The operation of the above construction will be described. When the hot-water tap 27 is opened and hot water is used, the pressure in the tank 3 decreases. In response to this instantly, the pressure sensor 28 detects and sends a signal to the system controller 17. System controller 1
The motor 33 is driven immediately from the result of the calculation from 7, and the valve 32 is opened. This operation is repeated until the set secondary pressure is reached.

When the set secondary pressure is reached, the opening of the valve 32 is maintained to maintain an equilibrium state. When the hot water tap 27 is started to be closed to stop hot water supply, the pressure becomes higher than the set secondary pressure. Therefore, the signal from the pressure sensor 28 causes the motor 33 to close the valve 32 from the system controller 17. Since the pressure is adjusted in this manner, the secondary pressure is constant irrespective of the flow rate as in the characteristic shown in FIG.

When the heater 16 is energized to start boiling, the pressure in the tank 3 gradually increases because the water inside expands. Based on a signal detected by the pressure sensor 28, the system controller 17 drives the motor 39 to slightly open the valve 38. Since the pressure rise due to the expansion is so small that the pressure drops again, the motor 39 also closes the valve 38 by the controller 17. By repeating this, the relief valve set pressure becomes the characteristic shown in FIG. 3B, and the secondary water supply pressure does not change even if the hot water flow rate is increased.

Next, the operation of the remote control will be described. At first, the inside of the tank 3 is empty, and at this time, the electric pressure reducing valve 21 is fully closed. For example, when the manager informs the manager that the next day will come, the manager checks the control panel 1
3 is operated to start operation. Upon receiving this signal, the system controller 17 fully closes the electric relief valve 24 and fully opens the electric pressure reducing valve 21 to start supplying water to the tank 3. At the same time, the pulse signal from the flow sensor 22 is integrated, and when the tank 3 becomes full and the pulse signal stops, it is determined that the tank 3 is full, and the heater 16 is energized and the water is heated to a predetermined temperature. In this state, wait for the user to come to the room. When the user returns, when the manager is informed of the fact, the switch on the control panel 13 instructs the stop of the water heater. Upon receiving this signal, the system controller 17 fully opens the electric relief valve 24 and fully closes the electric pressure reducing valve 21 to start draining the tank 3. In this way, when not in use, the system corresponds to a use system in which the inside of the tank 3 is kept empty to wait for the next visit.

As described above, in the hot water supply type water heater of the embodiment, since the electric pressure reducing valve 21 and the electric relief valve 24 can use the electric water supply valve 6 and the electric water discharge valve 12, the number of valves can be reduced. At the same time, the piping configuration is simplified, and piping work can be greatly reduced.

If only the pressure sensor 28 is provided at the upper part of the tank 3, a high secondary pressure can be secured, and the electric pressure reducing valve 21 and the electric relief valve 24 can be mounted at arbitrary positions. If it is arranged near the water supply port 19 at the lower part of 3, the piping distance can be made extremely short, and a simple and reasonable water supply pipe can be made.
