Summary: | PROBLEM TO BE SOLVED: To provide a water heater that includes a temperature sensitive valve 9 connected to a water flow conduit 7 and a hot water flow conduit 8 in parallel with a mixing faucet 6, and closing a valve when a temperatures of hot water flowing through the inside is a predetermined temperature or more and cutting off the communication between the water flow conduit and the hot water flow conduit, and a circulating pump 10, the water heater where water is circulated so as to return to the heat exchanger from a heat exchanger 3 through the hot water flow conduit, the return conduit 11, the circulating pump and a water supply conduit 5 by the operation of the circulating pump, and the water is also circulated via the temperature sensitive valve when the temperature sensitive valve is opened, in which the instantaneous water heating operation for operating the circulating pump and burning a burner 2 can be conducted in just proportion.SOLUTION: A flow sensor 14 is interposed in a portion of a downstream side from a connection part with a circulating pump 10 of a water supply conduit 5 or a portion of an upstream side from a connection part with a return conduit 11 of a hot water flow conduit 8. An instantaneous water heating operation is completed when the detection flow rate of the flow sensor 14 is lowered less than a predetermined amount due to the valve closing of a temperature sensitive valve 9 during the instantaneous water heating operation.
【課題】湯水混合栓6と並列に出水管路7と出湯管路8に接続され、内部を流れる湯の温度が所定温度以上のときに閉弁して出水管路と出湯管路との連通を遮断する感温バルブ9と、循環ポンプ10とを備え、循環ポンプの作動により、熱交換器3から出湯管路と戻し管路11と循環ポンプと給水管路5とを介して熱交換器に戻るように水が循環すると共に、感温バルブの開弁時には、感温バルブを経由しても水が循環するようにした給湯装置において、循環ポンプを作動させると共にバーナ2を燃焼させる即湯運転を過不足なく行うことができるようにする。【解決手段】給水管路5の循環ポンプ10との接続部より下流側の部分又は出湯管路8の戻し管路11との接続部より上流側の部分に流量センサ14を介設し、即湯運転中に流量センサ14の検出流量が感温バルブ9の閉弁で所定量を下回ったとき、即湯運転を終了する。【選択図】図1 |
