Hi everyone! Great website,except very addicting-at least my wife thinks so.I have made the decision to order a new Progress Hybrid,largely based on comments on this site and after talking to Woodstock--seems like they are great folks and very helpful.I will be putting the stove in a house I am building in the mtns. of Idaho--approx.4800' elev.I am trying to decide between single wall and double wall black pipe from stove to 9' flat ceiling.The stove will be hooked to outside air for combustion(when Woodstock makes the kit available) All exterior walls of the house are ICF (insulated concrete form) so it will be very tight-hence the outside air requirement.What I am wondering is since I will only have about 6' of black pipe from stove to ceiling,then approx.12' on HT S/S chimmney through attic and roof,Is there any reason to use dbl wall black?The house has no plumbing or electrical yet and I am more excited about the new wood stove
