Indeed, the simple fact that it doesn't make sense is troubling.
And, to be counted as part of that "not making sense" is what is needed to do the testing and get the results that their own PR stated was the mandate given to Intertek. Very simple overall performance data collected in multiple manually configured settings, all of which needed nothing more than measurement of water rate of flow, water inlet temperature, water outlet temperature, electical power consumption, and time. Equipment for those measurements would be readily available. So, that brings focus on the "why" which caused the abrupt termination of testing.
