Frostpunk 2 tech tree – All Heating Ideas, listed

The Frostpunk 2 tech tree (or officially, the Idea Tree) features a total of 142 Ideas spread across six tabs. At the start of each campaign, the Ideas on the outer branches of the tree are hidden. This guide lists every idea on the Heating tab, including the hidden ones.

Ideas relating to Heating are among the most important in Frostpunk 2, as you’d expect from a game that takes place during an ice age. This tab is where you’ll find technologies that allow you to upgrade your generator, to use Heat more efficiently, and to extract fuel deposits at higher rates.
