The hot water storage cylinder must be large enough to provide for a household’s peak hot water demand, but more water will be heated than needed if the cylinder is too large. The appropriate size depends primarily on the number of people in the household. 

Typical hot water usage is in the order of 40–60 litres per person per day.
