How to Store Solar Heat Using Salt and Heat Batteries

The Solar Heat Chain allows you to capture energy from the sun and store it as thermal energy to run your boilers.

Gathering Salt and Melting It

To begin heating salt, you need raw salt resources and an open workspace:

1. Search underground in hot biomes, such as deserts and savannas, to mine natural salt blocks, or craft salt yourself.

2. Place a Solar Heater outside in an area with an unobstructed view of the sky.

3. Feed your mined or crafted salt into the Solar Heater during daylight hours. The heater uses direct sunlight to melt the solid salt into hot liquid salt.

Transferring Heat to Your Boilers

Once you have liquid salt, you need to store and route the heat to your machinery:

1. Pipe the hot liquid salt from the Solar Heater directly into a Heat Battery.

2. Position the Heat Battery adjacent to your boiler setup.

3. The Heat Battery will discharge its stored heat directly into the boiler to heat it up, allowing you to generate steam without continuously burning solid fuel.

4. Check your custom advancement tab to track your progress through the solar heating machine sequence.
