About Nationwide Boiler

Integrity. Dependability. Real Customer Service.

Established in 1967 for the main purpose of providing emergency rental boilers and auxiliary equipment to steam users, Nationwide Boiler pioneered the concept in mounting large package boilers on highway-legal trailers. Since 1967 Nationwide Boiler has supported hundreds of companies and institutions in thousands of boiler installations throughout the world.

Today, Nationwide Boiler is now involved in virtually every other aspect of the boiler industry including boiler system sales, leasing, turnkey installations, boiler parts, operations, service and repair. Our commitment to supply the most technologically advanced equipment has been demonstrated by the conversion of our entire fleet of rental boilers to meet low NOx emissions and our ongoing development of high-capacity mobile boiler rooms and portable steam plants for maximum steam capacity. The development of the Nationwide Boiler CataStak SCR system and Best Performance Standards boilers contribute to our reputation as the leader in providing solutions that substantially decrease GHG emissions and increase plant efficiency.

With headquarters in Fremont, California, and sales representatives across the globe, Nationwide Boiler continues to grow and expand. Our Central Valley Sales Office in Visalia, California opening in 2015, and Pacific Combustion Engineering / Ponder Burner Company was acquired in 2017 to form Nationwide Boiler's Controls Division. The panel fabrication facility is UL508A & 698A certified, providing the highest safety standards on our burner management and combustion control systems. In 2021, Nationwide Boiler opened a new storage and maintenance facility in Alvin, Texas to better support our customers in the Gulf Coast. 

Nationwide Boiler's seasoned and strong management teams, outstanding engineering, sales and service offices throughout the world, our long-lasting partnerships, and our positive vendor relations have helped the company grown to a position of leadership recognized throughout the industry.
