Combined heating boiler

Combined boilers for home heating: types, characteristics and selection rules

In private homes and cottages, located outside the city, the best solution would be to use a combination boilers for heating houses. They would provide a comfortable temperature in all rooms, regardless of the presence or absence of a centralized gas or wood.

In addition, these systems help to varying cost estimates not only for heating the building, but also on the supply of hot water. They are recognized as the most effective in the absence of access to the central system supply of energy resources.

The main types of combined boilers

Heating equipment combined type is focused on downloading and processing of two or more types of fuels. More than 70% on the market models are equipped with special electric heaters, contributing to a partial or complete failure of the involvement of the main heating elements to heat the water in the summer season.

Kind of fuel material used allows equipment be divided into 2 main groups:

  • standard - use no more than two different types of fuel;
  • universal - capable of operating in three or more embodiments of fuel.

In most cases, it appears possible to replace the burner to change the fuel supply function. On sale there are also models equipped with hobs and even two burners with electronic or electromechanical type control.

The catch here is one - the more extended the functionality of the unit, the more difficult it will be the process of installation.

Features combined boilers

The owners of country houses, in which heating is provided a combined boiler, in one voice declare its indisputable advantages. Especially if the house is located far from major population centers, and the lack of gas supply and frequent power outages are the norm in this area.

In addition, the combi boiler, which is also called a universal, has many other advantages. They allow you to compete with the most popular kinds of one-component systems:

  • the ability to connect several circuits simultaneously;
  • a wide range of resources for technical modernization - replacement of burners, installation of the boiler;
  • the current level of program management;
  • no interruption in the heating system - at the time of outage of one of the fuels is possible to apply the alternative option;
  • economical consumption of resources to ensure the heating system.

Models with electromechanical control will be simply irreplaceable in the houses located in areas frequently experiencing electricity shortages.

Such an embodiment allows, if necessary translate boiler system in the manual mode, without losing the efficiency of its operation.

Popular variants fuel combination

Different variations of the combined heating units make it possible to solve all sorts of problems - from large-scale to less global problems. For example, they can provide hot water as a single family of 3-5 people, as well as heating of an office building or block of flats.

Option # 1 - combination gas / electricity

For the most efficient heating of water is electricity. The rapid increase in temperature produced by the action of the coolant on at least the delay fraction.

Features combined heaters that provide significant advantages:

  • small size. The device has an oversized combustion chamber for the combustion gases, the heat exchanger with built TAN or other type of heating device;
  • Low electricity consumption. The boiler operates in a gas heater and a start operation only on request - for quick heating of the water or in the absence of access to the gas supply;
  • Low price category. It is achieved due to the absence of separate combustion chamber - a heater installed within the heat exchanger. In equipment where no secondary circuit connecting the heater is planned embodiment;
  • with a small capacity of the heating elements - many presented on the model of the market, it is only designed to support the said evap.

Although the gas belongs to the economical type of fuel, an electric power is impossible to say. Therefore, for the houses located in areas with poorly developed gas supply network, should keep an eye on another version of the boiler running on other fuels.

Option # 2 - a combination wood / gas

More economical fuels and wood gas are considered. The dimensions of the heating device running on such fuel, impressive - he has for each of the fuel types are separate combustion chambers.

Design features of boilers with a combination type gas \ cleaved determine the placement of one or two heat exchangers. For the first case it is a common element for all combustors.

In a two-circuit boiler is only one type of fuel is used to provide hot water. This type of combined boiler requires preliminary resolution to issue documentation for installation.

In addition, these boilers are separated for two subspecies: the general and separate combustion chamber. The first option refers to the installation, create your own. They are used to minimize the total cost estimates for the maintenance of the heating system of a country house.

The hands produced gas burner assembly in the classical model of the boiler, if the solid fuel is used, it is dismantled. This embodiment creates unacceptable for heat exchanger operating conditions - exposure to high temperature during operation of the burner. It was she who is a frequent cause of violations of the boiler efficiency.

The construction with separate chambers of the furnace is equipped with two circuits, one of which is used to heat water for heating and the other - to provide hot water.

Option # 3 - a combination wood / electricity

Boilers for solid fuels is most often used when it is impossible to connect the main gas cylinders provide the arrangement or heating. They have more power and are nonvolatile.

