Furnace Efficiency 80 Vs 95

In this type of furnace 20 of the energy produced by natural gas is expelled as exhaust.

Furnace efficiency 80 vs 95.

First of all high efficiency furnaces can have a higher price tag than standard models. That means a 95 afue furnace will cost less to run than an 80 afue furnace. Obviously the 96 efficient furnace will be more efficient using natural gas to heat your home. On paper high efficiency furnaces seem like a good investment both in terms of energy bills and the environment.

A 95 efficiency furnace uses sealed combustion where the heating unit pulls air in from outdoors instead of using air in the home. These days 95 afue is a common rating among new gas powered furnaces. An 80 efficiency furnace burns natural gas using open combustion by pulling air from the surrounding area and exhausting the waste up the chimney. The same amount of money is spent on that fuel being used.

We are often asked what the differences in 80 and 96 efficient furnaces are. High efficiency furnaces offer 90 or more afue. But besides the level of efficiency another key difference between the 80 afue and 95 afue furnaces is that they operate a little differently. Both types of furnaces have single stage or two stage heating models.

The higher cost can lead homeowners to either opt for a less efficient but cheaper replacement or to stay. In fact it is 16 more efficient. A furnace with a 95 efficiency rating uses 95 of the fuel to produce and deliver heat to where it s needed. If your house is well constructed and insulated the waste heat from the 95 furnace should suffice even if it s the only furnace in the basement.

The same amount of fuel is used in both cases. Assuming no mechanical problems as described above i d go with the 95 your tenant s heating bill will be approximately 16 less than with the 80 version. Deciding between 80 96 efficient furnaces. To calculate those savings simply multiply the difference in afue 95 80 15 by your monthly or yearly bill amount.

A standard efficiency furnace provides 80 annual fuel utilization efficiency afue. So a 95 furnace is more efficient than an 80 furnace. The higher the afue percentage the more efficient a furnace is at converting gas into heating energy. But in one scenario 80 of the fuel is used to contribute to delivering heat whereas in the other scenario 95 of the fuel is used to contribute to delivering heat.
