ALU-EPS insulation (reflector only included in
COMFORT-PRO Line):
ALU-EPS insulation greatly reduces heat losses. The cylinder
reflector significantly reduces dissipation losses. The EPS
foam used has a good insulating value.

Connections with thermal breaks:
Due to the siphoned fitting of the copper and steel connec-
tions to the cylinder, the otherwise high heat losses are
greatly reduced. Special baffles are fitted in the tank to pre-
serve the feeding stratification.

Combined baffle:
SOLUS combined storage tanks type 2008 have been spe-
cially developed for efficient operation in conjunction with
heat pumps.
The combined baffle is used for low turbulence stratification
of large heat pump supplies, designed for 30 l/min (higher
flow rates result in a larger mixing zone).

2.1
Transport
The storage tanks may only be transported vertically in ve-
hicles. For carrying, there are handles on the storage tanks.
Storage tanks may only be lifted freely if all handles are
used simultaneously.
2.2
Connection to the drinking water supply
Hot water circulation:
The circulation line is connected to the cold water connec-
tion of the storage tank. As in all water heaters, hot water
circulation entails significant heat losses. This also gradually
reduces stratification. The circulation pump should not run
continuously, as otherwise unnecessarily high heat losses
result in the piping system. For this reason, we recommend
operating the circulation pump with temperature control or
in interval mode (most CONTROL controllers contain this
function).
Mixed installation:
When the SOLUS II storage tanks are connected to a galva-
nised steel hot water pipe, the steel pipe may be corroded
when newly installed in particular due to the electrochemical
series. If you want to avoid this risk, you should not use the
storage tanks. If you are in doubt,
the Consolar support team will be happy to advise you.
Water quality:
The quality of the water used to fill the tank must comply
with VDI 2035 for heating water.
NOTE:
Suitable measures (flushing the system, filters etc.) must
be taken to ensure that existing components in the heat-
ing system do not allow other materials and substances
(e.g. sludge, leak sealant, anticorrosive agents etc.) to
enter the storage tank.
The pH value of the drinking water connected to the hot
water heat exchanger must be between 7.4 and 9.5. If the
pH value is between 7.0 and 7.4 the TOC value may not
exceed 1,5 mg/l (g/m
3
) (in accordance with DIN 50930-
6). If the water hardness is 8° dH or more, rinsing taps are
recommended for the cold water inlet and the hot water
outlet. For use with water high in limescale, limescale ex-
perts recommend limescale conversion or water treatment
processes for all solar heating systems with 14° dH and
upwards (hard water). You can ask your local water supply
company to find out the water hardness. Ask your installer
for advice on this matter.
Expansion vessel:
Volume compensation vessels, which compensate for ther-
mal expansion, are not necessary for the SOLUS II series,
