How to Prime a Vape Coil

Vape coils are one of the most hardworking parts of a vape device. As long as you’re vaping, a coil is toiling away, turning liquid into gas. When you’re not, they are susceptible to build-ups of e-liquid and clogs. Due to a combination of build-up and constant use, coils need changing quite a bit – depending on how frequent a vaper you are. 

When you do get around to changing your coil, it will need a bit of preparation. We call this process ‘priming’. Further to this, it isn’t only when you renew your coil that this is required. Wherever there is a fresh, brand new coil, you’ll need to prime it. As such, you should take the opportunity to prime the coil of any new vape device or tank.

What is a coil? 

A coil is the crucial part of the vape that produces the vape cloud in the most immediate sense. This part most often refers to two elements that come together – a wire and something called a wick. The wick is the part of the coil which is soaked in e-liquid and is often made from a woolly-looking substance covered in fibreglass. The wire heats up and, contacting the wick, produces the vapour, which is inhaled. Sometimes, the coil is called an atomizer – despite the latter differing slightly from a coil.  

How long does a coil last in a vape?

The longevity of your coil depends on how frequent a vaper you are. If you’re an avid vaper, the amount of cooling down and heating up your coil does across time will speed up its degradation. Such degradation could be worsened by not allowing the coil to soak up e-juice again. It is advised that you leave some time between hits to get around this.

Changing your coil should begin when you start to detect that it has stopped performing as well as it should. There are a few giveaways for which you should look out. 

If your e-juice begins to taste a bit odd, you’ll know that your coil may be in need of a bit of a refresh. The taste of the e-liquid might have changed in a couple of ways, the most likely being that the vapour has started to taste burnt or charred. The second giveaway in taste is that the e-liquid does not taste as punchy or flavoursome as it should. 

Bubbling sounds is another significant indication that the coil has stopped working properly. The coil might be the first port of call when solving the gurgling sound in your device – but it might not be the only factor in this issue.  

This may also be a coil issue if your vape has begun to produce significantly thinner or more dispersed vapour. Again, you might be best checking the battery level of your device and whether it is an issue that can be solved by replacing the power supply. 

Changing your vape coil

  1. Before doing anything, you’ll want to prime your new coil – something you won’t know how to do till later! Being prepared will cut down the amount of time you’re waiting about before you install your new coil.
  2. Take apart your vaping device. This step might be a bit fiddly, but it shouldn’t be too difficult. Vape devices have parts that are designed to be exchanged, upgraded and renewed, so disassembly should be straightforward. If you have kept your vape’s instructions, they might come in handy at this point.
  3. Next, you’ll need to drain the tank. Changing your coil is best when there is no e-liquid left. This also prevents the flavours from mixing if you’re primed the coil with a different flavour. Trust us; nobody wants to experience a Crispy Coffee mixed with a Lemon Mint!
  4. Attach your newly primed coil. The coil shouldn’t be difficult to screw back into place. As with tanks, make sure the threads line up. After you’ve put the coil back on, you can fill the tank with the same e-liquid as you soaked the coil in and be good to go!

What IS the process of priming?    

The point of priming is to avoid the coil from heating up and essentially vaporizing nothing. This could have detrimental effects on the coil and might prevent it from working fully or even ruining the coil completely. Persevering with a compromised coil might also contribute to your e-liquid lacking taste or tasting burnt – not something that is recommended! Simply put, the process of priming refers to soaking the coil for a sufficient amount of time to ensure the wick is fully saturated with e-liquid.

Priming your coil, a step-by-step guide

Once you have fitted your new coil into your tank, either pop a few drops of e-liquid into the opening at the top of the coil or into holes at the side. With sub-ohm coils, it’s recommended you add a few extra drops but ensure you don’t over-saturate the coil and end up with a mouthful of e-liquid!

  • Now you are ready to fill up your tank, ensuring the wick is fully immersed.
  • After 15-30 minutes, your device should be ready to use. However, if you are using the high VG e-liquids, as they are thicker, you may need to leave it soaking longer.
  • In order to draw the e-liquid up the wick, inhale a couple of times on the mouthpiece WITHOUT holding the button. Avoid doing too much or you may end up with a mouthful of e-liquid.
  • Now you are ready to start vaping!
  • For the first couple of inhalations, use a lower voltage and take a few quick hits. This means avoiding taking the vapour down to your lungs by inhaling and immediately exhaling again. After this, your coil is fully primed and ready to use.
