Electric Heating Electricity Cost Calculator

lectric heaters, whether they are fan heaters, halogen heaters, oil-filled radiators or convector heaters are rated inWatts (W)orKilowatts (kW). Find out what your heater is rated at, then use our energy calculator to see how much it will cost to run per hour, day or week.

*based on 6 hrs a day at maximum output using the Average rate of 18.54p/kWh (December 2019 tariff) for a unit of electricity. Heaters with a thermostat will automatically turn off when required room temperature is reached.

Can you get energy saving portable electric heaters?

Unfortunately not, all portable electric heaters will consume the same amount of electricity and produce the same amount of thermal heat, relative to power input. The only difference will be in how they deliver the heat, e.g. fan heaters are a good choice for quick heating of specific areas of a room, as you can direct the heat.

What will affect the running cost of the heater?

The power/energy rating (watts or kWh) will dictate the running cost per hour of any heater. The most effective way to reduce running costs is to keep the heat in, insulating and reducing draughts will help keep bills down. Low cost solutions, such as heavy curtains, blinds, draught excluders will all help. Loft and cavity wall insulation, double-glazing can dramatically reduce heating bills too.
