EN 12977-4

EN 12977-4 Thermal solar systems and components - Custom built systems - Part 4: Performance test methods for solar combistores - This European Standard specifies test methods for the performance characterization of stores which are intended for use in small custom built systems as specified in EN 12977-1. Stores tested according to this document are commonly used in solar combisystems. However, the thermal performance of all other thermal stores with water as a storage medium (e.g. for heat pump systems) can be also assessed according to the test methods specified in this document. This document applies to combistores with a nominal volume up to 3 000 l and without integrated burner. NOTE This document is extensively based on references to EN 12977-3:2012.
