De Dietrich S.A.S.

A symbol of quality since 1778, the De Dietrich logo is the world’s oldest known industrial trademark. Our company can date its creation all the way back to 1684. Today, it forms part of one of the largest industrial groups specialising in thermal comfort: BDR Thermea The De Dietrich floor-standing boiler offering comprises boilers that run on oil, gas or solid fuel (wood or wood pellets). Floor-standing boilers can also be used with renewable energy sources, heat pumps or solar installations. Combined with solar installation, heat pump or wood renewable energy, the condensing boiler is one of the most economical and environmentally respectful versions available. The company logo still features a hunting horn, as a reminder to the royal decree issued by Louis XVI to protect De Dietrich products from counterfeits.
