Has the UK gas boiler market got a future?
As the government looks to meet its carbon reduction targets, the UK domestic heating market is likely to change significantly – so is there a future for gas boilers? Martyn Bridges from Worcester Bosch looks ahead.
It’s no secret that there is an end of life in sight for the gas boiler. There is talk, but as yet no absolute policy, that by 2035 the natural gas we use in our homes and offices today will no longer be available. At the time of writing, some newspaper headlines have suggested that Boris Johnson may extend this until 2040.
Whatever the date, our commitment to net zero means that there will come a time when natural gas will no longer be used in our homes. However, there is hope for the gas boiler because it can continue to be installed if we transfer from natural gas to hydrogen. This may also be the case for LPG too.

End of the road?
By 2050, a number of things need to happen. One assumption is that we should stop using gas boilers altogether and replace them with alternatives such as heat pumps or heat networks.
Yes, there are occasions and instances where that could happen, but most are quite impractical, and relatively expensive.
There are currently an estimated 24 million homes with gas-fired boilers. A high percentage of those would be unable to function without at least severe disruption if the boiler were no longer in situ. The alternative would be similar to unleaded petrol where they ‘greened’ the gas – in this case with hydrogen.
Blended sites
Trials have been underway for several months now to help identify the best heating solution using blended gas as we aim for net zero.
The Keele University trial commenced in October 2019, with a blend of hydrogen and methane gas delivered to 100 homes and 30 University buildings. Up to a 20% blend of hydrogen was injected into the gas grid and fed these 130 properties, amounting to around 150 boilers fitted, with more than one boiler in larger properties. The trial has successfully demonstrated safe hydrogen blending works, for cooking, heating and hot water on campus.
Another trial in Gateshead has 669 properties on site, all of which are residential, occupied properties which have been isolated from the main grid for injection of up to 20% hydrogen. Physical equipment has been installed on site in the shape of hydrogen storage facilities, while engagement has been undertaken with consumers and the industry generally.
The safety case for the trial has already been submitted to the HSE for review, and as a result we expect to see more blended sites in operation.
Hybrid systems
Hybrid heating systems could well represent the best solution to help meet the existing boiler needs in homes across the UK. A hybrid is a combination of a boiler that could be gas, oil, or LPG, running in tandem with a heat pump, which is generally a smaller output heat pump.
A heat pump tends to serve the heating system for approximately 70% of the time that the heating is required. For the colder periods, the boiler can contribute to this, but it is generally a heat pump-led system.
If this combination gets installed, we will decarbonise significantly, and one of the benefits of a hybrid system is that there is little or no change needed to the existing heating system, so the disruption to the property, which you would have to experience generally with a heat pump installation, is lessened or even eliminated.
Combi boilers
This installation would also help significantly with the high proportion of combi boiler installs that we have. We believe that there are around 17 million combi boilers installed – so that’s 17 million homes without a hot water storage cylinder. A hot water storage cylinder is vital for the operation of a heat pump.
If we can continue to use a combination boiler to generate hot water and to top up the heating system in extremely cold periods, but support this with an installation of a heat pump, then that is likely to be far more accepted in people’s properties, as disruption is kept to a minimum.
Heat networks
An alternative to the challenges that we are facing with heat network schemes will be the use of hybrid systems to get good decarbonisation levels. If you have 40% of the heat load covered by heat pumps, then you can cover an excess of 80% of your kW hours. This means that 80% of the energy is going across to a renewable source, which will be a way to achieve a reasonable level of decarbonisation on some of these harder-to-achieve schemes.
The main benefit of including a hybrid system instead of a sole heat pump is that it can support future carbon emission reductions. It is looking increasingly likely that current boilers will be hydrogen-ready appliances in the coming years, so much so it could become a mandatory requirement.
Heat networks typically operate below 25% of their peak demand for over half of the year, which is why heat pumps are well-suited to larger schemes. By having peak-load boilers on standby, and introducing a hybrid heat network, when the outside temperature drops to its coldest during the winter months, the hybrid heat network will provide end users with instant peak time hot water and heating.
Balancing act
To conclude, there is not an all or nothing situation at hand when it comes to the future of gas boilers.
We will not see the exclusive adoption of either heat pumps or hydrogen across the UK, however what is needed is finding that balance between the two types and promoting a mixture between them as we move away from gas-fired boilers in the future.
The future for boilers is still there, it will likely reduce in size, but ultimately it will still be a very buoyant market, however using green gas as opposed to natural gas. ◼ phamnews.co.uk/1021/24
How to optimise heating effi ciency
At a time of rising energy prices, research suggests that many installers could be doing more to ensure their customers’ gas boilers and central heating systems are working as effi ciently as possible. Darren McMahon from Viessmann provides some useful tips on helping customers to reduce their heating bills.
You’ve probably seen the news stories warning that big rises in gas prices are on the way, with wholesale energy costs having rocketed by 50% in the six months to August. Even without climate crisis concerns, it’s therefore more important than ever for the industry to maximise the energy effi ciency of customers’ gas boiler heating systems.
Yet recent research by the government into the implementation of Boiler Plus regulations, which aim to reduce energy consumption, would suggest that effi ciency measures, whether mandated or not, are not always front of mind. The survey reports that installers have a broad awareness of the rules, but not all have detailed knowledge. As a result, many installers simply fi t one additional Boiler Plus measure – most often smart controls – as a matter of habit, whereas it would be better to think about the most appropriate measures for each household.
