Over the last 130 years, Weil-McLain has built a reputation of designing some of the most reliable boilers in the marketplace. Their dedication to producing lasting heating solutions is seen in every boiler they make. The LGB brings Weil-McLain reliability to the largest of applications. The LGB is available for natural gas or liquid propane installations in either steam or hot water. There are 20 sizes available, and that is just the beginning of customization. Weil-McLain knows that no two massive applications are the same, so they have developed a variety of control packages for the LGB. To keep installation and piping simple, Weil-McLain has ensured that even the largest LGB only requires two risers. When it comes to large applications, the LGB brings versatility, efficiency, and reliability together in a package that fits your application.
Durable, Efficient Construction
Corrosion-resistant, cast-iron boiler sections mean that your LGB will withstand the rigors of even the most trying applications. Cast-iron was chosen for its durability and longevity. The sections also contain heat pin studs which improve heat transfer and efficiency by diverting hot gases.
Heat retention is critical to energy efficiency. Heat leakage represents energy use without any comfort gains. An extended, insulated steel jacket prevents heat from escaping the LGB and improves the efficiency.
Elastomer rings seal the sections' ports better than traditional metal push nipples. The elastomer expands and contractors with the section, maintaining a watertight seal in all conditions. Sealing rope between each section serves the same purpose and achieves the same absolute tightness.
Keeping the LGB clean and running efficiently is a breeze. The rear jacket and steel cleanout plates are easily removable, providing quick access to the flue passages.
Jumbo Top Port
The top port opening of the LGB-21-W is 9" and forms an internal header within the unit. This improves water circulation, which leads to even comfort and reduced wear-and-tear on your LGB.
The Weil-McLain LGB-21-W has several standard options that must be selected before your order can be placed. Please contact an eComfort.com product advisor to discuss the fuel type, assembly type, and control system that best suit your application. Any additional, optional upgrades must be added at this time as well.
