Boiler Supply Company

What Boiler Supply Company does

Boiler Supply Company (operating as Boiler Supply Co. / boisco.com) is a privately held, family-owned industrial boiler systems distributor and service provider founded in 1942 in Nashville, Tennessee and now headquartered at 2400 Kline Ave, Nashville. The company has been an authorized representative for Cleaver-Brooks, the largest U.S. manufacturer of packaged boilers, since 1962, and it ranks consistently in the Top Ten of Cleaver-Brooks' national agent network for both equipment and Perma-Pipe products. Across five Southeast offices (Nashville, Knoxville, Chattanooga, Fairburn/Atlanta, and Augusta), the company sells, installs, services, rents, and trains customers on commercial and industrial boiler systems used in healthcare, manufacturing, education, government, beverage/distilling, hospitality, and large commercial facilities.

The core product portfolio centers on Cleaver-Brooks equipment — including the ClearFire-CE condensing hydronic boiler (up to 99% efficiency via patented TurboFer heat exchangers), CBEX firetube boilers with integrated boiler/burner/controls (EX technology), FLX flexible watertube boilers, electric boilers, packaged skid systems, ProFire/NATCOM burners, deaerators, and the Hawk control system with color touchscreen, O2 trim, parallel positioning, and Modbus BMS integration. Adjacent lines include Camus condensing boilers and water heaters, Wilo and Thrush pumps, Van-Packer venting/grease duct, and water treatment systems (softeners, dealkalizers, condensate return). The service stack — 24/7 emergency dispatch, ASME/National Board R-Stamp pressure vessel repair, installation/commissioning, mobile boiler rentals, mobile demo trailer, and Boiler Plant Optimization (BPO) assessments using 243 data points — is delivered by 40 factory-trained technicians with an in-house engineering group.

Revenue is generated through a mix of one-time capital equipment sales (new boilers, skids, burners), transactional parts and supply sales (genuine OEM Cleaver-Brooks parts), recurring professional services (service contracts, repair, installation/commissioning), usage-based mobile boiler rentals, and professional training services. Pricing is custom quote-based per project rather than published list. The go-to-market is exclusively direct enterprise field sales plus authorized Cleaver-Brooks channel representation, targeting facilities with complex boiler room requirements across Tennessee, Georgia, Kentucky, and Virginia. The company has completed four disclosed acquisitions (Applied Industrial Company of Georgia, 1995; Allen Welding Company, 2001; Davis Boiler Repair Company, 2003; Advanced Boiler Company, 2022) and holds Tennessee State Board License Certificate #1 for pressure piping, the first issued in the state on July 1, 1961.
