Cordwood Boilers

Cordwood boilers have been in use for many years, and they will have a place in the heating market in the future as well. They make sense when cheap fuel is necessary, or where cordwood is the only possibility.

These boilers use cordwood instead of wood pellets. Wood is fed to the boiler once or twice a day during the heating season. The boiler is fired very hot to get the best efficiency by minimizing unburned gasses, and soot and creosote buildup from cooler fires. Because the boiler is fired hot and relatively quickly, the heat is moved to a holding tank, where it is drawn off throughout the day as needed.
