ᐅ Ventilation grille for wood-burning stove

Hello everyone,

Does anyone know of an elegant solution to avoid the unsightly fresh air grilles for a plastered wood-burning stove?
Unfortunately, external air supply is no longer possible since the screed is already installed.
Drilling into the basement is also not an option.

I am grateful for any ideas.

Best regards

We installed "invisible vents" above a masonry fireplace to help distribute the warmed air more effectively throughout the room. For this, we used dark natural stone veneers and made the joints slightly wider. In the areas where the air outlets were located, we omitted the mortar, leaving the joints hollow so that air can escape at multiple points.

Because the background, the veneers, and the joints are all dark, the slots are visually hard to notice.

For the supply air, this approach would only work if a larger supply air area is available (possibly on three sides) and if the supply air volume can also be adjusted at the stove.
