Danfoss radiator thermostat celebrates 75 years
In 1943, the founder of Danfoss, Mads Clausen, invented the world's first radiator thermostat, the company notes. Seventy-five years later, the product is more relevant than ever in a world trying to control the temperature.
In Europe alone, there are more than 500 million radiators with manual and unregulated valves. If you installed radiator thermostats on them all, Europeans could save 12 billion euro and 130 TWh of energy every year. The upgrade would reduce Europe's annual CO2 emissions by 29 billion tons — and the investment would pay for itself in just years. That is according to a report from the European Building Automation Controls Association.
"The first prototype of the world's first radiator thermostat was tested in my father's office," recounts Jørgen Mads Clausen, chairman of the board at Danfoss. "It was the birth of the world's first thermostatic valve for controlling the temperature in a room. The actual marketing began in 1952, when the radiator thermostat was launched as 'a device that saves money and makes centrally heated rooms more comfortable,' and from there on it just took off."
The product was patented and gave Danfoss a leading position when the company began mass production of the radiator thermostat. Since 1943, approximately 350 million have rolled off Danfoss' production line. The latest version is the intelligent radiator thermostat Danfoss Eco — which has won the prestigious design awards: Ret Dot and Danish Design Award.
"It is a strength for Danfoss to have been on the market for so many years, and there is an abundance of Danfoss DNA and cultural heritage in even our brand new electronic thermostats," explains Anders Barkholt, vice president of Danfoss Radiator Thermostats. "Mads Clausen developed the leading technology in the temperature regulation and the intuitive turning motion of the thermostat that makes it so easy to use. That knowledge and technology has now been incorporated in all our new electronic thermostats. That way we keep up with trends in line with consumers' wishes."
