En effet, elles puisent la chaleur dans le sol ou les eaux souterraines, qui sont \u00e0 une temp\u00e9rature relativement constante tout au long de l'ann\u00e9e \u00e0 une profondeur d'environ 2,5 m. Le diff\u00e9rentiel de temp\u00e9rature est donc plus faible, ce qui permet un meilleur rendement. Le diff\u00e9rentiel de temp\u00e9rature est donc plus faible, ce qui se traduit par un meilleur rendement. Les pompes \u00e0 chaleur g\u00e9othermiques ont g\u00e9n\u00e9ralement un COP de 3,5 \u00e0 4,0 au d\u00e9but de la saison de chauffage, ce COP diminuant au fur et \u00e0 mesure que la chaleur est puis\u00e9e dans le sol. En contrepartie de cette am\u00e9lioration des performances, une pompe \u00e0 chaleur g\u00e9othermique doit \u00eatre \u00e9quip\u00e9e d'un syst\u00e8me de chauffage et d'un syst\u00e8me d'\u00e9vacuation des eaux us\u00e9es. <a href=\"https:\/\/www.china-heatpump.com\/fr\/dc-inverter-geothermal-heat-pump-with-high-cop-9-7\/\">pompe \u00e0 chaleur g\u00e9othermique <\/a>est plus co\u00fbteuse \u00e0 installer car il faut creuser des puits ou des tranch\u00e9es pour y placer les tuyaux qui transportent le fluide caloporteur. Lorsqu'elles sont compar\u00e9es les unes aux autres, les pompes \u00e0 chaleur sur nappe phr\u00e9atique sont g\u00e9n\u00e9ralement plus efficaces que les pompes \u00e0 chaleur utilisant la chaleur
