Boiler — Factorio Production Calculator
Boiler is crafted in the assembling machine in 0.5 seconds, producing 1 per craft from 1 × Stone furnace, 4 × Pipe. At 60 per minute you need 1 assembling machine, and the chain behind it draws on 2 raw resources: stone, iron ore.
Production chain for 60 Boiler / minute
| Item | Per minute | Machines | Machine |
|---|---|---|---|
| Pipe | 240 | 4 | Assembling machine |
| Iron plate | 240 | 12.8 | Furnace |
| Boiler | 60 | 1 | Assembling machine |
| Stone furnace | 60 | 1 | Assembling machine |
Raw materials
| Resource | Per minute |
|---|---|
| Stone | 300 |
| Iron ore | 240 |
Machine counts are not rounded up. Add a little headroom in game — belt throughput and inserter speed usually mean you want 5-10% more than the exact number.
Boiler recipe
| Machine | Crafting time | Output | Ingredients |
|---|---|---|---|
| Assembling machine | 0.5 s | 1 | Stone furnace × 1, Pipe × 4 |
What the whole chain needs
60 boilers per minute pulls in 3 intermediate products, and the whole tree comes to 19 machines across 2 machine types, fed by 2 raw resources. The table above already sums demand across every branch — if copper cable is used by two recipes, you see the total, not one of them.
Belt check: the busiest input here moves 300 per minute, which is 0.33 of a yellow belt's 900 per minute. Above 1.0 and you need a second belt (or a faster tier) before the machines themselves become the limit.
What uses boiler
No base-game recipe consumes boiler — it is an end product. Once you build it, the chain stops here, which makes it a good target if you only want to size the sub-factory that feeds your mall.
What boiler is made from
- Stone furnace — 1 per craft
- Pipe — 4 per craft
FAQ
How many assembling machines do I need for 60 boilers per minute?
1 assembling machine. One at standard speed produces 60 per minute, so 60 ÷ that number is the count. The calculator above rounds nothing — add 5-10% headroom for belt and inserter losses in a real factory.
How much raw ore does boiler take?
At 60/min the chain consumes 300 stone per minute, 240 iron ore per minute. Those numbers are the theoretical minimum — mining productivity research and productivity modules both reduce them.
Machine counts assume bare machines at standard speed. Recipe data comes from the game's own prototypes (PlayerCalc, Factorio 2.0 base game). Not affiliated with Wube Software.
