How to choose a bespereboynik for the boiler?

Often in private homes and cottages, the heater is the only instrument for heating water and a source of heat. In order to avoid serious malfunctions, the boiler needs a special uninterruptible power supply or simply an uninterruptible power supply.

The purpose of a bespereboynik for the boiler is an ambulance in case of breakage or switching off the light. In fact, it is a spare power device used when the main current supply is disconnected. The device is necessary to provide electrical energy to the entire control system of the heating equipment, as well as the circulation pump and ventilation systems. Bespereboynik can work for a long time. Depending on the type of boiler, it is protected against low voltage mains and switching off the boiler, in addition, it protects the system from power surges.This device not only provides the heating system with electrical energy, but also improves its quality and contributes to providing the input voltage in the form of a sinusoid. Therefore, due to it, processors, electromagnetic valves and transformers operate normally.

Bespereboynik not solve all problems. He is unable to replace the generator, and also to work for a long time, since it charges longer than its discharge. However, in an emergency or other unforeseen situation, this equipment provides a constant voltage within the specified limits. He is able to give the accumulated energy as needed. Its design is designed for autonomy and is distinguished by a minimum of settings.

An uninterruptible power supply (UPS) consists of several units. These include an inverter that converts a constant voltage of 12 V to an alternating 220 V with a perfect sinusoidal shape, which is necessary for the normal operation of the boiler. In addition, it has a voltage regulator that levels the quality of the power supply. The implementation can be made in the form of two different blocks or separately the inverter and other devices.The power source in an emergency are batteries. The UPS works from them only when power is lost.

One of the characteristics of the UPS is an instantaneous switch to battery power. Usually, the connected equipment does not have time to disconnect. The package, in addition to the case and the batteries themselves, includes current transducers, switches, and a control chip.

The main characteristics that are important to the work are several criteria.

• Type of sine wave output voltage. It can be standard smooth and approximated, atypical for many devices, therefore, increasing their wear.
• Power consumption. Due to the high values ​​of current at start-up, the performance of the bespereboynik should be twice as high as the energy consumption of the boiler.
• The speed of transition to backup power batteries. The higher this figure, the longer the service life of the main equipment.
• Electric intensity. This criterion determines how long the device will work offline. Often, in order to increase capacity, an auxiliary external battery is connected to the uninterruptible power supply.
• Lifetime.Usually this parameter is subject to the use mode of the device.
• Spectrum of network input parameters. It depends on the acceptability of the voltage and its quality.
• Grounding This parameter is considered mandatory and has the name "through zero."

Usually, the standard period of work is determined by the method of testing an individual set of equipment. The cost of the device is subject to the battery capacity (number of hours of operation), additional functions, as well as compliance of the output current parameters with existing standards.

To date, the developed types of uninterruptible power supplies for boilers can be classified according to the method of operation.

Based on this, they may be as follows:

• continuous;
• line-interactive;
• reserve.

To understand their difference, it is worth noting briefly how each type works and what its features are.

An off-line type of backup unit is considered to be a kind of intermediary, since it transmits current and voltage without changing their characteristics at the entrance to the unit. If a power outage occurs or it goes beyond the set values, the UPS transfers to battery operation. Typically, the battery capacity of these devices is 5-10 Ah.Usually this is enough for the boiler to work after switching off the main power supply for up to half an hour. The main criterion for the purchase of this type of device is the power supply in case of emergency shutdown. They are bought in order to have time to properly turn off the equipment after the boiler has stopped.

One of the advantages of this type of device is the noiseless operation., high efficiency, and also reasonable cost. The disadvantages are the insignificant battery capacity, slow switching to emergency operation and the inability to correct voltage indicators.

These units are considered better than previous ones. In addition to the battery, they are usually equipped with a voltage regulator. Due to this feature, they provide 220 V output voltage. The price of such devices is higher.However, they can analyze the type of sinusoid, as well as perform a power switch in cases where its appearance is distorted by more than 5%.

The main advantage of these devices is the minimum switching interval from the network mode.which is about 2–10 m • s. Due to them, it is possible to stabilize the voltage without the battery. The disadvantage of this type of instrument is the fact that they cannot change its shape. By themselves, such devices are structurally more complex than backup analogs. In addition to the fact that they have high output power, they are often connected to quite capacious external batteries. Unfortunately, these devices are not able to adjust the frequency of the current, although they differ in high efficiency during operation from the main (mains) power. Their connection at the right time practically does not affect the operation of the system equipment.

