The most reliable outdoor gas boiler. The most attractive for the price. Types of combustion chambers: open or closed?

Determine which is the best gas boiler for the house and give a clear answer to such a question is impossible. Too many factors affect the choice of the optimal boiler for a particular housing. It is clear the owner's desire to buy a boiler that would work long and reliably, was beautiful, convenient and inexpensive. But we need to clearly understand that the boiler is a complex technical device that will inevitably fail someday.

How the boiler will work, how many problems it will be with it in the process of operation, largely depends on the manufacturer. But even the extra-class heaters, regardless of the brand of gas boilers, in case of breakdown need to be repaired. Therefore, it is necessary to select the heating boiler, which is better and closer to the service. After all, the lack of service can lead to unpredictable consequences, especially in the winter. Therefore, the availability of service is one of the most important criteria for choosing a heating boiler.

Variety of boilers for choosing the best in the world

Before answering the question - how to choose a heating boiler for a particular home, it is not superfluous to get acquainted with the types of modern gas heating boilers. There are many tips for choosing boilers, but the main advice is the selection of the boiler in terms of capacity.  After all, its main task is to heat the house and if the power is insufficient, the boiler will work hard in severe frosts without stopping, but the temperature in the room will be low.

Approximately the power is determined - 1 kW per 10 m2.  Usually the value of the received power is increased by 20% or even by 50% depending on the climatic zone. The main types of heating units offered by manufacturers of gas boilers for individual houses are wall and floor, single-circuit and double-circuit, chimney, with a coaxial chimney and turbocharged with separate input / output.

Energy-independent and non-volatile gas boilers

Energy-independent boilers, for example the domestic gas boiler Baltgas, have many advantages, but they need a stable 220-volt electrical network. Of course, many devices have been designed to provide redundancy, of which the most famous are backup generators and IBN (). Non-volatile boilers do not need electricity, but they can work in circuits with natural circulation of the coolant.

Floor and wall heating units

Of course, in the interior of the kitchen is best to fit a hinged gas boiler which one should be better determined only based on specific conditions. To advice on the Internet should be treated with caution, because recommending which gas dual-circuit boiler is better to buy reviews reflect only the author's point of view. It should also be taken into account that the power of wall-mounted gas boilers rarely exceeds 35 kW, so if more power is required, then it should be stopped on the floor.

For reference. Domestic company Gefest produces gas boilers Hephaestus both hinged and floor type with a capacity of up to 40 kW. Boilers are equipped with Italian automation and in quality are not inferior to European models. The reviews found on the network for gas boilers of Hephaestus are extremely different, but FGU Rostest-Moscow conducted tests and the boiler received the Golden Badge of Quality.

Organization of hot water supply

Of great importance is the availability of hot water (hot water). Therefore, the best wall-mounted gas heating boilers are those that are equipped with a built-in boiler, with the possibility of connecting an external storage tank. For example, the gas boiler Wolf - the leader in the class of compact hinged boilers. Several series of wall gas boilers are available with a capacity from 5.6 to 100 kW. Among them, for example the model Wolf CGW with a boiler of 140 liters or model Wolf CGS with built-in boiler with layer-by-layer heating of water. On such a wall gas heating boiler the price starts from 1000 euros.

When choosing a gas boiler, you need to focus on the performance of DHW, because a gas boiler with a water heater of flow type has a low productivity and hot water may simply not be enough to fully meet the needs. If you look for the answer to the question: which dual-circuit gas boiler is better for hot water, then you need to choose one that has a non-running water heater, and an integrated boiler.

Features of combustion chambers of heating boilers

Gas boilers have two types of combustion chambers - an "open combustion chamber" (atmospheric) and a "closed combustion chamber" (turbo). More detailed information about combustion chambers can be studied in our article

Open combustion chambers

An open combustion chamber requires an influx of fresh air, it is taken from a room that must have good ventilation. For boilers of this type you need a duct chimney. The Borin gas boilers have proved themselves in the market, they are non-volatile, and the power reaches 100 kW.

Closed combustion chambers

In a design with a closed combustion chamber, the air for operating the burner is taken from the street through a coaxial chimney. It represents two pipes of different diameters, one in one. Through one pipe, the combustion products are removed, and through the other there is an influx of fresh air.

