Boilers are large, corpulent Infested riddled with pulsating boils, which launch an Infested seed occasionally. When killed, it will burst and launch several Infested seeds that grow into spawn pods. Left unchecked, these spawn pods unleash a variety of smaller Infested to overwhelm their enemies.
- Boilers waddle into moderate range of a player and create 3 to 5 spawn pods around themselves once they are killed.
- Once grown on the ground, spawn pods gestate for several seconds before bursting, randomly spawning single or multiple Chargers, Volatile Runners, and Leapers.
- Spawn pods can be destroyed before gestation is complete.
- All the gestation products will be at level 10 no matter what, regardless of the rank of the Boiler.
- Boilers, similarly to other Ancients, can extend one of their arms to reach their targets at longer ranges.
- It is possible to farm a large amount by leaving hives in "Hive" missions and letting them spawn, only destroying the Hive once no more are spawning.
- Boilers under Mind Control will release pods that spawn hostile infested units when damaged or upon death. It is unknown if this is intended.
- Boilers are one of the few enemy types (along with the Charger, Brood Mother and Maggot) that cannot be cut in half by Slash damage.
- Boilers seem to only attack the player, if they have been attacked, though they will still run up to the player on sight.
A special variant of the Boiler can be found in the final mission of the Stolen Dreams quest. Apart from having more hitpoints and its pus being colored blue instead of orange, it is otherwise identical to the standard Boiler.

- Boilers have no ragdoll, and thus cannot be affected by Nekros ' Desecrate.
- On previous versions, the Boiler Eximus Codex page displays the same codex as the regular Boiler, however all Eximus Boiler variants are stuck within each other to the right of the regular Boiler.
- Boilers will often fly straight up into the air for no reason, often when hitting enemies or being pushed up by enemies.
