PARALLEL CONNECTION OF MULTIPLE SYSTEMS
notes
1.
All the branch lines to the sto
-
rage tanks must have same
length and geometry (diame
-
ter of tube, curves… etc)
2.
Pressure drop (¢p) must be
almost the same in hot and
cold-water tubes

SERIAL CONNECTION OF MULTIPLE SYSTEMS
(It is recommended the installation of maximum five appliances)
In multiple connections where the electric
resistance is used, you should avoid connec
-
ting the electric resistance in the storage
tanks of the first two appliances. These
appliances will be used to pre-heat the water
for the consumption.
For this kind of installation (or for more than
three solar water heaters connected in a row)
you have to make a special request for 3/4”
inlets-outlets pipes on the storage tank. We
recommend you to use a maximum of five
appliances.
All the piping in 20 mm diameter.
