1.2 Intended Use
NIBE hot water storage tanks with one coil are only intended
for hea ng up, storage and supply the domes c hot water.
Ver cal storage tanks with one coil of BA-ST Series are desi-
gned to heat and store hot water in systems with two heat
sources, e.g. solar hea ng system with a central hea ng boiler
or central hea ng boiler with a  replace and with a water jac-
ket. The storage tank enables trouble-free opera on with al-
most any central hea ng system with forced circula on. They
are easy to install, safe and comfortable to use, if installed
and operated in accordance with the advices contained in this
Manual. The heated water can be supplied to several intake
points at various, mutually distant loca ons, such as, a bath-
tub, washbasin, sink, etc.
Storage tank with one coil are designed to heat up and
supply water for domes c purposes. Any inappropria-
te use, not in compliance with its intended use is not
permi ed. Neither manufacturer nor supplier shall be
responsible for damages resul ng from this.

2. DESIGN
Ver cal storage tanks with one coil of BA-ST Series are pressu-
re equipment, i.e. the pressure within the storage tanks and
coil are equivalent to the pressures in the corresponding sys-
tems.
All products are ready for the installa on of a hea ng
unit containing an electric heater with thermostat and
thermal switch.
Informa on
Storage tank is made of high quality steel and is equipped
with one helical coil that can simultaneously operate with in-
dependent heat source, e.g. a solar hea ng system,  replace
with water jacket or central hea ng boiler. In each version,
the hot water tank is protected against corrosion by ceramic
coa ng and insulated protec ve magnesium anode. The coil
is not internally protected against corrosion. Thermal insula-
 on of the tank is a specially selected insula on that provides
excellent thermal insula on proper es of all devices. Storage
tanks have aesthe c plas c housing, a temperature indicator,
inspec on opening and connectors for moun ng electric he-
a ng unit and connec ng the hot water circula on.

INSTALLATION AND OPERATING MANUAL
3. INSTALLATION
3.1 Loca on of the Storage Tank
Storage tank can be installed in any room protected against
temperatures below 0 °C and convenient for the user (e.g.
in the basement, boiler room, etc.). Loca on and manner of
installa on must ensure trouble-free maintenance and servi-
cing of the unit in the future. However, we recommend in-
stalla on of the bu er tanks in the immediate vicinity of the
main heat source in order to avoid unnecessary heat losses.
Consider the  lled tank weight when selec ng its loca on. As
a rule, select the device loca on in a way allowing the ra onal
rou ng of both the hot water and the hea ng lines. Insulate
thoroughly all hydraulic lines and the storage tank   ngs in
order to avoid any energy losses.
When installing the storage tank, consider free space
above the unit required to maintain/replace the protec-
 ve magnesium anode.
Informa on
If space for the installa on of the magnesium bar anode
(used as standard), you can use the appropriate  tanium
anode (that should be installed in accordance with the anode
manufacturer’s instruc ons) or the appropriate magnesium
chain anode. For the specifi ca on of the protec ve anodes
available at NIBE, see Sec on 6 Accessories and Spare Parts.
Fig. 6 Min clearance for the replacement of the protec ve
magnesium anode.
You can decrease the Amin clearance when using the ma-
gnesium chain anode or  tanium anode.
Informa on
Fig. 7 Levelling the unit.
The storage tank stands on three feet that can be adjusted
within the range from 0 to 15 mm to level the tank.
3.2 Housing Disassembly
Removable housing with thermal insula on facilitates trans-
port and installa on of the storage tank. Disassembly the ho-
using in the following order (see Fig. 8):
1. Remove the Temperature gauge, plug of the hea ng ele-
ment connector pipe and blanking plate of the inspec on
opening.
2. Remove the upper cover of the housing together with
thermal insula on.
3. Remove the plugs from the connector pipes and black
bushings.
4. Remove the  xing screws and the strip connec ng the
housing jacket.
5. Remove the jacket surrounding the tank (housing jacket.)
6. Remove the four-piece thermal insula on.
A er the installa on of the storage tank in its  nal loca on,
reinstall the removed components in the reverse order.
For the minimum clearances to be observed when instal-
ling the storage tank, see Table 4.

