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).
- Both are ENERGY STAR certified, which requires a manufacturer warranty of at least six years; the actual term for each model is not published.
- Time on the market, as filed with ENERGY STAR: the Custom Comfort CCOHPWH80A since 2025-01-01, the Rinnai REHP80W since 2026-06-30. A sale date, not a lifespan.
Which should you pick?
- Either one: On filed figures these are interchangeable; decide on installed price and availability.
- Neither if your household's busiest hour needs more than 91 gallons of hot water — neither lists more. Check whether a 75-gallon heater is enough.
