Our 3 top installation tips


Thermostat position

Start at the thermostat position. This means you won't have to extend the cold tail to reach the thermostat position.

BT21 Sensor-1

Floor sensor

Always install the floor temperature sensor in a conduit to facilitate replacement should it be required. If you don't want to use a conduit, install a second floor sensor as a spare.

Cable Protection

Don't cut the cable!

Don't cut the heating cable as it will void your warranty and result in poor performance and eventually cable failure!
