摘要

Automatic regulation system for gas boilers with double water circuit, each of whose circuits comprises a temperature and/or circulation or water passage detector, and coils heated by a common burner, essentially characterized by the fact that the said burner is connected to the gas inlet of the apparatus by means of a circuit comprising a first valve, modulated between a minimum flow rate, corresponding to a reduced gas consumption for the two circuits, and a maximum flow rate, in series with two derived circuits that they open together in the burner and each of them comprises an all-or-nothing valve, the two derived valves being subordinated to the excitation of respective water circuits, while the first valve is subordinate to the temperature of the circuit in operation .
