Electrical Installation 

Do you need to use grounding nets with the Foil Heater?


No – the Foil Heaters are completely earthed, and can be installed without any additional grounding nets. The foil layer acts as a continuous earth and it is important that it is kept intact. See the foil installation manual for further information.

Can I use one thermostat to control multiple Foil Heaters ?


Yes, but all heaters being controlled by thermostat must be installed within the same room/zone. Each thermostat can control up to 16 amps of heating and maximum of two heaters can be wired directly into the back of the thermostat. If installing more than two heaters connect in parallel via a junction box.

Can more than one StickyMat Heater be controlled by the same thermostat?


Yes, but all heaters being controlled by thermostat must be installed within the same room/zone. Each thermostat can control up to 16 amps of heating. A maximum of two heaters can be wired directly into the back of the thermostat, when installing more than two heaters connections should be made via a junction box. If […]

Can I connect one Warmup heater to another in series?


Connecting one system to the other in series is often referred to as “daisy chaining”. Each floor heating system must be connected individually to the operating floor heating thermostat.

What are the electrical requirements for my Warmup system?


Please verify that the circuit can handle the amount of amperage your heating system requires. Your thermostat can only handle up to 15 amps so if you are connecting multiple heaters to one thermostat location, you may need to use a relay and a larger breaker. Your or your electrician can find out the amperage rating of your specific floor heating system in installation manual or printed on the box. Note: Just because the Warmup thermostats are dual voltage, this does not mean you can supply any voltage to your heating system. You must supply the voltage supplied to the voltage of your specific heater.
