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.
There is no way to tell yet what the longevity of the resource will be as it's too early. In fracked resources the main issue is "short circuiting" where increased flow rates travel along preferential paths between the doublet wells as the source rock cools and cooling rate of the source rock in general. This causes the MWt of the resource to decline per injection / production well. Fervo is getting around this by drilling extra wells per pad to be turned on in response. Many geothermal resources decline over time as heat is slowly extracted and these declines are somewhat manageable by tuning the injection production well rates and drilling new wells. They are built into the economics of existing plants. Geothermal is kind of extractive and not "renewable" in this way over medium term time scales, you need to continuously keep drilling at a certain rate. Rock is a good insulator and it takes a long, long time for it to heat back up.
