Stabilizer for a heating boiler: choice, description, characteristics

Modern boilers are high-tech equipment, the functioning of which is controlled by electronics. She, in turn, is very demanding on power. It is demanding both for the magnitude of the voltage, for its shape: it must be a sinusoid and 220 V with a certain error of 5%.

The need to use a stabilizer

As practice shows, a huge part of the breakdowns of gas boilers is connected with the differences in the network. For this reason, experts recommend the addition of a stabilizer or uninterruptible power supply. Peak breakages occur in the summer or late spring. There are two reasons for this, one of them is expressed in the neighbors, who started repair or construction, the other - in summer thunderstorms. If you somehow can predict the approach of a thunderstorm, then it's simply impossible to find out when someone will use a Bulgarian, a welding machine or a sawmill. Therefore, it is recommended to protect expensive equipment in advance.

For reference

The stabilizer for the heating boiler , the price of which will be mentioned below, can be used to protect only the equipment, in this case the device must be connected to the network, and the voltage must be applied to the boiler. If the stabilizer is installed on the house or apartment, then for the boiler equipment, these devices will be needed only if the unit is powered by an electric motor unit. This includes a washing machine or refrigerator. Jumps while turning off and on such devices will negatively affect the automation of the equipment.

Description of different types of stabilizers and features of choice

If you want to choose a stabilizer for a heating boiler, you should get acquainted with the basic types of such devices. They can be electromechanical, relay or electronic. The second version is also called digital, but electronic ones are known as thyristors. At the heart of such devices is an autotransformer. In electronic and relay, it has windings in the amount of 4 to 20. By disconnecting and connecting, you can align the input voltage.

The accuracy of the stabilization will depend on the number of windings. Thus, the more of them, the less is the step of correction. This indicates that the voltage will be maintained with minimal deviation. The difference between electronic and relay models is in the switches used. As can be understood from the name, these are thyristors and relays. The construction scheme is similar, but the response time of the elements is different. Thyristors are faster, this indicates that electronic models have better indicators.

Advice from a specialist

With the help of relay stabilizers it is possible to provide accuracy in the range from 5 to 8%. As for electronic, the accuracy in this case can vary from 2 to 3%. When choosing a stabilizer for a heating boiler that operates on gas, an electronic version should be preferred. As a positive feature is the low noise level at work, but the minus is the high cost.

Characteristics of electromechanical and relay stabilizers

When choosing a stabilizer for a heating boiler, you should familiarize yourself with the basic characteristics of the models. For example, electromechanics are ready to last from 1 to 5 years, the manufacturer usually gives a guarantee for one year. The range of voltages can vary from 150 to 250. Such stabilizers should be serviced once a year, and the reaction time is 10 V per second. When choosing an electromechanical stabilizer for a heating boiler, you must take into account that it provides a twenty percent protection against jumps, and the accuracy of stabilization varies between 2 and 3%. The cost of 1 kW in the end can vary from 900 to 1600 rubles.

If we compare with relay regulators, then we can say that they will last longer. The minimum period of operation is 3 years, but the guarantee from the manufacturer remains the same. Such voltage regulators for heating boilers have a range of voltages ranging from 120 to 260, the device does not require maintenance, and the reaction time is 50 V per second. By purchasing such an aggregate, you can count on fifty percent protection, but the accuracy of stabilization can vary from 5 to 8%. As a result, the cost of 1 kW will be somewhat less, in comparison with electromechanical devices, this range varies from 700 to 1500 rubles.

From the above, it can be concluded that electronic voltage regulators for heating boilers are preferable for gas equipment. Such devices are more expensive, but the price pays off. And if you already have a relay stabilizer, then it must be installed on another unit or supplemented with an uninterruptible power supply.

Recommendations for choosing a stabilizer

With the version of the stabilizer we have already figured out, now it is necessary to determine the power. The power of the boiler equipment can be found in the passport, usually it varies from 100 to 200 W, but this value is average. In those moments when the device turns on or off, this parameter can exceed the initial value by 5 times. Therefore, the figure you could find in the passport must be multiplied by 5, adding a stock of 10%. This will determine the required power.

Now you can choose a brand, you should pay attention to the country of origin. For example, China produces good products. It is also important to take into account the range of capacities. If it is wide enough, then this feature can be called good, because technology is worked out. Do not buy new items, as for working out a normal model it takes years.

Cost for stabilizers

If you want to purchase a stabilizer for a heating boiler, Teplocom can be an excellent solution. Model ST-555 can be purchased for 3500 rubles. The power is 555 VA. This stabilizer, according to the manufacturer, is sufficiently reliable and simple. It is designed for automation of boilers and heating systems. With its help, it is possible to obtain an equalized output voltage for values ranging from 200 to 240 V.

As another model, you can consider the stabilizer for the heating boiler Hunter 440. It can be purchased for 5500 rubles. The equipment is a single-phase device with a rated power of 0.350 kW. The range of input voltages varies from 120 to 260 V. The operating frequency is 50 Hz, the efficiency reaches 97%. The error can be 8%. Operation is possible at a relative humidity of not more than 80%. This stabilizer for a gas heating boiler can be operated at a temperature of +5 to +40 ° C.
