The Electric Furnace is an Industrial Craft 2 machine. Unlike the normal vanilla Furnace or the Iron Furnace, the Electric Furnace requires EU to run. The Electric Furnace only draws power when it needs to complete an operation, making it far more efficient than either of the normal furnaces.
The Electric Furnace is a Low Voltage machine and can only accept 32 EU/t. If one wishes to connect the Electric Furnace to the MFE, MFSU, or any of the Medium and High Voltage generators, a Transformer Upgrade is required.
The Electric Furnace's GUI resembles the vanilla Furnace's GUI. Power sources, such as the RE-Battery, can be placed in the bottom slot, while the items to be processed are placed in the top slot. Without Overclocker Upgrades, the Electric Furnace takes 390 EU to process one item.
Like most of Industrial Craft 2's machines, four upgrade slots are available on the right side of the GUI. The Overclocker Upgrade can speed up the Electric Furnace's operation at the cost of drawing more power, the Transformer Upgrade allows the use of Medium and High Voltage energy sources, such as the MFE, the Medium Voltage Solar Array, or the Energy Crystal, and the Energy Storage Upgrade allows the Electric Furnace to buffer more EU in its internal memory storage, allowing it to run longer without being powered.
