Only ALFA has Heat Genius, a trifecta of technologies that allow you to consistently bake perfect pizza at home.
1 - Authentic HeatKeeper Firebrick vs ordinary lava stone or ceramic Alfa uses an authentic firebrick in every pizza oven they make. This HeatKeeper firebrick, which they make in their factory in Rome, Italy, the home of pizza, absorbs and stores heat far better than the lava stone or ceramic used in other pizza ovens. This is crucial to baking a crispy, moist crust at precisely the right temperature, quickly and without burning.
2 - DoubleDown Ceramic Superwool ® Insulation vs ordinary rock wool insulation (or no insulation at all) The space between the two stainless steel walls on an Alfa Pizza Oven is filled with DoubleDown Superwool® insulation. This European ceramic fiber offers up to twice the heat resistance of the rock wool insulation used in other artisan at-home pizza ovens, which maintains the heat and allows you to consistently bake perfect pizzas. It also allows for faster heat recovery between pizzas and dramatically lowers the temperature of the outer oven wall.
3- Patented Full Effect Full Circulation Flue System ® vs ordinary “up and out” chimneys Other pizza ovens exhaust precious heat out the chimney at the top of their oven. Up and out! Not Alfa. The chimney may be at the top, but, thanks to the patented Full Effect Full Circulation Flue System®, hot air circulates fully around the chamber and is driven back down to where it can heat the firebrick and pizza. This is key, as it ensures the proper temperatures required to bake both crust and toppings. The circulating heat then hits a deflector at the top of the oven and travels up an escape where it finally exits out the chimney. Around and down. Then up and out. Clever!
