Heat pumps – quality label

The EHPA (European Heat Pump Association) quality label for heat pumps originates in activities of the heat pump associations of Austria, Germany and Switzerland (D-A-CH quality label) to protect the market from sales and installation of low-quality heat pumps and to create a common set of requirements to ensure product and service quality for heat pumps.

Certified products were in the past subsequently labelled ‘Wärmepumpen Gütesiegel‘ or the quality label for German speaking countries.

The idea has been further developed in the European Heat Pump Association which now unites 21 countries, or national heat pump associations and the country scope has been extending.

In order to reflect this development, the D-A-CH quality label has been gradually replaced by the EHPA Quality Label (EHPA-QL). In addition to the founding countries the EHPA Quality Label was introduced in Sweden, Denmark, Finland, France, Ireland and in 2010 also in the Czech Republic and Slovakia. The Czech Heat Pump Association, as a founding member of EHPA, created according to the EHPA rules a national commission, which is empowered to award a quality label valid in the Czech Republic. The label can be granted to standardized space heating electrically-driven heat pumps, with or without domestic hot water heating capability, with a capacity up to 100 kW from air, geothermal or water heat sources.

  • it provides consumer protection ensuring them that the labelled product has guaranteed quality parameters, it uses the most up-to-date technologies and provides constantly improving long-term advantages.
  • it provides compelling arguments (institutional and financial) to all institutions and investors seeking to use governmental grants.
  • it supports the current concept of heat pumps as an energy-efficient, reliable and high quality products.
  • it supports the inclusion of the heat pump in innovative technology for obtaining renewable external heat which is environmentally friendly.
  • it helps protect existing heat pump market against poor quality products.
