Johnston Boiler Company pioneered the first water backed boiler
over 100 years ago, and the first packaged water backed boiler over 50 years
ago. Johnston features a complete packaged boiler that needs just the essential
utility and discharge hookups before supplying your steam or hot water needs.
The complete package is thoroughly factory fire tested at all applicable loads
and fuels prior to painting and shipment.
Depending on design and operating pressure, efficiencies reach 90% - the highest in the industry without turbulators or an economizer. Minimum use of refractory and the full water back design reduces maintenance while at the same time enhances pressure vessel longevity.
From front to back, top to bottom, every Johnston "509" series boiler comes with an unprecedented - industry leading 15 year warranty covering the tube sheets, furnace, rear combustion chamber, and flue doors -materials and labor.
