<p>PURPOSE:To enhance a heat exchanging efficiency by providing a gas/liquid contact part in contact with exhaust gas of a hot water supply burner in a water (hot water) supply passage to a part to be supplied, and injection water (hot water) from an upstream side of exhaust gas in a flowing direction to a downstream side to the contact part. CONSTITUTION:A hot water supplying apparatus comprises a hot water supply unit for supplying hot water to a bathtub, a hot water supply cock, a reheater for bath temperature keeping function for reheating bathtub water, a gas/liquid contact part G for bringing water or hot water into contact with exhaust gas of a hot water supply burner of the hot water supply unit, and a water reservoir F for water-sealing a passage part from the contact part G to the bathtub. The contact part G is connected. with an exhaust gas duct 12 of the hot water supply unit, and connected with a hot water passage W2 to be guided with hot water from the hot water supply unit and a water supply passage W3. The water supplied via the passage W3 is injected from an injection nozzle 16 along an exhaust gas flowing direction, heat exchanged with a charged layer 17 formed by knitting in a stereoscopic lattice state and to be heated with exhaust gas, and raised at its temperature, and exhaust gas is discharged from an exhaust port 18.</p> |
