The P-K SONIC® stainless steel, condensing boiler surpasses all expectations in efficiency, size, and material design.
Patterson-Kelley’s stainless steel boiler breaks through the limitations of all other stainless designs with sizes utilizing our revolutionary DUET™ technology. This is the industry’s first heat exchanger comprised of two unique chambers built to optimize the turndown process. Our unique heat exchanger designs allow the P-K SONIC® to operate to 97% AHRI efficiency with up to 7:1 turndown and ultra-low NOx emissions.
Equipped with DUET technology, the P-K SONIC® is the premier stainless steel design for condensing applications in the industry. The innovative zones are engineered separately using different composite stainless materials that, when used together, deliver better heat transfer and higher reliability throughout the condensing process.
In most cases, there’s no rigging required to put your P-K SONIC® condensing boiler in any room of your building, whether it’s the basement or the penthouse. All P-K SONIC® condensing boilers fit through a standard 36-inch doorway and standard elevator.
The SONIC‘s clean, compact design allows internal components to be accessed with ease, saving time and money associated with repair and maintenance. Front maintenance accessibility encourages annual servicing to increase boiler life and performance.
All of our boilers are equipped with the most intuitive interface in the industry, the NURO® Touch-Screen Control. Designed to maximize efficiency, the NURO® Control System monitors and modulates the combustion and ignition of the boiler to maintain the desired outlet temperature.
