<p>PROBLEM TO BE SOLVED: To provide a hot-water storage tank for solar heat collecting device, which employs a hot-water storage tank equipped with an inner tank made of a resin and which has no fear of deterioration in strength even when a temperature/pressure valve or a thermoregulating valve is attached thereto and whose constituting members will not be deteriorated within a short period of time even when a hot-water temperature rises. SOLUTION: Another communicating pipe 22b, positioned at a ceiling unit, is inserted into a small port 28b, formed at a predetermined place of a metallic reinforcing plate 28, while a wax thermo type temperature/pressure valve 23 is attached to the communicating pipe 22b through a mounting fitting 27. A nylon hose 31, extended to the vicinity of a heat exchanger 12, is also attached to the communicating pipe 22b and the temperature sensing unit 23a of the temperature/pressure valve 23 is inserted into the nylon hose 31 while the temperature sensing unit 23a is positioned near the ceiling unit of an inner tank 22 to detect the temperature of hot-water near the ceiling unit.</p> |
