Abstract (en)
[origin: WO9948713A1] A method and apparatus for improving heating system efficiency. An electronic circuit senses a firing signal from a boiler energy value sensor (26) such as a thermostat or pressuretrol. The circuit prevents the boiler energy value sensor from firing the burner, while the circuit senses an energy value of the outflow line (20) at the boiler (6). The circuit monitors the outflow energy value and records the outflow energy value at a first time of the firing signal. The circuit then continually monitors the outflow energy until it detects an energy drop from the initial outflow energy value. The circuit responds to the energy drop by firing the burner (10). The invention self-adaptively responds to present thermal load, reduces the number of on-off cycles, increases each burner run time while reducing total run time, improves fuel consumption, and reduces air pollution.
