The iconic radiator thermostat from Danfoss turns 75 and it is smarter, more intuitive, and more energy-saving than ever before.
In 1943, the entrepreneur and founder of Danfoss, Mads Clausen, invented the world's first radiator thermostat, and 75 years later, the iconic radiator thermostat is more relevant than ever.
In Europe alone, there are more than 500 million manual and non-regulated valves mounted on radiators. If these were upgraded and replaced by newer radiator thermostats Europe's annual CO2 emissions could be reduced by 29 million tons. With a return on investment in just two years, Europeans would save 12 billion Euros and 130 TWh of energy per year.
The radiator thermostat is an integral part of the Danfoss' DNA and the most known and visible example of our technologies:
"The prototype of the world's first radiator thermostat was tested in my father's (Mads Clausen’s) office. It became the starting point for the world's first thermostatic valve for controlling the temperature in a living room. The actual marketing of the product began in 1952, when Danfoss launched the radiator thermostat as an application which saves money and increases comfort in centrally heated homes, and since then we have moved along extremely fast," explained Jørgen Mads Clausen, Chairman of the Board at Danfoss.
Since 1943, Danfoss has manufactured around 350 million radiator thermostats, thereby reducing 650,000,000 tons of CO2.
"It is a strong advantage for Danfoss that we have been on the market for so many years, and there is plenty of Danfoss DNA in our brand-new electronic radiator thermostats. A great example is the Danfoss Eco™ - recently recognized with two prestigious design awards; a Ret Dot and a Danish Design Award. Our founder Mads Clausen invented the leading technology within heat control including the intuitive rotational feature of the thermostat. We have transferred his knowledge and technology to our electronic thermostats fully in line with the demand and expectations of our consumers," commented Anders Barkholt, Vice President, Danfoss Radiator Thermostats.
