I believe I am ready to make the change from hand fired to a stoker stove. Currently running a Harman Mark II sitting in front of a fireplace in living room. My house is between 2000 - 2200 sq ft. Works well 95% of the time, only on the coldest days I wish it were a little bigger. As some may know from a previous post I have been searching for a used 85k btu alaska hearth stove. I have not had any luck yet. I have come across a nice Keystoker Hearth 90. I like the look of the alaska a little better but I am ok with the Keystoker. Looks in good shape, the extra 5k btu could be useful, and from what I read they may transfer heat better as the fan blows up the back and across the top vs alaska just blowing across the top. My only concern is about the hopper size. The keystoker only has a 50lb hopper. One main reason for wanting to change is to be able to go away for 2 - 3 days on a weekend and keep the stove going the whole time. How long can I expect a full hopper to last? If this stove had a 75 or 100 lb hopper I think I would have already bought it.
