That Reykjavik doesn’t use energy to make heat; it uses it to pump it from A to B.

In addition, I guess the heat it pumps is geothermal (FTA: The new setup is expected to provide over 40 GWh/year of free ocean heat.)

A benefit of using this kind of reactor might be that the source of heat could be moved closer to where it’s needed, If so, but I don’t expect that to offset the advantage of the current heat source giving you heat for free.
