How to choose an inverter for a gas boiler? Inverter for gas boiler own hands

Modern gas boilers, which are used in industrial and residential buildings, are volatile. But if there is no current in the network, they simply will not work. In this case, the house will be covered with cold, and inside the room a temperature is formed, unsuitable for human habitation.

Unfortunately, in Russia, electrical networks have a large length and high wear and tear, so consumers often face the problem of emergency shutdown. Improvements in this matter are not expected, and as an output it is possible to use an inverter for a gas boiler.

Comparison of the main types of inverters: standby UPS

Such uninterruptible power supplies are also called off-line, they are used together with gas boilers, personal computers and household appliances. The principle of their work is to connect the batteries when the voltage in the network drops or disappears. If you are interested in noiselessness in your work, low cost and simplicity, then it is worth choosing such an inverter. However, it has some drawbacks, expressed in the long time of switching to backup power from the main one, and that the electric current is represented by successive pulses. Another disadvantage is the absence of the possibility of stabilizing the current in frequency and magnitude.

When to choose a line interactive inverter

Such an inverter for a gas boiler is similar in principle to the previous one, but has an element that stabilizes the voltage within certain limits. One can meet models with the stabilization of the frequency of electric current. If it is important for you to switch to an additional mode, then it is worthwhile to purchase online-interactive. On sale you can find devices of this type that produce an electric current of a sinusoidal shape. For home use, such a device fits more than others.

Inverter selection: device online

When choosing an inverter for a gas boiler, it is necessary to pay attention to online devices, which are the most perfect in terms of quality characteristics and from a technical point of view. Such inverters are used where there is a need for obtaining a current with better parameters.

In the role of the main difference is the double conversion of the current. The alternating current is first converted into a constant current, and then again into an alternating current.

The main advantage of online devices is the instantaneous transition to a backup power source from the main, which is why the time parameter is almost zero. Among other things, the magnitude of the voltage and the frequency of the current can be adjusted.

However, there are also drawbacks, consisting in the allocation of thermal energy and increased noise level. Gas boilers should only be powered by an electric current of a sinusoidal shape. If you compare the inverter with other sources of backup power, you can note their durability and reliability, low noise and no additional costs for many years of operation. Maintenance will consist only in the care of batteries. The inverter for a gas boiler has many advantages, but its cost is quite acceptable.

How to choose an inverter

Before visiting the store, you need to determine the power of the heating system and other expected loads. You can find this value by experiment, using special measuring tools. If those in your arsenal were not, then you can just look in the passport of the boiler.

Before buying an inverter, you need to ask whether it is able to produce a sinusoidal voltage waveform and perform a double conversion. The device will connect to the battery almost instantly, if the sensor detects the absence of current in the network. You can ask how much time the inverter will provide the system in the battery support mode. The optimum period of operation is approximately 10 hours. However, it is better to focus on the conditions of the region. Sometimes it happens that the house is disconnected from electricity more than a day. In this case, it is necessary to select an inverter with a battery reserve for at least 20 hours.

If you are thinking about the question of how to choose an inverter for a gas boiler, you have to take into account that the car battery does not fit it. The difference lies in the charge-discharge characteristics, which are different for special heating equipment batteries. In addition, experts advise buying batteries that are made using AGM technology. This recommendation is due to the fact that these devices last longer.

When installing the battery, do not place it close to the heater, but if there are several, close to each other. A 10-cm distance should be maintained. To ensure full and stable operation it is necessary to take care of keeping a stable temperature in the range from +20 to +25 ° С.

UPS manufacturing

The inverter for a gas boiler with its own hands is quite simple. To do this, you need to buy a battery charger, the battery itself and a converter. On the latter there are only two terminals, which should be connected with a wire. Now the boiler plug must be plugged into an inverter socket, the last one should be pressed the "Enable" button and the process will be started. Inverters for gas heating boilers can be recharged as soon as electricity appears. To do this, the charger must be connected to the battery. You can also do this permanently by plugging in the battery pack.

Conclusion

Inverters for gas-fired heating boilers, the comparison of which was given above, should be installed step-by-step. First, you connect and then configure. At the last stage - testing. If you do not have sufficient knowledge in this area, then it is better to entrust these data to a specialist.
