ABSTRACT:
A water heater is shown having a closed tank with an opening for receiving a combustion chamber, the interior of the tank normally containing water under pressure. A combustion chamber is located within the tank interior and includes a body portion having an open end adjacent the tank opening into which combustible fuel is introduced and ignited in the presence of air to create products of combustion. A flue collector is mounted on the exterior of the closed tank and has an annular chamber surrounding a flue opening for receiving the products of combustion for exhaustion to the atmosphere. An outer wall portion closes one end of the flue opening to provide a closed compartment within the collector which can be pressurized by an external blower. An inner wall portion of the collector has an opening which communicates with the combustion chamber. A fuel supply conduit carries a pressure plate and electrodes which provide controlled ignition of the fuel and air mixture within the opening in the inner wall portion to provide heat to the combustion chamber of the closed tank.
