Gas is much cheaper than other energy sources. But with inefficient consumption, a lot of money will be spent on heating for nothing.

Manufacturers are doing everything possible to reduce natural energy losses during the operation of the boiler. What economical heating for a private house, how can savings be made?

The main characteristic of fuel is its calorific value. It is expressed as the amount of heat released per unit of fuel burned.

Today, the optimal calorific value is defined as 8 thousand kilocalories (or 33.5 thousand joules) per cubic meter minimum. The most economical gas ones are those in which the energy of combustion is almost completely spent on heating, and the losses are negligible.

Two chemical elements are involved in the combustion process: the gas itself and oxygen from the air. When heated, these substances begin to interact. The reaction products are carbon dioxide and water.

The energy that is released in this case goes away:

• for heating the coolant;
• into the chimney together with the products of combustion;
• for the evaporation of the escaping water.

The design of economical gas boilers allows minimizing the second and third components. The standard indicator of the efficiency of the unit varies between 90-98 percent. The lowest efficiency is for simple convection models with an open firebox, the highest is for condensing boilers ().

In figures, this is expressed as follows: at the boiler, which can be considered as a source of heating, the temperature of the outgoing smoke does not exceed 150 degrees. In the condensation model, this figure is within 70 degrees, the maximum efficiency is 98%.

If the figure is more than 200 ° C, this boiler is not worth buying. Similarly with water vapor: in a simple model with smoke, about 6 percent of steam is lost, in a condensing one - 0.5%.

Sometimes advertising brochures indicate the figure of 110 percent, but this is nothing more than a marketing ploy designed for an inattentive buyer. Efficiency above 100 can not be in principle. 100 is ideal: it is assumed that the boiler operates without losses at all, which is technically unattainable.

Device Features

The working units of the boiler are a burner (), a heat exchanger, a chimney. The burner heats the water in the heat exchanger, the gases are discharged to the street. Air intake can be natural (directly from the room, in the case of an open firebox) or forced (through a coaxial tube from the street, blown by a built-in fan).

The process is to some extent regulated by automation (). Efficiency depends partly on the adjustment, partly on the design of the nodes themselves.

For a simple burner with piezo ignition, the power is regulated in steps, one or two options. Modulating electronic allows the same to perform smoothly. In a simple igniter, it burns constantly, only the gas supply is regulated. The electronic igniter fires as needed.

The condensing boiler has a cylindrical stainless steel burner placed inside the heat exchanger. The heat exchanger is made as a coil with closely spaced coils.

As it travels through the spiral, the steam condenses on the surface of the water chamber. The process proceeds with the release of heat. The conventional model has a simple-shaped heat exchanger, the process is carried out quickly, the steam does not have time to condense and flies into the chimney.

That is, when choosing a model, you need to pay attention to the following things:

• type of furnace - open, closed;
• Efficiency specified in the description of the model;
• outlet gas temperature depending on the operating mode of the boiler;
• the shape of the heat exchanger: the more complex the geometry, the more steam will condense during combustion;
• the quality of thermal insulation and the thickness of the heat insulator layer of the water jacket. The purpose is to reduce heat loss.

Another criterion is the price of the unit. Condensing models are significantly more expensive. You can buy a simple non-volatile boiler and install a water economizer on the chimney - an autonomous device that will heat the coolant in the return.

It is desirable that the model can work both on the main and on liquefied gas. Tapping into the highway is not possible everywhere, but this is the cheapest and easiest option to manage.

When buying a condensation model, you need to consider that it is optimal for working with low initial temperatures and a slight delta between supply and return (on the return - within 40 degrees).

Wall or floor

The wall-mounted boiler is more compact, it can be hung in any room.

The floor has more dimensions, power, a separate room is required for the boiler room. Consider what is more profitable in your case.

floor boiler

They are usually installed in houses with an area of ​​200 square meters. Most of the models are single-circuit with an open firebox and simple automation. Due to the simplicity of the device, it is easy to choose a boiler with a budget cost.

The disadvantages include large dimensions and weight. The boiler room must be well ventilated, the boiler requires a well-designed chimney: it provides efficient removal of combustion products and draft inside the chamber.

For installation, it is desirable to involve professionals. Be sure to arrange a platform under the boiler made of non-combustible material and a sufficient distance from walls and other flammable surfaces.

Another feature of the floor model is that it cannot work at low pressure, because. the intensity of the burner flame is reduced. And in severe frost, the pressure in the line usually decreases.

Wall

It is hung on the wall on special brackets. The surface of the wall section near which the boiler is located is equipped with fireproof material (metal, asbestos).

