Comparison of Heat Sources
Anything that uses some sort of flame will give off Heat nearby, raising the Temperature of any players near it. This includes:

* The range is given in the in-game units. 800 units is about 2 and a half foundations. The closer you are to a fire source, the more insulation you get (given insulation numbers can be met when standing closely to the fire source).

The effects from multiple heat sources can stack. Consider the advantages and disadvantages when placing heat-generating structures close together.

Tip: Campfire and Standing Torch give the same hypo and hyperthermal insulation, so it is better to use Standing Torches when you decide to warm up in cold areas because they are cheaper to craft and consume less fuel.
