OK Alan, you clarified my understanding.

It is not obvious what > you calculated for this value and that is what I question. Sorry if > this is not clear. You missed my point entirely. I calculated the required water flow to AVOID steam. With 22kW total power, and setting the output temperature to a safe 50C (roughly 25C greater than the inlet) I calculated the required flow (12 litres/minute), and then checked to see if that was reasonable for a 2cm tube. It seems to me that it is.
