The development of the European Heat Pump Network (EHPN) occured within the framework of three EU Projects (THERMIE, SAVE). Main objective of this information platform is to support the market penetration by dissemination of information on all aspects of heat pump technology.

The European Heat Pump Association represents the interests of the European heat pump industry on international level.

ASHRAE will advance the arts and sciences of heating, ventilation, air conditioning and refrigeration and related human factors to serve the evolving needs of the public and ASHRAE. ASHRAE develops several standards related to space heating and cooling.

For more than a decade, the Geothermal Heat Pump Consortium has been working to increase the awareness and use of geoexchange technology throughout the United States and the world.
