Warmth and fresh air
Save heating costs with ventilation
Why ventilate in winter?
Shock ventilation instead of tilting
If you are out all day, it is sufficient to air the apartment in the morning and in the evening. Otherwise, for hygienic reasons, it is recommended to completely exchange the air at least three to four times a day. You should always ventilate the kitchen and bathroom when large amounts of water vapor have formed – zum Example after cooking or bathing.
Maintain the optimal room temperatures
Just one degree Celsius less saves around 5% on heating costs. Therefore, the living rooms should be heated according to their purpose. 18 degrees Celsius are sufficient in the hallway, bedroom and kitchen. At 20 degrees, the living area and study have the optimal temperature. In the children’s room and bathroom it can also be a little warmer at 22 degrees Celsius. Thermostats help them to keep the right temperature.
Make sure that unused rooms are kept at a minimum temperature of 14 degrees and that the doors of heated rooms remain closed to prevent mold growth.
Pay attention to free radiators
Do not place any furniture in front of the radiators so that the warm air can be optimally distributed in the room. Also, do not put wet clothes on the radiator. It is better to dry your laundry on a drying rack.
Bleed your radiator so that unnecessary air escapes and the radiator can heat up to the set temperature faster. All you need is a radiator key, a container to collect the heating water and a rag.
Turn down heating instead of turning off
Don’t turn the heating off completely overnight or when you’re away, as it’s more expensive to reheat a cool room. Better keep the average temperature lowered to 16-18 degrees Celsius and turn the heating down.
Energy-efficient ventilation and lower heating costs
Decentralized ventilation systems with heat recovery ensure continuous fresh air indoors and can reuse up to 94% of the exhaust air heat with the ceramic heat accumulator. The ceramic core stores the heat of the interior air when exchanging the used air and gives it off to the fresh air flowing in from the outside. As a rule, the living room air is completely exchanged every 2 hours. The strength of the ventilation adapts to the individual needs of the residents.
You can get fresh and warm air into your rooms without having to open the window all the time.
Why is a decentralized ventilation system with heat recovery worthwhile?
Frequently asked questions about ventilation and heating
Why does ventilation save on heating costs?
In contrast to tilted windows, intermittent ventilation saves energy and at the same time helps to prevent mold growth.
How do you save the most heating costs?
Through a good balance between ventilation and heating. Regular airing is best instead of leaving the windows open all the time. Furthermore, the heating should not be switched off completely at night and when you are away, but only turned down.
What happens if rooms are not heated?
Mold can quickly form in rooms that are never properly heated. Moisture can get into the permanently cold room through open doors of heated rooms and thus condense the moisture on the cold walls.
