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

Yes, such devices exist and are called enthalpy or rotary heat exchangers. However, you should check whether they are compatible with your ventilation heating system. The easiest way to find out is by contacting the manufacturer. The cost, including installation, is around 1000 €.

Otherwise, many large plants and humidifiers can help everywhere...

Zimmermann fundamentally offers different systems! On the other hand, this problem is not new and has increased in single-family homes with the use of controlled residential ventilation systems. Simple, uncomfortable, and non-adjustable solutions include decentralized evaporation containers, humidifiers, or indoor fountains from hardware stores.

While this is almost standard in industrial and commercial settings, smaller units lack this feature range. However, retrofit options do exist. For this, there must be a central fresh air duct after the ventilation unit before the branch distribution begins. Whether there is enough space for this, as always, depends on the individual case.

Best regards.

Hello Joela,

Through your above post, we learned that your house is heated using a ventilation heating system.

We are a young project team working for Bosch Thermotechnology GmbH, examining the advantages and disadvantages of ventilation-based heating.

You have likely gained some experience in this area. Would you be willing to share it with us?

You can decide the extent and method of information exchange (email, phone, face-to-face, etc.). We look forward to your response!

Best regards

Only 1 post in 2014 and nothing else... I have very little hope.

Highly unlikely that the user will respond. But there are surely others here who use this controversial heating technology.
