The table lists the standard components for each size. A floor sensor is supplied with the thermostat. The kit size is the combined area of the individual mats; select it according to the floor area actually being heated.
Fully embed the heating mats in suitable tile adhesive or levelling compound according to the installation instructions. Never cut or shorten the heating cable. Allow the adhesive or compound to cure fully before switching on.
Have a qualified electrician assess the total load, circuit allocation, protection and connection of thermostats and load modules. An additional load module does not increase the capacity of an existing circuit.
