Depends on what heater you're talking about.
The regular heater uses excess heat from the engine, heat that would otherwise had been removed by the radiator. And then some electricity to power a fan to spread that heat through the car.
But some cars (particularly diesels) do have extra heaters, that do run on fuel. And some electricity to pump the coolant around, to power a fan, fuel pump and ignition system for the heater.
Not in most autos. The heater core is like a small radiator, hot coolant from the engine flows through it, then the heater fan blows warm air into the interior of the car. Some military vehicles did have gas heaters. The gas heaters were used warm the engine oil pan in sub zero climates so the enging could be started after about ten minutes. Oil in extreme cold gets thick.
