ABSTRACT:
Freeze protected hot water solar heating apparatus for providing room heating and domestic hot water service comprising a solar heat collector, a water storage tank, a freeze protector, a fuel burning boiler, a heat exchanger, in-line sensors, and pumps for circulating the water. The freeze protector is in heat transference contact with the flue of the boiler. The freeze protector, controlled by a temperature sensor, prevents freezing of the water in the solar collector and additionally utilizes waste heat from the flue of the boiler to heat water anytime the boiler is in operation. The boiler is activated, upon the water in the water tank falling below a predetermined temperature. A thermostat controlled fan forces air over the heat exchanger to provide room heating. Check valves are provided for preventing back flow of water from the solar collector. The apparatus may also contain a heat pump having its heat transference coils adjacent to the heat exchanger for full utilization of forced air from the fan.
