Glass Lined versus Stainless Steel
I am replacing my water heater (Rheem 75 gallon power vent nat gas) with an indirect HW heater. My plumber is insisting that the Glass Lined Superstor Contender is the way to go. Reading the documentation available on the web leads me to believe that the Stainless (Superstor Ultra) is a better option. The documentation reports a much higher first hour rating for the stainless .
