What Is A Good Efficiency For A Furnace

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

What is a good efficiency for a furnace.

This style of furnace requires you to relight the pilot if it goes out. 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. They rely on drafts or the fact that heat rises to distribute warmth. Its top of the line models are as good as it gets.

Most new furnaces display an annual fuel utilization efficiency afue rating which is a measure of fuel efficiency. High efficiency furnaces offer 90 or more afue. Energy efficiency upgrades and a new high efficiency heating system can often cut your fuel bills and your furnace s pollution output in half. Along with the variable speed fan this feature can really increase the efficiency of your furnace but you typically won t see one unless you are in the northern states.

Upgrading your furnace or boiler from 56 to 90 efficiency in an average cold climate house will save 1 5 tons of carbon dioxide emissions each year if you heat with gas or 2 5 tons if you heat with oil. A standard efficiency furnace provides 80 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. Up to 97 3 afue energy star certified and state of the art modulating valves which increases efficiency even more.

So a 95 furnace is more efficient than an 80. The systems are also often gravity based. If you re looking for the most energy efficient furnace on the market we think trane is your best bet. Modulating valve this is also a high efficiency feature and it allows your furnace to modulate the rate at which fuel is injected into your furnace.

A good furnace brand should offer an 80 to 99 afue rating. These units tend to be between 56 to 70 percent efficient. High efficiency furnaces with sealed combustion don t have this problem and are a good choice for furnaces that will operate from a sealed attic or crawlspace. If you re thinking about encapsulating your crawlspace or insulating your attic with spray foam consider upgrading to a high efficiency furnace at the same time.

You can identify low efficiency furnaces by the use of a continuous pilot light. The total price of a new furnace depends on the brand efficiency and installation costs. Precise comfort technology allows the furnace to keep the temperature held exactly where you want it. Heat is even throughout your home with no cold spots.

These days 95 afue is a common rating among new gas powered furnaces. It might not seem like a worthwhile investment to spend an extra 200 or even 500 for a higher efficiency furnace in your home but with efficiency improvements at such an affordable rate it s often worth it to step up to a better name brand with a more efficient product.
