Thermal solar systems and components. Custom built systems. Performance test methods for solar water heater stores | Status: Superseded, Withdrawn

1 Scope 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 hot water systems. However, the thermal performance of all other thermal stores with water as a storage medium can also be assessed according to the test methods specified in this document. The document applies to stores with a nominal volume between 50 l and 3 000 l. This document does not apply to combistores. Performance test methods for solar combistores are specified in EN 12977‑4.
