The best gas heating boilers according to user reviews

Gas, firewood, coal, electricity – which is cheaper?

In the medium term, the cheapest fuel for the boiler is natural gas. To generate 30 kW, only 2.75 cubic meters of such fuel is sufficient (taking into account 91 percent efficiency and the calorific value of a cubic meter of fuel at 43,000 kJ). In 2015, one thousand cubic meters of gas in the European part of Russia cost about 5,000 rubles. As a result, “production” of 30 kW using a gas boiler costs no more than 13.75 rubles.

Heating with coal burned in the firebox of a solid fuel boiler will cost a little more. To generate 30 kW, 8 kilograms of coal are required (taking into account 80 percent efficiency and the calorific value of a kilogram of fuel at 17,000 kJ). In 2015, a ton of ordinary coal cost about 4,000 rubles. Generating 30 kW using a coal boiler will cost 32 rubles. But coal will have to be stored somewhere. And the delivery of such fuel is not cheap.

Heating a house with wood alone will cost much more. If you load dry wood into a solid fuel boiler with a calorific value of 14,000 kJ per kilogram of fuel, then to generate 30 kW, taking into account the 80 percent efficiency of the boiler, you will have to spend almost 10 kilograms of firewood. In 2015, the cost of a cube of firewood (650 kilograms) delivered to your home in the form of a packaged woodpile reached 3,000 rubles. As a result, generating 30 kW using a wood-burning boiler will cost 46-47 rubles.

How to take ceiling heights into account when calculating?

Since many private houses are being built according to individual projects, the methods for calculating boiler power given above will not be suitable. To make a fairly accurate calculation of a gas heating boiler, you need to use the formula: MK = Qt*Kzap. Where:

• MK – design power of the boiler, kW;
• Qt – predicted heat loss of the building, kW;
• Kzap is a safety factor that is 1.15 to 1.2, i.e. 15-20%, by which experts recommend increasing the design power of the boiler.

The main indicator in this formula is the predicted heat loss of the building. To find out their value, you need to use another formula: Qt = V*Pt*k/860. Where:

• V is the volume of the room, cubic meters;
• Рt - difference between external and internal temperatures in degrees Celsius;
• k is the dissipation coefficient, which depends on the thermal insulation of the building.

The dissipation coefficient varies depending on the type of building:

• For buildings without thermal insulation, which are simple structures made of wood or corrugated iron, the dissipation coefficient is 3.0-4.0.
• For structures with low thermal insulation, typical for buildings with single brickwork with ordinary windows and a roof, the dissipation coefficient is taken to be 2.0-2.9.
• For houses with an average level of thermal insulation, for example buildings with double brickwork, a standard roof and a small number of windows, take a dispersion coefficient of 1.0-1.9.
• For buildings with increased thermal insulation, well-insulated floors, roofs, walls and double-glazed windows, a dispersion coefficient of 0.6-0.9 is used.

For small buildings with good thermal insulation, the design power of heating equipment can be quite small. It may happen that there is simply no suitable gas boiler on the market with the required characteristics. In this case, you should purchase equipment whose power will be slightly higher than the calculated one. Automatic heating control systems will help smooth out the difference.

Some manufacturers have taken care of the convenience of customers and have placed special services on their Internet resources that make it possible to calculate the required boiler power without any problems. To do this, you need to enter the following data into the calculator program:

• temperature that must be maintained in the room;
• average temperature for the coldest week of the year;
• need for hot water supply;
• presence or absence of forced ventilation;
• number of floors in the house;
• ceiling height;
• information about floors;
• information about the thickness of external walls and the materials from which they are made;
• information about the length of each wall;
• information about the number of windows;
• description of the type of windows: number of cameras, glass thickness, etc.;
• dimensions of each window.

Once all the fields are filled in, you can find out the estimated power of the boiler. Options for detailed calculations of the power of boilers of various types are clearly presented in the table:

This table has already calculated some options, you can use them as the correct ones in advance (click on the picture to enlarge)

Installation and connection instructions

The installation of a gas boiler begins only after studying the regulations and permits. The entire installation process consists of the following steps:

1. Preparing the base. A concrete screed is installed on the floor covering and a metal sheet is laid. The device is placed parallel to the floor.
2. Chimney installation and draft assessment.
3. Connecting heating system pipes. A fine filter is pre-installed, which is combined with the return pipeline in front of the boiler. Ball valves are installed on both sides of the device.
4. Connection to water supply. The procedure is needed for 2-circuit devices. The supply pipe is cut into the upper part, and the outlet pipe - at the bottom.
5. Connection to the gas supply system. This procedure can only be performed by an expert in the gas industry.

