DETAILED DESCRIPTION OF THE ILLUSTRATED EMBODIMENT The solar heating system illustrated in FIG.
1 comprises a solar panel unit 10 for heating a circulating fluid, a fluid storage tank 11, a fluid pump 12, and piping between the pump, storage tank, and solar panel unit for circulation of fluid.
Fluid is drawn from tank 11 through pipe 13 by pump 12.
Fluid from pump 12 is forced into pipe 14, through which, if valve 15 is open, it is directed to solar panel unit 10 for circulation therethrough.
A tee 16 in pipe 14 provides connection to pipe 17, through which, if valve 18 is open, fluid is provided to the location where such fluid is to be used.
This may be to a heat exchange unit in a forced air furnace, a radiator heating system, a heat exchange unit in a hot water tank, or to various other types of equipment where the heated fluid may be advantageously used.
Fluid from the solar panel unit 10 is circulated back to storage tank 11 through pipe 19.
Fluid that has been used by the furnace or other item is returned to tank 11 through pipe 20 which interconnects with pipe 19 at tee 21.
Valves 15 and 18 are preferably electrically controlled valves so that they can be controlled remotely and automatically.
Valve 15 will be open at any time that enough energy from the sun is striking the solar panel unit to make the temperature of the fluid leaving the unit through pipe 19 greater than the fluid entering the unit through pipe 14, i.
e.
the fluid leaving storage tank 11.
This determination will preferably be made automatically by temperature sensors in the output pipe 19 from the panel unit 10 and either in the storage tank 11 or in pipe 13 leading therefrom and by a comparitor to which the outputs of the temperature sensors are connected.
Temperature sensors and comparator units are well known, form no part of applicant's invention, and are thus not described in detail.
Valve 18 will be open at any time heated fluid is needed by the equipment in which such fluid is utilized and may be controlled by, for example, a thermostat in a building to be heated or a thermostat in a water heater
