You're omitting a very important point: the heat sources themselves. The heat for the entire city doesn't come from a single power plant. It is distributed over many heat generation plants throughout the city, some dedicated solely to district heating. I don't think any spot on that map is more than a few km from a heat source.

To be fair, the vast majority of Helsinki's district heating system is powered by three combined heat and power (CHP) generation plants in Vuosaari, Hanasaari and Salmisaari. You're right that there is also 11 dedicated water heating plants to supplement the CHP supply in very cold weather or times of high demand, but they are supplementary.
