Modern solid fuel boilers are very different from their predecessors. Simple design and stable operation make them irreplaceable elements of autonomous boiler rooms. It is believed that cast iron devices last the longest. Such equipment is produced by many domestic and foreign manufacturers. Among them is the Proterm brand Bober solid fuel boiler.
Features of boilers Beaver
The main distinguishing feature of Bober Proterm heating devices is their sectional structure. The body is made of separate elements that are fastened together. The boiler parts are cast from high quality cast iron.
The assembled structure is a heat exchanger framing the firebox. The original shape allows the temperature to be evenly distributed over the entire space of the combustion zone. This reduces the risk of temperature extremes, overheating and low temperature corrosion.
Other features:
- large heating area of the coolant (two-pass heat exchanger);
- suitable for heating residential and industrial buildings;
- it is possible to connect an external boiler for heating service water;
- the cooling circuit protects the system from critical temperatures;
- open combustion chamber (takes air from the room);
- ease of installation and operation;
- mechanical power adjustment;
- 2 years manufacturer's warranty.
Traction control methods
Boiler Protherm power adjustment is carried out in mechanical and manual modes using three devices.
Control devices:
- TPM (thermomechanical power regulator);
- flap on the combustion chamber door;
- chimney draft limiter.
TPM adjusts the primary air supply under the grate. The unit is located on top of the body and is connected by a chain to the blower door. The required coolant temperature is manually set on the regulator. To maintain it, the device adjusts the degree of opening of the damper. When the temperature drops, the chain stretches and the blower swings open. If the hearth is too hot, the chain is loosened and the door is closed. In this way, control over the intensity of combustion is achieved.
The air fungus on the firebox door regulates the access of secondary air directly to the hearth. Adjustable in manual mode.
The chimney damper is responsible for the draft in the chimney. It is not possible to operate the boiler in a fully closed state. The more the damper is open, the stronger the draft and the more intense the combustion in the hearth.
To monitor the parameters of temperature and pressure, a thermomanometer is located on the front panel.
Benefits
The main plus of Protherm Bober solid fuel boilers is their efficiency. The special design allows efficient use of the fuel resource.
Other benefits:
- simplicity and reliability: prefabricated sectional design allows you to replace individual parts in case of failure;
- high efficiency up to 80%: achieved due to the large area of heat removal;
- durability: a cast-iron heat exchanger can last for decades;
- non-volatility: the device does not require electricity to operate;
- safety: a built-in thermostat protects the unit from overheating.
disadvantages
Bober Proterm devices have disadvantages that may be significant for some buyers.
Their disadvantages:
- short burning time of one bookmark (2-4 hours);
- the need to constantly be on duty at the boiler (put fuel on, throw out ash);
- front loading only (inconvenient to fill coal).
The advantages of the work and the device of the boiler
The advantages of Protherm boilers of this series of solid fuel boilers include the following points:
- Cast iron heat exchanger. Structures made of this material are resistant to corrosion processes. Their use in heating boilers makes it possible to significantly increase the operating period of the device.
- Electricity independence. There is no need for a network to operate the boiler and control the combustion of solid fuel. Therefore, the Beaver boiler can be installed far from electrical transmission lines.
- Mechanical draft regulator. It helps to automatically control and stabilize the combustion process. This process is carried out mechanically, no connection to the power supply is required.
The principle of operation of the Boiler Proterm Bober
What kind of fuel can be used
Bober Proterm heating units operate on coal with a fraction of 4 cm or more and wood.
The moisture content of the wood should not exceed 20%. Failure to comply with this condition reduces the power and service life of the device. When damp wood burns, soot and tar deposits accumulate in the boiler cavities. The length of the logs, depending on the model, is 32-68 cm. The diameter of the firewood is from 4 to 18 cm.
Operating time on one load of wood is 2 hours, coal - 4.
Reviews about the technical characteristics of the model

The popularity of solid fuel boilers has grown
Oddly enough, but this is really the trend today. Some time ago, it began to seem that solid fuel boilers would leave their "palm" in the 20th century, as they were actively being replaced by gas and electric heating systems based on automation. But the high cost of electricity and the inaccessibility of gas energy for quite a few remote settlements contributed to the preservation and even some increase in the popularity of solid fuel boilers. Probably, the increase in their rating is due to the improvement in the quality of equipment.
Firewood, charcoal and coal continue to be a viable alternative to gas. The market offers the widest range of models. So the problem of choice is more of a headache for today's users.
