junge_familie13 Feb 2018 16:38I’m torn when it comes to the topic of mechanical ventilation with heat recovery. My wife is very skeptical; partly because she worries about drafts (she is quite sensitive to that) and also (and I partly agree with her here) because of concerns that mold or similar could eventually build up inside the extensive ductwork.
1) Does anyone here have long-term experience with mechanical ventilation with heat recovery? At least around 10 years?
2) What are established or reliable brands that you would recommend? Are there any manufacturers you would advise avoiding?
3) What should you pay attention to (manufacturers, building-specific details, etc.) if it is important to avoid feeling any airflow?

Where is the mold supposed to come from?
If it gets into the duct, you have completely different problems in the house.
Often mentioned brand is Zehnder.
The system needs to be planned. This is done by the manufacturers. Drafts are usually related to vents located close to seating areas or when transfer air paths through doors or frames are not properly sized. But none of this is rocket science, it just needs to be considered.
Without ventilation, I would be far more concerned about mold. The necessary manual ventilation is almost impossible for anyone who isn’t home all day. In my opinion, some kind of ventilation system is needed, even if it is a simple supply air with an exhaust fan.

1. 6 by now
2. Zehnder, Helios, Wolf, Vallox, etc. basically don’t matter much; 90% of these systems are made from the same materials, and the differences usually come down to the price of consumables and the control options.
3. The system has an enthalpy exchanger. Airflow? Where is that supposed to come from?

Due to the airtight construction, a controlled mechanical ventilation system is highly recommended to prevent mold in the house. Another advantage is the fine dust/pollen filters and the constant air exchange, so you can keep the bedroom windows closed if it is too noisy outside. My system has been running continuously for almost five years.
The heat recovery feature means there is almost no energy loss.
Proper professional planning is essential, and you should not skip the exhaust air filters in the living areas. Maintenance is also very easy, even for non-professionals.
