本欧洲标准适用于生产家用热水的燃气电器。适用于连接或包含家用热水储水箱的吸附热泵。它适用于作为单一单位销售的包装或完全指定的包装: - 用于热泵的单个气体燃烧器和/或用于峰值负载设备的附加气体燃烧器; - 不超过70kW的气体热输入; - 一个不超过500升的热水储罐。 EN 13203-1在定性和定量方面列出了为选定的各种用途提供家用热水的性能。它还给出了一种向用户呈现信息的系统。 本文件提出了一种评估电器能量性能的方法。它定义了每个家庭热水用途，厨房，淋浴，浴缸以及这些的组合的每日自来水循环数量，以及相应的测试程序，使不同燃气器具的能源性能得到比较和匹配的用户。 在夏季模式下，吸附热泵循环不能用于家庭热水生产时，本标准不适用于能源性能评估，必须使用EN 13203-2

This European Standard is applicable to gas-fired appliances producing domestic hot water. It applies to sorption heat pumps connected to or including a domestic hot water storage tank. It applies to a package marketed as single unit or fully specified that have: - a heat input not exceeding 400 kW; and - a hot water storage tank capacity (if any) not exceeding 2000 l. In the case of combination boilers, with or without storage tank, domestic hot water production is integrated or coupled, the whole being marketed as a single unit. EN 13203 1 sets out in qualitative and quantitative terms the performance in delivery of domestic hot water for a selected variety of uses. It also gives a system for presenting the information to the user. The present document sets out a method for assessing the energy performance of the appliances. It defines a number of daily load profiles for each domestic hot water use, kitchen, shower, bath and a combination of these, together with corresponding test procedures, enabling the energy performances of different gas-fired appliances to be compared and matched to the needs of the user. Where other technologies are combined with a gas-fired boiler or a water heater to produce domestic hot water, specific parts of EN 13203 apply. Horizontal ground heat sources are not covered by the scope of the present European Standard.
