Abstract
According to the hot water supply apparatus of the present invention, it becomes possible to effectively prevent the dew condensation on a bypass line. While exhaust gas after passage through a heat exchanger 2 is passing through an exhaust gas collection section 14 and then through an exhaust gas tube 15, combustion air in the inside of an inlet air tube 16 and a supply air collection section 17 is heated by heat exchange. A bypass line 19 which connects together a water supply line 3 and a hot water supply line 5 is disposed so as to pass through a clearance 20 defined between a supply air duct 18 which supplies heated combustion air to an air sending fan 6 and a burner casing 10 whereby the bypass line 19 is heated by the heat of combustion air in the inside of the supply air duct 18. Alternatively, the bypass line 19 may be disposed and placed so as to pass through the inside of the supply air duct 18.
