Recently, news of a ‘southern tourist opening a window for a day and freezing a northern underfloor heating system’ sparked widespread discussion. The incident occurred at a homestay in a northeastern Chinese city, where a visitor from southern China, unaccustomed to the intense indoor heat, left the window open for an extended period to cool down the room. This caused a sharp drop in indoor temperature, triggering the heating system’s low-temperature safety shutdown. The water in the pipes cooled so drastically that parts of the system froze, resulting in equipment damage.This case highlights the stark differences in winter heating practices and daily habits between northern and southern China. In the north, centralized heating systems—especially underfloor heating—rely on consistent high-temperature water circulation. Prolonged exposure to cold air can not only reduce comfort but also cause irreversible damage. In contrast, most southern regions lack centralized heating, and residents commonly regulate indoor temperatures by opening windows, often unaware of how sensitive northern heating systems are to such actions.Experts advise against keeping windows open for long periods during winter, especially in extremely cold regions. If ventilation is needed, it should be brief and intermittent, with close attention to indoor temperature changes. Homestay hosts and platforms are also encouraged to provide clearer instructions to help southern guests adapt to northern heating environments and prevent similar incidents.
近日，一则‘南方游客开窗一天冻坏东北地暖’的新闻引发热议。事件发生在东北某城市的一处民宿，一名来自南方的游客因不习惯室内高温，入住后将窗户长时间敞开以降温。结果导致室内温度骤降，地暖系统因低温保护机制自动停机，管道内水温过低甚至出现局部冻结，最终造成地暖设备损坏。这一现象背后反映出南北方在冬季取暖方式和生活习惯上的显著差异。东北地区普遍采用集中供暖，地暖系统依赖持续稳定的高温热水循环，一旦室温长时间低于设定阈值，不仅影响舒适度，还可能对设备造成不可逆损伤。而南方多数地区无集中供暖，居民更习惯通过开窗通风调节室温，对地暖系统的运行原理缺乏了解。专家提醒，冬季使用地暖时应避免长时间开窗，尤其在严寒地区。如需通风，建议短时、分次进行，并注意观察室内温度变化。同时，房东或民宿平台也应加强入住说明，帮助南方游客适应北方供暖环境，避免类似事故再次发生。
