The gas water heater consists of a blower 1, a mixing arrangement 2, a gas burner 3, a heat exchanger 4 and a flue gas heat exchanger 5. The gas burner 3 works as a superstoichiometrically mixing burner and has on the rear side a cold burner plate 9 with a number of mixture flowthrough openings 10. The heat exchanger 4 extends between two chambers 6, 7 which are located next to one another and are flowed through in opposite directions by flue gas. The condensation heat exchanger 5 works in counterflow and consists of star-shaped profiles which are flowed through in the middle by heating water and which are arranged vertically. The flue gas heat exchanger 5 and the mixing arrangement 2 run parallel to one another. <IMAGE> |
