ロスが多かった。Conventional configuration and its problems For example, in a conventional gas boiler with an integrated heat source,
Once the amount of hot water stored in the tank was used up, all that could be obtained was water, and it took a lot of time to boil the water to the specified temperature in the hot water tank. In addition, it is necessary to boil the upper part of the hot water tank from the heat source, which means that it is necessary to boil almost the entire capacity of the hot water storage tank, resulting in a large amount of energy loss when the load is small.
発明の目的

目的とする。Purpose of the Invention The present invention solves the above-mentioned conventional drawbacks, and uses an instantaneous water heater as a heat source to shorten the time to raise the P part, reduce the probability of running out of hot water, and change the setting of the amount of hot water stored. By doing so, the purpose is to improve usability and save energy.

のである。After that, when it is fully detected that the set temperature has dropped, hot water is sent into the hot water tank again.
By using the hot water as a source, a stable hot water temperature can be obtained, and when hot water is tapped, the hot water inside the hot water storage tank and the water leaking from the water heater can be used, so the amount of hot water that exceeds the capacity of the hot water storage tank can be used. In addition, since the boiling rate can be set, it has the effect of storing a large amount of hot water when a large amount of hot water is used, and storing a small amount of hot water when the amount of water used is small, such as at night. be.

湯する。(1) During boiling Since there is no hot water coming out of the boiling water, there is no outflow from the hot water outlet pipe 6 and no inflow from the water inlet pipe 7. In this figure, the boiling amount setting is in two stages, and when the total amount is set to ``2'', the boiling amount selector switch sends a signal from the boiling amount setting section 22 to the hot water tank control section 24 to indicate the ``full amount increased''. sent to hot water temperature detection sensors 28 and 29
only works now. In the case of raising the amount by half, similarly, only the hot water control sensors 26 and 27 operate. Here, we will explain the full amount. The temperature of the hot water temperature detection sensor 28 and the temperature set by the hot water pan setting volume 21 are compared with the command generation glj 25, and if the by-product of the hot water temperature detection sensor 28 is T++T2°C lower than the setting, lK, - command is issued.

8. When the pump a9 goes to sleep 11', the water heaters 3 and 4 are fired.At this time, if the pump is not turned on, the water will not burn and the hot water will not be heated. Along with the combustion of the boiler, the fuel filling control section 16
．． 17 is the hot water 7□1■φ′f, (1 sesser io, 11
By comparing the temperature of the water heater with the set temperature and controlling the gas flow control valve, the hot water output from the water heater is kept at the level set at 3°4. While the water heater is in combustion, the temperature of the sensor 29 is compared with the set temperature, and when the cu degree of the sensor 29 reaches the set temperature - 1°C, the combustion is stopped, and at the same time, the next compares the temperature of the sensor 28 with the set temperature, and by repeating this operation, the hot water storage temperature is set to the entire set temperature.
Keep it at 1. When the d1 raising selector switch is set to half the amount, the hot water is stored in the same way as the full amount raising described above with the hot water temperature adjustment switch 26.27.
