What will it cost to run?

A usage estimate

Use the calculator to explore a constant-power operating scenario. It is a calculation from your inputs, not a prediction of a utility bill or a claim about energy savings. Source: Far Out editorial

What to enter

Take the wattage from the exact model specification. Enter the hours at that power level. A thermostat that cycles the heater changes the actual time drawing power. Source: Far Out editorial

Where the rate comes from

The rate is the preliminary US average residential electricity price for August 2026, from the Energy Information Administration's Electric Power Monthly release of October 23, 2026. Source: EIA

Your own rate may be higher or lower. Your utility bill shows the price you pay per kilowatt hour, and you can use it with the formula above for a local estimate. Source: Far Out editorial

Keep the limits visible

The configured US average rate is a reference rather than your local tariff. The arithmetic excludes additional charges and does not model thermostat cycling. Source: Far Out editorial

Make the number smaller

Pick the lowest wattage that warms your spot, run the heater for less time, and lower the main heating while you use it. Our efficiency guide explains why those choices matter more than the heater type. Source: Far Out editorial
