Do I need to install a GFCI breaker?2021-01-13T14:56:07-08:00

If you have radiant floor heating and an imbalance within the electrical currents occurs, the GFCI in the radiant heat thermostat will automatically and instantly disconnect the electrical lines from the radiant heating system. Gold Heat’s Sinope thermostats are GFCI protected and a GFCI breaker is not necessary.

Can I cut a heating element shorter or extend a heating element by splicing two together?2021-01-13T14:56:08-08:00

Unfortunately not.
The heating element inside each individual mat and cable is designed to produce a set amount of heat: 12–15 watts/sq ft or 41–51 BTUs (the measure of energy). Shortening the length of a heating element will cause it to produce more than the set amount of heat. Doing so can:

  • Decrease the life-span of the system
  • Void the warranty.
  • Cause the system to fail compliance (based on the North American electrical code)
Is it safe to install Gold Heat radiant floor heat in a shower?2021-01-13T14:56:08-08:00

Yes! Gold Heat electric radiant floor heat has been thoroughly tested and is UL and Canadian listed for use in shower floors. However, radiant floor heating is not approved to be installed in the walls of a shower and it is recommended that separate mats be used to heat the shower floor and the bathroom floor.

How much radiant heat do I need?2021-01-14T11:23:00-08:00

The number you’ll need to calculate is called “heated area.” This differs from the square footage of the room and also the area of flooring. To get this number, you have to subtract out areas that make no sense to heat, like behind a toilet.

The red area is the heating area.  Notice that the heating area does not include the area under the tub, under the sink, under the toilet, and cabinets.
