Managing temperature stability is essential for smooth colony development in Oxygen Not Included. The thermal regulator helps players control heat exchange between pipes and the surrounding environment, preventing dangerous temperature spikes or dangerous overcooling.
This guide covers how the thermal regulator works, how to integrate it into automation, and how it fits into broader thermal planning for your base.

How Thermal Regulators Work
The thermal regulator behaves like a thermal switch that can disconnect pipe contents from ambient temperature. When toggled off, it acts as an insulator, blocking heat transfer and preserving the temperature of whatever fluid or gas is inside the pipe.
Because each tile has a fixed heat capacity, turning the regulator off at the right moment can lock heat in place, which is useful for freezing geysers or protecting sensitive machinery from warm airflow.
Automation and Wire Control
Using wire signals, players can link thermal regulators to sensors, timers, or logic circuits. Setting the regulator to turn on only when a pipe network reaches a specific temperature ensures that heat is retained precisely when needed.
Combining temperature sensors with memory state logic allows you to create self-regulating loops that respond dynamically to seasonal changes or industrial heat spikes.
Practical Integration in Base Design
Placing thermal regulators near steam vents, coolant loops, or machinery clusters gives you fine-grained control over thermal distribution. You can isolate hot pipes during the day and allow heat to bleed off at night to manage base-wide temperature averages.
Heavy use of insulated tile around regulated pipes further reduces unwanted dispersion, making your thermal management system more efficient and predictable.
Performance Under Extreme Conditions
During heat events such as meteor showers or polluted oxygen blooms, thermal regulators help stabilize critical zones. By cutting off conductive paths, they protect delicate automation and prevent pipes from becoming unintentional radiators.
Paired with active cooling or steam turbines, a well-designed regulator network can keep base temperatures within safe operating ranges even in harsh environments.
Optimizing Thermal Layouts
- Reserve insulated tile for critical regulator branches to minimize lateral heat loss.
- Use temperature sensors to trigger regulators instead of manual wiring for long-term stability.
- Group high-heat machines behind a single regulated segment to reduce wiring complexity.
- Test regulator behavior during seasonal shifts to ensure your loops remain balanced year-round.
FAQ
Reader questions
Does turning off a thermal regulator actually stop all heat transfer?
No, turning it off greatly reduces conductive heat flow, but gases and liquids inside the pipe can still exchange heat with adjacent materials through small leakage paths and radiation.
Can a thermal regulator be automated based on pipe temperature?
Yes, you can wire it to a temperature sensor or switch so that it turns off when the pipe reaches a chosen threshold, allowing you to preserve heat or cold automatically.
What happens if a thermal regulator is placed in the middle of a long pipe?
The segment on the off side will thermally decouple from the rest of the loop, maintaining its current temperature while the other side continues to respond to external heat sources.
Is the thermal regulator affected by the material of the pipe itself?
The pipe material determines baseline heat capacity and conductivity, while the regulator controls whether that heat can flow through its tile, so both properties matter for overall performance.
