If you've been vaping for a while then you’ve probably experienced the terrible taste of a burnt coil in your e-cig - enough to make you try anything to prevent it happening again. Alternatively, if you haven’t burnt a coil to date, then you’re probably keen to avoid it ever happening.
In that case, you need to know the best methods and tips to keep your coil from burning and this guide contains all you need. Whilst it can change from device to device, this is the best all round advice and can be used to generally improve the health of your vapourisers.
Signs a coil is burnt
The coil is the replaceable part of the e-cig that heats the oil to create the vapours, a vital part of the device. Here’s how you can tell if it’s on the way out or has indeed burnt:
- No matter the flavour of your oil, you taste char and burning
- You feel like someone is scratching the inside of your nostrils T
- he coil looks visibly burnt on inspection
Aside from being unpleasant, it can actually cause the release of harmful chemicals so a replacement needs to be found as soon as possible. It’s best to take notice of the early symptoms - tasting burning - and switching it out before it gets worse.
Why do coils burn?
Coils work hard every time you puff on the e-cig with electricity flowing through them, making them go hot. However, as they release some of this heat to the e-liquid, they don’t normally overheat.
The issue begins when the e-liquid starts to run out and doesn’t fully surround the coil and wick. When the liquid depletes, there isn’t enough oil to take up the excess heat, so the coil overheats and burns.
At the same time, the horrible taste you’ll experience is compounded by the wick also overheating and burning as it has no oil protecting it from the full heat of the coil. Not pleasant at all.
Top tips to stop your coil burning
Basically, we don’t need to convince you that you want to take care of your e-cig so you don’t suffer from the foul taste brought on by burning coils. Here’s how you can prevent it:
Don’t chain vape
Continuously vaping doesn’t give the wick the chance to re-saturate with e-liquid, so it becomes dry and likely to burn, affecting the performance of the coil. You’ll know if you’re chain vaping but a clear sign that the wick is burning is a reduction in flavour, as it highlights it doesn’t have enough contact with the e-liquid. This will make the coil heat up as well and have a knock on effect. If you stop vaping for ten minutes, maybe five, then the tank will work it’s magic without you having to worry.
To prime a new coil before you vape, you need to ensure the wick is completely soaked with the e-liquid you’re using. This can involve waiting several minutes and not vaping from it straight away after installation, however the way to prime your coil is by manually soaking the wick beforehand. This way there’s no doubt of guesswork. To do this, soak the visible parts of the wick with a few drops of e-liquid before attaching the cartridge; there are normally ports where you can see the wick. On top of this, wait around five minutes to fill the tank just to be sure.
Top up your tank
Refill the tank as required so the levels don’t get too low. It’s another way to keep maintaining the quality of flavour and to ensure the wick doesn’t get dry and burnt. Reduce power If you're e-cigarette lets you change the power setting, try to keep it on low or start low and work your way up to higher temperatures. The higher the temperature you vape, the more oils you take up with each puff, which can leave the wick exposed - similar to chain vaping.
If the flavour seems to reduce, or have a quick break to give the wick a chance to soak up the oil again. Check the wattage indicated on the vape oil as a rough guide.
Sweeteners clog up coils as they caramelise under the heat. When the wick is clogged it can’t soak up anything else so will again, be unable to handle the heat and will in turn gunk up the coils further. It’s a lose, lose situation. To avoid this, check the sugar and sweetener content of your refills and try to avoid the more dessert based flavours. Annoyingly, if this happens, even if you take the time to clean your coil with grain alcohol, it’s still not going to reach the glory of it’s former performance.
Choose higher PG e-liquids
Propylene Glycol e-liquids are thinner than Vegetable Glycerin versions so put less of a strain on the coil and help to balance the speed of evaporation. A good mixture is a 50/50 PG VG oil. Any VG oils over 70% are likely to cause issues.
Better temperature control
Perhaps the easiest solution is to get hold of a temperature control device that will monitor the heat and set a maximum temperature for your coil. This would give s you peace of mind so would be a wise investment if you feel overly concerned. After you create the setting, it will stop delivering power at the maximum temperature and stop it burning out.
Follow this advice and you won’t have to worry about the quality of your vaping experience. It’s all about being aware and maintaining your device as you go, keeping up with refills and not using it excessively. It may seem like a lot to take on, but it saves you a lot of hassle in the long run and saves you money.
