Familiar solutions
It was recently revealed that during March this year there were 5,604 certified Heat Pump installations. When compared with March 2024, this was a 22% increase. The figures, taken from the MCS Data Dashboard, demonstrate the steady rise of heat pump installations in the UK.
Other low carbon alternatives, such as Solar PV and battery storage, also saw rises in the month, with a total of 31,000 certified installations across the period. Ian Rippin, CEO at MCS, commented, “It’s great to see that the number of people adopting low-carbon alternatives is continuing to grow month on month.” You can read more about this story on page 8.
Manufacturers are launching new Heat Pumps, notably those utilizing the R290 refrigerant, and an increasing number of training courses are available. Helped by the BUS (Boiler Upgrade Scheme) grant, and with energy providers exploring new tariffs to support users of the technology, it would seem that 2025 could be another year of growth in heat pump installations.
However, to be fully reassured heating engineers more familiar with traditional solutions will want to get ‘hands-on’ with Heat Pumps and speak directly to the people manufacturing them. One chance to do this occurs in late June when the InstallerSHOW returns to the NEC. With a number of Heat Pump manufacturers present at the event, alongside a wide range of other companies from across the sector, engineers can take the opportunity to explore new solutions in the market and speak directly with their creators. You’ll find a preview of the event on page 31.
At the moment it is Air Source Heat Pumps (ASHP) that are gaining widespread attention, but they are not the only option. Another is an Exhaust Air Heat Pump (EAHP), which works by extracting warm air from inside a building, capturing its thermal energy through a refrigeration cycle, and using it to heat water and indoor spaces. In this issue we speak with NIBE about the technology and its S735C unit. You can read more on page 16.
With plumbers and heating engineers often relying on solutions that are familiar and trusted, it is clear to see why new technologies can take time to break into the market. However, if they provide solutions and offer new advantages it is likely they will gradually become more widely adopted... perhaps even becoming the next generation of familiar and trusted solutions.

RETROFITTING UFH WITH LOW CARBON TECHNOLOGIES
With sustainability and energy efficiency continuing to be high on the agenda for residential and commercial properties, renewable technologies such as heat pumps and solar are becoming increasingly popular. Here Diana Puiu, Technical Design & Support Manager from GF Building Flow Solutions (formerly Uponor), outlines some things to consider when retrofitting underfloor eating with these low carbon technologies.
Building regulations are clear when it comes to replacing wet heating systems. Part L in England and Wales requires a maximum flow temperature of 55°C, while Scotland’s compliance guidance stipulates 50°C. These lower temperature requirements make low carbon technologies like heat pumps and solar thermal systems the logical choice to replace traditional boilers.
Underfloor heating (UFH) systems are a companion for renewable technology due to their large surface area, which results in lower flow temperatures, typically 35-40°C. So, when installers retrofit UFH with low carbon heat sources, they comply with regulations and deliver significant benefits to the property owner, including improved thermal comfort, maximised energy efficiency, and reduced running costs.
Installing UFH is not complicated if you have addressed several essential factors to ensure correct specification. But before you can plan the installation, you must first decide what system is best for your project.

Which system?
Electric UFH systems consist of cables or mats installed under the floor. They can be cheaper and easier to install, but their running costs can be higher, so this type of UFH is better suited to smaller-scale installations such as residential bathrooms or kitchens. If you are installing electric underfloor heating in more than one area, you must ensure that the property’s electrical system can cope with the additional electricity demand, or the UFH could overload it.
Hydronic (water) UFH systems, which use a network of pipes to circulate hot water through the circuit to provide radiant heat, benefit from greater energy efficiency and reduced heating bills. These systems work well for bigger areas and with
low-carbon heating like solar thermal and heat pumps.
Floor structure
The floor’s structure can often determine the choice of system. If raising the floor is not possible, low profile UFH systems, such as the Uponor Minitec, can be installed on top of the existing floor covering or screed or as part of a complete floor replacement. If the floor structure has a low static weight-bearing capacity, systems like the recently launched Siccus 16 dry UFH system are ideal. Siccus is designed for residential retrofits, requires no screed and has a low profile, minimising disruption and avoiding the need for significant floor build-up. This makes it suited to timber floors or upstairs retrofits with weight and height limitations.
Good insulation and thermal mass are key to getting the best performance when fitting underfloor heating with renewables like heat pumps and solar



