Are you looking for a way to cool your RV other than an air conditioner? Then, an RV evaporative swamp cooler may be the answer. This article explores what a swamp cooler does and its benefits. And we reveal if it’s actually better than a traditional air conditioning unit.
Let’s get started by taking a closer look at what a swamp cooler is and how you can use it in an RV. Then check out six of the best RV evaporative swamp coolers on the market today.
What Is a Swamp Cooler?
A swamp cooler, also known as an evaporative cooler, passes outdoor air over water-saturated pads. The water in the pads then evaporates, reduces the air temperature by 15 to 40 degrees, and releases the air into your RV. Windows should be left open slightly when running a swamp cooler to allow the warm indoor air to escape and be replaced by the cool air.
Can You Use a Swamp Cooler in an RV?
You can use a swamp cooler in an RV in dry climates. If you use one in humid climates, you’ll likely end up with condensation and humidity in your space and on the windows. Overall, an RV evaporative cooler is a perfect alternative to an air conditioner as it uses less power and still gets the job done.
Do Evaporative Coolers Work Better Than A/C?
RV swamp coolers are more far more energy-efficient than regular air conditioners, using 90 to 97% less electricity. But you do have to supply the swamp cooler with water constantly, so there’s more work involved. And since they work as evaporators, they work best in very hot and dry climates. For example, if you’re in a desert region, the swamp cooler is a good option than an air conditioner. This is because it will add moisture to the air.
Air conditioners use a lot of power but have the added benefit of dehumidifying. In hot humid climates removing moisture from the air is essential for comfort.
If you use a swamp cooler in humid climates, mold and mildew will likely grow since they add more moisture to the air. Therefore, using a swamp cooler in humid locations is not recommended. Instead, an air conditioner will be a better choice in a humid climate since it works to dry out the air.
Pro Tip: We uncovered all you need to know about an RV air conditioner in our Complete Guide to RV Air Conditioners.
What Are the Benefits of an RV Swamp Cooler?
The main benefit of an RV swamp cooler is that it uses less electricity than an air conditioner. It can be an excellent option for boondocking or those running off solar power. Or, if you’re in a campground that charges for electricity, a swamp cooler is an alternative budget-friendly option. And overall, a swamp cooler costs less than an air conditioner.
What Are the Disadvantages of an RV Swamp Cooler?
Disadvantages of an RV swamp cooler include maintenance and noise. The cooler requires the pad to be changed regularly and constantly filled with water. Unlike an air conditioner, you can’t just leave it and go without making sure it has enough water to operate properly. Some evaporative coolers also tend to be noisier than air conditioners as well when placed in your room.
