Abstract
The energy required to provide hot water may be reduced in a water heating system including a heat generating range (12) for cooking food and a hood (14) overlying the range (12) for capturing fumes rising from the range (12) or the food thereon. An exhaust duct (16) provided with an exhaust fan (18) is connected to the hood (14) and a baffle and heat exchanger assembly (22) is interposed between the hood (14) and the exhaust duct (16). The assembly (22) includes a grease collecting baffle (54) facing the hood (14) and a heat exchanger (52) backing the baffle (54). The heat exchanger (52) includes a liquid flow path (56), (60), (74) through which water to be heated by the fumes may circulate.
