PROFESSIONAL HEATING & PLUMBING INSTALLER is a business journal for those involved in the installation, maintenance and repair of heating and plumbing systems. It is available to the trade at leading heating and plumbing merchants and specialist outlets throughout the UK.

Show and tell

Earlier in the summer thousands of visitors descended on the NEC in Birmingham for the InstallerSHOW event. With around 450 companies exhibiting their latest solutions and services for the sector, along with an array of talks and seminars – and some great interactive challenges and entertainment – the three-day event was an opportunity for the sector to come together and focus on some of the challenges facing the industry.

Throughout the event a number of topics seemed to be repeating themselves. One was the desire for information and training on the latest products. Described to us during more than one discussion as an ‘educational piece’ this came as little surprise, bearing in mind the speed with which technologies such as heat pumps, hybrid systems and smart controls are entering the market.

As the sector continues to move in this direction installers increasingly require support, training and advice on working with these technologies. It was reassuring to find many manufacturers focusing not only on their own products, but also on getting knowledge of these new technologies across to installers.

Another subject that many seemed keen on discussing was sustainability. A broad topic, and one which appears in different ways depending on who you are speaking to, but this too is a growing driver for the sector.

Many manufacturers were highlighting how solutions have higher levels of recycled content, reduced packaging, or are more easily recycled. Other products can reduce water usage or help consumers cut energy use – both increasingly critical points for many consumers.

Support for installers with promotions and installer schemes was also evident. Such schemes – usually based around collecting points for purchasing products before redeeming them for free training or additional products or gifts – are well-known within the sector. They appear to be being adopted by an increasing number of manufacturers seeking to further support installers in a competitive market.

And, for us, perhaps the single over-arching feeling that dominated the event was opportunity. The sector is evolving and changing. Heating sources are becoming more diverse. Energy and water saving are high on consumers’ wish-lists, who are becoming more engaged with environmental concerns.

Professional plumbers and heating engineers are well-placed to deliver for customers who are in need of skilled tradespeople equipped to provide not only solutions but also trusted advice.

DAIKINLAUNCHESINSTALLER INCENTIVESCHEME

Daikin has introduced a national Installer Incentive scheme, rewarding MSC certified installers with £250 each time they fit a Daikin air source heat pump in England, Scotland or Wales.

The scheme is directly linked to the Boiler Upgrade Scheme (BUS) and the Home Energy Scotland Scheme (HESS). MCS certified contractors who install eligible products under either BUS or HESS will receive the £250 cash incentive. In England and Wales the eligible products are Air Source Heat Pumps (ASHP). In Scotland both ASHP and Hybrid boilers are part of the scheme.

Commenting on the offer Henk van den Berg, Daikin’s Head of Residential Business said: “The £250 incentive is yet another reason for already accredited heat pump installers to choose Daikin’s award-winning range of air source heat pumps for their customers, and the offer will be particularly attractive to gas installers who want to expand their business into renewables too.”

MODULAR RACKING

QWhy has Rhino Products decided to introduce an Internal Racking solution for vans?

Here at Rhino, we’re all about innovation, and after building a reputation as a leading manufacturer of products such as roof racks, roof bars, and pipe tubes, in many ways this was the next logical step. The launch of MR4, our first ever internal van accessory, coincides with our 20th anniversary - over the span of two decades, we have expanded into seven companies, two factories, and multiple distribution centres. Despite our growth, we have always stayed true to our roots with the tradesman in mind – you keep the world moving.

QHow does the MR4 system help to maximise storage space in the back of a van?

Our dedicated team of designers have mapped out every vehicle to ensure that all configurations are made to measure, to maximise the potential storage space of every van. People who have bought Rhino roof racks or bars in the past will be familiar with our bespoke fitting kits which help tailor the products to the specific mounting points of each vehicle. The same goes for our MR4 range, we supply unique fitting kits with easy-to-follow instructions that tell you how to assemble and fit the racking.

QWhat kinds of storage options and accessories are available?

Our standard shelving range is already available to purchase online, with sleek aluminium fronted drawers being added to

the range soon. Also in development are drop fronts, kickplates, lockers, and assortment box systems. Several optional accessories are currently available for the MR4 range, with many more additions on the way. We now offer ‘lin bin’ storage tubs that easily slot into your shelving, with the option of purchasing dividers to section off areas within the bins. If bins aren’t your style, we also offer steel shelf dividers that can be placed anywhere along the shelf to suit your needs. To hold your tools and equipment in place without moving

around in transit, we also offer rubber matting to line your shelves with an extra bit of grip. Our lin bins and shelf dividers are designed to slot in at any point along the shelving, meaning you can customise your MR4 system however you need.

QCan a professional tradesperson fit the system or does it need to be done by a specialist?

No specialist needed. MR4 is designed with tradespeople in mind - we know that time is one of the most important resources you have, so we made sure that fitting is quick and simple. Each kit comes with an easy-to-follow set of instructions, showing assembly and fitting, telling you exactly where to drill. The bespoke fitting kits with innovative blind-bolts and self-fixing tek screws have been cleverly designed to make fitting an MR4 system as quick and easy a process as possible. With our system, anyone can fit it with speed and ease, meaning you can get moving again quickly.

MR4 is available to buy online now, but if you would rather have someone fit it for you, the range will soon be available through our nationwide network of fitters.

PUTA FREEZE ONIT

PHPI chats with Freeze Master, to get the company’s view on the benefits of pipe freezing and how installers can go about it.

QWhat is pipe freezing?

Pipe Freezing is a method that allows you to isolate, remove and fit a new part in a system without the need to drain down. There are, or were, methods of performing such a task by using gases, specifically CO2 tanks or aerosol spray cans.

Using our ‘Freeze Master’ Machine, you can select a specific area of a pipe, connect the purpose designed ‘Freeze Heads’ to the pipework, then it will create what we call an ‘Ice Plug’. After that work can be done on the problem area without any fuss, mess or risk.

