If you’re considering using wood pellets or you have just installed a pellet stove you may be asking yourself this question. Of course there is no one easy answer, because you have to account for the size and shape of the house, how well insulated it is, and the efficiency of your pellet stove, but we did some research and found a few numbers to help you out.
1 ton of wood pellets = 120 gallons of heating oil = 170 gallons of propane
This is based on 80% efficiency of both, the oil heater and the pellet stove.
On average, people use 4-5 ton of pellets for a 2000-2500 square foot area per season with the wood pellets being the only heat source, and about 3 ton for a 1500 square foot space.
When using pellets as a supplemental heat source most people will end up going through about a ton or a ton and a half of pellets for the season.
