According to a study published in the Journal of Building Engineering, radiant floor cooling can be 30% more efficient than air conditioners. As a result, you can save money on your energy bills each month. And, over time, savings can really add up.

Quiet Operation

Another benefit of radiant floor cooling is that it’s quiet. That’s because there’s no fan blowing around the air. As a result, you won’t have to deal with the noise of an air conditioner running in the background.

That can be a significant benefit if you’re trying to sleep or concentrate on work. It can also be beneficial if you have young children in the home who need to nap during the day.

Disadvantages of Radiant Floor Cooling

Although radiant floor cooling comes with several benefits, there are also some potential drawbacks. 

A few notable disadvantages of radiant floor cooling include:

High Installation Cost

Arguably, radiant floor cooling is costly. That’s because it’s a more complex system than traditional air conditioning. As a result, it can cost more to install.

Additionally, radiant floor cooling systems often require specialized materials and equipment. That can also drive up the cost of the system.
