Whatever source you choose, it will be of high quality and with the maximum degree of reliability. But the popular Resanta brand is
not the best choice. As practice shows, its UPSs are not reliable enough to work with the sensitive electronics of a gas boiler.

Purpose of UPS for boilers

When the power supply in the city is turned off, the collective heating system remains operational. Some owners install autonomous equipment. However, even in this case, you can count on the problems being resolved fairly quickly by repair services.

Typical problems of suburban households :

• voltage drops in the network;
• slow elimination of emergency situations.

Using an uninterruptible power supply for a gas boiler, the following tasks can be solved::

• ensure operation of the equipment when the standard 220V power supply is disconnected;
• maintain normal voltage levels;
• prevent software errors and damage to electronic components.

The UPS for gas boilers performs its functions autonomously, without careful control by the user. The service life of modern models is 15-20 years or more, which should be taken into account when calculating investments in a project.

The exception is rechargeable batteries, which are replaced as their service life expires. As a rule, such operations are performed after 3-4 years of intensive use.

Power

How to correctly calculate the power of a UPS?
There is a common misconception that the power of the UPS should be the same as the total power of all boiler modules. This is wrong. Starting currents are much higher than linear ones. For example, if you have a pump with a nominal rating of 300 watts, then at the time of startup it will consume approximately 500 watts. Such a jump appears very quickly and disappears just as quickly, but if the uninterruptible power supply does not have an appropriate reserve, this will negatively affect both its operation and the service life of the boiler’s electronic modules. Some experts advise taking devices whose power is three times higher than the rated requirements of the boiler, but this is too much. Doubling the numbers is quite enough here.

Simply put, if your gas boiler consumes 1 kilowatt, then the UPS should be 2 kilowatts or a little more, but not less.

15 best uninterruptible power supplies (UPS)

Types of uninterruptible power supplies

UPS manufacturers produce devices for any financial budget, but the more expensive it is, the higher its functionality and battery life.

Based on their operating principle, UPSs can be divided into three main categories: continuous (on-line type), line-interactive and backup (off-line type). Each type of uninterruptible power supply will be discussed in more detail below.

Reserve

If there is electricity in the network, a backup or off-line uninterruptible power supply plays the role of an intermediary, transmitting voltage and current with the same characteristics that are available at the input to the device.

Only when there is a power outage or its parameters go beyond the programmed range, the UPS switches the connected equipment to battery power.

The control elements of inexpensive backup uninterruptible power supply units are usually limited to one button, various combinations of presses on which allow you to adjust the operation of the device.

Backup uninterruptible power supplies are usually equipped with batteries with a capacity of 5-10 Ah, which are sufficient for continuous operation of the boiler for 10-30 minutes.

Their main functions are to prevent instant stoppage of heating equipment and provide time for its correct manual stop.

The advantages of off-line UPS are:

• No noise.
• High efficiency when powered from the mains.
• Low price.

Disadvantages of off-line uninterruptible power supply systems:

• Switching time to battery is 4-12 m.
• Inability to adjust voltage and current characteristics.
• Operating from a gas generator is dangerous for the boiler because the sinusoid parameters are not maintained.
• Small battery capacity.

Many models of backup uninterruptible power supply systems require the installation of external batteries, due to which their battery life can be increased. But even with a powerful battery, they will remain just switches for powering the boiler from mains to autonomous.

Linear interactive

Uninterruptible power supply systems of the linear-interactive type are more advanced than backup ones. In addition to the battery, these devices have voltage stabilizers, which allows them to provide 220 V output.

More expensive models are capable of analyzing the type of sinusoid and switching power to batteries when it is distorted by more than 5-10%. Such IBS are unable to correct the shape of the sinusoid when operating from the mains.

Controlling a line-interactive UPS is more complex. It usually allows you to set the limits of the input voltage range and set the delay time for turning on the connected equipment.

Line-interactive models with high output power are often installed at the entrance to the electrical wiring of the house. Usually they are connected to capacious external batteries.

The advantages of line-interactive UPS are as follows::

• A short interval of switching to offline mode is 2-10 ms, which practically does not affect the operation of the connected equipment.
• High efficiency when powered from the mains.
• Possibility of voltage stabilization even without a battery.

Disadvantages of linear-interactive uninterruptible power supply systems:

• Inability to influence the shape of the sine wave when powered from the mains.
• Capacity is limited to 5 kVA.
• No current frequency adjustment.