Installation and maintenance recommendations
Boiler equipment will last as long as possible, provided it is correctly selected and operated.
Choice
The power of the Bober boiler must correspond to the area of the heated building. It is believed that heating ten square meters of premises requires 1 kW of thermal energy.
When buying a unit with less output, it will not be possible to achieve a comfortable temperature in the home. With a slope upward, the prerequisites for premature failure will arise: the formation of condensation and resin in the cavities of the device. In this case, a dirty heat exchanger will not cope with its function.
Installation rules
Installation work must be carried out by an organization that has the necessary permits.
Features of the installation of equipment Bober:
- a place for a boiler room is chosen with an operating ventilation system in residential and non-residential (corridor, basement) rooms with a temperature of 5-35 ° C;
- the heat generator is installed on a non-combustible flat base: floor or foundation;
- the combustible base is preliminarily covered with a sheet of steel on the sides and in front, placing a fire retardant gasket under it;
- on the front side, leave a free space of at least 0.6 m for ease of use;
- behind and from the side for access to the nodes, an interval of 0.6 m to the wall is also used;
- the chimney and heating system elements are connected according to the instructions;
- carefully check the tightness of the connections to the heating pipes and the chimney.
Recommendations for use
Maintenance of heating devices Protherm Bober is carried out by the user and service specialists.
Basic rules of daily care:
- use small chips and paper for kindling, do not use flammable liquids and explosive substances;
- do not overheat the coolant above the maximum permissible parameters;
- do not lower the water temperature on the return line below 50 ° С;
- before adding a new portion of fuel, shut off the air supply to the hearth and wait for the smoke to be removed by opening the chimney damper;
- when performing manipulations with a working boiler, use protective thermal gloves;
- do not store fuel material near the heater at a distance of less than 0.8 m;
- clean the ash box several times a day so that the mass accumulated in it does not interfere with the flow of air under the grate;
- for collecting ash, fit containers made of non-combustible materials;
- once a month, clean the internal surfaces and the boiler chimney from soot;
- when resin accumulates on the walls, burn it out, heating the coolant to the maximum temperature;
- When the unit is shut down, clean it, lubricate the rotating parts and close the doors.
In addition to the above, it is necessary to carry out maintenance (maintenance) of the unit once a year. It is performed by a representative of the service company.
In the process of maintenance, the following is checked:
- functioning of control and protection units;
- the performance of the dampers;
- tightness of joints. Read the grundfos circulation pump in our article.
Installation and maintenance
For a long service life and stable operation of the Bober Proterm boiler, its correct installation and connection, as well as periodic cleaning, are required. Experts recommend:
- Install the heating unit in a non-residential area or in a room specially equipped for it, where an inflow of fresh air is provided.
- Mount the device on a lining made of non-combustible material or on a special foundation when installing in a basement.
- A minimum distance of 600 mm must be left at the front and rear. On one side, the same distance must be ensured for passage and unhindered access to the rear of the boiler equipment.
- The section of the chimney must be equal to or greater than the section of the outlet pipe. The chimney must be free of bends, and parts of the structure in the unheated area must be insulated. If several solid fuel boilers are used, it is forbidden to connect them to one chimney.
In addition, you also need to service the Proterm boiler from time to time. It is recommended to observe the following points:
- monitor and regularly clean the ash pan. If the niche is full, the air access to the combustion chamber will decrease;
- before starting kindling, remove all residues of solid fuel from the grate;
- at least once a month, it is required to clean the surface of the cast iron heat exchanger from soot and ash deposits. When the carbon layer is too thick, the heat exchange becomes lower, and, as a result, the performance of the solid fuel boiler decreases.
Solid fuel boilers Proterm Bober are designed for those who value simplicity and efficiency. They will work perfectly where most analogs of solid fuel units are not capable of functioning, for the operation of which an electrical network is required.
Pros and cons ↑
Among the main advantages, it should be noted high work efficiency and cost-effectiveness when using a coolant, low heat loss with high inertia and high efficiency. This is where the natural removal of combustion products takes place. Firewood can be loaded twice a day. The equipment will serve for a long time, since, being made of cast iron, it has high wear resistance, does not deform and corrodes little. Among the advantages, owners also note a large fuel chamber with convenient loading. As for the shortcomings, users in their reviews note the features of traction control, to which they have to adapt, as well as not very convenient cleaning of the boiler. The cast-iron unit Bober 20 DLO is difficult to move from place to place, there are a number of analogues that are much lighter in weight.
