This Prestandard specifies test methods for the performance characterization of stores which are intended for use in small custom built systems as specified in ENV 12977-1.
Stores tested according to this Prestandard are commonly used in solar hot water systems.However,also the thermal performance of all other themal stores with water as soorage medium(e.g. for heat pump systems)can be assessed according to this Prestandard.
The Prestandard applies to stores with a nominal volume between 50 and 3000 litres and without integrated oil or gas bumer.
