Solid fuel boiler Siberia - review of KVO and Hephaestus models

Features of Siberia boilers

Siberia-Hephaestus boiler
The NMK plant has been operating since 1995 and is based in Novosibirsk. The heating boiler Siberia is presented in two versions: Hephaestus and KVO. All gas appliances in the series are standard classic units and have a simple design. It includes the boiler itself and the water jacket supplied with it. Due to the minimum number of parts and compact sizes, the devices can be located in any part of the house.

Upon closer examination, you should pay attention to the grate, cross beams and cover. All Siberian boilers are created using universal technology and consist of almost the same elements. The grille is designed to increase the area of ​​thermal volume and achieve maximum effect. The beams are placed in the path of flue gases to direct heat into the heating system. The lids are equipped with holes for coal and have a standard shape.

Heating boilers Siberia Hephaestus and KVO - review of models and reviews

The heroes of our review today are heating boilers produced under the Sibir brand. We will analyze in detail how they compare favorably with competitors and which ones have disadvantages. The owners, who agreed to leave their review especially for kotlydlyadoma.ru, will tell us about the intricacies of their work.

Novosibirsk produces solid fuel boilers “Siberia” of two series “Gefest” and “KVO”. Let's look at each of the models in turn and find out what advantages these devices have among their Russian counterparts.

Steel boilers for wood and coal "Sibir" KVO

The KVO series was specially designed for those who need an inexpensive domestic boiler for a country house or cottage. The manufacturer tried to take into account all the wishes of consumers and create a truly worthy and versatile heating device.

In total, 5 standard sizes of Siberia boilers are produced: KVO 10, 12, 15, 20, 25 kW. The main material for manufacturing is heat-resistant steel, but some parts are made of cast iron.

“Sibir” KVO series is a classic solid fuel boiler with a water jacket, but still its design has a number of features:

• To increase efficiency, a water-tube grate is used. The grate on which the fuel combustion process occurs consists of pipes connected to a water jacket. This further increases the heat removal area and thereby the efficiency of the boiler.
• In the combustion chamber, in the path of flue gases, there are transverse beams filled with coolant. As in the case of a grate, this allows you to maximize the heat from the burning fuel and direct it to the heating system.
• The boiler lid is a cooking surface made of 12 mm thick steel with holes of various diameters for installing cookware. In essence, the Siberia KVO boiler is a hybrid of a heating device and a stove. It is also convenient to pour coal through these round holes in the lid.
• In addition to heating the coolant using the energy of burning wood or coal, it is possible to install a 3 kW heating element. It can be used to maintain the required temperature in the heating system at night or to prevent the coolant from freezing during short-term departures from home.

For ease of installation and piping, each standard size has several options for the location of the flue gas pipe and the supply and return pipes. For example, the pipes can be located on the left or on the right wall.

The operating principle is no different from other traditional combustion devices, such as the KChM 5 cast iron boiler using solid fuel. Coal or firewood is loaded into the firebox and ignited. Solid fuel, when burned, heats the coolant in the heat exchanger. Through the supply line pipe, the coolant enters the heating system, giving off heat to the premises, and then returns back to the boiler.

Let's look at the main characteristics of the KVO series:

Especially for kotlydlyadoma.ru, we asked one of the owners of the Sibir KVO boiler to talk about the experience and nuances of its use, and here is his review:

I installed the Sibir KVO 10 TPE boiler in my small country house. I’ll say right away that the presence of a hob captivated me, and the price for a pensioner is very affordable. I heat with wood, I have to refill it about once every 5 hours, they burn out pretty quickly. I would switch to coal, but we have problems with it. In principle, I am satisfied with the device, quite acceptable quality for the money.

Igor Nikolaevich, Khabarovsk

As you can see, Sibir KVO floor-standing boilers are ideal for a summer residence, due to the fact that it can be used not only as a heating device, but also as a cooking stove. And if you visit the dacha only on weekends, heating elements will allow you to avoid freezing of the coolant in your absence.

Household heating boilers "Siberia" Hephaestus

The Siberia Hephaestus boiler is a new product on the domestic heating equipment market. It has been produced since 2014, but can already compete with devices that have been on the market for a long time, such as the Dakon solid fuel combi boiler. A total of three standard sizes are available for 15, 20 and 30 kW.

Like any other classic solid fuel boiler, the “Siberia” Hephaestus has a firebox surrounded by a water jacket. Under the grate there is a spacious ash pan for collecting solid waste. Flue gases are discharged through a pipe at the rear of the boiler into the chimney. In addition to these generally standard units, there are also some features:

• As a backup heating source, it is possible to install a 4 kW heating element. It can be used to stabilize operation between loads and to preheat the heating system in the absence of the owner.
• There are supply and return pipes on the left and right walls of the boiler for ease of installation and piping. The unused supply line pipe is closed with a plug, and a 4 kW heating element unit can be installed in the free return pipe.
• To control the combustion process, you can optionally install a mechanical draft regulator. A separate output is provided for its installation on the front panel. The sensor measures the water temperature in the boiler and, if necessary, opens or closes the ash pan damper using a long chain.
• To increase efficiency, the grate bars are filled with water. Beams with coolant inside the loading chamber are used for the same purposes.
• Under the top cover of the boiler there is a round hole leading into the firebox. It can also be used to load the boiler with fuel, as well as to install a pan or other kitchen container.
• The boiler casing is covered with wear-resistant paint, and on the front panel there is a thermometer for visual monitoring of the temperature of the solid fuel boiler.

