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.

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.

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.
