UPS for gas heating boilers: how to choose, TOP 12 best models, maintenance tips

When installing a heating boiler with a pump and electronic control, it is recommended to immediately purchase an uninterruptible power supply (UPS).This device will allow you to continue to warm rooms even in the absence of electricity. But not every device is capable of ensuring equipment operation for a long time.

We'll tell you how to choose wisely UPS for gas boilers. The article we have proposed describes in detail the varieties used in practice, and also provides a rating of the best uninterruptible power supply models. Taking into account our recommendations, the selection and operation of the device, and the heating system as a whole, will not create the slightest problem.

The need for a UPS for heating boilers

Most modern gas boilers require a constant connection to a power source. Works from the network circulation pump, control unit, ignition system, forced ventilation.

Advanced heating equipment users install GMS modules, allowing you to control systems from a distance. When there is a power outage, the operation of the entire set of listed devices stops, and the heated room begins to cool.

Boiler fire due to short circuit
It is easier to install a UPS and prevent the electronic components of a gas boiler from catching fire due to overloads than to pay for the consequences of a large-scale fire

Electronic components gas boilers They are also picky about voltage parameters.The large length of electrical networks in country houses often leads to a decrease in power in the network, as well as to a deterioration in the frequency characteristics of the current. As a result, the boiler may work intermittently or not turn on at all.

All electrical problems are solved by installing a UPS, some models of which are capable of not only providing backup power to equipment, but also correcting voltage and frequency deficiencies.

Automatic voltage stabilization by uninterruptible power supply
Automatic voltage stabilization by an uninterruptible power supply allows you to reduce the load on the electrical converters of the gas boiler board and increase their service life

The advantages of installing an uninterruptible power supply for a gas boiler are:

  1. Protection against voltage surges. The cost of a UPS is several times lower than the price of a new electronic board for the boiler.
  2. Easy to install, no special skills required.
  3. Automatic control over the electrical parameters of the network.
  4. Service life up to 5-7 years.
  5. No need for servicing.
  6. Quiet operation.

In severe frosts, stopping heating equipment even for several hours can lead to rupture of pipes located close to the street. Therefore, ensuring continuous operation of the boiler using a UPS is not a whim, but a rational solution to save time and money.

Operating principle of uninterruptible power supply

The main task of a UPS is to supply sufficient power to the network when the lights are turned off. The switch to power supply from rechargeable batteries (AB) must occur in a fraction of a second so that the connected equipment does not have time to turn off.

Uninterruptible power supplies are also capable of stabilizing the voltage, rectifying the sinusoid and maintaining the current frequency within normal limits. But not all models have additional functions.

Operating principle of a UPS for a boiler
When choosing an uninterruptible power supply for your heating system, you can take a more powerful device so that you can additionally connect other devices to it if necessary.

The UPS design is not the same.

In maximum configuration uninterruptible power supply consists of the following elements:

  • frame;
  • accumulator battery;
  • current and voltage converters (inverters, rectifiers, etc.);
  • switch;
  • control chip.

The following characteristics of the UPS are important for the operation of the connected equipment:

  1. Type of output voltage curve: approximated or regular sinusoid. The first option is less preferable because it is unusual for most electronic devices and leads to increased wear and tear.
  2. Power consumption. Pump and fan motors have high starting currents, so the maximum performance of the UPS should be at least 2 times the electricity consumption of the boiler.
  3. Speed ​​of switching to a backup power source. The higher it is, the better for the connected equipment.
  4. Electrical capacity. The battery life of the entire heating system depends on it. To increase capacity, additional external batteries can be connected to the UPS.
  5. Life time. It depends on the operating mode and internal structure of the batteries.
  6. The range of input network parameters allows the uninterruptible power supply to produce acceptable voltage, frequency and sine wave without switching to the battery.
  7. Presence of grounding (“through” zero).

In offline mode, UPSs are capable of producing 2 types of sinusoids:

  • smooth;
  • approximated.

A smooth sine wave is more acceptable and always guarantees normal operation of the connected equipment.

UPS operating time table
The indicated operating times of the equipment from the uninterruptible power supply are approximate.The exact time can be found by testing a specific set of equipment

The cost of uninterruptible power supplies directly depends on the battery capacity, additional functionality, as well as compliance of the output current and voltage parameters with standard values. However, even the cheapest UPS is better than no UPS at all.

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.

Option #1: backup

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.

Backup low-power uninterruptible power supply
The control elements of inexpensive backup uninterruptible power supply units are usually limited to one button, various combinations of clicks 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:

  1. No noise.
  2. High efficiency when powered from the mains.
  3. Low price.

Disadvantages of off-line uninterruptible power supply:

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

Option #2: 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.

Line interactive UPS
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 input electrical wiring to the house. Usually they are connected to capacious external batteries.

The advantages of line-interactive UPS are as follows:

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

Disadvantages of linear-interactive uninterruptible power supplies:

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

Line-interactive UPSs are purchased more often than backup ones, because they are additionally equipped voltage stabilizerallowing heating equipment to operate more correctly.

