Rise in renewables
Recent data has revealed the number of Heat Pump and Solar PV installations that took place in 2024. Installations of these ‘small scale renewables’ (which also include battery storage) rose to more than 260,000 certified installations, according to data from MCS (Microgeneration Certification Scheme). The total number of certified installations, it says, have now passed the two million mark.
MCS has suggested this highlights, “the nation’s growing commitment to renewable technologies.”
As far as Heat Pumps go, MCS data indicates that 2024 saw almost 60,000 certified installations – a 43% increase on 2023, bringing the total number of certified heat pump installations in the UK to over 275,000. You can read more on this story on page 6.
Further data on the year, this time from the Heat Pump Association (HPA) tells a similar story. It reports there was a 63% increase in hydronic heat pump sales in 2024.
The organisation’s Chief Executive, Charlotte Lee, has called 2024 “a pivotal year” for the heat pump market in the UK. You can read more on this story on page 8.
Undoubtedly, the market for heat pumps and other renewables has grown significantly in the last couple of years. Many heating systems manufacturers now offer Heat Pumps within their portfolio and the types of systems available are also expanding; alongside other models, many companies now offer Heat Pumps utilising the R290 refrigerant.
Importantly, it appears that installers are also increasingly interested in gaining a qualification to fit Heat Pumps. Along with an increase in sales, the HPA’s data for 2024 also reported a 15% increase in individuals completing a recognised heat pump training qualification. Alongside the training required to install Heat Pumps, there is also a lot of specific product training becoming available from manufacturers. For example, Ideal Heating has recently announced an expansion of its Expert Academy On-Demand platform. New digital training courses on the platform include product training for both the Ideal Logic Air and HP290 air source heat pumps. You can read more on this story on page 41.
Although growing, the market for Heat Pumps remains far smaller than that for Boilers. Whilst the pace of adoption in the coming twelve months remains to be seen, it is clear that 2025 will be another important one for the technology.

DEVELOPMENT OF NEW LEVEL 2 AND 3 APPRENTICESHIPS FOR PLUMBING APPROVED
The Chartered Institute of Plumbing and Heating Engineering (CIPHE) has gained formal approval to develop new Level 2 and Level 3 plumbing apprenticeship standards from the Institute for Apprenticeships and Technical Education (IfATE).
Last year the CIPHE conducted an Education Survey in which it found that 90%* of respondents were supportive of a proposal to introduce both Level 2 and Level 3 apprenticeships. The Level 2 Standard will allow apprentices to complete an End Point Assessment covering topics such as hot and cold water installations, as well as sanitation and rainwater systems.
Successful completion of a Level 2 apprenticeship in plumbing will provide learners with a wide range of options for Level 3 progression. This will include low carbon heating, gas engineering, and the plumbing focused apprenticeship that introduces further assessment on advanced hot and cold water, low temperature hot water heating systems and plumbing/heating systems design.
Kevin Wellman, Chief Executive Officer at the CIPHE, said: “IfATE’s approval of the proposal to develop Level 2 and 3 apprenticeship standards is a vital development for our industry. While we are delighted at their approval of our work to date, this is not the end. The crisis in plumbing education means that the CIPHE aims to have the new apprenticeship up and running as soon as possible, and our work with plumbing employers and relevant stakeholders to ensure the Apprenticeship Standards will be fit for purpose both now, and in the future only increases from here.”

RECORDYEARFOR UK HEATPUMPSALES
New data from the Heat Pump Association (HPA) reveals that 2024 saw a 63% increase in hydronic heat pump sales, and a 15% increase in individuals completing a recognised heat pump training qualification.
The HPA’s data shows that 98,469 hydronic heat pumps were sold in the UK in 2024. This growth is largely driven by a 64% increase in Air to Water Monobloc sales and a 100% growth in the ‘other heat pump’ category which includes Domestic Hot Water Heat Pumps, Exhaust Air Heat Pumps and Integrated Hybrid Heat Pumps.
The HPA says it is encouraged by this growth, which has been supported by Government schemes such as the Boiler Upgrade Scheme and the Energy Company Obligation with MCS heat pump notifications accounting for 60% of total sales. It says that to meet demand, growth in sales must be accompanied by a growth in the skilled heat pump workforce. 2024 saw 9,062 individuals completing a recognised heat pump training qualification – a 15% increase on 2023 levels.
Charlotte Lee, Chief Executive of the HPA, said: “2024 was a pivotal year for the UK heat pump market, and it's fantastic to share our figures showing a 63% increase in heat pump sales and 15% increase in individuals successfully completing heat pump training.”

