In 1975 Industrie Merloni split into several companies, including Merloni TermoSanitari (MTS Group) and Merloni Elettrodomestici.

During the 1980s the company started manufacturing boilers.

During the 1990s the company opened its first branches in Eastern Europe and Asia. It also acquired Racold, India's largest water heaters' manufacturer, and opened its first wholly owned plant in China.

In 2001, Industrie Merloni acquired the heating and burner companies Chaffoteaux, Elco, Cuenod and Rendamax.

In 2005 Merloni Elettrodomestici changed its name into Indesit Company.
