Closed versus open system in e-cigarettes - how do they differ?

E-cigarettes, like many other devices and products, are available in various versions - this is due to their adaptation to the needs of each user. We can find a lot of differences between the various models of e-cigarettes, but today we will focus on the one related to the heater. What are e-cigarettes with closed and open heating system? How are they different from each other?

Electronic cigarettes - an alternative to classic tobacco products

E-cigarettes are an alternative product to regular cigarettes. Their use is associated with the absence of smoke and ash, and hence, the absence of all by-products of tobacco combustion. As for tobacco, we won't find it in electronic cigarettes at all.

E-cigarettes use a special liquid called a liquid. It is a mixture of nicotine, glycerin, glycol and flavorings. E-cigarettes use a plant-based nicotine solution, so you don't have to use real tobacco - nicotine is the main reason you use tobacco products.

The liquid in e-cigarettes is heated by the heater and it depends on it whether we are dealing with an open heating system or a closed heating system. Each of these solutions has its advantages and disadvantages - what are the differences between the two types of e-cigarettes?

E-cigarettes with an open heating system

Let's start with a general explanation of what exactly a heater is and how it works. The heating system or heater is part of an electronic cigarette that can be compared to an engine in a car. Fuel is supplied to the engine and is used to power the entire undercarriage. In the case of e-cigarettes, it looks quite similar - the liquid enters the heater, where it is then heated, which changes its state of aggregation to volatile.

The heater is usually made of a piece of cotton wool and a small wire that wraps it. In this case, cotton wool serves as the liquid's carrier, while the wire is a direct source of heat to heat the liquid.

Due to the nature of the e-cigarette's operation, the heaters wear out over time and need to be replaced. The heater can be a replaceable element or permanently integrated into the tank. The first case is precisely electronic cigarettes with an open heating system. Their characteristics are based on a replaceable heater, but the differences between a closed and an open heating system do not end there.

In the case of an open heating system, adding liquid to the e-cigarette is the responsibility of the user. When the liquid in the tank is running out, it may be necessary to open a special hole and add liquid. What does it look like for e-cigarettes with a closed heating system?

E-cigarettes with closed heating system

In the case of e-cigarettes with a closed heating system, it is not possible to replace the heater itself. Similarly, we cannot add liquid to them when it is finished in the reservoir. So what does the exploitation of this type of electronic cigarette look like?

The whole is based on cartridges, i.e. elements that combine the tank, heater and liquid. When all the fluid in the cartridge is used up, just change it to a new one. In this way, using an e-cigarette with a closed heating system is much less complicated than using an e-cigarette with a replaceable heater.

In electronic cigarettes for cartridges, the only intervention by the user is to unfasten the old cartridge and replace it with a new one. Therefore, this solution should be especially appreciated by those who value reliable equipment that does not require any complicated steps.

Closed and open heating system - advantages and disadvantages of both solutions
There are no perfect solutions in the world, and the same is true for e-cigarettes. Both a closed and an open heating system have their advantages and disadvantages that may disqualify it or make it stand out in the eyes of any user.

By far the biggest advantage of e-cigarettes with a closed heating system is their convenience. The user of electronic cigarettes of this type is only responsible for replacing the cartridge after its end. However, as a result, he has less control over his device.

With an open heating system, the e-cigarette user will have much more to do. Not only will he have to remember to refill the liquid regularly, but also to check the condition of the heater. The fact is that it is not necessary to replace it very often - one heater can fulfill its function for several weeks, if used in an optimal way - but it still poses a problem for the user. However, in return, he gets more control over his device. At the same time, liquids can be found in slightly more aromatic variants than in the case of cartridges.

As you can see, it is difficult to say unequivocally which type of e-cigarette will be more universal. Each user of e-cigarettes must independently decide on the choice of a heating unit, depending on their personal preferences.