Structurally, the type of combination boilers wood / electricity are quite similar to the gas model. Also available, and independent production of this type of device. PETN necessary capacity will be sufficient to determine and mount it to the heat exchanger.

In addition to these characteristics it is necessary to note the following features of the combined boilers working with wood and electricity:

  • auxiliary possibilities - PETN connection unit via a contact area with a temperature controller or a special programming unit providing remote control operation of the boiler;
  • increased resistance to breakage - factory provide heating by operating the heating elements (heating elements), which can withstand high thermal effect during operation of furnace chamber;
  • maintainability - upon failure of the electrical part of the boiler, it can be easily replaced. In many models, the gas heat-generating installations such feature is not available.

Power solid fuel boiler is regulated relatively slowly. In connection with such a feature for quick adjustment of heating level manufacturers recommend use electronic part teploustanovki.

Option # 4 - multifuel installations

Design features multi-fuel heating equipment for residential use are based on the use of several alternative fuels. Such heating systems include a combination of model beads pellet / gas / wood / electricity.

The most significant structural feature of pellet combined boilers - equipping multiple combustion chambers, adapted for engaging one of the fuels - a solid or liquid.

In addition the functional possible assembling of the electric heating element, located in the chamber of the heat exchanger.

Due to the easily removable pellet burner becomes possible to use other fuels, such as diesel or gas. For application of this kind of energy needed to create the conditions forced draft pressure and certain structural features of the heat exchanger. All these features are characteristic of pellet boilers species.

Multi-fuel heating system can be installed only after such requests:

  • Uninterrupted power supply - a prerequisite for the revitalization of pellet boiler, diesel and gas burners (use of solid fuel material is excluded);
  • Organized supply of fuel materials to the boiler - this is the most acute problem in the design of the installation of boilers with a combination gas / wood / electricity;
  • Providing energy storage locations - to use a balloon mounted external heating boxes of steel or allocate a separate room, and in some cases the building; diesel is saved in tanks connected to the pump unit.

Before purchasing a universal heating equipment necessary to carry out analysis of key factors influencing the selection of a particular model. So, should evaluate the usefulness of each type of energy source, because the cost of such a device is considerably higher mono-fuel systems.

What you need to know to choose the right?

The only objective criterion for the selection of the combined boiler for your home - the necessary power for the operation of the heating system. Moreover, this measure should not affect the number of connected loops.

It makes no sense to pay more for a powerful pot in hopes of adjusting its work automation. This approach helps to "idle" the instrument, which leads to more rapid failure. In addition, a similar operation to accelerate the condensation process.

With regard to the calculation of power, theoretically for heating an area of ​​10 m2 will need to use 1 kW of heat energy. But this is a fairly conventional index, which is adjusted on the basis of:

  • ceiling height in the house;
  • the number of floors;
  • the degree of insulation of the building.

It is therefore advisable to use in their calculations bonder ratio, ie calculations increase margin of 0.5 kW. Power multiloop heating system is calculated with allowance of 25-30%.

For example, to heat the building, the area of ​​which is equal to 100 m2 will require capacity of 10-15 kW with single-circuit heating coolant and 15-20 kW - for a bypass.

No less important criterion when choosing a combination boiler - this price category. The price of the device depends on the capacity, the number of features and manufacturer.

For users not less important, and other characteristics:

  • DHW;
  • manufacturing material;
  • easy to manage;
  • dimensions;
  • accessories;
  • weight and mounting features;
  • other.

Immediately have to solve the problem with hot water: to provide hot water to the boiler, or for that there is a boiler. In the case of determining the first embodiment, selects a more preferred method - or cumulative flow, and also the parameters of the water reservoir according to needs (calculated from the quantity of living).

As for the size of the equipment, they are only meaningful in the case of indoor installation with a small area.

Material for the manufacture of a wide range of boilers. But the most popular options - steel or cast iron. Also, such a boiler capable of withstanding high and continuous thermal stress, has a higher service life.

Automation of management affects the usability and security of the system depends on how automated the process of combustion energy. Most models can be operated using the convenient remote control panels or panels.

Most models of different additional equipment. These include the presence of a cooking surface for cooking, injectors, traction controllers, burners, a sound enclosure etc.

Choosing the boiler for this parameter should be based on personal preferences and the amount appropriated for the purchase.

But the weight of the equipment and the complexity of its installation should immediately pay attention. Installation of a residential building in the majority of floor models combined boilers for heating systems, equipped with several combustion chamber requires additional devices concrete pedestal, because a standard floor covering will not be able to withstand such a load.

