I realize this is a crude estimate. I believe that I.H. has better numbers based on measuring the flow rate by other means. I have not seen these numbers. I hope they are published eventually. My point is that you do not need a gigantic error in the flow meter for there to be no excess heat. The meter itself does not have to be wrong by a factor of fifty to produce an apparent COP of 50 where the actual COP is ~1. A combination of errors from the flowmeter, temperature and pressure readings is more likely. I think a flow meter error somewhere between 3 and 6 is not out of the question, especially given the Defkalion results. - Jed
