本欧洲标准规定了测试，性能评估和空气/水，盐水/水，水/水和直接交换/水热泵热水器和热泵组合式加热器与电动压缩机和连接的热水能效的计算方法到或包括家用热水储水箱进行家庭热水生产。 本欧洲标准仅包括热泵系统的家用热水生产的测试程序。 注1:本标准未对国内热水生产和空间采暖同时运行的试验程序进行处理。同时意味着家用热水生产和空间供热同时发生并可能相互作用。 注2:对于热泵组合加热器，空间加热的季节效率根据EN 14825确定。 本欧洲标准仅适用于在热泵和储罐包装中供应的热水器。在由几个制冷剂连接部分组成的热水器的情况下，本欧洲标准仅适用于作为完整包装设计和供应的那些。 本欧洲标准没有规定废水质量的要求

This European Standard specifies methods for testing, rating of performance and calculation of water heating energy efficiency of air/water, brine/water, water/water and direct exchange/water heat pump water heaters and heat pump combination heaters with electrically driven compressors and connected to or including a domestic hot water storage tank for domestic hot water production. This European Standard comprises only the testing procedure for the domestic hot water production of the heat pump system. NOTE 1 Testing procedures for simultaneous operation for domestic hot water production and space heating are not treated in this standard. Simultaneous means that domestic hot water production and space heating generation occur at the same time and may interact. NOTE 2 For heat pump combination heaters the seasonal efficiency of space heating is determined according to EN 14825. This European Standard only applies to water heaters which are supplied in a package of heat pump and storage tank. In the case of water heaters consisting of several parts with refrigerant connections, this European Standard applies only to those designed and supplied as a complete package. This European Standard does not specify requirements of the quality of the used water.
