I have a large (95 sq meters) undercover area behind my house:
A few things to note:
- The house is just to the left of the picture.
- The roof of this area slants from the house to the far wall (as you would expect)
- There is a barbecue just outside the photo to the right
- Even further to the right, fairly close to the bbq, is a clothesline for hanging clothes
When I am cooking on the barbecue, the area can get quite smoky, as you would expect. The smoke even gets in the house quite a lot if I leave the doors open. I'm thinking of installing a vent in the roof, but I am not sure where or what kind of vent to get.
Location of the vent
There are three options that I see.
- Directly above the bbq, the most obvious option
- In the middle of the area (both axes)
- Against the house, but in the middle on the other axis
What if I want to move the bbq one day? If I put the vent right above the bbq, then it will be at the lowest point in the roof, so I feel like I will get smoke trapped against the house as it rises due to the slant in the roof. Are there any other gases besides bbq smoke that I might want to extract? This area is not currently accessible with a vehicle but I would like to make it accessible one day. I am a brand new homeowner so haven't any experience in this regard.
Type of vent
A few options here...
- Turbine vent
- Powered exhaust fan with an actual switch
- Regular house fan that I can move around and isn't installed in the roof
Do I want to be able to turn it on and off? A turbine vent is not powered, correct? So it is always on? Or at least when there is wind blowing. Maybe this isn't necessary and I only need a regular fan to keep the air moving?
