Water based floor heating has evolved...

04

In the 1950’s an American property developer Joseph Eichler built huge housing estates in California using the first generation of plastic piped,warm water floor heating - acclaimed by all as a huge success.

In Germany water based floor heating development was quickly taken up and, originating from research by the British giant ‘Imperial Chemicals Industry’ , a new generation of plastic Pex and Pert pipes with oxygen barriers was developed. Floor heating proved to be a huge success and today 80% of new homes in Germany are built with floor heating.

In the cold Nordic climate, simple low profile retro fit overfloor heating panels were developed for existing homes creating huge demand when renovating, upgrading insulation, and replacing radiators with floor heating. For many years home owners have benefitted in the improved warmth, comfort and fuel savings of up to 30%.

Here in the UK we’ve been slow to adopt floor heating. The first water based systems imported from Germany were expensive and as a result pipe was used sparingly by most installers, being placed at the bottom of thick concrete slabs with very wide centres (350 - 500 mm apart).

This saving on expensive pipe ruined performance and it could take up to 2 days for the floor to heat up from cold and almost as long to cool down, plus, controlling the heat output with analogue thermostats proved difficult.

Thus high prices, bad design, poor performance and, in part, to justify sky high system and installation prices, floor heating was made to seem like rocket science and did nothing to encourage popular use.

The latest development in this story comes from China, 20 years ago the government of the day banned copper and decreed that all new buildings could only use plastic pipes for plumbing.

This encouraged some of the largest German and American pipe companies to open massive plants there introducing the latest mass production techniques along with the benefit of stringent Chinesegovernment imposed quality control.

Floor heating proved very popular and now China has an enormous state of the art thriving plastic pipe production, for their own and export use.

Wunda Floor Heating has come a long way since 2006The Wunda Floor Heating division was set up to supply mass producedtop quality systems that were an improvement on old style floor heating,had to really work, be simple, heat up quickly, save fuel and be veryaffordable. Since 2006 we’ve managed to reduce the cost of our floor heating by at least 50%.

We love reliable, top quality mass produced products, good design andlow prices and like most modern high tech companies our components,all supported by long guarantees, are sourced from the best manufacturers in the UK, Europe and the Far East.

Being partners in a huge bulk buying group enables us to buy at themost advantageous prices, making savings we pass on to our customers.Component assembly, design and testing are all carried out in the UK.

Better by designOur in house system designers are equipped with the latest technologyand are encouraged to strive for improvement in all fields of floor heating whether it be for new build or retrofit application.

We have proved that by using technologically advanced pipe, close pipecentres (100 - 200 mm), modern digital controls, state of the artfixings and efficiently designed systems that heat up quickly, betterperformance will be achieved from Wunda designed floor heatingcompared to radiators or old style floor heating systems.

Our green systems are future proofWith so many ways to heat water - Modern Gas, oil, lpg, wood, coal and

bio mass boilers make the perfect partners for floor heating as do lowtemperature air and ground source heat pumps, thermal stores, solar,geo thermal and combined heat and power units. In fact our ‘green’systems will work with any heat source available even those thathaven’t been invented: providing they produce water at 35 - 50 °C.

Water based vs ElectricIn our opinion the pros and cons simply comes down to cost. In 2013Electricity being up to 60% more expensive per kilowatt hour than Gasand 50% more expensive than oil, is in fact more expensive than anyother fuel and, we believe, only suitable for heating small areasmaking warm water floor heating the greenest and cheapest form ofheating.

The benefits of floor heating

Floor heating Vs Radiators

Floor Heating - Radiant HeatWarm water Floor heating produces a natural radiant heat relatively cheaply - the heat from low temperature warm water gently rises from the floor, resulting in warm floors, warm feet and cool ceilings, just the way it should be. Temperatures at floor level are much higher than those achieved by convection.

Wunda Floor Heating✔

Radiators - Convected HeatConvection heating: is the type produced by radiators, storage heaters, wood burners and open fires. Propelling very expensive heat upwards, resulting in the ceilings being the warmest part of the room. Floors are much cooler, draughty and uncomfortable. With energy prices at an all time high and set to increase year on year, why waste it?

Total Control

Health and the environmentImagine the luxury of being able to arrange your furniture any way you want, without being restricted by unsightly radiators.

Floor heating sits invisibly under your decorative floor finishes, allowing unrestricted placement of your furniture and decor, releasing up to 15% more usable space!

Because floor heating uses warm water (typically 35-450 C) to achieve a comfortable living environment compared to the hot water required by radiators (typically 75-800C), less energy is used to achieve a comfortable living environment - resulting in cheaper energy bills.

