Condensation on windows

[DSRamblers]

I am camping in the panhandle of Florida. It got down to 28 degrees last night and will be 25 tonight. When I woke up this morning, I had a lot of condensation on front window and side drivers window. I cracked a window last night and pulled up the front shade but still did not seem to help. Any suggestions to help this situation?? Thanks for your input.

Single pane windows WILL have condensation when the temp difference is great...

Just about everything you do inside generates moisture in the air... your breathing, cooking, the propane furnace, etc.. etc...

Ventilation is the key, they say leave a window open, but I never liked that idea, so I run the electric heat pump which seems to dry it out some...

when I DO run the furnace and lose the front blind, our windshield will be wet

getting a dehumidifier might help too -some friends set their's up in the sink so it drains into there

FWIW do some reading about dew point and dew. Glass in general and single pane in particular is a poor insulator so it will be close to the outside temperature. As long as that is lower than the dew point in your environment water will condense out of the air.

Just to set the records straight, a properly installed and operated RV LPG furnaces does not add moisture to the inside of your coach. The furnace has a sealed combustion chamber which draws fresh air from outside and sends the exhaust back to the outside as well. On the house side of the heat exchanger/combustion chamber, the system draws air from within the coach, passes it over the heat exchanger and returns it to the coach.

If your furnace is adding moisture to your inside air, you have a cracked heat exchanger and your are adding carbon-monoxide to the air which can kill you.

How does a propane furnace generate moisture in the coach when it vents the combustion gases outside?

[nothermark]

A propane furnace does not do it. A propane stove will generate some from the flame. A human exhales 1-2 quarts of water per day under normal conditions. Then there are showers, towels, tea kettles, etc.

Dehumidifier is the best solution.

Also, try and refrain for accelerated heart rate and heavy breathing
Along with a humidity gauge inside to monitor the inside humidity, and try to use methods to keep it lower, especially in colder temps.

We were in temps in the low 20s a few nights last week. Nothing I tried had any effect on windshield condensation. Double pane windows, window cracked open, etc. I conclude it's the cost of doing business in cold weather. It didn't seem to matter if it was the heat pumps or propane furnace providing the heat.

Just wet? Try 24" of frost on the inside of the windshield. 14* will do that for you. Like others have stated, glass is a great conductor of heat or lack of heat.

When taking a shower, run the exhaust fan... then wipe the water off the shower walls, etc. This stopped the condensation in my motorhome.
