FAQs

A Rapid Response® floor heating system produces heat in as little as 30 minutes because it has a level of controllability not seen before in under floor heating. Combined with our Home Heating Controls it can be turned on, off, up, down in individual areas of the home at the touch of a button on your smart phone, Ipad or laptop from wherever

The Rapid Response® heating system is a water-based floor heating system that uses low-temperature warm water to heat rooms evenly and quickly. Input temperatures can be as low as 45°C, using half the energy required to heat a radiator at 70-90°C.

This combined with the on demand nature of The Rapid Response® heating system, allows users to only heat the rooms they’re using, and not have to leave the heating on all the time like old traditional screed systems which took days to heat and cool.

The responsive use and lower energy requirements to run the Rapid Response® heating system make it a low carbon solution that’s compatible with current heating technology like gas/oil boilers; as well as working efficiently with alternative fuels of the future like hydrogen boilers and air & ground source heat pumps.

Rapid Response® on demand heat can reach desired temperatures in as little as 30 minutes.

This is thanks to all the work done in developing the Rapid Response® aluminium that’s used in both the board and pipe.

No, the spray contains no carcinogens and is CFC free.

Not at all! Rapid Response® boards are retro-fitted to the existing floor using our Wunda adhesive spray.

This saves time & cost in the installation as well as avoids any potential risks in digging up decades-old concrete substrates.

Rapid Response® is available in 16mm & 20mm profile boards.

The Rapid Response® boards come in 3 densities of EPS (Expanded Polystyrene), our Premium+ range is our strongest and most insulative board.

We got it tested at the University of Salford by their UKAS accredited product testing lab and got the following results back:

20mm of Rapid Response® has an R-value of 0.447 (+/- 2%)

16mm of Rapid Response® an R-value of 0.379 (+/- 2.8%)

So in comparison to a system using just radiators, it’s superior in insulation and will heat more sufficiently with better energy efficiency.

Wunda only provides pipe which is 100% leak proof. By using a 5 layered pipe comprised of an EVOH barrier to prevent oxygen ingress and rusting the aluminium core as well as Pert for superior flexibility.

We also pressurise the pipe at the point of manufacture, so you know instantly before putting it in the floor whether the product’s been comprised in transit. In over 14 years of manufacturing and supplying floor heating, we’ve never had a leak. Ever.

At Wunda we know how important it is to get your order to you quickly. For areas in the UK mainland if you place your order before 6.00pm we can provide our standard delivery in the next 2 – 3 working days.

Joist systems are perfect for upper floor properties.

Ideally the manifold should be sited as centrally as possible. The manifold position will be marked on your pipe layout drawing. It can be hidden inside an existing cupboard or we can provide an elegant manifold cabinet.

A manifold allows water to pass through its hollow core, this water then is distributed to the relevant destination (loop/zone). It will generally incorporate a pump and mixing valve to circulate the water around the loops & regulate the water temperature to a point that is suited for the floor finish

We supply pipe layout drawings which detail where every loop of pipe is laid and the length of each loop. You or your installer can’t go wrong!

Water based floor heating is laid using continuous loops of pipe in the floor, meaning the only joins are at the manifold – not under the floor.

Pipe that is pressure sealed at the point of manufacture like Wunda’s emits a hissing escape of air when the seal is cut on site. This allows the installer to safely guarantee the pipe is 100% leak proof before install and will give you peace of mind too.

We recommend having regular servicing to maintain an efficient system, when you have the boiler serviced for example to check inhibitor levels are still ok, no air locks in the system causing poor performance. With regular preventative maintenance, you will have no problems of breakdown

Thanks to retro-fit systems like Rapid Response® 100m² can be laid in just two days using quick drying Wunda Spray adhesive. It’s no longer a case of digging all your floors up, simply take up your carpet, prepare your sub-floor and lay a retro-fit system. 

Retro-fit options like Rapid Response^® floor heating boards are laid directly under your floor finish and when covered with the optimum thickness of 200 micron aluminium they provide Rapid Response^® warmth reaching desired temperatures in 30 minutes and ensuring an even heat across the entire floor – this makes floor heating just as controllable as radiators.

