There’s no denying that heating can indeed be very expensive and in case you’re not careful, you could end up with a huge energy bill at the end of the month. The key to efficiency is to control your heater throughout winter in such a manner that you not only have lower energy bills but also enjoy a warmer environment. 

However, it should be realized that you cannot increase your heater's efficiency artificially and your heater must be able to support higher energy star ratings to be able to do it. But how do you find out whether your heater is efficient? That's why in this report, we are going to discuss some of the significant ways through which you can find out the efficiency of your heater – connected to Honeywell thermostat

Procedures To Find Out The Efficiency Of Your Heater

  • Knowing Your Heater’s AFUE Rating

AFUE or Annual Fuel Utilisation Efficiency is always the best way to judge your heater's efficiency. It should be realized that AFUE is a percentage that shows how well a heater can convert fuel into energy. This means – the higher the AFUE rating, the higher will be the efficiency. 

For instance, a heater having a 98 percent AFUE rating means that 98 percent of the fuel that the heater is consuming is being used and only 2 percent is being lost. However, you must remember that old-age heaters have an AFUE rating as low as 56 percent or even 44 percent. 

You should be able to find your heater’s AFUE rating inside the user manual. In case you’re not able to find the same, then you can either contact the manufacturer or head over to the product’s website to know about the AFUE rating. 

To consider a heater to be highly efficient, it should have an AFUE rating of at least 90 percent, even though having 80 percent AFUE rating is typically considered to be sufficient overall. The minimum percentage, however, is 78 percent. 

  • Knowing Your Heater’s Overall Age

Once you've already delved into the concept of AFUE rating, it's time to start evaluating the heater's overall age. It should be retained in mind that the average life expectancy of a heater is about fifteen to twenty years. Even though your heater might have an excellent AFUE rating, the rating is said to decrease at 5 percent every year. 

Even if you take excellent care of your home equipment, it will still degrade over time and components will continue to wear down as well. So, if your heating system is more than ten years old, you should proceed to replace it first.
