And so..............to heat the water manually without the engine running, the van heater needs to be full on which in turn circulates the hot fluid pipe through the calorifier that heats the water. But it takes a long time from what moojuice says. How longs a long time? An hour?

From experience the eberspacher is better at heating up the heater matrix than it is the calorifier. When I first got the van a year ago, we played around with filling the calorifier up fully (12 pints of cold water) and then ran the eberspacher for an hour. The water became luke warm, the cab could heat up nicely.
From what I can tell of the way its all plumbed in i dont think it will make much difference to the calorifier if the hot cold knob in the van is on hot or cold - that only controls hot or cold air blowing into the cab.
Then we refilled the calorifier with cold water again and I drove back home via a few places. After about half an hour of driving about the water was VERY hot. I wouldnt bother running the eberspacher (D5W is 5kw) to try and heat up an engine block, heater matrix AND calorifier and expect the calorifier to produce very hotwater in an hour. Probably quicker to use a gas hob and big kettle, or leave the engine ticking over for half an hr.

But getting it to heat just the water is a good idea, although sadly its the tank capacity that really kills it for me. Something like 6 litres isn't enough for a day for a couple of people in a campervan. A different water heating route for me at some point will indeed be happening.
Its very helpful to know what kind of beast I'm dealing with until then though.
