There are attempts to use data center waste heat for domestic heating, but that is not easy at all.
Data center waste heat is around 50 C at most, often less, so you can use it to drive a heat pump, but you can't transport it very well.
If you transport it, it still has to be used very locally. Data centers are often not built on expensive ground close to where people live, though.

People need heat in winter. Not in summer.
What are you doing in summer?
What are you doing in winter, if the need for this data center happens to be low and it does NOT produce sufficient waste heat?
You just built a tight coupling of one piece of critical infra with another piece of critical infra. This is usually not a winning strategy.
