Question:
So my dad and I were discussing whether putting the car heater on full blast when we first get into a freezing car will make the car heat up faster, or whether it just takes the same amount of time to just keep it on low until the engine is revved up. It's one of those things I've always wanted to know...
Answers:
does it take more gas to use the cruise control, or less?
I don't know for sure, but I'm a full blast heat in a freezing car person. I am sure it helps it warm up faster. I have no proof, but I like to do it.What happens when you put regular gas in a diesel fueled car?
Your car won't get warm on the inside until your engine is warm. Having it on high right away will just circulate cool air. Once you feel it warm up, you can turn the fan to high. Your car heats the inside by blowing the heat byproduct from the running engine into your car.Who invented traffic "witches hats"?
Both KJ and Buffy are correct. Your car won't be warm until the engine is warm; but I wouldn't recommend leaving your car running unattended. Be safe this winter.driver side wing mirror 1999 astra.?
Let the car warm up first then blast the heater. Depending on what year, make and model the anti freeze has to be warm enough to pass through the heater core to radiate heat into the passenger compartment through the air vents. So bottom line blast heater last!won't make the car warm up faster, and driving it rather than idling will warm it up faster

Well its kinda hard to say...by turning the heat up all the way, you are activating the fan blower motor. This puts strain on the electrical system and causes the alternator add a bit more friction as it is charging the battery. This extra friction could be just enough to allow the engine to warm up just a tiny bit faster.Why do you park your car so close to mine...?
The other way you look at it is that since you have the blower going full blast, cold air is being pushed through your heater core (mini radiator in your HVAC system). Since this air is likely cooler than the fluid (coolant) running through the core you may be increasing the warm up time on your engine.

You could really argue it either way, I am leaning toward letting your car warm about half way up before turning the heat on (a nice compromise), but I would like to see anyone try to prove which is actually better.

it does take a while for the heater to warm as the motor warms up but i think we all put it on high i do just be glad u have heat lolI agree that KJ and Buffy are right. And you can figure it,s going to take a good 5 to 8 minutes before you useful heat as it takes that long for an engine to develop any heat.

You are all wrong: U all never even thought about the oil on a cold and frezzing morning have you. all oil is in the pan and not in the engine/that is why we have a oil pump to transfer oil up and into the engine/ lot of people hear saying to revvvv engine to get the heat going faster is wrong. let it idle it self after starting until cold light goes out or until temp gauge reaches 120 and turn on heat and drive car after that is the best way leave heater off until then will do no good/ except blow cold air.More Questions & Answers ...