This category includes so-called bespereboniki heating on-line. It does not matter if there is a voltage at the input or not, devices of this type are always powered by an existing battery. The value of the electrical outlet network at the devices of this type does not depend on the input indicators.Power is provided through a two-stage energy conversion. Initially, the input voltage level is reduced, the alternating current is rectified. Thus, the battery is recharged.

The scheme of devices of continuous type multicomponent. From the point of view of efficiency, it is justified only with high-power equipment, as well as the capacity of batteries. In the process of returning electricity, the process is reversed to the first stage. There is a removal of electrical energy from the contacts, the current becomes variable, the voltage increases and enters the output of the UPS. In fact, the system is constantly working offline, with the stability of the parameters. Therefore, in this case, the voltage spikes do not matter, the deformation of the sinusoid is not fearless.

Of the advantages of this type of equipment, it is worth noting the stability of the system during an emergency power outage. Devices of this type are protected from any voltage surges. They can be connected to the gas generator, if it is necessary to replenish the charge. In addition, the user has the ability to adjust the parameters of the output voltage.The disadvantages of such UPSs are noise and heat in the process of the fan. In addition, such devices are characterized by low efficiency, as well as high cost. Their price is 2 times more than analogs of linear-interactive type.

Today, in the modern market, the buyer’s attention has been offered a lot of bespereboynik models for boilers. Among the various models worth noting products of Russian companies. For example, the Energy Energy PN-1000 UPS model with the 75Ah battery of the Energy brand is noteworthy. It has protection against overloads, short circuits, as well as overheating and complete discharge of the battery. The sinusoid of this device at the output has no distortion due to the existing relay stabilizer inside the device.

The budget version of the bespereboynik is the device of the domestic manufacturer Ecovolt ECO 612E 800BA. It is distinguished by the ability to display parameters on an existing display. The user can see all the information about the system and its malfunction. The battery is charged quickly, either completely or partially.When the battery is completely discharged, the user receives an audible alert. The disadvantage of such a device is a characteristic hum during its operation.

The Inelt Intelligent 500LT2 model has quite good characteristics. It is a powerful charger with the ability to quickly restore charge. And it also has a large input voltage range (165-275 B). Under normal conditions, this uninterrupted power supply is able to work up to 55 minutes. The maximum capacity of its battery is 250 Ah.

Model Helior Sigma 2 KSL produced in China. The device is characterized by high-quality assembly and reliability of work, as evidenced by numerous reviews of real buyers. Unlike other varieties, it is characterized by a low noise level and minimal energy consumption. And it also has a convenient LCD screen that informs the user about the operation of the system. Its only drawback is the inaccuracy of indicating the degree of discharge of the battery.

The choice of a bespereboynik depends on a number of factors. First of all, when purchasing, it is necessary to take into account the power of the heating unit.In addition, we must not forget about the functionality of the heating system, because it will depend on the type of device. Need to calculate the power of the device. To do this, it is necessary to add the power of all devices that are planned to be used for power, including pumps and automation.

Since the current values ​​at start can exceed initial values, the consumed power level should be tripled. The resulting total is multiplied by 1.3 and get the value of the required power of the purchased device. In addition, before buying, you need to accurately calculate the required battery life in a stand-alone mode. From this will depend on the number of batteries. Their type may be different, but for the boilers it is impossible to buy batteries of automobile starter type. In addition to the minimum load, they very quickly fail, and most of all are afraid of complete discharge.

It is important to consider not only active, but also full power and limits of the working voltage limits. Well, if you can connect external batteries to the device. This is especially important when there are doubts that the built-in resource will not be enough.

It is better if the operating voltage threshold is low, and the device is equipped with a current stabilizer. If the device does not have a smooth sine wave, it will not work stably. This may cause a systematic inadvertent on and off of the device. When the boiler is not equipped with an automated system of switching on after the mains supply, the devices with a long period of time are not suitable for switching. It is better to purchase options with zero switching time for battery resources with double conversion, as well as a stabilization function. Although they are more expensive, however, they are characterized by greater protection of the components of the heating system.

It is better to make a purchase in a proven store that has positive customer reviews. This will minimize the risk of buying low-quality goods. In addition, in the process of choosing a device, you should ask the seller for a certificate of quality and compliance with the established regulations, which will confirm the seriousness of the brand.
