ABSTRACT:
Batch-type water heating apparatus includes a heat exchanger in which water is heated as it is circulated therethrough, a water storage zone, a flow control device, a water pump, and associated water lines connecting these components to form a closed water circulating loop. Additional water lines associated with the flow control device provide for the withdrawal of heated water from the loop and the addition of make-up water to the loop as water is withdrawn therefrom. The flow control device includes a valve and a thermostat for sensing the water temperature at the outlet of the storage zone. The flow control device is operable to position the valve to facilitate withdrawal of heated water from the loop when the sensed temperature exceeds a predetermined value and to position the valve to facilitate circulation of water around the loop when the sensed temperature is below a predetermined value.
