Condensation video

Interesting condensation/winter video. Main forum page go to Motorhome General Discussion Problems and click on bcBounders "winter RVing". Information will definitely help in controlling condensation. Mentioned that use of propane by stove/especially furnace major contributors to condensation.

Yes it is very important to run the exhaust fan when using the stove/oven when the RV is closed because of weather. The furnace cannot contribute to condensation inside due to burning propane unless the heat exchanger is faulty.

As Ray noted, a forced air furnace will not add moisture to the heated space. The combustion process dies produce water vapor, but in the furnace, it is in the sealed chamber which is vented outside. However when you use the propane surface burners and oven, you will introduce water vapor into the interior space. You have to vent the coach to help keep moisture down during the winter.

In cold weather, we generally keep a roof vent cracked open about 1/2" day and night. The human body will resiprate a lot of moisture when you breath.

Here is the link to the video.

It is mostly correct. Rather than use steel wool for a rodent barrier, use a bronze wool which can be obtained at most marine stores. The bronze wool will not rust like the steel wool. Also, the electric heater does not actually remove moisture from the air. This is a sensible heating process and drives the air condition away from the dew point which lowers the relative humidity, but still contains the same amount of moisture. If you have a cold surface below the dew point, the moisture will still condense from the air.
