Rating of the best voltage stabilizers for gas boilers 2019: price review, reviews

The electronics of a modern gas boiler are very delicate things, and a sudden power surge can easily leave you without hot water and heating. To prevent this from happening, it is worth connecting the gas boiler through a voltage stabilizer. How to choose it and what 5 voltage stabilizers for gas boilers deserve the title of the best, we will now tell you.

Does a gas boiler need a voltage regulator?

Gas boilers are equipped with rather thin electronics, which are engaged in maintaining the desired temperature and pressure in the system. In principle, this allows the boiler to function without human intervention at all. But the fact is that the electronics of a gas boiler are very sensitive to the quality of electrical power. A voltage deviation of even 10% can lead to failure of the automation or to its malfunction, which means neither heat, nor hot water.

If within the city limits the tension is still more or less kept within the limits prescribed by GOST, then outside the city, especially in remote settlements, the leaps can be such that no boiler can cope with it. Therefore, yes, the gas boiler that you cherish needs a voltage stabilizer.

What to look for when choosing a voltage stabilizer for a gas boiler

A type. Voltage stabilizers can be:

• relay - inexpensive, with a wide range of operating voltages and fast response, but not very accurate;
• electromechanical - more expensive, slower and with a narrower operating range, but also with less error in operation;
• hybrid - electromechanical with an extended operating range of input voltages due to the installation of a special relay;
• electrodynamic - extremely accurate and very reliable, but at the same time very expensive;
• electronic - one of the most expensive on the market, but at the same time very accurate, fast and with a wide range of input voltages;
• inverter - the most modern and advanced in all basic characteristics.

Phase. Gas boilers, as a rule, operate on a single-phase 220 volt network. Three-phase boiler models are rather industrial solutions. So a stabilizer for the boiler is needed, most likely, a single-phase one.

Power. Insufficient power will not allow the stabilizer to do its job normally, and the excess power will simply idle idle. Therefore, a voltage stabilizer for a gas boiler must be selected taking into account the total power of the boiler itself and all pumps connected to it. Do not forget that the pump power during start-up approximately triples, and it is better to take the stabilizer with a margin of 20-30%.

Stabilization accuracy. Accuracy is never overkill. The error in the operation of the voltage stabilizer for a gas boiler should not exceed 8%.

Stabilization speed. It includes two points: the response time in milliseconds (it determines the speed of the stabilizer's response to a voltage change) and the rate of voltage change (volts per second). The smaller the first part and the larger the second, the better.

Working and limiting voltage range. Since the voltage in the network can simply jump within huge limits, it is desirable that these parameters be as wide as possible. This is especially true of the operating range, since at the limit the stabilizer will still not be able to work for too long.

Indication. It can be realized by means of LEDs (the cheapest option), a digital display (the most common option) and a web interface (an option for industrial use).

Installation. The least fundamental point. Usually, voltage stabilizers are installed on the floor or hung on the wall - this is a matter of taste and free space.

Top 5 best voltage regulators for gas boilers

Best electronic voltage regulator

1. Calm R 1200SPT

Far from the most budgetary, but very accurate and reliable thyristor-type electronic voltage regulator. Works in a single-phase 220 V. The apparent power is 1.20 kVA, the input operating voltage is 170-250 V, and the limit voltage is 150-265 V. Low error of 3.5% ensures output voltage in the range of 212-228 V. The response time does not exceed 40 ms. Protection against short circuit, overvoltage and interference is provided. LED indication of work, wall placement. The price of the issue is about 11,500 rubles, which is not so expensive for an electronic device with such parameters.

Best inverter voltage regulator

2. Calm IS550 (0.4 kW)

Not the most expensive inverter voltage regulator for a gas boiler with a price of less than 6,000 rubles. For this modest price, you will receive a device with an active power of 400 W and a full power of 550 VA. The device operates in a single-phase network and is capable of converting voltage in a wide range from 90 to 310 V with an accuracy of 2% (the output voltage ranges from 216-224 V). There is protection against short circuit, overheating, overvoltage and interference. LED indication of work is provided. A very neat and modern solution to the problem of power supply to a gas boiler, although the power reserve of this stabilizer is not the greatest.

Best Relay Voltage Regulator

3. RESANTA LUX ASN-1500N / 1-Ts (1.5 kW)

Wall Mounted Single Phase Relay Stabilizer with 2 outlet sockets. The device costs less than 3,000 rubles, but it produces quite a decent 1.50 kW of active power. Operates in a single-phase network with an input voltage of 140 to 260 V. The stabilization accuracy is typical for relay-type devices and is 8% (output voltage is 202-238 V), and the stabilization rate does not drop below 35 V / s. Gentleman's kit for protection against short circuit, overheating, overvoltage and interference - in place. There is a digital indication of the input and output voltage. A good inexpensive option.

Best wall-mounted voltage regulator

4. Huter 400GS (0.35 kW)

Relay voltage regulator with wall mounting from a trusted manufacturer. The active power of the unit is 350 W and the apparent power is 400 VA. It is connected to a single-phase network and operates with an input voltage in the range from 110 to 260 V. Provides a stabilization accuracy of 8%, which gives an output voltage of 202 to 238 V. It features a fairly fast response of 7 ms. Protection against short circuit, overheating and overvoltage, of course, in its place. The built-in voltmeter allows you to display the input and output voltage. A great way to protect your gas boiler from poor quality food for only 2700 rubles.

FAQ

Will the voltage regulator provide protection against lightning strikes in the line?
Yes. If a sudden voltage surge occurs from a lightning strike, which exceeds the operating range stabilizer voltages, it will simply turn off and at the same time turn off all electrical appliances that are powered through him.
