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.

There are basically two options.
Fresh air can be supplied through the chimney (LAS) or through a pipe in the floor. However, you always need air from outside!
The required area depends on your stove and can be found in the manufacturer’s specifications.
The stove comes with the shut-off mechanism. However, there are also electronic fire control systems that would be installed before this. They are very expensive and tend to break down quickly.

If the stove draws air from indoors, its output must be matched to the air volume to prevent potential CO2 hazards. Our chimney technician approved all three of our stoves without any external air supply.

I hope not! Combustion control increases efficiency, optimizes emissions, reduces the risk of chimney fires, and is quite convenient (just light it and you’re done). High-temperature sensors and damper controls aren’t rocket science either. We’ll see when the first defect happens…

The burn rate control increases efficiency

From this, I gather:
Do you have such an electronic control system?

We have a masonry heater with Ortner technology and a burn-rate control, and two Hase wood stoves without one.

..... thinking ....

I believe we currently have enough "new" electronics in/on the house ... (photovoltaic system and electric car)