Knowing the basic parameters affecting the choice of combi boilers, we can choose the most appropriate model

Combined heating boilers: features, types, how to choose

One of the main concerns of the homeowner - heating. And a lot of requirements: it must be reliable, cost-effective, does not deliver a hassle to use and more affordable. Practically impossible combination of characteristics. Meanwhile, however, the campaign, engaged in manufacturing heating equipment, trying to meet them at-least partially. For example, more and more it appears on the combined boiler market. From conventional units distinguished by their ability to use several different types of fuel. And the combination of already meet the most varied. Today, there are units that operate on three, and some models - on all four types of fuel: solid, liquid, gas and electricity.

Multifuel units have several burners for different fuels. Usually one charged coal or wood, the other is for liquid or gaseous fuels: gas or diesel. Several furnaces for different fuels good that it can be connected to several separate independent circuits and the temperature in them can be different. For example, one maintains the battery, and the second - a warm floor. A separation per floor or even on any other principle. If you like this idea - buying a note of the fact that each was a separate heat exchanger of the furnace, that is, not in all the boilers.

Combined heating boilers are usually several burners for different fuels may also have several independent coils

If we talk about the developments of recent years, almost all modern models are even built-in heating elements. It turns out, this equipment makes it possible to work on any existing currently fuels.

Another interesting novelty: designed burners that may be used with equal success gas or diesel oil (in any case, so say manufacturers). With this spray unit is not necessary, even in burners or two chambers. The type of fuel varies transfer switch in one of the positions.

For a more economical and efficient heating of large areas and reduce the cost of heating, it is desirable to apply heat accumulators. This is particularly advantageous when the regular use of wood and coal, as one of the fuels. This is due to a feature of multi-boiler: capacity boiler using solid fuels is not regulated and the room becomes sometimes too hot. In the presence of excess heat heat storage assigned thereto and where "canned", and the shortage of the thermal energy of the hot water storage tank is fed in or goes to the WAN. This system enables the boiler to heat much less frequently (as often - depends on many factors, power boiler, heat homes, weather, the calorific value of the fuel, etc.).

There is one important point that is worth knowing: for each type of fuel in the boiler will be different power. How then to choose? By the type of fuel that you will be the primary. All the same, after all, some kind of fuel do you think is the best option for heating. And one more thing, which should take into account when choosing: in imported boilers are manufactured for sale in the euro area, the rated power is indicated in the boilers for Russia - the maximum. And this is a considerable difference in performance. Sellers, by the way, give voice to the maximum power, which is also necessary to keep in mind. Therefore, be careful.

Combined boilers for heating homes will have different capacity of each fuel

It is clear that the more different types of fuel, the more expensive and bulkier equipment. Exception - wood boilers and electricity. Their dimensions remain substantially unchanged - the boiler heating element is embedded, which is activated automatic after the firebox is damped and the coolant temperature in the system falls below the critical point. Price combined boilers firewood, electricity or coal-electricity is almost the same as pure wood - minor alterations. Dimensions also unchanged, as just something and you need that to insert small enough to fit the heater. Such a system is useful if you are unable to regularly throw firewood, or do not want to get up at night. The only thing to remember: the electric part produces only a third of the power boiler. That is to heat the house with boiler electricity, do not get a full, but to maintain the system and to prevent the defrost - please.

Similarly combi boiler arranged on carbon and electricity. In this case, generally you can use any solid fuel: it is the furnace-fired boilers is unlikely without consequences can lay the coal as it burns at a much higher temperature than wood, and not just any wood-burning furnace can a bear without consequences. But the coal furnace to load firewood, pellets or peat as possible. Another issue that will have to because of the small volume of the furnace load them often, but the work of a boiler will.

Russian combined heating boilers "Vamos-TT"

An example of the combined boiler coal / electricity - Warmos-TT from the Russian company "Evan." Rather, you can use and wood and coal, but the furnace does not have the largest amount, because it is more convenient to use coal. It boilers Russian manufacture because adapted for combustion of moist wood (to 70%). Pawdite, they give out is not the most high efficiency - 65-75%, but have small dimensions. Thermal insulation of the boiler - combined - heat-insulating materials are combined with a water jacket, is a regulator of traction. Optionally, the regulator rod and heater with thermostat and podderdaniya temperature limiter for the water temperature in the system in the absence of fuel bookmarks. In general, combination boilers wood / coal / electricity is produced mostly Russian companies, well, or import such boilers is not available due to low prices.

