Hello everyone, the title already describes the problem. Approximately 20% humidity in all living and sleeping rooms. We moved in about two weeks ago. That can’t be normal, right? I expected such low humidity only after 2-3 years, but not right from the start...
The first night in the house was really horrible. On top of that, we have been dealing with colds and coughing the whole time. We now have a humidifier running all night in the bedroom (starting in the evening, about 12 hours total) and wake up with around 35-40% humidity.
Could something be set incorrectly in the mechanical ventilation system with heat recovery, or is this low humidity normal in a new house?
What can we do? Apart from the bedroom, we don’t notice it being a problem in any other room. Enthalpy exchangers are supposed to increase humidity by a maximum of 5%, right?!
Thanks for your feedback and best regards

Do you also have a 40+ year-old house?
How long have you been living in it?
On the ground floor, we have tiles everywhere, and in the bedrooms/kids’ rooms, we have engineered flooring.
So far, two orchids have somehow found their way here :-)
I guess we’ll just wait until the next winter and see how it goes. Humidity is only around 30% in the open-plan living area, where it isn’t unpleasant, but it’s noticeable in the bedroom.

Stefan0013 Mar 2023 10:13If you don’t have any issues with humidity or stale air, simply reduce the operating time (and volume) of the mechanical ventilation system.
For example, in our case, it now runs less than 50% of the time, and only at the lowest setting.

What about the enthalpy exchanger from the very beginning? Sure.

For us, it doesn't even run at the lowest setting more than 50% of the time. Do you mean it’s off more than 50% of the time and runs the rest at the lowest setting?
I wouldn’t switch off a central mechanical ventilation with heat recovery.
And turning it down only to ventilate manually later usually makes things worse rather than better.

Turning off the mechanical ventilation system is certainly not the intention behind its design...
