Expanding Minecraft Thermally! A server-friendly and content-rich blend of magic and technology!

For nearly a decade, the Thermal Series mods have been a cornerstone of modded gameplay. They've pioneered gameplay innovations and optimizations used in practically every modern mod in existence. The Forge Energy system was built from Redstone Flux, and many common modded features - side reconfiguration, advanced redstone control, blue/orange input coloring - all started with the Thermal Series.

The Thermal Series is a modular series of mods, allowing players, server owners, and modpack creators to easily choose the aspects which they want and those which they do not, allowing it to fit into a variety of gameplay styles and worlds.

As a set, the mods form a cohesive experience which greatly expands the Minecraft universe in a lore-friendly (but admittedly technological) way.

This module contains "Expansion" - the original mod in the series, going all the way back to Minecraft 1.2.5. It contains the "industrial base" of the Series, providing options for energy generation, storage, and resource processing!

The mods are still being updated regularly and the Series is not complete yet! We're working on it and appreciate your patience. Even so, there's a LOT of stuff for both newcomers and veterans. We hope you enjoy the new Thermal Series.

Configuration

  • Client: thermal-client.toml file located in /config
  • Server: thermal-server.toml located in the /saves/WORLD_NAME/serverconfigs folder.

Copying this file to your /defaultsconfig folder will apply those configs to all newly created worlds.

Dedicated servers will have this file in /world/serverconfigs

Frequently Asked Questions

Thermal Expansion server crashes on startup – what to do?

Most common cause: wrong forge version or insufficient RAM. Check the server log (latest.log) for "OutOfMemoryError" or "Mixin" errors. With Mado Hosting: ensure at least 4 GB RAM is allocated and the loader matches the mod version (1.20.1). You can switch loaders with one click in the panel.

Is Thermal Expansion compatible with forge?

Thermal Expansion officially supports forge for Minecraft 1.20.1, 1.19.2, 1.18.2. The Mado dashboard automatically detects incompatible loader combinations.

Server lagging with Thermal Expansion – how to optimize performance?

Recommended RAM: 6 GB (per 5 players). Use /spark profiler to check if Thermal Expansion consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge. With Mado Hosting, your server runs on NVMe SSDs with dedicated CPU cores for minimal latency.
