ABSTRACT:
Prior inventions in 2-tank solar heat-storage systems, generally speaking, provide for solar-produced heat stored in a first tank. Therefore STORED solar heat is limited to that one tank. Backup heat is produced and stored in a second tank. In the present invention, SOLAR-PRODUCED heat from said first tank flows to said second tank. No pump is used. No pump-control is used. No valve is used. Flow is automatic, by natural thermosyphon action when the temperature in said first tank exceeds the temperature in said second tank. AND, the EFFECTIVE storage of solar-produced heat is much greater. Moreover, heat from said second tank, which usually contains the backup heater(s), does not flow from said second tank back to said first tank. There is no reverse flow and no waste of backup heat energy when the temperature in said second tank exceeds that in said first tank. In order to achieve these desirable results the second tank may be placed at a higher elevation, and the plumbing connections are made so as to automatically transfer the heat one way only. Stratification assures that hot water is on tap, and also assures that solar heat is applied to the coldest water, which can be heated with greatest efficiency of solar heat collection. Also, the hot/warm liquid from stored solar heat and/or the backup heater is used and/or circulated in a unique manner and with apparatus which delivers warm and/or hot water to several points of use at different temperature levels and flow rates.
