Heating capacity of an earth to air heat exchanger EAHE equipped with an exterior fan in the arid region like the Southwest of Algeria is investigated experimentally. In-situ measurement of annual undisturbed subsoil vertical temperature profile is shown that it was ۲۸°C at a depth of ۱.۵ meters. The EAHE made of ۶۶ meters of PVC tube is demonstrated a heating capacity of ۱۳°C and a cooling capacity of ۷°C and a big dependence on local climate conditions. Great potentials and thermal comfort with less energy consumption are represented by earth to air or air-ground heat exchanger in the arid regions like the South of Algeria.
