That seems tricky to me because the test will run for many hours and it is difficult to establish how much heat is lost from the swimming pool. You have to do a calibration with the giant heater. You could do both methods. You should. To do flow calorimetry, I suppose you would have to trust the manufacturer's faceplate rating for the large pump. That must be an approximate number. I have seen large gasoline-powered pumps used to drain houses after floods. They are impressive. I doubt that the rating is precise. - Jed
