Hello everyone,
We will soon start an extension with the following rooms:
On the ground floor (GF)
Storage room 4.3m2 (46 sq ft)
Hallway 11.0m2 (118 sq ft)
Bedroom 17.6m2 (189 sq ft)
Shower 8.0m2 (86 sq ft)
On the upper floor (UF)
Living and kitchen area 38.0m2 (409 sq ft)
Pantry 1.7m2 (18 sq ft)
WC 1.7m2 (18 sq ft)
Ceiling height GF 2.37m (7 ft 9 in)
Ceiling height UF 2.45m (8 ft)
Wall construction 36.5cm (14 in) Poroton clay blocks
I would like to install a decentralized ventilation system in the bedroom and an exhaust fan in the shower.
On the upper floor, if possible, the living and kitchen area should be ventilated with one decentralized unit.
The WC should be equipped with an exhaust fan.
A central ventilation system is not an option due to the room height.
Is my approach feasible, or are there better concepts?
Which devices and manufacturers would you recommend?
Units with a cross-counterflow heat exchanger are preferred.
Noise level, air volume, and heat recovery should be appropriate for the respective rooms.
I would appreciate any advice and suggestions.
Best regards

I’m joining the discussion again. I’m currently renovating an older building and planning to install a decentralized ventilation system with heat recovery in the open kitchen/living room area.
The total area is about 57m2 (613 sq ft). Is it absolutely necessary to install two fans, preferably on opposite walls? Or is one sufficient?

I also use a simple exhaust system in my bathroom, as recommended by my energy consultant. He advises using the largest possible exhaust fan to quickly remove moisture.
I’m currently deciding which device to choose. In the shop mentioned, there is the RL50RVW with Wi-Fi or the Oxxify.smart 50, also with Wi-Fi. Would you still install a switch?

Is it actually necessary to use two fans? If you want a ventilation system with heat recovery, one fan is not enough. One fan can only exhaust air. Fresh air then comes in (without preheating) through trickle vents in the window frame.Deliverer schrieb:
