Frequently Asked Questions - BA-ST 9030-2FE Nibe

What is the intended use of the Nibe BA-ST 9030-2FE?

It is designed to heat up, store and supply domestic hot water in systems with two heat sources, such as a solar heating system combined with a central heating boiler or a fireplace with a water jacket.

What are the minimum clearances required for installation?

Refer to the manual for specific dimensions (Table 4). For the BA-ST 9030-2FE, the minimum clearance above the tank for anode replacement is 980 mm (A_min). Always ensure enough space for maintenance and servicing.

Why is a safety valve mandatory?

A safety valve must be installed on the cold water inlet to protect the tank from overpressure. During heating, slight water discharge from the valve is normal and indicates proper function. Never block or tamper with the safety valve as it can cause dangerous overpressure.

How often should the protective magnesium anode be inspected?

We recommend checking the anode condition at least once a year. The isolated anode allows monitoring by measuring the protective direct current (should be ≥0.3 mA). Replace the anode every 18 months regardless of the measurement to maintain warranty.

How do I clean the storage tank?

Clean the tank at least every two years to remove scale. Drain the tank, remove the inspection opening cover, flush out sludge and lime deposits, then replace the gasket and tighten to 35±5 Nm. Be careful not to damage the ceramic enamel coating.

What water pressure is required for operation?

The cold water supply pressure must be between 1 bar and 10 bar (for BA-ST 9030-2FE). If the pressure exceeds 10 bar, install a pressure reducer.

Can I use the tank without water in it?

No. Never activate the heating medium circuit or electric heating unit if the tank is not completely filled with water. Operating an empty tank can damage the unit and pose safety risks.

What should I do if the safety valve leaks continuously?

Continuous leaking may indicate overpressure or a faulty valve. First, check if the system pressure is too high (install an expansion vessel if not present). If the problem persists, contact an authorized service center. Never block the valve.

How do I replace the magnesium anode?

Disconnect power, cut off water supply, drain part of the tank, remove the housing cover, disconnect the protective conductor, unscrew the old anode, screw in a new one, reconnect the conductor, refill and vent the tank. Ensure the protective conductor is firmly connected to the tank top head.

What is the maximum temperature setting to avoid scalding?

We recommend setting the water heating temperature to no more than 60 °C to reduce the risk of scalding and extend the life of the tank. Higher temperatures may be used periodically for bacterial control (e.g., 60 °C or above for short periods).

3. INSTALLATION

3.1 Locati 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.). Locati on and manner of installati on must ensure trouble-free maintenance and servicing of the unit in the future. However, we recommend installati on of the buffer tanks in the immediate vicinity of the main heat source in order to avoid unnecessary heat losses. Consider the fi lled tank weight when selecting its locati on. As a rule, select the device locati on in a way allowing the rati onal routing of both the hot water and the heating lines. Insulate thoroughly all hydraulic lines and the storage tank fittings in order to avoid any energy losses.

Information

When installing the storage tank, consider free space above the unit required to maintain/replace the protective magnesium anode.

If space for the installation of the magnesium bar anode (used as standard), you can use the appropriate titanium anode (that should be installed in accordance with the anode manufacturer's instructions) or the appropriate magnesium chain anode. For the specific cati on of the protective anodes available at NIBE, see Secti on 6 Accessories and Spare Parts.

Fig. 6 Min clearance for the replacement of the protective magnesium anode.

CAUTION

For the minimum clearances to be observed when installing the storage tank, see Table 4.

-Information

You can decrease the A_min clearance when using the magnesium chain anode or ti tanium anode.

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 insulation on facilitates transport and installation of the storage tank. Disassembly the housing in the following order (see Fig. 8):

1. Remove the Temperature gauge, plug of the heating element connector pipe and blanking plate of the inspecti on opening.
2. Remove the upper cover of the housing together with thermal insulation.
3. Remove the plugs from the connector pipes and black bushings.
4. Remove the fixing screws and the strip connecting the housing jacket.
5. Remove the jacket surrounding the tank (housing jacket.)
6. Remove the four-piece thermal insulation.

After the installation of the storage tank in its final location, reinstall the removed components in the reverse order.

Fig. 8 Housing and thermal insulation on disassembly

3.3 Installati on Requirements

Protecti on against overpressure shall be made in accordance with the relevant regulations 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 - 2FE up to 6 bar) and to the heating systems where parameters of the heating medium may not exceed the allowable operating conditions of the coils (see Table 5 Technical data). Install a pressure reducer if the pressure at the cold water inlet to the tank is higher than allowed.

Connect the heating and water supply systems in accordance with the installation diagram (see Fig. 9.)