With legislation only likely to increase and with the growth of renewables, smart heating businesses will already be thinking of themselves less as gas fi tters or heating engineers and more as climate solutions companies. However, if ever there were a time to look for ways to optimise energy effi ciency when specifying and installing boilers, it is now. Here then are a couple of checklists to help in the quest. One list identifi es technical product features worth searching for when specifying

boilers, the other highlights suggestions for installation and servicing.
What to look for
Weather compensation controls:
Sending the boiler information about temperature changes outside the building and altering radiator temperature to compensate is much more effi cient than waiting for room thermostats to detect that the inside of the building has become too hot or too cold. This alone can cut gas consumption by 15%.
Boiler modulation:
It’s easy to forget, but higher modulation results in fewer burner starts and better effi ciency.
Dynamic pause time
optimisation: By matching pause times after each operating cycle to the rate at which the boiler water temperature increases, the number of cycles and prepurge phases is reduced. And because average boiler water temperatures are low, standby losses are also lower.
Automated combustion control:
Technologies such as our Lambda Pro give the boiler a better ability to modulate down – for example, the Vitodens 200-W modulates down to 1.8 kW with an impressive turndown ratio of 1:20 – improving effi ciency. It also adjusts the gas/air mixture to compensate for fl uctuations in gas quality, ambient air and atmospheric pressure, to maintain constant effi ciency and improve wear and tear.
Burner effi ciency:
By regulating burner fl ame intensity with exceptional accuracy, and having a modulation range of 1:17, our MatriX stainless steel cylinder burner’s effi ciency rate is a high 98%.
Weather compensation controls can reduce gas consumption by 15% The Viessmann Vitodens 222-F condensing combi boiler comes with a 100 litre DHW cylinder
Remote monitoring:
Software such as our Vitoguide mobile app allows installers to receive automated messages and fault displays for remote maintenance. They can quickly solve issues that might otherwise continue unnoticed and reduce boiler effi ciency. Likewise, customer apps make controlling energy consumption much easier.
Central heating pump:
Most domestic boilers include a DC speed controlled pump, automatically saving energy; however in larger and commercial systems, which have external pumps, DC is better than AC and AC pumps can be updated. Rather than guessing what’s best, it’s important to consider each individual building’s boiler output, piping layout, and insulation in order to reduce electricity usage.
Low-loss headers:
It’s important that this performs properly. By acting as a hydraulic separator, decoupling the boiler and system circuits from each other, it increases operational effi ciency and can prolong the life of the boiler or components.
What to do
System fl ushing and cleaning:
Essential when installing a boiler or an entire system, because closed-circuit heating systems lose effi ciency when circulating water is contaminated by particulate debris and sludge. Heating the fl ushing water to 40°C will enhance the loosening and suspension of debris.
Hydraulic balancing:
Many homeowners fully open both valves on every radiator, thinking it will give them more heat, but this can deprive radiators furthest from the boiler of adequate hot water fl ow, meaning that systems often need balancing.
Insulate condensate pipes:
If they are uninsulated they are at risk of freezing over. Internal condensate drainage pipework must be a minimum of 19mm internal diameter, should fall at least 45mm per metre away from the boiler, and increase to 30mm internal diameter before passing through the wall to the outside, where pipes should be insulated.
Annual servicing:
If a boiler isn’t serviced as often as the manufacturer recommends, it will gradually lose combustion effi ciency and become vulnerable to breakdowns. This is worth mentioning to customers, who might not understand that stretching service intervals is a false economy.
It is also worth briefl y describing to customers the key measures that have been taken to ensure their heating system is performing with optimum energy effi ciency. ◼ phamnews.co.uk/1021/25
While anyone working in the plumbing and heating industry will be well aware of the need to service boilers on a regular basis, the general public may be less aware of the importance of doing so. Left unchallenged, this disconnect could cause serious issues over time, such as reduced effi ciency and even a complete breakdown. Therefore, communicating the reasoning behind why servicing is vital, not only from a safety perspective but also from a cost point of view, is worthwhile.
Asking questions
As more people will have been at home over the past 18 months, any changes to their heating system, such as radiators not warming up effi ciently or a lack of hot water, are more likely to have been noticed. Talking to customers and asking questions about how their hot water and heating has been performing can help to identify if any adjustments are required in order to ensure safe and effi cient operation.
There has also been a surge in home improvements during lockdown, most likely as a result of householders spending more time considering the work that may need undertaking in their properties. Whether this involves extending the space available by building an extension or revitalising the bathroom, these changes could have an unexpected eff ect on their heating system.
Flue positioning, for example, is carefully thought through by heating engineers. However, when carrying out construction
Helping customers to stay warm this winter
As the colder months draw in, homeowners will once again be looking to their boilers to keep their homes cosy and warm. Chris Riley from Baxi takes a closer look at some of the key areas installers might wish to consider when giving their customers advice on how best to ensure that their gas boilers remain in tip top condition.
work, people are all too often unaware of the requirement for a fl ue to be correctly sited in accordance with regulations. It’s simply something they would never think to check with their installer. Incorrect work in this area can lead to poor or restricted eff ectiveness of the fl ue, and even in extreme situations complete blocking of a fl ue outlet or air intake. To prevent this from happening, encouraging customers to get in touch when considering renovations is key. Similarly, educating them on the impact of adding anything requiring a supply of hot water, such as a shower, radiator or extra sink, may help to avoid pressure or supply issues.
