Wet1 said:1000 gal of oil is about 139,000,000 btu. Four tons of pellets will only produce about 67,000,000 btu... You do the math.
Some people get by with using fewer btu with a space heater. This is typically because people tend to centralize around the space heater and other areas of the house tend to be cooler than they would otherwise be with central heating. Space heaters can also be a little more efficient when compared to central heating, but we aren't talking 2x as much!
Interesting:
So 9 ton would be the equivalent to my 1000 gallons. With that, Pellets are about 2100 vs. 3500 of Oil (assuming 3.50/g) That pays for my stove in year 1. In all honesty, every situation is different. For example, i installed new Low-e windows throughout my first floor, i insulated 2 rooms, and i suspended the ceiling. And I most certainly will be eliminating drafts before the winter. The one good thing that came out of the sudden spike in crude is now i have an alternative fuel, along with a much more energy efficient home.
Now all i need to work on is to combat the 43% rise in Electricity costs come this November.
