Peerless® Combi 160™

Products » Residential Boilers » Peerless® Combi 160™

The Peerless® Combi (PC) 160™ gas-fired boiler is a 91.1% efficient condensing boiler that uses premixed burner technology for optimal combustion. The boiler offers hydronic heat and domestic hot water in one complete unit by using an integrated coil-type hot water tank! Stainless steel tubes and an ASME rated heat exchanger are also features of the boiler. The patented premix air/gas modulation system, domestic hot water heat exchanger, and electronic controls make the PC160™ condensing boiler a top-notch choice for performance and dependability, safety, low emissions, and “green” operation.

Panel mounted controls, an installed and wired circulator and expansion tank are all built into an attractive, sound attenuated enclosure. All utility connections for gas, water and condensate are conveniently located at the bottom of the unit. The wall mounted boiler design allows for ease of installation, maintenance and service.


Venting is provided by a standard concentric vent kit* that allows the boiler to be vented either “through-the-wall” or vertically for maximum installation flexibility. The concentric vent kit utilizes outside air for combustion thereby reducing air infiltration, thus lowering fuel bills. Optional components to increase venting lengths are also available.

*Please note: PC160™ venting components are not interchangeable with Peerless® PUREFIRE® and Pinnacle® Oil venting components.

Domestic Hot Water

Enjoy ample low-cost domestic hot water without the expense of a separate water heater. The built-in tankless heater is capable of producing up to 4 gallons of domestic hot water per minute. The tankless heater can be removed from the boiler unit for hassle-free cleaning.
