Converting current infrastructure to accommodate that might not be very feasible. But planning future projects with this in mind is completely reasonable. We already have a data center in Helsinki that's providing heating for up to 20 000 apartments.

In Finland we do have a pretty efficient way of transporting heat. It's called district heating and plenty of houses in larger towns are getting their heating through that. Basically it's very well insulated water pipes going around the city. Actually 46 percent of residential and service buildings in Finland are heated by that.
