Old heating system
The old heating system was a 30 year old gas powered system, that was at the end of its lifetime. Tldr. mostly broken, to high gas consumption and a lot of rust.

Cleanup
First I disassembled the old heating system and moved that heavy stuff with the help of my family and friends out of the basement. After that I cleaned the walls, where the old heating system was and cleaned the chimney. Lastly I removed a bricked-up door with plasterboard, that had a moldly surprise.
