SolarTank
Heating water storage tank, 300-3000 litres

SolarTank is our range of vessels that store primary energy
from different heat sources including boilers, solar heaters,
heat recovery systems and others. This leaflet describes the
standard cylinders that are available in capacities between
300 and 3000 litres and rated for 10 bar operation pressure.
Pressure vessel code
SolarTank meets the requirements of the PED 97/23/EEC
code.
Freshwater heating on demand
SolarTank is designed for use in combination with instanta­
neous tap water heaters. The SolarTank can store energy from
any heat source to generate hot tap water on demand in
facilities where water flow is not constant – where sudden
high demands occur on a fairly regular basis such as in blocks
of flats, sports centres, schools, hotels and hospitals. When
discharging the SolarTank in combination with an instanta­
neous tap water heater, the primary power demand can be
substantially reduced since the SolarTank acts as a buffer
on the primary side to meet the power peaks that occur at
high tap water flow rates. Following such high tap water
consumption, heating takes place very quickly and only on
demand. This ensures a hygienic hot tap water supply that
reduces the risk of lime scaling in the tap water system and
scalding at the tap.
Flexible energy sources
The SolarTank can be connected to any type of primary heat
source as long as it is connected in a closed heating loop. To
heat tap water to the right comfort level when showering and
bathing, we recommend a minimum charging temperature of
45 to 50°C for the primary heating water.
High effectiveness for maximum hot water
The effectiveness of this type of energy storage tank from
which hot tap water is generated depends on its abil­
ity to keep the hot heating water separated from the cold
return water that is admitted into the tank. The SolarTank
is ­ articularly positive in this respect due to its internal tube
p
arrangement. The returned cold heating water is distributed
gently across the bottom of the tank, which prevents it from

mixing with the hot water that is fed on top of the vessel.
The hot heating water is then drawn from the very top at the
centre of the cylinder and is supplied to the instantaneous
tap water heater. Moreover, since vertical storage tanks are
more effective than horizontal ones, the SolarTank has an
upright design.
Effective and environmentally friendly insulation
The insulation is made of 100mm rockwool cladded with an
alaminium metal plate (Euroclass A) or 100mm glasswool
with a PVC jacket (Euroclass B). The insulation is very easy
to remove and refit, which makes the unit easy to transport in
and out of the premises.
