24小时恒温工作意味着壶体长期处于加热保温状态，必须确认具备双重防干烧+超温断电保护，且底盘发热管与水体分离设计；无防干烧保护的恒温壶空烧存在起火风险

Unverified'恒温壶'与'保温壶'是两回事：恒温壶需持续通电主动加热维持温度，纯保温壶靠真空层被动保温6-8小时但温度只降不升，长途出行无电源场景反而保温壶更实用75% similarUnverified复底锅长期空烧或骤冷（热锅立即冲冷水）可能导致复底层脱层鼓包，不锈钢锅避免空烧和急速温差是保证使用寿命的关键75% similarUnverified焖烧杯的保温本质是真空隔热，与容器壁厚无关；市面标称'12小时保温'多指静置温度，实际焖煮时开盖投料会损失热量，选购看实测'6小时保温后温度'比看总时长标称更可靠74% similarUnverified保温性能取决于外壳材质与密封性：金属外壳+良好密封的机型断电后可保温1-2小时，日常炖煮省电。若锅盖与内胆间隙大、蒸汽外泄明显，说明保温设计差、能耗高且汤汁易熬干74% similarUnverified钢化玻璃锅盖若无透气孔，长时间高温使用可能因内压过大炸裂，选购带蒸汽孔的锅盖更安全；同时避免涂层锅空锅预热超过1分钟73% similar