QIn what kinds of circumstances would plumbers typically consider using it?

Plumbers and engineers would use pipe freezing to isolate a problem and then repair or replace the part that’s causing the problem. They would usually go this route when they are unable to locate the stopcock or full bore valve to turn off the water supply as well as to avoid draining down the pipes. Heating engineers would use this solution to replace or fix radiators, fire sprinklers and valves as it can save a lot of time and is much easier than other alternatives.

In a lot of cases a stopcock or full bore valve is used to operate the water for an entire building (e.g. a block of flats or an office building) this would mean that you would have to turn off the water supply for the whole building just to fix one small problem, but you can avoid

this by freezing the pipes instead. Another common circumstance that may force plumbers to undertake pipe freezing would be the condition of the stopcock itself as it is not unusual to find stopcocks in poor corroded conditions and rendered unusable.

QWhat are the benefits of taking this approach?

The main positives for pipe freezing are that it saves a lot of time and energy compared with the alternatives, which leads to saving money. Often when some pipework needs to be repaired, plumbers or engineers need to weigh their options and come up with the best solution. However, pipe freezing can be used to isolate and repair almost any problem.

By using our ‘Freeze Master’ Machine, you can save time, money and energy minus the risks that come with using aerosol spray cans and minus the inconvenience of turning off the water supply. Freezing a pipe with our machine is as easy as connecting the ‘freeze heads’ to the pipe and turning it on. It can take as little as 6-8 minutes, while locating a specific stopcock or a full bore valve can be difficult, and in some cases impossible especially in older buildings.

The machine was developed to be a portable, electric and motorised refrigeration system that would freeze pipes for an indefinite period. This means while it’s freezing you can prepare your other tools/equipment as there’s no danger of the ice melting and flooding as long as the machine is on and connected to the pipe.

Additionally, the machine is a sealed system so no gas is expelled and the gas is continually recycled and reused. As long as it is maintained well and there’s no leakage detected, there’s no need to refill the machine and there’s no additional costs on top the more you use it. This of means it’s much more environmentally friendly than other methods.

QAre there any factors/issues that plumbers should pay particular attention to when considering this option?

As most people working in this kind of industry would know, certain risks would be involved by using ‘conventional’ methods. There’s also no real way of knowing how long a job may take and one big risk would be that a gas bottle/can/tank could empty out in the middle of a job.

Another issue is whether it would work on certain types of pipes. It’s important to know that gas kits would find it difficult to freeze pipes with high pressure water. There’s also a chance it could cause damage to the pipes as attempting to freeze pipes with high water pressure could cause flooding.

Our machine eliminates the risks and remedies the problems. No gas is

discharged from the machine as it is recycled and reused over and over again –it is essentially like buying an endless source of gas canisters. No damage will be caused by it and it works on almost any type of pipes including copper, iron, lead and plastic ones. It should also be noted that it can handle a water pressure of up to 100 bar (1500 psi).

QWhat equipment is needed to freeze pipes?

With our Freeze Master machine, all you really need is the machine itself. It’s safe, easy, mess free and quick. The machine is also relatively light and portable and is fitted with all the add-ons needed to adjust it for different sized pipes.

HIGH PRESS

Whilst traditional jointing methods still have their place in the market, there’s no doubt that the popularity of press fittings has increased dramatically in recent years.

There are a number of reasons for this, mainly the speed of installation, which can make the completion of a job up to three times faster. Press is also a much cleaner installation process, and there’s the fact that installers don’t have to obtain a hot works permit, which can save considerab le time and money.

Another factor for the increasing use of press fittings, particularly 3-point press variants like Conex Bänninger’s >B< Press range, is the added layer of security and peace of mind for the installer that joints will be pressed correctly.

A key advantage of press fittings over traditional methods is the ease and simplicity of installation, although this doesn’t mean that it can be done without the right training. It is vital installers are up to speed and undertake the necessary training to ensure they are confident and competent installing the fittings.

Pressure testing

Whatever the size of the project an installer is working on, there’s always the possibility that a joint hasn’t been pressed properly. This is one of the reasons why pressure testing a system is so critical.

By filling the system to atmospheric pressure first and visually checking all the joints, it means all unpressed fittings can be identified and crimped effectively to avoid any potential issues in the long term once a system is running at normal pressure.

Using a fitting that is specifically designed to leak if the joint hasn’t been crimped correctly is a great fail-safe

provides some tips and advice on press fitting and outlines why training is paramount to ensure systems are installed correctly.

measure. It gives installers added peace of mind and the opportunity to check all the joints and go back and press any that might have been missed.

Joints are occasionally missed by accident, for example, it might be that an installer is distracted with another job and this takes them away from where they are at. Or it could be as simple as having to change the battery in the press gun and going back and missing a joint. This is why using fittings that are designed to leak and highlight any fittings that haven’t been crimped properly is essential.

There are also cases though where press fittings aren’t being installed correctly in the first place.

It may be that an installer is using the wrong type of jaw profile to press the fitting, for example, such as an M Profile jaw instead of a B or V Profile jaw, or the tube hasn’t been correctly prepared or inserted fully to the right depth. This is what makes training so important.

The right approach

It is vital that installers follow the basic procedures for correctly installing a press fitting to ensure a reliable and leak-free joint. Choosing the right tool for the job is vital in order to achieve accurate and secure press fitting.

First, you need to choose the size of the tube and cut this to size with a proper pipe cutter. Next, the tube needs to be deburred inside and outside to ensure no debris is left in the pipework and it has a smooth finish. Then, using a depth gauge or the fitting socket, simply mark the depth of the fitting with a marker pen. This gives a visual guide that the tube will go into the socket at the correct depth. Once the tube has been marked to the correct depth, take the fitting and put it into the jaw. Press the joint using a press machine for the perfect joint.

