摘要： It is described a system (100) for storing heat. The system (100) comprises a first housing section (110) with a first storage volume (V1), wherein the first housing comprises a first opening (113) for connecting the first storage volume (V1) to an environment. A first type (111) of first heat storing elements is arranged within the first housing section (110). The system further comprises a second housing section (120) with a second storage volume (V2), wherein the second housing section (120) comprises a second opening (123) for connecting the second storage volume (V2) to the environment, wherein the first storage volume (V1) and the second storage volume (V2) are interconnected for forming a common storage volume. A second type (121) of second heat storing elements is arranged within the second housing section (120). The first heat storing elements of the first type (111) comprise a respective first element size, wherein the second storing elements of the second type (121) comprise a respective second element size. The first element size differs from the second element size.
