Abstract
A hot water tempering system for use with a standard water heater storage tank includes a heat exchanger interposed between the hot water outlet means and the cold water inlet means for transferring heat from hot water exiting from the tank to cold water entering the tank. In this way the temperature of the hot water is tempered. The system is characterized by the fact that the cold water inlet means comprises a first conduit which passes through the heat exchanger to receive heat transferred from the hot water, and a second conduit which bypasses the heat exchanger and delivers cold water directly to the tank. The two inlet conduits are connected to a cold water mains inlet by way of a diverter valve which, in response to the water temperature in the upper region of the tank apportions the water flow between the two conduits. The system enables water to be stored in the tank at a moderately high temperature for demand management purposes and bacterial growth control while minimizing the risk of scalding a user.
