Hot Water Recovery Time Calculator

The above calculator is for calculating hot water recovery time for hot water cylinders. However it can be used to calculate general hot water recovery time for any amount of water. If you would like the ability to select higher KW amounts please either feel free to get in touch and tell us or use the formula to calculate it.

Volume is the amount of water you wish to heat up this is in litres.
Delta T is the change in temperature ie heating water from 10 °Celcius  to 50 °Celcius would be a Delta T of 40 °Celcius.
PowerKW is the power level of the heat source ie a 30 kw boiler would be 30 kw.
