When the gas main runs far from a populated area, diesel boilers help create a comfortable microclimate in the house. They allow you to organize a heating system with minimal intervention from the residents of the house. The advantages of the liquid heating method include economical consumption and the ability to automate the operation of the device. The Russian trading network offers a wide range of domestic and foreign models. Our experts will help you choose the optimal diesel boiler, taking into account the terrain and size of the house.

general information

If in the past homeowners who did not have a connection to a gas pipeline chose exclusively solid fuel boilers, today devices running on diesel fuel are becoming more and more relevant. This is explained by the improvement of the design of such installations, their simultaneous power, efficiency and complete safety in operation. The use of special nozzles and improved combustion chambers can significantly increase efficiency. The premises are heated efficiently, while utility bills are reduced.

Modern diesel fuel boilers for the home are fully controlled by automation, which monitors all operating parameters. This allows you to reduce or increase the heating intensity. Servicing such heating equipment is not particularly difficult, so you can do it yourself. The latter favorably distinguishes diesel boilers from gas installations, for the maintenance of which it was invariably necessary to contact the appropriate gas services, and the cost of such work was extremely high.

In this video we will look at diesel heating:

How to choose the best option

When purchasing equipment, you need to pay attention to such characteristics as:

• efficiency;
• heating area;

• power consumption
• fuel consumption.

An important indicator of equipment performance is the type of burner used. In boilers operating on gas and liquid fuel, replaceable burners are installed. The presence of a diesel fuel heating system allows you to reduce fuel consumption.

Design Features

The design of boilers operating on inexpensive diesel fuel is simpler than electric and gas ones. Such installations may be non-volatile or require an electrical connection. Taking into account the availability of electricity in the house, you can choose the appropriate boiler model and completely solve the problems with heat in the house. The diesel boiler includes the following elements:

• diesel burner:
• High pressure pump;
• fuel filter;
• coolant temperature sensors;
• pressure gauge;
• Remote Control.

The operating principle of the unit is extremely simple. A pump from the tank forces fuel into the system, which enters the burner under high pressure and is sprayed into a fine mixture in the combustion chamber. Further, due to the high pressure, the diesel fuel ignites in the burner. Hot gases heat the coolant , after which they are discharged outside through a coaxial pipe and chimney. Despite the simplicity of the design, such units are extremely efficient, allow you to quickly heat the room, and thanks to the use of control automation, they are characterized by excellent fuel efficiency.

Modern diesel heating boilers are safe to use. According to this indicator, they look preferable to natural gas installations. The operation of such equipment is fully controlled by automation. Built-in sensors monitor system pressure and proper combustion of fuel in the burner and, if necessary, make appropriate adjustments.

The presence of built-in control and automation units with developed logic allows you to optimally configure the operation of the equipment. It is possible to quickly reduce or increase the power of the boiler. You can set the heating so that the optimum temperature is maintained or the equipment turns on at certain hours. This ensures maximum efficiency and proper heating of the house while saving fuel.

Fuel consumption figures

Previously, the disadvantage of such equipment was mediocre fuel efficiency, which somewhat limited its prevalence in the domestic market. However, today, with the development of technology and the advent of automatic control systems, diesel boilers began to consume less fuel, while at the same time their efficiency increased. Even when using a low-power unit, you can successfully heat a dacha or a small private house.

Calculating the fuel consumption rate of such boilers will not be difficult. For this calculation, a universal formula is used, in which the boiler power is divided by ten and the diesel fuel consumption per hour for operating the equipment at its full power is obtained. Accordingly, if a unit with a power of 20 kW is used and it operates at full power, then it will consume 2 liters of fuel per hour. Such consumption figures are observed only at maximum power ; in reality, diesel fuel consumption will be much less.

Boiler selection

The efficiency of the heating system will directly depend on how correctly the heating boiler is selected for a private home. Now there are dozens of different models on sale, which differ in power, the presence or absence of a second heating circuit and control automation, as well as a number of other important parameters.

