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 LOCHINVAR HPTS-80 2** since 2022-06-06, the STATE HPTV-80 2** since 2023-07-10. A sale date, not a lifespan.

Which should you pick?

  • Pick the LOCHINVAR HPTS-80 2** if running cost matters most: it uses 375 kWh less a year on the same test.
  • Pick the STATE HPTV-80 2** if it is the one you can get installed sooner or for less — on the filed figures it has no advantage over the LOCHINVAR HPTS-80 2**.
  • Neither if your household's busiest hour needs more than 95 gallons of hot water — neither lists more.
