Example

A quick way to sanity-check the result

With the example settings of 1,500 watts for 8 hours a day, the heater uses 12 kWh each day. Multiply that by your electricity price to estimate the actual cost.

Actual electricity use can vary with power settings, thermostat cycling, efficiency, standby use, and how the appliance is operated.