When choosing fuel equipment for cottages and country houses, the following factors must be taken into account:

• building area;
• type of coolant used;
• climate in the region;
• mode of living in the house in winter;
• presence or absence of insulation;
• wall materials used in construction;

If the house is built from heat-efficient materials and has good insulation, the homeowner has taken care of high-quality windows, and the climate in the region is not too harsh, then there is no need to purchase a heavy-duty diesel boiler. A unit with a power of 5-8 kW will be sufficient, which will cope with heating a house with an area of ​​about 100 m².

To heat a large two-story building, a diesel boiler with a power of 12-15 kW is enough. Such equipment will be equipped with automatic control; it consumes a minimum of diesel fuel, while a solid reserve of power will be enough to quickly heat the premises. To install a powerful boiler, you will need a properly organized boiler room with high-quality ventilation of the room.

If the house is not connected to a hot water supply, then it makes sense to purchase a double-circuit diesel boiler, which can simultaneously both heat the house and solve the problem with hot water.

Proper maintenance of equipment

The trouble-free operation of a diesel heating boiler will largely depend on the timeliness and quality of equipment service. This work is not difficult, so the homeowner can do it himself without turning to specialists.

When diesel fuel and oil burn in the burner, ash and soot are formed. Such contaminants settle on the combustion chamber, injectors and other elements of the fuel system, which impairs its performance. A 2 mm thick layer of soot and ash on the walls of the combustion chamber can lead to an increase in fuel consumption by 10%. By cleaning the burner from carbon deposits, the owner not only extends the life of the equipment, but also maintains optimal fuel consumption.

Cleaning a diesel boiler for a home can be done either manually or using special spray chemicals, which can be easily purchased in specialized stores. It is recommended to clean the combustion chamber from ash and soot once a month. If the unit is actively used, when in winter it operates at high power around the clock, cleaning may be required once every two weeks or more often.

Review

Design and principle of operation of a diesel boiler

The design of units using liquid fuels as an energy carrier requires the following basic elements:

• Housings with a built-in combustion chamber;
• Burners in which the formation of a combustible mixture occurs;
• One or two heat exchangers;
• Fuel pump;
• Filtration systems;
• Thermal sensors;
• Electronic control and settings unit.

The material for the manufacture of heat exchangers can be steel or cast iron. Some premium diesel boilers are equipped with heat exchangers made of high-alloy heat-resistant steel.

The fuel entering the burner is mixed with air, thus forming a fuel mixture, which is sprayed through the nozzle into the combustion chamber. The completeness of fuel combustion depends on the correct adjustment of the burner itself and the quality of the nozzle. The fuel mixture entering the combustion chamber is ignited by a spark generated by an automatic control system (ACS), and the heat generated during the combustion process is transferred to the coolant through the walls of the heat exchanger.

The temperature of the coolant is controlled by a system of temperature sensors installed in the combustion chamber. When the set temperature regime is reached, the automatic control system turns off the burner, and when the coolant cools, the combustible mixture is automatically ignited. Exhaust gases are discharged through the chimney.

The burners of diesel heating boilers can be fan-driven or forced-air. In fan burners, excess pressure is created using a special built-in fan. The performance of such modules is quite high, but the operation of the installations is accompanied by an increased noise level.

In forced-air burners, a turbine is installed instead of a fan. The use of turbocharging can significantly increase the productivity of the installation and achieve complete combustion of the combustible mixture. Removal of exhaust gases from the combustion chamber can be done either naturally, due to the draft generated in the chimney, or forcefully, using a fan.

Another design feature of a diesel fuel boiler for heating a private home is the possibility of conversion to work with other types of fuel, in particular natural gas, for this you just need to replace the diesel burner with a gas one.

Diesel boilers with power from 7 to 10 kW

Equipment up to 10 kW is not equipped with diesel burners and is designed for connection to a centralized gas supply or liquefied gas cylinders. To ensure quick heating, radiators with fins are used; manufacturers use multiple circulation of combustion products.

