For the reliable and long operation of any electrical equipment, the quality of the electrical voltage in the network is important. We can not influence the jumps in the electric system, but we can not save the equipment from them with the help of special equipment. Of course, you yourself decide whether you need a voltage regulator for a gas boiler , but all experts will unanimously say that it is simply necessary.
Types of voltage regulators
Relay type (digital) - inexpensive and not particularly reliable instruments. Approximately every 3-4 years you will have to change them because of burning contacts. By the way, the accuracy of the stabilization amplitude in them is also low.
On the servo motors , the output voltage is smoothly balanced, although they work slowly, which increases the probability of an accident.
Thyristor (electronic) voltage regulators for a gas boiler are the best instruments. They are durable, noiseless, high-precision, instantly react to voltage surges and align them, saving your expensive equipment.
Other criteria for selecting a voltage regulator for a gas boiler
To correctly choose a stabilizer for the boiler, you need to consider such parameters as:
- Electric power of the boiler . Typically, gas boilers at the inlet consume 100 to 200 watts. And since this value for different boilers is different, you need to clarify it on the passport and in accordance with these select a stabilizer. Thus it is necessary to multiply the figure in the passport by five and add another + 10% of the stock.
- Manufacturer . When choosing a stabilizer brand, do not look at the producing country, because in China too they do good technique. Rather, you need to pay attention not to geography, but to the range of products offered by this manufacturer. So, if the list of stabilizers in a wide power range, as well as intended not only for certain types of equipment - gas boilers, televisions, refrigerators - but for the whole house , this is a good sign. In addition, it is desirable to choose not new items, but time-tested brands.
- Specifications :
- response time - measured in milliseconds, and the lower this figure, the better;
- the reaction rate is in volts per second (B / sec), the higher the value, the better the device, because it can correct a higher voltage in a second;
- operating range at the input - max and min voltage values, which the device is able to equalize, and when exceeding these limits, the stabilizer simply turns off the boiler;
- operating temperature range - as a rule, such devices operate at + 5 ... + 40 ° C, and street devices require an additional casing to work in the frost;
- the number of correction levels is indicated in the relay models, the more of them, the more accurately the level of voltage is maintained, but the more expensive the device.
How to choose a voltage regulator for a domestic and foreign gas boiler?
Speaking specifically about brands and models, among domestic
From abroad only Italian instruments of the brand Orion are brought to us. There are also Belarusian stabilizers ZORD, assembled from Chinese spare parts.
The Baltic instruments are represented by the Latvian company "Resanta". There are several electromechanical and relay models. Directly for gas boilers are suitable two of them - Resant ACH - 500/1-EM and Resanta ACH - 1000/1-EM.
