I have an oil-fired steam boiler, with a hot water coil. The flow seems reduced thru the coil, which leads me to think it needs de-mineralizing or cleaning, but I have never done that. When I shut off the boiler for the summer, switching to my propane demand heater, I plan to try to clean it. Any help?? The output is easy to remove, but the feed line is soldered in place...
