A new line of HFC based air-water heat pumps has been introduced, providing high level performance ratings, a SCOP (Seasonal Coefficient Of Performance see note) value of up to 3.38 and a ESEER (European Seasonal Energy Efficiency Ratio) in cooling up to 4.28. These values comply with the future EU Ecodesign regulation for heating products.
Variable speed compressors, pumps and fans, optimized heat exchangers, and advanced control algorithm all contribute to reducing energy consumption.
In addition, an innovative defrosting algorithm, replacing conventional method by outside air during positive temperature situations, can improve the SCOP by up to 12 %.
In total, the new line incorporating all possible improvements, can provide 22 % energy savings compared with the previous models.

Note : The SCOP is a new EU Ecodesign parameter to evaluate the energy efficiency of heat pumps. It replaces the COP rating (Coefficient of Performance) by addressing seasonal variations in the rating. More details are in Annex I of the Air Conditioners Ecodesign Directive.
