I’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?

We decided to build a DIY ground heat exchanger. My friend, who also did the earthworks, installed a 200mm (8 inch) KG2000 pipe at about 2.5m (8 feet) depth around the house in the excavation pit. It’s roughly 40 meters (130 feet) long.
This serves as the supply air duct and works like a ground heat exchanger. It added about 800€ to the cost of the earthworks.
I’m aware that some people are skeptical about this kind of solution (condensation inside the pipe). However, I trust my friend as an experienced sewer contractor. He says the pipe is laid with approximately 2% slope so that no water can accumulate anywhere inside.
