A van is at the heart of just about all plumbing businesses Without it, not only would professional tradespeople struggle to get to customers’ premises, but there also wouldn’t be anywhere for many installers to store their tools, products and other essentials.

However, after decades of being powered by petrol or diesel there is a growing call on UK drivers – of cars and vans alike – to switch to electric, thereby minimising fossil fuel emissions

With petrol and diesel vans remaining core components of successful plumbing and heating businesses for generations, is now the time to make the switch to an electric van?

Well, according to a new study by Confused com, 90% of van owners say they would consider an electric van when it comes to choosing a new vehicle for their business The primary reason for the move is a desire to reduce their carbon footprint The study revealed that almost a third (31%) indicated that reducing emissions was the main reason they would consider electric for their next van

However, many potential electric van purchasers also have reservations In the survey over a quarter (28%) of business owners said charging time is a concern, while 13% of respondents indicated concerns about the charging infrastructure in public places (For more on this story please turn to page 7)

Other concerns often raised when people consider shifting to an electric vehicle include journey range on a single charge, the initial cost of an electric vehicle and possible costs if a battery requires replacing

Some benefits of electric vans often cited include the fact they may be easier to drive – EVs have a single speed gearbox, removing the need for gear changes and continuously working the clutch when travelling in heavy traffic Also, the servicing schedule may be lower as they do not have an exhaust, a fuel system and oil or diesel particulate filters

In a similar way to the heating sector, transport must also lessen its reliance on fossil fuels With nine in ten van buyers now considering buying an electric vehicle it would appear that the opportunity to move away from diesel- and petrol-powered vans is opening up

Drayton has surveyed heating engineers, plumbers, electricians, and renewable installers to understand what their customers are looking for from smart heating controls – with Multi-zone smart heating controls coming out on top.

When it comes to the features that are most desired by homeowners, the survey found that a heating control that can be managed via a smartphone app (66%) and a system that offers room-by-room heating control (50%) were the two most common requests that installers were asked for last year.

Energy-saving features – such as smart modes – came in a close third (48%) Additionally, the flexibility to include further connected devices at a later date was desired by just under a third of customers

It is also important that installers are confident in working with the product –according to the survey the most common issue that causes delays on the job was products that are hard to install (64%) Alongside this, product compatibility issues were another top cause of wasted time, cited by 44% of installers.

Merlin Milner, Product Owner for Water-based Systems at Drayton, commented: “The results of our research highlight that in today’s market, customers are prioritising simplicity and convenience; they want the ability to control their heating remotely via a user-friendly app on their mobile and ways to improve efficiency ”

CALL TO ENHANCE GAS SAFETY CHECKS

The Heating and Hotwater Industry Council (HHIC) and the Energy and Utilities Alliance (EUA) have jointly called for the mandatory annual gas safety checks in rented homes to be upgraded to a full service of gas appliances and check on the efficiency of heating systems.

Currently, both private and social rented properties have a mandatory gas safety check to offer protection to tenants The HHIC and EUA believe that upgrading the check to a full service will be good for both the landlord and tenant.

The annual service requires a more in-depth examination of the appliance, making sure it is in good working order, not just safe to operate Enhancing the service further, to include the heating system will mean that the efficiency of the product at warming the home is also considered

Commenting on the call, the Director of HHIC Stewart Clements said: “Upgrading a simple gas safety check to a full service will offer the landlord the ability to make sure the appliance is working properly and checks to see the likely wear and tear, just like a car MOT does. It can identify when an appliance might be coming to the end of its life, giving the landlord time to plan their next purchase

“Tagging on a heating system check will allow the installer to make sure the system is running as efficiently as possible, keeping bills down for the tenant Even checking that the flow temperatures on the boiler are lower can yield significant bill savings ”

Mike Foster, CEO of EUA added: “There are ambitious plans to improve the EPCs of private rented homes, which is welcome, but with a simple upgrade from a gas safety check to a system and appliance service, tenants could save £100s and landlords can plan for the future with greater certainty.

“We support the call for mandatory annual servicing of all heating appliances, but a good first step is surely to upgrade the annual safety check to something even more meaningful ”

90% of van owners say they would consider an electric van when it comes to choosing a new vehicle for their business, according to a new study by Confused.com. The survey also recognises challenges to EV adoption remains, with charging time, purchase price and driving range listed as the top three concerns.

Almost a third (31%) state reducing emissions as the main reason they would consider electric for their next van More than one in four (27%) business owners say that lower running costs associated with EVs would be an incentive to switch. However, over a quarter (28%) of business owners say Charging time is a concern One in seven (13%) also have concerns about there being insufficient charging infrastructure in public places

Rhydian Jones, motor insurance expert at Confused.com commented: “It’s great to see such strong support for electric vans among UK business owners A 90% adoption rate would be a game-changer for businesses and the environment However, concerns around charging times, infrastructure, and costs are understandable.”

SUMMER SERVICE

As the heating season winds down, could summer be the perfect time for installers to prepare for the winter rush? Lee Parsons, MD of Arctic Hayes, explains why proactive servicing reduces breakdowns, boosts efficiency and can help keep customers happy.

Every winter installers face a surge in emergency callouts for heating failures – some of which could have been avoided with earlier maintenance. Landlords and homeowners often overlook servicing during warmer months, only to be caught out when temperatures drop. By tackling essential maintenance during the warmer months, installers can prevent costly winter breakdowns, reduce emergency callouts and maintain a steady workflow throughout the year. With the right tools, servicing becomes quicker, more efficient and ensures customers get the best performance from their heating systems. Here are some areas to focus on...

