する。Assuming that this output is 4V at maximum, the -reference for each of the amplifiers 18, 19, and 20.21 is OV
, IV, 2V, and 3V, and if the output is 0.6V, an output of 0.6V will be output from the operational amplifier 18, and with these o and sV signals, the drive circuit 23 of the gas volume control valve will
3Ai7) The gas amount control valve 24 is controlled by the valve opening degree. At this time, the combustion start circuit 25 starts the combustion sequence of the first boiler 5. 1. Also, here, the gas amount control valve is fully open when the output signal of the operational amplifier is 1V.
The moment when the output signal is output from 0 is controlled at the minimum combustion amount. Furthermore, it is possible to control steplessly between 0 and 1v. Next, the output from the difference detection circuit 17 is 1.5V.
In this case, the gas amount control valve 24 is fully open and the gas amount control valve 32 is controlled to an opening degree of %. At this time, the second water heater 8 starts combustion by the combustion start circuit 27.

このように、差検出回路１７からの出力に応じて１台目
が、最少燃焼量で、着火し出力に応じて着火し出力に応

同じ様に動作して行く。In this way, the first engine ignites with the minimum combustion amount according to the output from the difference detection circuit 17, ignites according to the output, and reaches the maximum combustion amount according to the output. Furthermore, the third and fourth devices operate in the same manner.

火する。Next, as the load decreases and the output from the difference detection circuit gradually decreases, the fourth engine first reaches the minimum combustion amount. At this time, the stop circuit 31 is operated until the output from the third operational amplifier 20 becomes 0, causing the fourth operational amplifier to continue combustion at the minimum combustion amount. The third operational amplifier is
When it reaches 0, the fourth fire goes out. Similarly, when the output of the second operational amplifier 19 is 0, the third operational amplifier 19
When the output of the second operational amplifier 18 is 0, the second operational amplifier 18 extinguishes the fire.

消費は熱交換にほとんど寄与せず、かつ冷えた湯沸器を
再びあたため直すのにガスを消費し、消費量のわりには
湯の温度が上昇しないからである。The first unit extinguishes the fire when the output of the operational amplifier 18 continues to be 0 for several tens of seconds. This is driven by a timer circuit 23. By operating like this, the detection circuit 1
For example, if the output of the 7 repeatedly changes between o, 9v and 1.2v in a short period of time, the second unit will repeatedly ignite and extinguish the fire after reaching 1v. This is because the loss in combustion efficiency at this time is very large and results in a wasteful use of gas. This is because gas consumption during ignition hardly contributes to heat exchange, and gas is consumed to reheat a cold water heater, so the temperature of the hot water does not rise in proportion to the amount consumed.

駄な使用は、なくなる。In the case of the present invention, 1v1f:, boundary 2, 0.9V and 1.2
Even if the output is repeated between V and 9V, the second unit is still burning at the minimum amount of combustion even when the output is 9V, so even if the output changes to 1.2V, the amount of gas will only change. Since the fire is not ignited after being extinguished, the combustion efficiency is good and wasteful use of gas is eliminated.

３７に入れる。In the above operation, when the sensor 35 that detects the temperature difference between water and hot water, the differential circuit 36, and the addition circuit 37 are operated, the hot water that is combined with the water supplied from the dustern 39 enters the hot water header 1, and the setting is performed. When the temperature sensor 36 detects a suddenly low water temperature, this detection signal is input to the differentiating circuit 36, and this output signal is input to the adding circuit 37.

This sensor 35° differential path 36. By providing the addition circuit 37, it is sensor 1 and sensor 2 that originally detect the hot water that has become low;
Even if each water heater operates after the detection, during the transitional period of change, the low-temperature hot water from part A to sensor 2 passes through without being heated. This creates a difference in the temperature that comes out of the hot water tap. However, if the water heater is combusted before reaching sensor 2 as in the present invention, low-temperature hot water will not pass between section A and sensor 2, and a stable hot water temperature will be obtained from hot water faucet 4o. It is something that can be done.
