Abstract
A method of operating a water heater, the method including determining a predicted variation of a hot water consumption rate variable over a future time period and calculating a total required operating time of the water heater over that time period. The method further includes determining multiple possible operating profiles of the water heater that provide the total required operating time, and calculating a minimum hot water reserve for each profile. One of the profiles is selected based at least partially on that profile providing a minimum hot water reserve that is not less than a predetermined desired reserve capacity and the water heater is operated over the time period using that profile. The selected profile may be the profile that is calculated to have the lowest operational cost.
