Hi Everyone, I’m new to the forum and I live in PA where we get some cold temperatures. My home is a split level that was built in 1970 and has a fireplace with an old wood-burning insert in the family room which is the lowest level of the house. With the blower I’m able to heat the entire house but the lower level gets very hot and the top floor is always a bit chilly. First, I am looking for a good catalytic insert with a blower that can give long burn times. I’m also interested in learning if I can connect it to my air handler so I can move the heat more evenly throughout the house. My fireplace backs up to my garage and there are a couple of holes in the block that could potentially (IMHO) be used for connecting to my duct work in the garage ceiling. If I could do this it would give me an improved alternative heating method on really cold days when my heat pump can’t keep up. Any and all input is appreciated. Thanks everyone.
