PROBLEM TO BE SOLVED: To provide a delivery means of a motor driven hot water feeder which has a good space efficiency since motors are not provided for individual parts, and which permits a complete shaft seal. SOLUTION: This motor driven hot water feeder has a hot water storage tank 1 for storing hot water, rotary blades 7 for feeding the hot water in the hot water storage tank 1, and a control circuit 5 positioned on the outside of the hot water storage tank 1 by means of appropriate support means. The rotary blades 7 and the rotor 10 of an electric motor are integrated together and a stator 6 is mounted on the control circuit 5 outside the hot water storage tank 1 so as to achieve the configuration of an electric motor as a whole, thereby eliminating the need for conventional magnet couplings and individual motors and enhancing space efficiency. Since the stator 6 is mounted on the control circuit 5, any especial wiring is unnecessary and the assembling property of the feeder is improved. Further, since no axial coupling is made between a water passage and the outside, water sealability can be kept as good as those of conventional feeders.