Boiler Health Checks

Summer provides a perfect window for thorough boiler servicing without the pressure of urgent repairs. A full inspection should include:

● Testing flue gas emissions for efficiency and safety

● Checking for leaks, corrosion, or blockages that could worsen over time

● Inspecting expansion vessels and pressure levels to prevent faults

Using the Arctic Hayes Gas Leak Detector Spray for example, installers can quickly identify leaks around pipework, joints and fittings. This fast-acting, non-corrosive solution can help detect leaks before they become a major hazard in winter.

Gas Safety & System Efficiency Testing

Even during the off-season, gas safety remains a priority. Key checks include:

● Detecting gas leaks with a reliable handheld device, such as the Arctic Hayes Electronic Gas Leak Detector

● Checking CO alarms and ventilation systems in rental properties and older homes

● Measuring system pressure and flow rates to optimise efficiency before the heating is in constant use

These checks ensure compliance and give customers peace of mind that their heating system is safe and efficient before winter arrives.

Radiator & Pipework Inspections

Many heating inefficiencies stem from poor circulation or airlocks in the system. A comprehensive check should include:

● Bleeding radiators and checking for sludge build-up

● Inspecting pipework for leaks or deterioration

● Recommending power flushing if necessary

A simple tool like the Arctic Hayes Radiator Bleed Key makes it easy to remove trapped air, improving circulation and efficiency. One of the most valuable things an installer can do in summer is educate customers on heating best practices. Homeowners and landlords often don’t realise the benefits of running the heating briefly in summer to prevent system seizing. Talk to customers about upgrading to smart controls for better energy management and booking their annual servicing early to avoid winter rush fees. By offering this advice and demonstrating simple preventative measures, installers can position themselves as trusted experts while encouraging repeat business.

Summer servicing isn’t just about preventing breakdowns either, it’s a great opportunity for installers to build a stronger, more predictable business. Encouraging annual servicing plans helps secure repeat customers, while addressing issues in advance reduces the pressure of winter workload peaks.

Offering proactive, efficient service can also set a business apart from competitors, reinforcing expertise and reliability. With the right testing and diagnostic tools, every check becomes more accurate and efficient, improving service quality while saving time on-site.

HARNESSING HOT WATER AS A THERMAL BATTERY

Hot water storage is not just a convenient way of providing hot water, it can serve a dual role as a thermal battery, efficiently storing energy within the home. Kevin Lowe, Technical Manager at the Hot Water Association (HWA), explains how these systems operate as thermal batteries, charging up during periods when energy is abundant or cheaper for later use, thereby optimising energy consumption and reducing costs.

At its core, a hot water storage system functions as a thermal battery by storing heated water for later use. This stored energy can fulfil domestic hot water needs and thermal stores can also be used to provide central heating. Historically, these systems had electric immersion heaters as well as working with gas or oil boilers. However, they can now be integrated with heat pumps, solar thermal panels, and solar photovoltaic (PV) systems, aligning with today’s sustainable energy requirements.

The ongoing development of smart technology for hot water storage means that appliances can be integrated with off-peak tariffs for reduced energy bills and also have the potential to participate in Demand Side Response (DSR), effectively using excess grid energy during peak generation periods.

Types of hot water storage

Vented cylinders These are typically cistern-fed or combination tanks with integrated header tanks. Cistern-fed cylinders rely on gravity from a remote cistern, usually situated in a loft. Combination tanks, while less common, position the cistern directly on top of the water store, though they face limitations due to reduced water pressure.

Unvented cylinders These cylinders are connected directly to the mains water supply, eliminating the need for a

loft-based cistern. This setup ensures higher water pressure and avoids the risk of freezing tanks and pipes in unheated lofts. There are stringent safety regulations regarding pressure and temperature controls that must be adhered to.

Solar thermal and solar PV cylinders

Solar thermal cylinders harness energy from panels on rooftops, with dedicated

This diverse array of technologies means the hot water systems can be tailored to specific energy needs and property types

coils for transferring the heat to the water in the cylinder. For homes with solar PV, a solar inverter is needed to change the direct current to alternating current, then the electricity generated can be used to power a standard immersion heater. If there’s a boiler, the cylinder could still have a coil in it so it can be heated when not enough electricity is being generated.

Heat pump cylinders

Heat pump cylinders have specifically designed large surface area coils to operate efficiently with the lower temperature output from the heat pump. They will also have additional temperature sensing points.

Integrated heat pump cylinders This combines a water cylinder with a heat pump unit, achieving remarkable energy efficiency and often integrating with solar PV for additional sustainability benefits.

Thermal stores The water in a thermal store can be heated by a boiler, immersion heater or solid fuel and is sealed within the system. There can be multiple coils inside to provide hot water for space heating and mains pressure hot water for taps and showers. Mains pressure is drawn through a hot water coil and is heated instantly by the stored water. Because it doesn’t have a large volume of stored hot water, it doesn’t need to have the same controls as an unvented cylinder would have (the coil will generally have less than 15 litres of water in it).

Buffer Tanks A buffer tank is used to separate the space heating circuit from the heating source. On low temperature systems, such as with heat pumps that

need to run for as long as possible, it can keep circulating without having to draw any heat out. The buffer tank is installed in addition to a hot water cylinder that provides domestic hot water.

