In the water heater, a burner is provided in a combustion chamber which is below a hot water storage chamber that is an all primary air burner which takes in the air required for gas combustion, whereby the air is mostly primary air. In addition, the burner is provided with a supporting plate in the combustion chamber at a height that allows part of the burner head to be protruded into a space covered by a lower mirror plate.
