"冬天衣服难干，搭在暖气上一晚上就烘透了，还能给屋里加湿，多划算……"这条网友的建议，在 天津大学建筑设计规划研究总院有限公司热力室副主任冯卫星看来是得不偿失。 "这样做会严重降低取暖效率，直接导致能源浪费。"冯卫星解释，暖气片的工作原理是通过金属散 热面与室内空气进行热交换，以对流（热空气上升、冷空气补充）和辐射（直接向周围空间释放热量） 两种方式提升室温。当湿衣物覆盖在暖气片上时，相当于给散热面加了一层隔热屏障：一方面阻挡热量 向室内散发，另一方面衣物中的水分蒸发会消耗大量热能。这部分热能并未用于提升室温，而是以蒸发 潜热的形式被白白损耗。 从卫生角度来看，暖气片更不是安全的衣物烘干载体。湿衣物覆盖在温暖的散热面上，会形成高湿 的微环境。这种环境是大肠杆菌、黑曲霉等细菌和霉菌滋生的"温床"。 同时，暖气片在日常使用中，表面易吸附空气中的灰尘、螨虫排泄物等污染物。当衣物水分蒸发 时，水蒸气会将这些细菌和污染物一同带入室内空气；部分细菌和污染物还会重新附着在衣物表面。对 于过敏体质者、老人、儿童等敏感人群而言，这些物质可能引发皮肤瘙痒、过敏性鼻炎，甚至导致呼吸 道不适等健康问题。 根据《室内空气质量标准》（G ...

Core Points - The article emphasizes the importance of safely using gas wall-mounted boilers, especially as temperatures drop, highlighting potential safety hazards associated with improper use [1][2]. Group 1: Safety Risks - Inadequate combustion of gas can produce carbon monoxide, a toxic gas that poses serious health risks if not properly vented [2]. - Carbon monoxide is described as an "invisible killer," being colorless and odorless, making it difficult to detect [2]. Group 2: Prevention Measures - Proper installation of a dedicated flue that extends outdoors is crucial to prevent gas leaks [3]. - Regular checks of the flue for damage, blockages, and secure fittings are necessary to ensure safe operation [3]. Group 3: Pre-Usage Checks - Before starting the boiler, it is essential to check for gas leaks using soapy water on connections, ensuring no bubbles appear [5]. - The pressure gauge should read between 1 bar and 1.5 bar; adjustments may be needed if the pressure is too low or too high [5][6]. Group 4: Usage Guidelines - Users should maintain power to the boiler during the heating season, even when the house is unoccupied, to prevent pipe freezing [8]. - Good ventilation in the room where the boiler is installed is critical, and it should not be placed in bathrooms or sealed spaces [9]. Group 5: Emergency Procedures - In case of suspected gas leaks, immediate actions include shutting off the gas supply and avoiding any electrical devices or open flames [14]. - If the boiler malfunctions, users should consult the manual for error codes and refrain from self-repair, contacting professionals instead [14]. Group 6: Maintenance Recommendations - Regular maintenance every 1-2 years is advised to clean components and check operational efficiency, which can enhance safety and reduce gas costs [16][17].

Group 1 - The company appointed Mr. Lu Chupeng as a non-independent director on September 18 [1] - The board of directors and senior management of the company consists of 9 members, excluding independent directors and supervisors [1] - Mr. Lu Chupeng has held various positions within the company since 2006, including chairman of the supervisory board and vice president [1] Group 2 - The company, founded in August 1993, specializes in the research, production, and sales of gas water heaters, gas stoves, and gas wall-hung boilers [3] - The company has expanded into the new energy water heating system sector and has become a leading enterprise in the domestic gas appliance industry [3] - According to the financial report for the first half of 2025, the company achieved a revenue of 4.083 billion yuan, a year-on-year increase of 7.14%, and a net profit attributable to shareholders of 379 million yuan, up 6.68% year-on-year [3]
