Variant menu: Calculations > Assistant > Define Requirements > Hot Water or > Heating

Here, there are 2 pages to fill out: consumption of hot water and heating.

There are 2 possibilities for entering hot water requirements: if you know the average daily requirement, you can enter it directly by clicking on the checkbox. If you do not know it, you can enter the probable or actual number of people to be supplied. This figure is then used to calculate the absolute requirement with a predefined specific requirement. The specific requirement per person can be entered and modified in the main menu under Options > Design Assistant.

The DHW target temperature and cold water temperature should be entered here and can also be preset under Options.

Click on the Heating tab to access the input page for heating energy requirements.

Here, too, you can either enter the heating energy requirement (e.g. calculated in accordance with DIN 4701) or, as this value is frequently not known, have this value calculated by internal characteristic values by entering the thermal standard of the building.

To determine the annual heating energy requirement, calculated for every hour of the year by T*SOL, entry of the standard outdoor temperature is required.
