Instead of a heat recovery ventilation you can use energy recovery ventilation which gets back some of the humidity, otherwise just buy a cheap electric boiling humidifier and it you get the job done.
What is important that in the coldest part of the winter you can turn down the ventilation to a minimal, something like 0.3 hourly exchanges per hour.

The problem is usually that the customer does not look into the details and the construction company can increase profits by buying cheaper versions. A good modern ventilation energy exchange unit for a 300m2 house can be <30dB, >90% efficiency, and return a lot of humidity.