Boilers with a closed combustion chamber "turbo" are considered to be the most economical, since the fan creates the best conditions for combustion of gas and removal of combustion products outside.

Moreover, the fan is controlled by the automatic system, which, after receiving signals from the gas analyzer, forms the optimal combustible mixture.

Do the opinions on the Internet influence the choice of a gas boiler?

Determine which gas boiler best buy reviews will help only if they are real, and the conditions for using the boiler are the same. And here it's not so simple. For example, in the reviews write that you should not buy a Chinese heating boiler, because it often breaks, etc. Do not follow the advice, immediately buy a high-tech boiler, for example, the company Wolf, without knowing in advance, say, whether there is in the region Customer Service.

Any technique can refuse, and if a neighbor with a Chinese boiler service is nearby and works fine, then any breakdown is eliminated quickly and promptly. And what should the customer do if there is a breakdown in severe frosts, if there is no service and specialists for repairing a technically complex boiler? Can this happen? Without a doubt, this is a very real situation, so you need to provide the worst case scenario.

Do I need a heating reservation?

In order not to freeze your house you just need to make a reservation. Variants can be different - installation of electric boilers, boilers on solid or liquid fuel, etc. As an option, it is possible to propose for the reservation of heating Thermor convector instruction which specifies the rules of installation and use. The convector is installed on the wall and has a power of 2.5 kW. Equipped with a convector and reliable automatic for safety.

Review of popular gas boilers

A new line of heating units manufactured by JSC ZhMZ, which is sold under the trademark ZHUK, has been on sale. Particularly popular is the double-circuit gas boiler Beetle, floor, chimney. Automation, installed in boilers, Italian production. The boiler can be used for private houses up to 3 floors. Zhukovsky gas heating boiler whose price is much lower than that of European models of the same class, is used for heating up to 400 m2.

Sime gas boiler

In the market there were gas boilers of the famous Italian company Fonderie SIME S.p.A. Compact wall gas boilers Sime have unique technical capabilities - automatic ignition, flame detection and the ability to control the contour of the solar panels, which are connected to the DHW circuit. SIME company produces not only wall-mounted gas boilers, but also outdoor gas and solid fuel heaters. Boilers of this company have all international certificates and are high-tech heating equipment.

Two-circuit gas boilers Arderia

Under the license of Daewoo company, South Korean company Daesung produces high-quality heating equipment. Use the gas boiler Arderia instruction recommends for individual houses or apartments with an area of ​​up to 300 m2. The design of all models of Arderia boilers is carefully thought out, and a wide service network contributes to the popularity of Daesung gas boilers. The structure of the structure includes nodes of Japanese, Danish and German production and this circumstance is reflected in the instructions for the gas boiler Arderia.

What is the best boiler in the world?

Believe me, no one can answer this question clearly and unequivocally. Perhaps, it is possible to answer only so - such a boiler should be the best way to approach the region, home and to the operating conditions. In addition, the service should be decent and affordable. And most importantly, do not forget about reserving the heating system. Reservations need to be carefully thought out in advance and choose that way and then the reserve fuel that is available in the region. It can be combined with TEN, which will provide double redundancy, or an electric boiler connected in parallel with the gas unit.

The optimum choice of the heater for a private house is outdoor. It is capable of heating a room of up to 600 square meters.

The only disadvantage in comparison with the wall () - floor unit is a separate room for installation (). But in terms of price / power ratio, floor models benefit from wall-mounted models.

What are the floor gas for heating a private house, how to choose?

According to the material of manufacture, a cast-iron boiler is preferable. It has a higher wear resistance and corrosion resistance than steel, more inertia.

The steel boiler serves an average of 15 years, cast iron - half a century. Steel is preferred for wall mounting. its mass is less. For the floor unit mass of the role does not play.

Floor heating gas boilers - which is better in terms of design and performance? The main criteria are power, economy, reliability, convenience in operation, cost.

Constructively the boilers are different:

• by the number of circuits;
• by type of burner and chimney;
• by type of heat exchanger;
• by type of automation.

Power selection

Power depends on the area of ​​the house. Usually the figure is 1 kilowatt per 10 square meters plus the correction factor for the region. For the two-circuit models, add another 25% ().

