Brief Installation Process

In 99% of situations, a 20-60mm sand cement screed needs to be laid over the electrical element so there is a medium between the heating element & the flooring.

It is extremely important to install the floor sensor in the heated area as the thermostat needs to be set to measure and regulate the floor temperature. The maximum heat as specified by the manufacturer is normally 27 degrees celsius. The thermostat will not regulate and adjust from the floor element itself to your specified programmed temperature if the floor sensor is not installed in the heated floor area. Please call us if this is not done, as we can help you switch the thermostat over to an air sensor instead.