Q&A MAINCOROVERBOARDUFH
With underfloor heating a popular option for many homes, John Gittens, Operations Director at Maincor, answers some questions about the company’s Overboard system.
QTo what situations is Maincor Overboard UFH best suited?
Maincor Overboard is ideal for projects such as extensions, kitchen refurbishments, or upgrading domestic heating systems. The system is quick and easy to install, offering an energy efficient solution and a comfortable internal environment that will add value to a property.
Overboard is suitable for a wide range of floor constructions, including installing on top of solid, suspended timber and floating floors. The sub-floor should comply with the requirements of the Building Regulations Approved Document L.
Using Maincor controls, manifolds, 12mm UFH Pipe and Maincor Overboard panels, it is possible to extend an existing heating system with minimal disruption to the floor and at just 22mm minimum build height.
It can be the sole source of heating, or it can be used to create a mixed heating system, offering radiators on upper floors and UFH on the ground floor, if required.
Overboard is suitable for a wide range of floor constructions
Q Does Maincor offer any design support to installers?
Maincor’s technical support ensures that help is available every step of the way; from quotation, material schedules, drawing and full design, through to visits on site and installer training. A resident renewable energy specialist will also help ensure that systems are correctly designed to give the best performance.
Q Can Overboard UFH be used on both ground and upper floors?
Yes, Maincor Overboard UFH can be used on both ground and upper floors, making it a very versatile system. On ground floors it works especially well in renovation projects
as it can be laid over existing flooring.
On upper floors, one of the benefits of the Overboard UFH system is that it’s designed to minimize the height increase of the floor. It also doesn’t need screeding so doesn’t add excessive weight or height.
Q What preparation does the floor require?
The area must be weather tight, ensuring that the panels, manifolds and electrical components are sufficiently protected from wet weather.
The floor should be solid, level, clean and free of debris. A levelling compound can be used to prepare the floor where it is uneven, while any uneven floorboards should be screwed down or replaced.

HEATING CONTROLS CHALLENGING
While smart heating controls are a great way for homeowners to create a home that is more affordable to run, there are many myths surrounding the technology that may deter potential adopters. Merlin Milner, Product Owner for Water-based Heating Systems at Drayton examines the myths and explains how controls can provide cost savings and comfort.
ASchneider Electric survey found that 43% of people said they are willing to sacrifice comfort in order to reduce their energy outgoings. However, this needn’t be the case, with today’s technology able to support homeowners in making their homes comfortable, all the while reducing costs. It is important that heating engineers help to debunk the myths surrounding smart heating controls, given that they can help support worried homeowners who are considering sacrificing their own comfort in the face of spiking bills.
1. Heating controls won’t save homeowners that much money
With 14% of British homeowners investing in a smart thermostat in a bid to reduce energy bills, there is little doubt that smart heating controls can result in worthwhile cost-savings. So, while an upfront investment is required to purchase a good quality smart heating control, such as Wiser, significant savings on energy bills can mean the technology pays for itself in a short amount of time.
Smart controls can offer significant savings when initially upgrading from a standard Class 1 room thermostat. With the average homeowner saving even more when introducing a multi-zoning system.
Making the most of the energy-saving modes available is also a must for anyone purchasing a smart heating control. Quick temporary changes to the schedule can be managed with ease using Away Mode for example, allowing homeowners to switch their heating off via the app, from anywhere, when their home is empty.
In addition, Wiser’s Eco Mode, combining optimum stop and weather compensation, learns about a home’s thermal properties. With this information, the system will switch the boiler off sooner than scheduled if required, whilst still maintaining the set point to reduce energy consumption.
Overall, research from BEAMA shows that savings of over 30% on the average heating and hot water bill can be achieved by introducing smart controls and by use of modes and multi-zoning.
Thanks to modern advancements, heating control systems offer user-friendly operation, better than ever before. However, there is still sometimes the misconception that smart heating controls aren’t suitable for all types of customer.
Systems, like Wiser, are designed to be as easy to use as possible thanks to the easy-to-navigate interface, detailed insights, voice assistant and IFTTT integration. Plus, with clear instructions, step-by-step guides and online tutorials available for homeowners to better understand heating controls, and given their cost-savings credentials, it is well worth introducing these kinds of solutions.
To make heating engineers lives easier, most smart controls are now created for simplified installation, so they can enjoy a rapid handover process before they are off to the next customer. For example, Wiser is compatible with the standard UK wallplate, which is found within 80% of homes in the UK, making it a great option for retrofitting. Plus, the system can be set up without the need to get log in details of the customer’s Wi-Fi network.
Smart heating controls have advanced in order to ensure maximum convenience for the user. Therefore, they are now able to remain operational in the event of an outage. Wiser, Drayton’s smart heating control system, for example, will remain running to the set schedule should the Wi-Fi fail.
In the event the home’s connection goes down, the heating will function according to the programme the user most recently selected. Therefore, the system will perform as programmed and won’t switch off and leave the user without heating.
Increase your knowledge
It is vital that homeowners prioritise their health and wellbeing and part of this is keeping the home warm when needed. Smart controls can help support this by offering maximum comfort and genuine cost-savings. What’s more, they are also a hassle-free, simple way to ensure ultimate convenience for homeowners.
Installers can play a key role in helping homeowners to better understand heating controls and how they can benefit their household. In order to support customers further, installers can level-up their

