Comparison
Verdict in brief
The PHR160-55 steps up the Pioneer's firing range to 40,000-160,000 BTU/hr and its venting to 3" (200 ft) or 4" (200 ft), while restoring the line's 95% printed thermal efficiency. The physical package is unchanged: 55 gallons, 260 lb, 23 x 56 x 34 in and 1-1/4" NPT connections.

| Specification | HTP PHR130-55 | HTP PHR160-55 |
|---|---|---|
| Input rate, minimum | 35 MBH | 40 MBH |
| Input rate, maximum | 130 MBH | 160 MBH |
| Thermal efficiency (as printed) | 94 % | 95 % |
| Shipping weight | 260 lb | 260 lb |
| Tank water content | 55 gal | 55 gal |
| Dimensions (W x H x D) | 23" x 56" x 34" | 23" x 56" x 34" |
| CH supply/return connection | 1-1/4" NPT (female) | 1-1/4" NPT (female) |
| Venting | 2" (85 ft) or 3" (125 ft), combined equivalent feet | 3" (200 ft) or 4" (200 ft), combined equivalent feet |
Input runs 35,000-130,000 BTU/hr at 94% on the PHR130-55 and 40,000-160,000 at 95% on the PHR160-55 per the retired page table; the minimum fire rises 5,000 BTU/hr.
LP-325 Table 4 changes the vent allowance at this step: the PHR130-55 uses 2" (85 ft) or 3" (125 ft) while the PHR160-55 uses 3" (200 ft) or 4" (200 ft), which can matter for long vent routes.
Weight, tank volume, dimensions, connections and the five to one turndown are identical, so the extra 30 MBH of ceiling and the venting change are the deciding factors.
The HTP PHR130-55 is the 130 MBH class model of the retired Pioneer 55-gallon high-mass condensing heater line: 35,000 to 130,000 BTU/hr input, 94% printed thermal efficiency and a 260 lb package, recorded from the official retired Pioneer table and LP-325 Table 4.
The HTP PHR160-55 is the 160 MBH class model of the retired Pioneer 55-gallon high-mass condensing heater line: 40,000 to 160,000 BTU/hr input, 95% printed thermal efficiency and a 260 lb package, recorded from the official retired Pioneer table and LP-325 Table 4.
Yes — LP-325 Table 4 prints 3" (200 ft) or 4" (200 ft) for the PHR160-55 against 2" (85 ft) or 3" (125 ft) on the PHR130-55.
The PHR160-55 prints 95% against 94% for the PHR130-55.
Yes — both are 55-gallon, 260 lb units with identical dimensions and connections.
A consultation includes a heat-loss review so the size is right the first time.
