Abstract
A hot water heater comprises a vessel, a heating means for heating water in the vessel, and a control conduit for diverting cold water from the cold water inlet to the hot water outlet so as to reduce the temperature of the hot water delivered from the vessel but to increase the volume. The heater includes a control means for selectively energizing the number of heating elements in accordance with the temperature of the water in the vessel. When the heating means comprises a gas burner, it is arranged to direct combustion gases towards one side of the vessel so as to establish a convection current within the vessel. A novel flue arrangement is also disclosed.
