Modern gas boilers, which are used in industrial and residential premises, are volatile. But if there is no electric current in the network, they simply will not work. In this case, the house will be enveloped in cold weather, and inside the room a temperature will form that is unsuitable for human habitation.
Unfortunately, in Russia electric networks have a large length and high deterioration, so consumers quite often face the problem of an emergency shutdown. Improvements in this matter are not expected, and an inverter for a gas boiler can be used as an output.
Comparison of the main types of inverters: redundant UPS
Such uninterruptible power supplies are also called offline, they are used in conjunction 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 noiselessness in work, low cost and simplicity are important for you, then it is worth choosing such an inverter. However, it has some disadvantages, expressed in the long time switching to backup power from the main one, and in that the electric current is represented by successive pulses. Another minus is the lack of stabilization of the current in frequency and magnitude.
When to choose a line interactive inverter
Such an inverter for a gas boiler according to the principle of operation and composition is similar to the previous one, but has an element that stabilizes the voltage within certain limits. You can find models with stabilization of the frequency of the electric current. If time for switching to an additional mode is important for you, then it is worth purchasing 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 is more suitable than others.
Inverter selection: online device
When choosing an inverter for a gas boiler, you should pay attention to online devices, which are the most advanced in terms of quality and technical point of view. Such inverters are used where there is a need to obtain current with better parameters.
The main difference is the double conversion of current. Alternating current is first converted to direct, and then again to alternating current.
The main advantage of online devices is an instant switch to a backup power source from the main one, which is why the time parameter is almost zero. Among other things, the magnitude of the voltage and frequency of the current can be adjusted.
However, there are also disadvantages consisting in the release of thermal energy and an increased noise level. Gas boilers should be powered exclusively from an electric current of a sinusoidal shape. If we compare the inverter with other backup power sources, we can note their durability and reliability, low noise level and the absence of additional costs for many years of operation. Maintenance will only include battery care. An inverter for a gas boiler has many advantages, but its cost is quite acceptable.
How to choose an inverter
Before shopping, you must determine the power of the heating system and other estimated loads. You can find out this value empirically using special measuring tools. If there are none in your arsenal, you can just look into the passport of the boiler.
Before purchasing an inverter, you need to ask if it is capable of generating a sinusoidal voltage shape and performing double conversion. The device will almost instantly connect to the battery if the sensor detects a lack of current in the network. You can ask how much time the inverter will provide the system in battery support mode. The optimal period of operation is approximately 10 hours. However, it is better to focus on the conditions of the region. Sometimes it happens that a house is disconnected from electricity for more than a day. In this case, it is necessary to select an inverter with a battery reserve of at least 20 hours.
If you are thinking about how to choose an inverter for a gas boiler, then you need to consider that a car battery will not work for it. The difference lies in the charge-discharge characteristics, which are different for special batteries for heating equipment. In addition, experts advise buying batteries that are made using AGM technology. This recommendation is due to the fact that such devices last longer.
When installing the battery, do not place it close to the heating device, and if there are several, close to each other. Keep a 10 cm distance. To ensure full and stable operation, care must be taken to maintain a stable temperature in the range from +20 to +25 ° .
UPS fabrication
Doing an inverter for a gas boiler with your own hands is quite simple. To do this, you should purchase a battery charger, the battery itself and the converter. On the latter, there are only two terminals that should be connected by wire. Now the boiler plug must be plugged into an outlet on the inverter, on the last one you must press the “Enable” button, and the process will start. 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 do this also stationary by connecting the battery to the outlet.
Conclusion
Inverters for gas heating boilers, the comparison of which was given above, should be installed in stages. First, connect and then configure. The last step is testing. If you do not have enough knowledge in this area, then it is better to entrust these works to a specialist.
