Heat pumps can be used to move heat around in a building. If the data center is directly adjacent to housing, this would be trivial to implement efficiently. The same system cooling the data center would be heating homes.
In the summer though, you’d have to push that heat to atmosphere, so this only helps in colder climates

This kind of district heating is not terribly uncommon. The question here is how hot can you get the water and if you have to ‘top it off’.