Remaining vigilant
Ensuring customers understand what signs are a cause for concern is just as crucial as encouraging them to share information about planned home improvements.
Visually checking the boiler and hot water cylinder, as well as the areas around them, could indicate if something is not right. Throughout the year, homeowners can easily keep an eye out for any obvious areas of concern like leaks, staining,

scorching or a fl oppy yellow fl ame on gas fi res or cookers. Explaining the signifi cance of these tell-tale signs helps to highlight potential problems as early as possible, giving heating engineers the best chance of resolving them quickly.
Warranty conditions
Many households may be unsure of where they stand with servicing and whether or not their boiler is still under warranty, especially given the disruption caused by Covid on regular checks.
While boilers must be serviced annually to remain within warranty, allowances were made in 2020 and 2021 due to lockdown, so having a conversation about the impact of this is useful. If there is any doubt about whether or not a warranty is still valid, you can check with the manufacturer. Our team at Baxi are always happy to help.
To provide further protection, it is recommended that a fi lter is fi tted with every boiler as per guidance in BS 7593. This is a mandatory requirement of the 10-year warranty for the popular Baxi 800 range, which comes with an Adey Micro2 magnetic fi lter in the box. Looking ahead
Giving homeowners the knowledge necessary to ensure their heating system is running as effi ciently and safely as possible benefi ts everyone. It increases the likelihood of faults being identifi ed earlier or avoided altogether, reducing the amount of time needed to resolve the situation.
When servicing any Baxi boiler, we recommend that heating engineers refer to the appropriate installation and service manual for the type and model, which provides detailed instructions and combustion performance fi gures. This information is available free of charge online for nearly all older appliances, as well as the newer models – especially useful if the guide is missing from the home.
Finally, they should always point households in the direction of the Gas Safe Register website to check safety alerts. It pays for everyone in the industry to promote this resource all year round, as more homeowners are aware that the Register exists, the more people will know to check the credentials of their chosen engineer. ◼ phamnews.co.uk/1021/26
CUT TO THE CHASE

decade and, as a result, demand for these heating stalwarts is showing little sign of slowing down – Sean Keleher, Navien’s technical manager, explains more.
The humble gas boiler remains at the heart of many UK homes – and it looks set to remain this way, with the Energy & Utilities Alliance (EUA) reporting an % increase in demand year-on-year. Indeed, the latest EUA report states domestic boilers were at their highest June volume since , which is great news for the heating sector as a whole.
Given this level of demand, what should installers be looking for when selecting a customers the best in heating technology? Let’s consider a few of the fundamental parts in more detail.
On display
It might seem the obvious place to start, but a boiler’s display is often overlooked. Modern, touch screen displays are key, especially in terms of ensuring a unit is user-friendly. Plus, from an installer’s display will provide quick access to the details required for accurate and precise levels of servicing. The latest models ensure and return temperatures, as well as system water pressure.
The type of displays found on condensing gas boilers, such as our own NCB units, also allow installers to test some components including the fan, pump and combi diverter valve, while an extra test for the gas venturi is available. All this information is essential when it comes to ascertaining the Benchmark information required during commissioning and servicing, which must be carried out in accordance with the manufacturer’s instructions. It also helps compliant with the necessary Building Regulations.
Heat exchanger
When looking to ensure a boiler has a long lifespan without losing either performance of the heat exchanger is crucial. A vital component of any gas boiler, the heat exchanger is required to operate in a harsh environment, where it is subjected to various thermal and mechanical stresses. It also has to contend with any impurities in system water, as well as dissolved oxygen
The most dependable heat exchangers are made from stainless steel because not only does this material excel in a wide level of resistance against corrosion. Its ability to operate in a wider scope of pH values reduces reliance on chemical water treatments, while maintaining high levels
Control system
Manufacturers have also made great strides in the development of heating controls, to ensure the latest devices are of the same high standards as their gas boilers. In fact, the savviest companies have ensured that heating systems pairing their boilers and
The concept spans far beyond the reaches of simply integrating controls into the boiler itself, thanks to advances in wireless technology and the evolution of ‘smart’ devices. Manufacturers’ own control units, such as our innovative Smart Plus, can overall ErP rating to ‘A+’. These controls also provide a number of advanced and energy-saving functions, such as weather compensation, which accurately adjusts to external conditions, thereby reducing energy consumption and costs.
Of course, modern smart controls also appeal to tech-savvy end users, especially when they can be accessed via a smartphone app. Not only does this allow remote access and adjustment of the heating and hot water system at the touch of a button, there is also the capacity to receive error messages or useful features such as geofencing, where a person’s proximity to their home dictates how the heating system operates, with the how close (or far away) someone is to their property. This can even be set up across multiple handsets, enabling all members of a household to enjoy their preferred indoor temperature.
Now, if a gas boiler is to perform to an optimum level, it is imperative that the terms of safety, it also has a role to play when installers are assessing a boiler should not be overlooked. determine its maximum allowable length. This has led to us utilising the Ø / either horizontally (through the wall) or vertically (through the roof) – although the distance by which they can be extended determined by the ability of the boiler itself. extend to around - m, at Navien we can -leading lengths up to m for a is due to our heat exchanger design and a powerful fan, which can provide the long applications.