Free training

At Conex Bänninger, we understand the importance of providing installers with the right level of training to ensure they can fit our products to best practice standards. All of the training we provide is offered to installers completely free of charge, either at our training centre or we will also come to site as many times as required to undertake training sessions to ensure all installers on a job have the necessary skills to press-fit correctly.

Everyone that goes through our training receives a certificate to prove their credentials, which many sites are now requesting to see as standard to try and regulate the level of professional they allow on-site. We provide certified ID cards that an installer receives once they have completed their press-fit training as part of our commitment to add value to our customers’ businesses.

Finally, we are also investing heavily in our training offering at our head office in the West Midlands, creating a Training Centre of Excellence where installers can come and spend time with our expert industry trainers on a host of courses to keep up-to-date with the latest trends and innovations in the HVAC fittings industry.

Sealant SELECTION

While sometimes overlooked, choosing the right sealant products is essential to the overall finish of a bathroom installation. Here, Andy Cummins, Senior Product Manager at Geocel, outlines what is available and explains what professionals should look for.

As any tradesperson will understand, the use of low quality products, even for the seemingly smallest elements, has the potential ruin an otherwise professional installation. For example, the use of a poor quality sealant, or one that is not designed for the task, can have a significant impact.

Poor quality sealants in bathrooms can lose adhesion and fail, sometimes after just a short time, or quickly become stained with mould and mildew. This will lead to call-backs and customer dissatisfaction with the work, plus a risk of water seeping into areas where it shouldn’t be and causing damage. For businesses that rely on positive word of mouth recommendations to attract new customers, this is a serious issue.

With so many sealant options available it can sometimes be difficult to know which is the right product for the job and different areas of the bathroom will often need a specific type of sealant.

Sealants for wet areas

One of the major areas of any bathroom job where a quality product is required is for sealing around sinks, baths and showers. Here a silicone sealant is ideal as these generally offer good adhesion on a wide range of non-porous surfaces such as plastic, glass, ceramic, porcelain and most metals. Silicone products also offer good elasticity

as well as UV, water and temperature resistance. The permanent flexibility of a good quality silicone sealant means that it will accommodate movement of the joint without losing adhesion. It is also worth looking for a product, such as Trade Mate Sanitary Seal, that is specifically designed for wet areas and includes an effective fungicide to resist unsightly mould growth.

Where there is a need to seal around an area that includes porous surface materials, such as stone, marble or granite, a neutral silicone sealant should be used. This type of product, which includes DOWSIL 785N, will perform the same role as other silicone products but will not stain the surface of the material – providing the ideal solution for both porous and non-porous sanitary surfaces.

Sorting gaps and cracks

When taking on a whole bathroom renovation job, there will often be a need to fill gaps and seal around areas such as door frames and skirting. Here an acrylic product is recommended as they are suitable for use on a wide array of materials including plastered walls, masonry and wood. While acrylics cannot be used where there will be contact with water, they are overpaintable, allowing a seamless high-quality finish.

Although many acrylic products are often considered unsuited to areas that experience significant movement, there are options on the market, such as Painters

Mate Flexible Filler, that have a degree of elasticity to resist cracking.

For fixes and repairs

For some jobs it will be a leaking bath or shower that needs to be addressed or a renewal of existing fittings rather than a full replacement. For these tasks it is useful to have a MS polymer product to hand as they are great all-rounders. They provide the flexibility and durability of silicone as well as the paintability of acrylics and can also be applied to wet or dry surfaces. This

makes MS polymers ideal for replacing old sealant in bathrooms as there is no need to thoroughly dry the area before application.

MS Polymers are also non-staining on porous materials, so they provide another option for sealing when working with certain types of stone. MS polymer products can also be used as an adhesive on a wide range of materials meaning it is a highly versatile option.

Choosing a quality solution

It can often be difficult to determine the quality of the product without using it. That is why it is important to select products from a trusted manufacturer that offers a range of solutions, formulated for different applications. Leading brands such as Geocel invest heavily in research and development, as well as product testing, to ensure trade professionals benefit from high-performance sealants and adhesives.

Where there is a need to seal around an area that includes porous surface materials, such as stone, marble or granite, a neutral silicone sealant should be used.

step-by-step WET ROOM

Kudos Showers explains how its Aqua4Ma wet room system can help to speed-up installation while providing a waterproof solution.

Kudos runs through a step-by-step installation for its Evolution featuring a centre waste onto floorboards

First, make sure you have the correct tools. To complete an Evolution installation you will need:

● Solvent weld

● Spirit level

● Circular saw

● Hand saw

● Drill with screw bit

● Stanley knife

● 152OD hole cutter

● Tape measure, pencil

● Drill bit

● Notched trowel

Important things to check before getting started:

● Check the existing floor needs to be level, however, a tolerance of 5mm per metre is acceptable and tiles need to be bedded-up to compensate for this.

● Allowance must be made by the installer when tiling to compensate for any difference in levels created by the trimming of the shower base.

● Recommended dry wall screws only (diameter 3.8/4.2mm thread) are used to fix the base and panels to the floor and walls. Screw lengths will be dependent upon the panel/floorboard thicknesses used.

1 I Fit the skirting to the stud wall using standard dry wall screws. It is the same process should you wish to fit Aqua4Ma 15mm tongue and grooved panels to extend the shower area further. Ensure that you apply a bead of solvent weld to every join within the skirting or wall panels.

2 I Dry fit the deck. This process is the same for both aqua4ma linear and evolution decks

a. Place the deck in the desired position

b. Mark the position of the waste hole

c. Trim the tray (if required and ensure that you only trim sides that meet the wall)

d. Check the waste positioning in relation to the joists/ pipework

4 I Connect the waste body using 1.5”/ 40mm UK compression waste pipe (not supplied), ensuring that the waste body is positioned to the centre of the cut-out.

We recommend that the shower waste is connected to its own dedicated pipework and should not be shared with other waste pipes.

