Which is better, the energy-gathering furnace or the open-air furnace?

The energy gathering furnace is good. The energy-gathering furnace adopts brushed stainless steel panel, which is stretched into a whole. Compared with ordinary cookers before, the smooth lines of energy-gathering cookers are like fashionable works of art in the kitchen, and they are also a versatile product for another day. The energy-gathering furnace is a newly patented "energy-gathering ring" burner, with nearly ten thousand fire holes evenly distributed on its surface, and its burning area is 100 times that of ordinary stoves. At the high temperature of 860 degrees Celsius, high-energy light waves equivalent to 60% of gas efficiency can be excited, which forms double heating with the flame.
