I was up on my chimney putting Crown Coat on the top and was really disappointed to see how hot the vent cap was on my liner coming from my Castile insert. Looks like I use a lot of my pellets to keep that 17 feet of 3" flex pipe nice and warm. At 75% efficiency, we use 500 pounds of pellets out of every ton just to heat the great outdoors. What a waste! When you look at the path that the hot air takes through the stove you can see why the efficiency is so poor. It sure isn't well thought out. One pass across nice, smooth pipes (laminar flow) and out the exhaust. If my stoves weren't new, I'd get in there on the off season and weld some fins on the pipes where the scrapers don't go to break up the flow and make it tumble as well as present more surface area to absorb heat. Those pipes really should be corrugated or finned and there should be a lot more smaller ones for more surface area. Piss poor design IMHO.
Has anyone done anything to address this situation?
