I am pretty new to the pellet stove world and have a question about how much pellets I should stock up. I just picked up a 1993 avalon 900ps for $75. Previous owners said that the auger would not feed pellets. When I got all the old pellets dug out of the hopper I found that it was jamed packed with pellet fines that were never cleaned out and was stuck. After I pulled the auger out and and cleaned it, and reinstalled. It now feeds pellets just fine. I then cleaned out about 2 gallons of ash that were in the stove. Im still working on changing gaskets and painting the stove. I plan on swaping out the old wood stove and putting this in its place. I live in a 1100 sq. Ft. Single story house thats built on a concrete slab with a pretty open floor plan. House seems to be pretty well insulated. On the warmer side of Washington state. With this setup how many pellets do you think I will go through in a winter?