Diverse technologies

This diverse array of technologies means the hot water systems can be tailored to specific energy needs and property types. With approximately nine million installations across the country, each hot water store has the potential to deliver saving for households taking advantage of off-peak tariffs. And they can even be grid controlled if fitted with at least one immersion heater – most already are –turning them into potential thermal batteries.

THERMAL STORES Q&A

Richard Prince, Business Development Director at Advance Appliances, provides an insight into Thermal Stores and looks at how they differ from standard cylinders.

QHow does a Thermal Store Work?

A Thermal Store works by taking the energy within the cylinder and passing it through an internal coil or heat exchanger to provide mains pressure hot water and water for space heating. A typical store temperature for a Thermal Store would be around 75-80°C, this means that an instantaneous potable hot water supply can be achieved via the coil or heat exchanger without requirements for safety relief valves because of the small volumes of water being heated.

QWhat is the difference between a Thermal Store and a standard hot water cylinder?

A Thermal Store works very differently to a standard vented or unvented cylinder, in those types the water heated within the cylinder is the water which will be supplied to your potable hot water outlets and then replaced with cold potable water from your mains supply. Within a Thermal Store you heat the body of water within the cylinder and use the energy within that water to provide instantaneous potable hot water via an internal coil or heat exchanger.

A Thermal Store can also provide space heating, either via an internal coil or heat exchanger or by using the body of stored

water directly in the heating system, this gives the ability to create either an open vented or sealed type heating system.

Qsolar can be connected without issue and will perform as normal, however on top of this you can utilise almost any additional heat source.

Thermal Store cylinders can accept heat input from solid fuel systems such as log burners and stoves, solar power from either solar thermal or solar photovoltaic, Oil and LPG Boilers and biomass systems to name a few of options available on the market.

Does a Thermal Store require a heat source from renewables or can they work with all kinds of heat source?

A Thermal Store is probably the most versatile when it comes to heat inputs, conventional heat sources such as a gas boiler or an electric source such as PV

Are there any limitations on the number of points of use (taps, baths, etc…) from a Thermal Store?

As a Thermal Store offers instantaneous hot water to taps and showers they can provide hot water for multiple outlets at any one time providing maximum comfort to homeowners. Manufacturers will provide a sizing calculator on their websites and

specification sheets to help size the correct cylinder for the property, this is based on the number of outlets within the property and also the number of occupants.

QWhat kind of flow rates will I get from a Thermal Store?

As a Thermal Store works on mains pressure to provide instantaneous hot water flow rates can be very high in comparison to alternative solutions.

Manufacturers will take into account the size of internal coil or heat exchanger and advise an optimum flow rate for the specific model, this generally sits at around 3 bar and 25lpm in line with an unvented cylinder performance. Like any mains pressure system, flow rates are dependant on incoming mains flow.

QIs any servicing required?

Servicing of any water heater is required to ensure that the system is working efficiently and within safe working parameters.

Manufacturers will generally require an annual service and inspection of the cylinder in line with their warranty. Servicing and maintenance should also be carried out using manufacturers genuine spare parts, as a Thermal Store works under different parameters to a standard vented or unvented cylinder the components used will have different temperature controls and settings.

If you are to replace controls with lower temperature controls you will affect the performance of your Thermal Store. Service intervals and logs are generally found within the back of the manufacturers installation guide and should be kept with the cylinder.

QWhat kind of warranties are available?

Like all cylinders a Thermal Store can be built with different processes and materials and carry a manufacturer’s warranty to suit this, typically a Thermal Store warranty will be between five and 25 years which is standard practice across all cylinder types that we see on the market today.

FAQ

THERMOSTATIC RADIATOR VALVES

Morris, Technical Manager at Altecnic, answers some common questions about Thermostatic Radiator Valves (TRVs).

Thermostatic Radiator Valves (TRVs) are essential components in modern heating systems, providing energy-efficient temperature control for individual rooms. As an installer, understanding the correct installation, operation, and troubleshooting of TRVs is crucial to ensuring optimal performance and customer satisfaction.

This guide is designed to answer the most common questions installers face when working with TRVs, covering installation best practices, system balancing, maintenance tips, and troubleshooting common issues.

Q What is a Thermostatic Radiator Valve (TRV)?

A Thermostatic Radiator Valve (TRV) is a self-regulating valve fitted to a radiator in a hot water heating system. It controls the temperature of a room by automatically adjusting the flow of hot water into the radiator based on the room’s ambient temperature.

Q How does a TRV work?

TRVs contain a temperature-sensitive element, often filled with liquid or wax, that expands or contracts with changes in room temperature. As the room warms up and reaches the desired temperature set on the TRV, this element expands, causing the valve to close and reducing the flow of hot water into the radiator. Conversely, as the room

cools down, the element contracts, opening the valve to allow more hot water in, thereby maintaining a consistent room temperature.

QWhy should TRVs be installed?

● Energy Savings: TRVs reduce overheating and unnecessary energy use, leading to lower heating costs.

● Improved Comfort: They allow room-by-room temperature control.

● Compliance with Energy Efficiency Regulations: Many building regulations require heating systems to be fitted with TRVs.

Installation Advice

Q Where should TRVs be installed?

TRVs should be fitted to radiators in rooms where independent temperature control is beneficial. However, avoid installing them in rooms with a central room thermostat, as this may cause conflicting signals, reducing system efficiency.

TRVs are suitable for most wet central heating systems, including traditional boilers and modern energy-efficient systems.

Q How should TRVs be installed?

● Ensure the heating system is off and depressurised before installation.

● Install TRVs on the flow or return side of the radiator (depending on the model).

