There are two options for safely heating carpeted floors, one is with a 12mm layer of levelling compound over a 160W/m² heating mat and the other option is our combymat system combined with overlay boards (see picture). 

Be aware that the carpet and underlay combined should have a combined Tog rating below 1.8. Most hessian-backed carpets when used with suitable underlay will have a Tog rating below this. 

Thermal underfloor insulation boards installed beneath the heating system will increase the heating up time and reduce running costs. Our combymat system must be used with our 6mm Decora insulation layer. 

If you have any questions or are considering another type of flooring please call our technical department to discuss options on 01444 247020 or contact us here.
