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.

Which should you pick?

  • Pick the JETGLAS RG2PV40T*N19 if running cost matters most: it uses 7 therms less a year on the same test.
  • Pick the AMERICAN STANDARD WATER HEATERS PV40TLN* if the installed price matters more than the running cost: its modeled installed range is $1,993–$3,665 against $2,110–$3,965.
  • Neither if your household's busiest hour needs more than 78 gallons of hot water — neither lists more. Check whether a 40-gallon heater is enough.