● Position the TRV head away from direct heat sources, such as sunlight or electrical appliances, to avoid false temperature readings.

● Follow manufacturer guidelines for fitting and securing the valve.

Q Can TRVs be installed on all heating systems?

TRVs are suitable for most wet central heating systems, including traditional boilers and modern energy-efficient systems. However, they are not typically used in one-pipe systems unless additional modifications are made.

Q How should the heating system be balanced after installing TRVs?

Balancing ensures even heat distribution. After TRV installation:

● Open all TRVs fully and run the system

to reach normal operating temperature.

● Adjust the lockshield valves on each radiator to balance flow rates.

● Ensure no radiators are overheating while others remain cold.

Heat Pump Compatibility

Q Are TRVs compatible with heat pump heating systems?

Yes, TRVs can be used with heat pump systems, but they must be properly set up to ensure efficient operation. Heat pumps work best at lower, consistent flow temperatures, so TRVs should not be used to frequently shut off radiators, as this can disrupt the system’s efficiency.

QHow should TRVs be adjusted when used with a heat pump?

TRVs should be set to maintain steady temperatures rather than frequent on/off cycling. A lower, more consistent setting is recommended to prevent unnecessary strain on the heat pump. Ideally, they should be adjusted seasonally rather than daily.

Q Can TRVs reduce the efficiency of a heat pump?

If TRVs are set too low or fully closed on multiple radiators, the heat pump may

struggle to distribute heat effectively. This can lead to short cycling, where the heat pump turns on and off frequently, reducing efficiency and increasing wear on the system.

Maintenance

QHow can installers prevent TRV issues?

● Ensure the valve and radiator are clean and free from dust and debris.

● Check system water quality to prevent sludge buildup, which can affect valve operation.

What should I do if a TRV is making noise?

● If the TRV is clicking or whistling, check the system pressure and adjust the flow rate.

● Alternatively, check whether the TRV is installed on the return instead of the flow pipe. If the TRV is not bi-directional and is incorrectly placed, it can cause noise.

● If noise persists, reposition the TRV head or ensure it is correctly installed.

How should installers address a leaking TRV?

TRVs contain a temperature-sensitive element, often filled with liquid or wax, that expands or contracts with changes in room temperature

● Check for loose valve connections and tighten if necessary.

● If the valve body is damaged, replacement may be required.

● Inspect for worn seals or washers and replace them as needed.

Common Troubleshooting Scenarios

Q TRV is not adjusting the temperature properly?

● Possible Cause: The sensor element inside the TRV head may be faulty or obstructed.

● Solution: Check that the TRV head is not covered or blocked by furniture or curtains. If the issue persists, consider replacing the TRV head.

Q The TRV is stuck in the open position, causing overheating?

● Possible Cause: The valve pin may be jammed.

● Solution: Remove the TRV head and gently push the pin up and down to free it. If the pin does not move, it may need lubrication or replacement.

Q Radiator is partially warm but not reaching full heat

● Possible Cause: The radiator may be full of sludge or debris.

● Solution: Flush the system and add an inhibitor to prevent future buildup. Ensure the TRV is functioning correctly and allowing full water flow.

Q Frost setting is not activating in cold weather

● Possible Cause: The sensor may be malfunctioning or positioned incorrectly.

● Solution: Check the sensor placement and replace the TRV head if necessary.

By following these best practices, installers can ensure efficient TRV installation, maintain heating system performance, and troubleshoot common issues effectively.

SHARING WARMTH

Radiators are still the main source of heat in well over 85% of homes across the UK and Ireland and radiators work well with lower temperature heating systems such as those driven by heat pumps. All heating systems – not just heat pump driven ones – need to benefit from adequate insulation and radiators need to be correctly sized for each room to deliver comfort heating around the home. That may require larger radiators or radiators with a larger heating capacity – and this is

where new K3 radiators and larger vertical radiators come into their own.

K3s offer three panels and three sets of fins effectively offering 50% more heat than a standard K2 radiator would. So, 50% more heat from the same radiator footprint. The radiator is a little wider and weighs more but will adequately supply heat from a heat pump around the home.

Wall space

Vertical radiators have grown massively in popularity in recent years and many people

prefer them in their rooms as they take up less horizontal space and will fit in nooks and crannies in older homes especially, ensuring sufficient heat whilst not taking up precious wall space.

And, of course, modern radiators can be far better looking than elderly ones and can genuinely be a focal point in a room rather than simply a heating appliance.

Take control

Additionally, the ability to target heat is very simple with radiators via a locally mounted TRV. Temperature control is intuitive and simple. No external wiring, controls or configuration are required.

Additionally, a popular function of heating controls is the one-hour boost. It’s a simple way of countering a cold snap or quickly raising the temperature outside of the normal occupational routine. It is also the ‘go to’ control method for those who find modern controls confusing or who are trying to control costs.

SYSTEM

In order to ensure that each room throughout the home is properly heated, it is important that installers take time to balance the system. Merlin Milner, Product Owner for Water-based Systems at Drayton, explores how this can be achieved with auto-balancing TRVs.

Under Part L of the building regulations, when working on any replacement or new heating system you must ensure that every radiator has TRVs fitted, and that the system is commissioned to be as efficient as possible. This includes system balancing as best practice, which helps improve the overall health of a heating system while also improving efficiency. In fact, system balancing has been found to improve efficiency by 8.8%.

System balancing improves efficiency by ensuring that every radiator around the home receives the correct amount of hot water from the boiler, eliminating cold spots and heating up each room as desired.

