Weil-McLain, a division of The Marley-Wylain Company, is a leading North American designer and manufacturer of hydronic comfort heating systems for residential, commercial and institutional buildings since 1881. Building on a reputation of quality and innovation, the Weil-McLain brand is committed to creating Simplified Solutions for our Complex Worldâ„¢. The reliability and energy efficiency of Weil-McLain products has helped them make them industry leaders. Weil-McLain products are engineered with aesthetics, functionality, safety, and structural tolerance in mind.
Over the last 130 years, Weil-McLain has built a reputation for 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 CGi represents excellent durability and efficiency in a space-conscious package. Supporting both natural and induced draft venting, this is the perfect boiler for any application, regardless of chimney access. The CGi is designed in a way that does not require a vertical draft hood, keeping the low profile that makes this boiler so attractive. Whether you are replacing an older boiler or beginning new construction, the CGi is an efficient, compact heating solution.
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 CGi and improves efficiency.
Durable Construction
- Reliability is one of the greatest ways a boiler can provide value. Weil-McLain wanted to be sure that you’ll enjoy the comfort the CGi provides for years to come. With a steel base and burners and cast-iron boiler sections, they have done just that.