“Siberia” Hephaestus works exactly the same way as a conventional water-heating wood-burning boiler. Let's take a closer look at its characteristics:

On a thematic forum we found a thread with discussions about the “Siberia” Hephaestus line, and here’s what people are saying about them:

Hephaestus installed 30 kW on the terrace of his country house. House 180 m² made of blocks, double-glazed windows. It heats up fine, but it's not particularly hot. Of course, you have to throw it often; one thing that saves you is the terrace nearby. In short, the device is not without its shortcomings, but for that kind of money, I think it’s better not to buy it.

Anatoly Vladimirovich, Rostov

In terms of price-quality ratio, the “Siberia” Hephaestus is a pretty good model, and is suitable where a budget heating system is needed that does not involve serious loads. In other cases, it is better to buy a more serious boiler.

As a video review, watch a short video from YouTube about the Siberia KVO boiler:

produces mainly budget modifications of household solid fuel boilers. If you do not need an expensive multifunctional device, but need a cheap heating device with a minimum set of functions, then we advise you to pay attention to the Siberia boiler range.

Specifications

Design of a solid fuel boiler
Before choosing a suitable boiler model, you need to study its technical characteristics in detail. Each model has its own designation. For example, KVO 12 TPE: the number indicates power, the letters indicate a device with an electric heating element operating on solid fuel. The thermal performance of devices is measured in kilowatts and varies between 12-20 kW, efficiency is 70%, standard pressure cannot be more than 0.1 MPa. Using devices from both series, you can heat rooms with an area of ​​120 to 200 m2. The maximum temperature value should be at least 95 degrees, the nominal value should range from 60-80 degrees.

The diameter of the Siberia boiler chimney should be 150-200 mm, the power of the unit is 2 kW. Compliance with all technical requirements during installation and operation ensures stable operation of the boiler. Drinking water with a GOST 2874 value is used as a heat carrier, the hardness of which cannot exceed 0.7 mg. The water treatment option must be selected by the project company. In addition to water, it is allowed to use household heat carriers permitted for residential premises.

For safety reasons, it is prohibited to use antifreeze containing ethylene glycol and other liquid components not intended for heating systems.

Solid fuel heating boilers Siberia and gas boilers Siberia

By name, the solid fuel and gas heating boilers SIBERIA and SIBERIA are very similar, but these are different units, or rather, they are produced by different manufacturers and, of course, use different types of fuel.

KVO SIBERIA is produced by the EUROMASH Group of Companies;
• SIBERIA gas appliances are manufactured at ZAO Rostovgazoapparat.

Heating boiler SIBERIA of various modifications

So, despite the great similarity in names, these are still different heaters. We will try to present to you the general technical characteristics of both models and in addition we will show a video clip that will complement this topic.

SIBERIA and SIBERIA

KVO SIBERIA

Note. KVO SIBERIA are designed for residential and non-residential premises with ceilings up to 2.7 m and an area of ​​up to 200 m 2. It is possible to connect heating with an open circuit (radiators or registers) and pressure up to 1 atmosphere.

Construction of a solid fuel unit

• A very important advantage of such a boiler is its accessibility and this is possible due to the fact that it is easy to use and all models, in fact, have a budget price . Convenience and ease of use are perfectly combined with maximum use of the thermal energy produced by the device.
• Modest dimensions make the models compact, and this allows you to build them in with your own hands without much interference with the interior in a variety of rooms.
• In addition, the device includes an electrical unit with 3 kW heating elements installed in it . This makes it possible to maintain the coolant in a hot state while the firebox is extinguishing, for example, at night.

Table of technical characteristics of KVO SIBERIA

Note. At a low combustion temperature of fuel (for example, damp wood), there is a danger of a large amount of soot settling on the chimney, which, without timely prevention, can lead to a fire. If the combustion is too intense, there may be a risk of water boiling in the boiler.

KVO 10 TPE. Photo

When purchasing such a unit, you will come across an abbreviation that has a certain meaning. So, KVO 10 TPE means that this is a Cooking Heating Boiler, with a power of 10 kW, Solid Fuel, there is a Cooking Stove, an Electrical Unit with heating elements.

To independently calculate the area of ​​the room relative to the boiler power, the following instructions will suit you. If the ceiling height in the house does not exceed 270 cm, then in this case you will need 1 kW of heater power per 10 m2 of room. For example, your house will have 70m2, which means 70/10=7kW - in this case, the KVO SIBERIA 10 model is more than enough for you.

Advantages and disadvantages

The NMK plant produces boilers from high-quality raw materials.
Each Siberia heating boiler, regardless of the model, has its pros and cons. In the list of advantages, consumers include high-quality raw materials from which the devices are made. The main advantage of the units is also their reliability and durability, a large assortment and choice of options, affordable prices and the ability to purchase the desired model in every region of the country.

