ように表わせる。水温をTW、供給湯温をTH、出湯温度を
TS、水量をQW、供給湯量をQH、出湯量をQSとすると
（１）式が成立する。The ratio W of the amount of water and the amount of hot water when hot water is being supplied at the set temperature can be expressed as follows. The water temperature is T W , the supplied hot water temperature is T H , the hot water temperature is
T S, the amount of water the Q W, the supply quantity of water Q H, when the hot water amount is Q S (1) equation is established.
THQH＋TWQW＝TSQS （１） ここでQSは（２）式で表わせる。T H Q H + T W Q W = T S Q S (1) Here, Q S can be expressed by equation (2).
QS＝QH＋QW （２） したがって（１）式と（２）式よりＷ＝QH/QWは（３）
式のように表わせる。Q S = Q H + Q W (2) Therefore, from formulas (1) and (2), W = Q H / Q W is (3)
It can be expressed as a formula.
この流量比Ｗで第１の駆動手段15および第２の駆動手段
17を駆動し、水側弁12および湯側弁13の弁開度を調節す

12 is first driven by the first drive means 15 and the mixed hot water temperature detection means 18
To detect the water temperature.
供給湯温は湯側弁の上流にある供給湯温検出手段24で検
出する。The supply hot water temperature is detected by the supply hot water temperature detecting means 24 upstream of the hot water valve.
このようにして求めた水温と供給湯温を（３）式に代入
することにより任意の設定温度での流量比Ｗを求めるこ
とができる。By substituting the water temperature and the supplied hot water temperature thus obtained into the equation (3), the flow rate ratio W at an arbitrary set temperature can be obtained.
したがって流量比Ｗで第１の駆動手段15と第２の駆動手
段17を駆動し水側弁12と湯側弁13を開いていけば出湯直
後より設定温度給湯が可能である。Therefore, if the first drive means 15 and the second drive means 17 are driven at the flow rate ratio W and the water side valve 12 and the hot water side valve 13 are opened, it is possible to supply hot water at the set temperature immediately after tapping.
