What actually separates them

The PHW-750 is rated 750,000 BTU/hr input and 637,500 BTU/hr output with not printed turndown; the PHW-1000 is rated 1,000,000 BTU/hr input and 840,000 BTU/hr output with not printed turndown. Both models carry the same published efficiency column in the official data sheet.

The PHW-1000 adds 250,000 BTU/hr of input over the PHW-750, steps the gas connection from 1 in to 1-1/4 in and is also offered as the PHW-950 (950,000 BTU/hr input, 800,000 BTU/hr output). Flow tables for both sizes are printed in the family data sheet. Dry weight steps from 1,800 lb to 1,800 lb, so rigging and floor loading should be checked against the larger unit.

Both sizes are documented in the same official Fulton data sheet, so the choice is a heat-loss and plant-layout decision: size to the design-day load, then verify connection sizes, venting and weight against the sheet for the exact model.
