The thermal stores in Hysopt can be used for central heating (CH) or domestic hot water (DHW).
Central heating storage units
The central heating storage units can be divided into three types: Direct, Indirect, and Electrical.
...
The first one is a thermal store in the return pipe, which is only used in specific circumstances (mostly used for cooling but on rare occasions also for heating). The second one is a thermal store with multiple temperature measurements. This BC is mostly used as a simplified thermal store representing multiple thermal stores in series, where for instance 1 thermal store has 3 temperature measurement points, the second thermal store only 2 points, and so forth. The multiple measure points are often used in large hybrid systems where the priority of each type of production unit is decided in the controls and the applied measure points.
Design parameters
The parameters needed for the design of the system are mostly the design heat flow and the temperature regime.

If the actual KV value isn't known, the user can click on the "pencil" icon which results in a calculation popup window. In the popup window, the user can calculate the KV value by entering the pressure drop and flow rate (and if needed, the brine, mixture, and reference temperature). This option is preferred when the information on the boiler is known. However, the user can also let the software automatically calculate the KV value depending on the design flow rate by using the other tab and entering the estimated pressure drop over the boiler.

Simulation parameters
The parameters needed for simulation are the following:
