Abstract
A hot water supply system has a tank divided into a water heating chamber and a vented expansion chamber. A venturi orifice inlet is connected through a faucet valve to a cold water supply and the outlet of the orifice emits a high velocity jet at a negative pressure to cause water to be aspirated from the expansion chamber and mix with the supply water jet for pressurizing the heating chamber to cause hot water to be dispensed from the faucet spout, connected to the tank heating chamber, when the valve is opened. An air collection chamber receives the supply water jet stream which flows into the heating chamber until the expansion chamber is emptied of water for air to be aspirated into the collection chamber in which case the jet is disrupted and aspiration of air stops although the flow of water into and out of the heating tank can continue as long as the faucet valve remains open.
