Review of gas boilers Siberia

Having a dependable heating system is crucial for keeping your house warm and comfortable during the cold months. A gas boiler is a common choice among homeowners due to its efficaciousness and efficiency in generating warmth. We’ll look more closely at the Siberia range of gas boilers in this review, analyzing their features, effectiveness, and suitability for insulation and heating applications.

The Siberia gas boilers are well-known for their sturdy construction and consistent heating efficiency in a range of weather conditions. These boilers are built with efficiency in mind, maximizing heat output while consuming the least amount of energy possible. This helps homeowners save money on their heating bills while maintaining year-round comfort.

The heating capacity and efficiency of a gas boiler are important considerations. Siberia boilers come in various sizes to accommodate various home sizes and heating needs. Whether you live in a big family house or a tiny apartment, there’s probably a Siberia boiler model that will fit your needs without breaking the bank.

Siberia gas boilers are designed with insulating features in addition to their heating capabilities to help reduce heat loss and increase energy efficiency. Maintaining a constant interior temperature and reducing the strain on your heating system are two major benefits of proper insulation, which also happens to result in lower energy costs and a cozier living space.

About the manufacturer

The trademark "Siberia" is overseen by Rostov-on-Don’sJSC"Rostovgazoappart." Most likely the biggest domestic manufacturer, Rostov-on-Don, also produces a relatively new line of RGA boilers, which are widely recognized to all AOGVs. Although the company was only incorporated in 2002, the production plant for boilers dates back more than a century, having released the renowned AOGV-80 in 1959. All of this indicates that the company has a great deal of experience producing gas-saving equipment, and there is a steady market for the models.

Boilers sold under the "Siberia" brand have proven to be dependable and trouble-free in real life. They are specifically designed to accommodate the unstable gas pressure in homes rather than using the purest coolant. Homes frequently contain even low-cost versions of heat exchangers made of steel that are prone to corrosion and have a lifespan of more than ten years.

90% efficiency is the highest for a simple design across all models. Additionally, it uses very little gas, though not nearly as much as the more costly Lemax models. For instance, the most well-liked Siberia 11 (11.6 kW) model’s maximum gas consumption is 1.18 m 3 /hour, while the 17.4 kW model’s is 1.76 m 3 /hour.

Although steel heat exchangers are prone to corrosion, the manufacturer’s heat exchangers are renowned for their longevity; installation practices and owner feedback indicate that they frequently last 10, 12, or even longer. The heat exchanger’s steel thickness is 4 mm, compared to the industry standard of 3 mm for low-cost boilers from other manufacturers. The majority of residential boilers have the well-known Italian EuroSit floor model automation, which is non-volatile. Polidoro is a standard and burner. With a device like that, the boiler is implied to have nothing to break and to have a service life limited only by the heat exchanger’s resource when operating competently.

Naturally, there are also well-known drawbacks that apply to practically all of the manufacturer’s models. First and foremost, owners emphasize the necessity of ongoing cleaning. It is preferable to clean the heat exchanger, burner, and igniter once a year (it takes approximately an hour), and some owners clean the boiler one or two times a year using a vacuum and a soft cloth (generally, it is desirable to maintain cleanliness in the boiler room). An obstruction in the boiler modules could cause issues with ignition and automatics.

Additionally, owners frequently complain that the boiler needs to be kept in a separate room because the burner igniter is noisy and the clicks or pops during ignition are too loud.

Otherwise, considering their price, all models are flawless, even when compared to other top domestic alternatives (otherwise it would be strange, given the century of experience of production). For over a decade, nearly all models have been operating trouble-free and without major service complaints.

Reviews of owners about gas boilers Siberia: advantages and disadvantages

The best and most famous models: characteristics and prices

Classic floor standing boilers Siberia

The most common, affordable, and traditional boilers with a steel heat exchanger. characterized by its affordable price, dependability, small size, and 4 mm thick heat exchanger steel. With an efficiency of 90%, the 11.6 kW model uses just 1.18 m 3 of gas per hour. available in versions of 11, 17, 23, 29, and 35 kW. Two-circuit models are also available; they have the prefix "K" (Siberia 11K, for instance) and are only 5–15% more expensive than single-circuit models.

Other than that, after more than 12 years of use, there have been almost no significant service complaints, and this model is regarded as the most dependable and successful among domestic gas boilers. It is present in practically every drawback previously mentioned, such as noisy ignition and sensitivity to clogging. It is not advised to use the model in closed type systems, where the working pressure is typically 1.5–2 bar, as the maximum allowable working pressure is only 1 bar.

