Need a block heater... what works best?

[Daox]

I just got a heater for my other car. I wanted something that would warm up the car ASAP so I didn't have to wait and could use it on a whim or unplanned trip. I don't leave it plugged in all the time because they're huge energy hogs. Anyawy, I ended up getting a katz 1000W circulating heater. I figure even 30 minutes with it on should give the coolant a good boost in temperature. To go along with it, I got a remote control switch for it. So, I get up in the morning, turn on the block heater, get ready and go out to a warm car.

Thanks for the info. I ended up ordering a Kat's frost plug heater that fits the Aveo, so we'll see how it turns out. Only one Chevy dealer around here could find the factory block heater in the computer system, and they wanted $80 for the plug and an additional $60 for the cord, with a wait time of at least 2 weeks. Ordered the Kat's version on Amazon for less than $30 and they'll have it to me on Monday, more than enough time to get it installed.

What's the wattage of the one you ordered? That'll be the biggest factor in how well it works. I'm guessing it's ~350w.

It's unlikely you'd have any trouble starting your car where you're going without a block heater, as long as your battery is good.

But a heater is much better for the engine than an extreme cold start - warm oil gets circulated where it's needed much more quickly. I can hear the difference in the engine sound at start-up between a (very) cold start compared to a start after using a block/coolant heater. Also, it's nice to have cabin heat within a couple of minutes of starting up.

I've been using a block heater for years. I'm a fan of the inline tank-style circulating heater, mostly because they come in the most powerful versions. Which means the coolant gets warmer, and you don't have to plug it in for as long. I've got an 800w one now. Was using an external, bolt-on element style OEM heater that was 350w before.

Nemasys: I've heard that rumour before too - about block heaters "spoiling" a car. It's not true. When I asked for an explanation, there wasn't one. The only possible one I can think of is an engine that is in really bad shape (tune) may start with help from a block heater, but not without it. But that's a basic maintenance issue, not a block heater issue. Like you said: good spark & a strong battery.

I know this is an OLD thread, BUT any update on this?

I'm considering buying some sort of heater for Chewy, I would love to go out to a warm car. As Metro said, warm starts are better cold starts.

Yeah, I'd love to go out to a warm car in winter, too. It depends upon what you expect a "warm car" to be. If you want to go out to a warm car in winter you will need to move to a warmer place - like Florida.

From your latest posts, apparently you don't have the car garaged and you would need to run a power cord out to where it is parked to warm it electrically. Virtually any car will start in temps down to zero degrees F if the car is in good roadworthy condition. If it's much colder where you are on a regular basis, then a block heater is recommended. Short of that, you might try insulating the engine compartment and using a 100W, politically incorrect light bulb. Incandescent bulbs put out more heat than light. It will provide some warmth and raise the ambient temp under the hood. Remember, cold is cold and winter is winter, but it's all relative - compared to WHAT?. 20 degrees F is more comfortable than 0 degrees F. Either way you will need to deal with the nuisance of the power cord and the added expense to your electric bill.

Another option would be to buy heated clothing (Gerbings) and plug your outfit into the cigarette lighter on your car. As long as the car starts, you'll be warm. But heated clothing doesn't come cheap.

Hat, scarf, gloves, long underwear, boots. We can hardly wait for winter...

Thanks for the input. It is usually like 30 degrees here, it is rarely colder than 20. I think I'll wait beings how it doesn't get extremely cold here, and I always let Chewy warm up some Before I blast off to class.

Thanks,
