With the Badcha Upgrade, you can expand the Badcha Woodpecker V2 into a heat management system.

The upgrade to the Badcha Specht V2 is very simple.
Similar to a Kaloud Lotus, you can adjust the air draft at the top using the handle, which for the most part does not get hot.

The lower lid has a material thickness of 6mm and the upper lid 3mm.

Of course, the upgrade can also be used with other commercially available fireplace attachments with a strainer.

With this attachment you have a coal saving of up to 33%, as commercially available coal can still be used up to a residue of 20%.
Adding coal only requires 1-2 pieces of coal (25mm x 25mm x 25m).
