Hello everyone,
how is it with your mechanical ventilation system with heat recovery? At the moment, we have a humidity level of 30 - 32% and unfortunately, that’s not very comfortable. Is it the same for you?
We have a Vallox system with heat recovery, and there is an option to upgrade to an enthalpy heat exchanger. However, that costs around €1000 and I’m not sure if it really makes a difference.
Right now, I’m quite disappointed with the mechanical ventilation system. In winter, the air is dry, and in summer, during the heat, you don’t get fresh air into the house either.
I’d like to hear about your experiences.

Heating less also helps – but that feels a bit old-fashioned.

Hmm actually nothing A membrane is definitely more expensive than a piece of sheet metal. I think it’s quite reasonable to offer a standard heat exchanger at a lower price than one that allows water vapor to pass through using a membrane. Conversely, the enthalpy heat exchanger option must be more expensive. The exact figures can be debated, of course.
