7 Easy Ways To Stop Your Coil From Burning

Here’s a quick review of this new e-juice I tried. It’s called “Mèche Brûlée.”

On the nose, you’re struck with the delicate flavour of a smouldering stack of old newspapers, and it’s accompanied by the inimitable sensation of somebody sandpapering the inside of your nostrils until the heat from the friction almost starts to burn.

The feeling going down is akin to somebody raking the back of your throat with a hot cheese grater, and the taste filling your mouth conjures up images of those choking, noxious knockout gases you always see in the 60s Batman series. You know, the ones that are faintly purple and cause the dynamic duo to clutch their throats and fall to the ground, gasping for air.

Wait a minute, “Mèche Brûlée” isn’t an e-juice at all; it’s just a clumsy, Google-led translation of “burnt wick” into French. And yes, that’s exactly the taste you get from a burnt coil, or more specifically, a burnt wick. As if the horrendous taste wasn’t enough, it also ruins the whole coil head and costs you money.

The good news is that by taking a few simple steps, you can stop your coils from burning out, or at least make it a lot less likely.

Hang on, how do you tell if your coil is burnt out?

If your coil is truly burnt out, you will know about it – the taste of Meche Brûlée is truly unmistakable!

If your coil is only slightly burnt, you may get a slight burnt taste, as if something’s not quite right. Given that we know that burnt coils can produce harmful chemicals, you should probably still change it.

Occasionally, you’ll also get a burnt taste when you have just replaced a burnt out coil. Sometimes this will disappear after a few puffs, but at other times you may need to replace the e-liquid.

Why Do Coils Get Burnt

If you want to avoid burnt coils, the most important thing to understand is why coils get burnt in the first place. This is really simple and it underpins all the advice given in this post.

First, think about when you’re vaping but not getting a burnt taste. When you hit the fire button, electricity flows through your coil and it gets hot. The heat given off by the coil is taken up by the e-juice, which is soaked into the wick, and it turns the juice into vapour. Because you have the juice there to take up some of the heat energy given off by the coil, the temperature of the coil doesn’t get too high.

When the juice in the wick has been vaporised, the wick dries out a little. However, you have a tank full of e-juice surrounding the coil, and this is constantly replacing the juice in the wick. This means that by the time you go to take another puff, the wick is soaked again and everything works as it should.

But what happens when there’s no juice in the wick, or just not enough? Now, when you hit the fire button and the coil heats up, there isn’t much there to take up that additional heat. As a result, the temperature of the coil increases. This leads to two (equally unwanted) things happening:

  • The juice remaining in the wick gets “overcooked,” heating up to an excessive degree and causing the PG to breaking down into formaldehyde. In case this needs clarifying: formaldehyde tastes absolutely gross.
  • Without anything to protect it from heat, the wick is directly exposed to the glowing-hot coil. Since it’s probably made of cotton, the wick burns. If the wick was completely dry, it would literally erupt in flames. And yes, burning cotton tastes horrible too.

These two things are the key ingredients in the “Mèche Brûlée” e-juice described in the introduction. Burning cotton with notes of formaldehyde. Disgusting with some extra-disgusting thrown in for good measure.

So How Can We Stop Our Coils From Burning Out?

Well, from the above, it’s clear that the key thing we need to ensure is that there’s always juice in the wick when we vape.

This means you shouldn’t “dry burn” your coils, because most wicks are made from cotton and will simply get ruined without juice there to protect them. For ceramic wicks, dry burning is fine, and you can get away with short bursts for silica, but not for cotton.

There’s less of a risk when you have juice in your wick, but you still have to take some steps to protect your coil. When you hit the fire button, you deplete the juice in the wick, and we need to make sure our devices are set up so that the flow of new e-liquid can keep up with the rate we’re vaporizing it.

That’s the key point for how to stop your coil from burning. But what does this mean from a vaper’s perspective? What do we actually need to do?

7 Ways to Stop Your Coil From Burning

1 – Prime Your Coils Before VapingPriming a coil

If you don’t “prime” your coils before you start vaping, you can burn your coil before you’ve even gotten any use of out of it.

When you first install a new coil, the wick has to go from being completely dry to completely soaked. This takes time, so you usually have to wait five minutes or so between filling up your tank and taking your first puff. If you wait long enough, priming isn’t strictly necessary, but the problem is that it’s really hard to tell whether your wick is completely soaked. And if it isn’t, when you press fire, there isn’t enough juice there to absorb the heat, and this causes the problems described above.

