The construction of the second heating hub went very smoothly, but even after completion, this heating hub cannot immediately be put to use like the first one.
Due to limitations from the return water well below that injects water underground, this heating hub cannot directly extract geothermal energy. It can only rely on the heat water delivered via pipeline from the first heating hub at the train station to function.
As for whether the heat water extracted from the first heating hub, after its own evaporation loss and pipeline transport, can still supply the second heating hub, that depends on the total amount of heat energy carried by the groundwater extracted from the first hub.
