This is my first post here. I've been looking through the threads because I got a second hand insert (Silent Flame) and it just isn't cutting it. I've got a nice big fireplace that I set this in and put the skirt around it. No liner, nothing. It doesn't really keep a hot fire in it (probably because there's nothing on top to keep it warm). So I started looking around here to see if buying a new wood burner (epa approved non cat) would let me cut back on the amount of wood I burn and throw out much more heat. The insert is very small and will only take 13" logs so it's pretty much useless. I realize that I probably tried to kill my family buy putting that insert in without a liner. I realize that NOW! We don't get much cold weather, but wife wants the house warm and I think heating with wood is much cheaper than natural gas. Our house is 50 years old and quite drafty and the central heat unit is 15+ years old so it's not a high efficiency unit. I really don't have a ton of money to spend on a new insert because the Liner will be +-$400 or so. I was hoping for a Craig's list miracle or finding something around $500-800. My dad has an older fisher stove and it pretty much heats his 1700 sqft house and keeps a fire through the night. I was hoping for those kind of results when I got this insert, but it's barely better than just a plain open fire. Here's my question. Would my silent flame work properly and burn nice and warm actually keeping a fire if I put a transition on it and relined with SS liner + block off plate? Or would I be much more pleased with a newer model that's more efficient? Until then... no more fires
