Warm up?

I said yes, but didn't read carefully. I start it and go, but drive respectfully until the car is fully warm. Then if I want to rev her higher I will. Best not to warm the car at idle, engine warm everything else cold and you will harm the other components if you drive aggressively immediately.

Heat DOES come from the engine...
Coolant (heated by the engine) circulates through the heater core -- which is like a radiator and then a fan blows air past this providing heat. There is a direct correlation between the water temp (coolant) of the engine and the maximum amount of heat that you can achieve. Cars warm up faster if you drive them vs idling. Or- did you mean that most people think car heaters are like those in old VW beetles/vans-- air directly from the engine compartment is used to provide heat...

Heater cores aren't like radiators, they are radiators.
