Heating system

Heating systems were a type of armor enhancement available during the Galactic Civil War between the Alliance to Restore the Republic and the Galactic Empire following the Battle of Yavin. The system consisted of double-insulation and small, efficient heating elements that prevented the wearer from suffering in low temperatures and allowed them to survive in environments dozens of degrees below what would normally be tolerable. Heating systems could be installed in any sealable armor that covered the entire body, and were installed in the laminate armor of Imperial snowtroopers. Other models of heating system included Atlas Corp's DL-87 armor enhancement and the Min-Dal Company's Model 00 heating system.

Behind the scenes
Heating systems were first mentioned in the Star Wars: Edge of the Empire Core Rulebook released by Fantasy Flight Games in 2013. The same information was also included in the Star Wars: Age of Rebellion Core Rulebook released the following year by Fantasy Flight Games.
