How to Install and Use Thermal Foundation in Minecraft

What Thermal Foundation Adds

Redstone contraptions are useful in vanilla Minecraft, but the toolset can feel cramped once you want serious machinery, extra materials, or powered gadgets. Thermal Foundation expands that space with new resources, energy-related items, tools, mobs, and shared components used by other Thermal mods.

Created by the CoFH Team, Thermal Foundation has been a major Forge mod since 2014 and has earned tens of millions of downloads on CurseForge. Its name is literal: it provides the foundation that other Thermal mods build on. Players often use it for technical builds, resource processing setups, and modded progression that goes beyond standard redstone.

The mod supports Forge versions from 1.7.10 through 1.18.2, depending on the release you choose. For best results, match the mod version to your exact Minecraft and Forge version before installing anything. Minecraft is picky about versions because apparently one number being off is a personal insult.

Requirements

Thermal Foundation needs CoFH Core to run. Install both Thermal Foundation and CoFH Core on your client and on the server. If one side is missing a file or using a mismatched version, players may fail to join or the game may crash during startup.

Installing on Your Client

1. Open the Thermal Foundation and CoFH Core download pages, then go to the Files section.

1. Choose the file that matches your Minecraft version and Forge build.

1. Download both mod files and keep them somewhere easy to find.

1. Move the downloaded `.jar` files into your launcher's `mods` folder. The exact folder location depends on the launcher you use.

1. Start Minecraft with the matching Forge profile and confirm both mods load correctly.

Installing on a Server

Before starting, make sure you have both required `.jar` files ready.

1. Open your server control panel and access the server files.

1. Go into the `mods` directory.

1. Upload Thermal Foundation and CoFH Core, then wait for the upload to finish completely.

1. Return to the main server controls and restart the server so the mods can load.

First Steps in Game

A new world with Thermal Foundation installed may look normal at first. Most of the differences appear once you explore, craft, mine, or browse the creative inventory. The exact item list depends on the mod version, so two installations on different Minecraft versions may not have identical blocks or recipes.

If you are playing survival, installing a recipe viewer such as Just Enough Items is strongly recommended. Thermal Foundation adds enough materials and components that checking recipes manually can become tedious fast.

Useful Tools

Thermal Foundation includes several tools that help with mining, storage, security, and utility work.

The remote detonator gives TNT a safer trigger method. Instead of standing next to an explosive block like a very confident skeleton, you can bind the detonator to TNT and set it off from a distance. Right-click the TNT, press `V`, then right-click again to trigger it.

The signalum security lock is useful on shared servers. Hold the lock and right-click a compatible block to restrict access to yourself. It is a small feature, but on larger modded servers, protecting storage or important blocks can prevent a lot of arguments.

The satchel works as extra storage for collected items. Hold it and press `V` to configure what it accepts, then pick up matching drops to move them into the satchel automatically. This is especially helpful while mining, farming, or clearing large areas where inventory space disappears quickly.

New Resources and Materials

Thermal Foundation adds a large collection of blocks, ores, ingots, gears, dusts, and crafting components. Many of these resources generate naturally in the world, while others are created through crafting or processing.

These materials are important because they feed into the rest of the Thermal ecosystem. Even if the base mod does not add every machine by itself, its metals and components are often required for tools, gadgets, equipment, and addon content. Creative mode is the easiest way to inspect the full item set for your installed version.

Tinker's Workbench and Energy Items

Energy is one of the main themes of the Thermal series. Thermal Foundation introduces fuels and energy-related components, including items connected to Redstone Flux. The Tinker's Workbench is used to manage certain powered items and components, though the base mod becomes much more interesting when paired with other Thermal addons.

To craft a Redstone Reception Coil, gather:

• 2 Redstone
• 1 Gold Ingot

After making the coil, craft the Tinker's Workbench with:

• 3 Iron Ingots
• 2 Glass Blocks
• 1 Crafting Table
• 2 Wood Planks
• 1 Redstone Reception Coil

Added Hostile Mobs

Thermal Foundation adds three hostile mobs: Blizz, Blitz, and Basalz. They behave somewhat like elemental relatives of blazes, but each one appears in different areas.

• Blizz spawn in cold biomes.
• Blitz spawn in deserts and savannas.
• Basalz spawn in mountains and hill biomes.

These mobs are rarer than many standard hostile enemies and may spawn in small groups of one to four. They can be dangerous, so pay attention when exploring their biomes, especially early in a world.

Configuration Options

Server configuration is stored in `thermal-server.toml` inside the world's `serverconfig` directory. This file includes options for behavior such as energy retention and item usage.

Most servers can leave the default settings alone. If you add more Thermal mods, it is worth reviewing the config so the full setup behaves the way you want.

Thermal Addons

Thermal Foundation is designed to support related mods. Common addons include:

• Thermal Cultivation: adds watering cans and farming tools.
• Thermal Dynamics: adds blocks for transporting items, fluids, and energy.
• Thermal Expansion: adds machines, processing systems, and progression tools.
• Thermal Innovation: adds specialized tools and equipment.
• Thermal Integration: improves compatibility with recipes, materials, and enchantments.
• Thermal Locomotion: adds rails and carts for transportation systems.

Final Notes

Thermal Foundation is best viewed as the starting layer for a larger technical Minecraft setup. On its own, it adds resources, tools, utility blocks, hostile mobs, and energy components. With addons, it becomes the backbone for machines, automation, transport, and more advanced Forge gameplay.
