Technical characteristics of stabilizers
Stabilizers are built on the basis of an autotransformer or on the basis of an inverter (also called double conversion stabilizers).
In devices with a transformer, the transformer windings are switched using switching elements:
- Thyristors - the fastest response speed, silent operation, durability.
- Relay - average reaction speed, clicks during operation, average service life.
- Servomotors (electromechanical) — low speed, noise (buzzing during operation), short service life.
Attention! Electromechanical stabilizers, despite their shortcomings, provide smooth (without step surges) voltage regulation.
Inverter stabilizers similar to on-line UPS, but without batteries: The input AC voltage is rectified and filtered, and then an ideal sine wave with stable voltage is recreated using transistors or thyristors. These devices provide high-quality and reliable voltage conversion.
Input voltage
When choosing a device, Please note the input voltage range.
It shows the limits to which the stabilizer copes with its function.
When the limits of this range are exceeded, the device goes into protection mode and disconnects the load from the networkTherefore, incorrect selection of this parameter leads to frequent boiler shutdowns and poor heating quality.
Reference. You can find out the range of voltage surges using voltmeter or multimeter, inserting it into the socket. The lowest values are observed during the evening peak load (from 18:00 to 23:00), and the highest ones are at night. After taking measurements, add a certain reserve to the results (10-15%).
Power
The power consumption of gas boilers is low and is within the range 200-300 W. But there is one nuance: devices with an electric motor (pumps, valves) consume a short-term amount of power at the moment of start-up. 3-4 times more energy.
Therefore, the nominal power of such devices, indicated on the body or in the instructions, is multiplied by at least on 3 (perfect - by 5).
The boiler may already have a built-in circulation pump, or there may be external ones.
To prevent the stabilizer from going into overload, turning off the heating equipment, do not forget to increase the power of the pumps by the specified number of times. Then sum up all the powers, add 5-10% - get the required stabilizer power.
Important! Sometimes power is indicated in volt-amperes (VA, VA). To get the value in watts, multiply it by 0.8.
Efficiency
The efficiency factor shows what percentage of power goes to power the boiler and what is lost in the stabilizer. Modern models have a high Efficiency: 92-96%, and due to the low power of the boilers, the losses at any efficiency will be small - therefore, you should not pay special attention to this parameter, but rather consider the reliability and user reviews.
Stabilization accuracy
An important characteristic, indicated in percent. For gas boilers, an accuracy of at least 4-5%, less is better.
Highest accuracy for inverter and electromechanical models. In relay or thyristor types it depends on the number of windings in the transformer.
Don't forget about the response speed. It all depends on the network conditions.
For long-term power supply fluctuations without sudden surges, but large in amplitude, give preference electromechanical or relay stabilizer. Lots of ups and downs - electronic thyristor.
If welding is often carried out or many electric motors (machines, lawn mowers, etc.) are operating nearby, only an inverter is suitable, since noise interference and distortion of the sine wave shape cannot be smoothed out by any transformer-based stabilizer. Typical response speed values that do not cause interruptions in the boiler operation are: 30-40 ms.
Rating of the best stabilizers for gas boilers
Among the voltage stabilizers for gas boilers, the following models are popular.
BASTION Teplocom ST-222 500
The stabilizer from Bastion is worth choosing if there are no serious surges in the network, since it does not have sufficient adjustment accuracy. The power is also low, but the advantages: universal installation on DIN rail or wall, compact body with built-in socket and manufacturer's warranty 5 years - make it a worthy competitor to other review models.

It's better to overpay first than later
Repairing the control board of a gas boiler can result in 30-40% from its cost, and the most affordable models of stabilizers cost 5-10% from the boiler. But the worst case scenario is to stay in a cold house in winter and call the service department. All this can be prevented by buying a voltage stabilizer. As expected, the best in the rating were electronic stabilizers, especially Energy Classic 7500 for the optimal price/functionality ratio.
