I currently have a Quadra Fire Castile Pellet Insert that is getting replaced through warranty due to cracked heat exchanger tubes. The repair man suggested that we replace it with the Classic Bay 1200i because it would be more efficient for our large open living area. Our entire house is approx 2000 sf. I've read bad reviews on the 1200i but I've already lived through some issues with my Castile. Besides the cracked heat exchanger tube my biggest complaint was the ratting and loud blower of the Castile. We have replaced the pellet auger, burn pot and some circuit board. I was wondering if anyone has any suggestions/recommendations? Thanks for your help.
