Hi,I'm new to Hearth.com. We want to ad an insert to our 1100 sq ft ranch. I like the Lopi and Avalon inserts. The local Lopi dealer says The Answer will heat our home. The fireplace is located on an inside wall right in the center of the house. The house was built in the 60's and has 6" insulation in the attic. I have a cealing hight of 7'7" and there is a 9ft picture window on the wall opposite the fireplace. It's a little drafty near the window. I don't plan on heating 24/7. Just set thermostat at 55-60 and run insert when we are home. Will the answer do the job or should we move up to the revere? We have an old boiler and wife doesn't want to replace it. It works fine but,gas bills are expensive. I'm also thinking of the Avalon Rainier. A little smaller than the Revere. Any advice would be much appreciated. Thank you. I forgot to mention we live in Ma. Thanks again.
