Combine mats as needed to fit open walkable space, avoiding areas covered by cabinets, vanities or other permanent fixtures. The heating mats cannot be shortened, so avoid over-filling. Each mat will connect to the thermostat, so larger mats will reduce required connections. On a sole thermostat, 120V mats cover up to 200 ft²; 240V mats cover up to 400 ft². DO NOT MIX VOLTAGES.

Thermostat

A floor heating thermostat is necessary to control your radiant heat system. Most of our floor heating thermostats are dual-voltage and include a 5ma GFCI, unlike models from online warehouse retailers. A thermostat is capable of a 15-Amp load; adding a power module or relay will increase system load capacity. Each includes a floor sensor, but a backup is recommended. Select 1 thermostat for each zone desired. Contact an expert for guidance.
