Abstract
The water heater has an upright water tank (), an exhaust flue () extending through the water tank, a combustion chamber () arranged under the water tank, an atmospheric gas burner () 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 () with a pressure drop less than 5 to up to 45 Pa. The combustion chamber () is provided with an opening (), which is not sealed, but enclosed in a flame-blocking manner. The gas burner () is attached to a wall section (), which is mounted releasably on the: combustion chamber wall (W) over opening () 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.
