摘要： Thermal water storage system (10), characterised in that it comprises:
- a container (11) configured as a vertical tank, comprising:
- a curvilinear side wall (11.1), formed by means of curved sheet metal, and
- a flat panel (11.2), sealingly fixed along two opposite vertical edges of said curvilinear side wall (11.1) and having openings (11.3) for the insertion of heat exchangers;
- two opposite covers (13.1, 13.2), which sealingly close the top and bottom, respectively, of said tank (11);

- heat exchangers (12) arranged at least partly, by means of a respective coil heat exchange body (12.1), inside said tank (11), fixed, by means of respective end connections (12.2), with respect to said panel (11.2) at said openings (11.3), and provided for the circulation of a carrier fluid through the respective coil body (11.2);
and in that said openings (11.3) are configured as slots, having a larger dimension in the height direction of the tank (11), and said heat exchangers (12) comprise the respective flat body (12.1),
wherein the largest dimension in width of the flat body (12.1) of each of said exchangers (12) is smaller with respect to the largest dimension in height of the corresponding slot (11.3) and is less than the maximum width, according to a horizontal plane, of the interior of the tank (11) at the level of the corresponding slot opening (11.3).
According to the invention, said heat exchangers (12) are arranged in said tank (11) according to two different arrangements:
- a first introduction arrangement of the respective flat body (12.1) into the tank (11) through the corresponding slot (11.3), wherein the respective flat body (12.1) is arranged orthogonal with respect to a horizontal plane, and
- a second operating arrangement of the respective flat body (12.1) in the tank (11), wherein the respective flat body (12.1) is arranged inclined with respect to a horizontal plane according to an angle comprised between ± 90° and 0°.

摘要： Control of an electric water heater based on a two-mass model may be provided. First, a reserve capacity of an Electric Water Heater (EWH) may be determined. Next, a safe deferred time for the EWH based on the determined reserve capacity may be determined. Then a grid service event initiation may be received. In response to receiving the grid service event initiation, the EWH may be caused to not heat water for the determined safe deferred time.
