Unverified热负荷≥4.2kW的燃气灶才能实现快速爆炒，家用建议主灶眼≥4.0kW；小于3.5kW炒菜火力偏弱，仅适合煮汤炖菜90% similarUnverified燃气灶热负荷不是越大越好，家用炒菜4.0-4.5kW最实用；热效率一级标准台式≥63%、嵌入式≥59%，超过5.0kW的高火力灶反而因废气带走热量导致实际效率下降85% similarUnverified约3.5kW火力满足家用涮火锅和日常烹饪，但对爆炒类需要猛火的需求偏弱83% similarUnverified火力越大热负荷越高，但热效率往往下降——5.0kW以上的猛火灶热效率常低于4.0kW的常规灶，兼顾节能与火力选热负荷4.2-4.5kW+热效率65%以上的机型83% similarUnverified热功率越高越费气且对灶具散热要求越高，5.0kW以上大火力灶眼需搭配更大排烟量抽油烟机(≥18m³/min)，否则厨房温度骤升、燃烧不充分82% similar