On an unbalanced system, the radiators closest to the boiler receive a larger flow of hot water and heat up quickly, whereas the radiators further away from the boiler –perhaps upstairs or in the far corner of the property – receive a lower flow of hot water and therefore lead to cold spots forming around the home.

Consequently, an unbalanced system often tends to result in homeowners having to turn up the thermostat to try and heat all rooms to the desired level, which means higher energy consumption and increased energy bills. With comfort levels not being met, this will inevitably lead to call backs, which no installer wants.

How to balance a system

The most common way to balance a system is by using the lockshield to limit the flow rate to each radiator. However, this approach is very inaccurate, and settings can be

tampered with by homeowners or decorators when isolating the radiator for removal Historically, due to the complex and time-consuming nature of system balancing using lockshields, this step was often not carried out

Alternatively, you may have used pre-setting TRVs, such as the Drayton TRV4, which thanks to the balancing key, allows you to balance the flow rate on the TRV valve body itself.

However, there is now auto-balancing technology available in TRVs to make this process even easier and provide permanent system balancing This technology can be found in Drayton’s TRV4 and RT414 ranges and takes just a few minutes to set up Here’s how it works

Fitting the Drayton auto-balancing TRVs

1 Before fitting Drayton’s Auto-balancing TRV, you’ll need to check the output size of the radiators within the system you’re working on If you’re fitting new radiators, this information should be readily available.

2 Once you know the output size of the radiators, refer to the setting table provided on the box of the Drayton auto-balancing TRV to select the required temperature difference across the radiator; this will then tell you the value that the valve needs to be set to.

KEY OR KEYLESS

Steve Harris, Technical Support Engineer at Wavin explores the different push-f it f ittings on offer across the plumbing market and how installers can make an informed decision on which products to opt for.

Push-fit fittings have revolutionised plumbing and within this category keyless fittings take efficiency a step further by removing the requirement for a demounting key, instead using a ‘twist and push’ mechanism This innova provides faster, hassle-free installations which is particula valuable in confined spaces li sinks or behind cupboards, wh handling additional tools can s process

Recent advancements in k technology, such as Wavin’s K Hep2O range, have refined th further improve convenience

fittings ensure they are ready to install straight out of the box, eliminating the need for preparation in turn reducing overall installation time. At the same time, features like Wavin’s In4Sure technology provide clear visual confirmation of a secure connection, giving plumbers confidence that fittings are correctly installed

the choice between key or keyless systems should ultimately boil down to a personal preference

However, while keyless fittings are making strides, key-operated push-fit systems remain a trusted, reliable offering. Many installers value the additional layer of security that comes with using a demounting key, particularly in installations where fittings need to remain tamper-proof These systems continue to be a reliable choice, offering peace of mind for both allers and end users

ancing speed and reliability ciency in plumbing extends beyond just allation speed durability is equally as ortant A fast connection is only neficial if it also provides long-term ability, preventing costly leaks and mantling or replacement further down line

Early concerns about keyless fittings en centered around security, particularly with questions around whether they could remain secure over time However, modern designs have addressed these issues Newer keyless fittings now feature tamper-resistant designs, reducing the risk of accidental disconnection Even if

unlocked, advanced systems like Wavin’s Hep2O Keyless remain leak-proof and will not detach unintentionally.

Additionally, both key and keyless push-fit fittings benefit from the advantages of plastic piping systems Polybutylene plastic is cost-effective, flexible and lightweight, making installation easier and reducing strain on plumbing networks

Importantly, installers aren’t forced to choose one system over another Wavin’s push-fit fittings, for instance, are compatible with copper pipes, giving professionals the freedom to integrate plastic fittings within existing copper systems

Efficiency in plumbing extends beyond just installation speed—durability is equally as important

ever, requiring solutions that maximise productivity while maintaining high standards.

Collabration

At the heart of these innovations is collaboration. Manufacturers like Wavin work closely with plumbers to refine product designs, ensuring that new developments address real-world challenges By combining ease of use, reliability, and adaptability, modern push-fit solutions are equipping the industry with the tools it needs to move forward

Meeting industry challenges

As the demand for new homes and infrastructure continues to rise, the plumbing industry faces increasing pressure to keep up the pace. Government initiatives to build 1.5 million homes mean skilled plumbers are more in demand than

Both key and keyless fittings offer valuable solutions to this challenge While keyless fittings provide speed and convenience, key-operated systems offer additional security, making it essential for professionals to have access to both options The key to success lies in flexibility – and the choice between key or keyless systems should ultimately boil down to a personal preference

For those looking to enhance efficiency without compromising security, the choice between key and keyless fittings is no longer a trade-off It’s a matter of preference And with continuous advancements in push-fit technology, both options are proving to be indispensable assets for modern plumbing

PLUMBING & BATHROOMS

SPRING BATHROOM TRENDS

Spring is a popular time for homeowners to invest in bathroom renovations – and installers are more involved in the design process than ever before. So, what’s in demand for spring and beyond? Rochelle Barratt, Channel Marketing Specialist at hib explains.

This season’s bathroom trends strike a balance between individuality, comfort and modernity. hib’s newest collections have been developed with four key trends in mind – each offering opportunities for installers to upsell based on style, finish, and functionality.

1. Warm Minimal

Soften traditional minimalism with natural textures, warm tones, and soft lighting, creating a calming, inviting space. Inspired by Mediterranean interiors, it blends open, light-filled design with organic materials for a rustic yet refined aesthetic. Gentle curves and earthy hues add warmth, making the space feel serene and personal.

