In the convection vaporizers mechanism of forced air is applied to generate the vapors. In these vaporizers, the hot air is blown through the herbs or heating element, and from that user can easily inhale the air either with the aid of a pump or a fan.

Most of the vaporizers which are present in the market are based on the principle of the convection heating. These vaporizers include the wood box vaporizers. All the high class vaporizers in the present market are the convection vaporizers.

In the radiating vaporizers the process of radiation heating is done. In this process, the substance which has to be vaporized is subjected to the direct and bright light. The temperature of the substance gets raised as it absorbs the radiant energy of the light source. The main thing about the radiation vaporizers is that they are generated in very rare quantity but their performance is double as compared to the convection vaporizers. In radiation vaporizers, a magnifying glass and a pipe can be effectively used on a sunny day. But for this a lot of practice and care is required to generate the adequate amount of vapors.
