Combined heating boilers

Combined heating boilers for private homes

Universal heating boilers steel genius invention allows to heat houses a variety of fuels. It can be wood, coal, natural gas, diesel fuel, electricity and the like. Boilers universal private homes are in demand by those who know how to save on heating. They are also useful for those planning to go further from one fuel to another, for example, diesel fuel gas (as soon as the natural gas pipeline will be routed to the home). What are combination boilers?

In this review, we will consider four types of boilers combined fuel:

  • "Gas - diesel" - the most economical and easy-to-handle option;
  • "Gas - solid fuel" - a universal solution for country houses;
  • "Electricity - solid fuel" - the smart choice for heating garden;
  • "Gas - diesel - solid fuel - electricity" - any suitable fuels.

Let us dwell on the boiler data features and find out the conditions in which these versatile devices are used.

Combination boilers "gas - diesel"

The most comfortable and versatile model for home boilers, those that can run on both gas and diesel. Their indisputable advantages:

  • extremely simple construction;
  • minimum sizes;
  • reasonable price.

Universal gas-diesel heating boiler. To switch to another type of fuel is just enough to replace the burner.

Universal boilers "gas - diesel" are performed in small housings within which is located a heat exchanger. Burners in them brought outside, they are separate modules. If you want to go with diesel gas, replacing the burner is sufficient.

Burners for gas and liquid fuels have a similar structure. Their task - to create a flame flow within the heat exchanger. The gas burns in the normal mode, and the liquid fuel is subjected to sputtering to form a flame. Connect the selected burner to the housing installed inside the heat exchanger, we can provide an effective and inexpensive heating private houses. Moreover, the burner under the diesel will have to be bought separately - often it is not standard.

What good combi boilers' gas - diesel "? The first thing to note their simplicity, which provides a minimal amount of damage and settings, and in the second we will highlight both low cost fuels. For example, the operation of electric boilers leads to a truly enormous costs, while gas and diesel oil are quite cheap. Bay full tank of diesel, you can count on it for a long burning. With regard to gas, it can be a trunk or a balloon.

Combined boilers running on gas and diesel fuel, will be an excellent solution for heating of country houses that have not yet connected to the gas line. That is the first time it is possible to heat the diesel fuel at home, and then switch to gas. not the need to change the pot - just install the appropriate burner. As the cost of the burners is low, it does not hit the pockets of what would happen if a complete replacement of the liquid to a gas boiler.

Universal boilers "gas - solid fuel"

Universal boilers' gas - solid fuel "- is the best solution for homes which will soon hold a gas or there are faults with his delivery.

How else can heat the homes that are not connected to the gas pipeline? For this often used combined boilers "gas - solid fuel". These versatile units burn wood, coal, pellets, and many other materials until pressed straw. They also work on the main balloon or gas. For this purpose, in their structures are provided immediately two combustion chambers, the first burned gas in the second burning firewood.

Combustion products are poured into a special tray, which simplifies the maintenance of the equipment.

Combined boilers for solid fuel and gas are different from boilers to gas and diesel sizes. For burning wood, coal or fuel compacts need large combustion chamber, so that such boilers are massive enough. They are made of steel or cast iron, is used outdoor construction. Some models are equipped with devices for automatic feeding of fuel pellets.

To suit combined boilers for gas and solid fuels? They will be useful to all owners of suburban housing, temporarily not connected to the gas line. The boilers provide efficient heating of premises, allowing to choose the type of fuel. If the home is no gas, firewood used for heating, charcoal or any other combustible material available. As soon as the gas will be go directly to it.

In your community there are interruptions in the gas supply? Do you have a source of low-cost solid fuels? Then universal heating boilers "Gas - wood" will become your indispensable solution. At the termination of the gas supply can be loaded into the furnace of the wood, light the fire and enjoy the warmth while the neighbors will freeze. When resuming gas supply will only wait for completion of the combustion.

Combi boilers "electricity - solid fuel"

Heating boilers for solid fuels and electricity, do not allow your fuel system be chilled and the house if there will be nobody to throw firewood.

combi boilers "electricity - solid fuel" is often used for heating of country houses and cottages. They are built on the same principle as boilers, gas-fired and solid fuel. However, they set different power heating elements instead of a gas burner. The largest part of these combined devices is the furnace in which the loading firewood. Sami boilers made of steel or cast iron, the type of installation - floor.

Most often combined boilers "electricity - solid fuel" work it on the wood. This is a relatively cheap fuel, which is sold in the settlements that are not connected to the gas mains. Having bought a truck of firewood, you can ensure yourself warm all winter. Regarding the heaters, they play a supporting role, supporting heat in the absence of firewood.

