The Electric Furnace is an improved and more costly 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. By running on electricity instead of burning items, it is able to shut off immediately upon finishing (and thus avoid wasting energy). You can best take advantage of this by having some form of energy storage between the Electro Furnace and the generator(s).
The Electric Furnace uses approximately 390 EU per operation. When connected to a Generator, one piece of (char)coal will provide 10 operations. An Iron Furnace, in comparison, uses 400 EUs per operation (Coal has an EU yield of 4000 in a Generator and provides 10 operations in an Iron Furnace) and it doesn't stop when there is nothing left to smelt. Additionally, an Electric Furnace can be powered by alternative sources such as Solar Panels , BatBox , MFE or MFSU . NOTE: To use the Electric Furnace with a MFE or MFSU , you MUST use a transformer or you will make the Electric Furnace EXPLODE.
See: Crafting Guide
Simply add something to smelt in the top slot and supply the Electric Furnace with EU.
- The lower slot is used to provide power from a RE Battery or other energy storage item if a direct Cable connection is not available.
- To carry items to the furnace using BuildCraft pipes, you must have the pipe feeding into the top of the furnace.

†Other Wood Items = Any block with its material set to "Wood" (includes blocks added by other mods if material defined properly). Includes all other items that can be burned in a regular Furnace, see
Smelting for a complete list.
‡Assuming the smelting of 2 items simultaneously, divide by 2 if you are only smelting one item. For values < 2 keep in mind that you will actually have 2 partially finished units.
††All lava containers (e.g. Lava Cells, Lava Cans from Forestry) can be used in Iron Furnaces and Generators from 1.113 onwards.
‡‡All lava containers are worth 10% of their value (2000) inside Iron Furnaces and Generators.
†††Considering as using a Geothermal Generator. Divide by 10 if using a normal Generator instead.

The Electric Furnace can accept overclocker upgrades, meaning that it can potentially smelt items faster than its advanced counterpart, the Induction Furnace. While an Electric Furnace with a large number of overclockers can smelt items much faster (about 20 items per second max) without drawing energy when inactive, it can only process one stack at time, making it horrendously energy-inefficient in comparison.
Now, we got Iron Furnaces. And we got Redstone dust that for no apparent reason powers circuits indefinitely.
What do you think we would make of this? Cake? No!
We created a completely new Furnace for you, THE ELECTRIC FURNACE.
As everyone knows, burning things to smelt stuff is reaaaaally old-school. It's like using a Commodore 64. And who's using one right now? Noone, right!
An electrical powered device has 3 important advantages.
First of all, without the wasteful burning of random stuff, much less energy is wasted during operation, meaning would could improve the smelting time of our all-beloved Iron Furnace by further 12.5%! Now, that alone would be a reason to instantly upgrade to Electric Furnaces, wouldn't it?
BUT IT COMES EVEN BETTER!
Instead of causing massive pollution and shamefully wasting ressources, Electric Furnaces are powered by, duh, ELECTRIC ENERGY! This energy is brought to you in form of ourueber-l33t T500-Rechargeable Energy Storation Unit. Or, for short: RE Battery. These little thingys can store quite high loads of energy and will power Electric Furnaces for a long, long time.
But what happens if you just want to smelt 5 iron ore, wouldn't such an ueber-powerful battery be a waste? FRIKKIN NO! Because the 3rd advantage of an Electric Furnace is, it will not waste any energy if it isn't currently smelting something. You can just charge it up with a battery and then smelt what you want, whenever you want.
Deal? Deal! HAYO!