Thermal performance
Good insulation and thermal mass are key to getting the best performance when fitting underfloor heating with renewables like heat pumps and solar. Without adequate insulation, a significant amount of heat can be lost to the subfloor, reducing the advantages of low-temperature heating.
You might need to upgrade the existing insulation in older properties to prevent unnecessary heat loss. The floor’s thermal mass, usually the screed, also plays a big part in how efficient the system is. Getting the insulation right alongside enough thermal mass means better heat retention and a more even heat distribution.
This becomes even more important for commercial buildings, so insulating beneath the UFH pipework will prevent heat from escaping into the floor and direct it upwards instead.
A solid connection
One key area where heat can be lost but often gets missed is where the heat source connects to the UFH system. Using pre-insulated pipe solutions, like Ecoflex Thermo Twin HP, which is designed for heat pumps, can ensure minimal heat loss between the heat source and the heating system. This helps optimise energy efficiency across the whole heating loop.
Flooring material
Another consideration is the type of flooring that will be used above the underfloor heating system. While many floor coverings can work with UFH, installers should pay close attention to thermal conductivity. In residential properties, carpets and

Installing UFH is not complicated if you have addressed several essential factors to ensure correct specification
underlay are recommended to have a combined insulating value of no more than 1.5 Tog. Correct insulation is even more critical in commercial environments, where the carpet is specified for sound absorption. As a rule of thumb, values should be no more than 1.5 Tog, especially for heat pump systems.
Materials like vinyl, stone, engineered wood, tile, and polished screed offer excellent thermal conductivity and are ideal for use with underfloor heating systems. However, always check the manufacturer’s recommendations to ensure the flooring is suitable for the system you are installing.
An expanding market
As awareness of the benefits of combining
low carbon energy technology with UFH grows, demand will increase further. This is the ideal time for installers to offer low carbon heating solutions and take advantage of this growing market. However, correct product selection and system design are key. Engaging early with manufacturers like GF Building Flow Solutions will ensure access to technical guidance, design support, and product solutions tailored for retrofit.

Martyn Bridges, Director of Governmental and External Affairs at Worcester Bosch, looks at four ways to maximise boiler efficiency.

MAXIMISE BOILER EFFICIENCY


The government’s consultation on raising product standards for space heating concluded in March. We’re now waiting to see how our responses to its 96 questions will be actioned.
Some of the proposals involve removing certain boiler controls from the market. It principally highlights on-off controls, the ‘old-fashioned’ thermostats that literally switch off the boiler once the room reaches the desired temperature.
Controls are an important component and for some years, Load or Weather compensation controls modulate the output of boilers to their absolute minimum whilst still achieving the desired room temperatures. Let’s take a look at what the proposals could mean for consumers and the strategies that could make their heating more efficient.
New combi boilers have energy-saving controls
The Boiler Plus standards that were introduced in 2018 require installers of gas-fired combi boilers to implement modulating controls for additional energy efficiency. These are known as load compensation or weather compensation controls, and they’ve been a requirement for every combi boiler installed in the UK for the past seven years.
Rather than turn the boiler on or off, these controls use two-way communication to inform the boiler of how much heat is
required. The controller can then regulate its temperature downwards to operate at the minimum output needed to provide a comfortable level of heat in the house.
The importance of controls
Controls improve the energy efficiency of a boiler by lowering the temperature it runs at and increasing how much it condenses. And critically, it’s not just boilers installed after 2018 that are compatible.
The majority of combi-boilers that predate the Boiler Plus Standards also have the ability to modulate and communicate with controls. It’s very rare that a boiler produced in the past 15 years can’t be controlled in this way. In fact, the

if the homeowner isn’t interested in changing controls, they can use other techniques to improve heating efficiency
Worcester range of Comfort controls have been doing this since 2014.
Replacing on-off thermostats with load or weather compensation controls is a surefire way to increase efficiency. But even if the capacity is there, the homeowner must be open to the upgrade.
Controls can be challenging to install In most cases, new controls need to be electronically wired to the boiler by a professional. The potential for disruption stops many homeowners from even considering installation.
It’s also often the case that homeowners only think about upgrading their heating system once it stops working. But if the homeowner isn’t interested in changing controls, they can use other techniques to improve heating efficiency.
Manually lowering the temperature
Combi boilers with separate controls for hot water and heating can be adjusted manually – and it’s a simple enough adjustment to be made by the homeowner. Modulating the thermostat down to 50 to 60 degrees centigrade is usually sufficient to provide enough warmth to heat the home while lowering the overall output.
Essentially, this emulates the action of a load compensation boiler by lowering the flow temperature to optimise its condensing. It just requires manual adjustment.
Balancing the heating system
Another method is to make sure the heating system is correctly balanced, though this technique requires the expertise of an installer. It’s an essential fix for heat pumps, but also important for boilers.

