PURPOSE:To eliminate a continuous heating of a heating source and enable an easy replacement of the heat exchanger itself in case that a latent heat accumulation material shows a deterioration by a method wherein a heat exchanging between the heat source and the water is carried out through the latent heat accumulation material and at the same time the heat exchanger is removably arranged at the heat generating part of the hot water feeding device. CONSTITUTION:A container 6 of a heat exchanger B is heated and the latent heat accumulation material E is melted and made as a liquid phase. The water is passed through a return pipe 5 by a pump 18, and flowed to the annular heat exchanging chamber 7, connection pipe 9, coiled heat exchanging pipe 8 and a hot water feeding pipe 2. During this feeding of hot water, it is heat exchanged with the latent heat accumulation material E of liquid phase and then fed to the hot water passage 3. In case that the function of the latent heat accumulation material E is deteriorated, the hot water feeding pipe 2 and the return pipe 5 are removed from the projecting sockets 10 and 11, an electrical connection of the thermostats 19 and 19' is turned off and the unit can easily be replaced with a new heat exchanger. |
