Modern volatile gas boilers of heating are equipped with highly sensitive electronics which reacts to voltage surges in the power supply network. In this case the equipment can quickly fail. That it it did not happen, recommended to choose the stabilizer for heating boiler. When choosing are guided by several criteria: type, power, device cost.
Stabilizer type
Functions of any stabilizer consist in the following. The device reacts to the size of line voltage and corrects it before giving of current in the electric device. If indicators are much higher than admissible, the protection which is breaking off electrical circuit works. When tension returns to norm, operation of the boiler will be resumed.
The stabilizers for boilers differing in many parameters enter the range of shops. Devices can be hinged, floor, single-phase and three-phase, working from direct and alternating current.
On way of switching of windings allocate the following types of stabilizers:
- Electromechanical (with the servo actuator). The device is similar to the automobile transformer. Pluses of the electromechanical stabilizer: small dimensions, smooth voltage regulation, maintaining working capacity at voltage surges.
- Electronic (relay). The relay is provided in design. Devices cost not much, are rather reliable. They do not demand service, quickly switch at fluctuations of entrance signal.
- Contain simistor and the relay. Designs differ in durability, in them parts which would wear out in the course of mechanical operation. Units work silently, ensure trouble-free operation of boiler. Multilevel overcurrent protection, short circuits, excessively high or low tension logs in.
- Have the thyristor keys influencing sinusoidal form of current. Operation of the device is regulated by the processor. Such models are durable, silent, immediately react to voltage variation.
Power
Upon purchase be defined what power there has to be stabilizer. Consider in the sum indicators for gas boiler and the pump. Also it is necessary to know that when the pump is started, the consumed current exceeds nominal size almost by 3 times.
Study the technical characteristics of the equipment specified in the passport of the unit. When determining necessary size it is necessary to increase the power of loading by 5. Increase the received number by 1.3 (protection coefficient). Stabilizer power size will turn out.
Range of permissible values of tension
Range of permissible values of tension on entrance – one of the main characteristics of stabilizers. Parameter shows with what indicators of tension the device is capable to cope and transform them to the value close to 220 V.
The more range, the better. It is recommended to choose the stabilizer, considering reserve. I.e. if tension falls, we will tell up to 180 V, pay attention to devices on lower limit 160 V. Takzhe decide also on the upper bound of range.
