Correct heating and ventilation

Freezing for climate protection? That's certainly not the right way. Bring the rooms in your home to a comfortable temperature - but no more. Keep the heating level and room temperature as constant as possible and don't turn the heating up all the way. Constantly cooling down and heating up again is more expensive than maintaining an appropriate average temperature.

Depending on the room, different 
room temperatures are optimal:

For every degree you lower the room temperature, you can save 6% on heating costs!

At night, and even when you are not at home, you can lower the room temperature by about four degrees, but do not turn the heating off completely! This also applies to rooms that are rarely used. This is because if furniture and walls cool down, mold can easily form in combination with damp air. Room temperatures below 16 degrees should always be avoided.

Attention energy guzzlers: If your heating system "gurgles" or becomes unevenly warm, it needs to be vented. You can do this yourself with a ventilation key from the DIY store.

Correct ventilation for a good indoor climate!
Is that why you should always leave the window ajar? - This is a common misconception. This is because a large proportion of the rising warm air from the radiator escapes directly to the outside. Instead, you should get into the habit of opening the windows wide several times a day. You can turn the heating down slightly while airing the room. Short bursts of powerful ventilation will quickly replace the stale air in the room with fresh air without losing a lot of energy in the long term and cooling down the furniture and walls. If you have windows on both sides of the home, we recommend briefly "cross-ventilating" the rooms. This will also allow the moisture in the room air to be removed more quickly. If more moisture than usual is produced when showering, bathing or cooking, you should keep the doors closed and air the room immediately afterwards so that the water vapor does not condense on the cooler walls. Otherwise, mold can easily form.

You should ventilate three to four times a day at any time of year - the warmer it is outside, the longer.

If you have already carried out energy modernization measures such as insulation or window replacement, you should ventilate more frequently as air can no longer be exchanged through leaks. Nevertheless, you still save heating energy compared to old windows.
