ABSTRACT:
A solar water heating system for heating water in a solar panel and storing it in a water storage tank includes a pump which circulates the water in the system, from the water storage tank through the solar panel and back to the water storage tank; a freeze protection means permits water to bleed off from a location between the solar panel and water storage tank when the pump is off to maintain a flow of water through said solar panel and connecting parts thereof which are located in an area where freezing can be encountered. Means are provided to turn the pump on and off and a backup heating device is located in the water storage tank, such as an electrical heating unit, to provide heat when there is not sufficient solar energy. When a timer is used to turn the pump on and off if during some period when the pump is on the water in the solar panel is not heated, the cold water in the bottom of the water storage tank is merely recirculated in a manner having a minimal effect on the warmer water in the upper part of the water storage tank. While a timer has been referred to, a photovoltaic panel can be used to control said pump.