Priming your coil is just manually soaking the wicks before you install it. Coil heads tend to have an opening in the top and some ports around the side where the wick is visible. To prime the coil, add a few drops of e-juice to the opening in the top (around 3 to 5 is enough) and then soak the exposed wick at the ports around the side. This doesn’t take much for each port, but just ensure the parts you can see are saturated with e-juice.

Alternatively, some vapers take a few puffs on their e-cig without pressing the fire button as a method of priming the coil, which forcefully sucks e-liquid into the wickl. Be careful if you try this, though, because if you do it too much it can flood your coil.

Now your new coil is ready to go. But, as an extra precaution, it’s still better to wait about five minutes after you fill up your tank before you start vaping. This shouldn’t be needed (since you already soaked the wick), but if you don’t prime your coil properly the whole thing can get ruined, so it’s worth being absolutely sure.

2 – Stop Chain VapingDon't be a steam train

“Chain vaping” – just vaping and vaping continuously until you can’t see your e-cig for all the clouds – can lead to a burnt wick too. The reason for this is the balance mentioned earlier: you need to ensure that your wick can re-saturate with juice before you hit the fire button again. In normal use, this isn’t a problem, because you’ll stop vaping after a short session and give it time to recover. However, if you’re continuously vaping for a long period of time, eventually your wicks will dry out. Then if you vape again you’ll risk burning the wick.

The solution to this is simple: stop vaping for a little while. The biggest sign that you need to stop is diminishing flavour. This is a sign there isn’t much juice in your coil and you’re approaching a burning situation. Your wick needs time to get soaked again, like a “re-priming.” Since the coil will be hot, the simplest thing to do is just stop vaping for 5 to 10 minutes and let your tank do its job.

3 – Reduce Your Power SettingTemperature Display

When you vape at a higher wattage, you vaporise more juice with each puff. This is great if you want big clouds, but it can also impact your coils. Since you’re vaping e-juice at a faster rate, sometimes your wick struggles to soak up juice quickly enough to keep up. And when it can’t keep up, you can burn your wick. It’s a lot like the issue with chain vaping, except it happens after much fewer puffs.

The solution is to just reduce your power setting. If you notice the flavour dying out, then your coil is probably getting dry and needs time to soak up juice. You’ll need to have a break (as above) when this happens, but to make it less likely to happen again, just reduce your wattage a little bit.

Ordinarily, there will be some indication of the range of wattages you should be using on the coil itself, so if you stick to this range you shouldn’t run into issues. It’s best to start at the lower end and work your way up. However, if you’re experiencing loss of flavour and your coils are burning at your current setting, decreasing the power is the simplest solution.

4 – Keep Your Tank Topped UpFull Tank

If the amount of juice in your tank is low, it might not be able to soak into your wicks as well. On many coil heads, the juice has to be at a certain level to even reach the wicking ports. When less of the juice is in contact with the wick, it doesn’t get soaked up as quickly. When your juice level is really low, this can cause problems very easily.

The simplest solution to this is to keep your tank topped up. When the performance starts to get worse and the flavour diminishes, it’s probably time to give up on the juice in the tank and refill. You can empty it out first if you don’t want the flavours to mix (although I usually don’t bother). Alternatively, you can often rotate your tank so the liquid does soak the wicks. This is less reliable, though, and it gets really hard when your juice level gets too low, so refilling is the best approach.

5 – Use an E-Liquid with More PGHalo E-Liquid with the good PG

PG is thinner than VG, and that means it soaks into wicks more easily. This has important consequences for that balance we need to strike between the speed of wicking and the speed of vaporisation. If your juice doesn’t soak into the wick as quickly, you’re more likely to run into dry puffs and possibly burn your wicks.

This means that juices with a high VG content (70 % or higher) can cause problems with wicking and may ruin your coils. So if you’re regularly running into issues with dry puffs and burnt coils, it could be the e-liquid you’re using. Try changing your high-VG e-liquid for one with around a 50/50 mix or primarily PG.

This isn’t always a problem, though. Sub ohm tanks, for example, are often well set up to deal with higher-VG juices. However, if your tank doesn’t have excellent wicking, they could easily cause an issue.

6 – Try an E-Juice With Less SweetenerSugar on Spoon

When an e-juice has a lot of sweetener added, it can “gunk” up your coils. The sugars in the e-liquid can caramelise, which is delicious if you’re talking about a dessert, but it’s also a reliable way to destroy your coils. The gunk-filled wick can’t soak up new juice as well, and so when you vape, you cause the same sort of problems discussed throughout this post.

