Underfloor Heating
Underfloor heating systems are growing in popularity and we are often asked about their compatibility with carpet. The Carpet Foundation carried out some research in conjunction with the Underfloor Heating Manufacturers Association (UHMA) and this proved conclusively that most carpet can be used over underfloor heating systems without impairing the performance of the system.
The research showed that a carpet/underlay with a combined thermal resistance of less than 2.5 togs allows the underfloor system to operate efficiently. Indeed, the real thermal resistance values of carpet/underlay were on average 1 tog lower than was previously believed.
The results showed that:
- none of the carpet/underlay combinations interfered with the efficient warming of the airspace in the room above
- The tested tog values of the carpets (using the test chamber as a life size ‘tog’ meter) were significantly lower than the previous laboratory test values
- Carpet and underlay with a combined ‘real’ thermal resistance of up to 2.5 tog (3.5 tog based on laboratory tests) may be used over underfloor heating systems.
So, while you can be reassured that carpet and underfloor heating systems can operate effectively and efficiently together we do recommend that you consult the heating manufacturer to ensure that your choice of carpet/underlay combination is suitable for the system.
