Enhanced geothermal uses fracking to expose absolutely massive amounts of m^2 through fracking between two parallel, long, horizontally drilled bore holes. Current efforts seem to show a minimum of 30 years before there will be loss of heat quality.

The sorts of drilling talked about for enhanced geothermal are on the scale far far above the needs of a house, IIRC about 5MW per bore hole pair, with many connecting from a single point on the surface. It's also at distances kilometers into the earth.
