PURPOSE:To enhance the heat exchange efficiency of the heater by a method wherein the heater comprises sealing the latent heat type heat accumulating material and working liquid, the specific gravity at the melting point of which is larger than that of the heat of the heat accumulating material within the heater. CONSTITUTION:The latent heat type heat accumulating material 2 and the working liquid 3, the specific gravity at the melting point of which is larger than that of the heat accumulating material in the molten state, are sealed within the case 1 of the water heater, at the lower part of which a heater 5 is provided and at the upper part of which a heat exchanger 4 is provided. As an example, sodium acetate trihydrate is employed as the heat accumulating material and Freon R-113, which is non-compatible and non-reactive with sodium acetate trihydrate, is used as the working liquid. |
