CAMMOO RV-65000B vs CAMMOO RV-65000W: which uses less energy?

At the very small draw pattern the CAMMOO RV-65000B and the CAMMOO RV-65000W use the same energy, 23 therms a year each, on the same federal test. Both are filed as a gas tankless unit, so the comparison holds; what separates them is below. Enter your ZIP to price either one on your own rate.

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 CAMMOO RV-65000B if its price or availability suits you — on energy the two are level.
  • Pick the CAMMOO RV-65000W if it is the one you can get installed sooner or for less — on the filed figures it has no advantage over the CAMMOO RV-65000B.
  • Neither if you need more than 1.6 GPM at the same time — neither unit lists more. Check how to size a tankless unit by GPM.
