Underfloor Heating Solutions for Carpet

Warm carpets feel great underfoot, but they also help keep your home healthy by keeping humidity levels low, keeping dust mites and other allergens in check.

Under Carpet Heating

hybrid

Underfloor heating is a compatible heating system with carpet. Both electric and warm water systems are perfectly suitable floor heating solutions for use under a carpet floor covering.

There are several benefits to having under carpet heating. First of all hygiene. Carpets tend to absorb dust. Furthermore, the hot air from conventional radiators causes the air in the room to circulate. As a result of this,  they circulate the dust and impurities. Underfloor heating heats up objects rather than the air and does not cause air circulation. Radiant heat is, therefore, the most suitable heating system for carpets.

Electric Underfloor and Foil Heater Systems

The most commonly used floor heating solution with carpet is the Warmup Foil Heater. Foil Heater is specifically suitable for use with floating floors and large and regular shaped areas. The super-thin, fully earthed, flat aluminium foil will not raise the floor levels visibly, hence why it makes a great solution for renovations.

Tog Value of the Carpet with Underfloor Heating

Warmup has a wide range of systems from electric to wet underfloor heating to ensure the perfect heating solution for your carpet floors.

When choosing your carpet flooring, attention must be paid to the overall thickness of any materials above the heater including any underlays and overlays.

The underlay should have low thermal resistance and the carpet should be hessian backed to promote efficient operation of the system. A felt underlay should not be used as it may create a thermal blocker hindering the performance of the system.

Everything above the heater, including underlay, overlay, and final floor finish needs to be in the limits set in the table below. The typical carpet is 1.0 to 2 tog, but you should always check with the manufacturer the suitability for underfloor heating and ensure that the overall tog value (including any underlays or overlays) does not exceed the 2.5. It is not recommended to install underfloor heating with carpet if the limits below are not met. This may hinder the performance of the system and result in the system not working as desired.
