Abstract
An apparatus for heating water with solar radiation incorporates an auxiliary heating unit, external to the hot water reservoir and bypassing the solar heating element, for providing auxiliary water heating whenever the temperature in a selected portion of the reservoir decreases below a predetermined level. A common return conduit in combination with a single supply pump and a selector valve enable the auxiliary heating 'by-pass' circuit to be simply and quickly added to already existing installations.
