I live in an "L" shaped ranch house that is approximately 1800 sq. ft. I currently heat with a breckwell big E pellet stove and it is just not getting the job done in heating the upstairs. I have a full unfinished basement and that is where the stove is located. I know it is not the ideal setup so I have been considering a coal stoker to replace it. I am currently looking at a leisure line hyfire II, alaska channing, and a keystoker 90 or 105. I am looking for some opinions on the stoves I listed as well as any other recommendations that would work well for my application. How many BTU's should I be looking for in a new stove to heat the house? There is ductwork within 8 feet of the stove location so there is the potential to add an accessory blower kit to a new stove and tie it into the ductwork but I am not exactly sure which duct I need to tie it into. Thanks for any help you can provide.