KCHGO series

Among the best gas boilers from Siberia for heating a private home. With a sturdy cast iron heat exchanger, this model is bigger and heavier. Since cast iron hardly ever corrodes, these heat exchangers last for thirty years or longer, despite being much more expensive. In contrast to the previous model, the boiler’s permitted working pressure has been raised to 3 bar, meaning that it can now be utilized in any type of residential closed heating system that requires forced coolant circulation. Versions 16, 25, 40, and 50 kW are available.

Because the boiler’s burner and automatics—the renowned Italian EuroSit and Polidoro—remain the same, the 16 kW model’s gas consumption of 1.7 m 3 per hour has not changed. Everything else is the same as it was with the traditional steel floor standing units. One major drawback is that there are no two-circuit versions available. Even though cast-iron models are expensive, their costs are significantly lower than those of their foreign counterparts and among the lowest of domestic models.

Top Line series

The hinged model, whose housing already houses every heating system module required (circulation pump, safety group, expansion tank, etc.). It stands out for having a smoothly modulating burner, as evidenced by the highest gas consumption of 2.65 m 3 /hour at a 24 kW capacity. Copper heat exchangers are more heat-conductive and corrosion-resistant than steel ones. However, in two-circuit models, it is bithermal (twin), meaning that practically no washing and scale accumulation occurs. As such, coolant must be used as soft, purified water and should be changed as infrequently as feasible.

Among other things, there’s the ability to connect an external thermostat and protection against freezing and overheating. Although the model is relatively new and has only been in use for a few years, no significant service complaints have been made thus far. One major drawback is that it’s still hard to find in the assortment of online stores, making it difficult to buy. This is primarily because there are only two versions available: Top Line 24 kW (single-circuit) and Top Line 24C (double-circuit). No other versions are offered.

Price range: 21,500–26,00 rubles.

Whether you want to install a new boiler or replace your old one, our review offers helpful advice to help you choose the best Siberia gas boiler for your house.

Official site: where to see all models and operating instructions

The manufacturer’s official website in Russia is located at http://www.rndgaz.ru/.

All of the models that are currently available are listed in the "Siberia" section, along with a description; boiler passports are the only sources of detailed technical information. Full-fledged operation manuals are available in electronic copy under the "Infocenter" section. Each model’s manual includes detailed installation instructions, an algorithm for turning on and controlling operation, maintenance peculiarities, and schematic pictures.

Which boiler model is ultimately the best to choose

The decision is fairly straightforward: if money is tight, the traditional floor-standing boilers with steel heat exchangers are the best option (the most popular models are Siberia 11, 17, and 23K). If finances permit, it is preferable to go with a floor-standing boiler with a cast iron heat exchanger (series KCHGO); these units essentially have the same features, but the former is stronger and more dependable (because of its resistance to corrosion) and can be installed in a closed type CO.

Hinged Top Line: We advise selecting this option only in cases where space is extremely limited or when you wish to set up control via a programmable thermostat, which, under the right circumstances, can save you a significant amount of gas consumption.

Selecting the necessary boiler output is the most important step. The minimal amount of heating equipment power needed for an average Moscow climate zone home with two bricks of masonry and a 2.7-meter ceiling height is determined using the following straightforward rule: one kilowatt for every ten square meters of area. Additionally, we advise that a 15-20% reserve be made.

For instance, the minimum output needed for the 130 m³ house mentioned above is 130/10 * 1.2 (20% reserve) = 15.6 kW. In other words, a version with a 16 or 17.4 kW heat output is required.

We suggest increasing the obtained value by an additional 5–10% reserve if you decide to use the two-circuit version. In over 90% of cases, this calculation method is accurate. The result can be lowered by 5–30% if the house is well-insulated (using 10 cm or more of foam, for example) or if it is situated in a warm, southern region of the nation.

How to compute the necessary boiler output precisely Formula, correction factors, and individual calculations

How to switch on: a brief instruction

Since the well-known EuroSit 630 automation is installed in all floor standing models, turning on the boiler only requires following this straightforward algorithm:

1. Make sure that the gas supply tap is open and there is a draught in the combustion chamber (put a match to the window at the bottom of the boiler).
2. Turn the mechanical thermostat (rotator) to the "Off-0" position and then all the way to the "⭐" position.
3. Press and hold the solenoid valve button (start button in the center of the thermostat) for 30 seconds, then press the piezo ignition button near the thermostat once without releasing the start button. At this point the ignition burner should light up, if this does not happen, repeat the actions. If the wick burns steadily, continue to hold the start button for 60 seconds, after which it can be released.
4. Turn the thermostat to set the desired value of the temperature mode.

