Company history
Founded in 1993, Power Plus International began in a humble home garage and spare bedroom. From those modest beginnings, the founders were driven by a clear mission: to deliver products and service that stood out in an industry where such dedication was rare.
By 1995, the company took its first steps toward growth—bringing on its first inside salesperson and an account manager. Though still small, the team worked tirelessly (often 17-hour days) and laid the foundation for what would become a full-service industrial supplier.
In 2002, as reputation and volume increased, Power Plus International made a significant move into a 5,000 sq ft facility located in an industrial park. That same year, the company launched its first website to meet the rising demand from customers seeking better access and information.
By 2005, the company had grown into a recognized name in the boiler and industrial markets, operating multiple specialty sites including BoilerSupplies.com, GageGlass.net, BoilerGasket.com, TubeBundle.com, and Heat-ExchangerUSA.com.
Today (2025), Power Plus International continues to serve the boiler and industrial sectors from its 14,000 sq ft headquarters in McDonough, Georgia, supported by a dedicated team and a loyal customer base.
Transition to boiler usa
As part of our evolution and ongoing commitment to innovation in the boiler industry, Power Plus International is now rebranding and transitioning to the name Boiler USA. This change reflects our sharpened focus, expanded capabilities, and reinvigorated vision to lead in boiler solutions across the United States. While our name is changing, our dedication to quality, service, and partnership remains stronger than ever.
