12. Following this, the key results are displayed as a graph and table in monthly resolution. The
energy requirement of the solar pump in the collector loop is also stated here.
13. Click on the symbol , to view further simulation results, heating energy yields, the solar yield,
and the solar fraction.
If the heating energy yields used in the simulation significantly differ (> 5%) from the defaults, a
warning is shown.

8.3.1 Heating requirement details
EnEV > Heating Energy Requirement
The heating output is required for the calculations. This can either be entered directly or calculated from
the net energy with the help of distribution and transfer losses.
As only residential buildings are considered, the following implicit assumptions are made:
• With night switch-off
• Operation from 6.00 am to 11.00 pm, i.e. 17 hours (DIN V 18599-10, table 3)
• Continuous operation at weekends due to being residential building (DIN V 18599-5, chapter
5.4.1)
Transfer losses are calculated in accordance with DIN V 18599-5, chapter 6.1, the distribution losses in
accordance with chapter 6.2. For this, the characteristic length and width of the building is required.
In order to calculate transfer and distribution losses, further information on the type and design of the
heating equipment must be entered. A distinction can be made between radiators and heating
surfaces (DIN V 18599-5, table 7).
The following settings are available for radiators:
• Temperature control
o Unregulated, with central flow temperature control
