I've had a Lennox/Whitfield pellet stove in my basement/garae now for about four years. It's been a great stove and did a very good job considering it was only 36K BTU/Hour unit. I thought it was too fancy to be in a garage I had all the gold trim on it and it was a bay window model. I sold it and bought a Breckwell Big E which is a more utilitarian type of no-frills job. I picked the Breckwell up on ebay for $1400.00 shipped (my local dealer wants $1699.00 plus sales tax). The unit arrived safely from the middle of the country in two days via Old Dominion curb side delivery (thank the lord for a tractor with a front end loader, it weighs in at 300+ lbs). I also ordered a radio frequency wireless remote for the new stove, it's on back order and should be shipping soon.
So the new stove is listed at 55-60K BTU and up to 2200 square feet. I have been running it on heat setting #3 (it goes to #5) for the past few days and it's keeping the entire house so much warmer than the last stove and it doesn't seem to be using any more fuel to do so. About a bag a day on #3.
It went down to 13 degrees last night, I have three garage doors in my garage all are insulated Wayne Dalton's but still, the garage was 70 degrees all night on setting #3! I ran the thing on setting #5 for 10-15 minutes and it was 80 degrees, I turned it back down!
So if any of you are looking at buying a wood pellet stove, check out the Breckwell's, they are auto ignight stoves so when coupled with a thermostat (either thier own RF wireless or a regular 100-200 Millivolt Honeywell) they will shut off at the cutoff temp and turn back on when the temp falls.
That is the version I went with, it's the utility furnace version, no shiny frilly stuff on this one.. You can get the home heater version with nickel or gold trim, removable ash pan etc.. For the garage, not needed or wanted.