OPEN PROTOCOLS
Fausto Grilo, Technical Director at ESi Controls and Board Member of the OpenTherm Association, explains how open protocols in boilers and smart controls can reduce carbon emissions, improve energy efficiency, and lower energy bills.
Back in 2018, revisions to Approved Document L of the English Building Regulations, known as Boiler Plus, introduced measures to enhance boiler efficiency and user comfort. These regulations applied to boiler replacements and installations in existing homes, requiring all boilers to achieve 92% efficiency and be installed with time and temperature controls. For combination boilers, one of the following additional energy efficiency measures were mandated: flue gas heat recovery systems (FGHRS), weather compensators, load compensators, or smart controls with automation and optimisation capabilities.
Excluding FGHRS, these measures primarily aimed to reduce gas consumption by either shortening boiler operating times or lowering flow temperatures.
In 2021, the Boiler Plus Review confirmed these regulations had successfully eliminated the least efficient boilers from the market and driven the adoption of additional energy-saving measures, especially smart controls. However, the review also identified a key limitation: the lack of communication between boilers and controls, caused by non-standardised protocols, hindered the realisation of their full energy-saving potential.
Without open protocols, the interaction between boilers and thermostats is simplistic – boilers switch on when heat is requested and off when the target
temperature is reached. This on/off mechanism does not take advantage of modern efficiency technologies.
To address this, the latest government consultation has proposed that by mid-2026, all gas combination boilers and temperature controls must adopt open protocols. With this standard in place, controls can “talk” to boilers, accessing data such as flow and return temperatures and sensor readings. This communication enables boilers to modulate their output dynamically, operating at the optimal temperature to maintain efficiency.
Modulation
Another proposal in the consultation is that by mid-2028 all gas combination boilers with a capacity of ≤45 kW should be able to modulate their maximum output down to 15% without on/off cycling. Currently, some boilers can modulate to minimal outputs, offering precise control and higher efficiency. This feature is particularly useful in cases where a boiler with a larger-than-required output has been installed, ensuring it operates efficiently without overheating or short-cycling.
Open protocols ensure that boilers only fire at the required output, often just 20–30%, instead of running at full capacity unnecessarily. This reduces energy consumption and allows the system to “learn” and adjust its operation based on real-time data.
Open protocols also offer enhanced
diagnostic capabilities
Another proposed change is for all gas combination boilers to be supplied with a factory default flow temperature setting of 60°C by mid-2026. This measure prevents end-users from unnecessarily increasing boiler temperatures, maintaining their comfort while ensuring efficient operation. When boilers modulate around a set temperature instead of frequently cycling on and off, they operate more smoothly, minimising wear and tear. This not only extends the boiler’s lifespan but also reduces maintenance and energy costs. Open protocols also offer enhanced diagnostic capabilities. When implemented on both sides – boiler and control – error codes could be displayed on the control interface, much like a car’s diagnostic system.

