The presentation shows both different geothermal installation configurations: shallow and ground source. In each case, heat pumps characteristics and methods are described. A reference to European heat pump market is done and also the place that these devices take in the EU RES-Directive.

This paper explains the operation of the geothermal system in closed circuit in CIM Azterlan, Durango (205 kW); goals to be achieved, drillings and pilot tests, characteristics of the facility and the first results.

La presentación nos explica el funcionamiento del sistema geotérmico en circuito cerrado de C.I.M. Azterlan, Durango (205 kW); los objetivos que se quieren alcanzar, los sondeos y pruebas piloto, características de la instalación y los primeros resultados obtenidos.

The ASTECH project has set for objective to promote and disseminate Advanced Sustainable Energy Technologies for Cooling and Heating applications. The present publication provides this demonstration by describing exemplary realizations contributed by several project partners.
- Efficient solar building (Austria)
- 4 Solar assisted air-conditioning systems (Germany and France)
- Wood fuelled heating station (Bulgaria)
- 2 Ground source heat pump systems (Spain and Hungary)
