Geothermal Heat Pump

The Geothermal Heat Pump is a building whose output depends heavily on the initial temperature of the material fed into it. In practice, this means the building’s result is not fixed; the state of the input matters just as much as the building itself.

Because of this, it is best treated as a temperature-sensitive processor rather than a guaranteed-output machine. When planning a setup around it, the important variable is the starting temperature of whatever you supply, since that temperature strongly affects what comes out.
