Electric tank water heater?
Hi. I am back and forth about purchasing either the Rheem Marathon or your run-of-the-mill steel tank electric hot water heater. I have read that the Marathon series is no more efficient than a standard tank (EF factor), however, has the advantage of not rusting out. So what's the advantage of all that foam on the Marathon? It costs 2/3+ more and its tank is made out of polybutylene which is a bit worrisome. Any recommendations on kind, as well as sizing (2 adults, 2 kids; are fairly water conservation minded); I'm thinking an 50-75 gallon would work? With all that said, should I consider tankless?
Thanks in advance. Matt
