help please with a dehumidifier?

[berniecuddles]

getting loads of condensation on our windows (inside) mostly in main bedroom and front living room windows, the wallpaper under the window in the bedroom is soaking wet all the time, so today we invested in a Challenge 12 Litre 3 Litre Tank Dehumidifier from argos.
easy to set up and already it is doing its job collecting water.
having never used one before do i have to have it on 24 hours a day or just at night,or can i put it on in the morning when we go to work as it is a bit noisy in our bedroom!
any help for a time setting please, thx all!

I do the opposite. Since it is when you are in the room that the moisture is introduced I run mine overnight. You soon get used to the noise, unless it is very loud.

I leave mine on 24/7 but obviously turn it off in summer as it makes a bit of heat, which is good for drying out boots etc

Are humidifiers good for damp rooms?

[netibiza]

Well they collect a lot of water, but I still get condensation!

Go wth Eddies approach. The walls and furnishings act as a reservoir so if you have the dehumidifier on during the day the walls etc. dry out and tjhen absorb moisture at night, we have an independant humidity meter in the bedroom as well as they DH. The humidity doesn't go up much at night. When you start using a DH the humidity drops quickly until moisture starts to come out of the walls and then the humidity drops more slowly until you get to 30% which is the lower limit of the DH as it begins to ice up at this level. There is no need to have the noise at night it will be fine if yoiu just use it during the day. If you keep an eye on the external humidity you can open the winows when it is lower outside ( and not too cold) and get free dehumidification.

Bernie, have you got any ventilation in the problem rooms other than when the window is opened??As you do seem to have a problem, which is possibly due to a lack of "air change".
