Technically you are correct. buttt.. For a dumpster diver and water removing tank I was thinking of the vacuum energy coming from cheap elbow grease. As in using a hand/foot pump in reverse arrangement. Dont you only have to pull the vacuum to the desired level and then close the valve on the pump so it holds that level of vacuum durring heating? this would save in dollar/energy cause it would take less heat.
For an onboard dewatering tank I would use engine vacuum. This is what Im thinkging about in my Unimog Camper's on board filtration system (still in the design stages).