With our floor heating systems every room is controlled by its own thermostat, giving you total control of the temperature in each living space, for instance, you may prefer cooler temperatures in you bedroom and kitchen, but higher in the lounge and bathroom.

All our systems allow you to determine when the heating comes on and goes off and if you choose a programmable thermostat, you will have even greater control, allowing 6 on/off events over each 24hr period.

Homes using floor heating systems are less prone to draughts and air turbulence, therefore cutting down on dust and airborne allergens, which is a great benefit to people who suffer from asthma and other allergies, also, because the floor is warmer and drier, it becomes a hostile environment for dust mites, which discourages them from breeding.

Lower Co2 emissions are also a bonus with floor heating systems, because they use less energy than typical central heating systems.

How floor heating works -1

Working with your existing central heating system

Wunda systems will work efficiently using low temperature water from any available heat source be it gas, oil, biomass, wood boiler or a low temperature heat pump. Boilers will normally have a heating range of 350C - 800C whereas a heat pump is really only efficient at 350C - 400C - any higher and the fuel efficiency drops considerably, Wunda systems are designed to work with heat pumps.

Understanding the manifold

Warm water is pumped from the heat source to the manifold assembly. If the floor heating requires warm water, the thermostatic valve will open allowing heated water into the manifold.

From the manifold heated water is pumped around the floor heating pipes, returning to the manifold and then either released back to the boiler/heat source via the boiler return valve for re-heating or blended back into the floor loop via a one way valve.

When all rooms reach desired temperatures, the room thermostats will signal to the actuators and pump to shut down, this in turn stops heated water circulating through the floor.

Hot water enters manifold from boiler and is blended with cooler water in the system to the desired temperature required.

Cool water returns to the boiler for re-heating

Total temperature control with ‘setback’ thermostats.

To save you even more money, Wunda recommends setback thermostats

Detailed factsheets are available from our website - wundafloorheating.co.uk

What are setback thermostatsWunda advanced setback thermostats draw smaller demands on your heat source.

Setback thermostats are programmed to keep an area at a reduced preset temperature during periods of the day when unused. Allowing fast rapid response and the most economic way to heat.

Without this control, systems are allowed to cool beyond a point of quick recovery, causing heavy and costly demands on the heat source and longer response times.

Wireless touch screen thermostatWith all the features of our hard wired thermostats - 6 on/off events in any 24hr period this thermostat can be programmed to control individual temperature and times of heating in a room, when programmed for set back control, this thermostat offers maximum comfort levels. This thermostat is ideal for retrofitting with out the need to chase wires.

Wunda - Low profile overfloor panelsFixed directly on top of existing concrete or wooden floors, Wunda low profile overfloor panels can be used to completely replace radiators in every room in the house, including conservatories.

Wunda low profile overfloor panels are a renovators dream - designed for people who want the benefits of traditional floor heating, but don’t want the mess and disruption of digging up their existing floors.

Wunda low profile overfloor panels are so lightweight and easy to install, you could even fit them yourself! - you only need a tradesman to connect the system to your heat source. Each panel is made from high density floor grade polystyrene with pre-grooved channels to accept aluminium heat spreader plates and floor heating pipe.

Installing Wunda Overfloor panel system

No need to dig up existing floors!

Panels are easily cut to accommodate the shape of the floor, with a craft knife or fine toothed saw.

Lay panels on floor according to the optional pipe layout drawing and number them so the sequence can be repeated later. Lift the panels and cut those that need modifying.

Apply our specially formulated adhesive to the floor in sections one panel deep. After 30 mins panels can be laid on top.

Start by sticking down the panels along one side of the room (in sequence) and work across the area towards the opposite wall. Repeat until entire floor is covered.

Apply spreaders only to the areas where pipe runs are straight until the entire floor area is covered.

The aluminium spreaders come ready backed with sticky tape, simply peel of the tape backing and apply the spreader into the board.

The pipe is easily installed by two people. The first walks with the pipe roll and reels it out while the second person carefully walks the pipe into the channels.

Bend and shape the pipe by hand into the turns, if necessary use aluminium tape to hold pipe in place.

Floor heating solutions

Screed based Clip Track systemIdeal for new builds and extensions where the floor heating pipes are to be embedded in a layer of screed (concrete).

Clip Track is a 1m length of plastic extrusion with pre-spaced channels to hold pipe. It is quick and easy to fix onto the insulation layer which sits on the concrete sub floor. Floor heating pipe is then clipped into the track and held neatly in place before a final screed of concrete is applied to cover the pipe.

