Condensation on the inside of the windows

[laserver]

We have a 1995 Winnebago Adventurer. We are living in it full time for the summer. This morning we woke up to a lot of condensation inside on every window. Heat was set to 75 and outside was damp and unusually chilly. Is this normal?

We just found out the hard way that humidity and moisture are concerns for RVs.

Running the air conditioner can act as a dehumidifier in the summer months. But a real dehumidifier is important. They also make desicants that are nice; Walmart sells them cheap in the RV/Boat section. Baking soda and charcoal also absorb moisture.

Hope this helps.

if single pain windows....yes

Yes this is single pane glass. So too much humidity? What about setting the inside temp at 70?

If running heat on propane you are introducing tons of moisture. Lower the heat crack a window, turn on a fan. Yes in many RV's this is a problem. High humidity cliamtes, and a closed up warm rig will do it every time. You need to move more air and possibly get a dehumidifier.

There's only 2 ways to stop condensation, get rid of the moisture or lower the dew point. An old supermarket trick to lowering the dew point was to raise up the temperature. Stores that were sweating at 70 degF magically dried up when the temps were raised to 74. Also air circulation can help. If you have shades in front of your windows, try and raise them enough so that you get a little air movement underneath them, so the windows don't get quite so cold.

Propane heat does not add any moisture to the inside of the RV. The combustion process is completed in the heater in an outside vented chamber. The air passes over the combustion chamber and is heated with a sensible heat. The heating process for the propane heat or electric heat is exactly the same on the psychometric chart.

The OP needs to lower the humidity inside the RV by venting more and being careful to reduce humidity over all. Cooking, shower and breathing put moisture in the air. Keeping a top vent cracked open will help to reduce the moisture.

Thanks everyone. We will try the cracked window/vent tonight. We are at 8000 ft on Bryce Canyon
