18. Heating system with 4.5x5 bricks. For myself.
Don't judge too harshly. You can give it a thumbs up. Fireclay is glued with Master+ mastic or Terracotta, or something similar. Red brick is laid on clay. The first row of fireclay bricks is laid on top of the red brick on the clay. If you're installing the stove on a wooden base, don't forget to lay out a zero row similar to the first, but mirrored. I removed the extra shelves from the stove to avoid creating a dust collector. The cladding is up to you.
