Hearth
 |
The Hearth is a functional block that heats up or cools down nearby blocks. It is the most important block in base-building and long-term temperature management. |
When fueled, the hearth is capable of applying a cooling effect, warming effect, or both.
When powered with redstone from the sides, the hearth will emit steam and grant players the Chill effect, consuming cold fuel in the process.
When powered with redstone from the bottom or back, it will emit smoke and grant players the Warmth effect, which consumes hot fuel.
After being placed, the hearth takes up to one minute to reach full effectiveness. This is represented by gradually increasing levels of the Warmth or Chill effect, starting at level I (1) and building to level X (10) over the duration.
The hearth's area-of-effect spreads outward from the block's location, passing through all non-solid surfaces and filling the room it occupies.
Note: A solid surface is defined as any face of a block's hitbox that covers the entire 16x16-pixel area. For example, oak planks are a solid surface on all sides, but oak stairs are only solid on some sides, but not others. Any block that the hearth spreads to must have a solid roof (solid, as defined above) directly overhead.
The hearth can affect up to a total volume of 12,000 blocks, with a maximum range of 96 blocks. Note that in a wide-open area, the hearth may not be able to extend to its full 96-block radius in every direction due to the 12,000-block limit.
The hearth is only operational in a closed room, which is defined as any area that has a roof. It will not regulate the temperature of areas that have direct sky access.

The hearth has two fuel pools: one for hot fuel, which warms up players in cold environments; and one for cold fuel, which cools down players in hot environments.

Hot:
- Coal (3.7%)
- Charcoal (3.7%)
- Burnable Planks (3.7%)
- Burnable Log (33%)
- Coal Block (33%)
- Magma Block (33%)
- Lava (100%)

- Snowball (1%)
- Clay Ball (3.7%)
- Snow Block (10%)
- Ice (25%)
- Clay Block (33%)
- Powder Snow (10%)
- Packed Ice (100%)
Liquid lava and water can also be piped into the side of the block (except the front or top) for automation. Cold Sweat does not provide pipe blocks, but pipes from most automation mods should work, such as BuildCraft, Create, or Integrated Dynamics.
Water and Lava can be drained from the Hearth on certain sides. Only lava can be drained from the bottom, and only water can be drained from the sides (except the front or top). Fuel can be inserted on any valid side.
- Taking advantage of the thermolith's ability to detect the local temperature, the hearth is able to be controlled automatically via redstone signal.
- Multiple hearths' areas can overlap, but will not stack in effectiveness. It is most economical to
