Heat recovery from oil fired boiler | Terry Love Plumbing

May 20, 2015 · By extracting heat from an oil burner exhaust stream you will be condensing highly corrosive acidic liquids out of the exhaust onto your heat exchanger, and possibly dribbling into the boiler itself. The very reason for the air dilution prior to the flue is to lower the dew point of the exhaust gas mixture to prevent condensation in the flue, which can destroy a masonry chimney in very few years.
