- Sandustry move lava setups work best with a stable pool and thermal buffer blocks.
- Surface area helps lava act as a longer-lasting heat reservoir during demand spikes.
- Thermal buffers distribute heat between the lava source and nearby refinery machinery.
- Contained heat zones reduce temperature swings and make production easier to monitor.
Sandustry move lava: What the Setup Solves
Sandustry treats heat as part of factory logistics rather than a simple machine bonus. A refinery can stall when its temperature falls during a demanding reaction, even if the rest of the production line has plenty of materials. The practical answer is to move heat through a controlled thermal zone instead of relying on a small, direct source beside every machine.
The strongest layout uses a lava pool, a connected run of thermal buffer blocks, and the refinery equipment that needs consistent heat. Lava or lit cinder trapped in a suitable filter can provide a steadier source than a point burner, while the buffer creates a broader distribution network.
Video Highlights:
- Lava pools can serve as stable heat reservoirs for production lines.
- Thermal buffer blocks help distribute stored heat across a factory zone.
- Large factories benefit from designing around temperature stability.
- Thermal planning can reduce interruptions caused by sharp heat drops.
Lava Pool
- Stable heat source
- Broad surface area
- Useful near multiple refineries
Thermal Buffer
- Stores and distributes heat
- Smooths demand spikes
- Connects source to machines
Thermal Zone
- Keeps equipment together
- Easier temperature checks
- Supports modular expansion
Build the heat source as part of the factory plan. Placing a lava pool after machines stall usually creates longer rebuilds and awkward rerouting.
| Component | Primary role | Best placement |
|---|---|---|
| Lava pool | Supplies steady thermal energy | Near the center of a processing zone |
| Thermal buffer blocks | Stores and distributes heat | Between the pool and refinery machines |
| Containment or filter structure | Keeps hot material controlled | Around the lava source and transfer path |
| Refinery line | Uses the delivered heat | Along the warm side of the buffer network |
How to Move Lava Safely and Consistently
Moving lava is less about forcing a fast transfer and more about controlling where heat can spread. Start with a contained source, then extend the thermal path toward the machines that need it. A pool with more exposed area provides a more dependable reservoir than a tiny isolated pocket, especially when several refineries draw heat at once.
Use the following sequence when creating a new thermal route:
Choose the Thermal Zone
Group the refineries, burners, and related processing machines that need similar temperatures. A compact zone reduces the length of the transfer path and makes temperature changes easier to diagnose.
Create a Contained Lava Pool
Place lava or lit cinder inside a controlled structure. Give the pool enough surface area to act as a reservoir, but avoid placing it where ordinary material flows can enter and create a blockage.
Extend Thermal Buffer Blocks
Connect the pool to the processing area with thermal buffer blocks. Treat this path like a heat distribution network, not a decorative wall; it should touch or closely support the machines requiring heat.
Test During Peak Demand
Run the line while multiple machines are active. If temperatures fall sharply, enlarge the pool, add buffer capacity, or shorten the distance between the source and the highest-demand equipment.
The goal is a stable thermal gradient from the lava reservoir to the refinery line. A short, connected path is usually easier to maintain than a thin route stretched across several unrelated production areas.
| Setup choice | Strength | Risk | Recommended use |
|---|---|---|---|
| Small direct source | Quick to place | Temperature drops under demand | Early testing or one machine |
| Large lava pool | Better heat stability | Needs careful containment | Multi-machine refinery zones |
| Pool with buffer blocks | Stable distribution | Requires planning space | Main thermal infrastructure |
| Long isolated route | Reaches distant machines | Harder to diagnose and expand | Temporary routing only |
Do not let ordinary sand, slag, or mixed flows enter the lava route. Heat infrastructure should remain isolated from material logistics so a production jam does not become a thermal failure.
Thermal Buffer Design for Factory Expansion
A good lava route should survive expansion without forcing you to rebuild the entire factory. Reserve space beside the buffer network for additional refineries, filters, and processing modules. This is especially valuable when production changes from a single reaction to several parallel reactions with different material demands.
Build the system in repeatable blocks:
- Source block: the contained lava pool and its access structure.
- Buffer block: thermal blocks that hold and spread heat.
- Machine block: refineries arranged along the warm transfer path.
- Inspection block: open space for checking flow, temperature, and jams.
