<p>PROBLEM TO BE SOLVED: To improve mounting workability for constituent parts constructing an electric water heater and for piping, and reducing the manufacturing cost by employing mounting means commonly, and further improving manufacturing quality for the present apparatus together with an improvement of maintenance property. SOLUTION: The electric water heater comprises bath hot water supply means for controlling warm water in an electric warm water unit tank heated to predetermined warm water by mixing tap water and the warm water with the aid of a first mixing valve, and supplying the warm water to a bathtub through a warm water supply passage; and reheating means for sucking the warm water in the bathtub into a pump through a bath return passage with the aid of a pump driven by a motor, raising temperature to predetermined one with a heater surrounding the warm water supply passage. There are integrally mounted on a base member E at least the foregoing first mixing valve 5, a hot water supply solenoid valve 6, a changeover two way valve 12, the pump P equipped with the motor M, the heater 9, and piping 7, 14 for connecting the foregoing respective components. The base member E on which the foregoing components and the piping are mounted is disposed and is anchored in a space h formed between the electric warm water unit tank 1 and a protective package K.</p> |