Advantages and disadvantages of diesel boilers

Like any other equipment, diesel boilers have their strengths and weaknesses. The advantages of such units include:

• The device is fully automated and can operate autonomously without operator intervention. The duration of continuous operation is determined solely by the capacity of the fuel tank.
• If the automation is working properly, boiling of the coolant is almost impossible, since the power of the installation can be instantly reduced to a minimum by turning off the fuel supply.
• When stored, liquid fuel takes up much less space than a stock of coal, firewood or pellets.
• Possibility of using waste oil and other liquid combustible waste as an energy carrier.
• Unlike gas boilers for heating a private home, the installation of diesel heating equipment does not require coordination with the relevant services and can be done on its own.

Fuel consumption of diesel heating boilers

Since the cost of diesel fuel is quite high, fuel consumption is one of the most important characteristics of the installation. Overconsumption of energy leads to a significant increase in material costs for heating a home. Increased fuel consumption may occur due to the following reasons:

• Incorrect burner adjustment
  . Complete combustion of fuel is possible only with an optimal ratio of fuel and oxygen in the combustible mixture, otherwise diesel fuel consumption increases significantly.
• Thickening of fuel
  . With a significant decrease in temperature and insufficient thermal insulation of the supply pipelines, the viscosity of diesel fuel increases, which inevitably leads to an increase in fuel consumption.
• Nozzle or injector failure
  . Under the influence of high temperatures, the injector nozzle gradually burns out, which leads to improper atomization of the combustible mixture and, as a result, to increased fuel consumption.
• Climatic conditions
  . In severe frosts, more diesel fuel is required to maintain a given temperature.

There are a number of ways to reduce diesel fuel consumption while ensuring the necessary temperature balance in the house, these include:

• Careful burner adjustment. The use of specially developed software allows you to reduce the fuel consumption of a diesel heating boiler for a private home by 10 - 15%.
• The use of room temperature sensors and automation that monitors changes in external temperatures reduces fuel consumption by 15%.
• Thermal insulation of external storage facilities and supply lines.
• Correct choice of power characteristics of the unit.

When these conditions are met, diesel fuel consumption is reduced by 25–30%.

Determination of average fuel consumption

At the household level, we can assume with a reasonable degree of accuracy that with a power of 10 kW, a diesel boiler consumes 1 liter of fuel per hour, provided that the heat is spent exclusively on heating the house. When using a double-circuit boiler, diesel fuel consumption increases by an average of 30%.

Considering that heating 10 m2 of living space requires approximately 1 kW of thermal power, for efficient operation of the heating system in a house with an area of ​​100 m2, a heat generator with a capacity of 13 - 15 kW will be required. Such an installation consumes 1.3 - 1.5 liters of diesel fuel per hour, therefore, from 30 to 32 liters will be consumed per day. Provided it operates in nominal mode throughout the heating season, fuel consumption will be from 4.5 to 5 tons.

How to calculate the required boiler power

For calculations, you can use the method of determining the minimum power depending on the area. To increase accuracy, the insulation of the walls of the room should be taken into account; losses depend on the material. For example, when using timber or installing a protective layer of mineral wool up to 150 mm thick, it is necessary to lay at least 0.5 kW for every 10 m² of area. In the case of improved insulation and the use of double-glazed windows, the value of heat losses is reduced to 0.4 kW.

The apartment owner can determine the parameter based on the methods set out in SNiP standards, which establish heat consumption coefficients:

• 0.034 kW/m³ for brick buildings;
• 0.041 kW/m³ for panel houses.

After measuring the area and determining the volume of the room, a calculation is made. For example, for a 120-meter apartment in a panel house with a ceiling height of 2.7 m without additional thermal insulation of the walls, you will need a boiler with a capacity of 120 * 2.7 * 0.041 = 13.2 kW. The rule applies when using standard windows, installing radiators along external walls and having working heating in neighboring apartments.

The boiler power is calculated depending on the area of ​​the room.

A formula of the form Q=1000хSхk1…хk10 is also used, where:

• Q – power in kW;
• S – area in m²;
• k1 – coefficient of the number of walls bordering the street;
• k2 – correction for room orientation;
• k3 – coefficient of thermal insulation of walls;
• k4 – correction for minimum temperature;
• k5 – ceiling height indicator;
• k6 – indicator of heat loss through the ceiling panels;
• k7 – window efficiency coefficient;
• k8 – indicator that takes into account the total glazing area;
• k9 – radiator connection indicator
• 10 – coefficient of location and shielding of batteries.

