Hello everyone,
we are planning a single-family house with about 140 sqm (1507 sq ft) of living space and, like many here in the forum, we are undecided about the topic of residential ventilation.
Our architect and heating engineer have recommended the Schiedel ventilation system.
Does anyone here have experience with the Schiedel Area-Comfort and can share their insights?
Thank you very much

Well, it’s another decentralized system.
Holes are drilled into the walls through which fresh air flows in (cold in winter, warm in summer)... similar to trickle ventilation in window frames... meaning it can always feel a bit uncomfortable near the openings.
The exhaust fan then pulls the used, and in winter, hard-to-heat air out of the house... since ducts are also needed to reach all rooms, I don’t see any advantage compared to a central system, except probably the price... but since there is no heat recovery, the central system performs better again.
So why not just go straight for a proper central system?

I share Mycraft’s opinion. If a ventilation system is installed in a new building, it should be a central system with heat recovery.
Friends of ours have a system with fresh air intake from outside through ventilation bricks, and it is indeed the case that in winter, the side of the dining table facing the ventilation brick is usually less comfortable than the other side.
Another advantage of the central system, in my view, is the ability to filter the fresh air through a central filter. With the decentralized option, you either have several filters or, in some cases, none at all.
Best regards,
Dirk

Hello,
thank you for the initial assessments.
The heating engineer told us that the supply air valves operate automatically based on humidity and are set to a specific airflow that is not noticeable.
I would somewhat disregard heat recovery for now since we plan to heat with a groundwater heat pump and will also have a wood stove for winter; I could likely accept the disadvantages of operating without heat recovery.
We are basically discussing a price difference of about 5000 euros between a central and a decentralized system.

according to the manufacturer, the system is suitable for houses with a maximum living area of up to 140 sqm (1,507 sq ft). This means it is just about suitable for the house size you are planning.
I would definitely have the system demonstrated in a similar-sized building. As a layperson, I can imagine that a system constantly working at its performance limit might wear out faster (fans) and could also be noticeable in terms of noise at the corresponding speed.
Regards,
Dirk
