Calculate the time required to heat a volume of water with a fixed amount of electrical power

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

Volume of fluid to heat in litres:

Starting temperature degrees C:

Target temperature (finishing) degrees C:

Heating power available kW:

Density of fluid to heat in kg/dm:

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

The time required is: hours

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