ABSTRACT:
A solar hot water heating system has a primary tank heated by solar energy utilizing a heat transfer medium circulated between a solar collector and a heat exchanger located in the primary tank. Usually a back-up tank is provided to supplement the solar system. The primary tank receives cold water from a pressurized source. Its hot water outlet is connected to a heating and storage back-up tank the outlet of which supplies hot water to a domestic water supply, or the like. A pressure-actuated valve responds to a condition of the medium. When a predetermined temperature is reached the valve opens to release water from the system thereby permitting surplus hot water from the primary tank to replace the released water and thus reduce back-up energy requirement.
