The Induction Furnace is an advanced version of the Electro Furnace. It has the ability to process 2 stacks of items simultaneously. Doing so will also save 50% of the energy that would have been used had every stack been smelted by itself.
Another feature of the Induction Furnace is its ability to build up heat. At higher heat levels, the Furnace both smelts faster, and uses less energy per smelting action.
Please note the above GUI is not correct. The smeltable items are put into the two top slots, and then the Furnace is supplied with EU. Note that the furnace can accept both Low Voltage and Medium Voltage (up to 128 EU/p). The processed items appear in the two rightmost slots.
During its operation, the Furnace will build up heat, up to 100%. When idle, the heat will slowly dissipate back to 0%. It is possible build up and maintain the heat by providing a redstone signal to the Furnace. In that case, the Furnace will constantly consume 1 EU/t when idle to maintain the heat. Smelting while applying a redstone signal does not make the Induction Furnace warm up faster.
It takes 10,000 ticks for the furnace to build up from 0% heat to 100% (8 minutes and 20 seconds) at a cost of 10,000 EU, not including EU spent smelting during the warm-up time. This implies that there's a minimum amount of smelting before which it's inefficient to use the Induction Furnace. Additionally, the furnace loses heat four times faster than it builds up (2 minutes and 5 seconds).

†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.
