Choosing a dry herb vaporizer often comes down to one decision that gets overlooked: how the device actually heats your material. Conduction, convection and hybrid systems each produce a noticeably different session, from heat up speed to flavour and vapour density. This guide breaks down how each method works, where it falls short, and which one fits your habits, updated for the new lineup.
How Vaporizer Heating Actually Works
Every dry herb vaporizer heats material below combustion temperature, which avoids producing smoke. How that heat reaches the herb, however, varies a great deal between devices, and it is the single biggest factor behind why two vaporizers at a similar price point can feel completely different in use.
There are three heating approaches on the market: conduction, convection and hybrid. Conduction heats the herb through direct contact with a hot surface. Convection heats the herb using a stream of hot air. Hybrid combines both. None of these methods is universally better; each suits a different type of session, and understanding the trade offs helps you avoid buying a device that fights against how you actually vape.
Conduction Heating Explained
How Conduction Heating Works
Conduction works much like a frying pan. The herb sits directly against a heated ceramic or metal chamber wall, and heat transfers straight into the material on contact. It is a simple, well established mechanism that has powered portable vaporizers for years, and it remains one of the most common methods in the dry herb vaporizer collection.
Where Conduction Performs Well
Because the herb is in direct contact with the heat source, conduction devices tend to heat up quickly and draw comparatively little power. In our testing, this generally translates to compact devices with fast readiness, which suits short, focused sessions rather than long lounging ones. If you want to load a bowl, get through it, and move on, conduction is a practical starting point.
The Trade Offs With Conduction
The main drawback of a hot surface approach is uneven extraction. Herb touching the chamber wall heats faster than herb sitting in the centre, so without a fine, even grind or the occasional stir, you can end up with darker material at the edges and undercooked material in the middle. Leaving a bowl half finished for too long can also produce a stale, over toasted taste, since the chamber keeps radiating heat even between draws.
Conduction Vaporizers Worth Considering
The XMAX Starry is a straightforward, budget conscious conduction device that suits newer users well, and it sits comfortably within our vaporizers under £100 collection. For something with a bit more refinement, the Arizer Solo 2 Max uses a conduction led design that has been tuned to reduce the harshness typically associated with pure hot plate heating.
Convection Heating Explained
How Convection Heating Works
Convection heating works on the same principle as a convection oven. Rather than touching the herb to a hot surface, the device draws fresh air across a heating element, and that hot air passes through the material to extract vapour. Nothing in the chamber is directly cooked; the herb is warmed by moving air rather than surface contact.
Where Convection Performs Well
Because heat is only applied to the herb while air is moving through it, convection devices tend to preserve flavour clarity for longer through a bowl. In our experience, this also suits microdosing well, since the material is not being slowly cooked while the device sits idle between hits. You can take a single draw and come back to the same bowl later without the leftover herb degrading in the way it can in a conduction chamber.
The Trade Offs With Convection
Maintaining a constant stream of hot air takes more energy than heating a static chamber wall, so convection devices generally draw more battery and often carry a higher price tag as a result. Many also reward a slower, more deliberate draw technique. Pull too quickly and you can undercook the herb; pull too slowly and sessions take longer than they need to.
Convection Vaporizers Worth Considering
The Arizer Solo 3 pairs a strong convection heater with a chamber that is genuinely easy to clean, making it a practical choice for regular use. Stepping up in power, the Tinymight 2 is a convection device built for rapid, on demand heating and dense vapour output. If you prefer a stationary session at home rather than something pocketable, our desktop vaporizer collection includes convection led models designed specifically for that use case.
Hybrid Heating Explained
How Hybrid Heating Works
Hybrid vaporizers combine both methods. The chamber walls provide a base layer of conductive heat, while an airflow system adds a convection boost during the draw. The result is a device that heats up faster than pure convection, while extracting more evenly than pure conduction.
Why Hybrid Suits Flagship Devices
Because hybrid systems borrow strengths from both approaches, they tend to be more forgiving to use than pure convection devices while producing a cleaner extraction than pure conduction ones. This versatility is why most flagship, higher price bracket vaporizers on the market use some form of hybrid heating.
Hybrid Vaporizers Worth Considering
The Venty is Storz and Bickel's current flagship portable and uses hybrid heating with adjustable airflow, letting you lean the experience towards denser or lighter vapour depending on preference. It sits within our wider Storz and Bickel collection, which has built its reputation on hybrid and convection heating over the past decade.
If you are deciding between two of their most talked about devices, our Frolic vs Venty comparison breaks down how the heating differences play out in day to day use.
Conduction vs Convection vs Hybrid at a Glance

| Best suited to | Quick, on the go sessions | Flavour focused, slower sessions | Users who want both |
Chamber Materials and Airflow: Why Build Quality Matters
The material used in the chamber and airpath affects the session as much as the heating method itself. Ceramic is a common choice for conduction chambers because it holds heat steadily, giving a consistent, if slower, extraction. Stainless steel is more common in convection and hybrid designs since it heats and cools quickly and is easy to keep clean over time.
In convection focused devices, borosilicate glass airpaths are widely used because the material is inert and does not add any metallic taste to the vapour. Whichever chamber material your device uses, a consistent, medium fine grind makes a measurable difference to extraction evenness.
A dedicated grinder from our grinder collection is a small upgrade that noticeably improves results across all three heating types.
Who Is This For?
Not every heating method suits every session style. Use the breakdown below to narrow down what actually fits how you vape.
- Commuters and discreet session users: Conduction devices such as the XMAX Starry or the entry level G Pen Dash 2 heat up quickly and suit short, focused sessions.
- Flavour focused users: If clarity of taste matters most, a convection device like the Arizer Solo 3 is a strong starting point.
- Power users who want it all: Hybrid devices like the Venty suit users who do not want to choose between speed and flavour.
- New or budget conscious buyers: Our vaporizers under £100 collection is a sensible place to start before committing to a premium hybrid device.
Choosing Your Heating Method
There is no single correct answer here, only the method that fits how you actually use a vaporizer. Conduction suits speed and simplicity, convection suits flavour and control, and hybrid suits anyone who wants a bit of both without major compromise.

Frequently Asked Questions
Is convection better than conduction?
Neither is better outright. Convection tends to hold flavour longer and extract more evenly, while conduction heats up faster and suits quicker sessions. Which one suits you depends on whether you prioritise speed or flavour clarity.
Do hybrid vaporizers cost more than conduction or convection only devices?
Generally yes. Hybrid devices combine more hardware, including both a heated chamber and an active airflow system, which typically puts them in a higher price bracket than simple conduction devices.
Why does my conduction vaporizer taste burnt near the end of a bowl?
This usually happens because the material closest to the chamber wall continues to heat between draws. Using a finer, more even grind and finishing a bowl in a reasonable timeframe helps reduce this effect.
Does grind size matter more for one heating method?
Grind consistency matters for all three, but conduction is the most sensitive, since uneven pieces heat at different rates against the chamber wall. Convection and hybrid devices are slightly more forgiving, though a good grinder still improves results across the board.
Can I use hybrid vaporizers for microdosing?
Yes. Most hybrid devices allow you to draw briefly and stop, similar to convection only devices, since the airflow component means the herb is not being constantly heated while idle.
