Helpful Water Heater Terms and Definitions
In the lists above, we’ve mentioned some terms that may be new to you. Here’s what they mean.
This is the symbol for nitric oxide and nitrogen dioxide, generally measured in parts per million or PPM. These are natural products of the combustion process (your car also produces them), but they must be vented safely to the exterior of your home. Canada, the USA, and other countries are trying to reduce these, so the less the better.
This shows how much hot water your system can produce. While this depends on the desired temperature, Navien provides measurements at a few standard temperatures so you can get the idea. Ask your Dr HVAC consultant for specifics.
This stands for annual fuel utilization efficiency, and is the percent of fuel that gets converted to heat. As you might guess, the higher the number the better, as you want as little wastage as possible.