FOCUS ON HEAT INTERFACE UNITS
As the demand for energy efficiency and low-carbon heating solutions continues to grow, Heat Interface Units (HIUs) are becoming an essential component in modern heating systems. HIUs are integral to heat networks, which offer an efficient and environmentally friendly alternative to traditional heating systems. In this article, we explore what HIUs are, how they work, their benefits, and their role in the future of sustainable heating.
What is a Heat Network?
A heat network, sometimes referred to as district heating, is a system that uses a centralised heat source – typically located in a plant, mechanical, or boiler room – to distribute hot water through a network of insulated pipes. This system is generally used to fulfil heating and hot water requirements in residential buildings such as apartment complexes, as well as educational and commercial buildings. HIUs (Heat Interface Units) are used to transfer heat from this centralised source to each individual dwelling.
What is a HIU?
A Heat Interface Unit (HIU) is a device that connects individual dwellings to a centralised heat network. Similar in appearance to a standard boiler, HIUs act as a bridge between the central heat source and hot water outlets within the apartment, such as radiators, showers, and kitchen taps.
Ed Morris, Technical Manager at Altecnic, takes a look at Heat Networks and the important role Heat Interface Units play in delivering efficient heating to homes.
Unlike traditional heating systems that require individual boilers in each home, HIUs centralise heat generation, offering energy and cost savings while providing heating and hot water on demand.
How does a HIU work?
HIUs are installed in individual properties, much like a traditional boiler would be. They are connected to a centralised boiler or heat source via insulated pipework. Inside a HIU, one or two-plate heat exchangers transfer heat from the central system to provide instantaneous heating and hot water as required.
Modern HIUs, such as those manufactured by Altecnic, feature advanced internal electronic control units that ensure efficiency, faster reaction times, and improved control.
Additional features include:
● Modulating valves to regulate hot water supply for space heating and domestic hot water.
● Thermal insulation to minimise heat loss and improve overall system efficiency.
What are the benefits of using HIUs?
There are various benefits, including:
● Minimised installation and maintenance costs:
● Maintenance and repair focus on the central plant room rather than individual boilers, reducing long-term costs.
● Installing a centralised system with HIUs is more cost-effective, quicker, and less labour-intensive compared to installing boilers in every property.
● HIU maintenance is straightforward, with all components accessible within
the unit for easy servicing by engineers.
● Compliance with low-carbon and renewable energy standards:
● Heat networks powered by central gas boilers or renewable sources like combined heat and power (CHP), biomass, solar, or heat pumps, offer flexibility and sustainability.
Are HIUs suitable for retrofitting in older buildings?
Yes, HIUs can be retrofitted into older buildings as part of a transition to a centralised heat network. This process requires careful planning to accommodate new pipework and ensure the existing infrastructure can support the communal system effectively.
● HIUs reduce energy waste as hot water is delivered on demand, eliminating losses from standing heat.
● Energy savings are maximised when the system is designed, installed, and commissioned correctly, with appropriately sized HIUs.
● Space-saving design:
● HIUs take up significantly less space than individual boilers, optimising available floor space in each property.
● Benefits for occupants:
● HIUs provide an instant supply of hot water, ensuring a high level of responsiveness.
● Lower energy bills are achieved through increased energy efficiency and reduced CO2 emissions.
● Removing the need for gas supply alleviates concerns about carbon monoxide emissions.
● Many HIUs include heat meters, giving occupants clear visibility of their energy usage and encouraging mindful energy consumption.
How do HIUs compare to traditional boilers in terms of energy efficiency? HIUs are often more energy-efficient because they centralise heat generation, which can leverage renewable energy sources and reduce overall heat loss. However, their efficiency depends on proper design, installation, and ongoing maintenance.
Can HIUs work with renewable energy sources?
Absolutely. HIUs are compatible with renewable energy sources such as solar thermal systems, biomass, or heat pumps when integrated into a heat network. This makes them an excellent choice for meeting low-carbon energy targets.
Do HIUs require regular maintenance?
Yes. Like any heating system, HIUs benefit from regular maintenance to ensure optimal performance and reliability. This includes descaling heat exchangers, checking control systems, and ensuring valves and connections are functioning properly.
HIUs act as a bridge between the central heat source and hot water outlets within the apartment, such as radiators, showers, and kitchen taps
What happens if the central plant room fails?
If the central heat source encounters an issue, all connected properties will be affected. However, most central plant rooms are designed with redundancy measures, such as backup boilers or additional heat sources, to minimise downtime.

SMART HOMES & SMART GRIDS
Peter Spurway, Head of Renewables at Viessmann Climate Solutions UK, looks at how the installer’s role may develop as evolutions in technology and energy tariffs move us towards smart homes and smart grids.
of a host of new integrated digital services.
The demands across system design, installation practices, skills, customer service and sales have been unprecedented. Even accepting the expected outcome of the Future Homes Standard consultation (the elimination of gas and oil heating in new builds within a couple of years) installers may be forgiven for looking forward to a new normal, a chance to catch their breath.
The truth is somewhat different, however. The electrification of the home, where all heat and power – both demand and varying levels of supply – is one ecosystem, is just the start.
Smart grid
In the near future (the UK is somewhat behind other countries), homes, managed by a Home Energy Management System (HEMS) such as Viessmann’s One Base platform, will be part of smart grids or virtual power plants, operated by energy companies.
Using cloud-based platforms, green energy from the wind and sun will be ‘dumped’ into heat pumps, EVs and batteries within these smart grids, as it becomes available. Domestic ‘connected assets’ will soon all play their part in grid balancing

The evolutions in technology and energy tariffs that are taking us to smart homes and smart grids are already seeing the role of installers changing –from that of a traditional plumber or heating engineer to a more consultative smart home technology installer.

