On the Heat Exchanger / Tank page, the internal tank for the supply of hot water volume is defined.
The geometry of the internal tank is displayed only and cannot be changed.
Solar Fraction of Systems using Combination Tanks
For combination tank systems, the fraction (domestic hot water) and the heating fraction are determined in the dynamic simulation and displayed individually in the project report (previously: total solar fraction), as the fraction for funding applications must be separately given.
In every time increment, the T*SOL simulation balances if the yields contribute to the fraction of domestic hot water and thermal heat supply, the circulation losses, and the tank losses or the heating of the storage tank content. Thus, the origin (solar loop or supplementary heating) of the heat is known, meaning heat delivery can be distributed.
