Thanks in advance for your time and responses. This will be my primary heat, atleast for this winter. It is an app 1100-1200 sq foot home with an open floor plan on the first floor with 2 bedrooms upst. Stove to be on first floor. I live in Deleware in a 1927 built home. Some improvements have been made in insulation and windows etc. I have concerns about the rated btu's even though it says up to 2000 or 2200 sg ft. Also wondering if it has an undersized blower. Only rated for 140 cfm. Most it seems rated to heat an area this large have a blower rated up to 240-300 cfm. I understand that it is better for a unit to run at a higher setting than oversize it and have it run on low all day. Also would the logset effect rating or performance at all? Any other thoughts or suggestions would be appreciated. I am hoping to purchase from AMFMENERGY. Thanks again in advance.