3.3 Installa on Requirements
Installa on and commissioning of the storage tank
shall only be done by appropriately quali ed installer.
The installer should inform the user of the func ons of
the product and provide the necessary informa on on
its safe use.
CAUTION
The coil in BA-ST 9022-9100-1FE storage tanks is not in-
ternally protected against corrosion. The coil may only be
 lled with a hea ng medium (hea ng water) that meets
the requirements of VDI 2035 part 1 and 2.
CAUTION
Protec on against overpressure shall be made in accordance
with the relevant regula ons in force.
Connect the storage tank to the water supply system of water
pressure at least 1 bar and max 10 bar (BA-ST 9022 - 1FE up
to 6 bar) and to the hea ng systems where parameters of the
hea ng medium may not exceed the allowable opera ng con-
di ons of the coil (see Table 5 Technical data). Install a pressu-
re reducer if the pressure at the cold water inlet to the tank is
higher than allowed.
Connect the hea ng and water supply systems in accordance
with the installa on diagram (see Fig. 9.)
Pressure increases during hea ng the water in the storage
tank. Therefore, the appropriate safety valve must be installed
in each storage tank, at the cold water inlet that will protect
the storage tank against overpressure. During hea ng the wa-
ter, small and temporary water  ow from the safety valve can
occur, which indicates that the pressure has increased above
the rated value, which triggered the valve. This may in no way
be prevented. Blocked safety valve can cause equipment fa-
ilure. Drain the ou low from the safety valve to the sewerage
or drain grate. Safety valve drain line should be installed with
a decline, in an environment free of freezing and remain open
to the atmosphere. The manufacturer is not responsible for
 ooding the room through the safety valve.
In order to minimize the  ow of water from the safety valve
associated with the thermal expansion of the liquid, it is advi-
sable to install a suitable expansion vessel at the cold water
connec on (see Fig. 9 item 9.)
Informa on
We recommend installing a strainer in order to protect
the pumps, check valve and the components of the he-
a ng system.
Informa on
Installa on of the appropriate safety valve in the cold
water supply line protec ng the unit against over-
pressure is mandatory!
CAUTION
Installa on of necking of any kind (such as reducers,
dirt pockets, etc.) and cut-off valves between the stora-
ge tank and the safety valve is not allowed. Only a T-pi-
pe with a drain valve and a T-pipe with an expansion
vessel may be installed in these line sec ons.
CAUTION
Never block the safety valve or drain line. This can cau-
se a dangerous overpressure in the storage tank.
CAUTION
When hea ng water, slight, temporary discharge from
the safety valve can occur. This is a correct safety valve
func on. Any a empt to interfere in its opera on can
lead to the danger and destruc on of the storage tank.
CAUTION
Never use the equipment with clogged safety valves.

