In former times, there was no notion of heat management devices. However, as hookah smoking increased, accessories related to hookah also increased. Heat management devices are one of those accessories. Heat management devices increase the output of heat, extend the lifespan of coal, and generally simplify the overall process.
Heat management systems cannot save the session if the tinfoil and charcoal are unbalanced. Suppose you are using a heat management system, the ratio of tinfoil to coal changes.
A new hookah, tobacco, or charcoal can help you discover your perfect balance with your hookah.
