Peerless Purefire Boilers

If your home has hot water radiators in each room for heat, you have a boiler to heat the water. Like a furnace, the energy efficiency of a boiler is given as the Annual Fuel Utilization Efficiency (AFUE). Boilers manufactured since 1992 must have an AFUE of at least 80%. We offer a complete line of gas and oil boilers starting at 80% AFUE and up.

The Peerless® PUREFIRE® gas-fired condensing boiler is a high-efficiency boiler for residential and commercial applications and is available for either natural or LP gas. The direct vent, sealed combustion boiler has an ultra-high efficiency - up to 93.3% - and is ENERGY STAR® approved*! The PUREFIRE®, available in six sizes has ASME and ETL certifications for both the U.S. and Canada and is the most thoroughly tested high efficiency boiler on the market! A unique condensate system with built-in neutralizer component and float switch protection is a top feature of the boiler.

Other great features include a high grade stainless steel burner and heat exchanger, 120 volt convenience outlet and LoNOx operation for the good of the environment. The PUREFIRE®’s fully modulating burner assures dependable operation and maximum boiler efficiency. Zero clearance to combustibles, easy access to controls and leveling legs are other standard features that allow for ease of installation and maintenance. Boilers are easily converted from LP to natural gas and from natural gas to LP without any additional parts. The PUREFIRE® is equipped with a full one-year parts and labor warranty (see “Warranty” section on this site for complete details).

*Residential models; 95.5% combustion efficiency for PF-399® (see PF-399® product page for more information).

STATE-OF-THE-ART CONTROL BOARD

All Peerless® PUREFIRE® gas boilers are equipped with a state-of-the-art control board that offers modern technology such as an outdoor reset control with an additional outdoor temperature sensor and is cascade capable for operation of up to 16 units as a single module. The control board also has built-in technology for domestic hot water priority and an energy saving heat recovery function that improves hot water performance and reduces off cycle losses. Standby temperature of domestic hot water is controlled by economic low fire operation. Additionally, the control board’s LCD status display module uses plain English for easy-to-read status and troubleshooting text while a switch to "system test mode" enables contractors to manually control the firing rate.