Option #3: 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 UPS exploded view
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 may cause damage to the UPS, but not to the unit connected to it. geyser or a floor boiler.

Advantages of continuous uninterruptible power supply:

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

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

  1. Increased noise and heat generation during fan operation.
  2. Low efficiency (80-94%)
  3. 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.

Rules for choosing an uninterruptible power supply

The capriciousness of the electronics of gas boilers does not allow saving on the reliability and functionality of uninterruptible power supplies. Choosing a UPS for a heating boiler is quite complicated due to the variety of their technical parameters and the many equipment manufacturers.

But there are a number of characteristics of uninterruptible power supply systems that must be taken into account first:

  1. Duration of continuous operation in offline mode.
  2. Apparent and active power.
  3. The nature of the sinusoid at the output.
  4. Limits of operating voltage ranges.
  5. Possibility of connecting external batteries.

The duration of continuous operation of the UPS in offline mode directly depends on the battery capacity.If you are not sure that the built-in resources will be sufficient, then you can purchase a UPS with the ability to connect additional batteries.

IBS with external battery system
The capacity of the uninterruptible power supply system can always be increased by purchasing new batteries. It is advisable to choose identical batteries

The technical characteristics of uninterruptible power supplies indicate the values ​​of total and active power. It is desirable that the second parameter be twice the total linear power of the heating equipment. This will allow the UPS to withstand the starting currents of the pump and fan motors without negative consequences.

The values ​​of the operating voltage limit ranges are especially relevant for country houses. In the evening, on lines remote from the transformer, it can drop to 160-170 V. In this case, the UPS will constantly switch power to the battery, so it is better to purchase an uninterruptible power supply with a built-in stabilizer and a low operating voltage threshold.

Approximated and pure sine wave
Approximated (1) and pure (2) sinusoid. All electronic equipment of a gas boiler is designed to operate on a pure sine wave, so its approximated type may interfere with the operation of individual components

An approximated sine wave has a bad effect on the operation of electric motors: they hum and performance decreases.

The microcircuit of a gas boiler may also work unstably, which is why the equipment may turn on or off spontaneously. Therefore, to power heating systems, it is preferable to purchase a UPS with a smooth sine wave, which will not create problems.

Uninterruptible power supplies have many additional technical characteristics, but their values ​​are not so critical for the operation of a gas boiler.

Battery types

For UPS, only lead-acid batteries (LAB) are produced, which are heavier and larger than lithium ones, but much cheaper. Uninterruptible power supplies use sealed batteries that are safe and do not require maintenance.

Comparison of gel and fiberglass batteries
The sealing of lead-acid batteries can be deceptive, so don't push your luck and turn the devices on their side or upside down.

There are two types of UPS batteries on sale:

  • gel (GEL);
  • fiberglass (AMG).

Silicon compounds are added to the electrolyte of gel batteries, making it very thick. As a result, the battery contents do not spill out when shaking or spill out when the device is tipped over.

Oxygen and hydrogen released during operation are absorbed by the gel and slowly interact with each other to form water. This ensures complete battery safety.

Internal structure of gel battery
The gel battery does not have liquid inside in the usual sense. It consists of several independent flasks, inside of which there are synthetic electrodes coated with a viscous substance

The interior of AMG batteries is filled with porous fiberglass mats, which also help slow down the interaction of oxygen and hydrogen. The disadvantage of such batteries is the liquid electrolyte, which can still leak if the battery is damaged or if it is tipped upside down.

Fiberglass battery
If the fiberglass battery is mechanically damaged, it is strictly forbidden to collect the leaking liquid with a rag. It is a strong acid that can burn the skin

Due to greater safety, gel batteries are 10-20% more expensive than fiberglass batteries with similar capacity.But if the UPS for heating equipment stands quietly on the floor, then there is no point in paying extra money.

Many UPS systems provide the ability to connect external batteries. When using several batteries in parallel, it is important that they have the same technical characteristics. This will allow the batteries to be discharged and charged evenly and will increase the resource of each of them.

Tips for using the UPS

Installing a UPS is quite simple - just read the instructions and connect all external devices according to the diagram described in it.

IBS with active cooling
The efficiency of powerful uninterruptible power supplies is reduced due to the constant operation of the fan, which provides cooling to the current converters and batteries located inside.

The operation of uninterruptible systems is simple and does not require human intervention.

However, there are operating nuances not described in the instructions that you must familiarize yourself with:

  1. The UPS and external batteries should not be located close to each other or heat sources. The optimal temperature for operating this equipment is 20-25 °C.
  2. The room with uninterruptible power supplies should not be damp; the formation of water condensation in it is especially dangerous.
  3. It is undesirable to use line filters and tees at the UPS output.
  4. If the design of the uninterruptible power supply provides for grounding of the case, then it must be provided.
  5. The UPS must be permanently connected to the network after commissioning.

Following these simple rules will extend the life of the uninterruptible power supply and protect the house from fire and short circuit.

    My mistake was to install the boiler, but not install the UPS. In my small town, the power is constantly turned off and the house cools down instantly, especially in winter. It's kind of sad...
