With standard near-surface geothermal energy, boreholes up to 200 meters are drilled. The heat difference from that depth is only around 10-15°C, but that's enough to collect the energy to heat buildings.
Iceland has geothermal power plants going down 2.5km and with temperatures of ~250°C that produce electricity, not heat.