Smart choice
So, it is plain to see that thanks to the many advances in technology, the gas boiler is set to remain a key player in the heating sector for the near future. By choosing products controls technology, emissions can be kept to a minimum – as can end users’ energy bills. Installers just need to make the smart the excellent levels of performance their customers deserve.

Low carbon heating under computer control
As gas prices soar and with little prospect of the cost to homeowners coming down any time soon, if ever, Oliver Baker from Ambion Heating makes the case for computer controlled infrared (CCIR) heating systems.
Over the last 12 months, we have seen several important pieces of government policy and strategy that all point to one common fact - if we are going to hit the UK’s net zero target by 2050, it will require the mass electrifi cation of many aspects of our lives. From vehicles to heating, new electric technologies will be crucial to our decarbonisation success.
This is particularly true when it comes to ‘greening’ the UK’s housing stock. For new builds, there is a clear deadline that properties should be ‘zero carbon ready’ by 2025 under the Future Homes Standard. For existing properties, there is a major retrofi tting job to do. The Climate Change Committee estimates that out of 29 million homes in the UK, 19 million have an EPC lower than ‘C’. In the Energy White Paper, published at the end of 2020, the government reiterated its commitment that all UK houses should be EPC Band ‘C’ by 2035.
We fi rmly believe that one of the biggest solutions to the decarbonisation problem will be electric heating systems. And, while the headlines have been on air source heat pumps (ASHP), in reality, it will take a broad range of technologies to meet the government’s ambitious targets.
So, how can electric heating technologies help meet sustainability standards for both old and new builds?
Cost eff ective
One of the main arguments against electric heating is the cost when compared to gas, largely due to the higher unit cost of electricity.
However, there are technologies available now that are making electric a much more aff ordable and viable option, even when budgets are tight. One of these is computer-controlled infrared (CCIR) heating, which has several benefi ts for installers and their customers, as it is both low carbon and tackles the issue of cost when it comes to electricity vs gas.
CCIR uses infrared which is a high performance way of delivering heat using less electricity than conventional electric heating. What makes CCIR diff erent is that it also uses software with each panel, which constantly monitors each individual room and the energy storage characteristics within it, adjusting its energy delivery routine to maintain the ambient temperature within the room, maximising its performance and using fewer units of energy than a traditional heating system.
The resulting savings are compelling. We commissioned an independent performance review of CCIR to assess how it compares with both traditional convection systems and ASHPs. It revealed that CCIR provides the same levels of comfort within a room, using 60% less energy than a standard electric convection system and on a par with ASHPs.
The system also reduces the unit cost of electricity because it works best across 24 hours. This fl at demand profi le - there is no morning or evening energy spike in usage - also means that if a homeowner is on a fl exitariff , CCIR can achieve around a 25% saving in the unit cost of your energy. So, if you put those two things together – the 60% reduction in electricity usage with the 25% saving on unit cost – the running cost is comparable with gas.

Time saving
CCIR systems are also easier to install, whether they’re being retrofi tted into an existing building or installed within a new build, because they simply need wiring into the mains rather than plumbing in. Therefore, an installer can fi t the system and move on to the next job in minimal time.
Another benefi t is reducing

the administrative burden of processing warranty claims. For example, unlike AHSPs, CCIR has no moving parts and requires no annual maintenance, so it makes an ideal choice for end user customers who want to ensure that they have minimum after sales issues and warranty claims.
Wide application
Unlike other low carbon solutions, CCIR can be installed in any building that has electricity. While it is particularly suitable for off gas grid properties, given the UK’s targets for switching from fossil fuel heating to low carbon alternatives, housebuilders, landlords, commercial and public sector buildings could all benefi t from the high performance and emissions reductions CCIR provides.
To help installers prepare for the low carbon heating transition, we are working in partnership with several contractors across the country to train them on CCIR, its benefi ts, and how to install it. For us, working together with installers, developers, landlords, contractors and builders is crucial if the road to net zero is going to be a success.
The future of heating has to be low carbon and we believe electric systems will play a transformational role. Therefore, for installers, demonstrating an expertise in installing the latest low carbon electric heating systems, like CCIR, could be a key diff erentiator when it comes to winning contracts. ◼ phamnews.co.uk/1021/35
Quick and easy ways to deliver hot water
Around 12% of an average home’s energy consumption is for heating water, and while the amount depends partly on how much hot water is used, the type of water heater has a huge bearing on both cost and green credentials. With this in mind Richard Harvey from Wolseley Plumb & Parts looks at the potential of electric water heaters.
Driven by both consumer demand and space constraints, the combi boiler has taken the market share in new build properties in recent years. This trend looks set to change, with the government’s Future Homes Standard banning all fossil fuel heating from new build homes from 2025. In response, housebuilders are exploring a range of options, such as ground and air source heat pumps. However, as the market evolves, electric water heaters are growing in popularity, off ering a solution that lowers emissions and off ers a viable alternative to gas.
Evolution
Traditionally a functional piece of kit hidden away, electric water heaters are evolving to become more aesthetically pleasing, with some even designed to complement and add to the interior design. For smaller homes, water heaters off er a space saving solution versus traditional cylinders or boilers. Slimline wall-hung solutions take up far less space than a cylinder in an airing cupboard. Instantaneous water heaters off er the most compact solution, while larger capacity storage water heaters also come in compact packages, with slimline versions off ering suffi cient hot water for a small household to have a bath or multiple showers.
