Underfloor Heating for Carpet

Carpet and Rugs with Underfloor Heating 

Carpets and rugs can be used with underfloor heating. But it is important to remember that as they are usually insulators, there are some limitations to the type of carpet or rug you choose. A floor finish that is an insulator will resist the rising heat and could stop it from coming through the floor into your room. 

It’s always best to check with your supplier if their product is suitable for use with underfloor heating, but if you have any carpet related underfloor heating questions then feel free to get in touch. It is advised that 2.5 is the max combined tog rating of the carpet, underlay and any intermediate layers, for reference Persian rugs are often 1.9 tog. 

Installing Underfloor Heating with Carpet Flooring 

When installing Carpet flooring over the Wunda Rapid Response® system, two methods are recommended due to the thin nature of these floor finishes. Always consult your flooring supplier for specific guidance.

Method 1 (Recommended):
After pressure testing the system, lay Wunda Duo Board with a vapour barrier, then install the Carpet on top. This method is quicker and simpler.

Method 2:
After pressure testing, prime the boards with an approved primer and pour a 10mm layer of levelling compound. Once dry, install the flooring. This method is often required for wet rooms, bathrooms, and ensuites.

Approved levelling systems:

  • Ultra ProLevel Ultimate with Ultra Prime It Multi Surface Primer
  • Mapei Ultraplan Renovation Screed with Mapei Eco Prim Grip

Ensure all unused pipe channels have the aluminium cut away and are filled with compound. Levelling materials are not supplied by Wunda but are readily available.

Underfloor Heating Energy Efficiency

Radiator systems are the 20th century equivalent of a fireplace. They need your boiler or heat pump to supply  hot water temperatures (60-80 degrees) so that they can emit heat into the room.

Water based Underfloor heating works differently, it is like having a huge radiator spread out beneath your floor. Underfloor heating can cover the entire floor space allowing it to use much lower water temperatures (35-45 degrees) to transmit heat throughout the room, making it the go to energy efficient and sustainable system of choice.