How to deliver it...

The Arbor Mirror perfectly embodies this trend, bringing the beauty of natural wood into the bathroom without impacting the forests that inspire it. With soft LED illumination and ambient lighting, Arbor enhances the space with both warmth and functionality. Available in Archdale and Bowthorpe finishes, it completes the look with a sense of natural calm.

Style Suggestion: Combine with a neutral-toned furniture like the Sierra for seamless, tranquil design.

2. The New Luxe

Modern luxury isn’t about gold taps and chandeliers, it’s about thoughtful design, soft ambient lighting and a clean, considered palette. Homeowners are looking for bathrooms that feel like boutique hotel suites: smart, elegant and functional.

How to deliver it...

Suggest statement pieces like the Ionic Pill Mirror, with its sleek pill-shaped design, colour-adjustable LED lighting, and touch switch controls. The soft illumination and contemporary finish to the mirror bring a refined elegance to any space.

Complimentary pieces like the Harper basin add the perfect finishing touch to a bathroom, available in four striking finishes – Chrome, Black, Gold and Bronze – to elevate the space. The metallic edge detailing adds visual interest without overpowering the room.

Upselling tip: Many customers don’t realise how much difference ambient lighting makes. Demonstrate lighting temperature changes and talk about how it can transform the room at different times of day.

3. Modern Retro

This playful trend reintroduces nostalgic shapes and colours in a modern setting. Think pill-shaped mirrors, curved corners, mid-century influences and a touch of personality.

How to deliver it

The Odelle Coloris Cabinet is a perfect fit for the Modern Retro trend, combining design with customisable details Its 14 interchangeable trim finishes allow homeowners to create a unique statement, whether they prefer muted taupes, stone shades, or bold metallics Odelle balances retro charm with modern innovation

Pro tip: Installers can highlight how this level of flexibility makes it easy to futureproof the design Want to update the look in a year or two? Simply swap out the trims instead of replacing the full unit

4. Light Industry

Industrial design is still going strong, but it’s evolved into something lighter, more refined, and more home-friendly Rather than harsh concrete and raw steel, today’s industrial looks are warmer and more versatile

V isual aids can make a big difference too –whether that’s finish samples, a product brochure, or photos of previous installs

How to deliver it

Black is your building block here. The Romana Pill in black makes a bold statement with its striking design being pill and arched shaped and colour – changing LED illumination adds both elegance and modern sophistication

Pair with the Madox tap range, available in five trend-led finishes, to bring an industrial edge without looking stark Its solid brass body, smooth ceramic cartridge and waterflow aerator offer function and flair.

Installation insight: In hib’s Installer Trends

Survey around 65% of bathroom installers say their customers now ask specifically for coloured or metallic brassware – so having options on hand makes upselling easier

Upselling with Style

Beyond fitting the products, you’re often the expert homeowners look to for guidance Upselling doesn’t have to be a hard sell; it’s often about having the confidence to recommend something that adds real value

Homeowners don’t always know what’s possible, so when you suggest a cabinet that combines clever storage with standout style, or a tap finish that complements their tiles perfectly, they’re far more likely to trust your guidance and invest a little more

Visual aids can make a big difference too – whether that’s finish samples, a product brochure, or photos of previous installs – as it helps clients to picture how the space will come together

It’s also important to highlight the practical benefits behind the design A heated mirror pad that prevents fog or lighting that can be adjusted for different times of day isn’t just a ‘nice extra’, it’s a smart, useful feature they’ll appreciate every single day

And finally, flexibility is key Products such as Odelle Coloris, with its customisable trims, make it easy to tailor a bathroom to the homeowner’s tastes and give them the option to update the look in future without the need for a full refit. Small details like this can turn a good bathroom into a great one and give you the edge as an installer who knows both style and substance

Trusted advice

As bathrooms become more design-focused and more connected to the wider aesthetic of the home, homeowners are turning to trusted installers for design input Whether it’s selecting the perfect mirror, mixing finishes or choosing storage that works for their lifestyle, your advice matters

By staying up to date with trends and offering the right blend of style and substance, you can help your customers create beautiful, functional bathrooms that feel truly their own And that means more satisfied clients, more referrals, and a stronger business for you

A TIGHT SQUEEZE

By equipping themselves with tools designed specifically for confined working conditions, plumbing and heating engineers can work more efficiently, reduce strain and maintain full control, no matter how tight the workspace, says Jason Cunningham, Product & Technical Support at KNIPEX.

As a plumber or heating engineer, it’s not unusual to find yourself working in confined or awkward spaces.

Whether it’s adjusting pipework in a tight service void, tackling a stubborn fitting in a plant room or navigating the layout of a heat pump installation, accessibility can be a major issue. Many installations and repairs take place in environments where space is severely restricted, making tool choice a critical factor in getting the job done well.

Underfloor heating manifolds, for example, are often tucked away inside compact cabinets or utility spaces where clearance is minimal. Similarly, working behind boilers in kitchen cupboards or airing cupboards can leave little room for manoeuvre, especially when dealing with pipe connections or servicing components. In older properties, where pipework runs through floor voids or behind walls,

engineers may have to work through small access hatches and in commercial settings, plant rooms are frequently packed with pipework, valves and equipment, forcing engineers to work at awkward angles.

In these situations, having the right tools is essential for efficiency, control and to reduce strain on the user. KNIPEX has developed a range of tools designed to perform in tight spaces without compromising on grip, strength or adjustability. From the Cobra® QuickSet series to the Cobra® XS and Mini Pliers Wrench, these tools help engineers work more effectively in restrictive environments.

