Under tile heating refers to underfloor heating systems that are installed between the floor and the tiles. Typical systems are either hydronic (water based) or electric. They work by heating the tile from within the cementing, between a wooden or concrete base and the tiles themselves.
Different types of under tile heating systems
There are a few different types of under tile heating kits available. The right one to choose is based upon a few different factors, including the size of your space, the amount of heat you want the system to provide, and whether you are installing the under tile heating system in an internal or external room.
The first type is a loose wire or cable kit, which comes as a roll of cable on a drum. You mark out your floor, and space the cable according to however you see fit. The second type is the cable mat system, which works exactly as the loose wire kit, except that the cables have been embedded into matting and spaced for you. Cable mats come in different watts per metres squared. For instance, 150 watts per m2 is a good choice for an internal room, while 200 watts per m2 is better for something like a conservatory.
The use of underfloor heating insulation
When installing an under tile heating system, it also is a good idea to use underfloor heating insulation in the form of tile backer insulation boards, which block the heat from penetrating into the wooden or concrete sub-floor.
