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 the 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 Caesar Eco 11 or Caesar Eco 14 water
heater, use the package fiche in
Fig. 39
.
To complete it properly, fill the relevant spaces
(as shown in the assembly sheet facsimile
Fig. 37
)
with the values shown in tables
Fig. 38
.
The remaining values must be obtained from
the technical data sheets of the products used
to make up the assembly (e.g. solar devices, in-
tegration heat pumps, temperature controllers).
Use board
Fig. 39
for “assemblies” related to the
domestic hot water function (e.g.: water heater
+ solar thermal system).
