Hello

I have built a new house (6 months) in one story, 170 sqm, and I have a question about ventilation (supply and exhaust air via gap vents in the windows). The air feels a bit stuffy when you enter the hallway, and cooking smells and other odors can take time to disappear. We have an open floor plan, but is it supposed to be like this? OVK has been measured and is correct, and all vents are open.
 
You don't have both supply and exhaust air in the slot vents, do you? You must have some form of mechanical exhaust air in a new building. Is it an exhaust air heat pump or what handles the mechanical exhaust air?
 
No, not both. Yep, exhaust air pump.

If you have a fireplace, open the damper. Otherwise, refer to the previous answer.
 
Increase the speed of the pump for a few days and see if it improves.
 
The air is according to the flow of the drawings. Should one change these?

I am closing the damper for the kakelugn according to the instructions. Why leave it open?
 
R
so that you get some natural ventilation, the house is most likely built for partial natural ventilation. If I were you, I would try it for a week and see if there is any difference.
 
Call the company that installed the system instead. Creating natural ventilation via the chimney is against the recommendations I received from my installer.

ok so the house wasn't built with the stove from the start then. yeah if you don't try natural draft, you might as well look at mechanical ventilation then. you didn't need to ask if everything is already done
 
The stove is included from the start. I was wondering if houses might feel heavier in the air when they are new?

The house is definitely not built with natural ventilation if it is 6 months old.

Talk to the project manager or the ventilation company. It might be that the minimum flow rates they outline according to some table simply aren't enough. A problem with modern house construction is that the need to be incredibly energy efficient can affect comfort.
 
Okay, so maybe we need to increase the draft through the exhaust air? Won't there be extra draft if I open the damper in the tiled stove?

Well, it's not possible to answer without knowing how your ventilation is adjusted. It might be possible, but it could also result in poorer ventilation in other rooms because the pressure conditions will be completely different.

In most slightly more advanced cases where there is mechanical ventilation, there is a compensation mechanism specifically for wood-burning stoves to reduce the impact on other ventilation.
 
Just to test with the kamin then?
 
Just try to increase the fan on the exhaust air pump. A Nibe 750 should be around 60% for 170 sqm, so try increasing to 75 and see if it gets better. Just increase that and do not adjust the plates as you need to calibrate them with an instrument.
