Verdict in brief
The Pulse PHW-2000 adds 600,000 BTU/hr of input and 496,000 BTU/hr of output over the Pulse PHW-1400 on the same Pulse (PHW) platform. The PHW-2000 is the largest Pulse PHW: 2,000,000 BTU/hr input, a 6 in air intake and exhaust, 4 in flanged water connections and 75 gal water content, against the PHW-1400's 2-1/2 in water and 4 in vent.

| Rated output | 1,204,000 BTU/h | 1,700,000 BTU/h |
| Boiler horsepower (BTS-2000) | 36 | 50 |
| Water connections | 2-1/2" NPT | 4" flanged |
| Dry weight | 2,230 lb | 2,900 lb |

The PHW-1400 is rated 1,400,000 BTU/hr input and 1,204,000 BTU/hr output with not printed turndown; the PHW-2000 is rated 2,000,000 BTU/hr input and 1,700,000 BTU/hr output with not printed turndown. Both models carry the same published efficiency column in the official data sheet.
The PHW-2000 is the largest Pulse PHW: 2,000,000 BTU/hr input, a 6 in air intake and exhaust, 4 in flanged water connections and 75 gal water content, against the PHW-1400's 2-1/2 in water and 4 in vent. Flow tables for both sizes are printed in the family data sheet. Dry weight steps from 2,230 lb to 2,900 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.

The Fulton Pulse PHW-2000 is a gas pulse-combustion commercial hydronic boiler rated 2,000,000 BTU/hr input and 1,700,000 BTU/hr output at 50 BHP, documented by Fulton's public PHW product data submittal and I&O manual.
The PHW-2000 at 2,000,000 BTU/hr input and 1,700,000 BTU/hr output, also offered in the PHW-2000LE low-emission version.
The official installation notes state the PHW-1400 must upsize from 4 in to 6 in vent after the first 10 feet to extend the run.
A consultation includes a heat-loss review so the size is right the first time.
