Since my roof has recently been upgraded and is now basically airtight, I’m considering installing a ventilation system for the top-floor apartment. Especially since I’m sometimes away for 1-2 weeks and tilted windows are not always rainproof. However, I lack basic information on this topic.
My considerations:
Is it possible to have forced ventilation in individual rooms when humidity levels get too high?
-> Bathroom, insulated attic, office, bedroom, living-dining room including kitchen
-> Can such a system be effectively operated if a wood-burning stove (Swedish stove) is installed in one of the rooms, or is that a fundamental problem?
-> Can such a system, for example, extract warm (too warm) air from one room and distribute it to other rooms as heating support?
-> Are the airflow or ventilation noises noticeable or audible?
-> Can the system be installed in the attic? Would that cause excessive noise in the bedroom below? (The attic is insulated on the roof side, so there is no insulation between the attic and the rooms below.)
-> Can a system like this help save heating costs?
-> Does the system redistribute air considered too humid in some rooms to others where the air is too dry, or is it always vented outside?
-> Is such a system intended to run continuously or only 2, 3,... 6 times a day?
-> Is operation controlled by humidity alone or by both temperature and humidity?
-> I often read that mold growth inside the system is dangerous. How realistic is it that such a system actually develops mold? What and how often does maintenance or cleaning need to be done?
The apartment is about 95m² (1,022 sq ft) with an average ceiling height of 3.2m (10.5 ft). Roughly 300m³ (10,600 cu ft) volume (unfurnished). The layout is as follows:
Living-dining-kitchen (open plan) 55m² (592 sq ft) / 187m³ (6,600 cu ft)
Bathroom 10m² (108 sq ft) / 34m³ (1,200 cu ft)
Bedroom 14m² (151 sq ft) / 28m³ (990 cu ft)
Hallway 10m² (108 sq ft) / 35m³ (1,230 cu ft)
Office 6m² (65 sq ft) / 12m³ (420 cu ft)
Does it make sense to connect radiator thermostats directly to this ventilation system to control temperature and humidity centrally throughout the apartment? Would that be considered a basic package or already a premium standard?
For my bathroom, I’ve already acquired an exhaust duct including a fan. The duct has a diameter of 100mm (4 inches). Could this be used as the ventilation duct so that I don’t need to make another wall penetration?
What are the basic requirements such a system must meet, and what features are optional extras? I assume connecting to the heating system would be more of a bonus and would involve higher costs.
Is it possible to estimate what such a system would cost for an apartment like mine?

These are pipes that blow air into the room and others that extract it.
Of course, you can come up with a control system and have it implemented... but whether it will ever work as expected? I doubt it. Connecting the rooms together is also rather unusual.
In existing buildings, you would need to work with boxed-in ducts or suspended ceilings... or just go with decentralized systems.
When it comes to preserving the building fabric, such a simple, straightforward decentralized system is actually great... it always runs at setting 1, and when you leave, you can switch it to setting 2.

garfunkel25 Sep 2016 20:38Basically, I have a few key points I would like such a system to fulfill.
- Forced ventilation when the humidity is too high (not only in the bathroom)
- Extracting excess heat, for example from the wood stove, that accumulates near the ceiling and directing it to rooms like the bedroom, hallway, or office
- Fresh air supply
The most important thing is that the moisture is removed. The roof has been renovated to the KW50 standard, and I only have a few square meters of gable wall as exterior walls. Otherwise, there are no old exterior walls left in the attic apartment, or no additional exterior walls at all. So the entire apartment is somewhere between KW50 and KW70.
To me, distributing excess heat also seems useful, especially with a ceiling height of over 3m (10 feet), as a way to support heating.
I don't really know offhand how many ducts I would need to install. I guess it depends on where it makes sense to extract and redistribute the warm air. Since there is still an attic space in some parts, I imagine that in my case this won’t be too complicated, at least in terms of hiding the ducts. If everything goes well, I would only need to cut a few ventilation holes in the room walls and could route and conceal all the ducts in the attic. However, I’m not sure if it will work out as I imagine.
Basically, I would need a device that can either intake fresh air from outside and distribute it throughout the apartment, or extract room air and either exhaust it outside or redirect it to another room if needed.
I have no idea how expensive something like this might be, whether it’s a standard solution or a custom build. Still, I find the idea of controlling a whole apartment’s air that way quite interesting.
It would also be interesting to be able to tell the radiators that they no longer need to heat, or can reduce their output, because warm air is being supplied from another room.

garfunkel25 Sep 2016 20:53Yes, sure, but can you estimate how much a system like the one I described would roughly cost?
So, warm air distribution to other rooms,
fresh air supply,
ventilation in case of high humidity.
Which specialist usually handles this? Are these heating engineers, or should you go somewhere else in this case?
