Why does my car RPM go up when AC is on?

Does a car use more gas when the heater is on?

How does the air heater in a car work?
Air-cooled cars. If necessary, the air may be warmed further by an electrically ignited petrol-burning heat exchanger. The heat exchanger also allows the heater to work with the engine off -unlike a water-heated type. The rest of the system, the way in which the heat is distributed, is like that of any other car.

Why does the heater only work when the engine is revved?
This sounds like a typical problem these vans had which is they get air trapped in the heater core which makes it difficult for coolant to enter the heater, This is why it only works when the engine is revved. I would make sure the coolant is full then start the engine and turn the heater on full blast.
