Moisture Control - Problem Solving

RV Zones Insulation & Moisture Control

Let’s nip this problem at the bud. The approach is to create a small amount of ventilation that will replace the humid air in the RV with less humid air from outside. An example of how to do this is to install two ceiling fans. One fan will push air out and the displaced air will draw air in through the other fan.

What is the issue with Moisture in an RV?

Moisture control in an RV (Recreational Vehicle) is a significant issue due to several reasons:

  1. Condensation: RVs are small, enclosed spaces where activities like cooking, showering, and even breathing can produce a lot of moisture. This moisture can condense on the walls, windows, and other surfaces, leading to dampness.

  2. Mold and Mildew: The dampness caused by condensation can lead to the growth of mold and mildew. These can cause health problems and damage the interior of the RV.

  3. Structural Damage: Excessive moisture can lead to structural damage over time. It can cause wood to rot and metal to rust, which can weaken the structure of the RV.

  4. Insulation Problems: Moisture can also damage the insulation in an RV. Wet insulation doesn’t work as effectively, which can make the RV less energy efficient and comfortable.

  5. Odor: Dampness and mold can cause unpleasant odors in the RV.

Managing Moisture

To manage moisture in an RV, it’s important to have good ventilation, use dehumidifiers if necessary, and regularly check for signs of dampness or mold. Installing fans, like the MaxxAir fan mentioned earlier, can also help circulate air and reduce moisture levels.

Important Tip: In areas prone to moisture problems, make sure there is airflow, even if it means creating gaps and/or holes for fresh air to flow. This includes cabinets, under your refrigerator and freezer, a cabinet you might store damp flip-flops, and anywhere moist air can collect.

The Eberspacher Furnace in the RV will circulate all of the air every 10 minutes. Additionally, we would like to replace 5-10% of the air in that same period of time. It is more work for the furnace but it does remove the humidity and ultimately will solve the problem

This is also a challenge when running under air conditioning, however, air conditioners have a dehumidifying effect and the excess water will drain from a tube through the floor of the RV.
