Hello, I have been visiting the site as a guest for a while now and my County Flame BBF fireplace insert is now up and running. Thanks to all that take the time post their experiences and knowledge. There is a wealth of info here and it has been very helpful to me. The BBF is not mentioned much so maybe I can post some results over the coming winter months to give others some feedback. It is the largest model made by Country Flame and is a catalytic stove. I bought it locally used out of a shopper for a very good price. It was barely used by the previous owner and is in really nice shape. I did have to replace the combustor which is quite pricey compared to other stoves. It is a well built and heavy unit(600lbs.) that I installed myself. I will be heating a 2300 sq ft ranch home that has a fairly open concept design. Hopefully, it will be enough to heat our house through the cold Wisconsin winters.(if not I have a line on a free Yukon Jack add on furnace to use for back up) So far we have had several nights in the mid 20's and days in the low 40's and the house stayed above 70 on three small to medium loads of elm with the blower on medium. I do know for sure it has not consumed nearly as much wood as the Yukon Big Jack in my old house(which I loved) but it is not an apples to apples comparison yet either. The true test will come when the needle dips below freezing and don't come back up for a good long time. Hoping for the best.
