Three Advantages Of A Condensing Furnace

Heating costs are one of the most expensive bills that homeowners have to contend with. If you live in an older home, you will probably have an older furnace. In decades past, gas furnace manufacturers were not as concerned with efficiency as they are today. Thus, if you want to get your heating costs down, you should consider updating your furnace. For the best results, you should install a modulating, condensing furnace.

Electronic Ignition

Older furnaces will use a pilot light to ignite the fuel flowing into the furnace's burner. A pilot light is a constantly burning flame. The problem with this is that your pilot light will use up a lot of fuel which will not go toward heating your home. Newer furnaces will have an electronic ignition switch that will light the gas flowing into the furnace automatically and thus help to keep heating costs down.

A Second Heat Exchanger

Older furnaces will have one heat exchanger which will leave some of the heat in the exhaust flowing out of the furnace. This heat is simply wasted. A condensing furnace has a second heat exchanger, which will extract so much heat out of the exhaust gases that they will condense to liquids and must be expelled from the furnace through drain pipes. This second heat exchanger is important, but you can still get more efficiency from your furnace.

A Modulating Motor

If your furnace's motor only has one setting, it will come on full blast no matter how much heat is required. A furnace with multiple settings can adjust its output to match the demands of your household. If your furnace runs for a long time at a lower setting, you can actually save more money than you could with a furnace that runs in short bursts at full blast. Furthermore, a furnace running at a lower speed will be quieter than a furnace running at full speed. If you are sick of trying to talk over the noise of a thunderously loud furnace, a modulating furnace can be a good purchase. 

You might be worried about the cost of buying a new furnace, but as long as you save more money on your heating bills than you expend on your furnace payments, you will still come out with net savings. Rather than put up with the higher bills, a larger carbon footprint, and the noise associated with an older furnace, you should talk to a furnace installer about how much it would cost for you to get a new furnace in your home.
