René Teurquetil is a discreet person, a hard worker, who has built the Muller Group over the years. Starting point was the family household appliance repair workshop in the early 1950s. The voltage change, from 110 to 220w, requiring the modification of the home appliances, is a new challenge for the company. Creation of the Companies Muller & Co and Teurquetil & Co, construction of the first factory at Fismes (Champagne region). After having developed a similar activity in the gas field, René Teurquetil is looking for new markets. In 1970, the Noirot Company, specialized in electric heating appliance is purchased. A new factory is built in Laon. Quality products bringing real benefit in terms of comfort and energy consumption are privileged.

Over the years, the Muller Group expands through a series of acquisitions: Camp, from 1978, promotes quality radiant heaters, Applimo in 1979, Auer in 1982 (gas appliances), Chaufelec , Airelec and, more recently, France Energies for the renewable energies. The leading policy is to maintain the identity of each trademark while reinforcing their industrial and technical means.

The Group expands abroad: creation of the Convectair branch in Canada and purchase of the Nobo Company in Norway. Innovation and quality obsession, generated by René Teurquetil, has led the Muller Group, through the Gifam professional syndicate, to move the energy efficiency standards towards a high level of requirement.
