scope:

This European Standard specifies methods for testing and reporting of the rating and it specifies requirements for marking of air/water, brine/water, water/water and direct exchange/water heat pumps with electrically driven compressors connected to or including a domestic hot water storage tank. When these units are used for space heating, then EN 14511 (all parts) applies. In case of air-to-water heat pumps, this European Standard comprises only factory-made units which can be ducted on the airside. This European Standard comprises only the testing procedure for the domestic hot water production of the heat pump system. NOTE - 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. In the case of units consisting of several parts, the standard applies only to those designed and supplied as a complete package. This European Standard does not include any requirement about the quality of water.