While the regulatory environment might account for a shift towards electric water heaters as a more sustainable choice for new builds, the pandemic has also resulted in a change in the way we use our homes. With home offi ces on the rise, water heaters can provide an ideal solution for those looking to access hot water in their converted sheds, garages and annexes. The pandemic has also seen an increase in multigenerational households. In these situations, water heaters are the ideal way to add extra capacity quickly, and at a relatively low cost, without having to worry about exceeding the capacity of the boiler or extending gas pipework.

Electric water heaters can be real space savers, discreetly tucked away under the sink or in a cupboard
thermostat, with smart heating becoming commonplace in the nation’s homes. Electric water heaters are just starting to tap into this trend.
Making a connection
Today’s water heaters feature intelligent controls which give users a simple, fast and effi cient way to control their heating and water supplies. Many also have the ability to link systems to a smart phone app, allowing users to start, stop, monitor and adjust the temperature of their water, tweaking settings to improve effi ciency and save money. Ariston’s eco-evo function takes smart functionality one step further. This highly intelligent tech eff ectively memorises water consumption habits and manages the water temperature autonomously, ensuring that hot water supply meets demand when required.
For installers, being able to upsell smart-tech products is one way to meet growing consumer demand. However, some systems on the market also off er the added benefi t of being able to use the app for fault fi nding, allowing installers to assess the scope of the job and ensure they have the right parts to hand before they arrive on site.
Water heaters come in all shapes and sizes, with key diff erences making them suitable for diff erent applications. Instantaneous water heaters deliver hot water immediately at the point of use. When a hot water tap is turned on, cold water travels through a pipe into the unit, where an electric element heats the water. With no standby energy losses and no need for fl ues or gas piping, these systems are a good choice for properties with minimal hot water requirements or remote areas of the home. Industry leading brands, including Ariston, Heatrae Sadia, Santon and Triton, off er a range of wattages as well as multipoint specifi cations to fi t the needs of the application.
Higher demands
For those with a higher demand for hot water, properties with up to three bedrooms, or light commercial applications, storage water heaters off er increased hot water availability. Products such as Ariston’s Velis Evo range is available in 45 and 80-litre capacities, with titanium enamelled twin tank technology with separate heating elements that ensure more hot water is available when required.
Rule and regulations
For installers, the most important thing to note is the diff erence in the way that these units are installed. Installation of units under 15 litres will require a knowledge of G3 regulations. However, those over 15 litres must be hard-wired to the fuse board and require the services of an electrician - an important distinction to make. Installers looking to tap into this growing market should make sure that they carry a BPEC G3 Unvented Certifi cate/ identifi cation card, enabling them to prove that they possess the relevant skills required to comply with regulations.
For systems over 30 litres, it is important to consider the need for an expansion vessel, to help maintain pressure, handling the expansion and contraction of water as it heats and cools; a non-return valve to prevent backfl ow of any hot water into the cold mains; and a discharge tundish, which provides a visual indication of over pressurising and prevents any water from being sucked back due to high pressure. While smaller systems may be DIY projects, it is important that installers educate customers about the benefi ts and legalities of using a professional. ◼ phamnews.co.uk/1021/36
Energy storage made easy
- - when it’s needed – so says Jason Hobson, McDonald Water Storage.
With the ambitious target to remove gas from new build homes by , there has been much deliberation over technologies such has hydrogen ready boilers, heat pump technology and solar PV or solar thermal to help achieve carbon reduction targets.
However, the application of these technologies in some new as multi-occupancy developments or high-rise apartments, is not always feasible. This has led to forward thinking developers and housing management companies already looking towards all electric systems to provide a installation solution.

Thermal stores use the electricity not just as a backup but as the main heat source to enable the load shifting of energy demand. This provides a fantastic opportunity in apartments where the switch to electric is required, enabling the costs to be competitive with that of a traditional gas system.
It is important to understand that the thermal store is not just a hot water cylinder, but an energy store. Therefore, when sizing the thermal store, the kW requirement for the property needs to be taken into account so that the load shifting potential can be calculated.
For example, where a property has an annual requirement of kW for heating and hot water, a -litre thermal store is able to hold kW of energy. This enables the store to fully -peak period, load shifting the energy use to the lower cost periods to satisfy the average daily energy requirement of the apartment. By increasing the store size and safely increasing the temperature within the store, additional energy -peak periods to meet higher heating demands without an on-peak boost requirement.
By taking advantage of the - the thermal store allows the homeowner to take the power required at times of lowest cost, therefore saving on the largest portion of their energy requirements.
Flexible Solution
Historically, homes have been restricted to either standard electricity rates or cheap rate -peak periods, but with higher daytime rates. With the increased demand for electric, providers are not only looking electricity generation, much of which is now being produced from renewable energy sources such as wind and solar power. This means when wind and solar generation are at their peak, not only is the carbon intensity reduced but also wholesale electricity costs are at their lowest, making it the best possible time to store energy at home, for use at other times during the day.
This has led to the emergence Agile, which provide another alternative through dynamic pricing, enabling you to load shift your electricity use to when the cost is lowest at any time during the day or night.
Products such as our ELECTRAstore, a bespoke application, can monitor, regulate and manage the amount of energy delivered into the thermal store, providing a smart control device to select the cheapest the store. This method of load adoption of renewable energy sources, helping to smooth out peak loads and maximise the use of environmentally friendly electricity.
