About the manufacturer
LLC "Signal-Teplotekhnika," which has over 17 years of experience producing heating equipment, is in charge of managing the trade mark "Signal." Additionally, the company is present in the markets of Belarus and Kazakhstan through dealer networks. It has made a name for itself in the Russian market by producing some of the cheapest single- and double-circuit classic budget gas floor standing boilers. Homes no longer contain the original boilers, though you can still find examples that are 12–14 years old.
Overall, these are great and dependable models for use in homes; they are efficient and use an average amount of gas, and the Italian automatics and burners work flawlessly. It’s crucial to understand, though, that you shouldn’t anticipate any durability from even the most basic construction. The manufacturer, like many others in this price range, uses standard 3 mm thin steel heat exchangers, which are not bad.
Steel is susceptible to corrosion even with high-quality anti-corrosion coatings; after ten to fifteen years, it rusts and deteriorates completely, which causes heat exchangers to leak. The service life is typically dependent on the operating conditions: if you use soft, clean water as a heat carrier and change it as infrequently as possible, the service life can reach 14 to 15 years; if not, leaks are frequently discovered after 8 years of use.
Other drawbacks include inadequate assembly quality, customer complaints about potential automation issues during use, the fact that boilers are inexpensive and simple devices without many features, and a lack of protective systems. Installers observe how difficult the connection and installation are in comparison.
It is also important to note that the gas input pipe has a non-standard diameter of 1/2′′ rather than the standard 3/4′′. This means that replacing the old boiler with a new one will probably cost an additional 500–1,000 rubles. additional for connecting and installing.
Nonetheless, practically every one of the aforementioned drawbacks applies to all low-cost boilers made in Belarus, Ukraine, or Russia.

The best and most famous models: characteristics and prices
S-Term" series
They are all represented by models with capacities ranging from 7 to 25 kW, and their efficiency is 90%. For the purpose of heating and hot water supply, there are two types of boilers called "Signal" (KOV SKVs) and single-circuit (KOV SKS). The copper used to make the secondary DHW coil. Actually, this is a range of the most affordable, standard models. The 10 kW version’s maximum gas consumption is 1.2 m 3 /hour, which is decent but not a record; the 16 kW version’s maximum gas consumption is 1.8 m 3 /hour.
Based on installation experience and owner feedback, when the boiler is set up correctly at the beginning, over 95% of the time it will operate trouble-free for ten years. The wick and nozzle contacts burning out is a known issue in addition to the drawbacks already mentioned. The low 1.5 bar permissible operating pressure threshold is another major drawback. This indicates that the boiler should not be used in closed heating systems with forced coolant circulation, where the working pressure is typically between 1.5 and 2 bar.

Comfort" series
"Signal" is among the best boilers for heating a private home. The models in the series range in capacity from 10 to 50 kW, and they are all floor standing. Both single- and double-circuit versions are available. Actually, the only thing that separates it from the previous series is the heat exchanger’s design; at 3 bar, the boiler can now be used trouble-free in practically any closed-type home heating system.
Though the heat exchanger’s strength has increased gas consumption as well, the 16 kW model’s maximum flow rate is now 1.9 m 3 /hour as opposed to the S-Term’sprevious1.8 m 3 /hour. Even though the "Comfort" series’ prices are higher, they are still significantly less than the going rate in the market.
25 000–29 500 rubles is the cost.

Making the right choice for your gas boiler is essential when it comes to insulation and home heating. To assist homeowners in making an informed choice, we examine the "Signal" gas boilers in more detail in this review. We’ll look at the main characteristics that set these boilers apart, from performance and efficiency to dependability and ease of use. To create a cozy and energy-efficient home, it’s important to weigh the benefits and drawbacks of "Signal" gas boilers, whether you’re thinking about building a new home or looking to upgrade your existing heating system.
Which boiler model is better to choose in the end
The suggestions are very basic. If your budget is tight and your system is open to natural coolant circulation, the S-Term series models are a great option. A more costly model from the "Comfort" series with a higher permitted working pressure should be selected if the boiler is to be used in a closed heating system.
Larger capacity boilers are uncommonly installed in private residences; therefore, selecting models with higher capacity is only required in the event that the S-Term and "Comfort" series have no equivalents with the same heat output.
The most widely used model is the 10 kW single-circuit Signal Comfort KOV-10 ST heating water boiler. To avoid overspending and to ensure that the house has the necessary heat output even during the coldest decade, it is crucial to select the boiler output based on its specific needs. The minimal power needed for a typical uninsulated home in the Moscow region with two bricks of masonry and a ceiling height is determined using the following rule: one kilowatt-hour for every ten square meters. Additionally, we advise setting aside 10–15% of the reserve.
For instance, the minimum required heat output of the heating equipment for the 120 m 2 house mentioned above is 120/10 * 1,2 (20% reserve) = 14,4 = 15 kW. Since there aren’t any boilers in the model range with that capacity, we round up to the next higher value, which is up to 16 kW.
It is advised to lay an additional 5–15% reserve when selecting a two-circuit version. Specifically, the two-circuit model in the example will have a final power of 16.56 kW, or 14.4 * 1.15 (15% reserve).
How to compute the necessary boiler output precisely Formula, correction factors, and individual calculations
How to light the boiler
The algorithm varies somewhat based on the automatics. Nonetheless, models up to 20 kW are typically chosen because they are always equipped with EuroSit 630; using this model as an example, let’s look at how to light the boiler:
- Open the gas supply tap on the gas supply line, turn the mechanical rotator counterclockwise as far as it will go (up to the value "⭐").
- Press and hold for 60 seconds the start button in the center of the regulator, then, without releasing the start button press the piezo ignition button next to the regulator. The start button should continue to be held for another 30 seconds. If the igniter (wick) is lit – excellent, otherwise, to turn on the boiler, you need to repeat the procedure.
- Turn the regulator knob to the position corresponding to the desired temperature.
The instruction manual will always include a detailed description of the ignition algorithm. For every automation model, there are comprehensive instructions with accompanying photos on the official website.
How to clean its modules
We have previously released comprehensive guidelines for cleaning gas boilers. To avoid redundancy, we will enumerate solely the components that require cleaning when dealing with "Signal" gas boilers:
- Heat exchanger. To clean it, you need to remove the top or side panel of the housing, depending on the model. Cleaning is carried out with a metal brush, sandpaper and other convenient means.
- Main burner. It is removed without disassembling the boiler by unscrewing the screws at the bottom of the front panel. The main burners are rarely dirty, use a cloth for cleaning, in case of heavier soiling use metal brushes.
- Igniter, thermocouple and other automation contacts. The igniter is located above the burner, in the center (for exact location see the following table). in the instructions). Do it carefully, using zero-grit sandpaper or a soft brush, without scratching or deforming the parts.
Known malfunctions of boilers "Signal"
Breakdowns in the first 5-8 years of operation are rare because of the straightforward and tested design. The most common issues are solenoid valve and thermocouple malfunctions, which are typically resolved with basic cleaning (including oxidized contacts). The igniter may burn out occasionally, and in the most extreme circumstances, corrosion may cause the heat exchanger to leak.
Otherwise, during the course of operation for more than a decade, there have been almost no significant service complaints with proper operation, which includes the use of clean softened coolant, cleanliness in the boiler room, and an annual simple cleaning of the aforementioned modules (approximately one to 1.5 hours of work).
