When selecting a gas stove, the primary consideration is the heat output (BTU/kW) and material durability. For residential use, focus on aesthetic integration and safety features like Flame Failure Devices (FFD). For commercial settings, prioritize high-grade SUS304 stainless steel bodies, heavy-duty cast iron burners, and high-efficiency combustion systems that can withstand 12+ hours of daily operation. Ensure the stove is compatible with the local gas type, whether LPG (Liquefied Petroleum Gas) or NG (Natural Gas), as orifice sizes differ.
