    those PTC heater elements might be ok for a cool morning in Florida but at 10 below you might as well be smoking a cigarette.

    Ok I know you guys are talking about some very extreme low temps however I have a question about the function of the heat and not so extreme temps. Is my heat going to work fine this winter when temps hit around 15- 20f? I like it warm, in the summer I usually set my ac to 76- 80f, my house is also around 80f all year. This will be my first winter with a Prius and I am going to be very very upset if my heat doesn’t work well. If I travel to the north (Maine) and it gets even colder will I have heat? I can almost (at least most days) get by with no ac but I refuse to be cold.

    That just barely qualifies as "real" winter. It's no big deal for a Prius. Any warmer and you'd be able to cook stuff with the heater.

    Basically, there is no issue whatsoever until the temperature drops to near 0 F.

    So when I drive up to Maine for Christmas I am going to have problems during the drive or only when I first start the car?

    I can handle a little warm up lag, but not having adequate heat wile driving is going to have me po’d

    It all depends on two things.

    1 What car are you coming from? Another small 4 cyl car or a big car with V8 and tons of extra heat.

    2 How fast are you driving during warm up. Even at 15 deg F the Prius without mods will not warm up driving 25 to 35 mph with lots of stops at red lights. On a highway at 55 or faster it will warm up fine.

    Around Boston area I find the car cold compared to most cars I've owned, but not compared to other 4 or less cylinder cars.
    And I have added insulation and cold front etc that help me keep warm now, after freezing my first winter with the car.

    I am now comfortable at any temps down to about -10 F at least.

    I had a Mini Cooper S, but that car would warm up before I got even half a block from home. (1.6l supercharged 4 cylinder)

    I am more worried about being stuck in traffic. I hope the car can stay warm wile I drive on the highway at 50- 60 mph.

    If I have to modify this car just to stay warm, I am going to be questioning owning the car. Seriously if I get stuck in traffic or a bridge opening were I will be stopped for 15 or more minutes and I lose heat. I may consider going back to a Mini and I will not lease it at that that point. Im sure the trade in on a 2006 Prius with 6,000 miles would pay for a decently equipped Mini.

    What effect will being parked in the street have on the car warming up / staying warm. I don't have a garage and my parking garage at work isn't heated. The worst we usually get cold-wise is a stretch of sub-10F temps.

    I recommend you look into a "cold front", or some way to block the air inlets in the front. This is safe, as there is a gap between the front of the car and the radiator. The rad. fan can still draw air from this gap.

    On any car I've owned, this makes a big difference. Car warms up faster, cools off slower, says warm longer.

    As far as parking on the street, remember wind chill has only one effect on things not alive - they cool off faster, but they only get to the actual temp., not lower, that is, not the windchill temp. Parking on the street will mean the car will get to ambient, which will be lower than if it was in a garage (even an unheated garage). It will take longer to warm up the interior. In NJ you don't really get the cold temps. I've been talking of, so you shouldn't have a real problem with warmup. I'd recommend blocking the front vents though, just to save gas. Using the pipe insulation makes it easy and inexpensive.
