Conduction: n. the process by which heat or electricity is directly transmitted through a solid substance
Convection: n. the process by which heat is transmitted through a liquid or gas
The whole point of vaping is to enjoy your substances without the harmful side of effects of burning them, which is known as “combustion.” Vaporization occurs by heating your substance sufficiently to release its active compounds, but not so much that the substance burns. The sweet spot for efficient vaporization is between 350° and 450°. Less than 350° is too cool to produce vapor, and temperatures higher than 450° will simply burn your substances—in which case you might as well smoke a cigarette.
There are 2 methods of vaporization—conduction or convection. With conduction, the heating element ‘conducts’ energy from the battery and turns it into heat, which is directly applied to your vaping substance. Conduction heating is relatively easy to accomplish—you probably do it every day in some form: holding a butane torch to a glass bowl? Conduction. Bacon and eggs in a skillet? Conduction. Hot dogs roasting in a bonfire? Conduction, and now we’re hungry. Because conduction is simpler, this method allows for less complicated vaporizer designs that generally come with a lower price tag. However, there are some caveats: There’s a higher risk of combustion, especially if your vaporizer doesn’t have precise temperature control, and if you’re vaping dried herbs, you’ll have to stir or shake them occasionally to ensure even heating throughout.
Convection vaporizers heat the air around your substances. The substance itself never touches the heating element, rather, it is contained in a chamber while heated air is passed through. Just like conduction, you’re familiar with convection in everyday situations: Using a hair dryer? Convection. Baking a cake? Pretty much convection. Cup o’ Noodles in a microwave? Yes, convection, and we should really get something to eat…
Convection vaporizers are more complex and tend to be a little-to-a-lot pricier than conduction models. Since they allow for more precise temperature control, they take somewhat longer to heat up. But, more accurate temperature control is big selling point: there’s less of a risk of combustion, and more even heating of your substances.
Well, there ya have it—conduction vs. convection. As with any type of vaporizer, take your time to figure out what’s most important to you and what combination of features will best meet your needs—in any case, GetMaryJ has you covered!
