Ordered a PE Vista insert yesterday after months of researching what might be just right for our home. The info here has been super, and I thank everyone for all their wisdom. After a $300 gas bill in December, we decided we had to do something. We are blessed with a bountiful 5 acres - 4 acres of mixed hardwood, mostly ash, maple and cherry, a nice clean stream that runs all year round, and a very productive 1/2 acre garden that provides us with all our fruit and vegetables. Getting more heat from our fireplace is going to make things that much better, since the wife and I are getting a bit older and the cold seems to get a little harder to take. Again, thanks to everyone for all the things I have learned here. Plan to stick around and post pictures after the install is done.