With a condensing boiler, homeowners should endeavour to reach a 20-degrees centigrade differential between the incoming flow to a radiator and the outgoing return.

This is usually achieved by regulating the radiator’s lockshield valve and measuring the incoming and outgoing temperatures on the two pipes, then adjusting to achieve the 20-degrees difference.
It’s a more straightforward fix if the thermostatic radiator valves are auto-balancing, which uses a new technology and makes it easier to set up.
Checking for water quality
A water quality check is another worthy consideration. This is a professional check to assess the efficacy of any inhibitor installed within the system, and whether the water is contaminated with impurities. Contaminants such as oxygen ingress or discoloured water could hamper the transfer of heat into the water.
In that case, it’s certainly worth flushing a system with a power flush regime or even just a gravity flush. Clean water can pay dividends for boiler efficiency.
Checking the timings
With many heating systems, we find the timings of the heating on and off periods are not tuned to the householder’s living patterns. The factory settings are generally just an estimate of the typical living patterns of a household; however, with combined energy bills nowadays averaging £1,850 a year for a typical house, any reduction in boiler operating times is worth doing. Just changing the boiler start and end times everyday by 30 minutes will give noticeable savings, yet probably no noticeable change in comfort.
We find that smart controllers are interacted with a lot more, as you can change the timing patterns from the comfort of your sofa on your phone rather than having to stand next to a wall-mounted programmer with the instructions in your hand in some dimly lit airing cupboard.
The future of domestic heating controls
Greater efficiency doesn’t always require expenditure on new controls – it can be achieved through actions as simple as boiler temperature and water quality adjustments. As for the effect on homeowners, time will tell whether the government will mandate domestic controls for all.

EXHAUST AIR HEAT PUMPS Q&A
PHPI speaks with Rick Clarke, NIBE UK’s Product Manager, to discover more about Exhaust Air Heat Pumps, some of the features of the company’s S735C unit and to find out the controls available with it.
QWhat is an Exhaust Air Heat Pump and how does it differ from Air Source Heat Pumps?
An Exhaust Air Heat Pump (EAHP) is a versatile, all-in-one system that provides heating, domestic hot water (DHW), cooling, and mechanical ventilation from a single, internally installed unit. It works by extracting warm air from inside a building, capturing its thermal energy through a refrigeration cycle, and using it to heat water and indoor spaces before expelling the cooler air outside.
By contrast, an Air Source Heat Pump (ASHP) relies on external air as its heat source and requires an outdoor unit to operate. While both technologies use the same basic principles of heat exchange, ASHPs do not provide ventilation and usually require a separate DHW cylinder. Additionally, ASHP efficiency can fluctuate with outdoor temperatures, whereas EAHPs benefit from a more stable indoor air environment, making them especially efficient in modern, well-insulated homes.

QTo what types of property is an Exhaust Air Heat Pump best suited?
EAHPs are particularly well-suited to smaller, modern properties that are built with energy efficiency in mind. The most common use cases in the UK include:
● New-build flats and apartments (1-3 bedrooms): These properties often have controlled ventilation requirements and benefit from a compact heating solution that integrates multiple functions into a single unit.
● Small to medium-sized houses: While EAHPs are more common in flats, they can also be used in houses if proper space is allocated for the necessary ducting.
● Retrofit projects: Although EAHPs are most commonly installed in new developments, they can also be retrofitted into existing properties, provided that space is available for ductwork.
The key requirement is that the building has a relatively low heat loss (typically under 6-7kW), and sufficient airtightness to ensure the EAHP operates efficiently.
QWhat are they key features of the S735C Exhaust Air Heat Pump from NIBE?
The NIBE S735C is a compact, high-performance EAHP that combines multiple functionalities into a single unit with a small 0.6m² footprint. Its standout features include:
● Heating up to 6.5kW, ensuring a warm and comfortable home environment.
● A built-in 180-litre domestic hot water cylinder, capable of meeting the daily hot water needs of a typical household.
● Cooling function up to 3kW, providing comfort during warmer months.
● Mechanical ventilation, which ensures a continuous supply of fresh air while recovering heat from outgoing air to improve energy efficiency.
● Smart connectivity via the myUplink app, enabling homeowners to monitor and adjust system settings remotely.
This combination of heating, hot water, cooling, and ventilation makes the S735C a highly efficient and space-saving solution for modern homes.
QWhat controls are available?

