These days, if you have a new furnace installed in your home, there is a good chance your HVAC technician will recommend what's known as a condensing furnace. They may show you a few models, guide you through picking one, and then make plans to come install the unit. If you still have a few lingering questions about what a condensing furnace is and why you would need one, then you're not alone. Condensing furnaces are a relatively new invention and a lot of homeowners don't quite understand them. Here are some questions you might have – and the answers.
What does a condensing furnace condense?
Condensation occurs when water vapor condenses into liquid water. Most conventional furnaces just send this vapor through the vent or chimney along with the exhaust generated by the furnace. But condensing furnaces actually extract heat from the water vapor, condensing it into liquid in the process. (Vapor becomes liquid water and gives off heat in the process of doing so.) The condensate, which is that liquid water, then flows into a condensate drain or a condensate drain pump to be disposed of.
Why are condensing furnaces so popular?
Condensing furnaces are popular because they are very energy-efficient. They are able to capture more heat from the same volume of fuel because they don't let the heat in the water vapor go to waste. After you have a condensing furnace installed, you should notice that your energy bills go down.
Do you need any extra equipment for a condensing furnace?
Not typically. If your furnace is located a long way from a drain, however, your HVAC technician may need to install a small, extra pump to pump the condensate to the drain. This piece of equipment does not cost much and is easy for them to install. It is generally attached to the side of your furnace and won't get in the way.
Do you have to install a condensing furnace?
There are some furnace companies that make non-condensing furnaces. However, they are few and far between. The only benefit of choosing a non-condensing furnace is that they tend to be a little cheaper. However, a condensing furnace will quickly make up for the difference in costs with energy savings.
Hopefully you now have a better understanding of condensing furnaces, what they offer, and why your HVAC technician is recommending one. They really are the peak when it comes to efficiency.
