Oh, he tells me that all the Rheem 100 gallon tanks are atmospheric vented, and none are power vented. So if we want a 100 gallon tank either direct vented or power vented, we are out of luck. And the power vent 75 gallons have FHR’s of 120 and are borderline for the estimates of our needs. He is going to come measure the outputs in the showers. Well, what do people with big families and with big homes, those 5 BR 5 baths, do? Banks of multiple tanks in parallel?
