Heat management device, or HMD for short, are here today to help us manage the heat on the hookah bowl so the shisha can burn evenly. They help regulate the heat and you can adjust the temperature manually to make sure that the tobacco is not burning too fast or slow. Adjusting the device can produce a lot of smoke at the expense of the longevity of the session, or you can set it to where there will be less smoke but the hookah may last up to 3 hours or more. We can help you select your heat management device and guide you on how to use it as well as compatibility with certain tobacco and bowls. As always, we provide lots of reviews, pictures, galleries, and videos so you can research yourself and make a sound decision when purchasing a hookah heat management device.
