Have you tried a pellet stove? We love ours (here in MA)
I have a Jotul woodstove. My regret is not buying a bigger one. I have the model 3C. It is a great stove but does not have a long enough burn time.
I went to the homeshow in Manchester this past weekend.
I saw a furance made by Lesiure Line that burns either oil or anthrasite coal. You can switch between the two. It runs about 85% efficient on oil and 90% on coal. The hopper holds about 2-3 days worth of coal. It was about $4500 plus installation. Based on oil’s current price, I figure it would pay off in about 5-6 years.
What brand/model pellet stove do you have ?
Where do you store the pellets ?
