Little history, bought a house 6.5 years ago that came with a Whitfield pellet stove, main source of heat was oil At first I used the pellet stove as a novelty since I didn't know much about them, oil was also $1.85 a gallon back then. I was also hesitant to use the pellet stove when no one was home or we were sleeping. As oil prices rose more than double over the years I started to put more faith in the pellet stove. The stove will keep 75% of my house heated beause of my open floor plan and stairs leading up to the second floor, for the last 2 years I burn 5pm to 5am every weekday, then from Friday 5pm straight till Monday 8am. With this years cold weather I am on pace for my biggest year so far, looking at about 4 ton as I have already burned 125 bags. With the pellet stove I would still burn oil to keep the other 25% of my house warm and for hot water. On the coldest months I would only burn 90 gallons of oil when I would hear of people using 200+ gallons a month. I've since converted to natural gas for the rest of my heat, hot water, stove, and now a gas dryer. 5 week gas bill was $150 plus 25 bags of pellets. The pellet stove was saving me a good amount of money compared to the oil and now with the gas I cut what was the oil expense in less than half. I've been burning Green Supreme's @ $209 a ton all year, heat has been great and ash level much lower than last year.
