European foreword
This document (prEN 15316-5:2022) has been prepared by Technical Committee CEN/TC 228 “Heating
systems and water based cooling systems in buildings”, the secretariat of which is held by DIN.
This document will supersede EN 15316-5:2017.
The main changes compared to EN 15316-5:2017 are:
1) inclusion of simultaneous heating of the storage;
2) inclusion of arbitrary layer volume selection;
3) inclusion of additional heat losses due to the thermosyphon circulation;
4) calculation procedure for method A and B have been reviewed and several changes implemented;
5) Annex A contains a template for the data and parameters used in the standards and Annex B a set of
default values. Default values given in Annex B may be overridden by a national annex;
6) the previous Annex C and Annex D have been withdrawn;
7) inclusion of matrix approach for solving the re-arranging of the layer temperatures in method A
