What Is Rapid Response® Underfloor Heating?

Wunda’s Rapid Response® underfloor heating system uses  pipes fixed in Rapid Response® panels that sit between the structural base and floor finish.

The system is easy to install and easy to control.  Providing all the benefits of water underfloor heating. Low running costs, maximum comfort.

Wunda’s Rapid Response® system quickly heats a room (up to 40 minutes) using the lowest water temperatures 30-45°C. Ideal for new homes, renovations and home improvement projects.

Things to Consider about Rapid Response® Underfloor Heating

Build Up Height. The panels come in two sizes, 16mm and 20mm. In new build projects we recommend building this depth into your calculations. In retro-fit projects the consideration is ceiling height and adjusting your door heights.

Your Questions

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

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.