The NIBE S-Series smart controls come factory-installed, providing a user-friendly and highly intuitive system. Key features include:
● Wi-Fi connectivity, allowing remote access through the myUplink app.
● A touchscreen interface, making it easy to adjust settings and monitor system performance.
● Smart Room Control (SRC), which utilises AI for better comfort and efficiency.
● Smart Price Adaption (SPA), enabling the system to adjust operation based on electricity pricing, helping homeowners reduce energy costs (offline only). These advanced controls enhance user experience while maximising the efficiency of the heat pump.

RProduct Manager for Schlüter-Systems, Andrew Saxon, offers advice on best practice when planning and installing electric underfloor heating systems.
ight back to Roman times, few things in the built environment can have delivered such a sense of comfort –and even luxury – as underfloor heating; yet the technology remains potentially problematic, with the quality of installation being pivotal to both the performance and the likely overall lifespan of the system.
In many properties, the space heating is still primarily delivered via conventional radiators, but in refurbishment as well as new-build situations, electric underfloor heating systems are widely regarded as offering a convenient solution for upgrading the comfort in bathrooms, particularly in the context of under tile installations.
Instead of a cold and unwelcoming surface beneath bare feet, a correctly specified electric system can deliver controllable warmth, not just from below, but also creating a regulated temperature within the room-space itself. The more advanced and adaptable systems can further be incorporated behind tiled walls.
Planning
Planning the installation is crucial, especially in larger bathrooms or sports changing rooms as even considering modern standards of insulation, the north side is often measurably colder than the south; with zoning being the obvious answer. As with the pipe runs to hydronic systems, the designer and contractor must create separate cable circuits, linking back to individual thermostats. Significantly, the two zones may well be of different sizes, and not necessarily feature the same number of cables.
From a purely practical perspective, it is difficult to connect more than two heating cables into each thermostat, which is why Schlüter®-Systems’ DITRA-HEAT offers customers a selection of 17 different cable lengths for the 240 Volt circuits – rising from 4.6 up to 244 linear metres to address areas from 1.1m2 to 22.7m2. They will offer
ELECTRIC UFH

an output of 136W/m2, with an actual limit on capacity of 3,600 Watts that can run from one thermostat.
Connections
It is relevant here to highlight an issue common to many electrical underfloor heating systems, where the transition between the hot cable which delivers warmth to the floor build-up, and the cold stretch which connects to the thermostat, rely on a soldered connection. Unfortunately, such connections are inherently brittle and subject to failing; even months or years after the installation is complete.
The DITRA-HEAT cables feature a seamless transition between cold and hot legs. The cold leg is four metres long and employs a very thin strand wound around it, which reduces the electrical resistance to minimise the heat output generated; and this negates any problems of overheating where the connection is made to the thermostat. Additionally, DITRA-HEAT cable contains multiple very fine, but strong strands which extend along the full length.
And as an integrated system solution, DITRA-HEAT’s 4mm diameter cables are laid within a studded, fleece backed membrane, which serves as both an
insulating carrier and a decoupling layer to help distribute stresses within the build-up. For floors, the cables are laid within every third row of studs, and every two behind wall tiling.
The company always recommends that the installer runs two temperature sensors from the chosen position within the floor circuit, back to the wall, as there is always a possibility of one failing during the lifetime of the installation. In such a situation, it is then a simple matter to disconnect the first sensor from the thermostat and wire in the ‘spare’.
Testing
Schlüter®-Systems also recommends three stages of testing before you tile: as each zone is laid, then during spreading of tile adhesive to guard against damage caused by pushing the cable home with a trowel, and after the tiles are installed.

Schlüter®-Systems continues to develop the DITRA-HEAT system, with the latest sophistication being the ability to control the heating output via a home’s Alexa, as well as using the manufacturer’s App, or via conventional controls.

