The energy efficiency of the set of products indicated in this sheet may not reflect the actual
energy efficiency after installation since such efficiency is affected by additional factors, such as
the heat loss in the distribution system and the size of the products compared to the size and
features of the building.
Facsimile for filling in domestic hot water production system package fiche.
3.13 PARAMETERS FOR FILLING IN THE
PACKAGE FICHE.
Should you wish to install an assembly, starting
from the Julius (11 4 o 14 4) ErP water heater,
use the package fiche in Fig. 3-6.
To fill it in correctly, enter the figures shown
in table Fig. 3-5 (as shown in the package fiche
facsimile Fig. 3-4) .
The remaining values must be obtained from
the technical data sheets of the products used to
make up the assembly (e.g. solar devices, integra-
tion heat pumps, temperature controllers).
Use sheet fig. 3-6 for “assemblies” related to the
domestic hot water function (e.g.: water
solar thermal system).