- Expansion block: reserved room for another machine or buffer segment.
| Expansion concern | Practical solution | Result |
|---|---|---|
| More refineries | Extend the buffer in a straight branch | Easier modular growth |
| Uneven heating | Move high-demand machines closer to the source | Fewer cold spots |
| Limited floor space | Use vertical or diagonal logistics nearby | Better use of factory volume |
| Frequent maintenance | Keep inspection gaps beside the route | Faster repairs |
| Mixed material traffic | Separate conveyors and thermal structures | Fewer cross-system jams |
Launchers can help with vertical and diagonal logistics when the thermal zone must connect to another floor. Their trajectory can move items between levels without covering the entire factory in stairs or elevators. Keep that item route separate from the lava infrastructure; vertical transport solves material movement, while the buffer solves heat movement.
Copy a working thermal module instead of improvising every extension. Consistent spacing and repeated buffer patterns make temperature problems easier to identify.
A modular layout also makes upgrades safer. When a line needs a higher processing tier, preserve the existing flow direction and upgrade the machine or route in place where possible. Rebuilding around a stable lava pool is usually less disruptive than moving the source after every expansion.
Troubleshooting Lava Movement and Heat Loss
When a refinery stalls, inspect the thermal system before adding more machines. A larger production line cannot compensate for a heat route that repeatedly cools down or distributes energy unevenly. Check the source, the buffer, and the machine position in that order.
| Symptom | Likely cause | Adjustment |
|---|---|---|
| Refinery temperature fluctuates | Source is too small or too distant | Increase pool area or shorten the route |
| One machine stays colder | Uneven buffer contact | Reposition it closer to the main thermal path |
| Heat works until expansion | Buffer capacity is undersized | Add another buffer segment before adding machines |
| Lava route becomes blocked | Material flow entered the thermal zone | Improve containment and separate logistics |
| Production stops during spikes | Reservoir cannot meet simultaneous demand | Use a larger pool and broader buffer network |
Use this diagnostic order:
- Check the lava pool. Confirm the source is still contained and has enough exposed area.
- Check the thermal path. Look for missing connections, isolated blocks, or unnecessary distance.
- Check machine demand. Several active refineries may draw more heat than the original design expected.
- Check material separation. Dense materials can pile up and create unrelated bottlenecks near the thermal zone.
- Check the flow height. Restricting critical material feeds to about one block can prevent sinking particles from locking the line.
The one-block flow principle matters because dense materials such as gold and slag naturally settle beneath lighter particles. If a feed pile becomes too deep, the lower layer can stop the rest of the mixture. Thermal equipment may appear to be failing when the real issue is that the refinery is no longer receiving a consistent feed.
Change one variable at a time. Test the source, then the buffer, then the feed line so you can identify the actual bottleneck instead of masking it with extra machinery.
Lava Setup Checklist:
- Contain the lava or lit cinder source
- Give the pool enough surface area for demand
- Connect the source with thermal buffer blocks
- Keep material conveyors separate from heat infrastructure
- Test the route with all target refineries active
Best Practices and Sandustry move lava FAQ
A reliable thermal system is built around stability, separation, and repeatability. Avoid treating lava as a temporary patch for a cold machine. When the pool and buffer are part of the original factory plan, they support cleaner production lines and simpler future upgrades.
| Priority | Best practice | Why it matters |
|---|---|---|
| 1 | Stabilize the source first | A weak reservoir undermines every downstream machine |
| 2 | Use buffer blocks between source and machines | Heat becomes easier to distribute and maintain |
| 3 | Separate heat from item flow | Jams and contamination are easier to prevent |
| 4 | Keep high-demand machines nearby | Shorter routes reduce uneven heating |
| 5 | Expand in modules | Repeated layouts simplify upgrades and repairs |
Before finalizing the build, confirm that the thermal route remains accessible, the lava pool is protected from unrelated flows, and the refinery line can be expanded without crossing the main logistics network. A clean design usually outperforms a crowded one because every failure point is visible.
Q: What is the best way to move lava in Sandustry?
Use a contained lava pool connected to thermal buffer blocks, then place the target refineries along the distributed heat path. The system is designed around stable heat transfer rather than a rushed one-time move.
Q: Why does my lava-powered refinery keep losing temperature?
The source may be too small, too far away, or unable to meet simultaneous demand. Increase the pool's surface area, add buffer capacity, or move high-demand machines closer to the source.
Q: Should lava share a route with sand, gold, or slag?
Keep lava and thermal structures separate from ordinary material flows. Dense materials can settle and create jams, while contamination makes both logistics and heat problems harder to diagnose.
Q: Can this setup support a larger factory?
Yes. Reserve expansion space beside the buffer network and extend the system in repeatable modules. Test the route with multiple refineries active before adding another production branch.
Design the lava pool, buffer path, and refinery placement together. Stable thermal infrastructure gives every later production upgrade a stronger foundation.
