  • Seven Telltale Signs Your Boiler Needs To Be Replaced

    Mar 15, 2016 · In the case of an oil-fired boiler, there may be soot residue. Soot can act as an insulator which cuts down on the efficiency of the heat transfer between combustion gas and steam or hot water generation. When inspecting your boiler, remember to look for any signs of corrosion, overheating, or erosion, as well as any leaks from the boiler or Learn More
