5 key points to safely using electric underfloor heating under carpeted floors
(1) Tog value of Carpet and Underlay
Carpet and underlay are both not great conductors of heat so the thinner they are the higher the output of the system and
the faster the warm up time. The maximum recommended combined tog of the carpet and underlay is 2.5. This information
can be found out by the carpet retailer or manufacturer.
(2) Type of carpet
Hessian, felt backed and seagrass carpets are generally compatible with electric underfloor heating as long as the tog values
don’t exceed the maximum limit.
(3) Maximum floor temperature
Carpet should never get above 27C. The room thermostats should have a floor probes which will automatically shut of the underfloor
heating if the floors get above this temperature. All of Rayotec’s thermostats have floor probes to protect the flooring.
(4) Earthed system
Make sure that the underfloor heating product you purchase is earthed for safety reasons even if it not installed in a wet room.
(5) Palziv Insulation: Easy to install
Always use a suitable insulation under the electric underfloor heating. Not only does it reduce warm up time and running
costs but it also protect the matting. Rayotec supply the advanced Palziv system that not only has fantastic insulation
properties but is also much easier and faster to install when compared to traditional foam boards
