HM Heizkörper is a brand of quality and innovations. H.M. Heizkörper GmbH & Co. KG Company was established in 1994 in Dingelstadt / Thüringen by Heinz Murr and his son Christian Murr as a family business of Dia-Therm Heizkörper Company.

Collectively, Murr family has been producing panel radiators since 1962. Apart from production sites in Germany, they also have plants in Yugoslavia, Ireland, China, and Turkey. This family company was one of the first to start automatized production of steel panel radiators, which was a revolutionary way of production at that time. Since then, Murr family has been continuously implementing innovations in this area which have always been oriented at an ordinary consumer and serial production.
