Electric furnace
Overview
The electric furnace is one of the furnace tiers shown in the production comparison table alongside the stone furnace and steel furnace. In that comparison, it matches the steel furnace’s listed processing rate for every resource shown, while the stone furnace works at half that speed for most of the same materials.
In the table, coal consumption is listed for the stone furnace and steel furnace at 0.0225/sec, but no coal consumption value is shown for the electric furnace. For the materials that are compared directly, the electric furnace processes them at the following rates:
This makes the electric furnace a direct throughput upgrade over the stone furnace for all listed materials, and it performs identically to the steel furnace in the data shown. The comparison also makes clear that the furnace line is not uniform across all inputs: lithium plate and steel plate are smelted more slowly than iron, copper, and stone brick, so the electric furnace’s value is strongest where higher furnace throughput matters most.
Because the available source material is a throughput table, no placement, power, recipe, or technology details are given here. The key practical takeaway is simply that the electric furnace sits at the top of the compared furnace entries for raw processing speed, with the same listed output rates as the steel furnace and higher rates than the stone furnace.