4.1 Connec on
1. Remove protec ng plugs from the connector pipes
2. Connect the hot water intake line (12).
3. Connect the cold water supply line together with the
required safety valves (19).
4. If the system has the hot water circula on system, connect
it to the connector pipe (14). Otherwise, plug the pipe.
5. Connect the supply (13) and return (16) of the hea ng
medium to the coil.
4.2 Start-Up
Fill the storage tank with water and vent it a er making cor-
rect connec ons.
If there is an electric hea ng module installed in the
storage tank,  ll the tank with water before connec ng
it to the electrical installa on.
CAUTION
1. Open the cold water cut-o valve at the inlet and the hot
water intake point.
2. Fill the storage tank un l obtaining uniform water ou low
at the hot water intake point. Close the intake points.
3. Fill the coil with the hea ng medium, and vent it.
4. Check  ghtness of the en re system.
5. Check the  ghtness of the hea ng module connec on pipe.
When properly  lled and vented, the storage tank is ready to use.
A er the installa on and levelling the tank, follow the procedure
below (for the connector pipe numbers, refer to Fig. 3 and Fig. 5):
Filling and ven ng the hot water storage tank:
Open the hot water intake valves before hea ng the
system up for the  rst  me or a er a longer break in its
opera on in order to check whether the storage tank is
 lled with water and the cut-off valve at the cold water
inlet is not closed.
CAUTION
4.4 Warnings and Prac cal Recommenda ons
• Check the opera on of the safety valve as described by
the manufacturer of the valve in order to check whether
it is not clogged.
• Clean the inside of the storage tank periodically. Cleaning
intervals depends on the hardness of the water present
in a given area.
• To ensure op mum protec on of the storage tank against
corrosion, we recommended checking the level of wear
of the isolated magnesium anode once a year.
We recommend the following:
4.3 Thermal Insula on of the System
In order to minimize thermal energy losses, insulate all con-
nector pipes, pipelines and temperature sensor covers tho-
roughly a er the installa on of the unit and performance of
the leak proof test. For this purpose, use thermal insula on
of correctly selected thickness and thermal insula on para-
meters.
Lack of thermal insula on, its incorrect thickness or in-
sula on made of inadequate materials will cause decre-
ase of thermal insula on proper es of the unit and the
system.
Informa on
We recommend connec ng the tank connector pipes
with the system lines by means of unions to allow discon-
nec on of the tank, if required.
Informa on
To prevent bacterial growth we recommend to make
sure a periodically increase of hot water temperature for
a shorter  me at regular intervals e.g. every 14th day.
CAUTION
INSTALLATION AND OPERATING MANUAL
The plug on the connec on pipe of the hea ng module
is an exploita on element, therefore it is necessary to
check its  ghtness before using the tank.
CAUTION
The storage tank connec ons may not be made of
materials more precious than carbon steel due to the
increased electrochemical corrosion. This applies to
connector pipes (  ngs) contac ng the tank connec-
tor pipe thread. Preferably, use galvanized pipe con-
nectors (  ngs.)
CAUTION

Hot Water Storage Tank with One Coil
BA-ST 9022/9100 - 1FE
INSTALLATION AND OPERATING MANUAL
• The isolated protec ve anode earth conductor must be con-
nected to the steel components of the storage tank (top bot-
tom of the tank). Otherwise, the tank will not be protected
against corrosion.
• In order to eliminate any odour of hydrogen sulphide (caused
by bacteria in the oxygen de cient water), we recommend
observing the periodic cleaning of the tank and replacement
of the anode and, in addi on periodically increase the hot wa-
ter temperature in tank to prevent bacterial growth.
• In the systems with the electric hea ng unit, ensure that the
electrical installa on is properly protected by protec ve cir-
cuit.
• Limit the setpoints of the hea ng medium temperature con-
trollers in the storage tank supply lines to 80 °C in order to
avoid triggering of the thermal cut-o in the electric hea ng
module.
• In order to reduce the possibility of scalding by the water, we
recommended to set the water hea ng temperature in the
storage tank (of both the hea ng unit and the coil) so, that it
does not exceed 60 °C. This will also help to extend the life of
the storage tank.
• Report any malfunc ons in the storage tank opera on to the
authorized service centres. You can  nd the complete list of
our authorized service centres at our website.
It is forbidden to:
• ac vate the hea ng medium circuit or electric hea ng
unit if the tank is not  lled with water
• use the storage tank, if you  nd any malfunc on of the
safety valve
• install any device (such as cut-o and/or check valves,
etc.) between the storage tank and the safety valve (ex-
cept T-pipes)
• make any unauthorized repairs
• stop water leaks from the safety valve
• when hea ng with only the electric unit, the coil circuits
may not be isolated
5. MAINTENANCE
Periodic inspec ons and maintenance are the condi ons of
con nuous opera onal readiness, reliability and a long servi-
ce life of the product.
Maintenance ac vi es include the following:
• rou ne inspec ons and replacement of the protec ve
magnesium anode
• cleaning of the storage tank
5.1 Inspec on of the Protec ve Magnesium Anode
Storage tanks with one coil of BA-ST Series are, in order to
protect them against corrosion, coated inside with ceramic
enamel and in addi on, protected with isolated protec ve
magnesium anode. The anode corrodes  rst under normal
opera on, thus protec ng the storage tank jacket. Therefore,
you have to inspect its condi on from  me to  me. Corrosion
rate of the protec ve anode is di erent and depends upon
the quality of water in the area. We recommend checking the
protec ve anode condi on once a year in order to ensure
op mum corrosion protec on.
The use of the isolated anode allows you to monitor the
degree of wear of the anode by measuring the intensity
of the protec ng direct current without having to remo-
ve it and empty the tank (interrup ng opera on of the
storage tank). This solu on simplifi es opera on and ad-
di onally contributes to the reliability and long life me.
Informa on
Fig. 10 Insulated protec ve magnesium anode
5.2 Measurement of the Protec ve Magnesium Anode Wear
In order to check the degree of wear of the anode, do the
following (see Fig. 11):
1. Remove the housing cover together with thermal insula on.
2. Disconnect the connec ng conductor (protec ve) from
the storage tank top head.
3. Connect an electric meter (range in mA) between the
protec ve conductor and the M5 threaded pin and me-
asure the intensity of the protec ve direct current.
Intensity of the protec ve direct current should not be lower
than 0.3 mA at full storage tank. If it is too low, remove the
anode and check its wear visually. If the anode is signi cantly
corroded (above 50 % loss), replace it immediately. Connect
the anode protec ve conductor to the tank a er the measu-
rement.
If the current intensity measurements do not indicate
any wear of the anode, its max opera ng  me is not
longer than 18 months. The anode should be replaced
a er this  me.
CAUTION

