Abstract (en)
[origin: EP0781965A1] The hot water system includes a device (40) measuring the flow (Qecs) of sanitary hot water in the circuit (11,14), and a further device (30) measuring the temperature (Ts) of this water at the output of the heat exchanger (13). A control system (100) controls the modulation valve (20) in response to the detected temperature and a reference temperature (Tc). A module (103) providing proportional control action adjusts the valve (Qecs) adjusting the pulsed flow of gas to the burner, thus providing a continuously adjusted and controlled burner output in response to the measured conditions. The proportional action operates according to a control formula taking account of the flow and temperature measurements, and the known characteristics of the boiler.
