Conduction vs Convection Vaporizers

Updated: August 11, 2025
We break down the difference between conduction vs convection vaporizers. Learn what makes each heating method different and their advantages!

How Do Vaporizers Work? (The Short Answer)

The process of vaporizing essentially boils down to a three step process.
1. Applying heat to your dry herb.
2. That heat extracts essential oils from your dry herb
3. Those oils then turn into gas molecules, better known as vapor.
The result of this process is the formation of the vapor you inhale.

How are Conduction and Convection Vaporizers Different?

It’s easier to understand than you might think. The graphic below breaks down the basics, and when you pair it with what you’ve learned in this article, you’ll have a clear picture of how each heating method works. Once you know the difference, you can choose the style that not only delivers the experience you want but also helps you save money with vaporizers.
Conduction vs Convection Explained
There are usually two main types of vaporizers: conduction vaporizers and convection vaporizers. These two types of heating styles will make a drastic difference in the quality and flavor of the vapor produced. Our vaporizer buyer’s guide offers a good explanation for choosing the best heating style for your needs.
It is important to know the differences between them so you can make an informed decision as to which vaporizer is right for you.
We’re going to touch on the science (just a little bit, I swear!) and then go over pros and cons of both as well as some popular vaporizers that fall into each category.

The Science: Conduction vs. Convection Vaporization

How Does a Conduction Vaporizer Work?

Conduction heat relies on the transfer of heat through direct contact. Think of a sausage in a pan on the stove. The pan touches the hot element, and then the sausage absorbs that heat because it is directly in contact with the pan.
Conduction Heating Explained

Conduction vaporizers will most commonly use battery powered heating chambers – think of the Zeus Arc S Hub or the Pax Plus. You load your dry herb directly into the chamber, and when the chamber heats up, your dry herb heats up, releases the oils, and voila, vapor!

How Does a Convection Vaporizer Work?

Convection, however, relies on an element heating air that passes over that element. Think of that same sausage, but in the oven. There is an element at the bottom or back of your oven that heats the air inside the oven. That hot air cooks your sausage. In convection, air is used as the means of transferring heat to your sausage.
Convection Heat Explained
Convection vaporizers will either be powered by an internal fan like the Volcano Vaporizer or with the power from your own draws like the Utillian 723. Either way, the hot air moves through your dry herb, cooking and extracting vapor from it.

Pros & Con’s Of Conduction & Convection Vaporizers

There are pros and cons to both heating methods, so making the choice between these two vaporizing styles will depend on what matters most to you. Of course, the temperature you set your vaporizer is also important, be sure to check out our article on the best temperature settings for vaping to learn more!

Conduction Vaporizers: More Portable & Efficient Battery Life

Pros of Conduction Vaporizers

  • Smaller Footprint
  • More efficient; battery will typically last longer
  • Good vapor quality
  • Generally simpler to use

Cons of Conduction Vaporizers

  • Possibility of uneven vaporization

Conduction vaporizers are considered to be less efficient in vaporizing, since dry herb that is not directly touching the heating element can be unevenly vaporized.

Though this can be fixed by gently stirring your dry herb every so often to ensure every part of your batch gets equal “heat attention,” the dry herb directly in contact with the heating element will be at a higher risk of being over-heated, hence lowering the vapor quality.

The vapor quality of a conduction vaporizer is good, however, and if you stir your dry herb during a session, it will have no trouble extracting all of the essential oils from your herb to deliver you a quality session. Its also much faster at heating up then convection vaporizers.

Conduction vaporizers do not need as much space to generate heat and therefore are significantly smaller than convection units. The above Zeus Arc is one of the smallest vaporizers available, but can still put out big clouds.

Conduction units are also generally much simpler to use, as there is one less step in the heating process. Conduction allows for more efficient use of energy and these units generally last longer before the battery needs to be charged.

Good examples of conduction vaporizers are the already mentioned and depicted Zeus Arc GT3, which is super portable, has a gold vapor path and some fantastic vapor quality.

Convection Vaporizers: Better than Conduction?

Pros of Convection Vaporizers

  • Better vapor quality
  • Better flavor
  • Better Airflow

Cons of Convection Vaporizers

  • Larger & Bulkier
  • Typically more expensive
  • Generally harder to use
  • Battery typically will not last as long

 

Collection of Convection Vaporizers

Convection vaporizers are a tricky customer. The only real thing that they boast is better vapor quality and better flavor, but at the end of the day, that’s really the biggest thing you want in a vaporizer.

It does come at a price though, a larger footprint is needed because convection needs extra space to generate hot air. And this need to generate hot air results in a a higher energy cost to the battery. Also convection vaporizers tend to be more expensive, but their cost has come down in recent years, with the Utillian 621 being one of the most affordable convection vaporizers to date.

That being said, the vapor quality of convection devices is typically outstanding, because of the ability to evenly cook your dry herb.

Of course, a lot of your experience is going to come down to the quality of the dry herb product you have, but a good convection device can make a world of difference in terms of flavor and vapor quality.

You can’t talk about convection vaporizers without mentioning Storz & Bickel. Their iconic Volcano reigns as the best convection vaporizer and even the best desktop vape on the market – and since it’s inception 20 or so years ago, they have taken their technology and shrunken it down into two awesome portables, the Crafty + and the Mighty Plus. Although in today’s market, newer devices are also mixing both heating methods while still using primarily convection. Units like the Arizer Solo 3 or Tronian Milatron are great examples.

Both of these devices are ranked as some of the best convection vaporizers on the market.

Conclusion – Should you get a Conduction or Convection Vaporizer?

There are a lot of vaporizers on the market and ultimately it is up to you to decide which heating style fits your needs. Personally, I keep one from each category because it is nice to have options.

Conduction vaporizers shine when you are on the go. They are compact, heat up quickly, and slip easily into a pocket or bag which makes them great travel companions.

Convection vaporizers often work best at home. They tend to be bulkier, less discreet, and better suited for longer, more relaxed sessions. In return, they reward you with rich vapor quality and efficient extraction.

Just like with cooking, using the same method every time can become repetitive. Switching things up keeps your sessions fresh and enjoyable.

With so many devices to choose from, the key is to do your research and find the right fit for your lifestyle.
