This is an estimate calculator and may not be exact as many things can cause variances such as the exact amount of wattage your unit pulls, some states use 2 or 3 cost tiers, commercial vs. residential, peak times as well as the fact that your heater will be cycle on and off and your lamps unlikely will be on the entire time of the day.
Through test, our Solar Comfort was pulling 1440 watts and as low as 28 watts when just the fan was on. We also turn our thermostat down in the sleeping hours as well as when we will be gone from home for a long period of time.
For more accuracy in your own specific area, we advise that you find out the average cost per kilowatt-hour, which may be listed, on your bill or you can call your utility company for the cost as well. Then select the cost in the calculator.
