We took these pictures at a customers property in France during installation.
Concrete base for unit, lovely weather ensured it was properly set ready to drop the furnace on.
We found some big pieces of wood which the customer had not split and cut into smaller pieces to show how these size pieces are suitable for loading into the boiler without backbreaking splitting and cutting into smaller pieces. All these pieces can be loaded at the same time, see video of them going in.
The wine bottle is intended to show how big these pieces are. These pieces are not seasoned enough to be used in the boiler yet, just used as examples.
