I recently made some changes to my old tarm 502 boiler. Big difference in performance. Tinkering pays off. First of all, every yr gets better and better, one improvement at a time. Better chimney last yr increased draft. New door (old one was badly cracked and leaky). Those are the big changes. Most recently I added insulation to the supply and return pipes, about 20 ft each way. This alone made a huge difference. I now have a deep bed of coals after a long burn (6 or 8 hrs) and never have to re-lite). I cost about 70 bux for the pipe insulation. I think this is the most bang ofr the buck. Less wood consumption. I also added more insulation to the house last yr, mostly under, over and around three big bumped out bay windows. It justs keeps getting better and better yr after yr. INSULATE, INSULATE AND INSULATE. It works great.
P.S. As a newb many yrs ago I did not always listen so well, I now wish I listened more and sooner.