DRAYTON MOTORISED VALVES: THE EASY, RELIABLE CHOICE FOR INSTALLERS
When looking to manage the flow into different circuits each with their own individual heating and hot water control, motorised valves are an installer’s go-to. At Drayton, a comprehensive range of motorised valves are available, all designed to make installation, maintenance and replacement easier than ever.
When looking to manage the flow into different circuits each with their own individual heating and hot water control, motorised valves are an installer’s go-to. At Drayton, a comprehensive range of motorised valves are available, all designed to make installation, maintenance and replacement easier than ever.
Simple to install
One of the most popular features of the Drayton motorised valves amongst installers is the ‘snap-on’ actuator. This makes installation much simpler for heating engineers, as the head can be detached and moved out of the way when working.
Easy for repairs and replacements
Carrying out maintenance or repairs to the system is also made easier with the Drayton motorised valve. The ‘snap-on’ actuator also makes replacing it less hassle, as installers don’t need to drain down the entire system if only a replacement actuator is required. When working, the actuators provide 100% tight shut-off thanks to the internal synchronous motor and the spring return. The manual lever and position indicator on the Drayton motorised valve can also assist with fault finding, as installers can immediately identify what position the valve is in. Plus, to maximise service life of

the valve, the synchronous motor is easily replaceable.
As well as being designed with industry-standard wiring, the dimensions of Drayton motorised valve body makes it ideal as a replacement for any existing valve that needs switching out.
Reliability you can trust
Drayton motorised valves are manufactured here in the UK and are designed for UK homes.
Designed to offer reliability, durability and longevity, the high-quality motorised valves come with an 18-month warranty for further peace of mind, or an extended 5-year warranty for installers registering products through Drayton Rewards+.
Choosing the right motorised valve for the job
The Drayton motorised valves come in two body configurations – 2 port and 3 port –and the type of valve fitted required will depend on the type of system plan an installer is looking to build. A 3-port body with mid-position actuator creates a Bi Flo Y plan and should be fitted after the pump. Meanwhile, on a Twin Zone or Multi Zone S plan system, multiple 2-port valves will be needed, as each circuit will require its own motorised valve. When looking to

create a system with a zone of wet underfloor heating, a Multi Zone plan would allow for this.
All models in Drayton’s range of motorised valves are available in two sizes for 22 millimetre and 28 millimetre copper, with compression fittings. The valve bodies and actuators can be purchased in packs of head and body or separately to make replacing as cost-effective and easy as possible.
Get more from Drayton
Should support ever be required when fitting Drayton’s range of motorised valves, the manufacturer’s Plymouth-based customer support team is on hand to help. Additionally, installers can access free training on Drayton’s range of valves via Drayton Rewards+. As well as levelling up their knowledge, which will earn them points upon completion of the training courses, installers can register their product installations for points, which can be redeemed against a range of items on the Drayton shop. For a limited time, double points are available on all motorised valve registrations.

HARMONISING HEAT
Myson UK provides a guide to combining underfloor heating and radiators.
When it comes to installing or updating a heating system, people often feel they have to choose between underfloor heating and radiators. Buildings are all individual and can be very different in terms of heating needs and energy consumption, so there is no ‘one size fits all’.
Both underfloor heating and radiators have their pros and cons. Underfloor heating frees up valuable wall space, offers comfortable warmth, and can be split into zones which enables setting the preferred temperature per room or zone. Radiators, on the other hand, react fast to temperature changes in the room due to their lower water content and lower thermal mass.
Why combine UFH and radiators?
“As one of few manufacturers to offer both underfloor heating and radiators, we believe a combined heating system is a more complete solution that offers many advantages”, says Nabeel Javaid, Market & Applications Product Specialist at Myson UK. “Some situations might be best suited to one or the other but, thanks to technological developments and product innovation, underfloor heating and radiators can both be installed in various areas of a building. This way you create an optimal heating system that’s flexible and energy efficient.”
Some advantages of combining UFH and radiators
● Zoned heating control Underfloor heating can be split into separate zones thanks to separate heating circuits and installation distances, while radiators can be installed freely in single rooms, depending on the zone. End users can then adjust temperatures in individual rooms based on their specific needs and habits, enhancing energy efficiency and reducing the amount of wasted energy.

