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.
