<p>PURPOSE:To provide an electric hot water apparatus which does not impair the usability and maintenance property by providing an electrical equipment portion at the upper part of either one of the right and left of a space between the outer surface of a hot water storage tank and the inner surface of an outer frame encircling said outer surface, providing a water feed pipe line at the lower part thereof, and disposing a hot water feed pipe line at another. CONSTITUTION:A high temperature side pipe line constituted of a hot water pipe line 7, a relief valve 8, a relief pipe line 9, and an exhaust cock 10 is located at the left side of a front part in a space between a hot water storage tank 1 and an outer frame 16, an electri cal equipment portion 3 is located at the upper part of the right side thereof and a low temperature side pipe line constituted of a water feed pipe line 4, a pressure reducing valve 5 for service water, and a water feed tap 6 is located at the lower part of the electrical equipment portion 3. Thus, the electrical equipment portion 3 does not give rise to problems of erroneous operations, damages of electronic parts, and the like by the influence of heat from the high-temperature side pipe line such as the hot water feed pipe line 7 or the like. By disposing the lower temperature side pipe line such as the water feed pipe line 4 or the like at the lower part of the electrical equipment portion 3, the cooling effect is enhanced. Even if water leaks out of the pipe line part, the electrical equipment portion 3 is kept in a position where it is not exposed to water. Therefore, there is no problem in the safety and reliability.</p> |
