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.
  • 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 FRIEDRICH PROPH50 T2 RH400-30 since 2024-06-24, the JETGLAS RE2HP50**-1NCTT since 2025-07-16. A sale date, not a lifespan.

Which should you pick?

  • Pick the JETGLAS RE2HP50**-1NCTT if running cost matters most: it uses 2 kWh less a year on the same test.