5 I Place the tray into position and then fit the threaded connector, wedge seal, grill retainer and height spacers (as required). Twist the threaded connector into the waste using the tool provided.

For ease, we have used a pre-cut piece of Aqua4ma (wood or similar would also work) that is 150mm wide and measures roughly the same length as the deck that we are installing. The pre-marked border on the deck gives you a clear starting point which is 20mm in from the edge of the deck and flooring. Using the pre-cut material, we then mark out our squares. Once all screws have been fitted, go over all joint and skirting lines with remaining solvent weld.

7 I Should you wish to extend the wetroom flooring beyond the tray/ deck you will need to ensure that the flooring is installed to the same height as the deck. To do this you can use either 18mm ply plus 7mm Aqua4ma floor panels or the 25mm Aqua4ma floor panels.

6 I Next, secure the tray using drywall screws around the outside of the square groove so that you miss the square steel support plate (when installing onto a solid floor please apply flexible tile adhesive to the underside of the tray)

Remove the tray, and (in the centre of the marked position) drill a hole with a 152mmOD hole saw; to install the tray on to a solid floor you will need to remove the section of concrete/ screed for the waste body and waste pipe.

**When installing a linear deck, rather than cutting a circular hole you will need to cut out a rectangular hole to fit the plate.

Mark out 150mm squares on to the tray to help with the even placement of screws.

Start by laying down the 18mm ply-boards and then secure them in place using dry-wall screws at 150mm centres. Using Kudos solvent weld, apply a continuous bead to the edge of the shower base. Then apply a cement based flexible tile adhesive (not ready mixed) to the 7mm aqua4ma panels ensuring that you keep the adhesive approximately 50mm away from the edges.

Lay the 7mm panels up to the edge of the base applying pressure to ensure that the panels are fitted firmly against the base edge, then secure the panels in place using dry wall screws at 150mm centres and wipe away any surplus solvent weld.

Continue to fit panels to adjoining panels, using solvent weld on joints and screws to fix them to the floor (at 150mm centres as previously) until you have covered the desired area. All panels can be trimmed to size using either a handsaw, circular or jigsaw.

PHPI discovers a quick and neat way to hide pipework around radiators and towel rails.

Snappit rigid pipe finishing products could help. The product enables installers to quickly conceal unsightly pipework, achieving a neat and professional finish without compromising on quality. To install the product, cut the 15mm

Snappit pipe cover to size and snap it on. Then, to add to the finish, use the pipe collar supplied to create a seamless join from wall to floor. It is a mess-free alternative to painting and Snappit does not chip, flake or discolour.

For more information on Talon and its wide range of pipe clips and plumbing accessories please www.rdr.link/paw009

“Snappit is a really easy upsell for installers, as homeowners want that professional finish around their kitchen and bathrooms,” explained Dean Heathfield, Commercial Director of Talon. “We supply Snappit in kit form for radiator tails and towel rails, and in multiple colours, lengths and widths so they can be cut to size, giving you a perfect finish.”

Talon says Snappit is made from quality grade uPVC and help to shield pipes from potential damage, potentially reducing the risk of leaks and extending their lifespan.

The kits come in a variety of different colours to suit most homes and include white, chrome effect, anthracite grey and black in the Radiator and Towel Rail kits, while the Radiator Tail kit also features a rose gold option.

The Radiator and Radiator Tail kits come with a 15mm Snappit pipe sleeve in 2 x 200mm lengths and 2 x 18mm pipe collars while the Towel Rail Kit still features the 15mm Snappit pipe sleeve but in longer 500mm lengths, again with 2 x 18mm pipe collars

Snappit is a really easy upsell for installers, as homeowners want that professional finish around their kitchen and bathrooms

PipeSnug

As you may have seen on the PHPI website, Talon recently added PipeSnug and FlueSnug to its stable of products. Easy to install internally or externally, these products do away with the need for sealants, mortar, or expensive air sealing tape and are an easy way to comply with Part L of the Building Regulations which specify the need for pipe collars and grommets.

Just like the Snappit range, they also create a neat, professional finish and eliminate the need for pointing. Many gas engineers now use FlueSnug internally and externally to finish their installations and the product is endorsed by the major boiler manufacturers. The products are flexible enough to be pushed through a core-drilled hole from the inside, and yet rigid enough to snap back into place, and so eliminate the need for ladders or expensive scaffolding.

Low carbon

REFURBISHMENT

Buccleuch Estates manages a large portfolio of properties including Old Kirkhope in the Scottish Borders. As a business, protecting the local environment for each of their properties has always been a core priority for Buccleuch but with new legislation on the horizon, they are more aware than ever of the need to reduce the carbon footprint of the properties they look after.

When one of its properties needed refurbishing; a low carbon heating system was required to fulfil the property’s requirements while also adhering to the sustainable ethos of Buccleuch.

“We have a longstanding commitment to the environment here at Buccleuch,” said Callum Ramsay, Head of Architecture at Buccleuch. “Two of the mansion houses are already using renewable energy in the form of a ground source heat pump and biomass boiler and our estate offices at Bowhill and Langholm are also heated using biomass.

“We are also acutely aware that from 2025, there will be a requirement for our rental properties to achieve a minimum EPC rating of C at change of tenancy and for all remaining rental properties to achieve an EPC rating of C by 2028. The Scottish Government has also proposed that no new oil boilers should be installed in any new build properties from 2025, and no new gas boilers from 2030. Due to their rural location and age, the majority of Buccleuch’s Scottish residential properties are not on the gas grid and are currently heated using oil boilers.”

PHPI heads to the Scottish Borders to look at a heat pump installation in the grounds of Old Kirkhope.

The property is of traditional construction with stone walls and a slate roof.

refurbishment decisions. For Old Kirkhope, Grant UK’s in-house Design and Specification Department supported the Buccleuch Team by carrying out a heat loss calculation for the property and then specified the Aerona³ 10kW heat pump model.

