Condensation in Pennsylvania RVs

Condensation in RVs is common and, over the years, I have had lots of questions regarding condensation,so we’re here to explain what it is and how to minimize it in your RV.

Condensation is defined in the Merriam-Webster online dictionary as: a chemical reaction involving union between molecules often with elimination of a simple molecule (as water) to form a new more complex compound of often greater molecular weight.

Condensation happens when the surface the condensation has gathered on is cooler than the temperature of the water vapor that created the condensation. Where there is a high level of humidity from normal day activities, such as cooking or showering, condensation will form when this humid air comes in contact with colder surfaces, which causes dampness on surfaces.

While most RV manufactures can’t guarantee an elimination of all condensation, I would like to provide you some tips to lessen the condensation that happens inside your RV. When you’re cooking or showering, be sure that you’re using the roof vent fans. The fan will pull the moisture out of the unit, reducing the chance for it to collect on the windows and the walls. Using an extra fan to help move the air around inside of the RV can also help. Another idea to reduce the chances for condensation to form is to use the microwave to heat up water, rather than the stove, to contain the moisture and limit the amount that is allowed into the air. If no microwave is available, opening a small window while heating water on the stove will allow the moisture to escape. In addition, using a small de-humidifier inside of your RV will help with removing the moisture from the air.

The more you allow the moisture building inside of your RV to escape and move the air around so it has less of a chance to settle, the less condensation you’ll find in your unit. If you use these tips and adapt them to other purposes, you’ll be able to reduce the amount of condensation that forms on your walls and windows inside your unit.
