Abstract
A system for heating domestic hot water includes solar collectors for raising the temperature of the water in the usual hot water storage tank. When a tap is opened, the water is drawn out of the tank and directed through a mixing valve which checks the temperature of the water and, if necessary, adjusts the temperature to an intermediate temperature somewhat below the temperature at which the water is to be used. The water then passes through a heater in which the temperature of the water is quickly raised to the elevated temperature at which it is normally used in households.
