Solid fuel heating appliances do not lose their relevance in the conditions of widespread gasification. Manufacturers annually update their range, offering more and more advanced models.
Foreign devices are rightfully considered more technologically advanced. However, they are very sensitive to operating conditions and can fail with small deviations from the norm. Domestic products are more reliable. Solid fuel boilers Zota Mix from the Krasnoyarsk plant have proven themselves well when working in harsh conditions.
Features of Zota boilers
Zota heating devices are designed specifically for use in temperate and cold climate zones. Despite the variety of models, boilers have some common features.
Features of the units:
- Strength. Made from high quality boiler steel.
- Versatility. Suitable for heating residential and industrial premises, open and closed heating systems.

How to choose the right boiler
When choosing a heating unit, the buyer should focus on his individual needs and capabilities.
Significant criteria:
- Available type of fuel resource. Depending on what you plan to heat the boiler with, choose a solid fuel or mixed option.
- Convenience. Operation should not cause difficulties for the user.
- Price. Usually they choose the most inexpensive of the models with similar suitable parameters.
- Power. It is believed that to heat an area of 10 square meters. m. requires an average of 1.5 kW of thermal power. For example, for a house measuring 100 square meters, a 15 kW boiler is suitable.
Types of boilers operating on solid fuel
All equipment of this class can be divided into 2 groups:
- Automatic fuel supply
- Manual loading
The first are pellet boilers. In them, granules play the role of fuel; they are loaded into special bunkers and from there they enter the furnace. Such devices have high efficiency and can operate automatically for weeks, without human intervention.
The latter, depending on the design features, are divided into 3 types:
- Classic
- Pyrolysis
- Long burning
They can use firewood and wood waste as fuel.
A traditional or solid fuel boiler using wood has been produced for a very long time, and its design has remained virtually unchanged. In it, the combustion chamber is located at the bottom and is considered the hottest part. Most often it is made of cast iron or steel. However, such heating of a wooden house with a solid fuel boiler is used quite rarely, as it requires frequent maintenance.
Pyrolysis devices are a new step in the field of solid fuel equipment. Their work is based on the principle of decomposing wood into solid residues and gases and burning the latter. The advantages of this device include high efficiency, minimal formation of ash and soot. Among the disadvantages is the need to burn dry wood with a humidity of no more than 20%.
Long-lasting combustion - their operating principle was developed in Russia and has no analogues in the world yet. It is a new generation boiler not only in terms of design, but also in its operating principle. Its main advantage is the simplicity of its design and the ability to service it once a day when operating on fuel with natural humidity. A solid fuel wood boiler has the most precise power control and can produce a given amount of heat.

Reviews of boilers from the “Zota Master” series
Solid fuel boilers "Zota Master", according to buyers, have a high degree of thermal insulation. The heat exchanger, which is built into the unit, is of a combined type. The body is insulated with basalt cardboard, and there are ventilation holes on the door trim, which are necessary to cool the surface of the device. Consumers like that the ash pan door has an air damper; it is equipped with a screw with a handle that can be used to regulate the flow of primary air.
It is worth noting that the efficiency of boiler equipment depends on the degree of gas density, as well as on the design of the heat exchanger. If we are talking about Master series boilers, they use a combined heat exchanger. It contains a pipe compartment, which, according to users, has reliable qualities and is easy to clean. The manufacturer has provided the possibility of installing a mechanical regulator. The boiler is capable of operating in semi-automatic mode. The assembly ensures the tightness of the door, as well as the accuracy of adjustment.
The described solid fuel boiler "Zota", reviews of which are often only the most positive, has a combustion chamber, it is designed for the most efficient combustion of coal. The device can also use firewood. If you choose a unit whose power is higher than the others, you can put 70 cm of firewood into it.
Reviews of boilers of the “Zota Mix” series
One of the most popular from the described manufacturer is the Zota Mix solid fuel boiler. It has an x-shaped heat exchanger design, with which it was possible to achieve maximum heat transfer area. This indicates better heat transfer and increased efficiency. Users note that heat loss is reduced due to the quality of the thermal insulation used. The boiler becomes less fire hazardous. The outer casing that covers the insulation is coated with powder paint; as the owners of such equipment emphasize, it is characterized by increased wear resistance. The manufacturer has taken care of the convenience of cleaning the equipment; for this purpose, there is a removable door on the front panel that provides access to the entrance. In order to get rid of combustion products, an ash drawer is provided; it is located behind the ash pan door.

