There's a real answer here. I'm not including the boiler house in the visitor center model. In the original picture, shown here for reference,
you can't really understand what's going on with the building next door. It has lots of stacks, but is very skimpy on the details. Since this was the only view of the distillery I had, it wasn't much to go on. Therefore, I created my own rendition of the "building next door" and wanted it for my layout. Since it's a fiction, it wasn't worthy of being replicated for the visitor's center. If (and when) Andre and I decide to offer Bernheim as a kit, I may or may not include my version of the boiler house as part of the complex.