The dimensions of the boiler are small, the weight is also (within 50 kg). The boiler room is not needed, you can hang it in the kitchen, bathroom, living room. The variety is greater: many models with a closed firebox, condensing, double-circuit.

The complete set of the unit may include all the necessary elements of the system: pump, expansion tank, coaxial chimney, automation. In the presence of a coaxial chimney, the requirements for ventilation of the room are lower than with a simple system with an open firebox and a standard pipe.

A feature of such boilers is more complex automation. It is more difficult to regulate and debug it with your own hands; for repairs, you need to call a professional master.

Wall mounted boilers are divided into flow and boiler. If you need a large amount hot water choose boiler units or attach an additional drive to the column.

Double circuit or single circuit

More convenient, of course, double-circuit: it not only works for heating, but also provides a house hot water. It costs more, and this is not the only negative: the boiler cannot work on and hot water at the same time. When you open a hot faucet, the heating will automatically turn off.

This is not fatal if the house is large and the circuit is long: the system does not have time to cool down while the hot tap is open. Moreover, it is not scary in the summer when the heating is turned off. For small houses that are operated all year round, this feature is critical: while hot water is supplied, the circuit has time to cool down.

Then it takes a lot of additional energy to warm up. In this case, the most economical gas boilers for a private house are single-circuit: fuel is consumed sparingly, the system works without interruption. For hot water needs, it is better to buy a separate heater.

Conclusion

It is also worth mentioning that even when using a non-volatile boiler, you will need electricity: a circulation pump works on it.

Therefore, it is not advisable to save on automation just for the sake of independence from the network. It is worth having an autonomous source of energy on the farm (for example, a generator).

If interruptions in the power supply are short-term, you can limit yourself to purchasing an uninterruptible power supply.

Video how to choose a gas heating boiler.

The key element of the heating system of a private house is the boiler. In many respects, the air temperature in the room, the general costs associated with paying for heating, depend on how high the quality of the device itself, on the efficiency of its work. Wall-mounted boilers have a major advantage over other similar heating equipment: they take up a minimum amount of free space. There are a large number on the market various models wall-mounted units, which differ from each other in a number of parameters:

• Number of circuits: single circuits are designed exclusively for heating, double circuits will also provide the house with hot water;
• The type of combustion chamber is open (needs a natural chimney system) and closed (from it the combustion products are forcibly sent to the coaxial chimney, which is the safest);
• The presence of electrical devices;
• Type of burner: atmospheric or modulating, the power of which the boiler regulates independently.

When developing this rating of the best wall-mounted boilers of the year, we took into account all these features, we also took into account the opinion of customers, the country where the equipment was created and produced. We tried to compile the most understandable and informative rating, so that after studying it, it would be easy and simple for the reader to choose the most suitable heating boiler for his home.

Many owners of private houses and industrial buildings are switching to autonomous heating, using gas as an energy carrier: this is the cheapest and most profitable.
A huge variety of foreign-made boilers of different price ranges is presented on the market, there are also Russian gas heating boilers, the prices of which are more affordable. Let's take a closer look at them and try to understand the proposals of the domestic manufacturer.

The boiler is primarily a functional device, moreover, the acquisition is not cheap. But the most important thing is that with the right choice, it is the boiler that can significantly reduce the costs of its owner, and the number of heating system repairs, the frequency of visits to service centers and the participation of residents in the maintenance of heating equipment depend solely on the right choice.

Will the boiler start at the beginning of the season, will it have to be lit manually and how often, will it provide the greatest possible savings on heating, will the boiler lead to air pollution and the room in which it was installed, will it lose its appearance over time and how long will it last - it all depends on the correct choice of the boiler, suitable for a particular room. Moreover, you can avoid all the above inconveniences without overpaying, but only competently choosing heating equipment.

When choosing a gas boiler, you usually pay attention to the following characteristics:

Boilers are classified according to installation method, functionality and exhaust gas outlet. According to the installation method, boilers are wall-mounted and floor-standing, according to the type of functionality, single- and double-circuit boilers, according to the method of gas removal - with a closed and open combustion chamber.

Floor-standing boilers are in the greatest demand: they allow you to heat a large area, are reliable and have a wide power range - 11–68 kW.

Russian manufacturers have learned to produce floor standing boilers, adapted to our operating conditions and able to compete with imported samples, therefore, by purchasing a floor-standing gas boiler Russian production, you can reduce start-up costs and get a completely reliable and in no way inferior to foreign, heating device.

