Abstract: A water heater includes a combustion device, a primary heat exchanger, and a secondary heat exchanger. The combustion device burns gas to generate high-temperature air. The primary and the secondary heat exchangers are provided sequentially above the combustion device. When the high-temperature air passes through the primary heat exchanger, part of thermal energy is absorbed by exchange plates and a water pipe therein. When the high-temperature air continues to pass through the secondary heat exchanger, part of the rest thermal energy is absorbed by a heat tube set therein to preheat water flowing through the heat tube set. The preheated water then flows into the water pipe of the primary heat exchanger. The secondary heat exchanger includes a case and a cover board which detachably seals a bore on the case. Whereby, it's convenient for a user to clean pipes inside the secondary heat exchanger.
