Solid fuel heating boiler Proterm Bober 20 DLO: technical characteristics, price, owner reviews

Modern solid fuel boilers are very different from their predecessors. Simple design and stable operation make them indispensable elements of autonomous boiler houses. It is believed that cast iron devices last the longest. Such equipment is produced by many domestic and foreign manufacturers. Among them is the Beaver solid fuel boiler of the Proterm brand.

The popularity of solid fuel boilers has increased ↑

Oddly enough, this is really today's trend. Some time ago, it began to seem that solid fuel boilers would leave their “palm of championship” in the 20th century, as they were actively being replaced by automatic gas and electric heating systems. But the high cost of electricity and the inaccessibility of gas energy for quite a few remote settlements contributed to the maintenance and even some increase in the popularity of solid fuel boilers. Probably, the increase in their rating is also associated with an increase in the quality of equipment.

Firewood, charcoal and coal continue to be a viable alternative to gas. The market offers a wide range of models. So today's users are faced with more headaches when it comes to choosing.

Reviews of the 60DLO boiler

An alternative solution is the 60DLO model, which consumers consider equipment with high heating power. The latter parameters reach 48 kW. The device is used in closed heating systems. The combustion chamber has an increased volume, which, as buyers emphasize, allows you to extend the operating time of the heating system.

The design provides for a thermomechanical power regulator, which is required to adjust the heating temperature. Operation requires the use of solid fuel, it can be wood or coal. To maintain a certain heating temperature, the manufacturer equipped the installation with a thermostat.

Buyers like that overheating of the coolant is eliminated due to the presence of a cooling circuit in the design. If you wish, you can separately order a boiler, which is used to prepare hot water.

Installation and Maintenance

For a long service life and stable operation of the Beaver Proterm boiler, it requires proper installation and connection, as well as periodic cleaning. Experts recommend:

1. Install the heating unit in a non-residential premises or a room specially equipped for it, where a flow of fresh air is ensured.
2. Mount the device on a lining made of non-combustible material or on a special foundation when installing in a basement.
3. At least a minimum distance of 600 mm must be left at the front and rear. On one side, it is necessary to provide the same distance for passage and unobstructed access to the rear of the boiler equipment.
4. The cross-section of the chimney must be equal to or greater than the cross-section of the outlet pipe. The smoke exhaust pipe must be without bends, and parts of the structure in the unheated area must be insulated. If several solid fuel boilers are used, it is prohibited to connect them to the same 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 overcrowded, air access to the combustion chamber will decrease;
• before starting the kindling, you should remove all solid fuel residues from the grate;
• at least once a month it is necessary to clean the surface of the cast iron heat exchanger from soot and ash deposits. When the carbon layer is too thick, heat exchange becomes lower and, as a result, the performance of the solid fuel boiler decreases.

Proterm Beaver solid fuel boilers are designed for those who value simplicity and efficiency. They will work perfectly where most analogues of solid fuel units, which require an electrical network, are not able to function.

Pros and cons ↑

Installation: specifics and nuances ↑

Installation of the Protherm Beaver 20 DLO is possible not only in a residential area, but also, if necessary, in a utility room. It is installed in the basement, boiler room, corridor (at worst). The main thing here is to ensure the flow of air necessary for free combustion and to check the presence of a combustion product removal system. For safety reasons, the equipment must be installed on a fireproof base.

IMPORTANT: Installation of the boiler should be entrusted to specialized organizations that have the appropriate licenses.

Recommendations for installation and maintenance

Boiler equipment will last as long as possible, provided it is properly selected and used.

Choice

The power of the Beaver boiler must correspond to the area of ​​the heated building. It is believed that heating ten square meters of a room requires 1 kW of thermal energy.

When purchasing a unit with a lower output, it will not be possible to achieve a comfortable temperature in the home. If the slope is greater, prerequisites for premature failure will arise: the formation of condensation and resin in the cavities of the device. In this case, the contaminated 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 installing Beaver equipment:

• a place for the boiler room is selected with a functioning ventilation system in residential and non-residential (corridor, basement) premises with a temperature of 5-35 ° C;
• the heat generator is installed on a non-flammable, level base: floor or foundation;
• the combustible base is first covered with a sheet of steel on the sides and front, placing a fire-retardant gasket under it;
• a free space of at least 0.6 m is left on the front side for ease of use;
• from the rear and side, for access to the nodes, an interval of 0.6 m to the wall is also used;
• connections of the chimney and heating system elements are made according to the instructions;
• carefully check the tightness of connections with heating pipes and chimney.

Recommendations for use

Maintenance of Protherm Beaver heating devices is carried out by the user himself and service specialists.

Basic rules of daily care:

• use small wood chips and paper for kindling, do not use flammable liquids or explosive substances;
• do not overheat the coolant above the maximum permissible parameters;
• the water temperature on the return line should not be lower than 50 °C;
• before adding a new portion of fuel, shut off the air supply to the fireplace and wait for the smoke to clear by opening the chimney damper;
• When manipulating a working boiler, use protective thermal gloves;
• do not store fuel material near the heating device 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;
• to collect ash, use containers made of non-combustible materials;
• once a month, clean the internal surfaces and chimney of the boiler from soot;
• if resin accumulates on the walls, burn it out by heating the coolant to maximum temperature;
• When turning off the unit, 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.

During the maintenance process the following is checked:

• functioning of control and protection units;
• performance of dampers;
• tightness of joints. Read our article about the Grundfos circulation pump.