Unlike overnight storage heaters, which lose heat through the day, thermal stores deliver energy directly to a wet central heating system, meaning that homeowners can use the heating when they need it most with very little heat loss. phamnews.co.uk
Simple and effi cient way to heat water
Electric water heaters are increasingly being recognised as an energy effi cient solution for a variety of applications. Victoria Gutierrez from Ariston looks at the reasons for this growing trend.
With around 12% of an average home’s energy consumption spent on heating water, careful consideration is required when identifying the products most suited to the application in hand. The amount of energy consumed depends not only on how much hot water is used, but also on the type of water heater installed. While gas water heaters remain a valid option, electric water heaters are becoming more widely installed, especially in off -gas areas, extensions and standalone buildings.
Research has revealed the electric water heater market in the UK is set to experience signifi cant growth in the next fi ve years, with both the residential and hospitality sectors identifi ed as key drivers for this upturn. Of course, Covid-19 remains the elephant in the room; however, while this has aff ected the hot water heater supply chain, it has also contributed to heightened demand for products. Increases in hand washing, bathing and improving general hygiene has seen point-of-use water heating units become essential items – a trend that is likely to continue even as we enter a post-pandemic world.
Why go electric?
Electric water heating systems are quiet, clean and easy to operate, plus they don’t emit any harmful greenhouse gases or nitrogen dioxide. There are a number of diff erent units available, including models that benefi t from conventional tanktype designs, as well as tankless versions suitable for domestic and light commercial applications.
So, when – and why – is electric the best option? According to the Energy Saving Trust, there are four million households across the UK off the mains gas grid. These properties require an alternative means of water heating – and electric systems are one of the most popular options available for off -gas homes and applications without alternative

KEY BENEFITS
Residential and hospitality sectors are expected to see increased use of electric water heaters in the next fi ve years Use of smart technology in electric water heaters can boost energy efficiency credentials The latest models are required to adhere to environmental legislation such as the ErP
Modern heaters also have space saving benefi ts They can help landlords meet minimum effi ciency standards
energy supply. After all, the products are simple to install, requiring only a connection to the electric circuit and mains water supply (plus any required safety devices). Units need little maintenance and are extremely effi cient, as there are no heat losses between the power source and the water output.
From an effi ciency perspective, modern electric water heaters excel, because all the energy they use is converted into heat for the water. Electrically powered units heat water by using coiled elements to maintain a pre-set temperature, thereby minimising energy wastage and maintenance requirements.
Advances in ‘smart’ technology, particularly controls, have further boosted the energy effi ciency credentials of electric water heaters. Some models, including our own Velis Evo Wi-Fi, now benefi t from built-in WiFi, enabling units to be set and activated remotely via a mobile app (such as our Aqua Ariston Net).
This precise level of controllability ensures there is always enough hot water ready when required. Such advanced functionality also allows users to monitor their energy consumption, as well as reduce fuel bills, which is especially important in low-income homes and rental properties.
Landlords’ concerns
On the subject of the rental sector, energy effi ciency is a key consideration for UK landlords, as they must make sure properties are safe and fi t for habitation by their tenants. Landlords are responsible for ensuring all gas and electrical equipment – including water heaters – is correctly installed, tested and maintained, as well as compliant with the minimum energy performance of an Energy Performance Certifi cate (EPC).
The minimum level of Energy Effi ciency standards (EPC band ‘E’) for domestic private rented properties was introduced in 2018 as part of the Domestic Minimum Energy Effi ciency Standard (MEES) regulations. Not only must landlords disclose the energy rating of a rental property when advertising it, they’re also legally required to show the full EPC to potential tenants at a viewing. By having the latest electric water heaters installed, landlords can more easily meet the necessary energy standards required.
Electric water heaters off er enhanced energy performance, with the latest products having to adhere to environmental legislation, such as ErP. This can be coupled with other sustainable functions, such as learning from the household’s daily usage, ensuring that water is only heated during the periods when demand is high. The key benefi t here is that units are not left cycling during periods when a property is empty; this could be 9am to 5pm for a typical working week or, conversely, when a commercial building or offi ce is unoccupied.
In addition to their energysaving credentials, modern electric water heaters are also extremely compact, so they can replace cumbersome immersion heaters and cylinders to create more storage space inside a property. The latest products actually eliminate the need for separate cylinders, as any water is actually stored inside each unit.
The Ariston Velis Evo Wi-Fi is suitable for both residential and commercial applications
Sustainable solution
So, as demand for energy effi cient products increases, electric water heaters off er an array of features and benefi ts designed to reduce consumption and fuel bills. The latest control options also enhance usability while adhering to all necessary legislative requirements. With the electric water heater market set to experience signifi cant growth, installers, specifi ers and property developers alike should all be looking to these products to maintain exceptional levels of long term sustainability. ◼ phamnews.co.uk/1021/38

The real McCoy: why genuine batteries matter
Purchasing non-genuine batteries for power tools can have serious consequences. Tony Coleman from Makita explains the issues around these low-quality and even counterfeit products, and how users can ensure they are buying the real deal.