Line-interactive UPSs are purchased more often than backup ones, because they are additionally equipped with a voltage stabilizer, which allows heating equipment to operate more correctly.

Continuous

The output parameters of the electrical network for continuous (on-line) uninterruptible power supplies do not depend on their input characteristics. Connected equipment is always powered by battery, regardless of input voltage. This is achieved by converting electricity in two stages.

First, the incoming voltage is reduced, the alternating current is rectified, and the electrical energy is used to recharge the battery.

Continuous UPSs have an expensive multi-component circuit, which is economically justified only with high power of the connected equipment and corresponding battery capacity.

When electricity is released, the reverse process occurs. Electricity is removed from the battery contacts, the current is converted to alternating current, the voltage increases and is supplied to the output of the uninterruptible power supply.

As a result, the connected equipment operates in a completely autonomous mode with stable electrical parameters. It is not afraid of power surges, sine wave distortions and even lightning strikes. External factors can damage the UPS, but not the gas water heater or floor-standing boiler connected to it.

Advantages of continuous uninterruptible power supply:

• During a power outage, power to connected devices is not interrupted.
• Stable voltage and frequency parameters, correct sinusoid, which is especially important when connecting a gas boiler.
• Protection against unexpected voltage increases.
• Hassle-free connection to a gas generator to replenish the charge.
• Possibility of adjusting the output voltage.

The main disadvantages of on-line uninterruptible power supply systems:

• Increased noise and heat generation during fan operation.
• Low efficiency (80-94%)
• The cost of continuous uninterruptible power supply systems is two to three times higher than the price of linear-interactive models.

The advantages of on-line UPS are obvious. These uninterruptible power supplies are quite expensive, but provide the highest possible electrical protection for a gas boiler. When you connect a high-capacity battery to them, you don’t have to worry about the normal operation of your heating equipment even during a power outage.

How to choose and what to pay attention to?

When choosing an uninterruptible system, it is important to evaluate the following parameters:

1. Power . The performance of the device depends on the power consumption. It is important to know that pumps require significant starting current.
2. Battery life . The indicator is calculated based on battery capacity and load power. The larger the battery capacity and the lower the load, the longer the device runs on battery power.
3. Voltage . Voltage surges have a bad effect on boiler electronics.

NOTE!

The UPS eliminates the possibility of device failure.

Interactive UPS Energy Garant 500

The percentage of error in the stabilized output voltage is a little high, but this is stated in the technical specifications. It is quite good for power supply of household devices. The battery charges without overcharging and switches to inverter mode without interrupting the voltage supply to the load. Nothing gets hot, the coolers are not noisy.

UPS RESANTA UBP-1000

This device is equipped with an electronic stabilization system. Therefore, here the relays do not click to switch windings. Accordingly, the output is a cleaner and smoother sinusoid. For measuring equipment, this operating mode is especially important. Although the output power is not high, it is quite enough for our equipment. I was looking for an uninterruptible power supply and ended up in this store, and I’m glad I found it. I chose an uninterruptible power supply (at first it was different, in consultation with the manager I settled on this model, special thanks to the seller, a person who knows his product), completed the purchase, within half an hour a very friendly manager of the online store contacted me to confirm the order and discuss the method of delivery and payment . The goods were delivered the next day safe and sound. Delivery works with a bang, I was also pleased with the payment after receiving the goods by the courier. I will be visiting this store in the future

I really liked the device. I am writing a review after three months. It is powered by a Protherm 40 Klo gas boiler and two circulation pumps. It switches to the battery instantly, nothing even happens to the boiler. The display is informative. Quiet. The fan does not drum. The battery charges 10 amperes, which is good since for some batteries this is the minimum value. Works with AGM 100A/h. In general, I'm satisfied.

The device itself attracted me with its price and characteristics. chased the cheapness. It would be better to overpay and take something else. I unpacked it for the first time, read the instructions for gifted people, plugged it into the network and there was no signal, it turned on and went out. I'm going to service. strange things started happening there, such as we can’t accept a case not covered by warranty. he had a melted network cable. Yes, and when I turned it on, I wasn’t convinced that I had taken the pig in a poke. Well, naturally the gimmick began to spin, saying it was your fault. I’m on mine, and a koekaker from the service department named Ilya is on mine, if he’s reading this truthful review now. draw the right conclusion Ilya. so as not to lose clients from your office called slay.ru, in the end, I returned this miracle device to them after some more time of proof that it was not my fault that the device was complete G.

