ostranauts manage my heat: Core Systems
Heat management in Ostranauts is part of a larger atmospheric and engineering system. Temperature is not isolated from pressure, gas composition, power, or equipment condition. A ship can look structurally sound while still containing a dangerous room, damaged conduit, or poorly controlled atmosphere.
Start by identifying whether you are managing a single cabin, an open salvage area, or several connected zones. A small ship may only need one thermostat for basic monitoring. A larger vessel benefits from multiple thermostats because different rooms can have different heating and cooling requirements.

| System | Main role | Heat-management priority |
|---|---|---|
| Thermostat | Tracks and helps regulate room temperature | High |
| Air pump | Moves or supplies atmospheric gases | High |
| Scrubber | Handles unwanted carbon dioxide | Medium |
| Oxygen bottle | Provides emergency oxygen | High |
| Battery | Powers ship systems | High |
| Conduit | Carries electrical power | Medium to high |
A thermostat is especially useful once your ship has multiple rooms. One device may be enough for an early layout, but expansion creates more zones and more opportunities for temperature differences. Install atmospheric controls where they can be monitored and serviced without forcing your character through unsafe areas.
Before changing equipment, activate the relevant heat or atmospheric overlay. Reading the ship’s condition first helps you avoid repairing the wrong system or entering a dangerous compartment unprepared.
Build a Reliable Heat-Control Setup
A reliable setup begins with information. Check the atmosphere, inspect the temperature, and confirm that the equipment responsible for the room is connected and powered. Do not assume that a room is safe merely because it has walls or because a nearby system appears intact.
The basic setup is easier to manage when each room has a clear purpose. A living area, salvage bay, engineering compartment, and storage section may not need identical conditions. Keeping zones understandable also makes later repairs faster.
Single-Zone Cabin
- One thermostat
- Simple gas control
- Easy to inspect
- Suitable for early layouts
Workshop Zone
- Multiple powered devices
- Higher repair attention
- Monitor heat before work
- Keep emergency oxygen nearby
Expanded Ship
- Several thermostats
- Separate atmospheric zones
- Clear access routes
- More demanding maintenance
Use the following setup order when configuring a new room:
Inspect the Room
Open the heat and atmosphere information before installing anything. Look for abnormal readings, smoke, toxic gas, missing walls, and damaged conduits.
Install or Repair the Thermostat
Add a thermostat to the zone that needs temperature monitoring. If you find a damaged unit during salvage, repair it before relying on its readings.
Confirm Power
Check batteries, conduits, and connected equipment. A temperature-control plan is not useful if the relevant system lacks power.
Balance the Atmosphere
Use the appropriate air pumps and gas sources for the room. Keep oxygen, nitrogen, carbon dioxide, and smoke information visible while making changes.
Recheck After Pressurization
Once the zone is enclosed and pressurized, inspect it again. A sealed room can reveal problems that were not obvious while the ship was open.
| Setup stage | What to inspect | Common mistake |
|---|---|---|
| Before installation | Heat, pressure, smoke, gas composition | Entering without checking overlays |
| During repairs | Thermostat, conduit, batteries | Ignoring damaged supporting systems |
| During pressurization | Oxygen level, room enclosure, pumps | Adding oxygen without considering ignition risk |
| After completion | Temperature stability and access | Assuming the room is safe permanently |
Pure oxygen may satisfy breathing requirements in some situations, but an oxygen-rich pressurized cabin can increase fire and ignition danger. Use a controlled gas mix for regular living spaces instead of treating emergency oxygen as a permanent solution.
Manage Heat, Pressure, and Gas Together
Temperature control works best when paired with deliberate pressure management. Ostranauts uses atmospheric conditions that can affect survival, work efficiency, and equipment safety. The goal is not simply to make a room warm or cold; it is to make the entire zone predictable.
A practical long-term target is a breathable, controlled atmosphere rather than an improvised bottle-based system. Nitrogen can serve as the main atmospheric gas, oxygen supports breathing, and a scrubber helps manage carbon dioxide. The exact arrangement depends on your ship design, available equipment, and current project.
| Atmospheric concern | Why it matters | Recommended response |
|---|---|---|
| Low oxygen | Reduces survival margin | Add oxygen carefully and monitor the reading |
| Excess oxygen | Raises ignition danger | Avoid using pure oxygen as a routine cabin mix |
| Carbon dioxide | Makes a zone unsafe over time | Use a scrubber and inspect its connection |
| Smoke | Signals a current hazard | Find the source before continuing work |
| Low pressure | Prevents a stable living space | Seal the room and verify pumps |
| High temperature | Can indicate equipment or zone problems | Use the heat overlay and inspect nearby systems |
When planning a pressurized room, complete the structure before committing to a final atmosphere. Installing floors and walls gradually is useful during ship expansion, but pressurizing an unfinished design can create unnecessary work. A cohesive room shape makes it easier to understand where doors, pumps, sensors, and crew areas belong.
