Estimate the electricity usage cost of electric underfloor heating using the total rated heater power, scheduled hours and your electricity usage rate.

Daily energy (kWh) = heater power (W) ÷ 1,000 × scheduled hours × heating duty cycle (%)/100. Daily cost = daily energy × electricity rate ($/kWh).

Actual consumption depends on warm-up time, insulation, floor construction, weather and temperature settings. Installation costs, daily supply charges, thermostat standby use and solar or battery offsets are excluded.
