Mekanism: Heated
New chemistry-oriented machines based on Mekanism's temperature and heat system.
Quick answer
Which Mekanism: Heated release should I use?
Mekanism: Heated mekanismheated-1.0.2.jar targets 1.21 with NeoForge. The project page does not say whether this file belongs on the client, dedicated server, or both. All 1 required mods have matching files.
Where it goes
Is Mekanism: Heated required on the client, server, or both?
The project page does not say whether this file belongs on the client, dedicated server, or both.
The source does not explicitly classify this release as client-only or server-only.
What else does Mekanism: Heated mekanismheated-1.0.2.jar need?
mekanismheated-1.0.2.jar. Change the file and its required mods may change too.
Install Mekanism first. We found matching files for this game-version and loader setup. 23 come through another mod in the chain.
23 extra mods were pulled in by other dependencies. Indented rows show who needs each one. We only count dependency files that match this setup. A file for another loader does not fill the gap.
Before you install it

About this project
What does Mekanism: Heated add?
Overview
Mekanism: Heated is an addon of Mekanism that uses heat and temperature to control machines, rather than energy. It also adds more chemical instances and their reactions, since they usually happen under a certain temperature.
JEI and Jade are supported.
The mod is still in its early development. Expect more updates later.
New Machines
Heat Smelter
A smelter, but not only a smelter. It supports 4 recipe types:
- Smelting. Starts working above 300K and linearly scales to full speed at 1000K, where full speed is 100 ticks per item (double speed of vanilla furnace).
- Melting. Every supported item has a different temperature when they start melting, e.g. copper ingot at 1084℃ and iron ingot at 1535℃, to match physical reality. Note that cobblestone can be melted into lava at 1500K.
- Temperature-controlled smelting. Similar to normal smelting, but happens only at a certain temperature.
- Alloying. Two melted metals that can alloy will automatically alloy inside the machine.

This is a working heat smelter with liquids. The block beside it is a creative heat source, obtainable only in creative mod and can set temperature freely.
They can form into a larger smelter, from 2x2x2 to 6x6x6, similar to jumbo furnaces:

Condenser
Condenses molten metal to ingots. Also allows inputting another item to combine them, e.g. pouring molten diamond onto infused alloy will give you reinforced alloy.
Fractionation Tower
Similar to evaporation tower, but separated by distillation trays. Every compartment formed by the trays will be an output tank, with the exception that the lowest compartment will be the input tank. Works only under a certain temperature range.
Passively generates liquid nitrogen, liquid oxygen and liquid air remnant under 85K (i.e. fractionating air).

This is a fractionation tower with a creative heat source attached to it.
NOTE: I didn't change the texture for now, it looks the same as evaporation tower. This is on TODO list.
Cooler
Like resistive heater, but uses energy to cool things down.
Shaker
A normal Mekanism-like machine that produces chemical instances (Fe2O3, SnO2, CuO etc) from cobblestone, gravel, sand or clay. These are then fed into other machines to extract ingots. In Create you can get iron and gold out of cobblestone, so why in Mekanism you can't?
Reaction Chamber
Not pressurized reaction chamber; this one is much more flexible. Just input any chemicals and fluids, or even plus an item, then it will react to its full, while recipes are controlled by temperature. It holds at most 16 types of chemicals and 16 types of fluids. It can become chaotic!

This is a full reaction chamber. The reaction going on is C + H2O = CO + H2.
Fused pipes
5-in-1 pipe. Transmits energy, chemical, fluid, heat and items. Note that these pipes have buffer, like Mekanism pipes do. When you have Jade and look at it, you'll see the pipe network's contents.
In the previous image, the pipe between the water tank and the reaction chamber is a fused pipe.
