Conduction vs Convection Vaporizers — What's the Difference?

Last updated: 18 June 2026

Quick version: conduction heats your herb by touch, convection heats it with hot air, and hybrids do both. Conduction is cheaper, faster to heat and easier to use. Convection tastes cleaner and treats your herb more evenly, but it costs more and often only makes vapour while you draw. Neither is “best”, they suit different sessions.

That’s the headline. If you want to actually understand what you’re buying, and why two vapes at the same temperature can feel completely different, here’s the long version. People search this under both spellings, conduction vs convection vaporizer and the s-spelling vaporiser, and it’s the same question either way.

How conduction heats

Think of a frying pan. The chamber wall gets hot, your herb sits against it, and the heat moves from the metal into the plant by direct contact. Whatever’s touching the wall cooks first and hardest; whatever’s in the middle of the bowl catches up later.

This is the older, simpler approach, and it’s what sits inside most pocket vapes. It heats up fast, often inside 20 to 40 seconds, and it holds one temperature for the length of a session, so you can draw however you like and keep getting vapour.

The trade-off is scorching. Leave herb pressed against a hot wall and not moving and the contact points darken and go bitter. It’s why conduction bowls reward a tight, even pack and a stir halfway through, you’re trying to even out a heat source that’s only touching part of the load.

How convection heats

Now think of a fan-forced oven. The vape heats air, then pulls or pushes that hot air through the bowl, and the herb cooks from the airflow rather than from anything it’s resting on. Nothing’s sitting on a hot surface, so there’s no scorching, and because the air moves through the whole load it extracts more evenly.

The reward is flavour and efficiency. The first draws come through clean and bright, and you tend to get more out of a smaller bowl because the heat reaches everything, not just the bits near the wall.

The cost is, well, cost, and a quirk. True convection is harder to engineer, so the gear is dearer. And a lot of convection vapes, especially portables, only heat the air while you’re actively drawing. That’s on-demand: no draw, no vapour. Brilliant for not wasting herb, but it asks for a slower, more patient pull, because the air needs a moment to come up to temperature as it passes through.

Hybrid: a bit of both

Most of the well-loved “it just works” portables are hybrids. A hybrid warms the chamber wall and pushes hot air through at the same time, so you get the steady, on-demand-able feel of conduction with a decent slice of convection’s even extraction and clean flavour.

It’s the reason a Storz & Bickel Mighty draws so smoothly and forgives a lazy pack, and why the Volcano Hybrid desktop can fill a bag without babysitting. You give up a touch of the absolute purity a dedicated convection unit gives you, and in return you get something far easier to live with day to day. For most people that’s the right trade.

The differences that actually matter

Forget the physics for a second. Here’s what you’ll notice in real use.

  • Flavour. Convection wins early. Clean, bright first draws, no toasty edge. Conduction can taste lovely too, it just slides into a roasted flavour sooner.
  • Efficiency. Convection usually does more with less herb because the whole bowl cooks evenly. Conduction can match it, but only with a careful pack and a stir.
  • Draw. Conduction is forgiving, pull how you like. On-demand convection wants a long, slow draw, rip it fast and the vapour comes out thin and cool.
  • Heat-up time. Conduction is quick, often under 40 seconds. Convection is usually a little slower to be ready, and on-demand units are “ready” only while you’re drawing.
  • Battery. Conduction sips, because it holds one temperature. On-demand convection gulps, because heating air fast on every draw is hungry work.
  • Price. Conduction is cheaper across the board. Convection costs more for the same vapour quality, and you feel it most in the portables.
  • Consistency bowl to bowl. Convection and hybrids are steadier. Pure conduction depends a lot on how well you packed it.

Real devices, so it’s not all theory

  • Conduction-leaning portables: the PAX range and a lot of the budget pocket vapes. Fast, simple, pack-and-go. The PAX rewards a fairly tight bowl and a half-pack with a lid for flavour.
  • Hybrid portables: the Mighty and Venty from Storz & Bickel. The benchmark a lot of vapes get measured against, smooth, consistent, hard to get wrong.
  • Full-convection portables: the Firefly 2+ and the TinyMight. On-demand, big flavour, the kind of vapour that converts people. Both ask for a slow draw and a bit of practice, and the TinyMight in particular can throw serious clouds once you’ve got the technique.
  • Convection-leaning desktops: Arizer units like the Extreme Q and the older V-Tower, with glass paths that taste clean and come apart for easy cleaning. The Volcano Hybrid sits here too on the premium end.
  • No electronics at all: DynaVap. You heat the tip with a torch and a click tells you it’s ready. It’s mostly conduction with some convection as you draw, no battery to die, near indestructible, and a genuine learning curve.

