Features

    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. The sections also contain heat pin studs which improve heat transfer and efficiency by diverting hot gases.
  • Efficiency-Boosting Insulation
  • 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.
  • Captured Seals
  • Elastomer rings seal the sections' ports better than traditional metal push nipples. The elastomer expands and contracts with the section, maintaining a watertight seal in all conditions.
  • Easy Maintenance
  • 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-5-S is 9 and forms an internal header within the unit. This improves water circulation
  • Jumbo Steaming Area
  • Weil-McLain believes you should never have to wait for dry steam. The LGB-5-S features an extra-large steaming area for express steam generation and ideal comfort.
  • Product Note
    The Weil-McLain LGB-5-S 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.

Medium Learn More
Medium
Medium refers to the substance that carries heat through the heating system. Systems are either designed to use either Hot Water or Steam as a medium, and components are usually specific to one or the other.
Steam
Heat Exchanger Material
Cast Iron
Fuel Type Learn More
Fuel Type
To create heat, some form of fuel is required. Fuel Type specifies what the product uses as an input to create heat.
Natural Gas
Combustion Type Learn More
Combustion Type
Condensing appliances use leftover thermal energy from combustion gases to heat water in a secondary heat exchanger, resulting in higher efficiency and lower exhaust temperature.
Conventional
Vent Type Learn More
Vent Type
Products that use combustion (burning) of fuel to create heat also create potentially dangerous gasses that need to be exhausted (AKA "Vented"). Depending on the product, venting can be done via a chimney, through a side wall, or use a second vent to provide fresh air to the appliance.
Chimney Vent
DHW Production Learn More
DHW Production
DHW (Domestic Hot Water) is potable water for uses other than space heat. Some boilers are able to provide DHW "out of the box", while others can do so with the purchase of optional accessories.

Modulating/Staging Learn More
Modulating/Staging
Stages are unique speeds or levels that equipment can operate at. More stages allow for better fine-tuned control of output, which improves comfort and efficiency. Modulating equipment can operate across a range of levels, giving the highest level of fine-tuned control. Learn More

Performance
AFUE Learn More
AFUE
AFUE (Annual Fuel Utilization Efficiency) measures the efficiency of combustion equipment over the entire heating season, and is calculated by dividing the amount of energy that is actually heating your home by the total energy contained in the fuel used by the boiler/furnace. Learn More
81 %
Maximum Input Capacity Learn More
Maximum Input Capacity
The Maximum Input Capacity describes how quickly the appliance will use fuel when delivering it's maximum capacity. The units may change depending on the fuel being used.
520000 BTU
DOE Heating Capacity Learn More
DOE Heating Capacity
Also referred to as Gross Output, this is the output of a boiler after accounting for combustion efficiency. We recommend sizing hot water boilers based on the DOE Heating Capacity.
421000 BTU
Net I=B=R Capacity Learn More
Net I=B=R Capacity
I=B=R, also referred to as Net Output or AHRI Capacity, is the rated heat output of a boiler after accounting for combustion efficiency, piping loss, and an extra pickup factor. We recommend sizing steam boilers based on the I=B=R rating.
316000 BTU

Combustion Efficiency
Ultra Low NOx Emissions Learn More
Ultra Low NOx Emissions
NOx is a byproduct of the combustion process, and it's output is regulated in some jurisdictions. Many regulators mirror SCAQMD rules, which regulate air quality for some parts of Southern California. Ultra Low NOx appliances emit less than 10-14 ng/J (nanogram per Joule) of NOx. Learn More
