Patent ·
OSTI ID:6279842

A heat storage system is described comprising an intermittently operating fuel-fired heat engine, a coolant fluid for absorbing the rejected heat of the engine, a path for circulating the coolant fluid between the heat engine where it absorbs heat and a heat transfer zone where it gives up heat, means for forcibly circulating the coolant fluid through its associated path, a storage type potable hot water heater including a tank containing a volume of potable water, a path for circulating potable water between the tank and a heat transfer zone where it absorbs heat given up by the coolant fluid at its respective heat transfer zone, means responsive to the circulation of the coolant fluid to forcibly circulate the potable water through its associated path between the tank and its respective heat transfer zone to produce efficient heat transfer between the heat coolant fluid and the potable water at their respective heat transfer zones.
