water on windows

Thanks for the replies.

I talked to my wife and we're thinking about getting one. Seems like it would be worth the money especially if it also helps with the cooling in the summer.

Where does the water go?

Do you run a drain line?

Which model did you buy?

Most come with both options a hook up for a drain hose and a cup holder. Most shut off if cup becomes full. Be SURE to check that it does have this option!

In an RV the best place for it is midship which also is usually where your shower is located. Perfect place to set the dehumidifier close to the wall out of the way and Run drain hose into shower.

I found all the midrange priced ones from Lowes or Home Depot all work fine.

BTW running a dehumidifier in the summer months also really helps your AC cool down the inside. I couldn't believe the difference.

ArchHoagland it has a hold tank with a shut off float that you have to empty. When I first started to use it the tank was almost full. Now that I run it every day or so when it's cold I only get maybe 2 to 3 cups of water a night. I didn't use a drain line so I could move it to the bedroom or living room. It is a Kenmore 30 pint it's 20"H X 14"W and 10"D.

Why do I have so much condensation on my windows? I'm at my wits end.

Because the glass temperature is below the dew point in the RV.
Reducing humidity or double pane glass is the solution. Make sure your weep holes are clear and ignore it. Or use a squeegee.

At night we leave the exhaust fan running in the rear of our coach and a window cracked up front. If we don't do that the windshield in the morning will look like it rained inside during the night.

We put a couple blankets on and keep a electric heater going on low but it has gotten down to 42 inside a couple times. I turn on the furnace in the morning and it warms up pretty quick.

Two people breathing produce a lot of moisture and that is what causes the problem.

As already stated, cooking , showers and a propane furnace, or simply breathing all dump a lot of moisture in the Air and if you have single pane windows in cold temps outside you will get moisture on them .. double pane windows not so much. You can control it to some degree if you open a window slightly and open or better yet turn on a roof vent for air flow.
When warm air with moisture meets cold (cold windows) it condenses , I had that problem with my old single pane poorly insulated trailers but now with double pane and better insulation in my last two coaches ... no more!

Typically when it's cold, the natural thing to do is close everything up tight to keep things warm and prevent drafts. You really need to have a vent or window open for circulation or you'll fog up.

Tell us more. Do you have single or double pane windows? Is it cold outside? Do you provide good ventilation (roof vent with fan) when you cook, take showers, etc?
