PURPOSE:To obtain high-temperature hot-water, permit low-temperature hot- water reservation and reduce heat radiating loss by a constitutiion capable of circulation heating and re-heating. CONSTITUTION:A heating circuit is formed by connecting a sending pipe 10, a heat source 5a, a temperature thermistor 11a, a solenoid valve 12, a circulating pump 4 and a returning pipe 13 sequentially from the upper end of a hot-water reserving tank 3, equipped with a water feeding pipe 2 at the lower part thereof, and connecting the terminal of the returning pipe 13 to the other lower part of the hot-water reserving tank 3. The heat source 5b and the temperature thermistor 11b are provided in parallel to the heat source 5a and the temperature thermistor 11a while a hot-water outlet pipe 1 is taken out from an intermediate part between the temperature thermistors 11a, 11b and the solenoid valve 12. Thus, the constitution capable of circulation heating and re-heating is accomplished and not only the high-temperature hot-water may be obtained but also the low-temperature hot-water reservation may be effected, therefore, the heat radiating loss may be reduced. |
