What kind of boilers can be connected to the battery during a power outage?

Hello. Here, the question is rather not what type of boiler can be connected, but how to choose an uninterruptible power supply - almost any boiler can be connected to the battery. If you have frequent and severe power outages, then you need a UPS with a stabilizer. I do not think that some models in this regard are more “stable” than others.

Therefore, put the boiler that you selected and connect the UPS to it. Here's what to consider when choosing them:

1. Type of device:

- Linear. The boiler installation is powered from the network, but during a power outage, the converter from the battery is activated. The disadvantages of such a device - it quickly wears out the batteries, does not equalize the voltage, however, it is quite possible to equip them;
- Line-interactive. Here the situation is better, there is a filter and a stabilizer, it turns on only when it falls below a certain voltage mark. Minus - a small delay switching relays;
- Online. A double converter, the sine wave is correct, but the device is expensive.

2. Power. Starting currents can significantly exceed the rating, so it is important here to choose the right power, taking into account all devices.

3. Opening hours. The larger the battery capacity, the longer it holds.

4. Type of battery. It is unacceptable to use acid-lead models, AGM has a small charge / discharge cycle, gel ones have a gel electrolyte, are quite durable and are resistant to a full discharge (in general, the most suitable option).

5. The output signal. A common mistake is to connect any type of battery indiscriminately to boilers of this type, for example, from a computer that has an approximated sinusoid. What is good for a computer is not suitable for a heating device and will degrade its performance. A pure sine wave is needed for the boiler.

I can’t tell you about brands, from personal experience, but they really praise it in conjunction with the work of popular brands of boilers - “Rucelf” (Rouself) and “Energy”.However, here the choice is ambiguous, all ratings are completely different and are based on the principle "the cuckoo praises the cock ..." or "what I sell, I’m rating it."

Connect the installation must a professional. Also, when choosing a UPS, be sure to consult with the seller in addition, check all the parameters and features of connecting the device.
