RV Swamp Cooler

Have you been considering investing in an RV swamp cooler? If so, you’re definitely not alone. With summer temperatures soaring and camping trips on the rise, it only makes sense that you’d want to be able to stay cool while spending time in your RV.

Unfortunately, information on swamp coolers for RVs can be a bit hard to come by. Therefore, unless you’re already an expert on these less-than-common appliances, you might need some help when it comes to deciding whether a swamp cooler is for you—and if so, which one you should get.

What is a Swamp Cooler?

Let’s start by discussing what a swamp cooler is. Also known as an evaporative cooler, a swamp cooler uses the evaporation of water to cool the air. It does this by using a fan to blow air through a wet pad, creating a lovely cooling effect.

Because water absorbs a decent amount of heat in order to evaporate, the evaporation process actually does a pretty good job of cooling a space, especially in dry hot places such as the southwest.

That said, RV swamp coolers are not as effective as air conditioners when it comes to cooling extremely hot or humid spaces. Therefore, this is not something you’d want to have in place of an air conditioner. Instead, you’d want this appliance in addition to a traditional A/C unit.

Reasons to Invest in a Swamp Cooler

So why would you invest in a swamp cooler? Well, the number one advantage a swamp cooler has over an air conditioner is the fact that it uses far less electricity. This is good for RVers for two reasons:

  1. Any electric bill that the RV owner must pay will be significantly reduced.
  2. Those who prefer dry camping can run an RV evaporative cooler using a generator or solar power.

Of course, many people also appreciate the fact that swamp coolers are eco-friendly. Additionally, because they are such simple appliances, they are relatively easy and inexpensive to maintain and repair if necessary.
