Correct heating and ventilation in rented apartments.

A pleasant and healthy living climate is crucial for our well-being. The right balance between heating and ventilation plays a key role in this. Here you can find out how to avoid mold, create the right balance between room temperature and humidity and thus create an ideal living climate.

Preventing mold growth and creating a healthy indoor climate

Mold is not only unattractive to look at, but can also cause health problems. To prevent mold growth, it is important to keep indoor humidity levels low.

Here are some tips:

  • Regular ventilation: To remove excess moisture from your rooms, ventilate regularly. Instead of permanently tilting windows, ventilate several times a day, even in winter. This helps to exchange the air without losing too much heat. Opening opposite windows or doors creates an efficient air flow that ensures rapid ventilation. Pay attention to the time of day: the air is often fresher in the morning and evening. Use these times for ventilation.
  • Avoid excessive heating: An excessive temperature difference between inside and outside can lead to condensation problems. Keep the room temperature constant at a comfortable medium level.
  • Heat even rooms that are not used much: Avoid cooling rooms in your home completely. Even slight heating of rooms that are rarely used helps to prevent this. Temperature differences of more than 5 degrees between rooms within the home can quickly lead to a mold problem, for example if warm, humid air from a living room enters cooler rooms and condenses on the walls.

The relationship between room temperature and humidity

The right balance is crucial for a comfortable indoor climate:

  • Optimal room temperature: The ideal room temperature is usually between 18°C and 22°C.
    This can vary depending on personal preference, but try not to overheat and you will also save energy.
  • Control the humidity: A relative humidity of 40% to 60% is ideal indoors.
    Humidity monitoring meters are inexpensive and help you maintain the right level. In a well-insulated building, a value of around 60 percent in the home may not cause any problems for some time, but if the building is poorly insulated, 40 percent at the thermal bridges and in the corners of the room can be too much on cold days. If the humidity is above 50 percent for a longer period of time, ventilation should be provided – at the latest when the window panes mist up from the inside!

A healthy indoor climate, mold prevention and the right balance of room temperature and humidity are crucial for your well-being within your own four walls. By following these tips, you can not only save energy, but also ensure that your home remains a place of well-being.
