Sensible heat device

A sensible heat storage system comprising a sensible heat storage device, comprising:

• a thermally insulated tank comprising an interior reservoir for holding a fluid therewithin;
• a first in- and outlet that enables a fluid connection between the interior reservoir of the thermally insulated tank and an environment outside said thermally insulated tank;
• wherein said first in-and outlet is arranged in a lower section of the thermally insulated tank and debouches in a lower portion of the interior reservoir;
• a second in- and outlet that enables a fluid connection between the interior reservoir of the thermally insulated tank and an environment outside said thermally insulated tank;
• wherein said second in-and outlet is arranged in a lower section of the thermally insulated tank and debouches in an upper portion of the interior reservoir;
• wherein said second in-and outlet comprises an interior tube that extends upwardly through the interior reservoir from the lower section of the thermally insulated tank to the upper portion of the interior reservoir in which it debouches, wherein the sensible heat storage system further comprises
• a heat storage charging unit comprising a heat source, being preferably a flow through heater wherein the heat storage charging unit is arranged for circulating heat storage fluid held in the sensible heat storage device from the first in-and outlet of the sensible heat storage device through the heat source for heating the heat storage fluid and to the second in- and outlet for inserting the heated heat storage fluid into the sensible heat storage device;
• a heat storage discharging unit wherein said heat storage discharging unit comprises a flow through heat exchanger that is arranged to be coupled to a heat consuming system, such as a hot water and/or heating system of a building, and is arranged for transferring heat from a heat storage fluid to the heat consuming system;
• wherein the heat storage discharging unit is arranged for circulating heat storage fluid held in the sensible heat storage device through the second in-and outlet of the sensible heat storage device through the flow through the heat exchanger and through the first in-and outlet for inserting the heat storage fluid into the sensible heat storage device