brands to Viessmann), for example, harness dynamic smart tariffs by means of intelligent third-party controls such as Homely or the Passiv Smart Thermostat.
In contrast, a type-of-use tariff, such as OVO Energy’s Heat Pump Plus add-on of 15p/kWh (at the time of writing), is available to customers of Viessmann’s Vitocal 150-A and 151-A domestic air source heat pumps. This tariff is suited to customers who do not wish to rely on usage patterns by time of day, although they may continue to use their manufacturer’s onboard logic controls around the clock.
Established heat pump installers will be familiar with the evolving landscape of heat pump energy tariffs and may already be recognising the potential to add customer value in this area with advice and education.
All heat pumps are compatible with long-established time-of-use tariffs with some controllers offering smarter, automated and self-learning functionalities. Heat pumps from Carrier and Riello (sister
During the transition phase to a new pure-electric, pure heat pump world, manufacturers and energy suppliers are increasingly forging partnerships to offer attractive heat pump tariffs. But the UK market is not there yet with infinite connectivity between different heat pumps and tariffs. Installers are playing a leading role providing trusted advice to housebuilders, property developers and homeowners on the interoperability between manufacturers’ products and energy companies.
Home tech design Developers may leave the full choice of products and connected assets of the all-electric smart home to individual customer choice. But installers will play an increasingly valuable role in specifying the right foundations in terms of the HEMS platform, as well as compatible technologies, such as heat pump, Mechanical Ventilation with Heat Recovery (MVHR) system, solar PV, battery storage and EV charging.
This knowledge is a rapidly emerging requirement, particularly among housebuilders, and the HVAC industry is there to assist. Heating manufacturers such as Viessmann Climate Solutions assist by offering housebuilders and their M&E contractors, an indemnified heating layout design service, which gives due consideration at the design stage to ensure there is no clash of services in the developed design phase. Ultimately,

getting the technology package right will help determine a successful model for net zero living.
Another in-road for installers: housebuilders are increasingly looking to the services of MCS-accredited installers and designers to undertake their installation and specification requirements. Demand is picking up for an MCS sign-off that involves meeting all criteria set out within MCS 3005 including estimating running costs and performing noise calculations. Viessmann Climate Solutions UK can support the client and installer by providing an on-site MCS sign off service to new-build developers across each of its residential brands.
The future is now Through its existing, integrated, future-ready One Base software platform and commercially available APIs, all Viessmann products and digital services are interoperable with smart grids today, enabling electricity networks to automate and control these assets over the cloud, to combat peak and off peak usage patterns.
For example, Vitocharge VX3 batteries can provide a virtual power plant to support grid balancing, while Vitocal heat pumps, Vitovent MVHR and Viessmann Wallbox technologies can provide demand shifting.

Unlocking EFFICIENCY
Two important trends are helping drive business building opportunities for installers. Firstly, continued high energy prices are pushing households to prioritise energy efficiency and seek out effective control measures when it comes to heating their homes. In addition to this, consumers are becoming more environmentally aware and looking to alternative solutions, including heat pumps, to provide home heating comfort. Ian Little, Strategic Account Manager at Resideo, highlights how installers can future-proof their business with a deeper understanding of these trends and become the experts UK homeowners want and need.
Consumer demands for better energy efficiency when it comes to home heating, as well as growing interest in alternative heating system answers, are backed by evidence unearthed by Resideo. In a recent survey*, 41% of UK homeowners told us that they were likely to consider spending money on the latest heating controls such as thermostats and radiator valves if it meant they could save money over the long run for their heating costs.
In addition, the survey highlights growing awareness of alternative heating solutions – driven by recent energy price volatility. One in five homeowners said they are now ‘more likely’ to consider installing a heat pump than in previous years. This increase is reinforced by feedback from within the trade, with 55% of professional installers reporting an uptick in client interest in such solutions.
Central to capitalising on these market dynamics is the need for installers to arm themselves with the heating control information, product knowledge and training to have both informed conversations with clients and then deliver practical installation answers once agreement has been reached.
Control costs
Energy cost control, in tandem with home comfort, is a clear priority for many customers. As a result, we have seen increased demand for bespoke solutions that allow the installer to set up ‘heating zones.’
When occupants are only at home outside of working hours, many tend to heat the whole house in the mornings and evenings. But if heating is needed throughout the day, customers may wish to change this pattern so that they only warm up rooms where they work or spend time in. However, their existing heating system may not be set up to enable different areas in the house to be controlled separately.
This is where solutions such as the Honeywell Home evohome can make a huge difference. Reinforcing the very definition of smart control, evohome is a smart zoning system that uses radiator controllers to wirelessly measure and control temperatures for up to 12 individual heating zones.
With built-in Wi-Fi, this smart thermostat can be controlled at home – centrally on the evohome controller, or via the homeowner’s existing smart home voice assistant – or remotely via an app on a smartphone or tablet.
Working together
Whilst the energy and cost saving advantages of a zoning system is clear to see, solutions such as evohome can also offer compatibility benefits with emerging technologies, such as heat pumps.
According to figures from MCS (Microgeneration Certification Scheme), there are now over 250,000 fully certified heat pump installations across the UK.
The Boiler Upgrade Scheme (BUS) remains a vital part of making heat pumps more affordable and accessible to the market and recent government figures show that Boiler Upgrade Scheme applications were up 73% from January – June 2024 compared to the same period in 2023.
This reflects the growing number of consumers across England and Wales who are taking advantage of the incentive, which provides £7,500 towards the installation of a heat pump and requires it to be MCS certified. With heat pump technology working within different parameters to boilers, the minimum ‘on’ period is longer than it is for boilers as it is more efficient for the compressor. So, rather than following a morning and evening programme, it will need to be in use for more of the day. Some customers may worry this will make a heat pump control more complicated to use, however
they actually don’t have to be different to what they are used to.
Heating controls that are compatible with heat pump technology, such as the Honeywell Home evohome, as well as simple controls such as the T3 programmable thermostat and the DT4 room thermostat, are one way to satisfy consumer demands for a holistic solution that brings together proven heating control and an alternative heat source.
Train to gain
Investing time to get up-to-speed with the heating control solutions homeowners are seeking will help installers capitalise on these emerging trends.
The Resideo Academy offers a range of practical training solutions to support installers and help build product and system knowledge. This includes access to a range of hands-on training courses led by expert trainers, such as ‘Introduction to Heat Pump Systems’ in collaboration with Samsung Climate Solutions. It covers important aspects such as an overview of heat pump systems and the basics of heat pump installations and maintenance, before exploring the role of third-party controls in these types of systems.
In addition, with busy installers trying to handle time pressures, online training
course support is available so they can interact at a time most convenient to them.
Resideo Academy also provides specific courses that cover everything an installer needs to know about specifying and installing a zoning solution such as evohome. With both instructor-led and online courses available, installers are able to become product experts in a way that suits them and their business best.
What’s more, once fully trained on the merits of zoned heating systems, installers have additional help when it comes to building the right system for their client.
The online evohome System Builder, for example, has been developed to make the creation of a modular, bespoke heating control system even simpler for installers. It offers a step-by-step process to help the trade to devise a bespoke evohome zoning proposal based on specific information for an individual property.

