IMI HEIMEIER thermostatic valves achieve ‘A’ rating ​
Highest energy-efficiency rating awarded to HEIMEIER products 
Following extensive testing by the renowned consumer institute Stiftung Warentest, the IMI HEIMEIER range of thermostatic valves has been awarded the highest ‘A’ rating for energy efficiency. It means our products can be marked with the TELL (Thermostatic Efficiency Label) label, making it easy for customers to immediately identify the most energy-efficient products available on the market.
Energy-efficient thermostatic valves are seen as
​an important tool in the fight to reduce energy consumption and minimise environmental impact. It’s estimated that energy savings of up to 10% can be achieved using ‘A’ rated products, which rises to almost 20% when old-style radiator valves are replaced with ‘A’ rated thermostatic valves.​
Only products that fulfil the requirements of EN 215 standard are entitled to display the TELL label and they must have satisfied four key criteria:

  • Water Temperature Effect
  • Hysteresis
  • Closing Time
  • Differential Pressure Influence
