ABSTRACT:
A submersible chamber water heater having improved efficiency. The water heater includes a tubular member that is mounted in an opening in the tank and defines a combustion chamber. A fuel-air mixture is supplied to a burner located within the combustion chamber and the waste gases of combustion are conducted from the combustion chamber into a series of heat exchanger tubes which are positioned beneath the combustion chamber and are then discharged to a flue. A conduit extends through the combustion chamber and the ends of the conduit communicate with the interior of the tank. One end of the conduit is at a higher level than the other, so that water flows by convection through the conduit to increase the efficiency of the heating operation.