To ensure safe operation of the boiler, you must follow the connection diagram and take into account the following requirements:

1. The unit can only operate at normal humidity levels.
2. The system must be maintained at least once a year. Modern boilers implement advanced testing methods that automatically detect errors and display them on the display.
3. Use of fine filters.
4. Organization of natural or forced ventilation in the room with the device.
5. The presence of traction of at least 10-20 m/s.

Proper operation of the boiler involves regular maintenance and monitoring of the equipment. The owner of the device must take the following measures:

1. Check gas pipeline taps.
2. Inspect thermostats on floor-standing units.
3. Wash or replace filters.
4. Regularly assess the condition of the nozzles and monitor the tightness of the door.
5. Monitor the traction in the excretory tracts.
6. Clean the coaxial chimney of a wall-mounted boiler from ice in winter.

By following simple rules and tips, you can extend the life of the device and reduce the consumption of blue fuel.

How to choose a good gas boiler?

Question, can you help me choose a good gas boiler for a small house? Any construction must begin with design; it is advisable to entrust this difficult task to professionals.

It is preferable for this company to be an experienced one that has experience in architectural design, construction, reconstruction, and design.

The most common are gas boilers for providing the home with hot water and heat with a capacity of 24-28 kilowatts

For example, it may seem that choosing a good gas boiler for heating your home is not a difficult matter. But still, the average person may not know all the nuances that are important when choosing heating equipment. If you are dealing with professionals, then you can fully count on advice on this issue. If you have no one to consult with, we hope that the information below will help you.

After this period, electronic malfunctions begin, mainly error 01 - problems with ignition. And it’s good if you only need to change the sensors. Most often, the control board fails and, due to its exorbitant price, is no longer worth replacing.

Selecting the site schoolremont.ru

A good wall-mounted gas double-circuit boiler 24-28 kW costs, on average, from 35-4500 rubles. Such a unit is enough to heat a two-story house with an area of ​​up to 300 m3.

To choose the right one, it is not enough just to find out the prices for wall-mounted or floor-standing boilers: you should, first of all, take into account the features of their installation and operation. Knowing the basic characteristics won't hurt either.

What power should I choose for a gas boiler?

Power is the main indicator characterizing any heating equipment for the home. It is determined by the amount of heat loss in the living space and depends on how thoroughly the room is insulated. Heat loss can vary from 70 to 250 W/sq.m.

Please note that the double-circuit gas unit will also be used to heat water.

Of course, the need for hot water may vary - the presence of a shower, bath, sink, or sink should be taken into account. But the most common are gas boilers for providing the home with hot water and heat with a capacity of 24-28 kilowatts. Such equipment will last about 10 years and will heat a cottage up to 300 m2 in operating mode up to 70% of the declared power.

Dual-circuit

Obvious differences:

• Single-circuit boilers are suitable when only room heating is required. The boiler is installed separately;
• A double-circuit one is capable of providing a home with hot water without additional devices such as a boiler. Of course, such a boiler is more profitable, it is compact and its dimensions are small. A double-circuit gas boiler is often used according to the scheme: First circuit - first floor, second circuit - second floor.

on this topic:

Undoubtedly, gas boilers are the most popular, because they are the most economical. Usually, there are no problems with connection: gas lines are now widespread. However, this pleasure is not cheap, up to 1 million rubles. Just remember that you need to calculate the gas pressure.

If you still want to go with an electric boiler, then consider some points:

• To connect it, there must be a three-phase voltage, and considerable costs will also be required for its maintenance. Such a boiler consumes 24 kW per hour, while a gas boiler consumes 2.8 cubic meters. But the electric one is compact, does not require a chimney, and is easy to maintain.
• However, electric boilers are certainly the only option when there is no gas main nearby. For such settlements, of course, it is more profitable to install two-tariff meters and heat the house with an electric boiler from 23.00 to 06.00 in bulk in order to save money.

