Not really, it’s only useful if you intentionally capture it at the point of heat and Transfer that in a liquid still hot to take it a central point, by the time the fans cool of and the heat is pumped out the building it’s too dispersed to use. Unless you’re in a cold area and low grade heat can be used for warming.

You can have a complex of multiples though and they to congregate near each other for short interconnection.

No one uses in ground heat pumps, especially not existing units where you have to dig up the yard, but regular air source heat pumps are still good enough by far.

I expect that we will get in orbit refueling to extend their life once you get a good nuclear and solar panel power tug with an electric thruster that can deliver fuel, they’re in a similar orbit if you just do that.

Small means they can be cooled down quickly and easily and usually the modern ones can do it passively without needing power for these very small ones.
