To explain what is shown in Figure 1, the water supply pipe 6
A water flow rate sensor 7 and an incoming water temperature sensor 8 are installed in the hot water supply line 2, and an outlet hot water temperature sensor 9 and a water flow valve 4 are installed in the hot water outlet pipe 2, and the flow rate Q detected by the water flow rate sensor 7 and the water temperature Tc detected by the inflow water rate sensor 8 are set. Temperature Ts
and the thermal efficiency η of the heat exchanger 10, the feed forward gas amount F 1 is calculated using the formula F 1 =Q×(Ts−Tc)/η, and the outlet hot water temperature T H detected by the outlet hot water temperature sensor 9 is calculated. , set temperature Ts, and proportional gain (constant)

It branches on the downstream side of the valve 4 and directly connects to a water faucet 11 such as a hot water mixer faucet, or connects to the shower 5 via the hot water mixer faucet.

然る処、上記従来のガス給湯機は下記の如き問
題があり、シヤワーが非常に使い難く、2箇所給

However, the above-mentioned conventional gas water heater has the following problems: the shower is very difficult to use, and it is difficult to supply hot water at two locations.

If you use the shower first and then use the faucet in the other hot water supply pipe, if the shower is in use and the water heater is at its capacity limit, you can use the other faucet to get hot water. Naturally, the water flows through this faucet as well, instantly reducing the amount of hot water on the shower side. As a result, the water temperature in a shower that mixes water at a mixing faucet based on the initial amount of water drops rapidly.

又シヤワー使用状態が給湯機の能力限界以
下であつても、他方の水栓を使用し、能力を
越えた場合も上記と同様の問題が生じる。
Further, even if the shower usage is below the water heater's capacity limit, the same problem as above will occur if the other faucet is used and the capacity is exceeded.

シヤワー使用状態が給湯機の能力限界以下

温が下がる。
Even when the shower is being used below the water heater's capacity limit and the other faucet is used, if the required heat load for both is within the water heater's capacity limit, the pressure loss on the shower side will be greater than that of the other faucet. Because it is large, hot water easily flows to the other faucet side, and the amount of hot water on the shower side instantly decreases, causing the water temperature to drop.

シヤワー側、水栓側双方を使用していて、水
栓側を止めた場合、 双方使用の状態が給湯機の能力限界いつぱ
いであつた場合、水栓側が止められれば、水
栓側に流れていた湯は当然瞬間的にシヤワー
側に流れようとするので、シヤワー側の湯量
は増加し、混合湯温は高くなる。
If you are using both the shower side and the faucet side and turn off the faucet side, and if both are in use and the water heater is at its capacity limit, water will flow to the faucet side if the faucet side is turned off. Of course, the hot water will instantly flow to the shower side, so the amount of hot water on the shower side will increase and the mixed water temperature will rise.

又、双方使用の状態が給湯機の能力限界以
下である場合にも上記と同様の問題が生じ

Further, the same problem as above occurs when the state of use of both is below the capacity limit of the water heater.

双方使用の状態が給湯機の能力限界を越え

If the water heater's capacity limit is exceeded when both are in use, the water flow valve is normally throttled, so if the faucet is turned off, the amount of hot water flowing to the shower will decrease by the amount that is throttled. do. In other words, the rise in the mixed water temperature is also alleviated by that amount.