Floor heating pipes in screed are slower to transmit heat into your living space than overfloor systems, because the heat has to be transmitted through approx 70mm of screed, but have the advantage of holding onto that heat for much longer, allowing you to turn off your heating earlier.

Installing Clip Track system

Fix the Clip Track to the insulation board using staples simply pushed in by hand (3 staples per length of Clip Track)

Measure the pipe centres and roughly translate the plan onto the floor as shown on the optional pipe layout drawing.

Be careful not to kink the pipe with a sharp bend. It is not necessary to follow the design of bends exactly.

A minimum traditional concrete screed thickness of 65mm should be used for domestic and light commercial use.

The screed should be allowed to dry naturally. Once the screed has fully dried, heat from the underfloor heating system can be introduced slowly.

Spacing between sections of Clip Track should be 1.5 metres, more when there is a concentration of bends.

When laying pipe in the track slots, ensure it is placed in the same slot position in subsequent sections, so that pipe runs line up.

Screed based Pipe & Staple systemThe Pipe & Staple system is ideal for new builds and extensions, where the floor heating pipes are to be embedded in a layer of screed (concrete). It is also the simplest method for underfloor heating installations.

Pipe & Staple system relies on barbed plastic staples to fix the pipe at regular intervals (either by hand or by using an optional staple gun) to the insulation layer which sits on the concrete sub floor. The floor heating pipe is held neatly in place by the staples before a final screed of concrete is applied to cover the pipe.

Screed based underfloor heating has the advantage of holding onto the heat for much longer, the screed acts like a giant storage radiator, which allows you to turn off your heating earlier while floor remains warm.

Page 17: Wunda - Beginners Guide to Floor Heating

Installing Pipe & Staple system

Pipe is fixed to the insulation board using staples simply pushed in by hand.

Measure the pipe centres and roughly translate the plan onto the floor as shown on the optional pipework drawing.

Don’t worry if your pipe runs are not straight, it will not affect performance.

A minimum traditional concrete screed thickness of 65mm should be used for domestic and light commercial use.

The screed should be allowed to dry naturally. Once the screed has fully dried, heat from the underfloor heating system can be introduced slowly.

Staples should be spaced 300mm apart on straight sections and 150mm apart on pipe returns.

Alternatively an optional staple gun is available which will speed things up.

If possible work with two people when laying the pipe; one person rolls out the coil and the other person to push the staples into insulation.

Screed based Plastic Pipe Tray systemThe Plastic Pipe Tray system is ideal for new builds and extensions, where the floor heating pipes are to be embedded in a layer of screed (concrete).

The Plastic Pipe Tray system uses strong lightweight castelated pipe trays that are quick to lay and easily cut to size and shape, forming a rigid guide for laying pipe.

The trays are laid over insulation and edged with perimeter strip to maximise system performance.

Screed based underfloor heating has the advantage of holding onto the heat for much longer, the screed acts like a giant storage radiator, which allows you to turn off your heating earlier while floor remains warm.

Installing Plastic Pipe Tray system

The trays are laid flat on the insulation and up against the perimeter strip with the polythene skirt laying on top of the insulation and tray.

Work with two people when laying the pipe; one person walks along rolling out the pipe and the other person follows behind to push the pipe into the panel.

A 400mm length of pipe conduit should be fitted around pipe work where it passes through internal walls or doorways or whenever any pipe work passes through an expansion join.

A minimum traditional concrete screed thickness of 65mm should be used for domestic and light commercial use.

The screed should be allowed to dry naturally. Once the screed has fully dried, heat from the underfloor heating system can be introduced slowly.

The next tray overlaps the first tray by interlocking the castellated nodule over the tray below.

Measure the pipe centres and translate the plan onto the pipe trays as shown in the optional pipe layout drawing.

Be careful not to kink the pipe with a sharp bend. it is better to produce a ‘light bulb bend’ .

Aluminium Spreader Plate systemAluminium spreader plates are used for joisted floors and are easily fixed between joists at 400mm & 600mm centres, using nails, screws or staples.

Pipe is laid into the pre-formed channels at 200mm pipe centres. Insulation below the spreader plates will ensure maximum performance from this system.

Installing Aluminium Spreader Plate system

Notch joists according to building regulations, if permissible or secure battens to the top of joist to allow pipe to pass between the joists allowing for bends and returns.

Allow a 15mm expansion gap between each plate. A good tip is to press a short length of pipe into the pipe channel to help line up the plates before fixing in place.

15mm masonry nail pipe clips can be used to secure pipes in notch

Having followed the pipe layout, you will reach the point of having to return the pipe to the manifold. Create your final bend and run the pipe back to the manifold using the notches/gap in batten.

