Abstract (en)
[origin: US4373472A] A water heater has a closed container of approximately circular cross-section, a housing surrounding at least a lower part of the water container, the housing being closed by a base and forming, with the base of the water container, a gas-tight combustion chamber, a lower induction aperture for fresh air, an upper extraction aperture for waste gases, and passages through the water container for inlet and outlet pipes. The improvement is that an annular space connected with the combustion chamber is formed between the housing and the water container. The waste gas extraction aperture and the fresh air induction aperture are located in the housing. One or two box-shaped corner sections, for one or both apertures, adjoin the curved housing and, by means of their side walls, convert the housing in the vicinity of the corner sections into a rectangular shape. A connecting branch to link up with a through-flow unit in the outer wall is provided in one side wall.
