I am currently heating with a 50,000btu corn/pellet stove, 2000sq ft, stove will keep up even with 0 degree temps and wind. My question to the owners of these units, why did you, and would you again purchase one of these units? What is the life expectency of these units, cost? They seem to have simular btu ratings, and cleaning schedule. The reason for the potential change is I would like to get the fire out of the house, and the kids are growing so an endless supply of cheap hot water might be needed.
