UEF or Uniform Energy Factor

This is a new metric for determining the energy efficiency of a water heater. The highest numbers are better (and lower your energy bill).

Flow Rate

How much hot water can be produced in gallons per minute and litres per minute. This will depend on the desired temperature.


This stands for two compounds: nitric oxide and nitrogen dioxide. While they are natural products of combustion, they must be safely vented. As they are also pollutants, Navien tries to keep NOx emissions to a minimum to comply with Canada’s reduction strategy. They are measured in PPM or parts per million.
