I just started researching wood burning inserts and became very overwhelmed. I am not very knowledgeable on fireplace, since I was born and raised in the south. I am looking for an insert that not only looks elegent but provides heat. We have 3700 SF open floor plan house that we would like to heat as much as possible ( I know the insert will not heat the whole house, but could help cut some of our heating cost). I like the models that are flush mount and have large viewing windows like the Wittus H530, Rais 600, and the Morso 5660. I have attached a worksheet with our dimensions and a picture of our fireplace. Does anyone have any experience with these models that could provide some information or guidance? Thanks
