The work of gas boilers largely depends on theUninterrupted and high-quality power supply. Due to power surges and frequent power outages, boiler equipment can quickly fail.
Therefore, a reliable uninterruptible power supply is needed for the boiler.
Uninterruptible power supplies
Uninterruptible power supplies are needed to create a permanent electrical connection. They allow the gas boiler to continue operating when the electricity is cut off.
In comparison with gasoline and diesel electric generators, uninterruptible power supplies have the following advantages:
- higher coefficient of reliability-
- simple installation and connection-
- more time between failures-
- Noiseless operation-
- there is no need for constant maintenance and replacement of consumables.
Perpetual workers fulfill a number of conditions necessaryFor high-quality power supply of circulating pumps and electronic block of gas boiler. These conditions include: sinusoidal voltage waveform, high accuracy of voltage and frequency values, filtering properties, protection from deep discharge of batteries, wide range of input voltage.
Types of UPS for gas boilers
There are three types of sources for joint operation with gas boilers: linear, linear-interactive, double conversion UPS.
The simplest model is linearuninterruptable power source. The voltage at the input and output of the device does not change, since in its design there are no voltage regulators for gas boilers. Such a source has the ability to disconnect from the mains while switching to battery power.
The line-interactive UPS has a simpleVoltage regulator. If you connect an external battery, such a source will ensure the operation of the gas boiler without connecting to the electrical network for up to ten hours. The output of the UPS produces a sinusoidal signal, with the characteristics of 50 hertz and 220V.
Uninterruptible Power Supply DualConversion in addition to backup power provides voltage stabilization. In addition to the possibility of stable operation of the boiler at a voltage of 110-300V and filtering interference, it is possible to connect a gasoline generator.
Accumulators for uninterruptible power supplies
You can use uninterruptible power suppliesConnect several batteries, thus increasing the duration of its battery life. Thus it is necessary to make sure that all the batteries in the battery are of the same capacity and have the same level of charge. Otherwise they will be unevenly discharged and it will not be possible to achieve a long period of autonomous work.
UPS batteries can be connected in series andparallel. If you turn on sequentially, the battery capacity does not change, but the voltage is added up. With parallel connection, the voltage does not change, and the capacity of the battery increases proportionally.
Sometimes for the sake of economy together with the uninterruptedUse car batteries. Doing this is not necessary, because incorrect connection of the batteries will lead to an uninterruptible power supply failure, in which case it will not be replaced under warranty. The most suitable option - sealed batteries, which are designed specifically for uninterruptible power supplies.
After connecting several batteries, arrange them so that an air gap forms between them. Otherwise they will additionally heat up from each other.
Batteries are quickly discharged in heat, soThey should not be near heat sources. Low temperature also quickly discharges them, so the best option is to keep them at room temperature.
How to choose an uninterruptible power supply
Choosing an uninterruptible for a gas boiler,It is necessary to pay attention to the time of necessary autonomy and power consumption. In this case, we mean the electric power of the circulation pumps and the automation of the boiler. For pumps are characterized by high starting currents, because of this their power must be multiplied by three. The boiler output can be specified in the product data sheet.
For a summer residence and at home a small wall-type fixing uninterruptible power supply will do.
In addition, decide on the necessary timeAutonomy, it depends on the capacity of the batteries and the power of the load. With high capacity and lower power of load connections, longer autonomy time. As already mentioned above, the required battery life is provided by connecting a different number of batteries. But this does not mean that it is necessary to collect the system on the principle "it works longer - it works better", as its cost increases with the increase in the number of rechargeable batteries. Collect the kit, starting from the work of your network. If it is characterized by short trips, you should not overpay and collect a system that will provide an autonomous electric power for a day.