The economics and reliability of the boiler depend on the features of power regulation. The adjustment can be two-or one-step.

There is also a third, most economical option - a modulating burner. Provides a smooth adjustment and minimizes fuel consumption.

Choice of burner and type of combustion chamber

The burner can be atmospheric or ventilator (). In the first case, the furnace is open, oxygen for combustion comes from the room, and smoke leaves through the ceiling along a standard chimney.

Ventilator burners are equipped with closed-type boilers: air is injected by the built-in fan through a coaxial pipe from the street, along the same pipe combustion products are diverted.

Fan burners not only work more efficiently, but are more resistant to pressure drops in the gas main.

By type of inclusion distinguish burners piezo and with electric ignition. In the first case, the igniter during the operation of the boiler burns constantly, in the second it works when the fuel is supplied to the burner.

The second burners are more economical, but they need electricity. Hence, you need a surge protector or a stabilizer to protect against voltage drops and interference.

Automation

The automatic control system of the boiler can be volatile (powered by electricity) and mechanical ().

Advantages of the first type:  simplicity of management, fuel economy, a lot of useful functions (self-diagnosis, display of user information on the display, etc.).

Minuses  - higher price, there is dependence on the electricity network. Those. additional costs for electricity and susceptibility to damage due to voltage surges. It is advisable to purchase protective electrical equipment.

The energy-independent system is structurally simpler, does not depend on electricity, is well repairable, cheaper.

Cons: requires user control, less economical gas consumption, less functionality.

One or two circuits

The first option is designed only for heating, the second one also supplies hot water for household and household needs (). A compromise option is to purchase a single-circuit boiler and connect an additional boiler to it.

The advantage of a dual-circuit boiler is its compactness (). But for maintenance it is much more demanding than single-circuit, less economical and not very convenient in a large house if the boiler and DHW service points are spaced a long distance. Moreover, in this case the additional pump will not be installed.

Minus one-circuit with an additional boiler - a large loss of space. It is possible to equip the system with an additional pump, but the water consumption will still be limited by the size of the boiler capacity.

The boiler and boiler will cost separately more than a two-circuit unit.

The heat exchanger of the double-circuit boiler can be separate and bithermal. The first option is considered more reliable, durable and functional.

Convection or condensation

Another significant parameter for selecting a floor gas boiler is the heat transfer method. The condensing boiler is equipped with a heat exchanger of a complex spiral shape, passing through which the coolant is partially cooled.

Condensation settles on the walls. Condensation comes with the release of heat. Those. If the conventional (convection) unit uses only the energy of combustion of the fuel, the condensation unit will separately produce heat upon condensation.

The efficiency of these boilers is the highest, 98%. But they have certain operational limitations: the coolant enters the system partly cooled down. For warm floors it is good, for radiators - it's bad.

Manufacturers

Today on the Russian market the most popular boilers are the following brands:

• BAXI (Italy). Series SLIM (open firebox), Galaxy (closed). One and two circuits. Power from 22 kilowatts, efficiency is not less than 90%, the price is from 35 thousand rubles;
• Protherm (Slovakia). Series Bear. One and two circuits. Power from 15 kW, efficiency from 90, cost from 25 thousand;
• Buderus (Germany), the Logano series. The main and liquefied gas, one and two circuits. Power from 20 to 300 kW, efficiency from 93. Low noise. Cost from 60 to 600 thousand;
• Vaillant (Germany). The VK INT series (open furnace), ecoVIT and ecoCOMPACT (condensing models). Power from 16 to 160 kW, the efficiency is not less than 94. The price is from 50 thousand.

From German manufacturers, Bosch, Wolf and Viessmann also receive good reviews, and Ferroli from Italy. All these brands have a well-developed service network in the Russian Federation, and also have high fault tolerance.

Budget brands of floor boilers from Russian manufacturers:

• Rostovgazoapparat - the oldest plant of boiler equipment in Russia. Boilers with one and two circuits, steel and cast-iron heat exchangers, automatic HoneyWell, EuroSit. Power from 11 kW, the cost of 13 thousand;
• Lemax and Mimax (Taganrog). One and two circuits, there is the possibility of switching from the main gas to the liquefied gas and back. The boilers are partly equipped with Sit accessories. Capacity from 12, the price from 10 thousand;

• Borin (Lipetsk). 30 models of outdoor units, automatic HoneyWell, EuroSit. Capacity from 11, the price from 20 thousand.