Finnish combined heating boilers

A large enough share of the market occupied by the Finnish boilers. This is due to several reasons. Firstly, their climate is similar to ours, so we can expect that their power will be enough and in our conditions. Secondly, most campaigns are working for a long time, and therefore have gained experience, have some potential. Well, and, thirdly, the quality of them is on the level.

Jäspi Group - one of the Finnish companies operating in the sector of heating equipment. Their boilers have a good reputation and are all equipped with heating elements. In the basic configuration the boiler heating element on one - 6kW. Under the order can put 2 or 3 pcs.

Finnish combined heating boilers Jäspi

In line Jäspi VPK can use wood, pellets, diesel fuel, gas. Jäspi Tupla has a high efficiency, the copper coil, running on diesel / gas and solid fuel. In this line the furnace off-line, only the products of combustion are located on one pipe, because the smoke channels are combined before the chimney fitting. Work on gas or diesel fuel characterized by high efficiency. When properly configured, the burner fuel is combusted almost completely, so that the cleaning of the combustion chamber is required only once a year. When using wood depends on their size modification: in Tupla 1 S - 35cm in Tupla 2 S - 50cm.

Some specifications Jäspi Tupla and Triplex

Boilers Jäspi Triplex - model with reduced emission of harmful substances into the atmosphere, equipped with new ceramic grate. It is also possible to use firewood 35 and 50 cm. For modification with 50cm long wood upper combustion can be realized.

In line Jäspi Biotriplex uses the latest development: the transition from pellet to wood and back does not require a change of equipment. The two furnaces are independent of each other.

heating boilers combined gas-solid fuel

One of the most popular combinations of fuel - solid fuel / gas. Many houses are built in a cottage village, where summing up the gas pipeline is planned. Because to buy and install the first solid-fuel equipment, and then, after a few more years and gas - not the most sensible solution. So people are looking for boilers that can simultaneously work on solid fuel and gas. In addition to the above Finnish boilers, there is a proposal - Polish combi boilers Zota heating. They can use a solid, gaseous (natural gas or LPG) or liquid fuels, but they belong to the class of removable boiler, i.e. to change the fuel required to deliver / remove the burner. If you are not going to frequently move from one energy source to another, this equipment - a good choice, because the price for it is low.

Combined heating boilers Zota

For those who frequently change will fuel more attractive combined dvuhtopochnye boilers ECO CK Plus. Here the scheme of work is different. If used as a primary solid fuel, after the termination of combustion and reduce the temperature of the coolant below a predetermined, automatically activated the other burner in the furnace. And it works with gas or liquid, which is set in the settings. In the cell for solid fuels can also be set pellet or oil burner. There is a variant with and without hot water. Very interesting and truly multivariate boiler. Of course, there are also disadvantages: the price and size.

Combined gas heating boilers + pellets

Cast iron combined DAKON FB boiler can work with pellets

Czech combined DAKON FB boiler is a solid fuel pellet and may be equipped on the burner gas and diesel fuel. When using solid fuel electricity required - this part of the non-volatile hardware. A great option for heating in those areas, where often there are power outages. However, the pellets in the boiler is burned DAKON FB not using special burners and flame as ordinary wood. Because it is not a pure pellet boiler, but rather the wood, which can run on pellets. Regarding gas - installing the burner and turn the gas boiler operates. Heating water for heating system takes place in a water jacket, hot water preparation is not provided.

Generally, to change the fuel pellets / gas burner requires replacement. Easily switch can not do here. These boilers are called shifts. But you can find a combination of multi-fuel boiler, where it is possible to use pellets and gas. For example, Finnish Jäspi VPK boiler may work with pellets, gas / diesel oil, wood, charcoal, electric heaters and guest.

There is a very interesting version of the Austrian combi boiler Wirbel Eko CK Pellet Plus. It has two furnaces. One works with pellets, the second - on solid or liquid fuel, gas - to choose from. Capacity of these boilers - 25, 35, 50 kW. Components - pellet burner, a screw hopper 330 liters, the control automatics, the door for mounting the burner.

