Conduction vs Convection

Vaporization is a process in which hot air is passed through a material, or heat is applied directly to the surface of it. This process releases the active ingredients and essences of the material without combustion (which tends to create particulates and other harmful toxins). Vaporization, or volatilization, is sometimes referred to as “aromatherapy”. In comparison to other delivery methods, vaporization has a more rapid onset with greater efficiency in dosages. Clinical studies have proven that vaporization is the clean alternative for those worried about inhaling unwanted carcinogens. Generally speaking, there are 2 types of vaporization styles available to the consumer today.
Conduction is considered the more primitive vaporization technique in which heat is applied to the surface of a material below the point of combustion. There is less room for error with this style of vaporization, and sometimes combustion can occur. Convection is the most popular vaporizer style on the market. Hot air is essentially forced through a material creating a phase change that converts solid materials into a gas (or water vapor, in this case). The taste, efficiency, and ease of use are second-to-none when using a convection-style vaporizer. There are 2 different approaches to convection vaporization: forced air and passive draw.

Conduction Vaporizers
  • Reasonably priced
  • Simple to operate
  • Durable
  • More difficult for novice users
  • Unstable temperature control

Convection Vaporizers 
  • Efficient
  • More control over temperature and draw
  • “Vapors on demand”
  • Draw depends on the user (besides forced air)
  • Cost
