PURPOSE: A solar heat system is provided to quickly supply heat accumulated by a solar heat collector to heating and hot water supply mechanisms and to secure stable and efficient operation. CONSTITUTION: A solar heat system a solar heat collector(10) which absorbs solar energy and heats thermal media, a heat storage tank(20) which accommodates heating water and includes first and second heat storage heat exchangers(21,22) connected to the solar heat collector through heat storage pipes and diffusers for diffusing returned heating water, a pressure sensor(13) which is connected to the heat storage pipes to detect the internal pressure of the heat storage pipes, a circulation pump(14) which circulates the thermal media, a thermal medium supplement tank(50) which is connected to the heat storage pipes via a pressure pump(15) and supplements thermal media to the heat storage pipes, an auxiliary boiler with a heating water outlet connected to a heating water supply pipe of the heat storage tank and a heating water return port connected to the diffusers of the heat storage tank, a check valve(43) which is connected between a heating water supply control three-way valve and the heating water return port of the auxiliary boiler, and a heating load(40) which is connected between the heating water outlet and a heating water return control three-way valve(V1~V4) of the auxiliary boiler. |
