Agreed - I installed a wood pellet stove this past fall and it's been an absolute godsend. Total fuel costs so far this year are about $400 on pellets and $200 on fuel oil (mostly to keep making domestic HW for showers, dishwashing and such). It's also a safety net that'll kick on at 60 degrees if the pellet stove goes out when I'm away from home or whatever.
Last year I spent over $1,500 on heating oil. F*CK OIL! I'm never going back. Next step is to finish plumbing up my electric HW heaters (one 40 gallon, one "instant" tankless) and tell the oil companies to stick it where the sun don't shine for good. At that point the oil fired boiler will be kept around for emergency backup use only - permanently.
I have a wood-burning stove in my shop and am considering one for the basement since I have a virtually limitless supply of wood to burn (and it's renewable) out back, I just hate dragging that stuff into the house even if it is the basement. If I do I bet I can hit 77 degrees year round with no oil burning and little pellet use.
Insulation helps too.
