Hydronic comfort heating provider Weil-McLain has announced the availability of its 2023 Department of Energy (DOE)-compliant commercial cast iron product portfolio with enhanced boiler efficiencies. The upgraded designs of the LGB Steam/Water Series 3 and 88 Water Series 3 boiler product lines include new features that go beyond just regulatory compliance.
DOE regulation 431.87 states that commercial boilers manufactured after January 9, 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% and combustion efficiencies up to 81%. Additionally, the 88 product family is 2023 DOE-compliant with thermal efficiencies up to 87% and combustion efficiencies up to 88%.