Online retailers and marketplaces have made it simple for everyone to fi nd and buy the products they need quickly and effi ciently. However, it has also made it harder to distinguish between genuine, high quality products and poor quality replicas and counterfeit products. To the end user, many companies selling these replica, or sub-standard, products appear legitimate and often sell through online marketplaces alongside the genuine versions, but at a far lower price. This is not a minor issue: the campaign group Electrical Safety First (ESF) estimates that one in three people in the UK has inadvertently purchased a counterfeit electrical item online.
This is a particular concern when purchasing replacement batteries for tools. In most cases, counterfeit products have not been manufactured or tested to the required quality and safety standards required by law and this can present safety risks to the user as well as damage the machine it is attached to. Therefore, it is important that installers are aware of the risks and how to avoid costly issues.
Ensuring safety
Cordless technology for power tools has made work easier and safer. Established manufacturers will have invested signifi cantly in research and development to produce batteries that are tested to reliably deliver the performance, run times and charge times that professionals require. To achieve the high energy density of modern lithium-ion batteries, reputable manufacturers will precisionengineer these batteries to control charge and discharge current, cell voltage and temperature. They will also ensure their ‘stability’ with rigorous safety checks.
It is highly unlikely that the same level of attention and quality assurance will have gone into the production of very cheap or counterfeit products and as such, they present a serious risk. If the temperature of a lithiumion battery is not controlled properly in its design, a ‘thermal runaway’ can occur, triggering a chain of events that can cause the battery to catch fi re, or in a worst-case scenario, explode.
Tony Coleman
Technical manager at Makita
Online buying makes it harder to distinguish between genuine, high quality products and poor quality replicas and counterfeits
Genuine batteries have been engineered to deliver longer battery life, protect the cordless tool it’s attached to, and ensure user safety Don’t underestimate the technology within the battery’s casing - it serves to prolong the life of the battery and to protect the tool it’s powering
Tool longevity
In addition to the safety issues, using non-genuine batteries can impact the operation and longevity of the machine itself. For example, Makita lithium-ion batteries, cordless tools and chargers include technology that allows all three to communicate in real time.
This exchange of data protects the battery cells against overload, over-discharge, and overheating as well as maximise the life of the product and provide protection against damage. For example, if the controls detect conditions that threaten to overload, overdischarge or overheat either the tool or battery during use, the tool will automatically stop.
Similarly, the charger will detect if the battery is warm when it is placed on the charger and cool it before it begins recharging to help maintain the life of the battery. These functions are not possible with third-party batteries and therefore cheap products can represent a false economy if they do not last or even if they damage the machine they are used with.
Performance
The quality of a non-genuine battery cannot be guaranteed and so may not provide the level of performance. There are third-party batteries available that claim to have the same Amp hour (Ah) rating as genuine products, but without the necessary testing and accreditations in place, they are signifi cantly less powerful.
As a result, run-times and even tool performance may be reduced. To ensure the battery performs as desired, always check that batteries are tested to IEC 61960 (the equivalent to the UK BS EN 61960 standard). This demonstrates that it can deliver the required level of performance and that this has been appropriately tested.
The fi rst indication of whether or not the product is genuine will be the design of the battery itself and the packaging. Manufacturers will often include unique or diffi cult-to-replicate design features on their genuine products. For example, Makita lithium-ion batteries all feature our trademark logo and the STAR connectivity mark. It is therefore important to make sure that these elements are present. Purchasers should also look for spelling errors, variations in the logo design or clear signs of the logo being copied from somewhere, and diff erences in the packaging or images. These can all be signs that the product is not genuine.
Spot the problem
However, these indications are not always easy to see when purchasing online as the seller may have used images taken from elsewhere to deliberately mislead buyers. If the product does not match what is expected when it arrives, then it should not be used. If there is any doubt over whether a battery is genuine or not, Makita off ers an inspection service at its Factory Service Centres.
This issue is one of the key reasons why it is recommended that power tools and batteries are only purchased from a trusted supplier, such as manufacturer authorised dealers and merchants. They will only stock genuine products, so customers can be sure of quality.
In general, buyers should always be wary of products being sold at unusually low prices. There is often a reason the product is cheap, and it follows that if ‘it seems too good to be true’ it probably is. Where products are off ered on well-known online marketplaces, it can give people misplaced confi dence; however cheap imitations are often sold in this way for this reason.
Using a third-party, nongenuine battery can be dangerous to the user, damaging to the machine, deliver poor performance and invalidate most leading manufacturer warranties. It is therefore important to look out for signs that the products may not be legitimate and to purchase only from reputable suppliers. ◼ phamnews.co.uk/1021/46

A cut above the rest
Cutting pipes and various materials is a regular job for installers, so anything that can help make the task quick and easy has to be worth a look. David Barnes, marketing manager at Knipex, highlights some recent innovations.
Over the last year, cutting tools for plumbing and heating installers have been reassessed and redesigned, providing an opportunity for busy installers to make their working life easier.
Pipe cutting, for example, can be particularly frustrating if your tool is not up to scratch – tightening a cutter too quickly or too hard, or not mounting a pipe properly on a cutter’s rollers, can easily distort or damage the pipe.
The Knipex TubiX pipe cutter ( SB) has been designed so much easier. It features the one-hand QuickLock locking mechanism, which allows for independent holding and clamping on the tube, while an easy-to-use push mechanism enables users to quickly adjust to hand.
