ABSTRACT:
A solar energy system in which a heat transferring liquid captures heat in solar collectors and stores it in a storage tank is disclosed. A pump moves heat transferring liquid from the storage tank to the collectors and into a drain-back module only when a predetermined activation temperature is achieved. The pump then inactivates allowing heat transferring liquid within the collectors to heat. When the pump initially inactivates, a siphon or draining cycle is formed which moves heat transferring liquid from the drain-back module to the storage tank. Gas within the storage tank replaces heat transferring liquid in the collectors through the drain-back module to achieve drain-back. However, the siphon or draining operation must first cause heat transferring liquid within the drain-back module to fall below a drain-back feed point. Thus, the solar energy system delays drain-back until after the siphon or draining operation is completed.
