Hi all, love this forum. I want to give a shout out to the person/people who created the Pumping 101 Excel tool. Fantastic work. I'm performing a cost benefit analysis and found some interesting data. At 26gpm @ 1050rpm and using curve-C, the Energy Cost tab indicates 27.2 g/whr for the TriStar VS 1.85 URHP unit, which is nearly twice the efficiency compared to the Superflo VS, and IntelliFlo 1, 2, & 3hp models.
Is the Tristar really that efficient?
Even so, it doesn't pay back unit around month 30 for my case using current internet pricing, but still, pretty great if it's true.
