PURPOSE:To obtain a plenty of hot-water instantaneously and continuously by a method wherein a necessary amount of water is injected for passing continuously at the same time through the whole heat absorbing area into both of up and down directions with different flow speeds and absorb the heat efficiently as the water is washing the heat absorbing surface. CONSTITUTION:When a faucet 37 is opened, about one fourth of the city water flowing out of the faucet is passed through a hose 63 and is entered into a heat exchanger 16, provided in a chimney, and a heat absorbing chamber 20 to absorb the heat. Subsequently, the hot-water is injected against fin plates 4 from the end of a water releasing tube 23 to absorb the heat of the plates, thereafter, is injected inbetween the heat exchanger 2 and a cover 9 with the flowing speed of V1. On the other hand, the city water, flowed out through the hose 62, is flowed into the heat exchanger b with the flowing speed of V2 to absorb heat as it is flowing upwardly while the city water, injected from a water injecting port 65, is passed through a lower circulating pipe 66 to enter into the heat exchanger 2 to absorb the heat as it is flowing upwardly. |
