Last I checked waste heat isn't energy dense enough for large-scale district heating. Small pilot projects yes, but it won't heat whole towns.

Denmark would disagree, but with the limitation that the data centre needs to be sited in an appropriate location.

I don't think anywhere would want to be entirely reliant on a single datacentre, at least not at the scale of district heating use in Denmark.

(I gave some pages in Danish, you can search "Denmark datacentre district heat" yourself if you like.)

		These are future plans and they lack specificity. I don't think they will come to fruition. The problem is that waste water from data centers isn't hot enough.
