$/GPM is the price divided by the hot water flow the heater delivers at a 45 °F temperature rise, worked out from its gas input and UEF. "Box GPM" is the maker's own maximum, often quoted at a much smaller rise, so it is shown but not ranked on. Your rise depends on your incoming water: the sizing calculator works it out from your ZIP.
Is it big enough for my house?
At full fire this heater puts about 144k BTU/h into the water. Enter your household and ZIP code in the sizing calculator: it works out how cold your water arrives in winter, the peak flow your showers and taps need, and whether this heater keeps up. Open the sizing calculator.
Install: needs a gas line sized for its full BTU input and a 120 V outlet for the controls.