For ships with several rooms, avoid placing every atmospheric system in a difficult-to-reach location. A thermostat that requires hazardous traversal to inspect is less useful than one positioned near a safe access route. The same principle applies to batteries and oxygen reserves.
Treat every enclosed room as its own maintenance problem. A ship can contain a safe cabin beside an unsafe workshop, so check the specific zone rather than relying on a general impression of the vessel.
Heat Overlay and Safety Checks
The heat overlay is one of the most valuable tools for preventing avoidable accidents. Use it before entering a derelict ship, before dismantling unfamiliar equipment, and after installing new systems. It can also help identify areas where another character may be present, allowing you to avoid walking into a dangerous encounter.
Temperature information should be part of your standard salvage routine. Do not wait until your character is already in trouble. A quick inspection takes less time than recovering from a fire, oxygen failure, or damaged suit.
Scan
Check heat, smoke, and atmospheric data before moving deeper into the ship.
Secure
Keep an emergency oxygen bottle available and confirm your battery situation.
Salvage
Remove valuable systems only after checking the surrounding hazards.
Return
Recheck your own ship after installation, repairs, or major layout changes.
| Situation | First check | Safer action |
|---|---|---|
| Entering a derelict | Heat and occupant indicators | Pause and scan before approaching |
| Removing conduit | Damage and fire risk | Restore or replace questionable parts |
| Installing a reactor component | Heat, power, and clearance | Build a controlled engineering area |
| Pressurizing a room | Walls, doors, gas mix | Seal the zone before filling it |
| Expanding the ship | New room boundaries | Add monitoring and access before crew use |
Regular restoration is also part of heat safety. Damaged systems can deteriorate and require replacement components, increasing operating costs and creating more failure points. Restoring salvage before installation can reduce the chance of problems while you are rebuilding the ship.
The best time to use the heat overlay is before a hazard becomes urgent. Make scanning a routine part of salvage, repair, pressurization, and ship expansion.
Maintenance Priorities and Expansion Planning
Heat management becomes more demanding as the ship grows. More rooms mean more surfaces to seal, more systems to power, and more locations where a thermostat or air-control component may be useful. Expansion should therefore follow a maintenance plan instead of happening only when spare parts are available.
Prioritize systems that protect life and preserve control over the ship. Emergency oxygen, batteries, thermostats, air pumps, scrubbers, and conduits all contribute to a stable working environment. Valuable salvage can wait if carrying it would prevent you from taking critical construction components.
A useful maintenance cycle looks like this:
- Restore damaged components before installing them whenever practical.
- Keep spare oxygen available for unexpected pressure problems.
- Check battery charge before long salvage operations.
- Inspect conduits after moving heavy equipment.
- Revisit each pressurized zone after major construction.
- Add crew only after the ship has a dependable breathable area.
Heat and Atmosphere Checklist:
- Inspect the heat overlay before entering an unfamiliar ship section
- Repair or install a thermostat in each important atmospheric zone
- Confirm batteries, conduits, pumps, and scrubbers are connected
- Avoid treating pure oxygen as a routine cabin atmosphere
- Recheck pressure and temperature after expanding the ship
| Priority | Component or task | Reason |
|---|---|---|
| 1 | Battery and power access | Controls whether critical systems can operate |
| 2 | Thermostat and sensors | Provides temperature awareness for each zone |
| 3 | Air pumps and gas supplies | Supports controlled pressurization |
| 4 | Scrubber | Helps manage carbon dioxide |
| 5 | Structural expansion | Creates safer, more predictable living space |
For current game updates and patch information, consult the official Ostranauts Steam page as of 2026-08-04. Patch changes can affect interface behavior, restoration risks, and other engineering details, so verify major mechanics after updates.
Do not install random floors and walls just to increase size. Salvage the construction style you intend to keep, then build a coherent layout that leaves room for safe access, atmospheric control, and future crew areas.
FAQ: Ostranauts Heat Management
Q: How do I manage heat in Ostranauts?
Start with the heat overlay, then inspect the thermostat, power connections, room boundaries, and nearby atmospheric systems. Heat should be managed together with pressure, gas composition, smoke, and equipment condition.
Q: Do I need more than one thermostat?
A small ship may function with one thermostat, but multiple rooms can require separate temperature monitoring. Adding thermostats becomes more useful as you create independent zones for living, salvage, storage, or engineering.
Q: Is pure oxygen safe for a pressurized room?
Pure oxygen can support breathing in some circumstances, but it can increase ignition danger around powered or damaged equipment. A controlled nitrogen-and-oxygen atmosphere is a safer long-term approach for ordinary cabins.
Q: Why should I use the heat overlay while salvaging?
The overlay can reveal dangerous heat, smoke, and possible hazards before you move deeper into an unfamiliar ship. It also helps you inspect your own vessel after repairs, installations, and structural expansion.
Stable temperature is only one part of a safe ship. Pair heat monitoring with reliable power, controlled gas levels, intact structure, regular restoration, and cautious expansion.