“The heat pump is located on the south west elevation of the property, taking up minimal external space. This is adjacent to the utility room so that any noise from the heat pump is not heard within occupied rooms within the dwelling. When the heat pump is operating, however, the noise from the heat pump is minimal,” continued Joanna.

Traditional construction

“Old Kirkhope is fairly typical of Buccleuch’s rental properties,” explained Joanna Laidlaw, Architectural Technologist at Buccleuch. “It is a two-storey dwelling built approximately in the early 1800s, with a total floor area of 130 sqm. The property is of traditional construction with stone walls and a slate roof. The decision was made, when the property became vacant, that Old Kirkhope would benefit from a full refurbishment, to improve the layout for modern living and ensure EPC compliance for the future.

“The property was stripped to the bare walls to enable full insulation of the walls, floor and roof to meet current U-Value standards. With the full insulation complete, meeting current standards and reducing heat loss, Old Kirkhope was then deemed suitable for the installation and effective operation of an air source heat pump.”

Buccleuch’s architecture team asked Grant UK for a CPD session on air source heat pumps, to inform future designs and

Limited space

There was limited cupboard space available to locate the standard heat pump cylinder and plant, so it was decided that the QR Integrated cylinder would be the best solution. This is located within the utility room without taking up too much space.

Throughout the property, 12 Afinia radiators of various sizes were installed as, in this instance, underfloor heating was not a cost-effective solution. There was, however, a requirement for a heat emitter that would work as efficiently with the heat pump as possible.

“When we initially approached Grant UK about air source heat pump systems, Mike Pryde, Grant UK’s Regional Sales Manager for our area, arranged a CPD for various Buccleuch colleagues, outlining the Grant products available and how they work,” Joanna explained.

“Buccleuch and Grant remained engaged after the CPD, with Grant UK responding to our follow up queries.

“Once the system had been installed, a Grant engineer visited the property to carry out an assisted set up of the system, with the heating engineer and electrician, and a system demonstration with Buccleuch’s tenant (the end user).

The engineer was also on hand to answer any questions from the tenant and Buccleuch’s lettings team.

“Following the success at Old Kirkhope, Buccleuch now have various ongoing projects where Grant UK have provided technical support, including heat pump and radiator specification. Throughout this project and our other current projects, the level of customer service and technical support Buccleuch have received from Grant has been excellent,” concluded Joanna.

PRIORITYDOMESTIC HOT WATER

Condensing system boilers are energy efficient, however you can increase this efficiency further using Priority Domestic Hot Water (PDHW) also known as X-Plan. It’s a simple way of setting up your compliant boiler to provide two distinct flow temperatures, one for space heating, the other for water heating, without one impacting on the other.

And the beauty of X-Plan is that there’s less wiring complexity compared to S- and Y-Plan, but that’s not the best thing: Traditional S- and Y-Plan systems do not allow condensing boilers to 'condense' when the hot water cylinder is being reheated because the return water temperature will be above the dew point of the flue gases, which means, since condensing boilers became mandatory in 2005, gas continues to be wasted unnecessarily.

Full load

With X-Plan, during a hot water demand from the cylinder NTC sensor, for example, the boiler would ramp up to full load, as set up in the parameters, to match the cylinder coil input size and the pre-set target temperature of, say, 70⁰C. This heats the water in the fastest possible time; in fact, the recovery is so rapid that a 175-litre unvented cylinder with a 30kW-rated coil* can recover the cylinder (from 10˚-60˚C) in around 12 minutes. With recovery that fast, you can choose a smaller cylinder, saving space as well as energy. Like a combi boiler, the heating is not operational during hot water demand to

help facilitate the rapid recovery of the cylinder. For maximum efficiency, the space heating should be controlled through an OpenTherm-compliant device and, when the boiler switches from water heating to space heating, no excess heat can enter the space heating and room temperatures can’t overshoot.

Also key to the X-Plan benefits is the fact that the heating target temperature set on the boiler controls is completely independent to that of the hot water so, for instance, you can set the heating to 55˚C and the hot

water to 70˚C. Standard TPI controls can also be used via the 230V switching facility incorporated within the PCB.

Upgrade the system

If you’re replacing the boiler and the system is being upgraded from S- to X-Plan, the heating zone must incorporate a 22mm ‘normally open’ type valve. Using X-Plan you can upgrade any PDHW-compliant boiler as well as every boiler within the Intergas range. Customers benefit from the immediate convenience of superfast hot water combined with the option of low temperature heating (subject to heat loss calculations and correctly sized heat emitters) which inevitably enhances efficiency. Condensing boilers were introduced in the UK in 2005 to help improve energy efficiency by reducing gas consumption, but 18 years on many boilers don’t always achieve condensing mode for long periods due to poorly designed or commissioned heating systems. X-Plan enables households to reduce their gas consumption and impact on the environment continually.

*Cylinder capacity and coil input rating should be designed to suit the system and customer’s requirements; the 175/30 used in the Intergas training room in Kidderminster should not be used as the normal or standard option.

John Lawton, Technical Product Manager, Intergas Heating Solutions, takes look at the benefits of using X-Plan.

STAY CONNECTED

Following two successful product launches at the London Science Museum, and InstallerShow, Vaillant has unveiled the next generation of its well-known ecoTEC plus boiler and a brand new myVAILLANT connect gateway. Responding to installer feedback, Vaillant has remastered its ecoTEC plus combination and system range incorporating a range of refinements, designed to improve both installer and end user experience whilst keeping the features and layout engineers are familiar with. The new models work with natural gas today, as well as being hydrogen-prepared for the future. The company says most models are also LPG convertible without the need for a conversion kit.

The remastered ecoTEC plus combination and system range is joined by a new myVAILLANT connect gateway.

Familiar but improved

The launch brings a refined layout for the ecoTEC plus model, with components easily accessible from the front of the boiler to make routine maintenance and servicing straightforward.