before each start-up of the heater a er decommissio-
ning.
CAUTION
Systema c admission of fresh, untreated water to the
hea ng circuit (coil) increases the risk of corrosion inside
the coil.
CAUTION

INSTALLATION AND OPERATING MANUAL
When replacing the magnesium anode, follow the procedure
below (see Fig. 12):
1. In units with the electric hea ng unit installed, discon-
nect power from the unit  rst.
2. Switch the storage tank coil heaters OFF and wait un l
the water inside cools down.
3. Cut-o the hot water supply and drain some water from
the tank through the drain valve (see Fig. 9 item 4).
4. Remove the housing cover together with thermal insula-
 on (1).
5. Remove the anode protec ve conductor (2).
6. Remove the worn magnesium anode (3).
7. Screw the new magnesium anode.
8. Connect the anode protec ve conductor to the storage
tank.
9. Fill the tank with water and vent it as described in par. 4.2
Start-Up.
10. Check  ghtness of the installed anode.
11. Reinstall the thermal insula on and the housing cover.
Once making the above steps, the storage tank is ready to use.
Ensure that the anode protec ve conductor is connected to
the storage tank top head a er installing the new isolated ma-
gnesium anode. Lack of contact between the anode and the
tank will interfere opera on of the anode and the tank will
not be protected against corrosion.

5.4 Cleaning of the Storage Tank
Boiler scale is precipitated from the heated water during the
storage tank opera on. The amount of deposited scale de-
pends on the water hardness, the opera ng temperature and
opera ng  me. Hea ng surfaces covered with boiler scale re-
duce the heat output of the storage tank, increase power con-
sump on and extend the hea ng  me. It is recommended to
clean the storage tank from deposits at least once every two
years. In the case of hard or very hard water, cleaning should
be carried out at shorter intervals.
Storage tank cleaning procedure:
During mechanical cleaning, be careful to not damage
the enamel. In the case of chemical cleaning, pay special
a en on to neutralize the chemicals used for cleaning.
Informa on
Connect the anode protec ve conductor to the M5 pin  xed
to the top head of the storage tank.
Once cleaned, the unit is ready to use.

plate.
5.3 Replacement of the Protec ve Magnesium Anode
Replace the protec ve magnesium anode every 18 months
(regardless the measurement). Instead of the magnesium
anode, you can use the  tanium anode. Install it in accordan-
ce with the anode installa on manual.
Replace the protec ve magnesium anode every 18
months. Its  mely exchange and proper installa on
are the condi ons to maintain the warranty on the sto-
