Hello all - new one to the forum. My house is a 2 level ranch with about 1400 sq ft each level. The house is an L shape with a big brick fireplace at the very end of one of the L "legs". The firebox is 28" high by 47" wide. I am planning to install a wood burning insert but was wondering/concern about pushing warm air to the other end of the house. I have all the duct work for my central AC in the attic. Is there any way to use it to get the warm air everywhere ? PS: To simplify the issue, the lower level of the house is not hooked up to the AC and can be disregarded at this time. Thanks all.
