The Highest Quality Industrial Boilers 

Johnston Boiler Company manufactures the worlds largest Scotch Marine firetube boiler. We pioneered the first water backed boiler over 100 years ago and the first packaged boiler, over 65 years ago. Our commercial and industrial boilers are built to last and are the only industrial boilers in the industry to carry a 15-year warranty. In addition to the quality and dependability of our products, the conservative design of our boilers provide excellent fuel to steam efficiency, resulting in the absolute best life cycle costs in the industry.

Ancillary Equipment

Johnston also offers a full line of deaerators, surge tanks and blow down heat recovery systems. These feedwater systems are also designed and built to a quality standard which allows us to offer a 10 year warranty, the only one in the industry.

Environmental Awareness 

We are well aware of the changing environmental requirements. While our standard Johnston burners can attain less than 30 ppm NOx, we understand that some regions of the United States are requiring NOx emissions as low as 9 PPM. We are constantly striving to implement the best available technologies in our products. In many cases, we are able to meet or exceed the emissions requirements set by the EPA, and we will continue to explore areas of improvement.

At Johnston Boiler, we have proven technology that will increase the reliability and efficiency in your facility, making it the Big Green Machine that saves you money.