Pressure increases during heating 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 heating the water, small and temporary water flow 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 failure. Drain the outflow 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 flooding the room through the safety valve.

-Information

In order to minimize the flow of water from the safety valve associated with the thermal expansion of the liquid, it is advisable to install a suitable expansion vessel at the cold water connection (see Fig. 9 item 9.)

Information

We recommend installing a strainer in order to protect the pumps, check valve and the components of the heating system.

CAUTION

Installati on of the appropriate safety valve in the cold water supply line protecting the unit against over-pressure is mandatory!

CAUTION

Installati on of necking of any kind (such as reducers, dirt pockets, etc.) and cut-off valves between the storage tank and the safety valve is not allowed. Only a T-pipe with a drain valve and a T-pipe with an expansion vessel may be installed in these line secti ons.

CAUTION-

Never block the safety valve or drain line. This can cause a dangerous overpressure in the storage tank.

CAUTION

When heating water, slight, temporary discharge from the safety valve can occur. This is a correct safety valve function. Any attempt to interfere in its operation can lead to the danger and destruction of the storage tank.

CAUTION

Never use the equipment with clogged safety valves.

4. CONNECTION AND START-UP

4.1 Connection

After the installation and levelling the tank, follow the procedure below (for the connector pipe numbers, refer to Fig. 3 and Fig. 5):

1. Remove protecting 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 circulati on system, connect it to the connector pipe (14). Otherwise, plug the pipe.
5. Connect the supply (13) and return (16) of the heating medium to the upper coil.
6. Connect the supply (17) and return (18) of the heating medium to the lower coil.

4.2 Start-Up

Fill the storage tank with water and vent it aft er making correct connecti ons.

CAUTION

If there is an electric heating module installed in the storage tank, fi ll the tank with water before connecting it to the electrical installation.

Filling and venting the hot water storage tank:

1. Open the cold water cut-off valve at the inlet and the hot water intake point
2. Fill the storage tank until obtaining uniform water outflow at the hot water intake point. Close the intake points
3. Fill the upper and lower coils with the heating medium, and vent them
4. Check tightness of the entire system

When properly filled and vented, the storage tank is ready to use.

Information

We recommend connecting the tank connector pipes with the system lines by means of unions to allow disconnect on of the tank, if required.

CAUTION

Open the hot water intake valves before heating the system up for the fi rst ti me or aft er a longer break in its operati on in order to check whether the storage tank is fi lled with water and the cut-off valve at the cold water inlet is not closed.

4.3 Thermal Insulation of the System

In order to minimize thermal energy losses, insulate all connector pipes, pipelines and temperature sensor covers thoroughly after the installati on of the unit and performance of the leak proof test. For this purpose, use thermal insulation on of correctly selected thickness and thermal insulation on parameters.

-Information

Lack of thermal insulation, its incorrect thickness or insulation on made of inadequate materials will cause decrease of thermal insulation on properties of the unit and the system.

4.4 Warnings and Practical Recommendations

-CAUTION

To prevent bacterial growth we recommend to make sure a periodically increase of hot water temperature for a shorter time at regular intervals e.g. every 14 ^th day.

We recommend the following:

• Check the operation 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 opti mum protecti on of the storage tank against corrosion, we recommended checking the level of wear of the isolated magnesium anode once a year.

• The isolated protective anode earth conductor must be connected to the steel components of the storage tank (top bottom 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 deficient water), we recommend observing the periodic cleaning of the tank and replacement of the anode and, in addition periodically increase the hot water temperature in tank to prevent bacterial growth.
• In the systems with the electric heating unit, ensure that the electrical installation is properly protected by protective circuit.
• Limit the setpoints of the heating medium temperature controllers in the storage tank supply lines to 80 °C in order to avoid triggering of the thermal cut-off in the electric heating module.
• In order to reduce the possibility of scalding by the water, we recommended to set the water heating temperature in the storage tank (of both the heating 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 malfunctions in the storage tank operation to the authorized service centres. You can find the complete list of our authorized service centres at our website.

It is forbidden to:

• activate the heating medium circuit or electric heating unit if the tank is not filled with water
• use the storage tank, if you find any malfunction of the safety valve
• install any device (such as cut-off and/or check valves, etc.) between the storage tank and the safety valve (except T-pipes)
  • make any unauthorized repairs
• stop water leaks from the safety valve
• when heating with only the electric unit, the coil circuits may not be isolated

5. MAINTENANCE

Periodic inspections and maintenance are the conditions of continuous operational readiness, reliability and a long service life of the product.

