So I am currently using an Englander stand-alone unit and love that thing. I live in a double wide mobile home with a large addition built on to the back of the house. I am going to be removing the standalone unit and installing an insert in the main part of the house and build a mantle/faux rock wall, etc. My wife and I have been looking online at various inserts and really like the looks of the Quadra fire castile and the Mount Vernon. However, reading online it seems that there are so many problems with these units that I'm not sure if I want to fool with quadra fire. Seems most of the complaints are about pellets backing up and catching the whole hopper on fire, clinking and other loud noises. Also, my local prices in Kentucky are $3100 for the castile and $4500 for the Mt. Vernon. My house is roughly 1900sq. ft. I never have to run the englander much to heat the whole house. Usually run the feed on a 3 out of 9 and burn for nearly 24 hours with a full bin. Looking for some buying tips on a safe, reliable insert with the aesthetics of the castile and the Mt. Vernon.
