However, due to the program capacity of the microcomputer 31, the proportional control calculation program for hot water supply cannot be used as is.
It is also possible to adequately control the heating water temperature without incorporating a heating calculation program.

きるから、次のような効果を有する。Effects of the Invention As described above, the present invention provides a hot water supply burner and a heating burner branched from the proportional control valve, and controls each heat exchanger by the proportional control valve drive unit through the hot water supply and heating proportional control calculation units. Since the water temperature can be controlled, it has the following effects.
(1) 給湯・暖房共、一つの比例制御弁で燃焼量を
比例制御して湯温制御をするので、湯温の安定
化が図れる。(1) For both hot water supply and heating, a single proportional control valve proportionally controls the amount of combustion to control the hot water temperature, making it possible to stabilize the hot water temperature.
(2) 特に暖房湯温が比例制御で湯温制御できるの
で、従来のHi−Lo−OFF制御による湯温制御
に比べて、省エネルギ化が図れる。(2) In particular, since the heating water temperature can be controlled by proportional control, energy savings can be achieved compared to conventional hot water temperature control using Hi-Lo-OFF control.
(3) 給湯及び暖房共比例制御演算部の信号により
各々最適の湯温制御ができる。(3) Optimal hot water temperature control can be performed using signals from the proportional control calculation unit for hot water supply and heating.
(4) モード切換処理部の信号により、各々単独制
御と共に、同時使用モードにおいても、給湯側
湯温制御は最適制御できると共に、暖房湯温
も、温水として十分制御でき、給湯・暖房切換
方式に比べ有利である。(4) Based on the signals from the mode switching processing section, the hot water temperature control on the hot water supply side can be optimally controlled both in individual control as well as in the simultaneous use mode, and the heating water temperature can also be sufficiently controlled as hot water, making it possible to use the hot water supply/heating switching system. It is comparatively advantageous.
(5) 燃料通路の部品点数が少なく、湯温制御回路
が一つとなる為、コスト安価となる。(5) The number of parts in the fuel passage is small and there is only one hot water temperature control circuit, resulting in lower costs.
