Rating of the TOP-12 voltage stabilizers for a gas boiler in 2022: which one to choose, an overview of the best models

Voltage stabilizer for a gas boiler - review and rating. Description, characteristics, advantages and disadvantages of the best models. What to look for when choosing a voltage stabilizer for a gas boiler.

For the protection and reliable operation of an electric gas boiler, a network stabilizer is required.

This connection option relevant in case of drops, unexpected shutdowns, increased or decreased voltage in the network.

Which voltage stabilizer for a gas boiler to choose and what to look for when choosing, we will consider in this review.

Criteria for choosing a voltage stabilizer for a gas boiler

The most common are electromechanical with a servo system, relay with step voltage regulation, inverter with double energy conversion and hybrid models.

Inverter stabilizers are the most accurate and progressive, relay ones are the cheapest and most common.

When choosing this equipment, it is necessary to take into account a number of points:

Number of phases.
Domestic gas boilers are mainly designed for connection to a single-phase 220 V electrical network.
Powerful three-phase equipment provides for power supply from a three-phase 380 V network and the choice of an appropriate stabilizer.
Load power.
The output power of the stabilizer must correspond to that of the gas equipment.
The average boiler power for a small private house is 150-200 W, while the consumption at start is 2-3 times higher than the nominal parameter.
stabilization speed.
The characteristic reflects the time spent on equalizing the output voltage.
A high stabilization rate with a reduction in the response time of the system in case of deviations guarantees the protection of the boiler against breakdowns and its stable operation.
Input voltage.
Extreme network deviations up or down can easily disable the connected equipment.
For this reason, for a gas boiler, it is recommended to choose a stabilizer with the widest input voltage range.
Output voltage.
For operation with a gas boiler, a stabilizer with a tolerance of ±10% is recommended.
There are also more accurate devices that completely eliminate malfunctions and increase the working life of the connected equipment.
Other options.
Modern network stabilizers are equipped with a number of useful options and features.
These are, for example, electronic protection against overheating / overload / short circuit / mains failures, automatic restart, network filters, digital or LED indication.
Advanced functionality contributes to the convenience and better performance of the stabilizer.
