Heat Sink

Stores reclaimed exhaust heat.

Four Heat Sinks stacked in a stove's middle column are the whole of what stores its heat: look at one to read the core's current temperature. They take exhaust's heat while the stove is charging and give it back to the air while it is blowing, and a stove built without all four will not complete at all. See Hot blast for the charge and discharge rates and why a charged stove cannot be banked for later.