Although this is often related to sweetener, there are many different juices that are prone to gunking up coils. Coffee and heavy, dessert-inspired e-liquids are common culprits, but there are others too (discussed in threads here and here). In general, darker-coloured juices are more likely to impact your wicks and coils than clearer juices.

If you have a gunked up coil, you can clean the wicks to attempt to solve the problem, either using water or some strong grain alcohol (or anything clear, strong and drinkable – not rubbing alcohol). If you do this, though, you have to leave it for 24 hours (or longer) to completely dry out before you use it again.

Not everyone agrees when it comes to cleaning coils, though. Not only are there different methods, a lot of the time you still won’t be able to get the coil back in tip-top condition even after a thorough clean. This is especially true if you’ve already tried to vape with the gunked up coil and damaged the wick in the process.

Really, the easiest solution is to just use a different e-juice without as much sweetener in. You’ll have to sacrifice the coil that’s already gunked up, but it will help you avoid the issue altogether in future.

7 – Use Temperature ControlInnokin Cool-Fire TC100

Temperature control (TC) vaping solves the problems with burning wicks more directly. By tracking the detectable changes in resistance that occur when certain coil materials are heated up, TC devices such as the Innokin Cool Fire IV  allow you to set a maximum temperature for your coil.

When it reaches this temperature, the e-cig stops delivering power to stop it from getting any hotter.

If there was a “magic bullet” solution to burned wicks and coils, TC is it. When you try to vape from a wick without enough juice in it, the device doesn’t let you. Even if you were actively trying to burn your wicks, you couldn’t do it. This means TC can solve the problem without the need for any of the other tips in this list. The only problem is that you need a compatible e-cig and a tank that supports nickel, titanium or stainless steel coils.

Saving Your Money and Your Tastebuds

Although it seems like a lot of things to keep track of, this is definitely an area where it’s worth going to some effort to protect your coils. Every burnt coil and wick is money wasted, because there is no going back: you have to use a new atomizer head. This is especially true if you forget to prime a coil and ruin a brand new one. Plus, it tastes so disgusting it will probably mentally scar you for life.

So if you want to enjoy your juice, get the most out of your coils and avoid the taste of burning wick, keep these tips in mind when you’re vaping.

  1. The advantage of a rebuildable atomizer tank (as opposed to all in ones and often proprietary coils) is that you can remove the cotton, dry burn the coil (as opposed to a coil/wick combination “coil”) and replace the old cotton. This allows you to remove built up “sweeteners” or burnt solids from the coil and export those also trapped in the cotton wick. In a rebuildable tank, you’re able to simply reuse your coil and consume only cotton. It reduces your coil costs and empowers you to rely on less materials/vape shops for coil replacements due to it’s modular nature.

    I often use sweet vape juices that leave a solid buildup on my coils that I can taste at a certain point – enter jank flavor… Then it’s time to replace cotton, clean the coil and refill for more sweet tasting vapes without a trip to the vape shop, provided I have cotton.

    1. Excellent point – the rebuildable heads are the most economic way to go.

      Just a couple of other points:

      1) Any cotton will work, I have a thousand flat cotton pads from the dollar store that I cut into small strips – many years supply for only a buck. Dry burning the coil also extends life dramatically (indefinitely?).

      2) The OP very accurately pointed out that overheating caused by juice starvation is the cause of “Mèche Brûlée.” (lol).

      3) The temptation is to stuff as much cotton through the coil that you can. This starves the coil, which burns the cotton.

      4) I found that making the cotton strips (wicks) as thin as possible produced more vape much quicker, and prevented starvation and burnt out. So thin wicks last longer and are more power efficient!

      5) The best part is, you can bump up the power to the coil, which gives even better vaping!

      It is all about keeping the coil soaked and the juice flowing freely.

  2. I have been burning through coils like crazy! Makes me so MAD! (I have an Evic VTC Mini with Cubis Kit by Joytech 75W Temp Control.) Are there different brands of coils that are, maybe, better or more durable? I will definitely be soaking the bottom holes in the coil from now on. I did not know about that. Maybe i puff too much. …
    Bummed

    1. Soaking the coils first makes a huge difference – if you are using them at a high power you will almost certainly burn your coils if you don’t prime them first. I also burn through them much faster when sub-ohming – when using higher resistance and lower power I find they last for ages.

  3. I’m getting so fed up, wasting half my coils 🙁
    I try “priming” the new atomizer on my mini melo 3 tank, then fill the tank and leave it an hour before i use it. But it’s still 50/50 wether it works properly or I get that disgusting burnt taste and have to throw the brand new coil away and start again!
    It happened with my previous istick basic too! I just can’t see why I keep messing it up :/
