Why does condensation gather on the inside of windows?
Answers:
Do you have gas heating? Gas contains a great deal of water and when it burns the water is released into the air causing an elevated humidity. This condenses on the cold windows.
A possible solution is to buy a de-humidifier.
Another solution is to have a window open a small amount.
Obviously - not having gas heating is a 3rd solution, but gas is not the only source of moisture in the air - people produce moisture - go and breathe on a mirror and see. You also add moisture to the air from your skin - evaporation of your perspiration.
Putting the heating on will work if it warms the windows enough that the water doesn't condense, but the water will still be in the air. A humidifier is probably your healthiest solution as living in a very humid atmosphere is not particularly healthy.
I had double paned windows and got condensation on the inside because there was a leak and it wasn't really sealed. If you have single paned windows, I have no idea.
Usually when my house has high humidity, (when I run my humidifier for a long time and windows are all shut) I get the condensation on my windows. If this is the case for you, (if you happen to live in a humid area) you might want to try a dehumidifier. You could try the heat trick. It might work, but it could get expensive if you are heating rooms that you aren't using. Good luck.
there is a lot of water in your flat somewhere
hope it will dry out in a couple of days
That could be humidity in the rooms and cold outside which cools the moisture and drips on the window. If condensation is between the glass the seal can be cracked.
outside temp is cooler tha the inside temp,
plus there is higher humidity on the inside of your home
Condensation occurs because the air that comes in contact with the cold surface is humid; this is the same mechanism that causes a glass with a cold drink in it to get wet from condensation. Heat will increase the amount of moisture that the air can hold, so it could actually make the condensation worse. I suggest getting a dehumidifier for the room.
You can't take all the moisture out of the air. After all, every time you exhale you spew out a lot of moisture with your breath (that's why a car's windows will fog up when you get inside when they were clear before - all that water is coming out of your lungs!). Even if you could, breathing completely dry air isn't too great for you either. The only option you have that I see is to just prevent it from forming on your windows.
If you're really dedicated to doing this, the best way is probably to heat the window glass, NOT the room! If the room is warm and the glass is cold, you're just going to make the problem WORSE! Some high-tech bathrooms are equipped with heated mirrors for this reason - even if water DOES settle on it, it quickly evaporates again.
Hope that helps!
Condensation forms on the "warm" side of things! Example:
1. A glass of cold beer, the condensation is on the outside because that surface is warmer.
2. Your window. If it is warmer inside your home, the condensation forms on the inside. Conversely, If you are in a hot country and have Air Conditioning. Your home is colder and the condensation forms on the outside (Warmer) surface.
3. Condensation is formed when the air reaches saturation point (Dew Point) this is the humidity in the air.
With new windows you should have no condensation.When this occurs it means that your windows are not sealed properly.Cooking will cause your windows to fog over but if it is on the inside you have not got a proper seal.
Some tips for reducing humidity in your home:
Use the exhaust fan in your bathroom when taking a shower and let it run for awhile after you finish showering.
Use the exhaust fan over your stove when cooking (and make sure it is a true exhaust fan to outdoors and not simply redirecting into your kitchen).
Don't use a kerosene heater.
Lower the humidity in you home. To be comfortable the humidity should be between 30 and 50 percent. (Get a thermometer with a humidstat at you local hardware or WalMart.)
If you cook, use a fan to exhaust the humidity that produces. The same when taking a shower or bathing, use an exhaust fan afterward to get rid of the excess humidity.
If that doesn't do it, get a dehumidifier.
You can find a lot more help by googling for information about "humidity problems."
If the glass is cold and it's warm and moist indoors, you're going to get condensation - double glazing or not!!
