Your boiler heats your home during the winter to keep it warm and comfortable inside. The water in your boiler system is heated with the heat exchanger, a number of tubes in the firebox, which the water is pumped through. The tubes are cooper, steel, cast iron, or other alloys and they go through a lot of abuse to heat the water to warm your home. Over time they get clogged with soot and may not heat as well. Cleaning the soot from the heat exchangers in your boiler will correct the problem.
