The quartz tube inside this outdoor heater offers many advantages versus glass tube. More purity, heat efficiency and resistance to sudden temperatures changes. And while it doesn’t rain much in Dubai (nor you should basically use under rain), If by any chance some water drops hits a hot glass tube, there is a good chance It would crack. While quartz tubes offer much more durability.

Also we advice using powder coated heater instead of stainless in extreme humid places, like near beaches.
