The Weil-McLain approach to high-efficiency heat exchanger design

April 14, 2020

Across the boiler industry, a various approaches and claims have been developed to differentiate heat exchanger designs around the features of efficiency, reliability and service life longevity.  These include approaches to reduce thermal expansion, expansion gaps, floating tube designs and alternate grades of stainless steel and hybrid makes of material.

Here are the fundamentals built into Weil-McLain heat exchanger designs.

Design geometry

Weil-McLain heat exchangers employ casting and tube geometry designs that are time-tested across thousands of working applications in North America and that deliver industry-leading efficiency.  We combine heat exchanger solutions with boiler package experience earned over 140 years of listening and serving our customers.   

High-flow water and weldment design

Weil-McLain heat exchangers employ high mass, high flow design approaches, known for reliability, service life longevity and boiler system protection.  Large mouth firetube designs with fewer robotic precision weldments and lower water flow velocities differentiate our boilers from the rest of the industry. 

Weil-McLain’s design philosophy and, more importantly, our standards are quite simple: To offer the best overall value to our customers, a commitment that we have kept since 1881.