Video on how to choose a gas boiler.

Choosing a gas boiler for heating a private house, we are faced with a huge selection of equipment. The choice of buyers are single-circuit and two-circuit models, wall and floor, atmospheric and turbocharged, simple and multifunctional. How to understand all this diversity and make a really right choice - our detailed review will tell.

In this article we will tell:

• On the main types of boilers for heating private houses;
• On the merits and demerits of gas equipment;
• On the features of these or other devices.

We will also give information on calculating the required power and give user feedback.

Types of gas boilers

How to choose a gas boiler for heating the house - it is known to every specialist who is engaged in the installation of heating systems. First of all, you need to determine the basic requirements for the equipment. Gas boilers are divided into the following categories:

• Wall and floor;
• Single-circuit and two-circuit;
• With open and closed combustion chambers;
• Convection and condensation.

Also there are volatile and non-volatile modifications. Let's look at the above criteria in more detail.

The choice of gas heating equipment for heating a private house begins with the choice of a location for installation of equipment. Here everything is simple - if there is a place for a separate boiler room, you can confine yourself to a floor model. If there is no space for floor mounting, pay attention to the wall modifications.

Floor boilers are often made on the basis of reliable cast-iron heat exchangers - these models have a solid safety margin, they are unpretentious and do not cause problems in operation, they practically do not flow and can work for many years without failures and breakages. In addition, floor models of gas boilers for private houses are characterized by high power - if you have a large homeownership at your disposal, feel free to choose modern models.

Wall-mounted units differ in their compactness. In their internal arrangement, they resemble the most common flowing water heaters, but instead of flowing tap water they heat the coolant circulating through the heating system of the private house. The power of individual models can be very high, up to several tens of kilowatts.

Single-circuit and two-circuit models

For heating private houses, the simplest gas boilers with one circuit are often used. They are extremely simple device - they contain a burner and one heat exchanger. These units are able to work exclusively in heating systems, they do not know how to prepare hot water. Such boilers are made in two versions - in the floor and wall version.

Two-circuit modifications combine at once two units - a flow-through gas water heater and a boiler. Priority is given to the DHW circuit, during its operation the heating is switched off. The design of double-circuit boilers is complex, there are three-way valves, as well as combined or separate heat exchangers. But they are more functional and easy to install and operate.

The main advantage of dual-circuit gas boilers used for heating and hot water preparation is their compactness - they take up less space than separate equipment.

We have one more division of gas boilers - they are divided into modifications with open and closed combustion chambers. Models with open combustion chambers are often called "atmospheric", since air to the burners comes by gravity, climbing straight from the room in which the equipment is installed. As for combustion products, they are removed through a conventional chimney with natural draft.

The main advantages of "atmospheric" models - a simpler design, low noise level, energy independence (typical for certain models not connected to the mains).

Turbated gas boilers for home heating are models with closed combustion chambers. The air for their work is taken from outside the buildings, through a special two-layer chimney. Through the same chimney is carried out smoke removal. Over the combustion chambers are installed fans, which are responsible for the removal of smoke and air intake. Boilers with closed combustion chambers can be installed in any premises of private houses.

Disadvantages of turbocharged models - reduced reliability due to more complex design, noise and increased power consumption (only one fan consumes about 100 watts).

Convection and condensation

Gas boilers for heating a private house are most often constructed according to a convection scheme. It's simple:

• The burner generates heat energy;
• The heat exchanger takes the received heat;
• Heat is sent to the heating system, and its remains - to the atmosphere.

As a rule, the efficiency of such boilers varies in the range of 90-93%. Consequently, up to 10% (and sometimes more) of thermal energy simply fly into the atmosphere.
  Condensing gas boilers are built according to a slightly different scheme - here almost all of the generated heat is taken to the heating systems. As a result of the work, condensate is sent to the drainage. Developers argue that the efficiency of such units is more than 100%, but we know that it is impossible to get more than invested. Therefore, the highest figures are a classic marketing move.

According to data from manufacturers, condensing boilers can save up to 10-15% of gas fuel, when compared with conventional convection models. In practice, these figures may be lower.