● Comfort The complementary nature of underfloor heating with radiators boosts the overall comfort. “The bathroom is a perfect example of a room which benefits from the combination of underfloor heating and radiators”, says Nabeel. “Underfloor heating creates a consistently warm floor that’s very comfortable to walk on barefoot. It also helps to dry wet floors faster. A radiator is a great addition to help boost the temperature, when needed, for optimal comfort in the bathroom.”
● Energy efficiency A combined system offers great energy efficiency, especially when you combine underfloor heating with low-temperature radiators and a heat pump or condensing boiler.
● Flexibility in design This hybrid approach offers greater flexibility in design, particularly for renovations. Radiators are a great solution for spaces where retrofitting underfloor heating may be challenging, while underfloor heating can seamlessly integrate into open-plan areas or bathrooms. This allows the heating system to be fully tailored to the building layout and the end users’ lifestyle.
Technical considerations
According to Nabeel, the key to an optimal result lies in the considered combination of the different parts of the system. “As experts
in heating solutions, we are able to help our customers optimise that combination in four important facets of any heating system: the system design and planning, the pipe network and heating circuit temperature differentiation, correct balancing of the emitters, and the control systems.”
Careful system design and planning is a must to ensure a hybrid system works optimally and the various components won’t counteract each other. Zoning, for example, with separate thermostats and control systems is important to allow each area to operate independently. “Our internal experts are happy to assist in the planning stage to create the best possible heating system, taking into account the different features and purpose of the building.”
“Last but certainly not least, there are the controls. These play a pivotal role in maximising comfort and efficiency. Zoning technology and smart controls, such as the ones in our Unisenza and Unisenza Plus range, allow for precise temperature management of both type of emitters. What’s more, with the Unisenza Plus app you can easily combine and control every part of the heating system from a single platform, wherever and whenever you want. This helps to reduce energy consumption and maintain optimal comfort at all times.”

HOLISTIC LOOK
Installing Hansgrohe’s Xelu vanity unit & Tecturis basin tap
For installers looking to offer customers a holistic bathroom aesthetic, hansgrohe’s expansion into ceramics and vanity units could be a welcome addition. Installers can now elevate the coordination of their recommendations in the bathroom by incorporating showers, taps, accessories, ceramics and furniture all from the one brand.
As an example of how this cohesive look can work in practice, the Xelu Q vanity unit and basin paired with the Tecturis E two-hole basin mixer tap is a combination which the company believes can create a standout style. It says, the vanity unit offers a premium finish with innovative storage, while the basin mixer tap not only looks great but also features EcoSmart+ technology, designed to reduce water flow without compromising the way in which water is delivered to the end user
Tap control
Additionally, hansgrohe has introduced a new way for consumers to turn on their tap with a control which can be fitted to the front of the compatible, pre-punched hansgrohe basin.
This feature, it says, may be a particularly welcome innovation for disabled customers, notably wheelchair users, who may find it difficult to reach across a basin and adjust the tap temperature, particularly on a single lever basin mixer tap.
The control button uses Select technology – a press turns on the water, whilst twisting the button changes the water temperature to the desired level.
Here, the company takes a look at how to install these two products. For this installation, the 780mm Xelu vanity unit has been used with the 800mm Xelu basin.

From extensions to garden offices, macerators and automatic lifting stations make it possible to handle wastewater where gravity drainage won’t reach. Adam Ferneyhough, Country Director UK for DAB Pumps, highlights why fast-fit features and easy maintenance are key to choosing the right system for the job.
When traditional gravity drainage isn’t possible, automatic lifting stations offer a reliable solution for moving wastewater to where it needs to go. They are popular in extensions or loft conversions where routing conventional pipework is impractical and are particularly useful for retrofits, property upgrades and extensions, giving developers and installers the flexibility to deliver functional, compliant spaces in tight or unconventional layouts.
Whether it’s a basement bathroom, a toilet in a garden office or a utility area on the wrong side of the soil stack, these compact units make it possible to add sanitaryware in previously off-limit locations – without the upheaval of major pipework rerouting.
While automatic lifting stations solve a practical problem, not all designs are created equal. When choosing a unit for a new installation or retrofit, installers should of course look for compact dimensions that suit tight or awkward spaces, along with quiet, reliable performance and features like anti-odour protection for added user comfort. But the best systems should be intuitive to install, quick to set up and easy to maintain.
The installation process starts at the point an automatic lifting station is selected. The Genix range has three models that meet a wide variety of needs. The Genix and Genix WL are suitable for toilets, showers, washbasins or bidets, while the Genix VT has been designed specifically for grey water use, such as with sinks, washing machines or dishwashers. All three offer quiet, dependable performance for situations where gravity drainage isn’t available.
NEED A LIFT?

