Abstract
A hot water heater has an expansion tank below the water tank and aligned with the water tank, so both water tank and expansion tank occupy the same floor space. The expansion tank is connected to the water tank by a pipe, so expansion due to heating of the water is absorbed by the expansion tank. For gas fired heaters, the burner for heating water in the water tank is disposed above the expansion tank and below the water tank, so the burner is above the floor sufficiently to comply with gas safety regulations.
