What is the efficiency of the furnace?
It is estimated that 35 million houses in the United States (US) are heated by natural gas through heating forced air. Unfortunately, most houses lose 30% of this heat before it gets into residential areas. The heat escapes by smoking and other areas of the heating system. In addition, many older furnaces burn twice the fuel necessary to ensure heat. These furnaces have a very low efficiency level. The percentage of fuel that turns into actual heat is called the annual efficiency of fuel use (AFUE) is marked as low, medium or high efficiency. Models with low efficiency, below 78% AFUE, are older and not generally for sale. Model efficiency models begin to 78% and increase up to 90%. Whatever above this level is considered to be of high efficiency. In 1992, the US Energy Ministry set the minimum level of AFUE on a new furnace at 78%.
AFUE AFUE AFUE is printed on a sticker on Yellow Energy Guide Appliance, located in a prominent location. This number is only PRAbout the furnace itself, not for the entire heating system. Having a very high furnace efficiency will not help with leaks in the ventilation openings. The size of the house can also change the furnace efficiency. It is important to buy a furnace that is large enough for space, that it is heating, but not too large. The furnace, which is too large, turns on and turns off more often than it should, and loses a lot of fuel.
Just because it is an old furnace does not mean that it needs to be replaced for a newer model. There are many ways to improve the efficiency of older furnaces. One way is regular pipe cleaning, as clean channels allow you to pass more heat. Air filters should be changed every three months. Check all holes pipes and have them repaired. Rentopofesional for cleaning and control of the furnace. The professional often knows several tricks to safely improve the furnace efficiency without having to replace the whole system.
The efficiency of the furnace is one of the most important factors that need to be considered when attempting to reduce the cost nand heating. Having a highly effective furnace can save thousands of dollars throughout the life of the furnace, usually 20 years. A furnace working with AFUE more than 90 can save homeowners around $ 10,000 in US lifetime. This can quite change the annual heating accounts.
