<p>PROBLEM TO BE SOLVED: To provide a water heater capable of efficiently supplying hot water without generating dangerous combustible substances and of inhibiting the deposition of scale or the like in the pipe. SOLUTION: A water heater 1 is provided with a hydrogen fuel burner 6 serving as the heat source for the endothermic exchanger 4 of a compressor 3. The burner 6 keeps the heating medium at a constant temperature, and this heats the circulating water efficiently to the specified temperature before being supplied to the outside. Since the circulating water passes through a water quality improving filter 7 before being heated, iron and salts remaining in the water are not to be separated easily, which inhibits or avoids the deposition of scale on the pipe or the like.</p> |