The storage unit can hold up to two hundred liters of water. Thus, if you buy a Russian-made double-circuit floor-standing gas boiler, two tasks are solved at once - heating and hot water supply. Sometimes it is advisable to purchase a boiler for a single-circuit boiler, then it will work on the principle of a double-circuit one. However, double-circuit boilers much more compact, so it is better suited for rooms with a limited area. But they have a requirement: the flow of incoming water must be under high pressure. In addition, they are not suitable in cases where the bathroom is located at a great distance from the boiler itself.

Closed and open combustion chamber

As for the type of combustion chamber - an open chamber uses the air of the room, and exhausts the exhaust gas through the chimney, a closed one (turbo) contains fans that take in air from the outside and send combustion products there. Open combustion boilers operate on the principle gas burners, heat up themselves, warm up the air around them (hence the lower efficiency), require some distance from flammable objects. Turbo models are considered more economical and safer.

Among domestic models, you can find all the listed types of floor boilers, choosing according to the necessary parameters. The experts believe modern boilers gas floor standing Russian-made, even if they do not have highly competitive technical and operational characteristics, they perform their main functions properly.

Popular Russian manufacturers of heating equipment

Choosing heating equipment affordable price, it is reasonable to proceed from considerations of individual needs, focusing not only on the brand. In general, floor heating reviews are increasingly positive, perhaps this is due to a decrease in purchasing power, or maybe our compatriots have begun to trust local manufacturers more and have given themselves the opportunity to evaluate Russian equipment.

Domestic gas boilers have a number of advantages for the Russian buyer:

• reasonable price;
• good service base;
• optimum efficiency.

Among the shortcomings of Russian boilers are:

1. large weight and dimensions;
2. inability to regulate temperature;
3. often outdated design.

Zhukovsky Machine-Building Plant

The plant has been producing heating equipment for over 40 years. The company presents boilers of three series (types) on the market: Economy, Universal and Comfort. Depending on the type, Zhukovsky gas boilers are equipped with imported automation or the development of their own engineers. Automation performs disconnection / connection of the burner, monitoring the temperature in the heating system, monitors the readings of safety sensors and turns off the gas supply to the boiler in the event of a potentially dangerous situation. All ZhMZ models do not require an electrical connection. Among them there are both double-circuit (AKGV) and single-circuit models (AOGV).

Floor-standing gas boilers ZhMZ of the Economy series are equipped with an atmospheric burner, equipped with emergency draft sensors, are easy to set up, and have a high efficiency. However, these models do not provide protection against overheating, which requires a more accurate calculation of the power when purchasing the boiler, as well as periodic manual ignition of the igniter in cases where the protection is triggered. In addition, economy-type appliances require a mandatory annual maintenance procedure before the start of the season.

But for Zhukovsky gas floor heating boilers, the price is so attractive that these minor inconveniences can be ignored. In addition, the listed maintenance features apply only to the Economy series boilers. The automation of the Universal and Comfort models is more perfect (Italian and German production, respectively). These models do not demand service, are reliable and not capricious.

The price is one of the main advantages of Zhukovsky heating devices, but not the only one. In addition to low cost, they have high efficiency (80 - 92%), a high degree of reliability and have a long service life. The standards of the plant, which, by the way, also produces aviation special equipment, are conducive to confidence in the strength and long service life of the heating equipment produced here. If you need a Russian-made outdoor gas boiler, the price of which will be minimal, and the work will be stable, perhaps you should take a closer look at the Zhukovsky models.

Borinsky

Like Zhukovsky, this plant has been producing heating equipment for a long time - more than 20 years. The enterprise produces single-circuit and double-circuit boilers with the usual AOGV and AKGV markings, as well as boilers of its own design of the ISHMA series. All of them are equipped with imported automation, almost all models are non-volatile, have a relatively modern design and low price.

The reviews on Borinsk gas boilers are not bad, they speak especially warmly about the models of the IShMA series - they are additionally equipped with gas pressure sensors, providing devices with an increased level of automation of equipment operation and help to reduce specific gas consumption by about 15-20%. An important advantage of the Borinsk heating appliances is the durability of the AOGV and AKGV budget series due to a reliable cast-iron heat exchanger. True, this affects the cost.

For comparison, the heat exchangers of ZhMZ boilers are made of steel, so they are cheaper. Due to cast iron elements, some models of Borin boilers are also heavy.

For those who are looking for floor-standing Russian gas heating boilers, which are particularly durable, it is worth considering models from Borinskoye OJSC.

In general, if we compare boilers according to the material of the heat exchanger, then some comparative characteristics of cast iron and steel models should be taken into account.

