Why Does A Vape Pen Get Hot?

Why Does A Vape Pen Get Hot?

Vaping relies heavily on heat. It converts your substance to vapour, causing your device to generate heat. When you're new to vaping, however, it might be difficult to tell what typical heat is and what isn't. Is it true that some regions get hotter than others? When is it too hot? Why Does a Vape Pen Get Hot? And is there a method to cool down my device if it becomes too hot?

Where Is The Vaporizer's Heat?

If your device is hot, the first thing you should do is figure out where the heat is getting from and where it is going. The mouthpiece, vape tank, or chamber (where the coil connects) or the battery are the most common sources of heat. Keep in mind, though, that heat does not stay in one area. Heat has the ability to go from one location to another. As a result, identifying the specific spot where the heat is originating from may not always be easy.

Is There Such A Thing As Too Hot?

After you've determined where your device is becoming hot, consider how hot it is getting. The coil, for example, will generate heat. The coil is made to heat up. However, there is a distinction to be made between the heats that your equipment should create and when it becomes too hot. While different parts of your device may become hot to the touch, this should not be to the point where you can't even touch the region for a few seconds. When it gets to the point where you can't touch it, it's usually a symptom of a more serious problem.

Reasons Why Your Vape Is Hot And How To Fix It

Today, we'll go over the reasons why Vapes get hot and give a couple of solutions.

  1. Hot Coils/Chain Vaping

The coils become hot while you smoke. Temperatures commonly reach 3000 C or even higher. These pieces are designed with insulation so that you don't feel the heat as intensely through the casing. However, if you're having issues with a hot vape, the coil is most eager to judge - especially if you're into chain vaping.

This means that you vape continuously and for long periods of time. As a result, the coil does not have time to cool down, and the temperature rises with each vaping session. The heat will eventually make its way to the outside. The heat will be focused at the base, but the vape's body will also be heated.

The type of coil you're using can also play a role in the issue. Clapton coils, for example, burn hotter than normal coils. The more complicated a coil is, the more heat it produces. And, while this may be ideal for heavy smokers who like to blow large amounts of vapour, you should be aware of their heat potential.


Because it isn't really a problem, this is the most common and easiest to correct issue. Simply ensure that you take 10-minute breaks, and the issue will be resolved.

  1. Gunk Coil

Gunk can build up around the coil, stopping it from effectively wicking e-juice. The coil will normally overheat without producing a lot of vapour as a result of this. Because the wick material isn't coated with e-juice, you'll get dry puffs. The wick material will burn if you keep using the vape in this situation.


The quickest approach to fix this issue is to get a new vape coil kit. If you don't want to, you can clean the coil instead. Remove the dirt from around the coil, and you're ready to go. Of course, this will not be as effective as a fresh coil because a coil can only clean itself so much. It also takes a long time for the coil to dry and become used again.

  1. Juice Flow Is Restricted

A wicking issue is caused by gunk in the coil. Other reasons, such as restricted e-juice flow, can also produce a similar issue. This could be due to a design flaw in the tank or the thickness of the e-liquid. VG has a higher viscosity than PG. As a result, e-liquids with a higher VG content (typically greater than 70%) suffer wicking issues.

Some tanks, on the other side, have flow control. The channel between the wick and the tank is closed or limited using this technology, resulting in limited juice flow.


Open the flow control on your tank if it has one. If the VG ratio is too high, you should either switch to a sub-ohm tank and keep using the e-liquid or get a different e-liquid with a lower VG percentage.

  1. High Wattage/Coil Type

You can experience heat issues if your wattage is too high, or if you're using a complicated coil, like as a tiger coil or a Clapton coil. These items must be controlled with carefulness.


Even though they have thermodynamic cooling, you might try lowering the wattage. This, however, will lengthen the time between firing the battery and creating vapour.

  1. Airflow

Instead of criticizing the tank or the vape, examine the wattage and airflow combination if the vapour is too hot. High wattage causes the coil to become extremely hot, resulting in hot vapour. Cool air from outside interacts with the vapour to cool it when the airflow is opened.

The vapors will be too hot if the airflow is blocked.


To cool the vapour, adjust the airflow to allow more cool air in. If you have a second mouthpiece with airflow slots, you can also use it to chill the vapour. Don't forget, however, that you can still reduce the power.

  1. Hot Batteries

When your vape becomes hot, it's usually not the battery that's the issue. As a result, the above solution will fail. In the rare case when the battery is the source of the problem, you should act quickly. E-cigarette batteries are made to withstand temperatures of up to 600 degrees Celsius. When a battery is in operation, the insides might become significantly hotter. Internal temperatures should not exceed 780 degrees Celsius.

As a result, by the time you notice the heat from the outside, the inside of your vape is already heated.

When you see this, take the following precautions:

  1. Stop vaping and keep your mod away from anything flammable.
  2. Remove the battery from the vape tank and disconnect it.

Unfortunately, there isn't any other option than to obtain a replacement.
