Hey all. New to the site and forums. currently have the medium sized regency model from the 1980's and desperate need of replacement. The unit is used as our primary heat source all season long as our house is run on all electric. That being said, we are currently looking at the new Green Mountain 60 by Hearthstone. it was suggested by a local dealer. We like the look bit is it tough and a good unit to run all day every day and through the evenings? We need it to heat about 2000 sq ft daily. Anyone have experience with the new units? Thanks!