Wall or floor?

The difference between floor-standing and wall-mounted boilers is the material the heat exchanger is made of. Usually, good wall-mounted models of gas boilers have copper and the power will be limited to 35 kW; the service life of the device is not very long. Pros: compactness, light weight, presence of all necessary components in the body.

Floor-standing boilers have cast iron heat exchangers, they have unlimited power and last a very long time.

But they are heavy, take up quite a lot of space, and additional devices such as a pump, a safety group, and an expansion tank must be installed.

review:

Don’t rush to make a choice, take into account all the technical nuances. A good gas boiler does not have to be expensive. Don't try to buy timeless equipment. It is better to replace it with the same model after 10 years. Safety, automation, efficiency and, of course, a manufacturer with a name also matter.

The best solid fuel boilers 2022 - 2019

The heating system is one of the integral communications of the building. And here progress also does not stand still: every year manufacturers delight with new units.

To make a good choice, it is necessary to take into account that each solid fuel boiler is designed for a certain power and, accordingly, may have a limitation on the size of the heating area.

The efficiency of the device and the type of control also matter; for example, the presence of an automatic ignition function will significantly simplify operation.

We have compiled a rating of the best new products for 2022 - 2022. According to buyers, these particular solid fuel boilers have the best price-quality ratio, ease of operation and attractive appearance. They are the most in demand and have already proven themselves worthy. So, let's look at our top 10.

Combination boiler for medium-sized areas - up to 200 sq.m. This model from a domestic manufacturer opens our rating of the best boilers of 2022 - 2022. It is possible to install a burner (also not included in the package). Has high heat transfer. The coolant temperature is from 50 to 90 degrees. The product lights up quickly and maintains a good temperature for a long time.

Minuses:

• You must purchase a pellet or gas burner yourself.
• A small hole for storing firewood.

A budget option with good power is an excellent choice for a small private house or cottage. The manufacturer recommends using wood and charcoal to operate this boiler. The removable damper ensures easy cleaning of the coolant.

conclusions

Selecting heating equipment is a complex and responsible task. You should not immediately pursue models of solid fuel units that have more power. In some cases, for heating a residential building, installing a unit with output parameters of 24-36 kW is sufficient. At a temperature outside the window of -30 0 C, such a boiler will make it possible to create a temperature inside the room of +20-22 0 C and heat the water in the hot water system to 40-45 0 C.

In each individual case, you can make a choice in favor of one type of heating technology or another.

Higher boiler power may be required in peak situations, when climatic conditions force the heating system to work in increased mode. However, such situations are not systematic, and most of the time your heating device will operate at reduced settings. If you expect a large consumption of hot water for domestic purposes, then you should immediately focus on equipment with higher power. In modern private homes, more than 50% of the power of heating equipment is used to provide hot water to the inhabitants of the house. Connecting a “warm floor” heating system also forces you to pay attention to boiler equipment with higher power.

You need to select a boiler not only based on its actual power. The operational capabilities of heating equipment, the method and quality of maintenance of boiler equipment play a role here. Using the optimal type of fuel for your heating equipment, the presence of automation will allow you to achieve normal operation of your solid fuel boiler.

Which gas boiler is better to buy?

The power of heating equipment is the first thing you need to determine before purchasing. It is calculated using the heating area taking into account the climate zone. At first, with a standard ceiling height of up to 3 m, you can get by with simple calculations: multiply the housing area by the coefficient for your region, and divide the total by 10. As a result, you will get the approximate boiler power in kW.

Power factors for different regions of Russia:

1. southern region 0.7-0.9

2. middle band 1-1.2

3. moderately cold climate 1.2-1.5

4. northern region 1.5-2

According to calculations, for a house with an area of ​​100 square meters in the middle zone, a boiler of 10-12 kW will be required. When purchasing a dual-circuit unit, the total power will increase by 20%.

Not only the organization of space, but also the safety of using gas equipment depends on the method of installing the boiler. Wall mounting will save space, but the compactness of the model will entail a number of technical limitations. The burner, exchanger, pump and control electronics will be too close to each other, which will create an intense temperature regime for their operation and complicate maintenance.

