Precision Boilers has a long history of boiler design and construction success.
Precision Boilers entered the hydronic heating and plumbing industry in 1946, when the Precision Sump Pump was engineered, developed and put into production. A year later, the first Precision electric boiler was designed and fabricated. The company continued to grow, and its reputation and capabilities kept expanding.
In January of 1983, Precision Boilers was sold to Machinery Manufacturing of East Tennessee and relocated to Morristown, TN. The new leadership of the company kept building on previous successes, expanding to a multi-line manufacturing operation still serving the heating and plumbing industry. The line at this point included electric hot water and steam boilers, plus electric hot water storage heaters.
In the 1980s, gas fired products were developed, and the introduction of atmospheric-gas-fired copper finned tube and power-gas-fired vertical Fire Tube boilers and water heaters followed. Growth continued with the expansion of the ASME pressure vessel line to include flash tanks, air receivers, air separators, bypass feeders, blowdown tanks, and condensate return/boiler feedwater systems. In addition, indirect fired packaged hot water and steam generators, heat transfer packages, and accessory products were introduced.
In 1988, Precision Boilers entered the heat side thermal storage business by purchasing the technical and engineering data of Megatherm, Inc., a Rhode Island company who had built thermal storage products for over 20 years. Now manufactured under the trade name Thermogenetic™, the systems are custom designed and utilize pressurized high temperature water storage from 240 to 18,000 gallons to provide domestic hot water, hydronic heating water, or process hot water. They are fired with electricity, steam, gas, oil, or a combination thereof.
In 1990, the Precision Compac™ Boiler was introduced. The Compac has the smallest footprint in the industry, and packs up to 264 kW in a cabinet 24" wide and 30" deep. It can go easily through a 28" doorway. A slightly larger version of the boiler offers 480 kW.
In 1991, an increase in personnel in engineering allowed Precision Boilers to expand its scope of custom products and services. Models such as superheaters, circulation heaters, electric high pressure steam boilers (up to 3,000 PSI), electric and steam dual-fired heaters, high voltage electrode boilers and condensate return/boiler feedwater systems became available. Other products such as vertical Fire Tube power gas fired boilers/water heaters, indirect fired storage water heaters, and semi-instantaneous water heaters have gained significant market share.
In 1994, Precision Boilers invested heavily in a new factory, doubling its production areas. The new plant was expanded again in 1997, and plans for further expansion are on the board.
Precision Boilers is ISO 9001:2000 certified, and holds the coveted Chinese Safety and Quality License, which opens up even more opportunities through exporting.
Precision Boilers’ quality policies & principals are designed to ensure all products and services consistently meet or exceed customer requirements. Always achieving high customer satisfaction is our goal.
