Abstract (en)
The device has a heat exchanger (3) that is made of non-annealed copper and yellow metal. The heat exchanger comprises a heat reception part (9) that is placed in a combustion chamber (1) at proximity of a gas burner (2). The exchanger forms a grid that is determined by a set of flat tubes (7) that are parallel with each other. A closed water circuit (5) is established through the heat exchanger and a pump (6) circulating the water in the closed circuit.
