Hi Guys. I’m new to the forum and wood inserts. I have a very large and pretty open home about 4,000 Sq Ft. The home has a fireplace in the Great Room which is 27x25 with 16ft vaulted ceilings. Off of the Great room i have my foyer with 22ft ceilings and that goes right up to the bedrooms. Also off the Great Room There are 2 double doors going into an open dining room living room and there are 2 large openings into the kitchen. So like I said its a really open floor plan Im looking for a Insert for my fireplace that is going to allow me to burn the least amount of home heating oil. Looking at a few Inserts i have stumbled across the Osburn 2400. With its large firebox and 100,000 btu rating most other inserts don’t compare. I can get this unit for around 2,050 plus install. I have read many posts about this unit vs others and just don’t understand how the others can compare to the stats of this monster. Can someone please help me out and or give me a recommendation. My home is very well insulated and all 2x6 construction built in 1991 so its not an old home. I just purchased this home about 4 months ago and can see burning about 1500 gal of oil in a year so thats why im looking for some help. Thanks in advance.
