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.
- The Vesta VRS-199 is named in CPSC recall 26026; see the recall page for which units and the remedy.
- The actual warranty term is printed in each model’s documentation, not in any registry.
Which should you pick?
- Pick the Noritz NCC199CDV (GQ-C3261WZ-FF US) if running cost matters most: it uses 5 therms less a year on the same test.
- Pick the Vesta VRS-199 if the installed price matters more than the running cost: its modeled installed range is $2,358–$3,405 against $2,499–$3,570.
- Neither if you need more than 5.5 GPM at the same time — neither unit lists more. Check how to size a tankless unit by GPM.
