Abstract

A low-pressure hot water supply unit (1 ) is provided comprising a low- pressure water heater including a storage tank (3, 31 ) wherein the water heater has associated with it a low-pressure cold water supply container (4, 21, 52, 41). The unit has an overflow or relief outlet (1 1 ) communicating with the interior of either the cold water supply container thereby enabling overflow from the storage tank to form part of a cold water supply or a separate collection chamber (20, 30) communicating with the storage tank. The low-pressure water heater preferably has a cold water supply container carried on top of the water heater. The water supply container typically has a float controlled valve (5) associated therewith for maintaining a predetermined minimum water level (6) within the cold water supply container. The inlet passage supplying water from the cold water supply container to the lower region of the storage tank of the water heater is preferably configured to form an anti-thermo-siphon loop (8a). The low- pressure water heater may be a solar water heater or a solar assisted water heater.
