System Heat

System Heat is a comprehensive thermal management mod for Kerbal Space Program that completely overhauls how spacecraft handle heat. Instead of the stock system, it introduces Heat Loops where coolant flows between heat-producing parts (reactors, drills, converters) and heat-consuming parts (radiators). Each component has specific Output Temperature and Output Flux values that must be balanced. Design spacecraft with proper thermal architecture to prevent overheating during long missions. Features detailed UI overlays showing heat flow throughout your vessel.