Old fashioned floor heating laid deep in concrete could take up to 72 hours to heat up or cool down.

No! That’s the old fashioned way. Modern floor heating such as Rapid Response^® floor heating comes in moulded, easy to shape, high density polystyrene aluminium coated boards made from eco-friendly EPS (as opposed to harmful XPS). The board is bonded to the existing floor before running the pipes in and through to the manifold. The desired floor finish is laid on top – no digging, no mess!

Screed systems are traditionally used in new build projects. Screed systems require the floor heating pipes to be fixed to the sub floor insulation layer prior to being encased in a layer of concrete or chemical screed. The warm water in the pipes heat up the concrete (screed) which acts as a thermal store and radiates it into the living space. This process can take a few hours to both heat up and cool down and is less controllable than overfloor systems.

A hardwired thermostat is powered by a 240v mains supply, a physical wire (3 core plus earth) Is used to trigger the appropriate output, to a wiring centre if one of many thermostats, or directly to the output if a single zone.

A wireless thermostat communicates to a receiver using radio frequency (RF) (either single channel or multi zone depending on the number of thermostats you have) meaning no need for wiring between the thermostat and manifold. Our RF thermostats cannot take a floor limitation probe so other steps are required to protect temperature sensitive floor finishes.

Not at all! Wunda’s floor heating systems have been developed with the confident DIYer in mind, being able to lay the pipe and panels, leaving final commissioning to the professionals. If you’re extending or renovating, even simpler would be to make use of the builders already on-site and get them to install it for you.

Floor heating and radiators happily 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. Any competent plumber can easily do this work for you.

Electric has much higher running costs in comparison to water based systems making it suitable for smaller areas such as en suites but not for larger living areas and whole homes. For open plan kitchen and family areas, water based systems are more economic costing up to 65% less to run than electric.

Most floor finishes can be used with floor heating, Wunda developed Rapid Response®, high density boards to support heavier floor finishes such as marble and stone tiles. These boards are independently approved by leading tile adhesive manufacturers to be laid directly on top without the need for an intermediary layer that other, less dense, boards may require, this helps to reduce system cost, build up height and lower install time.

If you’re opting for a wood floor be sure to install a floor probe to protect the integrity of the wood from fluctuating temperatures and do check with your flooring supplier as some products such as Beech wood may not be compatible.

No, most users of floor heating install on the ground floor and combine the system with radiators upstairs – but you can install throughout the whole house if you wish.

Absolutely, water based floor heating runs at lower temperatures, normally 35°C – 55°C, which is about half of what radiators run at. Water based floor heating is future proof and can be run from any heat source including heat pumps.

Warm water is pumped from the heat source to the manifold. 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.

An underfloor heating system can be an ideal and cost-effective way of keeping your home warm. It can be easily installed yet does require a fair amount of preparation and time.

Even before installing an underfloor heating system, there are other ways to reduce heat loss in your home which can prove easy and budget-friendly.

Find out more about how to install underfloor heating. 

Many people have the perception that underfloor heating is incredibly difficult to install. Involving huge pipes with lots of digging, often leading to them thinking it will be a costly and stressful process. However, with a Wunda Rapid Response® system, this could not be further from the truth.

There’s no digging up floors and installation is easy and relatively hassle free. 75m2 could be laid over a weekend by competent DIYers ready for your professionals to hook up to your heat source.

Find out more on how underfloor heating works.

Retrofitting underfloor heating can be a relatively easy process without the need to dig up the floors throughout your house. Wunda’s easy to install system comes with so many benefits, it warms up just as quickly as radiators and runs at a lower flow temperature which uses much less energy.

UFH circulates warm water through the plastic pipes to effectively heat up the floor first and allow for a warm living area with a cool ceiling. The water’s temperature can be between 35 and 55°C which is regulated by a mixing valve at the manifold.

Find the Ideal Temperature for Underfloor Heating in your home

Tile and natural stone floors work perfectly with underfloor heating as they are natural conductors. One thing to remember with these floor finishes is the thicker they are, the longer your response time will be and the longer the floor finish itself will hold the heat and take to cool down.
