Wood Pellet Boiler

Wood Pellet Boiler Produces Heat from Waste Sawdust

Heat for the Harris Center is supplied by our wood pellet boiler. This is the first wood pellet boiler installed in a public building in New Hampshire. This is a multi-heat variable output boiler, maximum rated at 146,700 BTU. Wood pellets burned in the boiler are made only from sawdust, a recycled waste product of our renewable forest industry.

The pellet boiler burns at 90% efficiency. We burn an average of 23,000 lbs. of pellets a year to heat our 10,000 square foot building. The cost has been about $1700 a year. If we had heated the building with #2 fuel oil, at a current price of $2.29 a gallon, our annual heating cost would have been $4220 a year. Burning the pellets for one year resulted in 126 lbs. of ash that fit nicely into a 29 gallon trash can.

The wood pellets are bought in bulk and stored in an external 18’ high silo. A flexible auger delivers those pellets to the boiler’s 12 cubic foot fuel hopper automatically as needed.