Steel heat exchangers:

• cheaper than cast iron
• easier to transport and install;
• slightly less durable than cast iron.

Modern steel grades with proper operation provide a service life of up to 30 years.

Cast iron heat exchangers:

It should be borne in mind that prices for Russian-made floor-standing gas boilers also partly depend on the material of the heat exchanger.

If you need to buy a single-circuit floor-standing gas boiler that would look attractive, you should also consider Borinsky's proposals. The boilers are covered with polymer enamel, which gives them an attractive appearance: they will fit well into modern interior and will look quite impressive. But there are also disadvantages: increased sensitivity to fuel quality and susceptibility to corrosion.

In general, the heating equipment of Borinsky is perhaps even the most reliable domestic gas floor heating boilers, the prices of which are significantly lower than similar offers from the foreign market. All models of Borinsky boilers are ideally suited for operation in Russia and are characterized by high, up to 90%, efficiency.

"Signal"

The Engel heating equipment plant "Signal" has recently been gaining popularity. His gas boiler Signal KOV-10ST and other models collect good reviews, given the optimal price / quality ratio, however, the installation of Signal boilers can be difficult due to the discrepancy in connector standards. Reviews for this gas boiler Signal are generally positive, as well as for other models of the manufacturer. They attract mainly low price.

There are single- and double-circuit models on the market, imported automation, in operation - moderately capricious.

For many who decide to buy a floor-standing gas boiler, the price often becomes the main selection criterion, but the Russian market offers such a variety of heating equipment manufactured in Russia and the CIS at a relatively equal and affordable price that it is possible in the same price range to choose a model that matches requirements for all key parameters.

Many became interested in the small-sized and attractive design boilers "Pechkin" (Taganrog), choosing as the main argument that, for example, the gas boiler Pechkin KSG-10 is small-sized and equipped with an autonomous continuous water heating system. And someone chooses a gas floor boiler Hephaestus, which has an original water-tube heat exchanger design based on the “Russian stove” principle, which ensures quick and efficient heating of the entire heating system.

You can buy a gas boiler ThermoBar (Ukraine) with a multi-section atmospheric burner that ensures the purity of the combustion products of the fuel, quiet operation and avoids the accumulation of soot in the combustion chamber even during long-term operation of the device. You can read about other popular gas boilers of Ukrainian production. In addition to the manufacturers mentioned above, the Lemax and Rostovgazapparat enterprises stably occupied their niches.

Lemax

The proposals of the Taganrog enterprise "Lemax" will be of interest to those who cannot decide on the type of boiler heating: "Lemax" offers solid fuel heaters that can be easily converted into gas ones. The company offers gas boilers in three types, both single-circuit and double-circuit, the distinguishing features of most of which are a special coating of the steel heat exchanger that protects the boiler from corrosion. There are models with cast iron heat exchangers. All boilers are equipped with imported components, have high efficiency, are non-volatile.

Rostovgazapparat

Rostov equipment is valued for its design feature, which allows complete combustion of fuel. Heat exchangers at this enterprise are made of steel, cast iron and copper. Boilers are equipped with high-quality imported automation.

Noiselessness, environmental friendliness, design, dimensions - any of these parameters can be a decisive argument when choosing. The main thing is that domestic manufacturers have learned how to create heating equipment that is affordable and able to compete with the foreign market.

Each of us wants to install heating equipment that will work not only efficiently, but also economically. Are there economical gas boilers? Depends on what you mean by that. It would be possible to give a list of models with minimal fuel consumption, but everything is relative here, and many factors affect the cost of maintenance. Let's analyze each of them.

The most economical heating boilers

How to reduce gas consumption in the heating system? First of all, you need to choose a device that is suitable for your home. Why is that? Because only taking into account the area of ​​\u200b\u200bthe room, the material of the walls, the number of windows and other factors, it is possible to calculate the required power and performance of the boiler. Only then the equipment will effectively give off heat without consuming excess energy.

If you want to save on gas consumption, then connect only to the general highway. Balloons are very expensive. What criteria affect the economy:

• Design features;
• Efficiency factor (COP);
• The power of technology;
• fuel quality;
• Optimal mode.

Let's go through each point in more detail.

Equipment design

Heating boilers come with one and two circuits. A single-circuit device is designed only for space heating, and for hot water supply (DHW) you will have to additionally connect a boiler. But double-circuit models already include everything you need for heating the house and for hot water supply.

To calculate the savings, pay attention to the type of combustion chamber. An open chamber takes air from the room to maintain combustion and exhaust gases. Closed, forcibly drives air from the street. The removal of combustion products is carried out by a fan. This principle contributes to the complete combustion of the fuel, as well as the minimum emission of CO2.

