Peerless Purefire PF-50-210
Model Number: PF-50 through PF-399 (family)
Residential PureFire is a gas-fired stainless-steel condensing hot-water boiler.
Technical Specifications
Source: manufacturer spec sheet
Prices depend on sizing, venting and piping in your home, so we quote every installation.
Sizing: the right size comes from a room-by-room heat-loss calculation, not the size of the old boiler or a rule of thumb. Oversized boilers short-cycle and waste fuel; steam systems are sized to the connected radiation instead. See how we approach boiler installation.

Expert Review: Peerless Purefire PF-50-210
Residential PureFire is a gas-fired stainless-steel condensing hot-water boiler.
Peerless residential PureFire brochure spans PF-50 through PF-399; this page label covers an older subset 95.0–95.2% AFUE depending on model; five-year parts coverage requires registration Listed input range: 16–210 MBH input. Rated efficiency on file: 95% (confirm the rating method for the exact size on the spec sheet). Venting on file: PVC/CPVC/PP/SS. Can supply domestic hot water through an indirect tank.
It is best suited to homes replacing a gas hot-water boiler with a condensing unit. Before ordering, a contractor should complete a room-by-room heat-loss calculation, check the distribution system's water temperatures and confirm venting and clearances against the installation manual.
Pros: Condensing design captures heat from flue gases when return water is cool enough. Modulating burners can match output more closely to mild-weather loads. Can be paired with an indirect water heater for high-volume hot water. Multiple sizes (16–210 MBH input) allow sizing to a calculated heat loss. Considerations: Confirm the exact size, vent and condensate requirements; the family name is not a sizing calculation. Condensing efficiency depends on low return-water temperatures; high-temperature radiation may limit real-world savings. Requires a condensate drain and, in many homes, neutralization, plus manufacturer-approved vent materials. Some details on this page still await manufacturer verification; check the spec sheet before relying on them.

Sizing & Installation Notes
Condensing boilers like the Purefire PF-50-210 reach their rated efficiency only when return water runs cool enough to condense flue gases. We check your radiation and design water temperatures so the unit actually condenses in your home, not just on the spec sheet.
