Howdy - We are still new to the pellet business, but really loving it. We got a Greenfire (Enviro) insert last fall and LOVED it. We are thinking of adding a free-standing unit to a porch/three season room on the other side of the house. Right now, its an un-insulated 3-season room, but we'd like to finish it off. Its got a nice brick floor, so we were thinking that maybe we could start by adding a free standing stove. The room is about 25'x20'. There are crappy sliding windows now, but its going to be a slow process. It opens onto our kitchen which is largely unheated too, both of these rooms are as far from the other stove as they can get. We would only run the stove in that room during the day, when we are using that space, so I was wondering if we could get away with a used stove. We paid $3300 installed for the insert, and I don't know that we are able to put that much in to this. I am pretty handy, but not well versed in stoves yet. SO, i THOUGHT maybe somebody out there might have an opinion... anybody? You guys have opinions on this kind of stuff right? What should i be looking for?
