A direct contact water heating system employs a vertical water tower having a sidewall with a combustion inlet opening spaced above the tower lower end. A generally horizontal combustion chamber has a sidewall in communication with the tower combustion inlet and an end wall spaced from the water tower. A burner has a combustion outlet in communication with an opening in the end wall, the combustion chamber end wall having an annular area surrounding the burner combustion outlet. Products of combustion flow from the burner, through the combustion chamber into the water tower through the combustion inlet opening. A shell has an inner end attached to the water tower sidewall. A sidewall portion of the shell surrounds the combustion chamber sidewall and an annular portion is spaced exteriorly of the annular area of the combustion chamber end wall. An interior surface of the outer shell and an exterior surface of the combustion chamber form a closed envelope having a water inlet and a water outlet. A flow system passes water through the closed envelope to cool the combustion chamber. In a preferred embodiment the combustion chamber end wall and the shell annular portion are both frustums to provide more rigid support of the burner.
