An energy saving system and method for heating water are provided. The method for controlling the costs of heating water includes the steps of: using heat pumps to heat water in a heating tank during periods of low rate electricity to a pre-determined maximum temperature; maintaining the temperature of the water in the heating tank between a pre-determined minimum temperature and the pre-determined maximum temperature; transferring the heated water to a storage tank; maintaining the temperature of the water in the storage tank within a pre-determined temperature range; and supplying the heated water under pressure to consumers, the heated water having a temperature within the pre-determined temperature range.
