EPG
This box indicates
whether a circulation system is present in the building or part of the building.
A circulation system can be specified only if the generation configuration is a
collective system, which should be specified in the generation configuration for
domestic hot water. The losses of the circulation system will be captured in the
distribution efficiency, whereas the other energy losses are included in the
emission efficiency, e.g. the losses in the pipes to the taps.
EPG
This box indicates
whether the circulation system in the building or part of the building is
permanently in operation. If this is not the case, additional heat losses due to
cooling are charged which are included in the distribution efficiency. By
unchecking this box, an additional input field appears in which the percentage
of time for which the circulation system is in operation can be indicated.
Whether or not the circulation system is in permanent operation does not affect
the calculations in case the flat rate method is applied to compute the
distribution efficiency, see Pipe data.
[%] EPG
The percentage of the day for which the circulation
system is in operation can be indicated here if this system is not in permanent
operation. This value does not affect the calculation results in case the flat
rate method is applied to compute the distribution efficiency, see Pipe
data.
EPG
If the power of the
circulators is known this should be specified here by checking the box; an
additional input field then appears in which the power of the circulator can be
expressed in W. Currently, it is required to specify the power of the pumps as
the alternate method is not supported yet.
