Abstract
The disclosure provides a water heater. The water heater includes a water heater main body portion including a heat exchanger and a combustion device; a fan and a motor for driving the fan; an exterior case; and an air supply adapter mounted to an upper wall portion of the exterior case. The combustion device and the motor are positioned in a region near an upper portion within the exterior case. The combustion device is at least partly positioned between the air supply adapter and the fan in a plan view. An air outlet of the air supply adapter opens substantially horizontally, avoiding a direction directly facing the motor. The air flowing out from the air outlet is changed in direction by a side wall portion of the exterior case and flows to reach a portion of the motor.