Before re-laying your floor boards It is good practise to install a thin polythene sheeting over the spreader plates. This will help cut down any potential expansion noise as spreader plates warm up and cool down.

Ensure adequate insulation is fitted between joists. We advise a 50mm solid board or 150mm mineral wool.

Wearing safety gloves due to sharp edges lift the first spreader plate into place measuring 250mm from the wall.

Fix the spreader plate along the top of the joists using staples, nails or screws ensuring they are flush fitting.

Foiltec system for joisted floorsDesigned for use in any width suspended joist or battened floors using Foiltec aluminium foil in conjunction with Wunda Pipe, transmits heat evenly across the chosen floor finish. The aluminium foil is fully certified and designed for floor heating purposes.

The heat produced is contained in the void below the floor finish which naturally rises and permeates through the floor providing comfortable heat controlled by the room thermostat.

Foiltec is more labour intensive than some of our other floor heating solutions, but can easily accommodate non-standard joist centres often found in older properties.

Notch joists according to building regulations if permissible or secure battens to the top of joist to allow pipe to pass between the joists allowing for bends and returns.

Attach strapping to the top of the joists using nails/staples at 50cm intervals.

Attach pipe to strapping with cable ties. Use a tape measure to ensure pipes are spaced at the required centres.

Many flooring manufacturers i.e. solid wood/engineered board recommend the use of a damp proof membrane (DPM) if laying directly onto the joists. Please consult your flooring supplier.

Roll the Folitec out (shiny side up) ensuring foil is upstanding around edges of room by 75mm, trim where necessary ensuring no gaps are visible that could lose heat.

Staple Foiltec into place along the top and sides of the joists. Repeat this across the remaining joists. Cut to length with scissors when finished.

Lay the pipe into the Foiltec trough between joists following the optional pipe layout drawing. Return pipe through notches into the adjacent trough.

Pug Screed system for joisted floorsFor Underfloor Heating suitable for solid wooden joists only, that have been sized by a structural engineer to take the increased loadings. It is often chosen for use with low temperature heat sources such as Heat Pumps, as it acts as a thermal store and conducts heat more evenly to the surface above.

Pipe staples are fixed over the pipe into an insulation board and then embedded in a dry mix of sand and cement (Pug Screed). In order to support this system, batons are fixed to the sides of the joists. If the insulation is too thin to support the mix, plywood can be used to bridge the gap. A thin poly Membrane should be installed between the joists and the floor to stop any moisture affecting the surface above.

Installing Pug Screed system

Notch joists according to building regulations, if permissible or secure battens to the top of joist to allow pipe to pass between the joists allowing for bends and returns.

Following the optional pipe layout plan, fix the pipe to the insulation with pipe staples, alternatively an optional staple gun is available to speed up the process. Usually Joists are set at 400m centres, allowing 135-200mm centres for the pipe layout design.

When you have reached the point of having to return the pipe to the manifold. Create your return bend and run the pipe back to the manifold using the notches/gap in batten. Fix in place with 15mm pipe clips.

A minimum of 25mm thick dry screed is then laid, ensuring that it penetrates fully around the pipe and sits level with the top of the batten.

Once all spaces between the joists have been filled with the Pug Screed mix, floorboards can be re-laid. The pug mix will set hard naturally over time as it draws moisture from the air.

Please note: The Approximate weight loading for the pug mix when used as below, would be 20- 25kg m². Check with structural engineer or other qualified person if in doubt about weight loading.

Fix timber boards on battens between joists to support the system and insulation board.

High density Insulation board is fitted between joists, Allow a 25mm – 30mm gap between the top of the insulation board and the top of the joist for the Pug Screed mix.

A polythene membrane is then placed over the insulation & joists prior to fixing pipes and applying the pug screed mix.

Floor heating FAQ’s

Can I mix radiators and floor heating?Floor heating and radiators can work in conjunction with one another, to achieve this you will need to ‘T’ off from your boiler primaries, so one set of flow and return will go towards your radiators and the other to your floor heating system.

Where is the manifold located?Ideally the manifold should be sited as centrally as possible such as an understairs cupboard.

Can I run floor heating off my current boiler and pump?Floor heating can be run off any suitably sized boiler in conjunction with our pumped manifold set.

Where do the pipes in the floor go?We supply optional pipe layout drawings which detail where every loop of pipe is laid and the length of each loop.

Do I need to dig up my floors?Not with our retrofit Overfloor Panel system - there is no need to dig up your existing floors, simply lay the overfloor panels over your existing floors.

What if the pipe leaks?We only use continuous loops of pipe with no joins under the floor, the only connections are at the manifold flow and return.
