I ran across the system ......
I have heard about this system but never seen one. The house is a here in Dover built in the early 50's a coal boiler, converted to oil, converted to gas. Runs great. The soft copper is embedded in the walls. No leaks. It has a form of outdoor reset. Surprising the boiler today was running at about 120F.... No condensing. I hope the pix come out straight.
