Abstract (en)
[origin: WO2004074744A1] A combination gas boiler (1; 55) for producing heating water and domestic water has a heating circuit (7) and a domestic circuit (8), a gas burner (9), a heat exchanger (10; 57) located along the domestic circuit (8), and at least one tank (20) located along the domestic circuit (8), downstream from the heat exchanger (10; 57), and connected to the heat exchanger (10; 57) by a domestic recirculating branch (21); a pump (26) is incorporated in the tank (20) for selectively recirculating the domestic water contained in the tank (20) along the recirculating branch (21) to the heat exchanger (10; 57), so as to keep the domestic water in the tank (20) above a given temperature.
