Heater is an infrastructure structure in Palworld.
It's a tier 17 Technology item and requires 2 points to unlock.
Overview[]
Heaters require a pal with Kindling. The level most likely does not matter, as far as I see. Heaters, like coolers, are used to help with incubating Pal Eggs in an Egg Incubator and provides a safer alternative to campfires. While heaters are more efficient in that they induce more heat than a campfire, keep in mind they have a smaller heating radius. It can also help keep you warm in an arctic base, although the small radius makes only the Electric Heater viable. Useless if you don't live there at high levels due to the Electric Egg Incubator.
