PURPOSE:To enable to supply hot-water of a proper temperature by a method wherein a constant volume water feeding means, in which an automatic feeding is never effected after a set volume of water is fed even if much water is used for supplying the hot-water, is used and water feeding operation is begun after the set volume is determined by an user estimating the weather of a day in every mornings. CONSTITUTION:The heat accumulating tank 11 of the solar heat collecting device is provided with a water feeding port 12 at the upper part thereof and a hot-water supplying port 15 at the lower part thereof while the constant volume water feeding means 14, automatically stopping the water after the set volume of water has been fed, is arranged on the way of a water feeding path for the water feedingport 12. As a result, the capacity of the heat accumulating tank 11 can be changed, therefore, the temperature of the supplying hot-water, higher than the set temperature, may be obtained even if the amount of the supplying hot-water is changed, direct dropping hot-water supply may be effected in a cloudy day or in winter, the device may be used every days except a rainy day and the employing efficiency may be increased. It is simple to estimate the weather of the whole of the day in the morning of the day using the hot- water, even in ORDINARY homes, and,therefore, a heat-up temperature of the water will never be made short by mistake. |
