12. A method of controlling the heating of a water heater, said method including:
-
(a) measuring the cold water supply temperature for a water heater tank;
(b) identifying or calculating a thermostat cut out temperature using the measured cold water supply temperature and a desired output temperature;
(c) closing the circuit with a heating element to heat water in said tank until the thermostat detects a temperature substantially the same as said temperature identified or calculated in step (b), whereupon said thermostat opens the circuit with the heating element. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 36, 37, 38, 39)
