After a cold start in sub-zero weather, my friend and I argued about the fastest way to warm up the inside of my car. I would always start the car, drive for few minutes, then turn on the heater fan once the engine temp had more or less peaked. My friend, however, claimed that the fastest way to warm up the cabin would be to turn the fan on immediately after starting the car (and at full blast, ideally), thus blowing in cold air before gradually warming up.
I say my way is faster since you are allowing the radiator coolant and heater core to accumulate heat before displacing it into the air with the fan. My friend says his way is faster since you get the first traces of engine heat right away by turning the fan on immediately after startup.
Is my method faster, or is his, or does it theoretically make no difference between the two. Pros? Cons? Is there anyone who has expertise in the transfer of heat who could settle this for us once and for all? Thank you all.
