Yet further proof of OCHSNER's technology leadership was confirmed a few weeks ago by the Heat Pump Testing Centre Buchs (Switzerland). Record COPs of 4.4 (EN14511) and 4.7 (EN255) respectively were measured for a heat pump of the GMLW 14 plus* (heat source air) Series. You can find the results on the WPZ hompe page under www.wpz.ch.
