What it costs to run
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 above.
- No CPSC recall on file names either model (list checked 2026-09-24).
- The actual warranty term is printed in each model’s documentation, not in any registry.
Which should you pick?
- Pick the Richmond PROP G50-50* RH HE EC3 if running cost matters most: it uses 76 therms less a year on the same test.
- Pick the State GURT-50RL 4** if it is the one you can get installed sooner or for less — on the filed figures it has no advantage over the Richmond PROP G50-50* RH HE EC3.
- Neither if your household's busiest hour needs more than 95 gallons of hot water — neither lists more. Check whether a 50-gallon heater is enough.
