Condensation and damp create many problems in the home
As well as being unsightly, it propagates mould growth and musty smells.
Excess moisture can also penetrate your walls causing interstitial condensation, which damages the structure of your home.
Modern houses are like sealed boxes Moisture created everyday from showering, cooking, laundry drying and even breathing builds up.
When the weather gets colder, moisture condenses on cold surfaces like windows or unused room walls.
A dehumidifier attracts this excess moisture and collects it in a water container for safe disposal
Why does condensation happen?
Condensation and dampness usually occur during the winter months when low outside temperatures cool external walls causing condensation and/or mould to form.
We produce moisture by simply living our lives.
It’s estimated that a person breathes out over a pint of water every 24 hours.
Other sources of moisture are boiling pans, a bath or shower, drying laundry.
We live in houses that are like sealed boxes – excess moisture cannot escape.
The excess water we create then travels around the house looking for the coldest part of the house on which to collect. This is usually a window – where the outside temperature makes the window cold.
The excess moisture then condenses and becomes water – or condensation on the window.
How a compressor dehumidifier solves the problem
Excess moisture is always attracted to the coldest point in the house.
The excess moisture in the house then condenses on the cold window and you get unsightly condensation.
During winter this is usually a window – where the external temperature cools the glass.
A dehumidifier stops this by becoming the coldest point in the house. So the moisture is attracted to the dehumidifier and trapped into a water container so it can be safely disposed of down the sink.
Compressor dehumidifiers designed to work well in UK homes in the winter months need to have a lower evaporating temperature because of the low prevailing dew point.
Compressor dehumidifiers designed to work in higher temperatures and/or Relative Humidity should evaporate at higher temperatures because of the prevailing high dew points. This is why you cannot assume that a dehumidifier that performs well at say 21C and 60% will perform at the more lower temperatures and or Relative Humidity which apply for the majority of the time in UK homes during winter months.
The damage condensation can do
Condensation and excess moisture can propagate damp and mould growth. Both of these can impact your health and damage your home.
Excess moisture can also penetrate your walls and wall cavities causing interstitial condensation which damages the structure of your home.
Damp homes also feel cooler. Using a dehumidifier will allow you to reduce your thermostat by 1 degree – with no discernable difference in the feeling of warmth in your home.