Speed & convenience

The KNIPEX Cobra® QuickSet range is designed for speed and convenience while maintaining a strong grip. Traditional water pump pliers use manual adjustment to give precise control over each gripping position,

Choosing the right tool for the job can make a big difference when working in restricted spaces

ideal for those who prefer a measured approach. But when speed matters or you’re in a particularly tight or awkward spot, the Cobra® QuickSet offers a faster alternative. Simply open the pliers completely, set the jaws on the workpiece and push the pliers’ handle to find the right gripping size – the hinge bolt then engages and the gripping width of the pliers is firmly set until the push button is pressed. The self-locking jaws grip securely onto the workpiece, preventing slipping and allowing for efficient torque application. The

compact head design adds to its usability in restricted spaces, making the Cobra® QuickSet a practical choice for plant rooms and service voids where repositioning a tool repeatedly can be frustrating.

The range includes three models, each offering the same push-to-slide adjustment but differing in size and capacity. The 87 21 250 is a versatile mid-sized option with a 50mm gripping capacity, while the 87 21 300 provides extra reach and power with a 60mm capacity. The 87 22 250 features a multi-component comfort grip for improved handling, making it suited to prolonged use in challenging conditions.

One-handed operation

For times where even a 250mm tool is too large, the KNIPEX Cobra® XS is a compact, powerful alternative. At just 100mm in length, it is suited to intricate pipework, under-sink installations and other tight spaces commonly encountered in modern plumbing systems –particularly as you can operate it with just one hand. Despite its small size, it has the same self-locking grip as its larger counterparts and offers 11 fine adjustment positions for precise handling of pipes and fittings up to 24mm in diameter.

Precise control

When working on delicate fittings or in confined areas where precise control is required, the KNIPEX Mini Pliers Wrench is an essential tool. Measuring just 125mm, it provides the functionality of both a wrench and pliers in a compact form. The smooth, parallel jaws distribute pressure evenly so it can be used on brass fittings or other sensitive materials without causing damage. Unlike traditional adjustable spanners which can round off edges, the Mini Pliers Wrench allows for firm, non-damaging grip. Its ratchet-like action means that once engaged, it can tighten or loosen fittings quickly without the need for constant repositioning. The small size and ergonomic design reduce user fatigue, so it’s ideal for extended use in challenging working conditions.

Choosing the right tool for the job can make a big difference when working in restricted spaces. The Cobra® QuickSet models offer quick adjustments and a firm grip, the Cobra® XS is great in ultra-tight environments and the Mini Pliers Wrench delivers precision and damage-free handling of delicate fittings. By using tools designed specifically for confined working conditions, plumbing and heating engineers can improve efficiency, keep control and complete tasks with greater ease.

GIMME FIVE

PHPI catches up with the latest product in the PipeSnug and FlueSnug range – the FS5.

Back in 2017, PHPI reported on the launch of PipeSnug, a pipe seal invented by PHPI reader Chris Burdett. Since then, the brand has gone from strength to strength and when Talon took on the product range it promised new products – and the company has now delivered, in the form of the FlueSnug 5” (FS5).

When retrofitting heating systems, a familiar set of challenges often present themselves: drilling new flue holes, sealing around pipework and compliance with Part L of the Building Regulations. It can be time-consuming and messy and older buildings in particular present difficulties, as they weren’t designed with today’s airtight, energy-efficient standards in mind.

Pipe seals

Gaps around pipe penetrations allow warm air to escape and cold air to filter in, forcing heating systems to work harder often presenting increased energy bills for homeowners. Installers have, in the main, relied on mortar, silicone or air-sealing tape to seal around flue pipes, but these traditional methods come with drawbacks. Plus, Part L now mandates the use of pipe seals and grommets to reduce air loss and improve insulation.

“One of the most frustrating aspects of retrofitting a boiler is getting the flue to align with the existing hole; if the new flue is even slightly off, it often means having to drill out a larger opening or use filler to compensate which means extra time, effort and cost. This is where the ‘FS5’ comes in,” explains Dean Heathfield, Commercial Director at Talon.

“Firstly, there is no more core drilling hassles as installers try to modify a hole – the FS5 is precisely sized to fit the existing flue opening, making flue replacements faster, neater and fully compliant with the latest building regulations. Installers can simply slot the FS5 into place and quickly secure the new flue without the need for mortar, sealant or patching, speeding up installations and reducing disruption for both the installer and the homeowner.”

Professional finish

Under the latest Part L regulations, all new boiler installations must have properly sealed pipe penetrations to prevent heat loss, achieved by using collars or grommets. Talon says fitting the FS5 means installers easily meet these regulations by providing a tight, durable seal around the flue, helping maintain the building’s

energy performance while keeping installation times to a minimum

“A clean, professional finish is a hallmark of quality workmanship, leaving a lasting impression on clients and ensuring a job well done,” continues Dean

“Gaps, rough edges and visible patchwork can make even the best installation look untidy, which is why finding the right solution for sealing flues is essential The FS5 helps installers achieve a clean, high-quality finish; there’s no need for core drilling or resizing holes, filling in gaps with mortar or sealant or touching up or repairing wall surfaces Instead, the FS5 just leaves a neat, professional finish with no mess or waste.”

Boiler flues need regular inspections and servicing to ensure they are working safely This is made simple with the FS5 as it can be removed and replaced without damaging the seal

TECH TIPS #2

Wetroom tanking

Tanking a wetroom will prevent water and humidity from penetrating the walls of the showering area and ensure leak-free showering.

