Frostpunk 2 District Heat Management Guide
Heat management is Frostpunk 2's central survival mechanic. After the version 1.5 update, heat operates at the district level: each zone has independent heat demand that you satisfy through generator output and Heating Hub coverage. Under-heated districts stop functioning, cascading into food shortages, material deficits, and population loss. This guide teaches district heat allocation, adjacency optimization, hub placement, and fuel efficiency for campaign and Utopia Builder.
This guide specifically addresses version 1.5 district-level heat mechanics. For overlay reading techniques, see the economy overlays guide. For numerical adjacency values, see the adjacency and heat bonuses guide.
District-Level Heat Allocation
Each district displays heat demand and current allocation in the district management interface and heat overlay. Generator output distributes across districts based on your allocation settings. Total allocation cannot exceed generator capacity without overdrive modes that increase fuel consumption and generator stress.
Monitor heat daily during expansion phases. Each new district adds aggregate demand that may require generator upgrade research, additional extraction for fuel supply, or Heating Hub construction for remote zones. The heat overlay with key 4 shows citywide demand versus output at a glance, highlighting districts at risk before cold snaps arrive.
Adjacency-Based Heat Reduction
Positive adjacency effects reduce district heat demand by 20 points per qualifying bonus. Housing Districts benefit from generator adjacency, crevasse shelter, and same-type Housing clustering. Each bonus stacks independently, potentially reducing a Housing District's heat demand to zero before Heating Hub supplementation.
Plan adjacency during frostbreaking by selecting tile clusters aligned with crevasse edges and generator proximity. Press 8 for proximity overlay during construction to preview accumulated bonuses. Industrial and Extraction districts cannot achieve the same heat reductions as Housing but should still avoid placement that increases demand unnecessarily through wind exposure on unsheltered tiles.
Heating Hub Networks
Heating Hubs extend heat coverage to districts beyond generator range. Each hub covers adjacent districts within its radius, reducing net heat demand for covered zones. In sprawling Utopia Builder cities, chains of Heating Hubs create heat corridors enabling Housing and Food Districts far from the generator.
Overbuilding Heating Hubs wastes materials and workforce without proportional benefit. Model expected heat demand with the Heat and District Calculator before placement. Place hubs at network junctions where multiple districts benefit simultaneously rather than covering single isolated districts individually.
Zero-Heat Housing Layouts
Advanced players design Housing Districts with zero net heat demand by combining generator adjacency or crevasse shelter with Housing cluster bonuses. Zero-heat housing frees generator output for Industrial and Extraction districts during whiteouts when fuel reserves tighten and every heat unit matters.
Zero-heat layouts require deliberate frostbreaking planning rather than reactive construction. Identify crevasse-adjacent tile clusters near the generator during initial expansion. Verify accumulated bonuses with proximity overlay before spending 200 workforce per Housing District. These layouts appear in our adjacency guide and work especially well on Hanging Rock and Fractured Gorge maps.
Fuel Supply and Generator Management
Heat allocation means nothing without fuel supply. Coal Mines and Oil Derricks in Extraction districts feed generator consumption. Fuel Stockpile Hubs buffer reserves for whiteout periods when extraction slows. Monitor fuel levels alongside heat allocation using overlay key 4.
Generator research through the Heating branch unlocks efficiency upgrades and alternative fuel modes. Transition from coal to oil in Chapter 1 changes consumption calculations. Deep Geothermal Plants on suitable tiles provide passive heat generation reducing overall generator burden. The hub buildings guide covers Fuel Stockpile Hub construction timing.
Whiteout Heat Priority Protocol
During whiteouts, apply strict heat priority: Housing first, Food second, Extraction third, Industrial fourth, Logistics last. Pause and verify allocation across all settlements including Frostland colonies. Reduce Industrial allocation before Housing if fuel runs short. Accept temporary material production loss rather than population decline.
Pre-whiteout preparation from our whiteout preparation guide ensures adequate fuel stockpile for peak demand. Post-whiteout, rebuild reserves before resuming expansion. Iceblood faction bonuses reduce fuel consumption during whiteouts, making them particularly strong on heat-intensive maps ranked in our map tier list.

Frequently Asked Questions
What changed in version 1.5 heat management?
Version 1.5 shifted heat allocation from city-wide distribution to per-district management. Each district has individual heat demand and allocation levels that you adjust independently rather than managing a single city heat pool.
How do I identify under-heated districts?
Press 4 to toggle the heat and fuels economy overlay. Districts shown in warning colors receive insufficient heat and will stop functioning if temperatures drop further or if allocation remains inadequate during whiteouts.
What is zero-heat housing?
Zero-heat housing achieves districts with zero net heat demand by stacking adjacency bonuses from generator proximity, crevasse shelter, and Housing cluster effects, optionally supplemented by Heating Hub coverage. This frees generator output for production districts.
Should Industrial districts receive full heat during whiteouts?
Industrial districts can tolerate brief under-heating if Housing and Food districts maintain full allocation. Prioritize residential and agricultural heat during fuel shortages, accepting temporary material production reduction rather than population loss or food collapse.
