The installation of an innovative and highly efficient boiler from Weil-McLain helped make the basement remodel a success and the family’s home comfortably warm throughout.

For years, environmental considerations and sustainability have influenced innovation in manufacturing, and in 2021, those factors became the driving force behind new product development.