Please be aware that you can restart the boiler 60 seconds after the valve automatically closes following an emergency fade-out (such as wind blowing). This is a safety-related design element of the EuroSit 630. Many owners complain that it is extremely difficult to light the boiler after it has been extinguished, not realizing this.

Known malfunctions of Siberia boilers

As previously mentioned, the typical straightforward design of floor standing boilers does not indicate significant malfunctions, particularly if routine maintenance is performed on the basic modules. As a result, there is hardly any need for Siberian boiler spare parts. The igniter or thermocouple is only infrequently replaced; in most cases, this is due to oxidized contacts that are easily cleaned with an emery cloth.

Operational issues are more common than complaints about services. Owners encounter these kinds of phenomena most frequently:

Make sure the boiler is started using the previously mentioned algorithm. A reverse draught or no draught at all is the most common cause if you follow the instructions precisely. To check the draught, place a lit match against the burner module unit window at the bottom of the boiler.If the flame moves toward the boiler’s combustion chamber, the draught is fine; if it stays the same or disappears, either due to insufficient draught or wind-blown debris blowing through the boiler.

What to do in the event of a strong wind-related gas boiler blowout

Clogged ignition or main burners are another frequent cause. The burner module must be taken out of the boiler in order to disassemble it and clean the igniter and burner separately. Take care not to permit any scuffs or dents of any size.

If the pilot burner ignites but extinguishes after five, ten, or fifteen seconds, a back draft is most likely the cause of the issue. Use a lit match to check for back draft, just like in the case before.

Most often, an improperly designed chimney—that is, one that is too long, too short, or without a protective deflector—is the source of back draft.

A clogged gas valve (on the gas supply line) is the most frequent cause. Before the boiler activates, undo the gas pipe nut and gently blow out the tube and grid within.

Verify that the boiler is not running at maximum capacity and that it has sufficient heat output to offset the heat loss in the house if the temperature does not return to normal. To determine whether your boiler is truly underpowered, measure the amount of gas consumed during an hour of operation at maximum output and compare it to the factory values. If the consumption is equal to or greater than the factory value.

The error code E01 denotes the absence of flame. This may occur from a closed gas supply tap, a drop in gas main pressure, or a brief power outage (even for just one second).

A drop in system pressure below the critical mark (0.7 bar) is indicated by error E04. Air gaps, leaks, malfunctioning expansion tanks, or discharge valves are the most common causes. We have already covered every potential reason for a pressure drop in one of our earlier articles.

Siberia or Lemax: what is better

Similar in design but marginally more complicated are floor gas boilers, which also share similar burners and automation. Nearly all of the Lemax model range has 90% efficiency, although on average, 10% more gas is used. The maximum gas flow rate of the Lemax Premium-16 kW, for instance, is 1.9 m 3 / hr. Lemax boilers have a lower noise level, and their steel models can withstand up to 3 bar of pressure in the circuit. But they cost ten to twenty percent more.

Siberia is more affordable, simpler, more dependable, and more economical. but lacks the benefits listed above that come with the Lemax model line. Both manufacturers are deserving of notice in general, and it’s not for nothing that they lead the domestic gas boiler market in sales.

Lemax gas boiler overview The most well-known and prevalent domestic model

It’s clear from examining the features and functionality of Siberia gas boilers that they provide a number of advantages for both heating and insulating homes. These boilers come in models that are appropriate for different household sizes and heating needs, and they are made to offer effective heating solutions.

The dependability of Siberian gas boilers is one of their best qualities.

This enables them to contribute to sustainable heating solutions while also being economical for homeowners and environmentally friendly.

Siberian gas boilers are also renowned for their simple installation and user-friendly design. Homeowners don’t need to be highly technical to operate and maintain their boilers thanks to simple controls and instructions. Siberia boilers are more appealing overall for both residential and commercial applications because of their accessibility.

To sum up, Siberian gas boilers present a strong option for meeting residential heating and insulation requirements. Their blend of dependability, energy efficiency, and intuitive design makes them a compelling choice for homeowners wishing to modernize their heating systems.
