Indirect coil descaling, follow-up to old post
Thanks to those who gave me advice regarding the descaling of my SS-45. It took me a while to get around to this, but I thought the results were worth posting. I shocked the coil as Ironman suggested. I flushed the tank with vinegar and water after as well. The clear water in the first pic is from the initial draining of the tank. The muck that came out of this thing after shocking the coil was, well, pretty shocking! ( to me at least ). This completely solved a short cycling issue during calls for DWH.
Thanks again, J