Products of the brand are able to function properly in any weather conditions, including extreme heat and frost. Each boiler is accompanied by the necessary documents: certificates of conformity, instructions for use. A standard solid fuel boiler of the Siberia brand has practically no drawbacks, with the exception of minor difficulties during the installation process, which depend on the characteristics of the room.

Types of boilers Siberia

Steel heating boiler Siberia KVO 10 kW
The NMK enterprise produces solid fuel units KVO and Hephaestus. Each series includes a set of models that have their own characteristics, differences, advantages and disadvantages.

Siberia KVO

Steel appliances of the KVO series are created for owners of country houses and dachas who are looking for budget household units. The list of devices in the series includes five types, marked with numbers 10, 12, 15, 20 and 25 according to the number of kW of power. All of them are made of heat-resistant steel, some are supplemented with cast iron elements. Each boiler is equipped with special parts:

• water-tube grate of grate type;
• cross beams with heat carrier;
• lid combined with the hob;
• additional heating element for 3 kW, installed separately.

The connections for flue gases, supply and return lines in models of this series can be located on the right or left wall for more convenient installation. The operating principle of such boilers does not differ from standard combustion appliances; they operate on wood or coal, which heats the coolant inside the heat exchanger.

Siberia Hephaestus

Solid fuel boiler Siberia Hephaestus KVO 15 TE
Devices of the Hephaestus series have been produced since 2014, they are new products in the field of heating equipment. Consumers can purchase a unit of one of three types with a capacity of 15, 20 or 30 kW. The firebox of each boiler is surrounded by a water jacket, the grate is complemented by a deep ash pan that can accommodate a large amount of waste. Boilers of this type have their own characteristics:

• the ability to supply a 4 kW heating element as an additional heating source;
• the presence of supply and return pipes for more convenient piping and installation work;
• the ability to install a mechanical traction regulator;
• water tanks in grate bars to improve operational efficiency.

Double-circuit and single-circuit boilers of the series function similarly to standard water heating devices. This is a good option in terms of cost-quality ratio, suitable for those who stick to a budget when creating an indoor heating system.

Hephaestus boilers are not suitable for heavy loads and are of a lightweight type.

Installing the device yourself

The floor and walls near the boiler must be protected with non-combustible materials.
The boiler and other elements of the heating system must be installed taking into account compliance with safety rules. The device is mounted at certain distances from combustible elements, maintaining a distance of at least 500 mm from the walls of the boiler. There must be at least 1200 mm of space from the top of the floor-standing boiler and the ceiling, and at least 1250 mm from the wall in front of its door. If a wood-burning or heated floor is made of flammable materials, a fire-retardant coating is made of sheet steel laid on a layer of asbestos cardboard, which is impregnated with a clay solution.

Valves or safety devices are placed in a part of the output manifold device without intermediate elements. In this case, the supply pipes cannot be less than 32 mm. The heating system is installed so that the air is completely removed when it is filled, and the coolant is eliminated through the drainage when the device is emptied. The heating element unit must be connected using a cable with 30 A circuit breakers, the cross-section of the copper wire in which must be at least 4 mm2.

Operating principle

Due to their simple design, Siberia units allow you to save a lot and reduce fuel costs. They work on the principle of using a closed firebox, which limits the flow of air into the chamber. By creating the effect of “oxygen starvation” during operation, the fuel burns 3-5 times longer than in standard mode. Just a couple of loads of fuel will be enough for one day if firewood is used. With the help of coal, the boiler can operate for more than two days.

Siberia boilers have a high efficiency, reaching 90% - this is an ideal indicator for solid fuel appliances.

Siberia Hephaestus

The Siberia Hephaestus boiler is a new product on the heating equipment market. The company began production of these models in 2014, but in a short time, Hephaestus units were able to consolidate their positions and win the love and trust of users.

Models with a power of 15, 20, 30 kW are available. Like any other type of classic solid fuel boiler, this unit is equipped with a combustion chamber, which is surrounded by a water jacket. Under the grate there is a spacious ash pit where waste accumulates. Flue gases are discharged through a pipe located at the rear of the boiler into the chimney.

Operation and Maintenance

During use of the system, the level of the coolant in the open tank cannot fall below its height. By adding coolant, it is maintained at the optimal level. Water from the heating system cannot be used for domestic purposes; this can stop circulation and reduce the liquid level. Before turning it on, it is necessary to open the dampers on the chimney, check whether the tap on the return line is open, and also take into account the presence of draft.

During ignition, the device is heated with dry wood, loading it inside the firebox up to half its height. Hot coals should completely cover the grate; the coal is loaded gradually when the firewood is perfectly lit. Coal fuel must be placed into the firebox through the door in small portions, without leaving the hole open for a long time. After the coal is ignited, the ash pit door is left in a position that ensures complete combustion of the fuel. During initial ignition, dark liquid may leak from under the ash drawer.

You need to clean the grate at least once a day. Do not allow a large accumulation of water inside the firebox; cleaning is carried out at least 1-2 times a day.
