We are going to be building a house soon and we wanted a wood burning fireplace... my brother ended up putting in a buck stove insert into his fireplace and I really like how it has worked for him. But with building a new house I figured I would do it right from the start instead of retrofitting down the road. It is not my intent to use my fireplace for the majority of my heat but when I do use it, I actually want to get something out of it. I stopped by a local fireplace dealer and he suggested the Kozy Heat Z42. Any opinions on the unit? Or any other suggestions. I don't have a specific budget but I don't want to spend to much either.
