{{Info|The '''heater''' is a device that can be used to raise the [[temperature]] in a room.}}

Constructing a heater requires [[Research#Electricity|Electricity]] to be researched, which [[Scenario_system#New_Tribe_vs_New_Arrivals|New Arrivals]] start with. It requires {{Required Resources}} and is constructed in {{Ticks|{{P|Work To Make}}}}.

Heaters are placed on the floor. Unlike most objects, they can't be rotated, but can be uninstalled. A [[power]]ed heater will warm up an enclosed room up to the target temperature, ignorant of placement. A heater in the corner of the room is as effective as a heater placed in the center. The heat naturally spreads throughout rooms, sped up by open [[door]]s or [[vent]]s. One heater can only warm so much, and factors like room size may make the target unreachable - see [[Temperature]] for more details.

Heaters have two states of power consumption: high and low.  

*A heater that is actively heating consumes 175W (high power).

*If the target temperature is reached, a heater consumes 17 W (low power).

As heat constantly spreads to colder surroundings, heaters often remain at high power. If you have multiple heaters in a room, you can exploit this by having each one be 1 degree higher than the last - one will actively heat the room, while the others will be in low power state.

Heaters are very helpful in cold biomes, and useful in temperate biomes during winter or a [[cold snap]]. If a pawn is too far below their [[Minimum Comfortable Temperature]], they are vulnerable to the potentially lethal [[Injury#Hypothermia|Hypothermia]] and [[Injury#Frostbite|Frostbite]], and receive the [[Mood#Cold|''Cold'']] negative [[mood]]let. Warm [[clothing]] like [[parka]]s instead increase the comfortable temperature range, but clothes must be fitted for every pawn. A colonist sleeping under {{Temperature|16}} gives them the -4 [[Mood#Slept_in_the_cold|''Slept in the cold'']] moodlet, regardless of warm clothing.

Heating is necessary to grow [[crop]]s outside of their growing season. As heaters require an enclosed and [[roof]]ed room to function, a [[sun lamp]] must be used to provide light. This is the only way to grow crops in extreme [[biome]]s like an ''ice sheet''. [[Hydroponics]], combined with a heater and sun lamp, may be used to grow crops where there is no soil.

If resources and/or electricity are unavailable, a [[campfire]] may be used instead. They are much less wood efficient than multiple heaters and a [[wood-fired generator]], and their temperature can't be controlled, so pawns may instead be disgruntled by the heat.
