The invention relates to a water heating system in which a single water heater is utilized in combination with a storage tank and pump to provide hot water for various uses. The invention is particularly directed to the use of a thermostatic mixing valve set at a predetermined temperature and located at a juncture between a recirculating conduit from the water heater and the conduit for the flow of water from the storage tank or a source of fresh water supply to the water heater so that water which has already been heated by the water heater may be mixed with the colder water supplied to the water heater to be heated.
