Abstract

PURPOSE: To simplify water-draining operation, by providing timer-coordinating type electomagnetic valves on the side of a heat storage tank located at a lower water level than heat-sensing control type water-draining valves.
CONSTITUTION: Electromagnetic valves 12A and 12B, which coordinate with timer 13, are provided on the side of heat storage tank 2, located at a lower water level than water-draining valves 5A and 5B, which are provided on pipe 3A and 3B, which connect solar-heat collector 1 and heat storage tank 2. Set timer 13 in advance so that electromagnetic valves 12A and 12B are closed during the freezing time when solar heat collector 1 is not in use, the circulation of hot water is stopped, and there is danger of freezing the outdoor structure, then, when the atmospheric temperature falls to about 2W3°C during the freezing time, by sensing the water temperature, water-draining valves 5A and 5B open, and only the low temperature water stored in the outdoor part of pipes 3A and 3B, which are located at a higher water level than outdoor solar-heat collector 1 and water-draining valves 5A and 5B, is discharged from water-draining valves 5A and 5B. As a result, the discharge of hot water in heat storage tank 2 is prevented, at the same time, freezing is prevented without aid from the operator.
