A modern gas boiler, in addition to the main fuel, also needs electricity. Several modules are powered from it at once: a control board, a circulation pump, an ignition module, ventilation and a GMS unit for remote control. For all this to work even during power outages, autonomous sources are required, but a sharp transition to them negatively affects the operation of the device. In particular, when the sinusoid changes, the electronic board often burns, which is almost the most expensive unit in the entire system. To prevent this from happening, it is necessary to install an uninterruptible power supply, which not only transfers the system to an independent mode, but also protects it. And our article will tell you how to choose this device and what nuances to pay attention to.

Principle of operation
Which type of UPS is best for a gas heater?
There are three types of uninterruptible power supply: continuous, interactive and standby. Offline and Online markings are also often found, which to some extent explains the difference between them.
The UPS is an intermediary between the network and the built-in battery. It does not change the input voltage and most often does not control it at all. The device turns on only when the current goes beyond the set range, for example, when it falls below the set mark or when it completely disappears. This is the most budget option that does not produce noise and does not take up much space. But if the issue of saving is not in the first place, it is better to refuse it. Such a device is capable of providing energy only for a few minutes and does not have the ability to manually adjust the current and other characteristics.
the source is the next step in the development of the UPS. It analyzes the incoming voltage and reacts to the slightest fluctuations in the network. UPSs work as stabilizers, and when switching to an autonomous source, they do it very quickly and without changing the sinusoid. This principle of operation significantly increases the service life of the gas boiler board, which does not like vibrations. The interactive uninterruptible power supply normalizes all parameters and brings them to the optimal value.
UPS is considered the best for gas heaters. With them, power always comes from batteries, which the UPS constantly charges when there is current in the network. This allows you not to waste resources on adjusting the sinusoid during the transition and reduces the time for switching between modes to zero. Of the shortcomings, increased noise and the highest possible price tag stand out here.
TOP 10 best UPS for gas boilers
Under the UPS for a gas boiler, as a rule, they raise a line-interactive uninterruptible power supply with an external or built-in battery. This is an inverter combination with an additional battery supply, which ensures continuous operation and voltage stabilization, even if it “jumps” or is temporarily turned off.
Many gas boilers are volatile — they need a round-the-clock connection to the network. In the absence of electricity, the equipment cannot function, respectively, the heating system cools down, and in winter it can completely freeze and burst. UPS of various types — interactive, with double conversion, are designed to ensure the uninterrupted operation of household systems and prevent emergencies caused by overloads and short circuits.

How to correctly calculate the power of the 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 not true. Starting currents are much higher than linear ones. For example, if you have a pump with a nominal value 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 life of the boiler’s electronic modules. Some experts advise taking devices whose power is three times the nominal requirements of the boiler, but this is already too much. Doubling the digits is 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.
CROWN MICRO CMU-1000X
The best standby UPS with high build quality

15 Best Uninterruptible Power Supplies (UPS)
How long will the UPS run offline?
If your home has autonomous power, and the UPS is used only to switch the network to it, you can safely skip this tip. It applies only to those devices that are equipped with their own batteries, from which your gas boiler will work during power outages.
It is easy to guess that the higher the battery capacity, the longer the heating will be in the house, and this is an indisputable fact. In the description of each unit there is an indication of how long it will work at full load. In the cheapest models, this is a few minutes. In more expensive ones — up to a couple of hours. It’s not worth waiting for more. There are also models with the possibility of expanding the capacity. They just need to buy a battery and connect it to the device, thereby increasing autonomy.
How to choose a UPS for a heating boiler
The main parameters that you should pay attention to when choosing a UPS for a gas boiler:
- Device type. Interactive models are sensitive to input voltage and switch to battery mode at the slightest drop. They are worth taking if the installation of a generator is not planned in the future. In all other cases, experts recommend purchasing models with a dual converter.
- output power. It should be enough to service equipment, while the minimum indicator is usually multiplied by a factor of 1.2 to create a small margin of 10–20%.
- Battery capacity – it determines the battery life in the event of a complete power outage.
When choosing one model from two similar ones, it is better to purchase a device with the ability to install additional batteries.
It is also worth paying attention to the brand. It is better to purchase equipment from trusted companies that fully service their equipment during the warranty period and after it.
How quickly will the UPS change mode?
If you decided from the very beginning to choose a continuous UPS, you do not need this advice. The fact is that backup and interactive sources are powered from the network, and at the time of a power outage they switch to batteries. It takes time, and the less time, the better. The valid range is 3 to 10 milliseconds. True, this parameter greatly affects the price of the device. But it should be understood that even the smallest gap in the current supply negatively affects sensitive electronics. That is why the best option is a continuous UPS, which always runs on batteries that are constantly being charged. It does not have a switch at all, it just stops charging the battery at the moment of a power outage.
Continuous UPS with capacity expansion
Uninterruptible power supply with two batteries on board and special expansion slots. If the initial battery capacity is not enough for you due to long power outages, you just need to buy a couple more batteries and double the source’s autonomy.Rating member:
15 Best Uninterruptible Power Supplies (UPS)
Experts classify uninterruptible current supply devices for heating systems into several categories depending on the principle of operation, type of installation and the availability of additional options.
But since the main nuance in choosing a device is precisely the technical characteristics, the following types of UPS are most often distinguished:
- regular or reserve. They are also called offline devices. Such devices provide backup power and become necessary in the event of a power outage. The advantages of such devices include low price, compactness, the ability to install on a wall or put on the floor. But the disadvantages include limited functionality, in particular, backup models do not stabilize the voltage of the electric current.
- with stabilizer. AVR stabilizer device is characterized by the presence of a voltage rectifier, however, it is basic, the simplest. The battery capacity is small, the reserve of the device is only enough for 20 minutes of operation of the boiler when the power is turned off. But it is possible to connect an additional battery (external), in which case the power will increase, and the device will provide up to 10 hours of operation without power supply.
- Online systems. This is a modern solution in the issue of voltage stabilization and are considered the most reliable models. A double converter, consisting of an inverter, batteries and a power supply, converts AC to DC, and then back to AC, but during processing, the device makes the current stable. When the power is turned off, the uninterruptible power supply system runs on batteries and continues to ensure efficient operation of the heating unit for a long time.
What type of sinusoid is the most optimal for a gas boiler?
The output signal is in the form of a sinusoid, and the smoother it is, the better for the powered device. A sinusoid deviated from the norm by 8% or more is called approximate, that is, incorrect.
An approximate sinusoid may also be referred to as modified or quasi. If any of these names are in the description of the UPS, then it uses the “wrong” signal, which may adversely affect the operation of the boiler.
Bringing the sinusoid to normal requires the complication of the UPS and, as a result, its rise in price. Note that continuous or online sources are devoid of such a problem, which once again speaks of the rationality of their use. But even among interactive and backup devices, there are models with a smooth signal. A strong change in the sinusoid can lead to the inability to start the system or even to the failure of some particularly sensitive modules.

