ᐅ Exhaust duct for range hood through the wall or through the ceiling and roof?

Hello,

For a range hood (exhaust) duct, is it better to vent directly through the wall or through the ceiling and roof using a roof vent? I think venting through the wall is simpler and less expensive, but which option is better?

(Bungalow, attic not insulated, no attic conversion planned, carport located behind the exterior kitchen wall)

Regards

Where your cooktop is located, the solution with a roof vent is probably "better."

This way, you can use a range hood with an external fan installed in the attic. It’s very quiet; I had this setup in my last house with a Miele extractor hood. You will also need a condensate trap.

A kitchen installer said that in the roof ventilation solution, a condensate container should be installed in between, and the condensate evaporates on its own. With a condensate trap, the condensate has to be drained somewhere, right? Usually, does the kitchen installer handle everything?

I don’t think there is a hard rule for that. The roof work should be done by a roofer. A drainage solution for the condensate should be considered by the plumber.

The condensate trap mainly just prevents water from flowing back into the motor. What happens to the water afterward is a different matter. I’m not a fan of evaporation. How is that supposed to work in winter, when most condensate forms but nothing evaporates, and it’s more likely to freeze?

If it fits, I will install the exhaust vent through the wall (there is no 150mm (6 inch) ventilation sleeve available).

We will build the carport later, but it is already included in the plans so that it aligns with the roof overhang of the house from above. If the wall opening for the range hood exhaust turns out to be too tight, it can be worked out and adjusted somehow, but I would prefer to avoid custom sizes. How high are carports with storage rooms usually?

Can anyone estimate roughly how much space I will have between the floor and the roof overhang afterward?
