ABSTRACT:
A water heater includes a housing, an air box, two windproof hoods, and a catalyst converter. Thus, the catalyst converter converts the carbon monoxide produced during the combustion process of the burner into the carbon dioxide and the water, thereby preventing the waste gas containing the carbon monoxide from causing danger to a user so as to protect the user's safety. In addition, the waste gas containing the carbon dioxide is drained outward from the drain pipe, thereby preventing the waste gas from being gathered in the closed room.
