Electric radiator electricity consumption calculator
Calculatete how much it costs to run an electric radiator per hour, day, month and year.
Calculatete now →How much does an electric radiator cost to run?
A resistive electric radiator usually has an easily identifiable power rating. Aun así, el coste real depende de cuántas horas esté funcionando y de si utiliza termostato para cortar el calentamiento.
La potencia nominal permite una estimación sencilla: vatios divididos entre 1000, multiplicados por las horas de uso y por el precio del kWh.
Use the calculator with example values →What do you need to calculate it?
Enter the appliance power, usage hours, days per month and your approximate price per kWh. If there is standby consumption, you can add it separately.
How to get a real-world figure
When possible, use an electricity consumption meter. This lets you replace the estimate with the measured consumption of your own appliance.
Basic formula
Consumption (kWh) = potencia (W) ÷ 1000 × horas de uso.
Cost = consumption (kWh) × electricity price.
