Hello everyone,
Since my explanation has become a bit longer, I will put the actual question first. Is it basically possible to realize a central residential ventilation system using an unused chimney flue (supply air) and an exhaust flue? Or is that not possible and new pipes would have to be installed to distribute the air over the four inhabited floors.
My fiancée and I bought a partially renovated old terraced house from 1928 in the summer.
At that time we had not thought much about residential ventilation, but we will soon be renewing the electrical system and will have to open up a lot anyway, so now might be the right time.
We would possibly leave the planning to a professional, but before that I would like to roughly estimate how such a system could be realized and how big the actual effort would be. The manufacturers' schemes mostly refer only to new buildings and certainly not to terraced houses that extend over four inhabited floors. If there are experiences with competent work in the Bremen area, I would also be grateful for that, as long as it does not contradict the forum rules (I did not find anything on this quickly).
There is already an exhaust duct that was installed by one of the previous owners and runs through all floors, which might still be used for the exhaust air. In the basement there is already a kitchen (active via extractor hood), laundry room and WC (passive), on the ground floor the guest WC (passive), on the first floor the bathroom (active via fan) and in the attic the guest bathroom is connected passively. The "ventilation pipe" in the attic looks like a 120 mm HT pipe to me. So ultimately all typical exhaust rooms are connected to it.
In the basement there are actually no classic supply air rooms, but air exchange with the other floors would be possible via the open staircase. On the ground floor these would be the living room, on the first floor the bedroom and TV room, and in the attic the guest room. Two chimney shafts run through each of these rooms, which are not used and could possibly be used for distributing the supply air.
Both could be tapped in the (insulated with 120 mm mineral wool) attic.
If you need more information, I will happily provide it, although as mentioned, it is primarily about the basic feasibility.
Best regards and many thanks in advance,
Tobias
