Power supply; three wires of 2.5mm from main DB to the transformer location will be installed. This is done for each heating zone.

Each heating zone will have its own fuse. 

Two 1.5 mm wires from the transformer to the thermostat placed on the wall (this is not needed for a wireless thermostat).

A cement screed must be present on the floor as our heating tapes cannot be installed directly on a loose material (torba). 

A layer of thermal insulation is necessary to prevent heat loss.
