Anyone have any feedback on these boilers? They seems like a very simple design that works off a dampener and no blower. However I can't find any real reviews or testimonies on them in the ole Google. I know the classic design not a gasser. I've been second guessing paying $11,500 for a unit as I'm not rich by any means and tired of the $3k yearly propane bill. My wood supply is pretty much endless as the tree companies local to me basically beg you to take the wood from them. I know you burn a hole lot more with a classic stove vs the gasser but is it really that significantly less that it outweighs the extra $6k for a gasser and dozen more parts to break or malfunction. Maybe I'm just over thinking but man I can't get it out of my head.
