I have two of these, really great stoves and I have no regrets. Saved my a** this last winter (that will not go away - frost tonight so perhaps it is still this winter). How are you going to duct this into the propane system? This stoves stellar heat transfer characteristics need a little care to maximize. Remember we love pics and we may be able to give you some extra ideas. How well are you insulated? Basement install, I assume? Where in upstate? To quote a venerable poster I promise we won't steal ya. Upstate NY winters do vary from merely horrible to absolutely ghastly. Don't forget you may get help here on cheap(er) coal supplies. Powervent installs are generally not hard, do you need to spend the $6000. El clutso here installed mine in under one hour (love powervents). I installed my stove soup to nuts in under three hours whilst consuming three mugs of my winter warmer and I'm no Bob Vila. It even looked good the following day.
