Abstract
A water heater includes a housing, an air box, and two windproof hoods. Thus, the waste gas produced by the burner is drained outward smoothly and regularly even when the air current of the ambient environment is disposed at an abnormal and unstable state, so that the water heater has an enhanced air circulation, thereby facilitating operation of the water heater. In addition, the drain pipe is protected by each of the two windproof hoods to achieve a windproof and rainproof effect.
