Have you ever seen water droplets on your windows on a cold morning?
That's condensation happening when moisture in the air meets a cold surface. The main source of this moisture is us, the people living in the house. But have you ever thought about how much water vapor we add to our homes each day?
What Activities Lead to Condensation?
Everyday activities release water vapor, raising humidity and causing condensation. Here's how much moisture common activities produce:
Boiling a Kettle
When you boil water, steam escapes. For example, boiling half a liter for two cups of coffee releases about 10 grams of steam. Making 8 cups a day adds around 80 grams of water vapor to your home.
Cooking on the Stove
Cooking without a lid lets more steam escape than using one. Boiling pasta for 10 minutes in 2 liters of water releases about 100 grams of vapor. Using a lid not only keeps moisture in but also helps water boil faster, saving energy.
Using Washing Machines and Dishwashers
The water vapor from a washing machine depends on the wash temperature and drainage. A typical cycle releases 25-50 grams of vapor. Dishwashers are usually sealed, releasing minimal steam, but opening them after use can release up to 20 grams of vapor, especially in small kitchens.
Drying Clothes Indoors
Wet clothes hold a lot of water. A bath towel can retain up to 1 kilogram of water. Drying clothes on a radiator releases this moisture, reduces radiator efficiency, and can cause fungal growth. Tumble dryers are better, but if not ventilated, they release steam indoors.
Bathing or Showering
Baths and showers add about 1.7 kilograms of water vapor to the air. That's why a good bathroom extractor fan is important.
Breathing
We release water vapor with every breath, averaging 400 grams daily. At night, with windows and doors closed, this builds up, making window condensation more likely due to cooler outside temperatures. Total Water Vapor from a Person If someone: - Drinks 8 cups of tea or coffee - Boils water for 10 minutes - Takes a shower - Uses the dishwasher - Washes and dries 2 kilograms of clothes - Breathes normally They add about 2.5 kilograms of water vapor to their home’s air, which is like 10 glasses of water.
Why Ventilation is Important
Without proper ventilation, moisture collects on cold surfaces like windows and walls, causing condensation, dampness, and mold. Installing good extractor fans in kitchens and bathrooms helps control moisture, protect your home, and improve air quality.
