Underfloor Heating and Stone Floors

A stone floor is a conductor of heat. The temperature of a stone floor will be the same as the air temperature in a room. Therefore if your room is naturally warm and underfloor heating system may be something that is simply not necessary.

There are two underfloor systems in common use in the UK. Underfloor heating can be water-based or electric. A water-based system is generally pipes sitting in the subfloor. It is therefore common in new build houses as it adds 60mm to the floor height. Electric underfloor heating systems are a matt and generally add 6 – 8mm to the floor height. Therefore they are more common as the additional floor build-up is so small. Water-based underfloor heating is more expensive to install than electric but is also less expensive to run.

There are also two specifications of underfloor heating. A sole source heating system is designed to provide all the heat in a room and to remove the need for radiators. A backup system is designed to complement a central heating system. It is therefore less expensive but also less powerful.

As stone is a conductor of heat, it works very well with either underfloor heating system. However, it is important to note that if you have underfloor heating in your room you will need to use an anti-fracture membrane, flexible tile adhesive and flexible grout to cope with the extra subfloor movement it will create.
