This is completely different from a glowplug used to heat up the coolant, which might stay on for a couple of minutes.

The intake ones are yet a different system. I remember them in very ancient direct injection Japanese systems. They're not as efficient, but a direct injection engine can start unaided at much lower temperatures. I can't recall any modern engine with them.
Multi KW high voltage coolant heaters, two plain block heaters, glow plugs, intake heaters. I have them all.
OEM configuration had glow plugs and a single block heater. Insufficient for my hatred of winter.