Units arrive with everything in the box: hose clamps, pipe adaptors, fixings and a quick-start guide
Maintenance
Let’s be honest – no one wants to deal with a macerator that’s blocked. But even with the best will in the world, it happens. Wipes, sanitary products, even kids’ toys –they all find their way in. What matters is how the system lets you deal with it.
With the Genix range each unit features a removable motor block that can be accessed in-situ, with no need to disconnect the discharge pipework. You release the block, lift it out, clear the fault or rinse it through and put it back in. No pipe cutting or pulling the unit off the wall and no fighting with awkward angles under a basin.
This approach also makes it easier to access other key internals. Whether it’s the capacitor, PCB, pressure switch or the grinding blades, every major component is
accessible without full disassembly. That’s less time on the job and less chance of something going wrong in the process.
Time-saving
Additionally, because you don’t need to cut into pipework or shift the unit, there’s no need to isolate and drain down the system unless it’s absolutely necessary. That saves a significant chunk of time and avoids turning a 30-minute call-out into a two-hour clean-up. Even little things make a difference: integrated non-return valves reduce backflow when you open the unit. Quick couplings help minimise mess.
Units arrive with everything in the box: hose clamps, pipe adaptors, fixings and a quick-start guide. But it’s the thought that’s gone into future servicing that really pays off. If customers call because something’s gone wrong, you want to be in, out and on to the next job.
From compact sizing and full accessory kits to maintenance you can carry out without disruption, Genix is designed to be as stress-free as possible.

AC-90 BIO Q&A
Following the recent launch of its AC-90 Bio multifunctional oil, we spoke with Michelle Ionn, Marketing Manager EMEA, CRC Industries, to discover the reasons behind the development of the new solution and its variety of uses.
QFor what kind of applications would plumbers and heating engineers use a lubricating spray or multifunctional oil?
AC-90 Bio is a versatile solution designed to tackle various maintenance challenges. It effectively loosens stuck or rusty bolts on pipe connections, taps, and seized stopcocks. Additionally, AC-90 Bio enhances the performance and longevity of cutting equipment by protecting blades during pipe cutting. Its anti-corrosion properties safeguard metal surfaces exposed to moisture and condensation. Particularly beneficial for connecting rubber flanges to plastic pipes, AC-90 Bio significantly reduces time and effort in these tasks.



QWhy has the company launched the new AC-90 Bio multifunctional oil?
AC-90 Bio is one of a number of products under the Green Force platform. We know that tradespeople need tools they can rely on, and that includes sprays. We also know that both the tradespeople and their customers are increasingly aware of reducing their environmental impact. AC-90 Bio was formulated to meet the same longstanding trusted performance of AC-90, but with a readily biodegradable formula (according to OECD 301B >60%) to help reduce environmental impact.
Q
What are the main attributes of AC-90 Bio?
AC-90 Bio is a true multifunctional oil, it displaces moisture, it lubricates, it penetrates and releases, and it protects against rust, as well as being a readily biodegradable formula. AC-90 Bio is also silicone-free, so can be used where surfaces may be treated afterwards.
QWhat is the ‘Green Force’ portfolio of products?
Green Force® is a sustainable (reducing environmental impact through verifiable criteria) initiative bringing together products that meet the growing customer need for reducing environmental impact

and improving user safety, while delivering the premium quality and the high performance that customers expect from Action Can for ‘right first time’ results.
Q How does the 2-in-1 spray system help with application?
Our TwinSpray™ system features two positions: up for precision jet application, and down for a standard spray, allowing the user more control over application. There is a safety stopper to stop accidental spraying and a fixed straw, so you will never be looking around and searching for a lost straw again.
Q Do you have any tips so users can get the most out of AC-90 Bio?
As well as being a multifunctional oil, AC-90 Bio can also be used to clean and remove light rust from surfaces. It can be sprayed onto van door hinges to prevent and stop squeaks and will also protect your tools from dirt and corrosion while not in use.