Q&A
TF1 SIGMA MINI
Designed with the installer in mind, last year Fernox introduced the TF1 Sigma Mini filter. PHPI recently caught up with Samuel Hayes, Filter Project Engineer at Fernox, to find out a little more about the solution.
QWhy was the TF1 Sigma Mini created?
It is our belief that all properties must be able to benefit from a clean and efficient central heating system, no matter how restricted the pipework or space around the boiler might be – and so the Fernox TF1 Sigma Mini was born. By adding the TF1 Sigma Mini to our extensive range of filters, installers have a solution they can trust for whatever the type of system or scenario they are faced with on site.
QFollowing its launch in the middle of last year, what has been the reception to the new filter?
The reception to the new TF1 Sigma Mini filter has been extremely positive and we have experienced continued, high demand for it. It is based on the same tried and tested technology of the original Fernox Sigma model, so when the Mini was launched last year, installers instantly recognised that it would offer the same build quality, performance and reliability for applications with smaller and hard to reach spaces. Its success is due to the extensive research and development that goes into all our products, and we have designed the TF1 Sigma Mini with the installer firmly in mind: It comes ready to install and its slip socket manifold design means it can be fitted in under two minutes, directly below a boiler or in restricted spaces on horizontal or vertical pipework. Furthermore, its brass drain point allows for controlled and mess free servicing, without the need to disassemble the filter.
the TF1 Sigma Mini Filter can be used as a dosing point to add central heating inhibitor, which helps prevent scale build-up, corrosion, and sludge formation in the system
QFor which applications is the filter best suited?
The Fernox TF1 Sigma Mini only requires a 105mm clearance, making it ideal for social housing, new build properties and smaller volume heating systems, typically in homes with up to 12 radiators. It is suitable for both use with combi boilers and ‘traditional’ heating systems.
Despite this ultra-compact design, it does not compromise on performance and utilises a powerful neodymium magnet to enable a high efficiency capture rate, as well as a robust filtration medium that protects systems against the damaging effects of corrosion.
QCan the filter still be used as a dosing point for water treatment?
Yes, the TF1 Sigma Mini Filter can be used as a dosing point to add central heating inhibitor, which helps prevent scale build-up, corrosion, and sludge formation in the system. For example, our Fernox F1 Express is incredibly quick and convenient, dosing in just 30 seconds with no requirement to drain the system.
Q Can the dirt captured within it be discharged via a drain point?
The TF1 Sigma Mini utilises a unique drain bolt design that allows for controlled flushing and servicing of the filter, without the need for a cumbersome and expensive conventional drain valve. The low profile ¾” BSP drain connection makes it easy to connect a hose for mess free cleaning, while maintaining a low overall filter profile.
Q What warranty is available?
The TF1 Mini Filter has a 10-year warranty.

