ᐅ Controlled residential ventilation Dry air – are humidifiers the right solution?

Hello,

We have a great controlled residential ventilation system from Zehnder ComfoAir Q450 and are very satisfied with it. In winter, we set the ventilation rate to level 1 (reduced). Currently, the rooms have about 35% relative humidity. In the living room, especially with the use of the tile stove, it sometimes drops below 30%. What should we do?

We are considering installing a humidifier in the living room (just under 60m² (645 sq ft)).

Do you have any tips regarding this? Especially concerning generally low indoor humidity?

Best regards,
Barossi

The system can be upgraded with an enthalpy heat exchanger that recovers moisture. Just try searching for "400502010". However, it already costs around €900.

But it is the only proper solution; you shouldn’t start with a humidifier.

Hello,

Perfect! €900 is not exactly a bargain, but in the long run, it's the best option.

Can a private individual replace it themselves?

Best regards, Barossi

Yes, of course...

We installed a Zehnder Q350 with an enthalpy exchanger.

I am just starting to familiarize myself with the device; yesterday I installed the KNX module and began configuring it.
Even so, it’s already clear—and what we also feel—that dry air should not be an issue.

Simply very comfortable, I’m glad I insisted on the enthalpy exchanger.
