    Hi guys, had to create a new accounts so have been here while, but have a query on underfloor heating.

    Have been in our house a year or so and are having a bathroom refitted. Have exposed the underfloor heating, which I knew was there, and confirmed it is electric but we have not found any control panel. It is coming on, albeit at a low temperature (the elements are exposed the moment until a new floor is laid), but I have never located any controls. Could it be linked to the light switch, i.e. come on when the lights are on, (seems unlikely) or could it be always on?

    I am assuming any control panel would be either in the room, or nearby. Suspect it was installed within the last 10 years, so not sure it would be wireless.

    Thanks in advance!

    Find the power cables to the elements, trace them back to the supply, the controller will be there somewhere

    As well as connections to the elements there should be a temperature probs in the floor. That should go to some sort of control device. B

    There are two types of under floor heating, there is the type with a resistance cable which gives out a fixed amount of heat per meter, and needs a sensor to stop floor over heating, and there is the type using a chemical think main firm called Raychem and the chemical increases resistance as it warms up so is self regulating so does not really need the sensors.

    When sensors are used they go in pockets, so in theory at least they can be renewed without lifting the floor, and the cable for sensor not that long (typical 3 meters) so the thermostat has to be close to the sensor. So if the heating elements are exposed you should see the pocket for the sensor unless the Raychem version.
