Due to the large share of the residential building sector in CO emissions, it is necessary to look for quick-to-implement and cost-free solutions for heating systems aimed at increasing their efficiency and reducing fuel consumption. The aim of the study is a multi-aspect assessment of the proper setting of the heating curve in the weather controller of a low-temperature floor heating system with a condensing gas boiler, and an analysis of the impact of the heating curve slope on the natural gas consumption, the emission of gaseous and dust pollutants and on maintaining appropriate indoor air parameters: air temperature, operative temperature and and . A wide range of simulation tests were carried out using the TRNSYS software for an existing energy-efficient single-family residential building, with mechanical ventilation with heat recovery, located in north-eastern Poland in Bialystok. Changing the heating curve slope by 0.1 can reduce gas consumption and pollutant emissions by 1.6–10.3 %. Low heating curve slopes may result in failure to reach the temperature set by users (difference between the set and achieved indoor temperature up to 1.9 K), while maintaining standard thermal comfort parameters (−0.5

评估设置供暖曲线对减少住宅建筑燃气消耗同时确保热舒适度的影响
由于住宅建筑领域的二氧化碳排放量很大，因此有必要寻找快速实施且免费的供暖系统解决方案，以提高其效率并减少燃料消耗。本研究的目的是对带有冷凝式燃气锅炉的低温地暖系统的天气控制器中加热曲线的正确设置进行多方面评估，并分析加热曲线斜率对加热曲线的影响。天然气消耗、气态和粉尘污染物的排放以及维持适当的室内空气参数：空气温度、工作温度和 。使用 TRNSYS 软件对位于波兰东北部比亚韦斯托克的一栋现有节能单户住宅楼进行了广泛的模拟测试，该住宅楼配有热回收机械通风。加热曲线斜率每改变0.1，可减少燃气消耗和污染物排放1.6%~10.3%。较低的供暖曲线斜率可能会导致无法达到用户设定的温度（设定温度与实现的室内温度之间的差异高达 1.9 K），同时保持标准热舒适参数（−0.5
