The Electric Furnace.

The Electric Furnace is an improved version of the Iron Furnace. The benefits of this device compared to the Iron Furnace are that the Electric Furnace is 12.5% faster and, as the name indicates, uses electricity, in the form of EU. By running on electricity instead of burning items, it is able to shut off immediately upon finishing (thus avoiding wasted energy). You can best take advantage of this by having some form of energy storage between the Electric Furnace and the Generators.

The Electric Furnace uses 384 EU per operation. When connected to a Generator, one piece of coal or charcoal, producing 4,000 EU, will provide 10.4 operations. On the other hand, an Iron Furnace uses 400 EU per operation, and it doesn't stop when there is nothing left to smelt. It can accept a maximum voltage of 32 EU/t (more than that will cause the furnace to explode). Additionally, an Electric Furnace can be powered by alternative sources such as Solar Panels. Its block ID is 250:2.

Storage 416

Each operation costs approximately 307 EU.
Maximum input: 32 EU/t before exploding


The four slots on the right are used to upgrade the machine. The three upgrades that are available are the Overclocker Upgrade, the Transformer Upgrade and the Energy Storage Upgrade. You can stack upgrades, but there is no use having more than 3 transformer upgrades or 13 overclocker upgrades in a furnace.

The following table shows the amount of time it takes to smelt compared to how many overclockers are in the furnace, and how much EU/t the furnace now requires with the added overclockers (note that ingame the values are rounded DOWN to the nearest tick and EU/t respectively):