We installed a boiler to heat a country house, and bought this device to go with it. The voltage in the network fluctuates, especially noticeably in the evenings - there’s no way without a stabilizer, and a UPS won’t hurt. The installer promised that the boiler would operate for three hours without recharging using the UPS. I didn’t lie, they checked. When you know for sure that you will not be left without heat in the event of a power outage, it’s calmer. The device has been in service for a year and a half without any complaints. I believe that during this time he has already managed to earn back every ruble spent on him. It does not take up much space, does not overheat and is not very noisy. It charges itself from the network.

After two months of operation it burned out and stopped switching modes. When opened, it turned out that the gearbox had burned out. Attached photo. Unfortunately, I didn’t take a photo from the back of the board; it looks much worse there. Traces of melting there are more extensive. Also depressing is the fact that there are burn marks on the side cover of the case. There is no insulation in areas adjacent to the body. In general, I’m extremely surprised to see something like this in a breaker/stabilizer, as if the appropriate fuses were not provided. I consider this effect of the operation of such devices unacceptable. The included batteries were Delta gel ones. The kit was used for the Wissman Vitodens 200 gas boiler.

IPPON Back Power Pro II Euro 650

With an overload of 110% and up to this figure: it will work for five minutes on mains power, and five seconds on battery power. If an overload of more than 120% is allowed, it will immediately shut down. Control of input and output voltage. UPS loading control and battery condition monitoring. All this information is displayed on the screen. Fully loaded. Almost. A 350-watt computer at its peak load. And - when switching to battery power, 1 minute of battery life. Not a little. The price tag suits me, there is passive cooling in the case. Under load and simultaneous operation from batteries, the temperature is ok. Both sockets are deep, with diagonal connection of equipment (L-shaped plugs will fit in without problems). Normas.

APC by Schneider Electric Smart-UPS SMT1500I

I bought it for home to power video surveillance, but also connected a PC, TV, NAS. As a result, when devices operate simultaneously, there is practically no power reserve; it was necessary to consider older models. I inserted a monitoring network card into the UPS (purchased separately). The Synology NAS connected to the UPS without any problems and began shutting down processes when switching to batteries. It sits in the closet, doesn’t heat up, but something “gurgles” inside every ~10 seconds. When I stood under the table, this sound was a little annoying. In the network card settings, I turned off the squeak from switching to batteries, and configured sending notifications to personal email. At work we also use APC UPS, but mainly of the rack type, they usually last about 10 years, I expect the same result from the new model.

Interactive UPS Powercom RAPTOR RPT-2000AP

Advantages: + inside there are 2 batteries to increase power and increase operating time + turns off on its own after the power is turned off and you turn off the computer + There is a voltage stabilizer, although simple, it is there, keeps the voltage from 200 to 230 at the output when the input is from 170 to 260 (lower down by 30 volts or increase up by 30 volts). Disadvantages: - the heatsinks on the board get very hot, the first UPS (the same one) burned out because of this, the board was replaced under warranty and I now installed an additional constant fan for airflow. — the original fan only works if it is running on battery power or there is a heavy load on the UPS, because of this the board overheats and we had to install an extra fan. — the battery is constantly not recharged due to low voltage at the terminals, approximately 26 volts at the terminals constantly, this is approximately 13 volts per battery. The batteries are charged to approximately 40-50%, not higher. To charge normally you need to supply 14 volts. As soon as the mains voltage disappears, after 5 seconds the battery charge drops to 40-50%, this can be seen from the installed software on the computer. - there is no declared 2000 VA, this is a marketing ploy. It holds the 5 min maximum of a simple PC with a consumption of 200 VA. Although the box says it should last up to 30 minutes. It doesn't hold up well precisely because of the inability to charge the battery completely. — the built-in cooler for cooling is bad, it is crooked and has terrible beating when rotating. — the power button is crooked, the contact in it is bad and buggy. To turn the UPS button on and off, you need to hold it for a few seconds, because... bad contact switching on switching off is buggy and goes to the test itself. Test itself with a short press of the button. — the batteries are located right next to a hot transformer, if you don’t put a gasket so that the batteries don’t get hot, then they will fail ahead of time. Comment: General impression: At the time of purchase, there was nothing better in terms of characteristics; in principle, the computer, which consumes approximately 200 VA of power, copes with its task for about 5 minutes. I basically have enough time to turn off the computer. The funny thing is that they don’t fully charge the battery, they did it this way specifically to extend the life of these batteries. If you plan to buy, open the case and place a gasket between the batteries and the transformer, and also an additional fan so that the board does not die from overheating.

