There are many systems for under tile radiant heating It is a comfort that in the winter makes all the difference your bathroom. Some use water under the floor, this system is very efficient but costly to install.
The most common that we work with is the electric heat pad. The electrician sets up the system hardwired into he wall directly into the thermostat with a scream box wired in, A scream box is always required because it proves beyond a shadow of a doubt that the heat pad is still in working condition after the tile has been installed. The way it works is it is wired directly into the live system and very simply is constantly checking the circuit continuity and if the circuit is broken will emit a loud unmistakable ear piercing scream if the circuit is broken. This is a must for the installer as insurance and proof that after the tile is installed the heat pad is still in working order.
A warm tile floor is wonderful on the feet when stepping out of the shower. Also radiant heat keeps the bathroom toasty warm all the time. As the tile warms up the heat rises and keeps the room at a constant toasty temperature. Much like the fire bricks of a fireplace, the tile warms up, holds the heat and distributes it evenly throughout the room. It is very efficient and a big plus for any bathroom.
