| description | PROBLEM TO BE SOLVED: To provide a hot water supply device capable of surely determining scale clogging by a simple method.SOLUTION: A hot water supply device 1 includes a fin and tube type heat exchanger 21 for heating clean water by a combustion gas, and a heat exchanger can body 22 for accommodating the heat exchanger 21, and further includes a temperature detection sensor 31 for detecting a surface temperature of the heat exchanger can body 22, and a control unit 7 determining accumulation of scale in a heat transfer tube 27 of the heat exchanger 21, when the detection temperature detected by the temperature detection sensor 31 becomes a set temperature or higher.
【課題】給湯装置において、簡単な方法によってスケール詰まりを確実に判定可能なもの、等を提供することである。【解決手段】給湯装置１は、燃焼ガスによって上水を加熱する為のフィンアンドチューブ型熱交換器２１と、この熱交換器２１を収納する為の熱交換器缶体２２とを備え、熱交換器缶体２２の表面温度を検知する為の温度検知センサ３１と、この温度検知センサ３１によって検知される検知温度が設定温度以上になった場合に熱交換器２１の伝熱管２７内にスケールが堆積していると判定する制御ユニット７とを備えている。【選択図】図２ |