Advantages and disadvantages of gas boilers

One of the most important advantages of gas heating is its price, and if there is a gas pipeline near your house, it is pointless to think about other types of fuel.

The use of AGVs and gas boilers for a private home for heating purposes provides certain benefits. To begin with, it should be noted the cheapness of natural gas - it is cheap, and its burning releases a huge amount of energy. The operation of electric boilers is more expensive, and liquid and solid-fuel models are not particularly comfortable. Other advantages of gas boilers:

• Completely automated operation - heating on gas equipment practically does not require user intervention and operates in an automatic mode (unless it is necessary to adjust the temperature);
• Low fuel costs - with this can be compared except that free firewood from a nearby forest;
• Ready to work at any time of the day or night - just activate the heating on the control panel. The same solid fuel boilers will require preparation for ignition and subsequent cleaning;
• Minimal maintenance - as a rule, it is held once a year. But with the liquid and wood-fired boilers, there is much more to do;
• Electric safety - many models of gas boilers for heating private houses can work without access to the power grid.

There were some shortcomings:

The gas is very explosive, so do not neglect the rules for the operation of gas equipment.

• The difficulty in connecting to the gas network - for the launch of the equipment will require authorization documentation;
• Obligatory, though minimal maintenance - do without this will not work;
• The gas is explosive - if there is a gas leak, an explosion may occur;
• The need for separate rooms for some types of boilers - for example, outlets with open combustion chambers require separate boiler rooms.

Nevertheless, gas boilers have been and remain an inexpensive solution for heating in private residential buildings.

The undeniable advantage of gas boilers is their convenience in operation. And if the gas main is not connected to a private house, then the output is simple - we use the connection of balloon gas. True, its quality does not always correspond to the standards - because of this, the burners, heat exchangers and chimneys quickly get dirty.

Types of heat exchangers

Boilers with copper heat exchangers have proven themselves in the market of heating equipment.

If you want to buy a gas boiler for heating a private house, pay attention to the differences in the heat exchangers used. They can be copper, steel, bimetallic and cast iron. Copper heat exchangers are made of refined copper and have good performance characteristics. They easily withstand thermal overloads, they rarely generate leaks, they are characterized by high heat capacity.

One of the main advantages of copper heat exchangers is compliance to repair - in case of detection of leaks, they can be soldered with the most common high power soldering iron.

Steel and bimetallic heat exchangers can not be called the most reliable and practical solution. They tend to quickly burn out, and their internal space is quickly clogged with slag. Therefore, they are not repaired, but most often they are changed. As a rule, steel and bimetallic heat exchangers are installed in the cheapest gas boilers used for heating private houses.

Cast iron heat exchangers are the most reliable and durable. They quickly warm up and cool slowly, tolerate thermal overloads well, and are resistant to corrosion. Cast iron is the ideal material for these purposes, but caution is necessary when installing the equipment, since the alloy is somewhat brittle.

Cast iron heat exchangers are used in floor gas boilers for heating private houses. The technology built on their basis can have very high power (up to hundreds of kilowatts).

As for double-circuit gas boilers, they are of two types:

• With dual heat exchangers;
• With separate heat exchangers.

The dual design is good for its cheapness. In such boilers one heat exchanger, it is responsible not only for heating, but also for the operation of the DHW circuit. But this scheme has a drawback - low reliability. In addition, the dual heat exchanger is often clogged with scum, losing its efficiency. Therefore, such exchangers are equipped only with the cheapest boilers.

Gas boilers with separate heat exchangers have a more complicated scheme - here heat generation is carried out in the main heat exchanger (steel or copper), and hot water is prepared in a separate plate exchanger. In this case, the secondary exchanger does not come into contact with the flame of the burner, it generally is located elsewhere - the heating is carried out at the expense of a part of the coolant.

Design features

We have already said that gas boilers for heating private houses can be single-circuit and double-circuit, convection and condensation, wall and floor, atmospheric and turbocharged. But there are other differences, presented by some design features.

Automation

Gas boilers are equipped with various automation systems. Some of them work on the basis of electronic modules, and others are tied to mechanical control. Both of them have their own advantages and advantages, but one must understand that non-volatile boilers can work in heating systems of private houses without electrification. And if you use balloon gas, you can do without the gas main. Models with electronic control will require access to the mains.

