Abstract (en)
[origin: US4695052A] A hot water heating system powered by a gas burner uses the output signal of a heat consumption meter measuring the amount of heat flowing to heating radiators for controlling the heat capacity or heating power of the burner. A control signal dependent on the demand of heat is fed to a solenoid operator of a servopressure regulator and the required amount of air for achieving optimum combustion is supplied via an air control valve which receives its input signal from an oxygen or carbon dioxide sensor in a burner stack.
