Heat Exchanger introduces an ability to extend the reach of heater by providing heat transmission network. Heat exchanger constantly attempts to normalize itself and all of it`s adjacent cells to contain same amount of heat via transference

It is not an ideal medium, however, as it can not account for ongoing heating or cooling.

Heat exchangers can leech an excess heat out of Generators, making them convenient mean of stringing up more generators to the same heating source.

Heat exchangers, however, can NOT leech any heat from Heat Sinks - any connection between those two allows only for one-way heat transfer, from exchanger into sink.
