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.

- Pick the Rheem PROE38 S2 RH95 B if it is the one you can get installed sooner or for less — on the filed figures it has no advantage over the LOCHINVAR ENL-36 2**.
- Neither if your household's busiest hour needs more than 51 gallons of hot water — neither lists more. Check whether a 30-gallon heater is enough.
