ᐅ Fireplace Stove External Air Supply – What Is the Best Technology for It?

Does anyone have information about supplying outside air to a wood stove?
Of course, there need to be some kind of shut-off options so that cold outside air (in winter) does not enter the rooms uncontrollably. I imagine there are different solutions for this (automatic, electric, manual). So far, my search has found few images and very little information on the subject.
What does the access on the exterior of the house look like? What sizes can the supply duct have (minimum diameter)?
We are converting our attic and are currently planning to buy a new stove, but which one it will be is still completely undecided. That’s why I want to make the outside air supply possible, even if it might not be needed.
Honestly, I don’t know exactly when this setup makes sense and when it doesn’t.
1. When using a range hood (cooker hood).
2. When windows and doors are so well sealed that little or no air flows in.
Are there any other advantages to using outside air for a wood stove if these two points do not apply? Or are there disadvantages? Somewhere I read that rust can form inside the stove because of moisture.

I think we currently have enough “new” electronics in/on the house ... (photovoltaic system and electric car) 😀 It’s an electronic system that doesn’t require any attention, especially since manual operation is still possible in case of a failure. For a wood stove, you can probably skip it. Our masonry heater is the main heating system and is in daily use now, so it’s a different matter.

pagoni20202 Dec 2021 21:32Our wood stove will also operate without external air supply. Since we have a mechanical ventilation system with heat recovery, the chimney inspector said that a pressure monitor needs to be installed. Unfortunately, this costs 750 (units), but it is required by him due to the mechanical ventilation system.
In our previous house, we used a wood stove for 30 years without any additional equipment, and it also ran smoothly without an external air supply.
Ask the chimney inspector; they will tell you what is necessary.
I will install a flue gas monitor in the room anyway for a few extra dollars, although technically it wouldn’t really be necessary in our case.

If the stove draws air from inside, its output must be matched to the air volume to avoid potential CO2 hazards. Our chimney sweep approved our three stoves without outside air supply without any issues.Really? Where does the air come from then? I’ve never seen that in a modern house. Our chimney sweep rejected that immediately, which is good, especially with controlled residential ventilation, but even without that, I would find it unusual. Our pressure monitor failed after 3 years, repair costs were 1000€... The combustion control would have been an additional module.H

Never seen that in a modern house. That may be. You are warmly invited to come and have a look.

You can also check at our place. The air comes from the room, which has enough. 44 sqm (473 sq ft) open-plan living area plus 16 sqm (172 sq ft) hallway (without a door between), but no mechanical ventilation system and only a recirculating extraction hood. With this setup, the room-sealed wood stove without external air supply was approved by the chimney sweep; even the open-plan living area alone would have been sufficient. The stove also burns very well; when starting the fire, it is sensible to open a window for a few minutes.
