Uninterruptible power supply and safe operation of the boiler
Do you want to use your boiler safely? Then be sure to read the article to the end.
You are using or planning to install a solid fuel boiler. In most modern boilers, the combustion process is regulated by a control unit and a turbine, and the heating medium is pumped through the heating system by a circulation pump. They require mains power to operate220В. When the voltage in the sockets disappears, the circulation pump stops working, which can lead to boiling water in the boiler, which in turn can damage the entire heating system. And it's winter outside!
To prevent an accident, it is necessary to provide the circulation pump and boiler automation with a backup power supply. This problem can be solved by installinguninterruptible power supply (UPS).
Uninterruptible power supply - is an electronic device that monitors changes in the mains voltage and switches on the emergency power supply circuit from the battery(s) in the event of a mains voltage failure220Вor if the mains voltage goes beyond the permissible limits. When the voltage stabilizes, it switches the power to the mains and recharges the battery at the same time. Unlike computerUPS, UPS for the boiler does not have a built-in battery; the battery capacity is selected individually in each case, depending on the electrical power consumption of all boiler elements (circulation pump, automation, blower fan, etc.) and the time during which the boiler must be kept in autonomous mode.
Therefore, choosingUPS for the boiler and the battery for it, you need to know the answers to the following questions:
How much power does your boiler's electronics consume?
Energy consumption range of boilersAltep 120 - 350 W per hour (excluding the circulation pump power consumption to be added). This information can be found in the technical documentation for the boiler. The power depends on the value of this parameterUPSwhich is chosen with a margin (preferably 30%). The electrical power consumption can be found in the boiler technical documentation.
How long should the boiler operate in autonomous mode?
The battery life is determined by the capacity of the rechargeable battery connected to theUPSThe larger the capacity of the battery, the longer it will last. However, there are limitations imposed by the technical characteristics of the uninterruptible power supply itself: if the passportUPS the maximum battery capacity is indicated100 HourThis means that it simply cannot charge a large-capacity battery.
When choosingUPS for the boiler heating, you should pay attention to several important parameters:- The output voltage waveform of the uninterruptible power supply must be sinusoidal. If you focus on this characteristic, then the following should be suitableon-line or goodline-interactive UPS
- ТAlso, pay attention to the quality of the voltage in the network from which your home is powered. If there are large voltage drops in such a network, then an important characteristic when choosingUPS is the range of input voltage - the wider it is, the less often the uninterruptible power supply will switch to the battery, and, accordingly, the longer it will last. The service life of the battery directly depends on the number of charge-discharge cycles.
- We also advise you to pay attention toUPS has protection against deep discharge and overcharge of the accumulator battery, as each deep discharge of the battery reduces its capacity and leads to premature aging. So, use the boiler safely and ensure its autonomous operation!