Wetroom manufacturer, Impey, says...

Tanking membrane

Tanking membrane is a thin, flexible, self-adhesive waterproof tanking system, which provides a barrier against leaks. Look out for a solutions offering:

● Decoupling properties

● No curing time

● Compatibility with powdered flexible wetroom adhesives and grouts

Installation process

[NB. Any installation should be carried out with full reference to the manufacturer’s instructions]

1. Prep the area

Good preparation will help to ensure that you achieve the best results. The floor structure needs to be prepared following the relevant British Standards before tiling. To prepare the room for tanking:

● Clean and dry the floor and work area

● Remove any sharp protrusions

Impey’s WaterGuard tanking kit includes a primer, to apply to all porous surfaces that will be covered by the membrane.

2. Corners

Once the primer has dried, fit the preformed corners. Remove the backing covers one at a time. Gently guide the adhesive surface onto the floor-to-wall junction and smooth over.

3. Jointing Tape

Using jointing tape provided, line all wall-to-floor and vertical junctions with tape. These locations should always be taped regardless of whether installing on walls or floors.

4. Application of Tanking Membrane

Tanking the wall first reduces the risk of damaging the floor membrane. Please www.rdr.link/pbn038 to see a video which illustrates the whole process.

Top tips

● Position the edge of the tanking membrane in line with the centreline of the vertical tape

● Gradually remove the release paper

● Ensure there are no air bubbles in the membrane

5. The Drain Aperture

Locate the drain aperture and the inside edge of the cutting guide. Cut the membrane around the guide and press it into the drain bowl. Replace the clamping ring and screw down. Tighten the screws by hand.

6. Sealant

Apply sealant to gaps between the membrane and wall-to-floor junctions.

7. Tiling

Impey’s WaterGuard membrane can be tiled on straight away.

RIDGID FLEXSHAFT

Whether it is in residential situations or commercial buildings blocked drains can be highly problematic Consequently, when cleaning and/or unblocking a drain, installers need a quick and efficient solution that leaves the pipes clean and free flowing

All FlexShaft machines utilise a flexible shaft that can not only bend, but also still rotates. The company says that the fact it rotates within an outer sheath makes it also safer and cleaner during operation, as the hands don’t touch rotating cables and debris isn’t thrown around while doing a clean-out

Additionally, because the cable rotates within the sheath, FlexShaft machines also enable the simultaneous use of a camera while performing the drain/pipe cleaning job which can prove to be a t time-saver

Portability

One of the primary advantages of the two small FlexShaft machines is portability The K9-102 weighs about 11 kg, while K9-204 weighs 17 kg FlexShaft machines are powered by a widely used 18-volt battery-powered drills

there’s no need to deal with power cords. Plus, all machines come with two chain knockers that expand as they rotate to clean the entire circumference of a pipe

The latest addition to the FlexShaft range is the K9-306 featuring 38m of 10mm cable It’s less playing in the portability field, but more playing in the power field –the machine weighs around 72kg.

Accessories

The benefits of using a chain knocker in the cleaning process is that the chains expand due to the high-speed rotation and centrifugal force, allowing grease and sludge to be hit off the walls of the pipe, rather than poking a hole in the blockage

The selection of the correct tool for the blockage remains crucial

WIN!

To be in with a chance to win a K9-12 FlexShaft Drain Cleaner please scan the QR code

With many drainage systems needing occasional maintenance, PHPI takes a look at the FlexShaf t drain cleaning machines from RIDGID

for success. RIDGID has a wide range of chain knockers and brushes suitable for different types of blockages and different types of pipe material

A chain knocker with smooth chains can be used for soft blockages, such as grease and soap A chain knocker with carbide tipped chains is much more aggressive and can be used for tougher blockages such as limescale and uric scale build-ups. Also, light roots can be tackled best with these type of chain knockers However, as their action is much more aggressive the company recommends users to be very careful while using these chain knocker types in softer pipe materials, such as PVC

FlexShaft can also be combined with brush add-ons These brushes, both nylon or nylon/steel, can be used as a cleaning action after a chain knocker cycle or simply as a cleaning tool in the more fragile pipe types

TALON

FS5 FlueSnug

Talon’s new FS5 (FlueSnug 5) promises to make sealing existing flues easier and in this video Chirag takes a look at the new solution. Commenting on the new FS5 Chirag says: “I like the fact you can use the FlueSnug both externally and internally. There’s no mess, it is quick and easy to install and, most importantly, it conforms to all the regulations.”

He continues: “This FS5 FlueSnug is an absolute game-changer because it means that now, when I am just changing a boiler over in the same position, I haven’t got to worry about re-coring a new flue hole because the 127mm core hole allows the FlueSnug, the new one, to literally just slot straight in.”

To watch the video… www.rdr.link/pbn047

In this video Angelo, from Division Gas & Heating, installs the Caleffi XS under-boiler magnetic filter. The Caleffi XS features small dimensions, making it suitable for tight spots under boilers – which is where Angelo installs the filter during the video. He notes: “You have only got two 22mm compression joints to actually connect onto. There is no need for any isolation points either side because of the built-in isolation point and everything is built into one unit, so it saves you time, saves you money.”

Angelo concludes that the compact size of the unit is one of his stand-out features, noting: “I know I’ve come across many boiler installations where a kitchen fitter has come in behind us and really closed the boiler off, so if you are retrofitting this filter, it is going to save you a lot of time, a lot of effort.”