Maintaining the same footprint, connections, pipe layouts and accessories as previous models, the company says installers will find many similarities between installing the existing and new models.

The new ecoTEC plus design retains the ‘Vaillant curve’; and has a modern design to fit into the style of many homes.

Enhanced performance

Incorporating ionisation technology, IoniDetect, Vaillant says the ecoTEC plus models unlocks the most efficient combustion and optimised performance, with the technology constantly monitoring the quality of the gas and maximising the available energy. Incorporating LinBUS technology the system collects performance data on key components, enabling installers to remotely access and diagnose any issues, as well as providing increased detailed information transferal between system components.

With the new Limp Home function, if the ecoTEC plus detects a fault, it will try and correct itself 10 times. If it can’t correct itself, it will run at a reduced output and alert the homeowner and the installer.

Smart home integration

To complement the ecoTEC plus, Vaillant has also launched myVAILLANT connect, a new gateway to provide a connected heating system solution, designed to enable easier and more intuitive smart home integration.

The new gateway integrates with numerous smart-home platforms, including Apple HomeKit, Amazon Alexa and coming soon, Google Home. Supporting homeowners with the ability to access and activate their heating system remotely and conveniently via smart mobile devices, as well as offering proactive remote diagnostics and energy management solutions thanks to the new myVAILLANT Smart Home Subscriptions.

For installers, the installation of the new gateway is straightforward with the new ecoTEC plus, with a simple one-cable plug and play solution and weather compensation out of the box possible.

Mark Wilkins, Technologies and Training Director at Vaillant said: “We are excited to be able to showcase the latest version of the ecoTEC plus. Working closely with our installers and end users, we set out to update our existing product without losing the familiarity that has made it so popular over the last decade. The result is the new ecoTEC plus, the same boiler installers know and love, remastered to suit the performance, efficiency and connectivity demands for today and the future.

“As the use of smart technology in the home evolves, the role of connectivity to create enhanced comfort and efficiency via domestic heating appliances has grown. In response to this, we’ve worked hard to ensure the new ecoTEC plus, together with myVAILLANT connect, puts increased control at homeowners’ fingertips.”

ALPHA’S HYDRO HEAT PUMP

Featuring a built-in weather compensation probe, the new Hydro Heat Pump from Alpha also features App-based remote control.

The Alpha Hydro is a single-phase solution which pairs with a pre-plumbed 200 litre cylinder and Smartech controls to provide an efficient heating system. The heat pump is a low-temperature system best suited to continuous operation – in contrast with a gas boiler which switches on and off during the day to keep the house at a required level.

One main feature of the Hydro is its built-in weather compensation probe. This is designed to ensure precise monitoring of inside and outside temperatures. By ensuring timely changes in the heat delivered, the weather compensation will help to keep the desired levels of heat in the property constant without the homeowner noticing any fluctuations.

Smartech Controls

The Hydro is managed using the Alpha Smartech controller, enabling smart app based remote control. These enable users to programme their heating systems to suit their lifestyle and desired comfort level from anywhere, thanks to a wireless thermostat which links to Wi-Fi via a mobile device. These are compatible with the Alpha Smartech app available on iOS and Android.

Control Panel

In addition, and to save installation time and space, the pre-plumbed 200-cylinder assembly comes fitted with a fully wired control panel. The only requirements are connections to the outside heat pump using a two-core cable and a 13A power supply. The Smartech thermostat is then wirelessly connected for temperature and time user settings with the Wi-Fi user app option. An optional further heating zone can be served directly from the cylinder with the second zone kit valve and Smartech expansion kit.

Daniel Wilden, Renewable Product Manager for Alpha, commented: “The Alpha Hydro offers those who are ready to embrace energy efficient technology the perfect solution to do so. With the Hydro heat pump able to operate at a lower temperature for longer, homeowners need no longer worry about turning their heating on and off to keep their homes at a desired level. The brains of the system will work to be as efficient as possible, always keeping the home at an ideal and even temperature. It is vital for installers to understand the requirements of this system as they will be obliged to ensure that it is set up correctly for optimum performance. Our training is available to assist installers in doing this.”

Specialist Training

Offering dedicated training, Alpha is helping to support installers with the transition to renewable heating systems. Now available at various locations nationwide, the company’s in-house specialists provide practical advice on system designs, key features and considerations when fitting a heat pump; together with expert, hands-on training in product positioning and installation.

Alpha encourages installers to attend its free training centres in order to improve product knowledge and skills and stay up to date with the latest innovations and gain practical hands-on experience. Those who take up the training also have the opportunity to discuss the latest energy saving products and relevant legislation.

FLOOR IT

PHPI recently paid a visit to OMNIE’s headquarters to discover more about the UFH solutions from the Exeter-based company.

The concept of supplying a routed structural floor panel that will accommodate UFH pipes has been pioneered by OMNIE for many years. The result is a two-in-one product that has strong performance and installer friendly features –and, with the introduction of OMNIE’s TorFloor 2, it’s an idea that has now been developed still further.

“Everything OMNIE does in terms of its product design is about transfer of heat,” explained CEO Darren Trivett. “An efficient transfer from the pipe into the panel at reasonable water temperatures provides the higher heat outputs that older buildings in particular demand. When you consider that the UK has the oldest housing stock in Europe, a product that can deal with higher levels of heat loss is essential, especially as we transition to heat pumps.”

Product innovations

One key feature is the patented AL HEX aluminium diffuser technology integral to OMNIE's panel design –where soft temper aluminium is effectively wrapped around the pipes –efficiently defusing the heat laterally, minimising any clustering of higher temperatures around pipework. That means you can get more heat out of the flow without increasing the water temperature.

The OMNIE innovations go further, with a multi-directional pipe channel design facilitating easier installation. It removes the need for separate straight and loop end panels, or the hand routing of pipe channels. Those channels are spaced at 150mm centres whilst fluted pipe exits ensure a straightforward transition into the neighbouring panels.

