Patterson-Kelley continues to transform the commercial boiler industry by offering the highest quality, most efficient, condensing products available. Our newest stainless-steel condensing boiler is designed for maximized comfort during those long cold winter days, without sacrificing savings.
Built to transform the commercial boiler market, this top of the line, highly efficient condensing boiler is designed to provide long-term savings in energy cost. The P-K STORM™ is AHRI Certified at 97.1% thermal efficiency with 10:1 mechanical turndown capabilities.
Patterson-Kelley has achieved higher turndown with a unique mechanical process that allows the gas valves to control boiler performance without increasing excess air. This results in building flexibility and efficiency.
This method delivers a 10:1 turndown rate while preserving a high dewpoint, which helps maintain high condensation levels. This higher turndown capability will provide designers the ability to match input to building loads without sacrificing efficiency and reliability. No more nuisance flame failures that have traditionally plagued high turndown boilers.
The heat exchanger is designed to provide simplified and quick annual maintenance. The heat exchanger door swivels open providing full access to the tubes and burner inside the unit. This makes any maintenance, including cleaning, a quick and cost-effective process.
Factory assembled and tested for outdoor installations with efficiencies up to 97% and a 10:1 mechanical turndown rate, outdoor models come assembled from the factory without requiring time in the field to make conversions. For buildings with limited indoor space, this option on the P-K STORM™ is ready for any predicted forecast.
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.