SAUERMANN SI-CA 130 FLUE GAS ANALYSER WATCH
In this video on the PHPI You Tube channel, Dimitri from Division Gas & Heating takes a look at the Sauermann Si-CA 130 Flue Gas Analyser.
An invaluable tool for heating engineers a Gas Analyser is to be found in tool bags and vans up and down the country. The Si-CA 130 from Sauermann features a touch-screen display and comes with PC-based management software along with a smartphone app for more in-depth combustion gas analysis. The unit also features a magnetic back, so it can be placed directly onto the boiler.
In the video Dimitri runs through the main features of the Gas Analyser, before putting it through its paces on a job.
Amongst the features on the Si-CA 130 are a large colour touchscreen and an eight-hour battery life. Dimitri says: “The eight-hour battery life is more than enough to get me through the week.”
Through the touchscreen users can access all the functions and also create a

customisable home screen so the most used features appear first. Dimitri says: “I can have it exactly how I want it with whatever reading I want at the top of the list. That makes it more beneficial for me, so I can get the information as quick as possible.”
Sensor life
Commenting on the fact the unit indicates the lifecycle of the sensors Dimitri says: “It tells me exactly when it is on the way out so I can plan in the maintenance trip to get it repaired.”
Dimitri continues, “Another key feature I like about the Sauermann analyser is that I can change the filters inside the probe as and when they need to be. It means more time doing a job and earning money.”
Commenting on how easy to use the unit is, Dimitri says: “Overall, really easy to use, can’t knock it at all. Really ergonomic to hold, really lightweight. Eight-hour battery life is top notch.”

VAILLANT’S HIGH RECOVERY CYLINDERS
The high recovery uniSTOR cylinders come in both pre-plumbed and traditional models.
Vaillant has unveiled its new high recovery, slimline uniSTOR cylinder range and accompanying buffer that can be integrated with the cylinder. The complete range will be manufactured at the company’s new production site in Derby.
Available in a full range of slimline sizes, the high recovery uniSTOR cylinders come in both pre-plumbed and traditional models which are suitable for heat pump and boiler heating systems. The company says that for customers not quite ready to move to a heat pump immediately, fitting the new


uniSTOR models now, will allow them to upgrade to a heat pump when the time is right in the future.
New buffer
With this new range of uniSTOR cylinders Vaillant has also launched a complementary purpose-built buffer.
Complete with patented inline technology when fitted with a heat pump, the buffer offers hydraulic decoupling, stores an additional heating capacity to use during peak demand, the functionality to de-ice the evaporator without the need for back up heating and improves the overall performance of the system.
In addition, says the company, the buffer
prevents frequent heat pump compressor cycling to improve the life of the system.
Thanks to its design the new uniSTOR cylinders allow for the buffer to be fitted either at the top or the bottom of cylinder, giving greater install flexibility, especially where space is limited, removing the need to fix onto the wall.
New manufacturing plant
Commenting on the launch Mark Wilkins, Technology & Solutions Portfolio Director at Vaillant said: “With the continued growth in low carbon heating solutions, we’ve recently invested an additional £40m in our manufacturing facilities here in Derby. Our new, state-of-the-art site has been purpose built to manufacture our new range of high-recovery uniSTOR cylinders which complement any heat pump install.
“In addition, the new uniSTOR range can be installed with any Vaillant boiler, meaning homeowners not quite ready to transition a heat pump system, can make steps towards future proofing their homes.”

SHOWERWALL INTRODUCES PLYWOOD COREBOARD
Wall panelling manufacturer Showerwall is now supplying its Laminate collection with either a plywood or exterior grade MDF (EGMDF) coreboard, offering greater choice for customers.
The company says the decision to introduce a plywood option alongside EGMDF was based on customer feedback, giving installers choice over the material they prefer to work with.
The plywood coreboard is available on all Laminate designs in the Original, Impression and Majestic collections.
Also new is a 900mm wide Proclick Laminate panel, suited for use above bathtubs and in larger shower areas. The 900mm panels are said to be easier to handle on a single person installation and reduce the waste generated from cutting 1200mm panels down to size.

Katie Cope, Head of Showerwall, said: “We’re excited to be extending our coreboard choice by launching plywood as standard. We’ve listened to the market and responded – we know that many installers have a preferred coreboard and we want our extensive range of designs to be available on the materials they like to work with. Printing on plywood allows us to preserve the high-quality Laminate designs and textures we’re known for, on a high quality and durable surface.
“Introducing 900mm Proclick panels is also about delivering that attention to detail which Showerwall is known for and allows installers to create a perfectly balanced wallcovering in larger bathroom spaces.”
