P-K SONIC®

The P-K SONIC® stainless steel, condensing boiler surpasses all expectations in efficiency, size and material design.

Models: SC650, SC750, SC850, SC1000, SC1500, SC2000, SC3000, SC4000

Dual Fuel. Natural Gas. Liquid Propane.

Patterson-Kelley’s stainless steel boiler breaks through the limitations of all other stainless designs with our revolutionary DUETTM technology. It’s the industry’s first heat exchanger comprised of two unique chambers built to optimize the turndown process. This unique design allows the P-K SONIC® to operate at 97% efficiency with up to 7:1 turndown and ultra-low emissions.

SONIC® high efficiency boilers feature a 316L stainless steel heat engine with multiple fuel options available.

Big output in a small space

Refined engineering allows for optimal space management. 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.

NURO^® Touch-Screen Control System