Russian combined heating boilers

Present in the market and Russian producers. Combination "FAX" boilers working with wood and coal, is to maintain the heater temperature of the coolant. Power - from 20kW to 100kW, there is modification, equipped with a stove for cooking. There may be one-circuit or dual-circuit may be equipped with a gas burner. In the base there is a thermometer, the coolant temperature sensor. Water heated water jacket and an optimized coil, located in the upper part of the furnace. The price of such boilers of Russian production of 24 thousand. Rub.

Another Russian combined boiler - "Smoke". The principle is simple: the main source - wood or coal. When a burn-out temperature is lowered and the fuel is switched electrical part. The boiler body - bent from a single sheet with a minimum number of welds. The furnace - one door - two: one boot and one ash-pit. At the request of the customer established a three-stage heater for 3 or 6 kW. Three stage - which means: one heater can operate in three modes 1/2/3 kW or 2/4/6 kW. Power is regulated by an automatic, if any, or manual switching using controller.

Boilers combined Russian-made "Smokey." Specifications and photos

Combined "Kupper OK" boiler from the Russian "Teplodar" - multifuel planimetric. Works with solid fuel (wood / charcoal / briquettes) and liquid / gas, there is an electric block. Available capacity boilers 15, 20, 30 and 45kW. Is a modification of the hob. This multi-fuel boiler, but it works in a shift operation - simultaneous operation of two or more types of fuel is not possible to change the type of fuel required equipment replacement. On the positive side it can be noted that the price compared to any import boilers several times lower.

Russian combined heating boilers

It can be noted from the boiler features: smoke box located in front of the loading door, which makes it possible to clean it while the boiler or change / control the position of the damper, which regulates cravings. Quite heavy fuel loading chamber allows to lay as large oversized logs to 50cm, and the coal bucket or shovel (maximum - 2 buckets). Torch gas or pellet does not require plumbing work. Heating elements are included after the burning fuel and the cooling of the coolant to the threshold value.

The use of multi-fuel boiler of the combined type for heating private houses

Combined heating boiler - a modern device using not only various types of solid fuel for heating the coolant, but also diesel fuel, gas, electricity, etc. To date, such designs are the simplest and, at the same time, economical means for creating standalone.. heating the house. However, you need to know a number of nuances, which will be mentioned in this article for the proper selection and operation of such equipment.

Features boilers combined type

Externally combi boilers differ from conventional units if only for its size

In the context of Russian cold winters matter of choice of heating equipment is becoming ever more urgent. Naturally, one of the most obvious way out is to connect to the district heating network. But this is only possible in the city. For a country home as the best option would be the heating system using a combination-type boiler, which is able to be used in several types of fuel. This device allows you to quickly jump to a different type of fuel, which ensures the heat in the house, even in the event of disruptions in the supply of an energy or raw materials zavozke.

Depending on what type of energy is present in a specific area, low-rise construction project may involve the following types of combined heating equipment:

Important! There are heating boilers, combined, are subject to the appropriate conversion can work on four types of fuel. However, the presence of additional equipment by means of which an easy transition to another boiler fuel, slightly increases its cost.

The video presents the recommendations on the choice of multi-boiler of the combined type.

For successful use units that operate on diesel and gas, it is necessary to produce a constant shift of the burner. There are universal models that differ very high cost. If we talk about the boiler with wood and electricity, the heating elements of its design are present along with the combustion chamber. The solid fuel fired boilers, involving the possibility of the transition to gas appliances, the gas burner is also used.

Important! The process of changing the fuel can take place both in manual or automatic modes. The first option is simpler and cheaper device automatic counterpart.

Driving unit, working on four fuels

The most popular are solid and electric composite structures. To explain it simply: at least one type of solid fuel, whether wood, wood chips or pellets, is present in every region of Russia. The availability of electricity is one of the basic conditions for the creation of a modern comfortable accommodation.

Such combined heating boilers comprise a furnace, which is used for burning solid fuel, and a heat exchanger disposed above it. That it happens coolant heating. To ensure the operation of the boiler from the power supply to the heat exchanger installed special heating elements, the heating is regulated by the control panel.

Important! The majority of the combined type boilers using solid fuel and electricity, is equipped with automatic, allowing to include heating elements with a deficiency of heat generated by the combustion of firewood. Equipment of this type is very easily connected to the "home" system and able to maintain a minimum temperature in the automatic mode in the absence of occupants. Thus, by the time of arrival to the owners house, comfortable for living temperature is reached in his room.

