Water Heater Tip: What Does AFUE Mean?

When you purchase a new boiler, water heater, furnace or any other equipment depending on fuel combustion to operate you need to know that that equipment will work efficiently. With the costs of fuels such as oil, electricity and natural gas as high as they are you simply cannot afford to waste energy in your Phoenix home. Luckily it is actually pretty simple to ensure that the furnace, boiler or tank water heater that you are investing in will live up to your efficiency expectations. You just need to check out the AFUE of that piece of equipment. If you are unsure of what AFUE means in relation to your boiler, furnace or tank water heater, let the pros at Cool Touch help you understand.

Basically, the AFUE is the measurement of a fuel-burning machine’s fuel efficiency. It stands for annual fuel utilization efficiency. The Federal Trade Commission mandates that all new devices display the AFUE at which they operate so that consumers can easily compare their furnace, boiler and tank water heater options.

The AFUE is a ratio comparing the heat output of your furnace, boiler or tank water heater over the course of a year against the amount of fossil fuel energy that it consumes. If the AFUE of your tank water heater is 85%, then, that means that 85% of the fuel used is actually utilized to heat water, while 15% is wasted. This ratio is specific to the tank water or heating system itself, and does not take into account any energy wasted by ductwork or air leaks.

To learn more about how you can get the most out of your tank water heater in Phoenix, call Cool Touch today. We are happy to help you better understand AFUE ratings. Everyone deserves to get the most efficient equipment they can to use the energy they pay for as completely as possible.