Compact wall-mounted models have power limitations - they are more suitable for an apartment than for a private house. Floor-standing boilers, as a rule, are installed in separate rooms, so their overall dimensions, as well as thermal power, are not limited by anything other than common sense.

The types of gas burners do not depend on the type of boiler chosen, but determine the principle of its operation and performance:

• Atmospheric burners are inexpensive and almost silent. But they burn out the air in the room and have low efficiency.
• Supercharged ones are equipped with an air supercharger supplied from outside. Boilers with such burners are efficient and do not require installation in a separate room.
• Modulating burners with adjustable power can be equipped with a second heating stage or electronic heat transfer control. Their efficiency and cost-effectiveness increases simultaneously with the price of the boiler.

Useful tips

The smaller the volume of coolant in the heating system of a private house, the more efficiently the electrode-type boiler operates. Therefore, it is recommended to use bimetallic or aluminum radiators and contour wiring made of polyethylene pipes to construct the heating system.

Please note that it is best to create your own new heating for an electrode heating unit. It is not worth embedding it into an old one, where another type of heating device was used.

Thermal insulation and connection

Experts recommend thermal insulation of all circuits. The connection is best done with a separate cable from the distribution panel with the installation of a separate machine. An RCD (residual current device) cannot be installed in the electrical connection circuit.

The installation must be grounded, as is the case with other models of electric heating units.

Increasing heating efficiency

If the power of one boiler is not enough to heat a large house, then several devices can be installed in a single system. They can be connected to each other in parallel or in series.

And one last thing. Heating boilers of this type are installed only in a closed system where a circulation pump is installed. The latter provides additional coolant resistance, which affects the quality of heat generation.

Baxi ECO-4s 1.24F is able to function uninterruptedly both during power surges and when pressure drops in the line. Conveniently, the company has provided the ability to directly connect to solar panels. Almost all reviews for this model are positive. Even after 3 years of constant use, there are no breakdowns or malfunctions. The downside is the inconvenient location of the monometer.

Why contact a specialist?

We found out that buying a boiler from the square is wrong. It is important to consider the heat loss of the building. For example, a house of 300 m² can be heated by a 15 kW boiler if all surfaces are thoroughly insulated. And a house of 150 m² may require 30 kW equipment with thin walls and uninsulated roof and ventilation.

There are hundreds of standards and regulations on this topic, there are dozens of formulas. Sometimes one thing contradicts the other, or standards change and it is difficult for a non-professional to understand whether these requirements are relevant. You can calculate all this armed with a stack of reference books. Or contact specialists who will make accurate calculations in the program and explain all the details. They will help you save money, time, and model an efficient home heating system.

How to solve the problem of high power and weak demand?

In an ideal situation, the boiler operates at a constant, rated output. At the same time, the outside temperature is constantly changing, and there are even abnormal jumps. What to do? Four-way mixing valves in the hydraulic system will help. Or an option with thermo-hydraulic distribution. These devices solve the problem not by adjusting the boiler power, but by adjusting the control valve. Or the speed of the circulation pump changes. The temperature of the coolant in the batteries becomes comfortable without disturbing the optimal conditions of the boiler. This solution has a minus - a high price.

For gas and liquid fuel boilers, multi-stage burners solve this situation. A lower stage reduces the boiler power if necessary. Advanced models have a smooth adjustment of burner power - modulation. It is cheaper and not as troublesome as the first option.

Solid fuel boilers also have built-in power settings and automatic fuel supply. This helps solve the issue of excess power when the external temperature changes.

Gas or solid fuel - which is better for 150 square meters?