Solid fuel boilers are an excellent solution for cottages and dachas where there is no possibility of gas supply. Fortunately, we have plenty of coal and firewood in our country and they are inexpensive. Therefore, we will consider one of the most popular models of medium-power solid fuel boilers - Topol M20 from Zota. Production - Krasnoyarsk, Russia.
The Topol M20 model is a modernized version of the regular Topol with a lot of improvements and modifications aimed at increasing combustion time and increasing efficiency and heat transfer.
The average price at the end of 2021 is 35,000 rubles, so this model falls into the category of popular budget boilers. The boiler power is clear from the model name - 20 kW. Zota is a Russian company that has long established itself in the heating equipment market.
We can see the main characteristics in the photo below:
As you can see, the area of the heated room is stated to be as much as 140 square meters; most people use Topol 20 for cottages of 90-150 square meters.
You can heat it with both wood and coal. Users more often, of course, use coal, and firewood only for kindling. After all, coal burns longer and heat transfer is higher. According to reviews, it is enough to load a 12-liter bucket of coal 2 times a day (in severe frosts -30) to maintain a comfortable temperature of 23-25 degrees in a room of 120 square meters.
IMPORTANT - the Topol model is intended primarily for the southern regions of Russia, where the temperature does not drop below -15. If you are choosing a boiler for the Central and Northern parts, for Siberia - then pay attention to specialized long-burning boilers - here, of course, Buderus is ahead of the curve.
Boiler features
The first way it differs from other models is its top loading. It is very convenient to add coal.
An extended firebox is another convenient design solution that allows you to load longer logs inside.
The only thing that disappoints is the rather thin walls. The wall thickness is 3 mm (if you take, for example, some models of Buderus boilers, the thickness is 5 mm), so when burning coal, it is not known how long the boiler will last, whether it will burn out quickly, and so on. Fortunately, I personally have a friend who heats his private house of 120 square meters with this particular model - Topol M20, the boiler has been in service for the second year and so far everything is fine. It heats with medium-fraction coal, sometimes with wood (when the coal runs out).
Operating time without loading, coal or pellets?
It is stated that the boiler can operate for up to 10 hours at full load. In reality, this figure is slightly lower, and only if the firebox is fully loaded with coal. But 6-7 hours is not bad at all.
Is it possible to burn with pellets? You can often see this question on forms from new Topol owners. The answer here is obvious - of course you can, it’s how much money you will waste - a lot. It is many times more efficient and cheaper to burn with coal, even with low-quality coal.
You can throw in huge pieces of coal (the main thing is that they fit into the firebox) and the boiler will heat and heat. Compare for yourself - a ton of high-quality coal costs 3,500 rubles, low-quality coal costs 2-2.5 thousand per ton. A ton of pellets costs as much as 6,500 rubles. The difference is already 2 times!
Boiler advantages
Disadvantages of the boiler
Topol boilers have a lot of disadvantages, but they all stem precisely from the cost - the boiler is a budget boiler and there is nothing to expect from it super-results, as from boilers that cost 2-3 times more. Steel is 3 mm, for such a price this thickness is exactly what it should be.
It smokes - there are a lot of comments precisely because the boiler smokes when you open the door to load the next portion of fuel. This can occur either due to poor draft (a problem with all boilers in general), or due to the diameter and height of the pipe, or due to the fact that the pipe is not insulated.
Well, and most importantly, it smokes due to the fact that the design of the chimney is such that the chimney pipes inside the boiler become coked (they are small in diameter - 50 mm and there are 8 of them) and they need to be cleaned often. So an indispensable attribute that you will need to use the Poplar boiler is a metal brush for cleaning pipes.
The scorching grate will sooner or later all burn out, because there is direct contact with burning coal, as a result, it becomes red-hot and burns slowly but surely. Although it is 1 cm thick, it is unknown how long it will last when fired with coal.
Settlements remote from civilization are not always supplied with natural gas, so property owners in such areas are looking for alternative heating options. There are quite a lot of them today, but diesel fuel and electricity are expensive, so modern consumers are increasingly turning their choice towards solid fuel. Many modern heating devices work on it, but foreign models do not correspond to domestic climatic conditions. Domestic products are in greatest demand among buyers. It is offered for sale by different enterprises, each of which produces boilers with certain features and characteristics.
For reference
If you purchase a Master-20 brand boiler, it can be supplemented with a gas burner, which will make the equipment more versatile. Each device can be equipped with a heating element, the capacity of which is 9 kW.
- The boiler body has become thermally insulated and more gas-tight. The water jacket of the boiler under the decorative casing is now covered with basalt cardboard, which has significantly reduced heat loss. The fire door opens in a horizontal rather than vertical plane and is locked with a lock. The ash pan door is equipped with a blower damper, which is adjusted manually using a screw or controlled by a mechanical draft regulator, which is installed as an option. Thus, the increased gas density of the boiler makes it possible to more accurately regulate the oxygen supply and extend the fuel combustion cycle on one load to 10-12 hours.
- the combustion chamber has undergone changes: an additional horizontally located heat exchanger in combination with a removable damper makes the gas duct a three-pass one. This increases the heat transfer area and improves heat transfer efficiency. The damper is made removable specifically for cleaning the heat exchanger. In addition, there is a cleaning hatch on the flue, which makes it easy to remove soot.
- A thermometer is installed on the top panel of the boiler to measure the temperature of the water supply.
- Topol M uses coal and wood as fuel. As an alternative, electric heating is possible, which is provided by a built-in heating element with an external control panel (installed upon request and is an option). It is also possible to install a gas burner in place of the screw door. In addition, the presence of a screw door creates additional convenience for loading firewood into the firebox. The depth of the firebox ranges from 38 to 58 cm. A separate ash door allows you to remove ash at any time while the boiler is firing. For user convenience, new ergonomic handles are installed on all three doors.
- Due to the design features of the fuel combustion chamber, increased gas density and quality of workmanship, the Topol M series of boilers has the highest efficiency among budget models of solid fuel and combined boilers.
- possibility of additional installation of the “TENB 2” kit.
