A History of Cutting Edge Innovation

Started as Benjamin F. Kelley & Company in 1880, Patterson-Kelley has evolved over the years, adapting to lead the marketplace. The company’s first product, feed-water heaters, introduced pioneering technology with tube bundles.

In 1917, Frank L. Patterson merged with Kelley to form Patterson-Kelley Company Incorporated. After World War II, the company’s focus shifted from storage water heaters, to more the complicated, custom-engineered heat exchangers and other heat transfer products. In 1987, the company entered the gas-fired commercial boiler industry.

This outstanding level of innovation continues, even today, in all of our PK products! Don’t believe us? Check out our proprietary NURO Touch Screen Control System that, when used alongside the NURO Connect App, allows users to monitor and adjust their system settings from anywhere in the world at any time of day or night!