Strapping

Here, two-circuit models benefit, which are already equipped with all the necessary piping: expansion tanks, circulation pumps and safety systems. If there is no binding, it will have to be bought and mounted separately, and this will take additional space. But external strapping has a plus - it is easier to repair and maintain, since it does not require intervention in the internal structure of the boilers.

Control

Gas boilers for heating private houses are provided with simple control panels. But to gain access to the extended functionality, external control modules are used - these are simple room thermostats, multifunction control panels, and remote control modules with connection via GSM-channel or via the Internet.

Other options

Heating equipment is continuously being improved, new and new functions appear in it. The prices for gas boilers for heating a private house depend directly on the functionality given by the developers. And the more options, the higher the price. For example, units with electronic ignition are more expensive than with piezoelectric ones. Approximate prices:

• Simple floor-standing single-circuit models 10 kW - 8-12 thousand rubles;
• Low-power two-circuit wall patterns - from 17 thousand rubles;
• Two-circuit medium power, 20-22 kW - from 26 thousand rubles;
• Two-circuit floor energy-independent, 20 kW - from 15-19 thousand rubles.

A separate influence on the price is provided by additional options and equipment used in the equipment.

Calculation of boiler power

Choosing a gas boiler for a private house, you should pay attention to the power of the equipment. It is generally believed that for heating 10 square meters. m. of living space in the Russian climate requires 1 kW of thermal energy. In the northern and far eastern regions, it rises to 1.2-1.5 kW, while in the south it drops from 0.8 kW.  But even in the south it is accepted to adhere to the average indicator, in case of a cold winter.

Following the formula, we get that for heating a private house with an area of ​​200 square meters. We need a gas boiler with a capacity of 20 kW. But we forgot about the necessary stock - it is needed in case of the presence of heat losses and excessively cold winters. As a rule, the reserve is 10-20%. Proceeding from this, the recommended capacity of equipment for heating private houses of 200 square meters. m is 24 kW.

Table calculating the power of a gas heating boiler for a private house.

The thermal losses are affected by:

• Construction of windows;
• Availability of attic insulation (or heated second floor);
• Presence of insulated walls;
• The ratio of the area of ​​windows to the floor area;
• The number of external walls in a particular room.

Also, the average temperature in the coldest period in the area is taken into account.

The heating circuit is a complex structure from the pipeline and radiators, as well as the boiler, which is the basic element of the system. The correct choice of a boiler for heating a private house will allow for efficient and uninterrupted operation of the heating circuit and will help the system to operate at the peak of its performance.

When deciding which boiler is best for a private house, it is worth paying attention to a number of nuances that characterize the productivity, economy, autonomy and environmental friendliness of the device. The heating system will operate at the peak of its performance, if the boiler is competently selected for capacity. When calculating this indicator, climatic features of the region, the volume of the heated room, its specificity and the quality of thermal insulation are taken into account.

Precisely calculate the heat capacity by force of heat engineers - specialists who will competently evaluate the existing conditions and make a number of necessary calculations. Calculations received by heat engineers will be used in the future to assess the compliance of the selected boiler with the thermal needs of the heating circuit.

Classification of boilers

Any construction shop can offer consumers a huge range of boilers that differ in functionality, price, appearance and principle of operation. Since there are no two identical buildings with identical needs in heating technology, the selection of the boiler must be made on an individual basis. In this case, first of all, the consumer should pay attention not to the design of the boiler and the amount indicated on the price tag, but to the type of fuel used by the device.

The following types of boilers are distinguished:

• solid fuel;
• liquid fuel;
• electric;
• gas;
• combined.

It is generally believed that the most rational option is to select a conventional gas boiler, such as, for example, a gas boiler Buderus Logamax U072 24K reviews about which indicate the purchase of this device. However, not everything is so clear, because each device has its own specific operation and can be adapted to the specific heating system. To understand the differences and similarities of different boilers intended for private properties, it is necessary to study the specifics of their work.

Gas boilers - a combination of efficiency and economy

To heat private property, the owner can buy a boiler for heating, running on liquefied or natural gas. There are autonomous and volatile boilers.

