Morphology
The meaning is directly built from 'electric' (relating to electrical power) modifying 'furnace' (an enclosed heating device), so it refers straightforwardly to a furnace powered by electricity. This is a regular compositional noun phrase with no idiomatic shift, and the same logic exists in many languages, so a B1 learner who knows the constituents will understand it.
Etymology
Electric furnace is named for how it makes heat: electric means 'made by electricity' and furnace means 'a hot oven', so electricity heats the inside instead of burning fuel. That's why it means 'a furnace where heat is made by electricity rather than by burning fuel'.
