What do I need? All you need is a heating mat, a control device, an R.C.D and the adhesive to stick the mat down to the subfloor.
What size heating mat? It is essential to make sure that the correct sized heating mat is ordered; remember, under floor heating is not installed under permanent furniture. The bathroom pictured is 1800mm long by 2500mm wide, this equals 4.5m2 of floor area, but the actual amount of under floor heating required is only 1.5m2. To calculate how much heating is required, add the lengths of all the runs i.e. 0.6 + 1.0 + 1.4 = 3.0 linear metres. Then, to calculate the m2, multiply the overall length by the width (in this case a UFHD Standard mat at 0.5m2 wide), 3.0m x 0.5m = 1.5m2. If the measurement is not equal to a mat size you should always select a system that is smaller, never larger than required.
When calculating a floor area check the width of the mat, some of our systems are 0.3m wide and some are 1.0m wide. What controls should I use? For most areas we recommend having a time control and thermostat combined unit. This timer/thermostat can be used to monitor the temperature at floor level. If the sytem is to be used for floor warming, you should have a floor thermostat, and for sole source heating an air and floor thermostat. Individual thermostats are available. What type of system?