15 Best Uninterruptible Power Supplies (UPS)
Which uninterruptible power supply is better to buy
In addition to choosing a model according to technical parameters and a manufacturer, it is important to get to know the additional functionality better. Modern UPSs have become so “advanced” that, in addition to the main options, they include many secondary and rather useful ones. Often, it is this factor that helps determine which uninterruptible power supply is better to purchase in a particular case.
In our ranking of the best UPS for gas boilers, according to customer reviews, there are two types of sources: interactive and dual converter. There is a third type — backup, these are simpler devices that supply energy from the battery to the consumer. They are also suitable for household heating equipment, however, they are not so popular and not very common due to their simple design and average capabilities.
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 with a complete power outage, but also with its jumps. In old, worn-out networks, this happens very often, and the UPS constantly changes the source in order to keep the 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 that the uninterruptible power supply allows the batteries to be completely discharged. 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 with 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.
The need to purchase
Modern gas boilers need a constant connection to a power source. The control unit, circulation pump, ignition system and forced ventilation operate from the network.
Advanced users install special modules with which they control the system from a distance.
When the power goes out, the device continues to work. Most models are capable of not only providing the boiler with power, but also adjusting its operation during power surges.
Benefits of an uninterruptible power supply:
- acceptable cost;
- simple installation that does not require special knowledge;
- excellent work with voltage drops;
- automatic control of all parameters;
- service life up to 7 years;
- silent operation.
What other protection options does the device have?
The best uninterruptible power supply is the one that protects not only the gas boiler, but also itself. There can be many problems in the network:
- short circuit;
- network interference;
- high voltage impulses;
- voltage drop.
Any of these problems can harm your UPS, and the more protection it has, the better. Ideally, choose a device with the maximum set of additional protective functions, but it will be expensive. The most extensive list is found in continuous devices. With them, your boiler is constantly powered by batteries, no matter what happens on the network. Troubleshooting is done directly at the UPS without reaching the powered device.
Existing UPS for boilers are usually divided into 3 groups:
- Offline UPS. The simplest and cheapest devices. The design of uninterruptible power supplies consists of a battery, a voltage controller and an inverter that converts direct current to alternating current. At the output, devices of this type give out a voltage of 170–270 volts. Off-line UPSs do not have voltage stabilizers. The main disadvantages of the devices are rapid wear with frequent voltage drops and incorrect operation when current is supplied to the device from gasoline or diesel generators.
- line-interactive. Line-interactive devices are referred to the middle segment in terms of operational characteristics. The design is equipped with a stabilizer that equalizes the output voltage of the network up to 220 volts. The disadvantage is incorrect operation when electricity is supplied from generators.
- Online. The devices work stably when connected to current generators. They have a complex structure. This is the main reason for their high cost. These are the most reliable, correctly working devices, with a long service life.
How many outlets and connectors does the device have and what type are they?
If the heating in your home is provided by a multifunctional, double-circuit boiler, you will need only one outlet. But when designing complex systems consisting of several modules, you will have to connect many devices to the network at once. For example, often the pump is placed separately, and, accordingly, it requires an independent connection. Before choosing a UPS, clearly define which units will be connected to it. Of course, you can always use extension cords, adapters and tees, but this is inconvenient, and extending the wire is not the best option for highly sensitive electronics.
Also, some UPSs have connectors for connecting third-party batteries. Be sure to pay attention to them. If you ever decide to increase the capacity of the source, you will need additional inputs, and they can be designed for just one expandable module.
ELTENA (INELT) One Station 600