WIN A HOODIE
It has been 30 years since the launch of the Uponor Q&E (Quick & Easy) System and to mark the occasion, GF Building Flow Solutions (formerly Uponor) is giving one reader the chance to win a cosy branded hoodie and a Just Eat voucher worth £100.
win
The Uponor Q&E (Quick & Easy)
Shrink-Fit is a jointing system for PE-X pipe which can be used for the hygienic delivery of drinking water, heating systems and chilled water systems. The concept was introduced to offer installers a fast, reliable and permanent pipe jointing solution that removes the need for hot works, adhesives, fluxes or sealants.
The company says that this can be achieved thanks to the elastic characteristics and thermal memory of the Uponor PE-Xa pipes: when an Uponor PE-Xa pipe is expanded with a compatible tool, its structure means it strives to return within a short time back into its original form. As such, when using the Q&E Shrink-Fit fitting, the pipe serves as the seal material by resuming its original shape to produce a bond, which according to the company, is stronger than the pipe itself.
For your chance to win a branded hoodie and a £100 Just Eat voucher pleasewww.rdr.link /pbl017
Installation
Cut: Cut the PEX pipe to the size required using standard pipe cutters. Expand: Place the Q&E ring around the pipe (the stop edge allows for accurate positioning) and use the Milwaukee expansion tool to expand the pipe.
Connect: Add the Q&E fitting and wait 30 seconds for the pipework to shrink back around the fitting to form an airtight seal.
(Always follow manufacturers full instructions)
Fit and forget
There are no O-rings or any other moving parts that could potentially fail, which the company says minimises the potential for leak liability, system repair and maintenance costs.
According to the company the design has a connection system that provides installers with the confidence that the system is 100% secure. This, it says, is thanks to the product’s fittings which have a visible stop point to ensure they are pushed on far enough. Even on smaller sized connections, the system can withstand combined pulling forces of up to 1,300kg, according to the manufacturer.
Flexibility
The company says that Q&E can also be used to connect copper, steel and other plastic based systems including other Uponor pipe systems such as the MLCP or Riser. It is available in a range of high-performance plastic polyphenylsulfone (PPSU) and threaded brass fittings for pipe dimensions ranging from 12-63 mm sizes to suit each application.

THE DECARBONISATION OPPORTUNITY
Tindustry, emphasising the need for residential and commercial installers to upskill and adapt. By investing in training and education, installers can position themselves as experts in this expanding field, contributing to the broader goals of sustainability and energy efficiency. As the demand for heat pump installations continues to grow, the role of skilled installers becomes increasingly pivotal, ensuring a seamless and effective transition to a greener future.
One of the primary benefits of heat pumps is their energy efficiency. Heat pumps can generate 3 to 4 kilowatts (kw) of heat for every 1 kw of electricity used and under optimum conditions can achieve as much as 400% efficiency. This compares favourably to gas boilers.
consumption. Skilled installers can maximize heat pump performance through proper installation that not only enhances energy efficiency but also translates into worthwhile cost savings for end-users. They will also be able to guide customers on system selection, placement, and maintenance, ensuring that they get the most out of their investment.
Regulations and standards
What’s more, as the HVAC industry is subject to evolving regulations and standards aimed at promoting energy efficiency and reducing greenhouse gas emissions, skilled installers play a pivotal role in ensuring that heat pump installations comply with these requirements. By staying updated on the
for competent installers, Hamid Salimi, Product Manager from Daikin, explores the importance of upskilling and the opportunities this can bring.
latest regulations, installers can navigate the landscape of standards and certifications that are required, contributing to the industry's commitment to sustainability. Companies like Daikin can play a pivotal role in this effort by keeping their installers up to date with any changes in regulation as well as offering continuous support and training.
Similarly, as heat pump technology continues to evolve, installers must keep pace with the latest innovations. From smart controls and monitoring systems to advancements in refrigerants, staying up to date is essential for providing top-notch installation services. Upskilling not only enables installers to embrace these technological advancements but positions them as industry leaders capable of delivering cutting-edge solutions to their customers.
Making the move
There are plenty of similarities between installing a heat pump and the installation of traditional heating and cooling systems that makes upskilling straightforward. The main difference between heat pumps and traditional systems lies in the specification of the products. Heat pumps require correct sizing, proper placement, and careful understanding of the homeowner or commercial client’s requirements.
Given these differences, some installers may be uncertain about how to expand
their services into this new area. There may also be some concern around ensuring the business delivers a high standard of service to customers. That is why it is important to partner with a manufacturer who can offer support at every stage.
Training is one of the most important first steps and heat pump manufacturers are often the best place to start in looking for suitable courses. For example, Daikin offers installers free product training sessions that are focussed on the key heat pump technologies and cover the installation, commissioning and maintenance. We have a nationwide network of dedicated training centres as well as our network of Sustainable Home Centres to ensure installers can access the training at a convenient location to make it as easy as possible.
it is important to partner with a manufacturer who can offer support at every stage
Training courses are available for a wide range of trades, from electricians that would handle the wiring and connection side only, to courses on fault finding, diagnostic and repairs for F-Gas certified engineers or fault finding, diagnostic and maintenance for those that do not have their F-Gas certification.
It’s worth pointing out that in order to take full advantage of the current industry opportunities, installers may need to invest in further training and assessments to
achieve Microgeneration Certification Scheme (MCS) accreditation. Installers must hold this certification for new residential heat pump installations to be eligible for Government grants. In England and Wales this is worth up to £7,500 or more in Scotland. Daikin has Government approval to provide the training required for the MCS scheme.
Beyond training, it is also important to have support during installations, including assistance with technical enquiries. This is particularly true with the first heat pump systems your business completes. Many, manufacturers, including Daikin, offer free commissioning support on initial installations.

