Calculate the electrical heating power required to heat a volume of water in a fixed time

By filling in the boxes in the water heating calculator below and clicking the “Calculate!” button, you can find the power in kW required to heat a volume of water. For the Theory & Explanation, click HERE.

Volume of fluid to heat in litres:

Starting temperature degrees C:

Target temperature (finishing) degrees C:

Heating time hours:

Density of fluid to heat in kg/dm:

Specific heat capacity of water kcal/kgx°C³: 1

The power required is: kW

If you now want to buy something to actually do some heating, you have options.
