Heating & Cooling Running Costs

Calculate running costs for electric heaters, heat pumps, air conditioners, and other heating or cooling appliances.

Quick answer

How to estimate costs in this category

Heating and cooling often dominate household electricity use. Resistance heaters, heat pumps, air conditioners, and hot tubs all move or create heat, but their duty cycles and efficiency differ sharply. Compare monthly kWh, not wattage alone.

Each calculator below opens with example wattage and usage you can replace with figures from your appliance label, energy label, or plug-in meter. Enter your own electricity price per kWh for the most useful result.

Estimate only. Actual consumption varies by model, setting, condition, temperature, duty cycle, and tariff. Use measured energy use when accuracy matters.
