Survival Log Cold Wave Guide: Heater, Fuel & Staying Warm
Quick answer
After a cold-wave warning, craft the Heater from Sheet Metal and Wire, stage fuel, finish essential outdoor work, and protect food and power systems before temperatures fall.
Quick Answer
v1.0.14911 adds a fuel-burning Heater. After a cold-wave warning, a new event reminds you to prepare heating. The confirmed recipe uses Sheet Metal and Wire.
Cold-Wave Preparation Checklist
- Read the warning and pause lower-priority projects.
- Confirm the Heater recipe is available in the current build.
- Reserve Sheet Metal and Wire before spending them elsewhere.
- Craft and place the Heater where characters can reach it.
- Stage fuel and verify the Heater can operate.
- Repair doors and windows and finish urgent exploration.
- Protect refrigeration and other critical power loads.
- Keep ready food, medicine, and rest available indoors.
The official note does not publish a universal temperature, fuel-per-hour rate, or safe room radius. Use the current Heater interface and event text for those patch-sensitive values.
Heater vs Electrical Power
The Heater is described as fuel-burning, while the home also uses generators, solar panels, batteries, refrigerators, and other electrical equipment. Treat heat and electricity as connected logistics problems even if they consume different resources: a cold wave can stress the same stockpile that powers food preservation and indoor work.
Do not spend every metal component on heating while leaving a broken door or failed refrigerator. The Power guide and Food Spoilage guide cover those dependencies.
During the Cold Wave
- keep the Heater fueled and reachable;
- watch current character-state warnings rather than assuming warmth is global;
- avoid nonessential exploration when the event raises risk;
- check refrigerated food after any outage;
- keep repair materials ready if the cold wave overlaps a horde.
