I just started researching pellet stoves and I narrowed it down to St. Croix Afton Bay or Harman Advance. I like the way these stove look and I know they are of good quality, but are they to much stove for my needs. I have a 900 square foot open room with cath. ceilings and it sits above a garage. I only need it to heat this one room. Please help me make a smart buy.