The device Boilers running on liquid and solid fuels

most often used combi boiler, not only to heat the heat transfer medium, but also to provide hot water. It is about two-circuit units, which are not only able to maintain a comfortable temperature in the housing, but also responsible for the supply of hot water. One circuit in such equipment is responsible for heating the coolant, and the other preheats the hot water.

Tip! Combi boilers are highly efficient only when used in winter. In the summer, to produce hot water to heat the entire boiler have, moreover, that the first circuit remains untapped.

Now let us consider in more detail some of the most popular types of such equipment:

  • Solid-electric. Such units can be operated at a voltage in the network 220 and 380, producing power in the range 3.5-9 kW. Some models allow you to change phase, using equipment to operate in networks with different voltage. Great for weekend homes because space heating can be performed using firewood, and time of departure; automatic heating which supports indoor positive temperature.
  • Solid fuel-gas. In such units equipment is minimal, but because they require constant attention. The popularity of this type of boilers contributes to their cheapness.

The differences in the unit diesel and solid fuel boilers

  • Gas DMU. The transition between fuels is very simple: it is enough just to replace the burner, without making any complicated settings.

Important! Many users of autonomous heating systems are of the opinion that the construction of the "dizel9mdash; gaz9raquo; They are unprofitable. The fact that a gas has a considerably lower cost, and it is most expedient to use this unit to operate solely on gas. But even in this case, the ability to work on a diesel engine can be used for hedging, if for some reason the gas supply is cut off.

  • Gas-dizel9mdash; elektrichestvo9mdash; solid fuel. This is the most versatile heating unit, which is simply indispensable in areas where you may experience interruptions in the receipt of gas or electricity. Such boilers can be universal both initially and during the operation refurbished by installing additional components.

Consider the basic pros and cons of this equipment, because they are crucial when choosing a particular model of boiler. The advantages of this type of equipment are as follows:

  • The fuel used for these constructions, is available and has a low cost. At least, there is the possibility to freely move to a more favorable fuel without changing for this heating unit.

Multi-fuel boiler connected to the heating system.

  • Depending on the weather conditions it is possible to control the boiler operation, and this in turn reduces fuel costs.
  • Since such constructions allow to use two or more kinds of fuel, it is the guarantee system availability if one of the types of raw materials is offline.
  • The best option for automatic operation in a "smart home" system.
  • Reliability and ease of operation and durability.
  • Environmental cleanliness of equipment.

However, the combined boiler heating private house has its drawbacks:

  • For the installation of such equipment in the house a special room must be provided. It also stored fuel reserves.
  • To connect the equipment requires three-phase network. Most likely, during the installation of the boiler need to be agreed with the power company.
  • Scope of these units is very limited due to the fact that such heating systems may be applied only to individual residential construction.
  • With regular operation of such equipment are mandatory regular preventive check-ups and maintenance.

Solid fuel boiler with burner pluggable

Important! Despite all of the above disadvantages, the merits of this equipment much more. You should also take into account the excellent operational performance of the combined boilers that contribute to a significant increase in demand for this equipment.

Rules of operation of the combined boilers

When installing and using the boiler of the combined type should take into account a number of nuances:

  • Solid fuel and electric boilers have quite a lot of weight. Therefore, all of them are outdoor, and in need of pouring a solid foundation.
  • When installing the boiler chimney to be mounted with a sufficient cross-section to provide suitable traction.

The boiler to the chimney

  • The chimney must be in the back is insulated mandatory order that would eliminate the risk of fire of those designs that are with her in direct contact.
  • With constant operation of the equipment necessary to periodically clean the ash pan. Cleaning frequency is directly dependent on the degree of fuel combustion, its type, and the intensity with which he will operate the boiler.

Tip! It is desirable to lay the steel sheet, which is dictated by safety regulations to the combustion chamber of the boiler. This coating will provide the necessary protection against the floor of sparks and burning of fuel particles.

In addition to a solid foundation, the boiler requires placing heat-resistant material

There are various raw materials, which can be operated multi-fuel boilers: solid fuel (wood), gas, electricity, liquid fuels. Because of this "vseyadnosti9raquo; This equipment is very popular. We have examined all the features and nuances of such units, which should pay attention when buying. Considering all of the above recommendations, you can choose really reliable and efficient equipment that will create warmth and cosiness in the house more than a decade.
