In 2012 Vaillant launched their second generation of gas heat pump “zeoTHERM” to the European market. Since 2009 several zeoTHERM gas heat pump systems have been operating and analyzed as part of a field trial organized by Germany’s “IGWP” (initiative for gas heat pumps in Germany). This report shows the results of the field trial as well as the relevant solar simulations. The total system efficiency was proven to be 35% higher than a “state of the art” heating systems with a wall hung condensing gas boiler. The Vaillant zeoTHERM heat pump system was also proven to be extremely reliable and robust. Since 2010 zeoTHERM has been manufactured in series production and has been freely available in the trade.
