Does radiant floor heating need dedicated circuit?
If you’re installing radiant floor heat in an existing room, you’ll need a dedicated 15- to 20-amp GFCI-protected circuit to power the system, and an excuse to lay a new tile floor. If you’re remodeling, it’s a good time to satisfy both requirements.
Do heated floors need a GFCI?
GFCI protection is NOT required for floor heating cables in a bathroom. GFCI protection is NOT required for floor heating cables in a kitchen.
How many amps does radiant floor heat use?
An electric floor heating system for a small or medium size bathroom typically draws about 1 to 4 amps. In kitchens as well as large bathrooms, the amperage draw of your radiant system may get to 4-8 amps or more.
Can I use a 15 amp breaker for Ditra heat?
Multiple DITRA-HEAT-E-HK heating cables over 15 amps cannot be connected to a single DITRA-HEAT-E thermostat.
How do you reset a GFCI heated floor?
Solid red light – press the on/off button to reset the GFCI. If the red light on your unit is located at the TOP or on the RIGHT side of the thermostat and the red light does not turn off, this indicates that there is a ground fault in the heating system.

Are 240V heater more efficient than 120V?
240V is most common for electrical appliances which require more power, such as a dryer, electric stove, or hot tub. There is no difference in efficiency in our heaters between 120V and 240V (or any other voltage). The reason why 240V is advantageous for appliances and heaters in a home has to do with amperage.
How much power does a heated bathroom floor use?
A typical electric floor heating element produces 15 watts per square foot. When installed in a small 35 square foot bathroom running a total of 8 hours a day, the system would only use 4.2 kWh per day. That’s 128.1 kWh per month. The national average kWh rate is $0.12.
What wiring do I need for underfloor heating?
