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

We had the same problem. It improved a lot thanks to the enthalpy exchanger in the controlled residential ventilation system (in our case, Helios). Okay, now with -10°C (14°F) and extremely dry air, the humidifier is back in the living room. Otherwise, we usually have around 45%, currently without the humidifier about 35%.
