ᐅ Humidity has dropped dramatically

Hello everyone!

We have now been living in our new house for 14 months and are very satisfied. There is always a lot to do, both inside and outside. However, we have been concerned about the humidity levels in the house for some time.

We had a prefabricated timber frame house built, KFW 55 standard. We also use an air-to-water heat pump from Tecalor with a ventilation system that includes heat recovery. The humidity has dropped to below 20% during winter. As far as we know, the indoor humidity should be between 40% and 60%, partly for the sake of the mucous membranes and overall comfort. According to the technician, we cannot adjust anything further on the heat pump regarding this.

Is using a room humidifier our only option now, or does anyone have other suggestions?

Best regards,
SaRo

My wife just looked up these enthalpy heat exchangers and said that we have ones like that in the pump. She saw them when the pump was serviced. Okay, now we will get a humidifier and see if it works well.

There is now no real visible difference between a standard heat exchanger and an enthalpy heat exchanger. I would recommend checking what is inside.

Alright, we will inquire about that. Thank you!

As far as I know, the Tecalor THZ units, just like the Stiebel Eltron LWZ devices, always come with a cross-flow heat exchanger as standard. And as halmi already mentioned, if you don’t specifically look into it, you won’t notice any visual difference.

The difference is really hardly noticeable. At first and even second glance, they look the same.
If the humidity is that low, I assume you don’t have any.

For this exact reason, we chose a central ventilation system from "Hoval." As far as I know, it is the only one where you can adjust the humidity level, with a control range between 30% and 65%. We set it to 50%, and it is maintained within plus or minus 1%. This makes the air very comfortable at all times.