This cutter is also very comfortable and cutting is easy due to high-quality needle bearings in the cutting wheel and guide rolls. The TubiX cutting wheel, an important part of any pipe cutter, is made of high-grade ball-bearing steel which cuts pipes from - mm with a wall thickness up to mm. A practical quick blade replacement system for the cutting wheel has also been designed into the tool, with a spare wheel stored under the feeding barrel.
Plastic piping
When it comes to cutting plastic piping cleanly without shavings, the Knipex BiX ( ) can be used as an alternative to hacksaws and other types of in one hand and can be used to cut high-temperature plastic drain pipes and empty electrical conduits in no time and with little
The BiX is suitable for unreinforced plastic pipes with a diameter of to mm and a wall thickness of up to mm. The integrated blade unit can be rotated by ° so it’s easy to cut plastic pipes of various diameters with the blade in the middle, or cut sealing sleeves two to three millimetres from the wall with the blade on the outside. The blade can be turned so that surface.
Most installers will carry a work knife in their toolbag, and just like pipe cutting tools, this traditional tool has been revisited by Knipex with new features to make cutting even safer and

Knee pain – why suff er unnecessarily?
Many plumbing and heating engineers believe that knee pain is simply an occupational hazard, but this all-too-common problem can have many consequences. Matthew Handley from ToughBuilt explains why his company is on a mission to protect workers from unnecessary injury.
In an average 47 hour working week, most plumbers and heating engineers can spend around half their time on their knees. This extensive kneeling can have a damaging eff ect, causing prolonged pain and a loss of earnings due to time off work.
Worries about knee injuries are shared by many in the sector. A recent survey conducted by The IPG - the membership group for independent plumbing, heating and bathroom merchants - found that almost 60% of plumbers felt they would need to undergo knee replacement surgery in the future.
Likewise, two thirds of those surveyed felt knee injuries sustained at work would cause them to retire early whilst many stated they have already been forced to undergo physio, keyhole surgery or other operations on their knees as a result of their occupation.
Lost hours
When it comes to knee injuries sustained in the workplace, the facts speak for themselves.
According to Business in the Community, a network established by the Prince of Wales to champion responsible business, musculoskeletal (MSK) problems such as back, shoulder and knee pain are the leading cause of lost working days in the UK. It is estimated they cost the country’s economy an alarming 31 million days every year.
Similarly, research published by the Health & Safety Executive (HSE) in late 2020 highlighted that of the 480,000 work-related musculoskeletal disorders

ToughBuilt off ers a wide range of knee protectors, including: the Rocker kneepads (left) and Stabilizer kneepads (right) (WRMSD) recorded for 2019/2020, some 93,000 aff ected the lower limbs – including the knees.
Given these alarming statistics, it seems hard to believe that knee protection and the mandatory use of items like kneepads isn’t treated with the same importance as the use of other forms of PPE such as hard hats, safety glass and safety boots.
At ToughBuilt we plan to change this, which is why we launched our KneelSmart, KneelSafe campaign earlier this year. We believe that just one knee injury sustained at work is one too many. We also want to help individuals and organisations to avoid falling foul of what is an unacceptably common problem with potentially devastating consequences.
Duty of care
It’s an unfortunate truth that many of us take our knees for granted and only realise how crucial they are to our everyday movement, quality of life and well-being when they don’t function as they should.
Aside from the human costs of knee injuries sustained at work, there are also commercial and legal implications.
As a prime example, the Health & Safety at Work Act 1974 requires employers by law to carry out risk assessments of activities undertaken by their employees. Where a need for knee protection is identifi ed, it is important this is supplied to avoid signifi cant fi nancial penalties and compensation.
Over the years, we have
Our aim is to raise awareness of the risks posed by work-related injuries and of the ways in which they can be prevented.
For instance, as a rule of thumb, we would urge people to always use kneepads at work whenever there is a risk of impact to the knees or of sustained pressure on the joint - for instance from extended periods of kneeling.
acquired an almost unrivalled understanding of kneepads and the very real diff erence they can make in protecting people.
This is amplifi ed by the fact that we design our products from the ground up to off er standardsetting levels of both comfort and protection. This is only made possible by our extensive research into a broad array of related areas such as knee health and ergonomics.
KneelSmart, KneelSafe draws on every aspect of our expertise. It’s a coordinated programme of activity that includes working with the media to produce educational articles, lobbying key industry bodies and policy makers, and working closely with leading authorities such as the British Safety Industry Federation.
Ultimately, the KneelSmart, KneelSafe campaign is driven by a duty of care and by our desire to share our knowledge for the greater good of the industries we serve. What to look for
To choose knee pads which are fi t for purpose and that off er adequate levels of protection, we would also stress the importance of checking for adequate levels of performance in three key areas - penetration resistance, force distribution and shock absorption.
Penetration resistance is measured in levels between 0 and 2 with 2 being the highest. All ToughBuilt Kneepads off er either level 1 or level 2 penetration resistance which is unrivalled in the market. This primarily helps avoid serious injuries which can arise from accidentally kneeling on a nail, stone or other jagged or sharp-edged surface.
Perhaps the simplest way of doing this for both individual and volume users, as well as for retailers and distributors, is to always opt for kneepads that carry CE or the new UKCA markings, or that are certifi ed to relevant standards such as BS EN 14404.
Just by having an awareness of the dangers and by following these simple steps can be suffi cient to prevent you or someone else becoming another unfortunate, work-related knee injury statistic. ◼ phamnews.co.uk/1021/53
