Humidity has dropped dramatically

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

There is now no real optical difference between a normal heat exchanger and an enthalpy heat exchanger. I would check what is inside.

Ok then we'll ask there. Thanks!

As far as I know, the Tecalor THZ, just like the Stiebel Eltron LWZ devices, always have a cross-flow heat exchanger installed as standard. And as halmi already wrote, if you are not dealing with it specifically, you don’t see any difference visually.

You can hardly tell the difference. At first and even second glance, they look the same. If the humidity is that low, I guess you don't have any

We decided exactly for this reason on a central ventilation system from "Hoval". As far as I know, it is the only one where you can set the humidity. Regulation between 30% - 65%. We set it to 50% and it is maintained within ±1%. This way it is always very comfortable.