• Gas boilers are more compact than solid fuel units. The average dimensions of a 20-kilowatt gas boiler (height x width x depth) are 75 x 40 x 35 centimeters. The dimensions of an ordinary solid fuel boiler are 90 x 40 x 65 centimeters. The pyrolysis boiler takes up even more space - 130 x 60 x 90 centimeters. Therefore, if the house does not have a boiler room, then it is better to choose a gas boiler. It can be hung on the wall literally anywhere – even in the hallway.
• In the segment of double-circuit boilers, there are much more gas models than solid fuel ones. At the same time, at the purchasing stage, the former are 2-3 times cheaper than the latter. The average cost of the gas option is 30-40 thousand rubles. In turn, a solid fuel double-circuit boiler costs from 80 to 120 thousand rubles.
• The cost of operating a gas heater is comparable to that of a solid fuel option. The first consumes from 1.2 to 2 cubic meters of gas, and the second from 1.8 to 2.5 kilograms of solid fuel.
• A solid fuel boiler operates from one fuel load to the next. Even the most advanced models - long-burning boilers - will have to be loaded once a day (with wood) or once every three days (with coal). Of course, you can use a bunker pellet boiler to heat your home - for a house of 150 sq.m. A storage capacity of 0.5-1.5 cubic meters is sufficient, replenished several times a month. But the autonomy of a gas unit “refueled” from a main pipe is far from any solid fuel option.

As a result, the gas heater looks more convincing. It is compact, economical and operates unattended

Therefore, you should pay attention to the solid fuel option only if there is no main gas pipeline. Since “powering” with liquefied fuel deprives a gas boiler of all advantages over a solid fuel heating device

Electricity is actively used when arranging one’s own heating system, especially in non-gasified areas of the country.

It eliminates the need to stock up on fuel and install chimneys.

One of the popular options is an electric boiler for heating a house of 150 square meters.

This powerful equipment requires a particularly careful approach in choosing a model.

To do this, you need to understand the requirements and selection criteria.

Why should you install EcoLine?

To see the benefits of infrared heating, consider a real example:

The task is to heat a separate building with an area of ​​100 square meters. m., ceiling height 4.5 meters. The building has good insulation, one gate, the windows are double glazed with a total area of ​​5 sq. m. m. Required temperature during working hours from 10:00 to 18:00 20 degrees Celsius, during non-working hours 10 degrees Celsius. The building is located in the Moscow region.

From the thermal engineering calculation it is clear that for heating 100 sq. m. You will need to install three EcoLine heaters and spend 22,720 rubles on the purchase of equipment. There will also be small additional costs for installing a heating system and purchasing a thermostat, but they should not exceed 100% of the cost of the equipment. Agree, installing a gas boiler or laying central heating pipes with the installation of radiators in the room will cost much more.

The main point in the thermal calculation that you need to pay attention to is the annual heat consumption (kW). In our case, it is equal to 19,048 kW. multiply by the cost of 1 kW/h, in our case equal to 4 rubles, divide by 12 months and get that heating is 100 kW

m. will cost 6349.33 rubles/month. Agree, it's not that expensive! And if you take into account that maintaining the system requires virtually no annual costs. And if the room will not be used for some time, then the heaters can simply be turned off, unlike water heating, when you have to drain the water from the pipes

multiply by the cost of 1 kW/h, in our case equal to 4 rubles, divide by 12 months and we get that heating is 100 m2. m. will cost 6349.33 rubles/month

Agree, it's not that expensive! And if you take into account that maintaining the system requires virtually no annual costs. And if the room will not be used for some time, then the heaters can simply be turned off, unlike water heating, when you have to drain the water from the pipes

Also, in case of moving or selling a premises, the EcoLine heating system can be easily dismantled, transported to a new location and installed, which cannot be said about water or gas heating.

The question may arise, why install EcoLine if you can install cheaper convective electric heaters of the same power? Yes, of course, you can go this route and save 20-30% on the cost of equipment on your initial purchase. But the very principle of heating a room with convective heaters involves heating the air, and as we know from a school physics course, warm air rises to the top, overheats, and only after many hours of operation of convective heaters does a person begin to feel warm. With infrared heaters everything is different. Infrared rays travel through the air space with virtually no loss and heat up solid objects and you and me, so within the heater’s coverage area, after just 10 minutes of operation, a person feels a comfortable warmth. The thermostat clearly responds to changes in room temperature and controls the operation of infrared heaters automatically. This leads to the most efficient operation of the heating system, eliminating unnecessary energy consumption. Therefore, EcoLine ceiling heaters are almost two times more economical to use compared to convective heaters. And simple calculations show that the cost of purchasing infrared heaters, compared to convective devices, pays off within two months.

Bottom line: we can definitely say that with heating 100 sq. m. EcoLine infrared heaters will cope in the best way, both at the level of initial costs and in subsequent maintenance.
