How Does a Whole House Dehumidifier Work in Winter?

Overview of Winter Climate in Europe

1. Temperature distribution

Northern Europe (Norway, Sweden, Finland, Iceland)

Average: -5 ℃~-20 ℃, with temperatures as low as -30 ℃ within the Arctic Circle.

Coastal areas experience slightly higher temperatures due to the regulation of the North Atlantic warm current.

Western Europe (UK, France, Belgium, Netherlands)

Average: 0 ℃~8 ℃.

Winter is mild, with more rain and less snow.

Central Europe (Germany, Poland, the Czech Republic, Austria, and Switzerland)

Average: -5 ℃~5 ℃.

The Alps are cold with heavy snow, often reaching temperatures below minus ten degrees Celsius.

Eastern Europe (the European part of Russia, Ukraine, Baltic States)

Average: -10 ℃~0 ℃, often below -20 ℃ under the influence of cold fronts.

Southern Europe (Spain, Italy, Greece, Portugal)

Average: 5 ℃~15 ℃.

Coastal areas are mild, while mountainous areas are cold (Pyrenees, Apennine Mountains).

 

Humidity characteristics

Northern and Western Europe: The humidity is relatively high (70%~90%), and coastal areas often have rainy and snowy weather.

Central Europe: Moderate humidity in winter (60%~80%), with obvious dampness and coldness in cold weather.

Eastern Europe: The inland winter air is relatively dry (50%~70%), but the low temperature is significant.

Southern Europe: Mediterranean climate, with high humidity in winter (65%~85%), making it the season with the most rainfall throughout the year.

 

Probability of extreme weather

Cold wave:

High risk: Inland Eastern and Northern Europe (cold air intrusion, sudden temperature drop).

Medium risk: Central Europe.

Low risk: Western Europe, southern Spain, southern Italy.

Blizzard:

High risk: Alps, Carpathians, Nordic interior.

Medium risk: Central European plains such as Germany, Poland, the Czech Republic, etc.

Low risk: Coastal areas of Western Europe and most of Southern Europe.

Storms and heavy rainfall:

High risk: Atlantic storms are common along the coasts of Western Europe (such as the UK and western France).

Medium risk: The Southern European Mediterranean region experiences heavy winter rainfall.

Freezing and Freezing Rain:

High risk: Significant traffic disruptions in Central and Eastern Europe.

Occasionally appearing along the coasts of Western and Northern Europe.

 

The value of whole house dehumidifier in a humid winter climate

In winter, many regions in Europe, especially along the coasts of Western, Southern, and Northern Europe, experience a climate characterized by low temperatures but high humidity. The air is humid and cold, and the indoor humidity is heavy, which can easily cause walls, furniture, and clothing to become damp or even moldy. At this point, the Whole House Dehumidifier is very valuable.

 

1. Improved indoor comfort

In winter, the temperature is low, and when indoor heating is turned on, the warm air encounters high humidity, which can make people feel "chilly".

The whole house dehumidifier can maintain an ideal humidity of 40%~55%, reducing the feeling of dampness and coldness, making the heating effect more obvious.

2. Protecting buildings and furniture

High humidity can cause mold and peeling on walls, as well as expansion and deformation of wooden furniture.

Dehumidifiers can reduce air humidity and extend the lifespan of indoor decorations and furniture.

3. Health protection

A humid environment is prone to the growth of mold, dust mites, and bacteria, and air circulation is difficult when doors and windows are tightly closed in winter.

The use of whole house dehumidification effectively reduces indoor allergens and protects respiratory health.

4. Coordinate with the HVAC system

Whole house dehumidifiers are usually connected to HVAC (Heating, Ventilation, and Air Conditioning) systems and work in conjunction with heating systems to automatically regulate humidity.

More energy-efficient and uniform than using a portable dehumidifier alone.

5. Role in Extreme Weather

Continuous rainy weather in winter (in Western and Southern Europe) or snowmelt and moisture regain after heavy snowfall (in Central and Northern Europe) can increase indoor humidity.

The whole house dehumidifier can operate stably for a long time to prevent moisture from affecting the walls and basement.

 

Usage recommendations

Optimal humidity setting: It is recommended to maintain it at 45%~55% in winter to avoid excessive humidity and dry air.

Pay attention to ventilation: The dehumidifier works better when combined with the fresh air system to avoid the accumulation of carbon dioxide.

Basement and crawl space: When the humidity is high in winter, the whole house dehumidification function effectively inhibits mold and condensation water.

Energy saving mode: Some whole house dehumidifiers support low-temperature operation and heat recovery, making them suitable for continuous use in winter.

 

Summary:

In the humid winter climate of Europe, whole house dehumidifiers not only reduce moisture and mold problems, but also improve heating efficiency and living comfort, making them important equipment for winter home health and house maintenance.
