Living room humidity 30-40%

Timber frame house?

They have 25% humidity and timber frame house with comfort climate heating. Is that something specific to timber frame houses?

We have the same problem. With humidifiers, you have to pay attention to the size of the room. We have a small one that hardly seems to help. We also have one from Venta. My tip: eBay Kleinanzeigen. There are definitely good offers there in your area as well.
Additionally, there are certain plants that improve the air. We have also gotten some of those. You can spray them regularly, it also says so on the packaging. If you want, I can go check what kind of plant it is.

No, that is something specific to the comfort climate heating systems. The name is just the name here.

No, that is something specific to the Wohlfühlklimaheizungen. The name here is just the name.

Okay, that surprises me so much. They are actually installed so often...

But that is due to the good marketing department and other things. However, not the product.

Do you have a ventilation system in the house? With well-insulated and energy-efficient timber frame construction, it is actually a MUST! If not, congratulations anyway! 30 to 40% indoor humidity is actually good for this. Over 50% is not necessary and already feels "stuffy" again. You just have to make sure that the values do not permanently fall below 30%. To avoid this: - no tilt window ventilation (energetically nonsense anyway) - shock ventilation in the morning (cross ventilation) for about 15 to 20 minutes. Then close everything. - Kitchen exhaust hood? Set it to a higher level while cooking and open the kitchen window during this time for inflow. - In the evening before bedtime, shock ventilate again for 10 to 15 minutes. Too much ventilation in dry weather (especially with cold air) brings dry air into the house, which then becomes even drier with heating.