CONVERTING TO ‘PRESS-FIT’
Today, specifiers want products that will help reduce the carbon footprint of any new building or refurb projects, and this is increasingly impacting on the choice of building materials; and end-users are increasingly asking for materials to be used that are environmentally friendly. Whilst brazing has its place, increasingly building managers and owners are prohibiting the practice within their properties. In 2018 the government banned the use of combustible materials in and on the external walls of new blocks of flats, hospitals, residential care premises and student accommodation over 18 metres in height.
Following a review and consultation, the government has put forward regulations to extend the ban to also apply to hotels, hostels and boarding houses. This has led to increasing numbers of experienced contractors within the HVAC sector looking to be trained in the use-of press fit.
Training scheme
In the past 12 months, Conex Bänninger has trained more than 100 contractors –either through face-to-face tuition at our training academy HQ in Birmingham,
on-site or undertaken online through Teams.
Our scheme is for installers using >B< Press copper fittings (12 to 54mm), which are suitable for hot and cold-water applications, including drinking water.
To qualify as a Certified Installer, an installer must have completed the >B< Press training, either on-site or at our academy. Each successful candidate is awarded a personalised Installer Card showing the date of completed training and an expiry date, along with a photo of the card carrier. The Installer card is valid for five years, after which the tradesperson must attend for a training top-up.
Whilst some may view press-fit as deskilling the industry, it’s really a transition towards safer working practices. Just as importantly, installers are recognising the significant time savings that can be made on a job. Admittedly, some view the initial outlay for the press tool as prohibitive to entry, but the return on investment can often be achieved in a month or two.
Over the past decade there have been many developments in the heating and plumbing industry including health and safety regulations driving new practices and the need for companies to reduce their carbon footprint. One outcome has been a new generation of plumbing and heating engineers being trained in the use of press-fit fittings for joining pipes and, whilst apprentices are taught brazing at college, many become press-fit converts from the outset says Lisa Cox, Conex Bänninger’s UK National Sales Manager.

REMEHA BY BAXI QUINTA ACE COMMERCIALBOILER SERIES
Baxi has announced the arrival of the new Remeha by Baxi Quinta Ace high performance boiler series, now available with aluminium and stainless-steel heat exchanger options.
The company is billing the series as the ‘energy transition boiler’ and the new Quinta Ace will include an all-new optional gas adaptive kit for biogas, designed to support the transition towards a net zero heating system.
It says sustainability has been included in the new-look design to achieve a reduced life cycle assessment (LCA) using a lower carbon ABS plastic boiler cover and recycled packaging and updated manuals.
James Matthews, Director of Building Solutions at Baxi, said: “As building owners and managers look to reduce the carbon intensity of the heating system, hybrid systems are seen as an achievable step on the decarbonisation roadmap by many. Capable of operating at 40˚C temperature differential, the Quinta Ace is a versatile choice in hybrid solutions, working alongside renewable technologies like our Auriga air source heat pump range to meet peak heat demand. Now, with its new gas adaptive feature, the new and improved Quinta Ace offers the future option to switch to low carbon biogas to achieve full heat decarbonisation.

“Using LCA in the product re-design has also resulted in a reduced environmental impact,” James continued. “This helps building services professionals and building managers to optimise carbon reduction and meet sustainability goals.”
Multiple outputs
The new Quinta Ace is available in 15 outputs from 30 to 160 kW (up to 1,200 kW in cascade), with a choice of aluminium or stainless-steel heat exchanger. The new range uses the same Ace control platform, the same performance level controls, and the same standardised cascade sets and flue systems. Fully backwards compatible for ease of replacement, the new Quinta Ace is supported by a 7-year warranty when commissioned by Baxi (a standard 5-year warranty otherwise) and year-round 24/7 customer support.
“The new Quinta Ace range is the Quinta-ssential commercial choice for the future of sustainable heating,” said James. “We’ve taken our best-selling product, extended the range, added new sustainable features, and given it a whole new-look aesthetic. Our new hybrid-ready, ‘energy-transition’ Quinta Ace is part of our commitment to offer customers increased options and solutions, backed by Baxi’s expert sales support and technical design services, for a seamless move to net zero heating.”
