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 Friedrich PROE40 M2 RH95 if you need more hot water in your busiest hour: it lists a first hour rating of 55 gallons against 53.
- Neither if your household's busiest hour needs more than 55 gallons of hot water — neither lists more. Check whether a 40-gallon heater is enough.
