Protect sensitive equipment from damage! Voltage stabilizer for gas boiler Baxi

The operation of any modern gas boiler is controlled electronic control board, which can be very sensitive to voltage surges and noise interference in power supply networks.

Of course, manufacturers install built-in voltage regulators in power supplies for these boards, but in Russian conditions they may not be enough. To provide the boiler with the ideal voltage And protect it from failures and a stabilizer is needed.

You may already have an erection uninterruptible power supply (UPS) or even backup generator — however, a stabilizer will also be required, because not all UPS and especially generators are equipped with a good stabilization unit, and in cheap models (off-line circuitry) it is completely absent.

How to choose voltage stabilizers for Baxi gas boilers

Many manufacturing companies make products that are designed specially for the Russian market, adapted to our harsh climatic and living conditions.

The same applies to devices from domestic manufacturers, but Italian boilers Baxi often refuse to work in Russia. due to problems with the supply voltage.

Users note that these The devices are “capricious” even with some stabilizers. Therefore, the choice of a protective regulator for Baxi should be approached carefully, especially in relation to the technical characteristics discussed below.

Power

The good news is that Baxi boilers are very economical and do not consume more than 170 W, which allows you not to take too powerful a stabilizer, overpaying for its reliability. For devices without a built-in circulation pump, it is enough to take a reserve on top in 15-20%. For models with a pump, due to the starting currents of the electric motor, we multiply the nominal power specified in the instructions on 3.

Input voltage range

Shows the limits to which the stabilizer can perform its function.

Usually, when the voltage goes beyond this range, the stabilizer goes into protection mode and disconnects the load from the network.

You can find out the range of voltage surges in your area using a voltmeter or multimeter, measuring the voltage in the socket at different times of the day.

It is necessary to select this parameter correctly, otherwise constant shutdown of the boiler will lead to poor heating.

Stabilization accuracy

An important characteristic that describes how accurately the device can maintain the desired output voltage. For Baxi, it is necessary stabilization accuracy 5-8%, less is better. Accuracy depends on the operating principle (circuitry) of the stabilizer. Thus, in stabilizers with a transformer, accuracy is determined by the number of windings.

The same concept should include the response time of the stabilizing device to changes in the power supply. It is the highest (absent) for inverter devices, and electromechanical stabilizers are the slowest to respond. The recommended value for gas boiler units is 30-40 ms (less is better).

Suitable stabilizers for different series of Baxi boilers

Different Baxi boiler model ranges require different stabilizers.

Luna

Power consumption of Luna series boilers:

All models of the series are equipped with built-in circulation pumps, so we will increase this power 3 times, we will get the maximum value in 510 W. This is the minimum required stabilizer power for Baxi Luna boilers (the exception is the economical one) LUNA-3 COMFORT 240 i, for which the regulator is suitable 240 W).

Slim

Power consumption of popular models of the Slim line:

Not all models are listed in the table, but the power of those not listed also does not exceed 170 W.

Slim boilers with index N do not have a built-in pump, so if you are planning a system with natural circulation, then when choosing a stabilizer there is no need to take a power reserve 3 times, a device in will be enough 100 W. For boilers with a built-in pump, the same devices are suitable as for the Luna line; let's consider models suitable only for pumpless boilers.

Ensure reliable and long-term operation of your heating appliance

Baxi gas boilers are economical and do not require a powerful and expensive stabilizer, and a small additional expense on a protective device can save your nerves on cold winter days. When installing the purchased stabilizer, remember the safety precautions:

• The device cannot be placed close to the boiler and gas lines, and also in damp places.
• Provide him with good ventilation and cooling.
• Connect the ground, keep the phasing.
• Involve a qualified specialist, if you do not have knowledge in electrical engineering.