BASTION Teplocom-1000

Advantages: Complete absence of any consequences for consumer devices from turning off the electricity. It all depends only on the capacity of the battery that you pair with the UPS. The output voltage fluctuates in the range of 220-221V (measured with a conventional tester). Disadvantages: There are not enough two pairs of battery terminals to connect everything right away. I had to go to the market separately. This shortcoming was voiced by the Deputy. Those. Directors, because It’s not good for a device that costs 20 kilo rubles to chase its owner after every little thing. All other wires and small items are present. The metal case, the design of which has probably not changed for 30 years, evokes an unhealthy nostalgia for the USSR, but in fairness it must be admitted that this is not the main thing and does not affect the functionality. Comment: I checked for a blackout in the network - as expected, I was glad to see that the light didn’t even blink. As a result, having selected a pair of batteries, the capacity of which will be sufficient for uninterrupted operation for a time equal to the average power outage interval in your region, you solve for yourself all the hemorrhoids with the operation of modern gas boilers and pumps for them. The old school of the Soviet defense industry knows a lot about serious equipment)

Battery charging time

How long does it take for the battery to be fully charged from the mains?
The transition to backup power can be carried out not only during a complete power outage, but also during power surges. In old, worn-out networks, this happens very often, and the UPS constantly changes the source in order to maintain heating in the house and prevent the boiler from turning off. Simply put, batteries are constantly under load and the faster they charge, the better. It is impossible for the uninterruptible power supply to allow the batteries to completely discharge. Please note that charging the battery requires additional power, which must be taken into account.

In a UPS with built-in batteries, as a rule, everything is already calculated, but if you increase the capacity using third-party batteries, be sure to calculate how long it will take for them to be fully charged and, based on this, select the power of the device.

Top 3. EAST EA901PS

Rating (2021): 4.69

Powerful uninterruptible power supply with two own batteries and the ability to connect additional modules. The energy of the UPS's own batteries is enough to provide the donor with electricity for 15 minutes. The transition to autonomy takes 3 milliseconds, while the sine wave practically does not change its shape, which has a beneficial effect on sensitive boards of boilers and other electronics. For convenience, the UPS is equipped with its own liquid crystal display and has the ability to configure some parameters. In particular, you can manually set the aspects at which it is necessary to switch to batteries.

Top 4. CROWN MICRO CMU-1000X

Rating (2021): 4.66

Compact UPS equipped with a lot of protective functions. An interactive type system is used here, but due to the rapid transition to autonomous sources, the donor practically does not notice the changes. During periods of inactivity, the device consumes virtually no electricity and is considered one of the most economical. It has its own stabilizer on board, protecting the network from sudden changes. It can level out the current when it drops to 110 watts and when it rises to 280 watts. This range means that the transition to offline mode will only occur in truly extreme situations, and not at the slightest surge, as is often the case with other UPSs.

Rating (2021): 4.71

Despite its compact dimensions and simple form factor, the One Station 600 UPS is capable of providing the boiler with energy within 15 minutes with an immediate transition to an autonomous source. It uses a redundant type system, but the transition speed is only 3 milliseconds, so the donor device board is not negatively affected by a sudden change in the sine wave. Unfortunately, the battery capacity is quite small, and it is impossible to expand the device’s capacity with additional batteries. There are three outlets at once, each of which has its own grounding.

Let's draw the line

I will name the best models, in my opinion, from those presented in the review for each price category.

If the question arises, which budget model to choose, then the best option would be Powerman Online 1000 BA . Double conversion of electricity, high accuracy of compliance with specified parameters, stylish design and reasonable price are the key advantages that encourage the purchase of this particular device.

It so happened that all devices in the middle price range were at the upper limit at a given cost. Therefore, the choice will be made based on the technical parameters of the UPS, reliability, and ease of use. The Energia PN-750 model best meets these criteria . This is an easy-to-use uninterruptible power supply, has an optimal set of functions and is very reliable. And you don't need to buy additional batteries.

Top 5. Ippon Innova G2 3000

Rating (2021): 4.58

The use of a dual converter means that even with a stable load on the network, the UPS still powers the donor from the battery. That is, the sinusoid is always stable and does not change during sudden transitions. All due to the fact that these transitions do not exist in principle. The device just stops charging. Personal batteries will last about half an hour. This is not much, but the capacity can be expanded. The housing has several corresponding connectors that allow you to connect auxiliary modules both in parallel and in series. A separate advantage will be simple controls and a display that displays maximum useful information.
