Convection vs Conduction vaporizers, what you need to know

Dry herb vaporizers come in all different shapes and sizes; however, the two methods for creating vapor are usually the same. In this post we are going to talk about the differences in Convection vs Conduction. 

convection vaporization

Convection means hot air passes though the chamber to create vapor

Usually there is a heating element below the chamber. When you inhale hot air flows through the chamber creating vapor. For portable vaporizers convection is the new kid on the block. Most portables are conduction, however, that trend is changing as convection technology gets better and better.

Advantages of Convection vaporizers:

– Flavor quality
This is the biggest win for convection vaporizers; the flavor quality is superb. With conduction vaporizers your herbs are constantly heated. Convection only heats your herbs while in use. Not only will your herbs taste better, the left over AVB has less of a “popcorn” taste than conduction which is great for cooking.

– Most efficient with your herbs
Conduction vaporizers are constantly heating your herbs. Convection only heats your herbs while in use. This means your herbs are only extracting vapor when you want it to without any idle cooking.

Disadvantages of Convection vaporizers:

– Battery life
And what a drag it is. Convection takes up more energy than conduction which means less battery life for pure convection vaporizers. Luckily, batteries are improving and so are the convection heating elements. Future convection vaporizers will have more efficient heating elements and larger capacity replaceable batteries.

– Learning curve
We spend a lot of time talking to people who are buying vaporizers for the first time. If you are new to vaporizers you are more likely to return a convection vape than a conduction vape. The most common return reason is “it’s not producing vapor”. Air passes through the herbs which takes a few moments before producing vapor. If you are used to smoking from a pipe or rolling then you are probably expecting to take a small draw and blow out a large cloud. This isn’t how convection vaporizers operate. Pure convection takes a long draw to produce vapor. You will definitely get a nice big cloud if you take your time; however, the learning curve is there.

Also, because convection is a hot stream of air it tends to miss the inner part of your herbs. So halfway through your session you usually need to stir the chamber. This isn’t a huge problem and some manufactures are already working on solving this issue.

– Heating elements take up more space
Convection heating elements usually sit below the chamber; this takes up more space than your standard conduction element. This is why ultra compact vaporizers like the PAX use conduction. There isn’t enough room for the larger convection heating elements.

– Cost
This probably wont be the case forever but currently good convection vaporizers cost more to make, mostly because the technology is still changing and the heaters require stronger batteries.

conduction vaporization

Conduction means the chamber gets hot to create vapor

With conduction vaporizers the chamber itself works as the heating element. The walls of the chamber heat up which in turn heats your material and creates vapor.

Advantages of conduction vaporizers:

– Efficient use of energy
Power conservation is a difficult thing when you are creating heat. Conduction vaporizers usually have significantly more battery life than convection. Most conduction vaporizers use ceramic, borosilicate glass or stainless steel for their chambers. These materials are sturdy, inert and get hot fast which make them ideal.

– Smaller
Convection heating elements usually sit below the chamber taking up more space. Conduction heating elements are the chamber which makes them a lot smaller. Mini vaporizers like the DaVinci IQ and PAX 2 / PAX 3 utilize conduction.

Disadvantages of conduction vaporizers:

– Flavor quality
There are lots of conduction vaporizers that produce great flavor but convection is king when it comes to flavor quality.

– Constantly cooks your herbs
Airflow is always what creates the most vapor; however, conduction chambers are still hot and cooking the outside area of your herbs even when you aren’t inhaling.

hybrid vaporization

Ok, lets talk about hybrid chambers:

These are your harder hitting vaporizers, the ones that fill up a water pipe with little effort like the Mighty or the CFX.
Hybrid heating elements use both Convection and Conduction:
Hybrid heating elements vary a lot. The ratio between convection and conduction is slightly different on every vape. The new Fog by X-MAX for example has a 80% convection 20% conduction ratio. Upcoming vaporizers such as the CFX v2 let you adjust between convection and conduction so you can decide what works best for you.

Advantages of hybrid vaporizers:

– Powerful vapor production
If you are using both Convection and Conduction, you end up with a mix of the same advantages and disadvantages mentioned earlier. The one huge advantage hybrid vaporizers have is vapor production. You get lots and lots of vapor with hybrid chambers. That might not be everyone’s cup of tea, though if you like larger water pipe rips then hybrid heating is the way to go.


It’s not fair to say one heating method is better than another. What matters most to me might not be the same thing that matters the most to you. If you are looking for an ultra discreet vaporizer then conduction is probably the way to go. If you are all about the flavor, convection is awesome. If you like monster clouds give hybrid vaporizers a try.

    The Arizer Air gives me monster clouds daily. It is a mix of convection & conduction. I'll guess 70/30. Cleaned & reloded in 10 seconds! Best vaporizer in my opinion! I did a lot of research before I bought my Air. I see hundreds of happy people using the Air.

    Small correction. You say "Most conduction vaporizers use ceramic, borosilicate glass or stainless steel for their chambers. These materials are sturdy, inert and get hot fast which make them ideal." Ceramic and Stainless steel both have a high thermal capacity but low conductance which means it takes along time for them to heat up and they stay hot for a long time (most likely a the same for borosilicate glass. Unfortunately this also means they do not conduct their heat to the plant matter very well either. Aluminium on the other hand has the opposite properties hence why it seems to help in convection vapes to increase vapor production due to the fact that it readily transfers it heat to the plant material giving you a hybrid effect.

    Nice to see an article that wasn't all rah rah rah convection. The hybrids are IMO the way to go. An advantage you failed to mention with hybrids is you can get big, tasty coulds at lower temperatures, increasing flavor even more. I find, owning several vaporizers of all three types, ther hybrids to be superior to all other for flavor. I recently bought a CFX and was amazed at the flavor. I've considered the "great flavor debate" to be all hype and bs, but after owning 12 different vapes, the flavor brought forth by the CFX amazed me! Until this vape, and I've ownec"the best", such as Mighty and Pax, I was unimpressed, if you vaped one, you'd vaped them alll...... And the taste form conduction can be as good as convection, its all marketing bs. That hot air element is still pouring heat into the base of your chamber as long as the element is powered, in fact, the heat at the base is likely about as hot as the walls of a conduction vape!
