Which is better to choose a boiler on the chips for the house?

Solid fuel boilers, even with the advent of energy efficient gas heating stations, have not left their positions in the market. They are also in demand due to the usual design, reliability and performance. For home use it is one of the best ways of heat supply. But inside the segment there is a competition between the units of different types. Classical coal, wood and combined systems are opposed to a chip boiler, featuring an optimized design and wide functionality.

Features of the boiler on chips

Compared to conventional solid fuel boilers, models operating on wood chips have differences in raw materials handling systems and distribution of heat fluxes. To load sawdust or chips, a special hopper is used, from which the material is delivered to the combustion chamber. When the cycle of thermal processing is completed, the waste is sent to the appropriate collection. Despite the presence of new functional units, the design has a modest size. Usually these are compact units with an ergonomic control system, designed for use by non-professionals. Already in the initial segment boilers on the chips for the house are provided with electronic control systems with automation. The aforementioned loading process, in particular, is controlled by sensors. The user can learn about the parameters of the workflow through a special display.

As for the direct function of providing heat, it is realized using the contour infrastructure of hot water supply. In the design of the unit there is a whole compartment with heat exchangers, which are connected to the domestic pipeline. That is, the heating boilers on the chips can replace the function of the boiler installation, although this possibility is fully available only to high-performance models.

Types of aggregate

Such boilers are divided according to the possibilities of working with other heating materials, levels of automatic control and the number of circuits. As far as possible the loading of fuel raw materials, standard and combined models can be distinguished. The first type is specially designed for working with sawdust, chips and chips. Combined modifications also allow the use of pellets and other biofuel pellets. Interesting and classification of automation systems. In the simplest versions, the boiler on the wood chips realizes the semi-automatic supply of fuel to the combustion chamber. The most developed devices allow to fully control the microclimate parameters in the heating rooms. For this, boilers are supplemented by thermostats with remote sensors. As for the circuits, the basic modifications include open air heating, and several heat exchange lines allow the equipment to be used both as water heating equipment and for cooking.

Basic Selection Parameters

The basic characteristic of a modern boiler is power. In many ways it also defines all other parameters. For a small house, you can confine yourself to a model with a power potential of 40-50 kW. Multifunctional water heating equipment for a private two-story house can work with a power of about 90 kW. Further, the material of manufacture is determined. Here the choice is between cast iron and steel units. Models of the first type are positioned as durable, but if suddenly for some reason the body is damaged, then it will be impossible to restore it. The steel boiler on chips is not initially as strong, but in case of deformation of the structure or the formation of a crack, it can be repaired by welding.

Should I choose models with prolonged burning?

The concept of long-term combustion assumes the presence of a more voluminous combustion chamber and a secondary combustion system. A so-called pyrolysis effect is realized, which involves not only thermal processing of the main fuel material, but also the combustion of the separated gas particles. In this case, the boilers on the chips of long burning are installed only on the floor because of the impressive dimensions and the corresponding mass. The expediency of acquiring such an assembly takes place if it is planned to serve large areas of heat. The boiler is characterized by a combination of high performance and fuel economy, which indicates its energy efficiency. But for a small house, there is no sense in such an acquisition - in any case, a compact wall-mounted unit from standard series will not less adequately cope with the tasks of heating.

Best producers

The most widely represented segment is represented by foreign companies, including Froling, Buderus, Hargassner, ETA, etc. These manufacturers implement powerful boiler plants with modern automation and advanced functionality. However, there is a solid fuel boiler on chips of imported origin not cheap. Models for a country house, for example, are estimated at 60-80 thousand rubles. average. Domestic manufacturers of heat equipment, like the Teplodar, Mister Hit and Danko companies, offer more affordable solutions, the cost of which can fit into 30-40 thousand. However, the technological development of Russian units is not so high compared to foreign competitors.

Conclusion

If we compare this type of boiler with alternative methods of heating, then there will be many questions about the benefits that can be expected with this choice. On the one hand, it can be high ergonomics with automatic control, and on the other - energy efficiency, supported by the possibility of universal use of the boiler. What will have to be sacrificed, buying a boiler on chips? The main disadvantage of such equipment is the maintenance and preparation of fuel raw materials. Such boilers are very capricious and demanding on the characteristics of the same chips. The feed material must be thoroughly dried, and in some cases also pre-machined.
