how my $20 space heater has hot air after 5 seconds while my car takes 3/4 minutes

Question

Edit: meant to put 3-4 minutes not 3/4

Answer 1

Your car’s heater is getting free heat from the engine, but that only works once the engine gets hot, which takes a few minutes. The space heater is taking energy from the power mains, which is faster to heat up, but you have to pay for it.