If you want the broader category map rather than just heating styles, the dry herb vaporizer guide covers the lot.

So which should you get?

A plain recommendation, by what you’re actually after.

Chasing flavour above all. Go convection. A Firefly 2+ for pocket use or an Arizer desktop at home. You’ll cop the slower draw and the higher price, and the taste pays you back every session.

You want easy and reliable. Hybrid, every time. A Mighty if the budget’s there, and you’ll spend more time vaping and less time fussing over how you packed the bowl.

On a budget, or it’s your first vape. Conduction. A solid mid-range PAX or a good budget portable teaches you what you actually care about without much money or much fuss. You’ll choose your second device far better than your first.

Best possible vapour at home, sharing with people. A desktop, the Volcano Hybrid or an Arizer Extreme Q. Mains power means the thickest, most consistent clouds going, and a bag or whip means everyone gets a turn.

You want something that’ll outlive your phone. A DynaVap. No battery, no screen, nothing to fail. Just you, a torch and a bit of patience.

Concentrates, not herb. Different game entirely, concentrate vaporizers work a lot hotter and need their own technique. The conduction-versus-convection split still applies, but the gear and the approach are separate.

Still weighing it up? The buyer’s guide walks the whole decision step by step, choosing a portable vaporizer digs into the pocket options, and buying your first vaporizer is the place to start if this is all new.

Frequently asked

Is convection better than conduction?
Not automatically. Convection usually tastes cleaner and won't scorch your herb, but it costs more and a lot of convection vapes only make vapour while you're drawing. Conduction is cheaper, heats faster and is easier to live with. Better depends on what you want out of a session.
Which one is more efficient with herb?
Convection tends to draw more out of a smaller load because the hot air works through the whole bowl evenly. Conduction can be efficient too if you pack tight and stir, but lazy packing leaves the middle under-cooked while the edges roast. Pure convection is usually the winner per gram.
Does conduction or convection taste better?
Convection, generally. Because nothing sits on a hot wall, the first few draws come through clean and bright instead of toasty. Conduction can taste great early too, it just tips into a roasted, popcorn flavour sooner.
What is a hybrid vaporizer?
One that heats with both methods at once, a warm chamber wall plus hot air pulled through the bowl. The Mighty and the Volcano Hybrid work this way. You get the steady, on-demand feel of conduction with a good chunk of convection's even extraction and flavour.
Why does my conduction vape scorch the herb?
Because herb is resting against a hot surface and not moving. Set a lower temperature, pack a touch looser, and give it a stir halfway through. A finer, even grind helps too, big chunks cook unevenly and the bits touching the wall darken first.
Are most portable vaporizers conduction or convection?
Most pocket portables are conduction or hybrid, because true convection is harder to do well on battery power. Full-convection portables exist, the Firefly 2+ and the TinyMight are two, but they ask more of the battery and more of your technique.
Do convection vaporizers waste battery?
They work the battery harder, yes. Heating air on demand draws a lot of current, so on-demand convection portables tend to get fewer minutes per charge than a conduction vape that holds one steady temperature. Removable batteries make that a non-issue if you carry a spare.
What temperature should I use for each?
Same broad range either way, roughly 180-190°C for flavour, 190-205°C for balance, 205-220°C for big clouds. The catch is conduction often reads a few degrees hotter at the herb than the screen says, so if you're getting a scorched taste, drop it 5-10°C.
Is session or on-demand the same as conduction vs convection?
They overlap but they're not the same thing. Session means the vape heats a bowl for a set few minutes; on-demand means it heats only while you draw. Most conduction vapes are session-style, most pure-convection portables are on-demand, but there are hybrids that blur the line.
Which is easier for a beginner?
Conduction or a hybrid. You load it, hit the button, wait for the buzz and draw, not much can go wrong. On-demand convection rewards a slower, more deliberate pull and takes a week or two to get the feel for. Great once it clicks, just a steeper start.
Does heating style change how I draw?
It does. Conduction is forgiving, pull how you like. On-demand convection wants a long, slow draw so the air has time to heat as it passes through; rip it fast and you'll get thin, cool vapour. Match your draw to the vape and both get better.
Can one vape do both conduction and convection?
That's exactly what a hybrid is, and it's why devices like the Mighty draw so smoothly. Some otherwise-conduction vapes also add a bit of convection as air moves through the bowl, so the line in real life is blurrier than the textbook split suggests.
Why are convection vaporizers more expensive?
Heating a steady stream of air to a precise temperature, fast, takes better engineering than warming a metal chamber. More power management, tighter tolerances, usually a glass or steel vapour path. You're paying for the harder job, and in the desktops it shows.
