Water supplied from the outside through the water 2811 is filled with the second water 2512 in the second hot water tank 2502 via the water pump 2800 and the water pipe 2821;
Solar heat collecting water supply, characterized in that. 6. The heat exchanger (2500) according to any one of the preceding claims, wherein the heat exchanger (2500) makes the volume of the first hot water tank (2501) smaller than the volume of the second hot water tank (2502); or
The cross-sectional area of the first heat accumulator 2521 embedded in the first hot water tank 2501 is larger than the cross-sectional area of the second heat accumulator 2522 built into the second hot water tank 2502, and thus, the first hot water tank The difference between the temperature T1 of the first water 2511 filled in 2501 and the temperature T2 of the second water 2512 filled in the second hot water tank 2502 is T1>T2;
Solar heat collecting water supply, characterized in that. The method of claim 1, wherein the collectors 1200, respectively installed in the auxiliary heat collecting plate (100a, 100b) is a rectangular formed in the longitudinal direction on the auxiliary heat collecting plate (100a) (100b). Parallel installations along the opening 130 of the 長方形;
Solar heat collecting water supply, characterized in that. The method of claim 1, wherein at least one rectangular opening portion 130 formed in the longitudinal direction in the auxiliary heat collecting plate (100a, 100b) is provided at least one place. The area of the opening 130 is at least 5 to 30% based on the area of one of the auxiliary heat collecting plates 100a and 100b;
Solar heat collecting water supply, characterized in that. The diameter D1 of any one of the rectangular openings 130 formed in the longitudinal direction in the auxiliary heat collecting plates 100a and 100b is a collector. Equal to the diameter D2 of the vacuum tube 1230 provided at 1200 (D1 = D2); Or the diameter D1 of the opening 130 is smaller than the diameter D2 of the vacuum tube 1230 provided in the collector 1200 (D1 <D2);
Solar heat collecting water supply, characterized in that. The first collection of any one of claims 1, 2, and 5, wherein the sub-collecting plates (100a) and (100b) each of which the collectors (1200) are installed are symmetrically provided in pairs and rotated in the east-west direction. The coaxial 200 is coupled to at least one '+' shape to the second pivot 300 which is rotated in the north-south direction;
Solar heat collecting water supply, characterized in that.
