Ventomaxx How to Ventilate in winter

In winter, it is particularly difficult to air rooms: cold air outside and heating costs inside are arguments that persuade many people to leave the windows closed. However, proper ventilation is just as important in this season as in any other. Those who want a healthy indoor climate, want to avoid mould and save energy in their own four walls should choose the right ventilation technology. Decentralised ventilation systems offer a clever solution to these challenges. In this article, you will learn why ventilation is crucial in winter, how to do it right, and what advantages decentralised ventilation systems offer.

Why is ventilation so important in winter?

In winter, proper ventilation is particularly important to ensure a healthy indoor climate and maintain air quality within your own four walls. During the cold season, many people tend to keep their windows closed to save heating energy. However, this can lead to an accumulation of moisture, pollutants and bacteria in the air. Especially in well-insulated buildings, regular ventilation is essential to reduce these contaminants and create a pleasant living environment. The challenge of ventilation in winter Regular ventilation is essential for our health and living comfort. It reduces the concentration of pollutants, regulates humidity and prevents mould growth. However, especially in winter, when temperatures drop and heating systems are running at full blast, efficient ventilation becomes a balancing act between the need for fresh air and energy efficiency. Basics of ventilation in the cold season Unlike in summer, when a light breeze is often enough, ventilation in winter requires a more targeted approach. The main objective is to exchange the humid, stale air inside for dry, fresh air from outside. This is particularly important because warm air can absorb more moisture, which can lead to condensation when it cools down and to mould forming over time. Airing your home in winter not only allows you to exchange stale air for fresh air from outside, but also helps to regulate humidity. Regularly airing your home in short, sharp bursts removes excess moisture, reducing the risk of moisture damage to walls and furniture. A well-ventilated home in winter not only ensures your well-being, but can also help to prevent mould and contribute to an overall healthier living situation.

Tips for manual ventilation in the cold months

When it’s cold outside, many people neglect to air their homes for fear of losing the expensive heated air. However, it is important to understand that regular ventilation is crucial for health, indoor climate and energy efficiency even in winter. Here are some important tips on how to ventilate properly even when the temperatures outside drop:

Ventilate intermittently: Open all the windows wide for a few minutes several times a day to ensure effective air exchange. This reduces humidity and prevents mould formation.
Pay attention to the right time of day: Ideally, ventilate in the morning and evening when the air outside is freshest. Avoid long ventilation periods in the late evening hours.
Cross-ventilation: To effectively change the air in the room, open windows on opposite sides of the room. This creates a draught that ensures optimal ventilation.
Combine heating and ventilation: Turn up the heating briefly before ventilating to warm the air in the room. This means that the room cools down less when ventilated and heating costs do not rise excessively.
Ventilate even when it’s cold outside: Despite low temperatures, it is important to ventilate regularly to remove stale air from rooms. Even short bursts of ventilation are effective and help to save energy.
Close windows properly: Make sure that windows are closed properly after ventilation to avoid energy loss.

Special challenges of manual ventilation Manual ventilation brings with it a number of challenges:

In the kitchen and bathroom, ventilation is needed more often to dissipate moisture.
In the bedroom, regular ventilation is important but often difficult to implement, especially at night.
When you are away, you cannot ventilate, which can lead to air quality problems.
Drafts and cooling can occur if ventilation is not done properly.

Common mistakes when ventilating in winter

In the cold winter months, proper ventilation is particularly important to ensure that rooms are supplied with fresh air while maintaining a comfortable indoor climate. Unfortunately, however, mistakes are often made when ventilating during this season, which can lead to unnecessary energy loss and inadequate ventilation. One common mistake is to air rooms intermittently and irregularly. People often tend to open the windows only briefly instead of airing them for a longer period of time. This does not allow for sufficient air exchange, which can lead to poor indoor air quality. Furthermore, people often forget to turn off the heating while they air the rooms. This results in hot air being released into the open air unused, causing heating costs to rise unnecessarily. Effective ventilation should therefore always be combined with turning off the heating. Often, the various rooms in the house are not ventilated individually. It is important to note that each room has different ventilation requirements, e.g. due to the use of the room or mould prevention. Another mistake is to ventilate by tilting the window. Tilted windows do not adequately exchange the air in the room and the surfaces of the windows can quickly cool down, which in turn can lead to mould growth. Many people also forget to ventilate unheated rooms such as basements or attics. These rooms are particularly prone to moisture build-up and mould problems. Decentralised ventilation systems offer a simple solution here. They ensure a constant supply of fresh air, prevent mould growth and reduce heating costs without having to open the window.

Optimal ventilation intervals

Experts recommend intermittent ventilation several times a day during the winter months. You should open the windows wide for about 5-10 minutes to ensure effective air exchange. By ventilating in intervals, you can keep humidity at an optimal level while improving indoor air quality. It is advisable to air briefly, especially in the morning and evening, to let fresh air into the room while keeping the heat inside. By ventilating at specific times of the day, you can ensure that you benefit from both health and energy-saving advantages. The recommended frequency of ventilation varies depending on how the room is used and how many people are in it. As a rule of thumb,

living rooms: 3-4 times a day
bedrooms: 10-15 minutes in the morning after getting up
kitchens and bathrooms: 5-10 minutes after use

The length of time you air should be adjusted depending on the outside temperature:

At minus degrees: 2-3 minutes
At 0-5°C: 5 minutes
At 5-10°C: 5-10 minutes
At 10-15°C: 10-15 minutes

However, remember to ventilate regularly even at cold temperatures to prevent mould growth and create a pleasant indoor climate. By adhering to optimal ventilation intervals, you can not only improve air quality, but also help make your rooms feel comfortable.

Decentralised ventilation systems: the modern solution for efficient ventilation

Decentralised ventilation systems are one of the most advanced solutions for efficiently supplying your home with fresh air. In winter, controlled ventilation plays a crucial role in ensuring a healthy indoor climate while saving energy. These modern systems offer a variety of advantages that outshine traditional ventilation methods. The decentralised ventilation systems work quietly and unobtrusively in the background, without detracting from the look of your rooms. They ensure a constant exchange of air, which both improves air quality and reduces the formation of mould in the damp winter months. Thanks to their efficient heat recovery, you can save on heating costs while still maintaining a comfortable indoor climate. Another advantage of decentralised ventilation systems is their flexible installation. They can be easily placed in individual rooms, which enables targeted ventilation. This allows you to provide fresh air in rooms with increased humidity needs or in heavily used areas. The modern technology behind decentralised ventilation systems also offers demand-based control. This allows you to adjust the ventilation according to room use and individual needs. This leads to an efficient use of energy and ensures a continuous supply of fresh air. Overall, decentralised ventilation systems are the ideal solution for efficient ventilation in winter. They combine comfort, energy efficiency and health, and offer a modern alternative to conventional ventilation methods.
