Hello All - I am glad I found this forum to get real world advise and answers from real world users. We just had a new Mt.Vernon AE pellet stove insert installed. I have had several evenings to "play" with the stove and the thermostat. To this point I am somewhat disappointed in the performance. Several people I talked with (including the company I purchased from and his installers) told us how it would pretty much "run us out" of our living room because of the heat output. As of this point - and having it run all night on high or medium high or leaving the thermostat set at about 75 degrees - I have yet to get the temp of the room over about 68 degrees. Here is some background - 12 year old stick built home, 2x6 exterior walls, good insulation. The living room, kitchen and dining area are one large, open concept room with vaulted ceilings. Total square footage is about 1500 - 1700 sq. ft. We have a ceiling fan running in the main living room area and it is located just out front and above the stove. I have had the fan running in both directions and at various speeds without any difference in temp. I have increased the flame from the 0 setting up to +4 and do not notice any heat output difference. I am just curious if this large of an area with vaulted (about 18 feet at its highest point) ceilings may be too large of an area to expect a temp of 70 to 75 degrees. Any suggestions or information would be greatly appreciated. I am burning premium hardwood pellets (Easy Heat). The company I purchased the stove from and the pellets (Schlemmer Brothers in Wabash, In - GREAT, GREAT, GREAT group of people and very good to do business with) just started using these pellets and even they say they are probably not the best on the market. I am going to try a different brand when Schlemmer Bros. gets a new shipment to see if this helps. Thank you in advance for any help or ideas that can be offered.
