I want to replace my 20 year old Breckwell P24i . A local dealer has the Harman Accentra, Quadra fire Trekker, and Regancy GCI 60 on sale. Any recommendations? The insert is in my family room which has 18’ ceilings and I have about 3200 sq ft. to heat. My Breckwell still works but it’s time for an upgrade.
