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 below.
- The actual warranty term is printed in each model’s documentation, not in any registry.
Which should you pick?
- Pick the CAMPLUX JSLG44-26VE1(2") if running cost matters most: it uses 6 therms less a year on the same test.
- Pick the Noritz NRC711-OD-NG if you run more fixtures at once: it lists 4.3 GPM against 4.1.
- Neither if you need more than 4.3 GPM at the same time — neither unit lists more. Check how to size a tankless unit by GPM.
