<p>PROBLEM TO BE SOLVED: To provide a solar heat utilizing device which can equalize the water temperature within a hot water tank and can enhance the heating efficiency especially in heat supply mode, and in its turn can save the quantity of heat supplied from an auxiliary heat source. SOLUTION: A solar heat utilizing device is equipped with a hot water tank 10, a solar heat supply system 20 which collects solar heat and warms the water within the hot water tank 10, and a heat entry and delivery system 30. The heat entry and delivery system 30 has a heat takeout mode where it takes out the heat of the hot water tank 10 by heat exchanger 31 and sends it to toad 40 and a heat supply mode where it supplies the heat of the auxiliary heat source 34 to the hot water tank 10 through a heat exchanger 31. The heat exchanger 31 is provided with an agitator 50, and the water in the hot water tank 10 is agitated by this agitator 50.</p> |
