Weil-McLain has upgraded designs of the LGB Steam/Water Series 3 and 88 Water Series 3 boiler product lines. DOE regulation 431.87 states that commercial boilers manufactured after Jan. 9, 2023, including knockdown, assembled block and complete package configurations, must meet higher minimum efficiency standards. The LGB family meets those requirements with enhanced thermal efficiencies up to 84 percent and combustion efficiencies up to 81 percent. The 88 Water Series is 2023 DOE-compliant with thermal efficiencies up to 87 percent and combustion efficiencies up to 88 percent. Suited for light-commercial applications, such as multifamily, municipal, education, religious and institutional settings, the LGB is available in steam and water heating designs ranging from 350 to 2470 MBH. The 88 family, which is suited for the same applications, offers a performance range of 960 to 5845 MBH and is available in steam or water boiler configurations with gas, oil and gas-oil fuel options.