The system works as follows: the furnace load the required amount of firewood boiler starts to heat the room. As soon as they burn through and the temperature starts to fall, the work turns on heater. It maintains the desired temperature in the heating system, without allowing the coolant to cool down. If a lift to the furnace cleaved (or pellets) and to burn them, heater turns off after a certain time.

Advantages of combined boilers "electricity - wood":

  • opportunity to save on electricity when working with wood;
  • the use of any types of solid fuel;
  • the presence of anti-freeze mode.

Freezing water tends to expand, which can lead to rupture of the heating pipes in winter.

The latter mode will be useful for those who use their vacation home to stay on weekends or holidays. By including Antifreeze, you can safely go into the city, and the boiler will automatically maintain a positive temperature in the system. This reduces the likelihood of rupture of pipes due to freezing coolant. The main thing that in the cold is not lost electricity that happens in small towns and country partnerships.

Universal heating boilers "electricity - solid fuels" will help reduce the cost of space heating. The solid fuel has the lowest cost, and in some cases it is even free of charge. For example, in rural areas can be burned in these boilers, straw and other plant waste. If there is no money to buy firewood, they can be cut in the near woods - here need only labor costs felling.

If the wood is not available, the equipment will work from the mains. But to get involved in this mode of operation is still not worth it - high energy consumption backfire giant figures in electricity bills. Instead of wood, you can use any other solid fuels such as coal, wood pellets, peat briquettes, and more. The main disadvantage of these boilers are their large size.

Universal boilers "gas - diesel - solid fuel - electricity"

Universal omnivorous boilers have not only large in size, but not a small price.

Whether there are boilers that can run on any type of fuel? Yes, this equipment is - This universal boilers' gas - diesel - solid fuel - electricity ". As understood from the name, they can operate by electric power, can burn gas, diesel fuel, heating oil, wood, coal, briquetted fuel, compressed straw and so on. The versatility of the equipment provided by their unusual design.

Universal boilers "gas - diesel - solid fuel - electricity" are made in the floor and by imposing different sizes. The biggest of them - a fireplace for solid fuel tabs. It loaded wood, coal, pellets, briquettes and other solid fuels. Some models are equipped with hoppers and feeders for automatic feeding pellets.

The universal design of boilers are provided heating elements. They ensure operation boiler in the absence of gas, liquid or solid fuel. It should be understood that this heat treatment leads to high energy costs. But in some cases, electricity is the only available source of energy for the operation of the boilers. The most cost-effective modes of operation:

  • of gas;
  • on the wood (especially if they are free);
  • Local (or furnace fuel).

The universal boilers, gas and oil burners are separate units that connect to a specific port.

For work on diesel and universal gas boilers equipped with ports for the connection of external gas and fluid burners. Acquire such burners can be in many specialty stores.

As a result, we get a device capable of giving heat from anything. There are wood? Perfectly! Load them into the furnace and enjoy the warmth. Found the source of low-cost diesel fuel? Buy liquid burner and connect it to the boiler. Note that fluid burners operate automatically, independently igniting the flame and regulating the supply of fuel. If the gas will be in your home, you can buy a gas burner.

But why do we need other kinds of fuel, if there is a gas? Elementary - for gas you have to pay, and in the cold winter expenses received very noticeable. If there is a source of low-cost or free firewood, the heating costs are virtually nil. Therefore, the versatility of these boilers is their main advantage. Now the drawbacks:

  • the high cost of the equipment;
  • the need to purchase additional burners;
  • impressive dimensions of boilers.

Universal boilers' gas - diesel - solid fuel - electricity "used for heating private houses, dachas and many other types of buildings. But before you buy you need to think about the feasibility of such a purchase: if you really need the ability to work on all types of fuel or you can do two? Then, instead of such a complicated machine can be purchased more simple pot "gas - solid fuel", which will cost much cheaper.

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 dvuhtopochnye boilers ECO CK Plus

For those who are attracted by the combination of the gas / solid fuel / electricity suitable Jäspi Triplex Finnish and Swedish CTC described above. Provided in this campaign CTC 2200 TRIO boiler, which can work on all types of fuel - diesel oil / gas, wood, coal, electricity. Of combined boilers CTC launches CTC has 1200 Family 40, which can be used in gas / diesel and electricity, and several options for using gas and diesel fuel. Thus suitable as a solid fuel and briquetted (specify when purchasing regarding each modification).

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.
