Joosep staning next to our steaming test setup. We will use our garages powerful ventilation to condensate the steam, keeping it away from the inside room. I bet the moisture content in the room would rise after a day of steaming. Like a sauna. Notice the strongback under the piping. The tube will deform under heat. The strongback will keep it firm. We will wrap old rags around the whole thing to keep it warm and condensation as low as possible, to get the hottest steam.