Maintenance acti viti es include the following:

• routine inspections and replacement of the protective magnesium anode
• cleaning of the storage tank

CAUTION

Check the safety valve performance as specified by the valve manufacturer periodically (min. every 14 days) or before each start-up of the heater after decommissioning.

5.1 Inspecti on of the Protecti ve Magnesium Anode

Storage tanks with two coils of BA-ST Series are, in order to protect them against corrosion, coated inside with ceramic enamel and in addition, protected with isolated protective magnesium anode. The anode corrodes first under normal operation, thus protecting the storage tank jacket. Therefore, you have to inspect its condition from time to time. Corrosion rate of the protective anode is different and depends upon the quality of water in the area. We recommend checking the protective anode condition once a year in order to ensure optimal corrosion protection.

-Information

The use of the isolated anode allows you to monitor the degree of wear of the anode by measuring the intensity of the protecting direct current without having to remove it and empty the tank (interrupting operation on of the storage tank). This solution simplifies operation and additionally contributes to the reliability and long lifeti me.

Fig. 10 Insulated protecti ve magnesium anode

5.2 Measurement of the Protecti 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 insulation.
2. Disconnect the connecting conductor (protective) from the storage tank top head.
3. Connect an electric meter (range in mA) between the protective conductor and the M5 threaded pin and measure the intensity of the protective direct current.

Intensity of the protecti 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 signifi cantly corroded (above 50 % loss), replace it immediately. Connect the anode protecti ve conductor to the tank aft er the measurement.

CAUTION

If the current intensity measurements do not indicate any wear of the anode, its max operating time is not longer than 18 months. The anode should be replaced after this time.

Fig. 11 Measurement of the protective direct current intensity

5.3 Replacement of the Protecti ve Magnesium Anode

Replace the protective magnesium anode every 18 months (regardless the measurement). Instead of the magnesium anode, you can use the titanium anode. Install it in accordance with the anode installati on manual.

CAUTION

Replace the protective magnesium anode every 18 months. Its timely exchange and proper installation are the conditions to maintain the warranty on the storage tank.

When replacing the magnesium anode, follow the procedure below (see Fig. 12):

1. In units with the electric heating unit installed, disconnect power from the unit first.
2. Switch the storage tank coil heaters OFF and wait until the water inside cools down.
3. Cut-off 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 insulation (1).
5. Remove the anode protecti ve conductor (2).
6. Remove the worn magnesium anode (3).
7. Screw the new magnesium anode.
8. Connect the anode protective conductor to the storage tank.
9. Fill the tank with water and vent it as described in par. 4.2 Start-Up.
10. Check tightness of the installed anode.
11. Reinstall the thermal insulation and the housing cover.

Once making the above steps, the storage tank is ready to use.

Ensure that the anode protective conductor is connected to the storage tank top head aft er installing the new isolated magnesium anode. Lack of contact between the anode and the tank will interfere operation of the anode and the tank will not be protected against corrosion.

Fig. 12 Replacement of the protective magnesium anode

Connect the anode protecti ve conductor to the M5 pin fi xed to the top head of the storage tank.

5.4 Cleaning of the Storage Tank

Boiler scale is precipitated from the heated water during the storage tank operation. The amount of deposited scale depends on the water hardness, the operating temperature and operating time. Heating surfaces covered with boiler scale reduce the heat output of the storage tank, increase power consumption and extend the heating time. 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:

1. Prepare a new inspecti on opening gasket. The old gasket may not be reused (for the list of the inspecti on opening gaskets, see Secti on 6 Accessories and Spare Parts).
2. In storage tanks with the electric heating unit installed, disconnect power from the unit first.
3. Switch the storage tank coil heaters OFF and wait until the water inside cools down.
4. Cut-off the hot water supply and drain the storage tank through the drain valve (see Fig. 9 item 4)
5. Remove the inspecti on opening blanking plate and gasket
6. Remove the inspecti on opening screws and flanged cover and flush the storage tank and remove accumulated sludge and lime slurry. If necessary, remove lime deposits from the coil – this guarantees a proper heat exchange. Pay special att enti on to not damage the ceramic enamel coati ng.
7. Replace a new gasket and the inspecti on opening flanged cover. Screw ti hightening torque: 35 ± 5 Nm.
8. Fill the tank with water and vent it as described in par. 4.2 Start-Up.
9. Check tightness of the inspecti on opening.
10. Replace the insulation and inspection on opening blanking plate.

Once cleaned, the unit is ready to use.

-Information

During mechanical cleaning, be careful to not damage the enamel. In the case of chemical cleaning, pay special att enti on to neutralize the chemicals used for cleaning.
