Abstract: The water heating apparatus has an upright cylindrical thermally insulated storage tank, an axially extending exhaust gas pipe passing centrally through the storage tank and a combustion chamber under the storage tank. An atmospheric gas burner, which has a complete premixing fuel gas/air supply system, is arranged within the combustion chamber. The exhaust gas pipe has a section extending within the combustion chamber, which preferably extends towards the bottom of the combustion chamber and has an end located a few centimeters from the bottom, so that the combustion gases have a longer dwell time in the combustion chamber and the exhaust gas pipe in order to improve heating efficiency.

Abstract: The water heater has an upright water tank (1), an exhaust flue (3) extending through the water tank, a combustion chamber (2) arranged under the water tank, an atmospheric gas burner (5) in the combustion chamber and a complete pre-mixing gas/air supply system with outside gas and air intakes. The gas burner has a burner mat (7) with a pressure drop less than 5 to up to 45 Pa. The combustion chamber (2) is provided with an opening (2b), which is not sealed, but enclosed in a flame-blocking manner. The gas burner (5) is attached to a wall section (2a), which is mounted releasably on the: combustion chamber wall (W) over opening (2b) so that a gap of predetermined width is formed between the wall section and wall (W), which prevents backfire of flames into the surroundings but admits secondary air.

Abstract: The gas-fired heater, especially a water heater, has an atmospheric gas burner (5) arranged within a nearly or completely closed combustion chamber (2) and associated with a premixing gas/air supply system (8) with a fuel gas feed nozzle (10). In order to avoid oscillations, which lead to sound waves and combustion instabilities, an oscillation-damping air supply chamber (11, 11′, 11″) is connected to the entrance (8a) of the gas/air supply system (8) for combustion air, within which the fuel gas feed nozzle is arranged. The air supply chamber (11, 11′, 11″) is provided with at least one air entrance (12, 12′, 12″). The air supply chamber can be box-like, duct-like embracing or extending around the combustion chamber or it can be a pipe with different diameter pipe sections.
