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.
To make it easier to plan your path through the Heating tab of the Idea tree, I’ve taken a screenshot of the Heating tab with all of the hidden branches revealed, and listed all of the Ideas within each Heating category, along with a brief description of what effects that Idea has and what it unlocks.
All Heat tab tech tree Ideas in Frostpunk 2
| Category | Idea | Effects |
|---|---|---|
| Generator Upgrade I | Generator: Adaptive Pumps | Your Generator can use any fuel |
| Generator Upgrade II | Generator: Adaptive Injectors | Intake Optimisation bonus boosts Heat yield of selected fuel |
| Generator Upgrade III | Generator: Symbiotic Regulator | All fuels yield more Heat Symbiotic Support bonus boosts Housing, Industry, or Food Districts |
| Coal Liquefactors | Coal Liquefactor | Coal Liquefactor converts Coal into Oil |
| Carrion Coal Liquefactor | Carrion Coal Liquefactor converts Coal into Oil Increases Disease slightly Requires fewer materials and offers better conversion rate than Coal Liquefactor | |
| Pressurised Coal Liquefactor | Pressurised Coal Liquefactor converts Coal into Oil Increases Squalor slightly Requires less Workforce than Coal Liquefactor | |
| Settlement Heating | Settlement Furnace | Can upgrade outposts to settlements |
| Melting Deep Deposits | Deep Melting Drill | Deep Melting Drill can access Deep Deposits |
| Housing Insulation | Asbestos Lining | Reduces Heat demand in all Housing Districts |
| Heat Dispatcher | Heat Dispatcher | Heat Dispatcher reduces the Heat demand of its district |
| Actuated Heat Dispatcher | Actuated Heat Dispatcher greatly reduces the Heat demand of its district, but increases Squalor | |
| Food Energy Efficiency | Crop Selection | Reduces Heat demand in all Food Districts |
| Coal Mines | Shaft Coal Mine | Safest but lowest output coal mine |
| Dust Coal Mine | Moderate output coal mine that increases Disease | |
| Blasting Coal Mine | High output coal mine that increases Squalor, and can cause injury and death to workers | |
| Advanced Coal Mines | Advanced Shaft Coal Mine | High output, safe coal mine |
| Advanced Blasting Coal Mine | Highest output coal mine that greatly increases Squalor | |
| Pumpjacks | Pumpjack | Increases Oil output and Squalor |
| Hydraulic Pumpjack | Better Oil output and lower Materials demand than a regular Pumpjack, but increases Disease | |
| Fracturing Pumpjack | Better Oil output and lower Workforce demand than a regular Pumpjack; increases Squalor | |
| Geothermal Plants | Geothermal Plant | Generates Steam with no negative effects |
| Unfiltered Geothermal Plant | Higher Steam output than a regular Geothermal Plant, but increases Disease | |
| Advanced Geothermal Plants | Pumping Geothermal Plant | High output, safe Geothermal Planet |
| Deep Geothermal Plant | Highest output Geothermal Plant that increases Disease | |
| Advanced Pumpjacks | Advanced Pumpjack | High output Pumpjack that increases Squalor |
| Advanced Fracturing Pumpjack | Highest output Pumpjack that greatly increases Squalor |
