There is a concern about the steam and where it goes in Blatzhaus Electric Brauerei!
generally, you would install a vent hood and exhaust fan - I had one installed in the house I was building where this system was originally intended to go, but given I am doing this in my garage, for now, I just open the big door and my back door and that seems to provide enough ventilation (i.e. no condensation buildup anywhere.
but one day I hope to insulate and AC my garage, in which case I will install a vent hood.