15 Best Uninterruptible Power Supplies (UPS)
UPS or generator — which is better?
Not only UPS, but also generators are used as a backup power source. To decide which one to prefer, it is necessary to study the advantages and disadvantages of each of them.
The advantages of UPS are:
- ease of operation;
- lack of strict maintenance requirements;
- high degree of security;
- no need for fuel;
- no harmful fumes.
- strict requirements for indoor humidity;
- higher cost than generators;
- low power;
- the ability to work only at a temperature of 10 ° C;
- the need to change the battery every 2–3 years;
- It takes several hours to fully charge.
Generator benefits include:
- fast startup;
- low price;
- quite a long time of work;
- the ability to work at sub-zero temperatures.
- special requirements for installation and operation;
- fuel requirement;
- release of harmful substances;
- noise during operation.
Both power supplies do an excellent job of their functions, so you can decide which one to choose based on financial capabilities and personal preferences..
What are the additional features that simplify or improve the operation of the UPS?
The more expensive the UPS, the more additional features it has. But in some cases, this is exactly the moment where you can save a little by refusing unnecessary additions. For example, if your gas boiler is located in a separate room, you will not need the sound alarm function for malfunctions. As well as a liquid crystal display with information, for which some manufacturers pretty much wind up the price tag.
Also often found is the cold start function, positioned as very necessary and useful. It allows you to start the equipment in the absence of voltage in the network. But if you have an interactive or backup UPS with small batteries, it makes no sense at all. You still won’t be able to start the heating. But the most expensive feature is the GSM module that links your UPS and smartphone. There is already a matter of personal convenience and necessity.
Which manufacturers should be preferred?
In the question of which UPS to choose, not the last place is occupied by the brand, that is, the manufacturer of the device. The company’s products are most in demand among buyers Bastion

not the best choice. As practice shows, its UPS does not have sufficient reliability to work with the sensitive electronics of a gas boiler.
I. UPS with one external battery (12V)
Models with connection of one external battery, we recommend using with small heating boilers with a maximum load of up to 300–400W for short or medium battery life. There are 2 significant models on the market:
1 place. Eltena (Inelt) Monolith E 1000LT-12v ~21 450r.
Eltena with 12A charge current and one 100Ah battery
A new model in the Monolith line from Inelt. A product of the Chinese factory Kehua Tech (www.kehua.com), adapted to the Russian market.
Advantages of UPS:
- A good range of input voltages is 110–300V without switching to a battery.
- Charging current 12A, which is relevant when connecting a battery with a capacity of up to 250Ah.
The disadvantages include:
- High price for the device
- New 12V model for the manufacturer
2nd place. Helior Sigma 1 KSL-12V (no longer available in Russia)
This uninterruptible power supply, adapted by our engineers to Russian conditions, manufactured by Helior Corporation (www.heliortec.com) has been consistently ranked first in sales reports for more than a year. Reasons for popularity in addition to affordable price:
- The lowest fan noise level among analogues (rotation speed depends on the load)
- There is a special mode of operation from the generator (the permissible range of the input frequency is expanded)
- Compact dimensions and the ability to operate in two positions
- Sufficiently high reliability when working with heating systems
- A relatively narrow range of acceptable input voltage values that the source can “pull out” without switching to the battery.
- Average charge current, which allows you to connect batteries with a capacity of 30 to 150Ah.
Top 5. Ippon Innova G2 3000
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 sharp transitions. All due to the fact that these transitions do not exist in principle. The device just stops charging. Personal batteries will last for about half an hour of work. This is not much, but the capacity can be expanded. There are several appropriate connectors in the chassis, allowing you to connect auxiliary modules both in parallel and in series. A separate plus will be simple operation and a display that displays maximum useful information.

Top 4. CROWN MICRO CMU-1000X
Compact UPS, equipped with a mass of protective functions. An interactive type system is used here, but due to the rapid transition to offline sources, the donor hardly notices any changes. During the period of inactivity, the device practically does not consume electricity, and is considered one of the most economical. On board there is its own stabilizer that protects the network from sudden drops. It can equalize the current when it drops to 110 watts and when it rises to 280. This range means that the transition to offline mode will only occur in really extreme situations, and not at the slightest jump, as is often the case with other UPSs.

Do I need a stabilizer if there is a UPS
Typical equipment of a modern boiler is complex microprocessor electronics.
It performs several useful functions:
- maintenance of operating modes;
- operational check of control parameters;
- user notification;
- automatic diagnostics.
The performance of these units is significantly affected by the power supply parameters:
- amplitude and shape of the signal;
- impulse interference.
A specialized stabilizer for the UPS boiler can be selected taking into account the real state of the network. The standard power supply is not able to eliminate the noted shortcomings.
