Study finds energy-saving potential

The Technical University of Dresden has released findings from their scientific study Analysis of the energy savings potential of replacing old thermostatic regulating valves.  

According to the study, heat transfer technology in Germany offers an annual savings potential of around 5 million tonnes of CO2.

Additionally, if all radiators in Germany were fitted with highly efficient thermostatic radiator valves, approximately 18 billion kWh of heat energy could be saved.

As part of the energy-efficiency renovation of buildings by replacing old thermostatic regulators with modern variants, heat energy can be reduced by up to seven per cent each year.

Approximately four million regulators are replaced every year in Germany. If the rate of replacement remains the same, the existing potential for energy saving and reduction will not be achieved for around 25 years.

Simple and reliable guidance for selective purchasing of energy-efficient products will increase environmental awareness among end consumers.

With the introduction of the first European classification system, TELL (Thermostatic Efficiency Label), by European valve manufacturers association EUnited Valves, an energy label has been created that gives a clear indication of the energy efficiency class of a thermostatic radiator valve.

TELL is the product classification scheme of the European thermostatic radiator valve manufacturers for the purposes of energy efficiency labelling, which provides for the consumers in Europe and worldwide for information and guidance in making a conscious purchasing decision, plus the industry´s desire to promote responsible energy usage.

EUnited Valves’ main areas of activity involve developing technical rules and guidelines, representing the interests of these industries towards the European Commission and exchanging ideas and information within the industry.
