A water heater/boiler design is shown having a tank with a submergible, pressurized combustion chamber so that all of the heating surfaces of the combustion chamber are submerged under water. The products of combustion are routed from the submerged combustion chamber to a secondary heat exchanger having heat exchange tubes which are also submerged in the tank. A forced draft burner is used to heat the combustion chamber and the burner inlet air is preheated by passing the inlet air over portions of the secondary heat exchanger located on the exterior of the tank.