All in one

Designed for suspended and batten floors, TorFloor 2 is also a floor deck and underfloor heating system in one. The 22mm chipboard lower panel is complemented by a 6mm wood fibre interlocking upper panel which is also routed, foiled and printed, fully encasing the pipe. The company says installers simply need to listen out for the click when the upper panel in positioned and they’ll know it is in place –with no glue required.

A printed panel on the floor face indicates the pipe pattern beneath and, with points for screws clearly marked, the installer has the reassurance of knowing the location of the pipe when securing to joists, designed to make for a much faster installation, and to help eliminates the costly mistake of putting a fixing through a pipe.

With TorFloor 2 aluminium is now in place both under and over the pipe, providing even more diffusing metal, and increasing heat outputs by 15% over the previous design –at a lower water temperature.

There’s also a choice of top panel

depending on the floor covering with woodfibre cement board and ply available –again, all routed, foiled and printed. The system produces 77W/m² at 50°C flow water temperature and is independently tested for structural strength (at 600mm joist centres) to the latest standards (tested to BS EN 1195).

TorFloor 2 is equally available as an acoustic panel, with 8mm rubber on the bottom of the cement board lower deck, whilst the base board can also be supplied as 22mm ply rather than chipboard. At the same time, all the different options on the base and top board are interchangeable and compatible.

Existing floors

While TorFloor 2 is a structural system, Lowboard 2 is intended for installation on an existing insulated floor. Exhibiting the same product enhancements — with an aluminium foiled base layer and top layer panel, and choice of woodfibre cement board and plywood — it is also an 18mm system. At roughly the height of a 5p piece, this makes it amongst the lowest profile

underfloor heating products on the market. OMNIE has also developed its Ultimate concept further with Ultimate 2 –an extruded polystyrene insulation panel. Said to save considerable time in comparison with its predecessor, with Ultimate 2 only the sub-floor surface needs to be primed. The panel itself is self-adhesive –simply peel off the back and position. Furthermore, the top of the panel is pre-primed at the factory, so it does not need to be done on site. Simply stick the panel down, install your pipework and add the levelling compound for a much quicker job all round.

PUMP IT UP

While the Spring budget left many divided, the additional funding from the Chancellor to help old, financially ailing swimming pools was a welcome boost. While part of the £63m budget is to help swimming pools with immediate financial difficulties, just under two-thirds of it (£40m) is devoted to decarbonising these buildings. Here, assessing the pumps that control building services around these facilities, and upgrading these pumps where necessary, is imperative. Installers will no doubt have a big part to play here, being at the coalface of influencing purchasing decisions and advising on pumps and their nuances.

Pool owners have a multitude of options available to achieve long-term efficiency,

but pump upgrades should arguably be at the top of the list as these products can be the source of unnecessarily high energy expenditure.

Ways to decarbonise

Swimming pool facilities are in many cases decades old. In extreme instances, some may have been developed before the 20th century. In consideration of the age of these buildings, most will be inefficient in relation to today’s new building standards. Concerningly, should these facilities still use old pumps, i.e., pumps with AC motors that work at fixed speeds and in silo to other building services, then they could be consistently wasting energy. Additionally, these pumps don’t offer any smart insights

to help swimming pool owners help drive energy efficiency going forward. Smart technology has been the protagonist to some of the biggest changes in the pump industry. The accessibility to smart technology was made possible with the breakthrough of electronically commutated (EC) motor technology. To demonstrate this, switching from a circulator pump with an AC motor to one with an EC motor can provide an immediate 30% reduction in energy use. The newer pumps also generally have variable speed drives on board too, meaning there is no need to install these components separately in what could be quite small spaces and plant rooms.

Hydraulic design

Delving deeper, for installers who are advising on swimming pool pump projects, it is important to identify pumps that have had a complete overhaul, as opposed to just a surface level equipping of EC motors. Many old pumps will be inefficient in terms of their hydraulic design, and although most manufacturers may already be fitting more efficient motors, they may still be using existing hydraulic components. Even though this does provide greater efficiency to the pump, the performance levels are incomparable to a pump that has

pumps can also be used to define an ongoing energy usage strategy with immediate energy savings through smart automation

undergone a redesign of its hydraulics. In metric terms, the MEI (Machine Efficiency Index) of an old, or altered pump will be very low, most likely between 0.0-0.4 on the scale. New pumps must be above 0.4, with Wilo’s latest offerings achieving 0.7. So, when EC motor technology, smart controls and an optimised hydraulic design come together, pumps can become much ‘smarter’ and efficient in operation. The result is that pumps can work at lower speeds while still performing their necessary function, meaning energy savings can be increased by as much as 60%.

Smart energy strategies

Instead of being seen simply as a vehicle of moving water around a building, pumps can also be used to define an ongoing energy usage strategy with immediate energy savings through smart automation, and installers are at the heart of this.

Performance data, alerts, warnings, and notifications can all ensure systems are well always maintained and operating to their highest efficiency, alongside the pumping requirements of the building. In swimming pools, where so much energy is used on secondary hot water systems and heating the facilities, this is invaluable. Data such as heat flow, cooling flow, volume flow is all available from modern pumps, all to help optimise a building’s energy needs.

This data may have previously been hidden with static (or sometimes now known as ‘dumb’) products and equipment. The combination of this data with other smart systems can provide insight into usage patterns. The result is better-regulated indoor climate control that keeps power consumption to a minimum.

INTEGRATEold AND NEW

Hamworthy Heating has introduced new plate heat exchangers to support the installation of its Stratton mk3 boiler in commercial premises.

To help support the installation of its new Stratton mk3 wall-hung condensing boiler onto existing heating systems, Hamworthy Heating has announced its latest range of Plate Heat Exchangers –designed to increase boiler protection and performance.

