Hello all, what a wonder forum...... Heres my 1st post.... Im interested in a room heater approx 400 to 500 square feet.. Im wondering if anyone out there has a aspen and would give me some feedback on it.. How long is the burn? are you happy with performance of the stove? and so on.. Had a defiant encore years ago and loved it. Now looking for much smaller heater. also any other suggestions besides the Aspen.. Thanks in advance Marty
