Heat creeps

Every machine adds heat. In a sealed base it accumulates, so plan cooling before you pack machines together.

Wheezeworts first

Wheezeworts are free, slow cooling. Use them on small hot spots while you design a real loop.

The aquatuner loop

A liquid cooling loop moves heat out of a room and dumps it into a cold biome or the void.

Protect the food

Farms and hatcheries hate heat. Keep them in the cool zone so your food chain does not cook.

Insulate the gap

Insulated tile stops heat from walking into the living quarters next door.

Build the loop

The building database lists aquatuners, pipes and vents. Place them on a clean cooling run.

Cool the power

Generators run hot. Move them off the living grid or the whole base warms up.

Watch the sensor

A temperature sensor triggers cooling only when needed. Automation saves the power the loop would waste.

Keep critters cool

The critter database shows species that suffer in heat. Ranch them where the loop reaches.

Move the generators

Power machines run hot. Shift them off the living grid or the whole base warms up with time.

Use a sensor

A temperature sensor starts cooling only when called for. Automation spares the power the loop would burn.

Shelter the species

Some critters wilt in heat. Ranch them where the cooling loop reaches them.

Frequently asked questions

Why does my base overheat?

Machines and refineries emit heat that builds in a sealed base. Without cooling, food and duplicants suffer.

How do I cool things?

Wheezeworts for slow help, and a liquid-pipe cooling loop for serious heat. Move heat to a cold biome or space.