Stand-alone boilers

So, stand-alone models of boilers are not equipped with automation and integrated circulation system of the coolant. They can operate in a completely independent mode and do not require the presence of any energy resources other than gas. An autonomous floor gas boiler with a cast-iron heat exchanger can be installed in a private house, but the owner does not need to install a diesel generator to maintain the boiler's operation in the event of an emergency switch-off of light.

Energy-independent boilers

Volatile devices, such as the gas boiler Kebur, are equipped with sophisticated automatic systems - integrated, electric thermostat, remote control panel, programmable timer, carbon monoxide detector and emergency shutdown system. During periods of power outages, such boilers completely lose their functionality. Therefore, choosing the energy-dependent types of heating boilers for a private house, the owner should consider alternative sources of power for the device, which will prevent the system from unfreezing in winter when the electricity is cut off.

Classification of gas boilers by the method of installation and the number of circuits

Depending on the method of installation, a gas heating boiler for a private home, which can be read on the manufacturer's website, can be mounted and floor-mounted. Floor boilers require a simple installation procedure, and provide for installation in a separate room with a good ventilation system.

For the optimum operation of the floor boiler, the owner will have to install an additional water pump in the circuit and equip the ducts for the chimney with good draft.

The differences can be in the design of the gas boiler itself. Single-circuit devices designed exclusively for heating, as well as two- and three-circuit boilers, which involve connection to a hot water supply system or a warm floor, are singled out. Boilers with different number of heating circuits differ not only in functionality but also in cost, so it is important to choose a boiler that will best complement the designed heating system and satisfy the buyer at a price.

Gas boilers for private house heating prices for which you can find on the manufacturers' websites have a number of advantages:

• economy;
• simplicity of operation;
• reliability.

The following factors can be attributed to the minuses of the equipment:

Solid fuel models

In heating systems, solid fuel boilers have been used for a long time. This is due to the availability of fuel, such as peat, wood briquettes, granulated sawdust, woodworking industry waste, etc. Many modern brands have introduced solid fuel boilers for private house heating in the market to choose the right boiler model, the owner will be able to find out after acquaintance with their characteristics.

At present, boilers are classified according to several criteria:

Also, boilers are classified according to the type of fuel used. Separate solid fuel heating boilers for pellets for a private house, boilers using coal, as well as universal models designed to burn various types of solid fuel.

Specific design of solid fuel boilers

The main feature that distinguishes solid fuel boilers heating universal for a private house prices for which start from 200 cu is their floor format. Such boilers have massive dimensions and a large mass, so manufacturers recommend that they be mounted on a strong horizontal base of concrete or stone.

The specificity of the design assumes the presence of a furnace of a certain volume, which is necessary for laying solid fuel that is burned during the operation of the boiler. As the combustion of solid fuel occurs unevenly, manufacturers install cast-iron heat exchangers of sectional type in boilers that contribute to the smooth, wave-like heating of the coolant.

Advantages and disadvantages of solid fuel boilers

Before deciding to install a solid fuel boiler in a private house, you need to know its pros and cons.

The following indicators include the advantages of the devices:

The disadvantages of the device include:

Boilers operating on fuel oil and diesel fuel (DT)

As an energy carrier, boilers of this type need liquid fuel, which most often acts as fuel.

In private houses, a liquid fuel heating boiler is installed, if the owner does not have the opportunity to use a gas or solid fuel analogue.

The efficiency of this boiler is great, it is characterized by a universal scope of application and with a proper level of insulation can provide heat to a private house of any area. However, when choosing a boiler on fuel oil for a private house, it is worth remembering the safety measures, because the fuel used by the device in the process of work is easily ignited, and violation of the storage conditions of diesel fuel can lead to a fire.

Features of operation of liquid fuel boilers

Mounting liquid fuel boilers universal for heating a private house, the owner must equip a ventilation system of mine type. The best chimney is made of stainless steel, which is adapted to work in harsh conditions. It will ensure the timely withdrawal of condensate and exhaust gases to the street and ensure safe operation of the boiler.

Advantages and disadvantages of liquid fuel boilers

Often, manufacturers offer liquid fuel boilers that, when replacing only one part - the burner, can use natural gas as fuel. This versatility is an additional advantage to the following positive characteristics of the boiler:

1. high efficiency;
