BALTIMORE — In 1943, the founder of Danfoss, Mads Clausen, invented the world's first radiator thermostat. Seventy-five years later, the iconic product is more relevant than ever in a world trying to control the temperature.
In Europe alone, there are over 500 million radiators with manual and unregulated valves. If radiator thermostats were installed on all of them, 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 two years, according to a report from the European Building Automation Controls Association.
