I am with Wilbert I am hooked up to propane and last year we paid $248.00 per month used 975 gal. We did the math and bought a pellet stove in September and started burning pellets 10/1/08 as of tonight were on the 10th bag. We will be getting snow and rain by Wed. and temps will drop to low 20's. Propane tank is topped off a cost of $579.00 for 190 gallons. I am hoping to keep the propane furnace off this winter or on very little. Even at a bag a day I will still be ahead on cost of propane and stove will pay back in a couple of years.
