral component of water distribution systems. As discussed, there are various types, and each, on its own merits, may need different maintenance and Legionella management protocol. When installed correctly and serviced with an appropriate maintenance regime, the potential for the proliferation of Legionella bacteria within an expansion vessel can be greatly reduced.

WORCESTER BOSCH LAUNCHES GREENSTAR1000

Enhancing its range of heating systems, Worcester Bosch has launched the Greenstar 1000. The latest addition to its boiler range features much of the DNA found in the company’s well-known Greenstar range but at a lower price point. The company says the new solution has been, “designed for consumers where price is their number one consideration.”

The market has changed due to the cost-of-living crisis and Worcester Bosch says that it has designed this “ultimate budget boiler” with that in mind.

Installer friendly

The company says that careful consideration has also been given to the installer, from the initial installation process to after service. The Greenstar 1000 has a one-box design and with its compact size itis suited for kitchen cupboard installations where space is at a premium.

It has been constructed to weigh 26kg making transport, mounting and installations convenient. The new boiler comes with a five-year guarantee.

SANIFLO DELIVERS FOR NEW DENTAL SCHOOL

Saniflo UK is providing two 610 Sanifos lifting stations and a Sanivite grey water pump to a new, state-of-the-art dental school in Bristol. The first of the Sanifos 610 lifting stations takes the water from a 20,000-litre booster tank in an adjacent plant room during routine maintenance and cleaning. It also provides an overflow for excess water. This is pumped up to street-level drainage directly above the unit.

The second Sanifos 610 is situated directly beneath the clinical rooms and takes waste from compressed air and suction drainage tools used by trainee dentists. The condensate waste from several air handling units installed in the same basement section, but on a higher elevation, is also discharged into this Sanifos, which again pumps the waste up to the mains drains.

A third unit, a compact Sanivite+ grey water lifting station, was specified to take wastewater samples once per week from side stream filters that monitor the heating and chilling systems throughout the whole building. Water is frequently tested, and the resulting wastewater is pumped out through the Sanivite+ to mains drains. This automatic operation is designed to ensure there is no rust contamination in the pipework to maintain the optimum efficiency of the temperature controls.

Nathan Thomas, Senior Mechanical Engineer at Briggs and Forrester Engineering Services – the company appointed by Kier Construction to complete the fit-out of the building – oversaw the installation of the units. He said: “Saniflo products are robust and durable and we know we can rely on them to do a good job. The support from the Saniflo team is always exceptional, whether it’s a site visit or a technical phone call, and the units are easy to install and maintain. They solved our drainage challenges at the dental school with ease.”
