Abstract: The present inventions is directed to a sensible heat storage apparatus and use thereof. The apparatus comprises an inner vessel (2) comprising an internal volume (3) adapted to comprise a fluid (4); an outer container (5) enclosing said inner vessel; a thermal insulation layer (6) between said inner vessel and said outer container; and at least two integrated connections (71, 72) to connect the internal volume of said inner vessel to an outer environment through the thermal insulation layer. Said integrated connections are adapted to integrate and accommodate at least two individual sub-connections such that every integrated connection forms a single thermal bridge (8) between the inner vessel and outer container and wherein all thermal bridges are located in the bottom 75% of the total height of said outer container.

Abstract: A double-wall insulated container has an internal wall and an external wall enclosing an intermediate space which is under partial vacuum. A foam glass granulate fills the intermediate space and supports the walls. The walls may be metal or plastic and sealed with a vapor barrier as necessary to make the space leak-proof. The container may be styled as a Dewar flask for food or beverages, or larger to make it suitable for a household appliance such as a refrigerator.
