EPG
In the EPG calculation a
distinction is made between individual systems and collective systems. This
distinction is made to determine the flat rate efficiency of boilers and the
auxiliary energy for heating. In the case of domestic hot water, systems
including circulation pipes and hot water reservoirs are considered to be
collective systems. The same holds for systems including block heating in which
heat is transferred into the hot domestic water through a heat
exchanger.
EPG
In case of individual
systems, both the flat rate and detailed method can be chosen to calculation the
auxiliary energy for heating.
•Flat rate: The auxiliary energy for individual systems is determined using the flat rate method.
•Detailed: The auxiliary energy for individual systems is determined according to quality statements. A sub-screen 'Auxiliary energy heating' appears for the generators in which the auxiliary energy can be specified in multiple ways.
