Gas Furnace Efficiency

The price of a furnace generally rises in step with its fuel.

Gas furnace efficiency.

It represents the ratio of annual heat output compared to the consumed fossil fuel energy. Lennox slp99v variable capacity gas furnace series. The best gas furnaces cost between 2 500 and 3 500 and some even go up to 5 000 if you re heating a larger home. The daikin hvac unit operates supply stores in more than 64 locations around the world.

Furnaces that are a couple of decades old have an afue rating of around 60 percent meaning that 60 percent of the fuel becomes heat and 40 is lost. These are energy star certified furnaces with 90 to 98 percent afue ratings. Most gas furnaces by daikin offer variable speeds balanced heat improved fuel efficiency as well as reduced wear and tear. The efficiency of a furnace is measured by the annual fuel utilization efficiency afue.

The lowest efficiency allowed by law for new gas furnaces is 78 percent and some new models achieve 97 percent near total efficiency. Precise comfort technology allows the furnace to keep the temperature held exactly where you want it. On the afue efficiency ratings daikin furnaces enjoy the top 98 level. Furnace efficiency is measured in afue annual fuel utilization efficiency which determines how efficient the appliance is in converting fuel to heat.

The efficiency of a gas furnace is measured in annual fuel utilization efficiency afue and we ve included many of the most efficient gas furnaces in this guide with ratings of over 90 afue. The higher the afue the more efficient the furnace. You can expect 90 to 98 5 percent efficiency. This premier furnace boasts an efficiency rating of up to 99 that means it essentially converts every last bit of energy it uses into heating the home.

High efficiency furnace use variable or modulated speed blowers that automatically adjusts to the heating needs of your home and sends the right amount of airflow to keep the temperature perfect or within 1 degree at all times. The afue measurement measures the amount of fuel converted to heat in the space in proportion to the amount of fuel that enters the furnace.
