Abstract: A water heater having improved operating characteristics and lower costs of manufacturing is described. The water heater has an unified combustion chamber and burner construction with a ceramic fiber matrix burner.

Abstract: A water heater includes a tank and an exhaust blower is located below the tank and connected to the exhaust line to draw the combustion products by suction through the coil-shaped heat exchanger, through the combustion gases conduit and through the combustion chamber and to draw fuel and air into the burner through the inlet conduit.

Abstract: An outside balanced flue water heater including a water tank; a jacket surrounding the water tank; a combustion chamber containing a burner positioned adjacent the water tank; a flue extending from the combustion chamber through an upper portion of the water tank; a water inlet and a water outlet connected to the water tank; a combustion air passageway positioned between the jacket and the water tank, the combustion air passageway communicating with the combustion chamber to supply combustion air from the combustion air passageway to the combustion chamber; a combustion air inlet chamber above the water tank and adapted to directly receive outside air, the combustion air inlet chamber communicating with the combustion air passageway; and a flue gas exhaust chamber above the combustion air inlet chamber and adapted to receive flue gases from the flue and to directly exhaust flue gases, the flue gas exhaust chamber communicating with the flue.

Abstract: An outside balanced flue water heater including a water tank, a jacket surrounding the water tank, a combustion chamber containing a burner positioned adjacent the water tank, a flue extending from the combustion chamber through an upper portion of the water tank, a water inlet and a water outlet connected to the water tank, a substantially airtight exterior shell positioned around the jacket and forming a combustion air passageway between the jacket and the exterior shell, the combustion air passageway communicating with the combustion chamber to supply combustion air from the combustion air passageway to the combustion chamber, a combustion air inlet chamber positioned on top of the water tank and adapted to directly receive outside air, the combustion air inlet chamber communicating with the combustion air passageway, and a flue gas exhaust chamber mounted on top of the combustion air inlet chamber and adapted to receive flue gases from the flue and to directly exhaust flue gases, the flue gas exhaust cham

Abstract: A method of making a foamed-in-place insulated water heater is provided wherein isolation elements are positioned against a tank around the thermostats and spacer elements are positioned against the tank opposite the isolation elements. The water heater jacket is squeezed into an oval shape elongated to accommodate the passage of the jacket over the isolation elements and spacer elements and positioned around the tank and the squeeze released. The thermostats are protected when foam is then introduced into the annular space between the jacket and tank.

Abstract: A water and/or space heater is provided in which water is circulated to prevent the localized overheating or vaporization thereof.
