Hey. I recently installed a cassette where I used to have a fireplace. I did this solely to start burning more and avoid paying those expensive district heating bills.
Anyway, I've placed the cassette and have it inspected. But now I want to get heat into another room that is behind a 1-meter concrete wall from the cassette. I've received tips on how to spread the heat. They said you can drill a hole through the wall to the other room and place a fan there. This spreads the heat from the room you are burning in so that the heat spreads to the other room as well.
Question:
What kind of fan is it? Feel free to share tips and recommendations.

Is there anything else I need to consider? Let me know.
Best regards
