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 Eemax SPEX60T if running cost matters most: it uses 6 kWh less a year on the same test.
- Pick the Kwickshot TEF055V240 if it is the one you can get installed sooner or for less — on the filed figures it has no advantage over the Eemax SPEX60T.
- Neither if you need more than 0.6 GPM at the same time — neither unit lists more. Check how to size a tankless unit by GPM.
