Remarks of Siemens
This section outlines how Siemens interprets the functions and processing functions according
to EN 15232-1:2017.
2
As a rule, DHW heating with storage tank is considered since considerable energy losses may arise
for improper solutions. Instantaneous water heaters close to the consumers are normally operated
based on demand and have limited automation functions.
2.2
1 A defined charging time can minimize the amount of time a higher generation temperature is
required for DHW charging.
2 In addition to 1) the storage will only be loaded as much as required.
2.3
1 Here the solar energy will be utilized with priority whenever possible. The additionally required
heat will be provided by the producer.
2 In addition to 1) the producer will operate based on demand with the minimally required
temperature resp. only as long as the storage demand requires.
2.4
0 The hot water circulation pipe from the storage tank to the consumer loses considerable amounts
of energy when operating continuously. The storage tank temperature drops due to the
continuous energy losses. Frequent recharging is required to cover the losses.
1 The circulation is operating when reasonable for the building. With the losses will be reduced and
there is limited unnecessary warm water circulation.