Closed-type appliances are connected to a coaxial chimney. Its tube-in-pipe design traps more heat. Therefore, the air from the street is heated, which increases the efficiency of combustion.

Influence of efficiency

Today the market offers the buyer and condensing boilers. Which one is more economical? It is believed that condensation, because it uses the energy of condensate. When taking into account additional energy, a conventional unit has an efficiency of 92-94%, and a condensing one - 100-102%.

Standard work is to burn fuel and exhaust gases to the street, which have a high temperature. Combustion products contain impurities and moisture. Passing through the heat exchanger, the gases reach 60°. Because of this, sediment falls out and accumulates in the tank. In the process, energy is released, which is used by the condensing device. It is believed that this can save up to 20% of fuel. But even here there are "pitfalls". Such units are installed to low-temperature systems with underfloor heating.

There are also a number of other nuances that we described in the article "".

What affects the efficiency of a convection boiler:

• Physical malaise. When air is burned instead of gas. affects the quality of the fuel;
• Chemical burn. Depends on the amount of carbon monoxide in the combustion process;
• Poor insulation, wall insulation.

How to set up optimal performance:

• Clean the system at least once a year. Remove scale from the heat exchanger, soot from the burner and tubes;
• Put a damper on the pipe to restrict air flow;
• Clean the soot from the parts of the combustion chamber, otherwise the gas consumption will increase.

Equipment power

The power of wall and floor boilers is different. Mounted heat rooms up to 300 m². But the floor can heat huge areas. The optimum coolant temperature depends on the power. Why is this indicator important?

There is such a thing - boiler clocking. This is the frequency of turning the heating on and off depending on the temperature drop. A device that is too powerful will not be able to operate in optimal mode - the manufacturer takes this into account when indicating the efficiency of the model. The appliance will turn on frequently and the rest interval will be short.

Weak equipment, on the contrary, will wear out quickly, as its work will go to the limit. Before buying, pay attention to the optimal power - this is 75% of the maximum performance.

How to economically set up equipment

We examined the main factors that affect the degree of fuel consumption. How to choose the right boiler and use it so as not to overpay the bills?

Power calculation

What factors are taken into account:

• Room dimensions;
• Wall materials, the presence of insulation;
• Availability of additional heating radiators;
• number of windows;
• Climatic zone.

It is best to entrust the calculation to a specialist. In the future, you will be able to save on operation thanks to this.

Technical condition

Timely carry out technical inspection, prevention of breakdowns. Install water filter to reduce salt accumulation. When water is heated, scale is deposited in the heat exchanger tubes. It interferes with heat transfer, so that the device begins to consume more gas. Therefore, you should periodically clean the radiator from deposits.

Also remove dust and soot from taps and parts.

Gas quality

You cannot influence this factor as well as the pressure drops in the line. But you can choose equipment with maximum adaptation to Russian conditions. Then it will work stably even with pressure drops.

Optimal Mode

What temperature to set? You yourself choose the temperature for the normal operation of the boiler. For example, you set the value to 55 degrees - which means that the unit will constantly work at this temperature. But the weather outside the window in winter changes: it gets cooler, then warmer. It is clear that because of this, the temperature in the room becomes less comfortable. How to fix it and even save money? Let's reveal the trick: you need to install an automation system.

In new models, it is already built in, and if yours is not, it is not a problem to buy it. This includes control sensors and an external thermostat. The latter measures the temperature in the house, thanks to which the mode is regulated. The equipment will respond adequately to temperature changes, consume less resources.

Another savings secret: set a lower temperature for the night.

To all of the above, let's add good insulation walls and windows: this will give +20% energy to the piggy bank.

Brand and manufacturer

Remember, we wrote that the efficiency of technology is relative? This is true. But still more economical in terms of efficiency are foreign models: "", "",. The documentation of Russian and foreign manufacturers may indicate the same percentage of efficiency. But we know that the same Germans approach the assembly of equipment more carefully and scrupulously. On the other hand, do not forget that most foreign models are assembled in China or here in Russia.

Conclusion: the most economical boiler - correctly selected in terms of power, efficiency, build quality. During operation, this is affected by maintenance, prevention of breakdowns, and the set mode. We hope our article will help you make the right choice and "legally" reduce gas consumption.

Today's market for heating equipment will satisfy the needs of any buyer, and offers are no exception. Here you can find many models of both budget units and expensive top-end equipment. In conditions of such saturation, it is difficult to determine which gas boiler is the most reliable, especially if you have not had to buy these devices before.
