I have burned two tons of Somersets so far. I pulled the baffles off last night and pretty much everything was packed with ash build up. I cleaned the heat exchanger tubes and everything else out. I check temps pretty regularly with a infrared temp gun. After cleaning my exhaust temp went way up the room temp lowered 5 degrees from its normal temp. The exhaust temps usually were around 130 + or -. Now they are around 150+ or -. Is it possible that the ash was holding heat in around the baffles transferring more heat to the room instead of out the exhaust? It seems I am losing more heat out the exhaust now. Exhaust blower is definately happier. Flame height is much shorter on high. I can change that by adjusting the pellet feed but then I'll be burning more pellets. I'm back to considering fabbing up a way to put a heat exhchanger in the chimney pipe.
