Reliability

Not published: Reliability, failure rates and each model’s actual warranty term.

The registries these figures come from certify energy performance under a federal test; none of them records how long a unit lasts or how often it fails, so this page does not rank the two on reliability.

What is here instead:

  • The filed efficiency, capacity and tank size of both models, side by side below.
  • The actual warranty term is printed in each model’s documentation, not in any registry.

Which should you pick?

  • Pick the Rheem XG50T12HE40U0 if running cost matters most: it uses 4 therms less a year on the same test.
  • Pick the GE GG50S**BXR01 if it is the one you can get installed sooner or for less — on the filed figures it has no advantage over the Rheem XG50T12HE40U0.
  • Neither if your household's busiest hour needs more than 77 gallons of hot water — neither lists more. Check whether a 50-gallon heater is enough.
