<p>PURPOSE:To obtain hot water to be supplied at a stable set temprature in a short time by fitting a temperature detector detecting the mean temperature of a piping connecting a hot-water storage type hot-water supply machine and a hot-water supply cock extending over the total length of the piping and operating a mixing valve mixing hot water supplied and feedwater on the basis of the signal. CONSTITUTION:The hot-water storage type hot-water supply machine is provided with a hot-water storage tank 1, a burner and a heat exchanger 2, a hot-water temperature detector 3, an exhaust cylinder 4, a water-supply port 5 and a hot-water discharge port 6, and an opening and closing valve 8 set up a gas feed duct 7 is operated by a signal from the hot-water temperature detector 3 and the temperature of hot water is kept at set value. The mixing valve 9 is fitted near the hot-water discharge port 6 while being connected to the water-supply port 5. The temperature detector 12 detecting the mean temperature of the piping 11 connecting the mixing valve 9 and the hot-water supply cock 10 is mounted extending over the total length of the piping, and a controller 13 operating the mixing valve 9 by the signal from the temperature detector 12 and set value is set up. Accordingly, the mean temperature of the piping 11 is detected and the mixing valve 9 is adjusted, and hot water supplied at the stable set temperature is obtained in a short time.</p> |
