ᐅ Extremely dry air caused by ventilation heating – what can we do?

Hello,
I hope someone can offer us some advice.
In 2010, we built a Weberhaus using the so-called Wohlfühlwärmetechnik (comfort heating technology). This involves a Proxxon ventilation heating system with heat recovery from Zimmermann.
Every winter, we have the problem that the indoor air becomes extremely dry. And by extremely, I do not exaggerate. The colder the outside temperature, the drier the air inside. Measurements show humidity levels between 25-35 percent.
As a result, we all suffer from respiratory issues during the winter, to varying degrees. This is especially difficult for the children.
Neither Weberhaus nor Zimmermann have been able to help us with this problem.
Is there anyone here who has had a similar experience and/or a solution?
Are there modules or systems that can be installed to humidify the air?
Regards,
joela

My personal opinion on this topic is: Either a Passive House (which, when considering total costs, becomes cheaper after just a few years and is significantly more environmentally friendly) or underfloor heating combined with an air-to-water heat pump (or ground-source heat pump in very cold regions).I am planning to build a KfW40+ house, which is very close to a Passive House standard, and I am wondering whether it's worth taking the risk with this technology since it is difficult to change later. Proxon pumps are designed for this... So, in that case, would you not recommend or choose underfloor heating?
Our house performs significantly better than KfW40 but is still not as efficient as a passive house. Of course, suppliers tend to present this more positively because they are cheaper with LLWP (not because the heating is cheaper, but because ventilation is no longer required). Discuss this with your energy consultant.
I believe @haydee has a passive house and can share some insights on that as well as on the preferred heating system.

Who nowadays still has a problem with dry indoor air during winter?
You were probably there for only one or two hours. I think drawing conclusions from that is incorrect. Besides, you don’t know if there was a humidifier in the corner or a system with humidity recovery installed. The fact is that many people do have problems with dry air during winter.

I recently attended a consultation at a show home with an air-to-air heat pump, and despite wearing contact lenses, I didn’t experience dry eyes.

Or basically the same price for a passive house if you find someone to build it for you. Then you wouldn’t really need a conventional heating system.
Both require a central ventilation system.

(not because the heating is cheaper, but because the ventilation is omitted)No. The water part in the floor is omitted. Both have ventilation.Deliverer schrieb:
No. The water part in the ground is eliminated. Both have ventilation.Oh, I confused myself because with an air-to-water heat pump you also need a controlled residential ventilation system... but of course you are right.
