Abstract

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.

Description

technical field [0001] The invention relates to a gas boiler. [0002] More specifically, the present invention relates to a wall-mounted combined gas boiler, that is, a wall-mounted boiler for supplying hot water and domestic hot water to a heating circuit, and the hot water supplied to the heating circuit is hereinafter referred to as heating water—— and domestic hot water. Background technique [0003] A wall-mounted combination gas boiler generally includes a heating circuit, along which hot heating water is conducted; and a domestic circuit, along which domestic water is conducted. The heating circuit is connected to an external heating circuit equipped with a radiator; one end of the domestic circuit is connected to the water main or other domestic water source, and the other end is connected to a circuit for distributing hot domestic water to one or more consumer equipment superior. The wall-mounted combined gas boiler also includes a gas device and at least one bi...
