in THE MAIN WALL
My family thinks I have a very strange hobby but I just like to spend time in front of the boiler. (maybe I'm in the wrong profession) Anyway I always find myself wondering which zone is calling and now I've got an easy way to see at a glance. 24 volt LEDs fit nicely. I remember seeing Hotrod doing something similar on circulators. But I think I've run out of stuff to do on the system. I've repiped it pumping away, and replaced the indirect. If gas keeps going up yanking the boiler and replacing that with a modulating/condensing unit will be next.
