The Wood Water Heater utilizes a sophisticated heat exchange design for efficient water heating. The Aluminum stove body surrounding the firebox is a double-walled water-jacket with a 1.5-inch space between, making the entire firebox (except the front) a heat-transferring surface. Additional heat transfer takes place in a water-filled flat baffle tubes that runs horizontally through the firebox. The baffle deflects the path of the fire, so it gives up more heat into the water jacket before going up the chimney.
Heat is easily controlled by adjusting the air draft control for heating the water and maintaining the water temperature.
