What does cause condensation? Condensation forms when warm, humid air contacts a cold surface. Moisture is in the air all around us and warmer air can hold more moisture. As air cools, it contracts and its moisture condenses.
What temp gets rid of condensation?
He says setting your heating temperature to 15-17 degrees is a good place to start, explaining: “Condensation can build up on windows when temperatures outside are significantly cooler than those inside.

How do I stop condensation in my bedroom? The atmospheric temperature must always be consistent to stop condensation. Make sure warm air ventilates out of the home and walls and surfaces are not too cold. Try keeping the heat at a low consistent temperature and avoid drying clothes inside.
Does hot or cold air get rid of condensation on windows?
Heating will not help with window condensation in the winter. Condensation occurs when hot air meets cold air at a surface. So the hotter the inside of the house in the winter, the more likely condensation will occur. Instead of raising the temps, run a dehumidifier to pull excess moisture from the air.
Is cold or hot air better for condensation?
Specifically, in order for condensation to occur, you need a body of warm, humid air (humidity is necessary because otherwise there wouldn’t be any water to condense) and a cold surface (the window), specifically colder than the dewpoint of the humid air, on which the condensation is to take plac.
Does cold air get rid of condensation?
Setting your thermostat to a low, even temperature will help prevent cold spots from occuring in the home, which will lessen the chances of condensation taking hold. Make sure you keep that heat going throughout the day, even when you’re not at home, as this will also help keep condensation at bay.
