About this Mod

Heater

Heater offers a new way to power Furnaces, Blast Furnaces, Smokers, and every other machine that consumes fuel to do some work, even from other mods.

Heater Showcase

(Credits to StarOcean for the fantastic textures they created!)

It does this with only three new blocks: the eponymous Heater, the Heat Pipe, and the Thermostat, each with weathered and waxed variants.

Heater

Heater Block

As this mod's namesake block, the Heater is at the core of this mod and is crafted as follows:

At first glance, it looks like a normal furnace-like block—even its screen is very similar to one:

However, instead of processing items within itself (hence the lack of slots other than the fuel one), it propagates the heat produced by the fuel it burns to nearby blocks, powering every furnace-like block it finds.

Heat Pipe

Heat Pipe Block

As shown in the showcase above, the Heat Pipe is, unexpectedly, a pipe through which any Heater can propagate the heat it produces, functionally extending that Heater's reach.

It's crafted very easily as follows:

It's also very efficient because it doesn't have an entity, which means you can place many of these pipes without affecting performance.

Thermostat

Thermostat Block

Last but not least, the Thermostat offers a degree of control over how heat propagates between Heaters and furnaces, and across Heat Pipes.

It's crafted as follows:

Thermostat Recipe

Thermostat Recipe

By default, a Thermostat lets heat propagate through itself only if it is redstone-powered, and only in the direction it's facing (the full coppery side).

However, right-clicking a Thermostat opens the following screen:

And clicking the central slot with a fuel item sets the Thermostat to filtering mode for that fuel. In this mode, when unpowered, this block only propagates heat generated by the filtering fuel, while when powered, it converts the heat it propagates as if it had been generated by the filtering fuel.

Finally, the Thermostat is the only block that can propagate heat back into a Heater, acting like a heat repeater.

Interoperability

This mod's interoperability, that is, its ability to work with other mods, depends entirely on Burning, so look there for more details and troubleshooting.

Frequently Asked Questions

Heater server crashes on startup – what to do?

Most common cause: wrong fabric version or insufficient RAM. Check the server log (latest.log) for "OutOfMemoryError" or "Mixin" errors. With Mado Hosting: ensure at least 3 GB RAM is allocated and the loader matches the mod version (26.3). You can switch loaders with one click in the panel.

Is Heater compatible with fabric?

Heater officially supports fabric for Minecraft 26.3, 26.2, 26.1.2. The Mado dashboard automatically detects incompatible loader combinations.

Server lagging with Heater – how to optimize performance?

Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if Heater 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.
