The Last Caretaker Bring Back the Heat Quest: Heat Up North Bastion

Short answer: Bring Back the Heat is the first North Bastion story quest in Update 6. When you come through the Transfer Gate into the cold, find the heating system and use the Boiler to send steam to a heater: the Boiler makes steam and a connected heater turns it into heat. Unlock both in the skill tree first. The story then moves on to Reach North Bastion, Find the Laboratory and I Know This Place.

The cold and the heating modules are official (A); what the quest asks, how steam reaches a heater and the quests that follow are cross-checked in streams, a walkthrough and Steam threads (B). Single-source numbers are marked C.

What Bring Back the Heat Asks

What is the Bring Back the Heat quest?

Bring Back the Heat is the first quest of the North Bastion story in Update 6. It starts when you come through the Transfer Gate into the cold: look for the heating system, then get the Boiler sending steam into a heater so the heater gives off heat.

Update 6, The Jump, came out on October 19, 2026. In deep cold the Caretaker moves more slowly and starts losing health, and a temperature readout appears on the HUD once conditions turn dangerous. North Bastion, the new frozen mountain region, is where the cold matters most.

How to Finish It

How do you supply steam to a heater?

A Boiler produces steam, and heaters connected to it turn that steam into heat.

The Boiler and the heaters are skill-tree unlocks, so unlock them before you look for them in the build menu. One beta player at first missed that the heating modules had been added to the skills.

To survive the cold you can build small, medium and large heaters, a Boiler and the Methane Extractor, and use single-use methane canisters. Each heater type has its own output, reach and efficiency, and a warmed area no longer cools back down.

One beta stream’s tooltip shows the FLO BH-60 Boiler taking Methane 10,000 L/h and Fresh Water 10,000 L/h and making Steam 30.0 kW; we have not seen a second source for these numbers.

Where do you connect the heater?

In North Bastion the steam pipes on the walls have their connection points in groups of three, and players run hoses from them to their heaters.

A player found that too many heaters on one Boiler leave some of them without enough steam pressure, that a room heater needs less steam than an area heater, and that a second Boiler gave enough pressure to heat the bunker harbor.
