So doing the math for 2 gpm(7.57 liters), you need 7.57KW to go from 60 to 75, another 7.57 to get to 90 and another 7.57 to get to 105 totaling 22.71KW needed for 2gpm. Does that sound correct? Now reduce that by some factor(no idea yet) because WDRP has the ultimate heat exchanger and uses microwaves.
