It might seem an unusual comment but some stones are colder than others. However, whichever stone you choose, you (and your feet!), will benefit from the installation of underfloor heating.
If you are having any type of new building constructed you may decide to install a water based underfloor heating, which would need to be provided by your building contractor. In nearly all other instances, electric underfloor heating can be fitted to most properties.
It is a common misconception that electric underfloor heating is expensive to run. In reality, if the room is well insulated and the heating is kept on constantly to a moderate temperature the cost will be approximately £3-£4 per square metre per annum!
This is because the costly element to underfloor heating is the initial heating up of the stone. Once the required temperature is attained, the cost to maintain that is minimal. This is the reason that the heating should be left on constantly and not turned on/off as one would with central heating systems.Learn more here
