Welcome! Here are some tips for using this forum.
Anyone have any idea what the maximum sustained temperature we can maintain in a SSU 119 dual coil tank. Manual doesn't say and supplier is indicating just about what ever we want.
Been having a problem with tanks not holding up and looking for a cure, talking about tanks not lasting even a year . Have had 3 tanks let go over a 4 year span. There are two tanks in series, city water and tests out fine.
This place goes through a lot of water, thermal expansion tank in place an properly sized.