Energy-efficient boilers are now widely used, but there can be an issue when integrating a new condensing boiler into an existing system and pipework. Challenges to consider – pointed out by the company –are potential un-controlled leaks from existing systems causing raw oxygenated water to be constantly added to the system. This further adds to the corrosion of the system and boilers creating problems from blocking heat exchangers with suspended solids and corrosion problems from system metals.

To bridge the gap between old and new systems the company’s Stratton mk3 wall-hung condensing boiler is now available with a range of AHRI certified plate heat exchangers to protect the new boilers from old systems.

Compact solution

Featuring a brazed design with no need for gaskets or supporting equipment, the latest range of plate heat exchangers from Hamworthy Heating offer a compact solution to maximise plant room space and keep the boilers operating at maximum efficiency. The company says its latest plate heat exchangers feature a large

5:1

for clean operation with ErP Class 6 NOx emissions, and up to 97% gross seasonal efficiency. It is backed by a five-year heat exchanger warranty.

Available in seven different outputs from 40 to 150kW, the Stratton mk3can be cascaded to meet building demands or larger installations. In these applications, the company says plate heat exchangers can also be used as a pressure break, where heating, water service, or chilled water is being pumped up multiple storey heights, or in the case of older tank fed systems allows for the hydraulic separationof new to old.

ALTECNIC LAUNCHES CALEFFIXSMAGNETIC FILTER

Altecnic has released a new under boiler magnetic filter, the CALEFFI XS - a compact magnetic filter designed to protect heating and cooling systems from the harmful effects of impurities. With a filtration system that uses a mesh filter, a neodymium magnet, and a collection chamber, the new solution helps to remove impurities from systems. The mesh filter captures large particles, such as dirt and sand, while the magnet attracts and traps metal particles. The collection chamber captures the heaviest particles, such as rust and scale.

The company says that it can be installed underneath any type of boiler, and the transparent glass windows make it easy to see when the filter needs to be cleaned. The internal isolation valve has been designed so only water in the collection chamber is drained before cleaning the mesh.

Gary Perry, Managing Director at Altecnic, commented: “With homes being stretched for space, creating solutions that are compact whilst still being able to effectively protect the system is important.

“The CALEFFI XS provides a compact, versatile, and easy to install and maintain solution for installers and homeowners. It is the perfect choice for keeping domestic systems running smoothly and efficiently.”

VIESSMANN LAUNCHES LOWER OUTPUT ASHPS

Viessmann has added three new, lower output variants to its Vitocal 150-A/151-A domestic air source heat pump range. The 4, 6and 8kW models complement the existing 10, 13 and 16kW heat pumps launched in 2022, and have been developed to provide a wider choice of outputs and allowing heating modernisation projects suited to a broader range of properties.

All Vitocal 150-A/151-A models provide both heating and cooling and are available to purchase for connection to single-phase electricity supply, with three phase models also available for the 10 to 16kW variants. They use R290 natural propane refrigerant.

Both the wall-mounted Vitocal 150-A and the floor-standing Vitocal 151-A with integral 190-litre DHW cylinder, have a maximum flow temperature of 70°C. Both models also feature Viessmann’s Super Silent Design. For example, the 6kW outdoor unit has a sound pressure level of only 33.5dB(A) at a distance of three metres when installed against one wall in standard heating mode.

“Vitocal 150-A and 151-A heat pumps with natural propane refrigerant are highly efficient at the full range of flow temperatures and extremely quiet,” explained Darren McMahon, Viessmann Marketing Director.

“The arrival of the 4, 6 and 8kW models provides our installers with added flexibility to select the appropriately-sized product for homes with low heat losses, such as smaller or newer homes, or perhaps whole house retrofits. In the case of a whole house retrofit then the One Base control platform opens up the possibility for additional technologies to be integrated into the system such as PV, battery storage, MVHR and EV chargers.”

KNIPEX NEEDLE-NOSE COMBINATION PLIERS

A further development of the combination pliers range from the Knipex Wuppertal tool forge, is a combination plier with a new length of 185 millimetres. The company says these flexible pliers are twist-proof and feature a high lever transmission power joint designed to makes it easier to cut soft, medium-hard and hard wire. The convex profile of the serrations in the pipe gripping area results in a stable three-point contact and means round pipes can be easily gripped and powerfully turned. A milled transverse groove in the gripping area has been designed to make it easy to securely hold and pull-out items such as nails, pins and bolts.

ALTECNIC Dry Trap Tundish

Altecnic has launched a new Dry Trap Tundish. The new Tundish boasts a patented, anti-splash design with a transparent chamber that provides a visual indicator for discharge. It is fully compliant with G3 building regulations. Suited for installation with domestic central heating boilers, heat interface units (HIU), and hot water cylinders, the Altecnic Dry Trap Tundish has been designed for the hot water discharge from pressure and temperature relief valves to pass safely.

The Altecnic Dry Trap Tundish has a compact design and prevents the need to install both a tundish and a dry trap as the internal stainless-steel spring-loaded disc mechanism prevents odours from escaping. The stainless-steel spring exerts only a small force to close the valve, therefore only a small weight of water is required to open the valve. As such the greater the flow of water the more the valve will open, acting as a visual fault indicator.

VAILLANT

Heat Pump Challenge – Winner

Earlier this year, Vaillant called on homeowners and heating installers to share their heat pump projects in homes where the technology may, on the surface, not have seemed the most obvious option, with three lucky winners having their home featured in a video fronted by TV Presenter and Architecture Pundit, Kevin McCloud. Peacehaven homeowner and heating installer, Luke Sheppard, and his partner Isabel, were one of the winners. Luke said: “To be honest I entered the competition at the last minute and wasn’t expecting to win, so to receive the call saying we’d been selected as a winner, and that Kevin McCloud would be filming at our home, was incredible.”

The Vaillant aroTHERM plus heat pump at Luke’s 1960s three-bedroom semi-detached property replaced his existing gas boiler that was under three years old. Since its installation both Luke and Isabel have been impressed with how efficiently the property has been heated.