Criteria for choosing a heating boiler using diesel fuel

When choosing a diesel heat generator, special attention should be paid to the following aspects:

Thermal power of a diesel boiler. In general, it is generally accepted that to effectively heat an area of ​​10 m2 in the middle zone, 1 kW/h of thermal energy is required; in cold regions this figure can be 1.3 – 1.4 kW/h.

Possibility of temperature control. There are three main types of liquid fuel installations:

With a single-stage burner, constantly operating at maximum mode;

With a two-stage burner, providing the ability to operate in 50 and 100% modes:

With an adjustable burner that allows settings over a wide range, which significantly reduces energy consumption.

Fuel consumption. It is this indicator that determines the economic feasibility of using a diesel unit; in addition, based on these data, it is possible to prepare in advance the necessary fuel supply for the entire heating season.

In addition, one should take into account the possibility of creating a hot water supply circuit and converting the installation to use natural gas, in the case of a centralized pipeline supply.

conclusions

Diesel hot water boilers have a power from 7 to 3500 kW and are designed for installation in buildings not connected to the gas supply system. When using the equipment, it is necessary to provide a fuel tank located in the ground or in a separate fireproof room. The capacity of the tank depends on the efficiency of the equipment and the ease of supplying fresh portions. If access to the building is difficult in winter, and the fuel supply is not designed for the entire heating season, then there is a risk of defrosting and damage to the pipes and batteries of the system.

Features of diesel boiler maintenance

Even with a correctly configured burner, during operation, soot and ash settle on the inner surface of the combustion chamber and the surface of the heat exchanger. Even a small amount of these deposits significantly reduces the intensity of heat transfer, so a layer of soot 2 mm thick reduces the efficiency of the installation by 10 - 12%. To prevent this, it is necessary to regularly clean the combustion chamber, heat exchanger and chimney pipe.

In addition, special attention should be paid to adjusting the burner, since the completeness of fuel combustion and, as a consequence, the amount of incomplete combustion products deposited on the walls depends on the correct ratio of fuel and oxygen in the combustible mixture.

To ensure maximum performance, it is also important to promptly flush or replace the nozzle that atomizes the air-fuel mixture. The use of high-quality fuel can significantly reduce soot and ash deposits on the walls of the heat exchanger and combustion chamber.

Timely cleaning of the device and proper operation will extend the life of the diesel boiler and ensure efficient operation of the heating system.

Double-circuit gas boilers

Double-circuit boilers have two basic functions:

• House heating.
• Supply of hot water for domestic needs.

All other features are considered additional, contributing to a more successful and efficient performance of the main tasks. A special feature of this type of boiler is the need to operate throughout the year.

Single-circuit structures are stopped for the summer, which makes it possible to increase the service life of components and parts. Double-circuit units have to be operated in constant mode, turning off only the supply of coolant to the heating system.

This increases the load on the parts and components of the unit, reduces the life of the most loaded areas of the boiler.

As a rule, for such designs the power level is limited to 40-50 kW; more efficient units are already equipped with built-in storage devices or external boilers.

In terms of design, dual-circuit models are a basic option with an added secondary heat exchanger. However, there are other types of boilers that can demonstrate more stable and high performance.

These include:

• Designs with a combined heat exchanger. They provide more stable DHW heating, high performance and quick response to requests.
• Condensation models. These are boilers with the function of preheating the coolant using thermal energy from the condensation of water vapor from flue gases. Manufacturers claim an efficiency of 107-109% for them, which is completely absurd from a physics point of view. At the same time, condensing units are capable of working only with low-temperature systems. Under normal conditions, they lose additional capabilities and function as convection structures.

Double-circuit gas boilers are distinguished according to certain characteristics.

By installation method:

• Wall mounted . For hanging installation, strong load-bearing walls are required. The dimensions and weight of such units are limited by permissible load conditions.
• Floor-standing . They can be installed directly on the floor, which expands the capabilities of boilers and allows them to be equipped with massive units of increased power and productivity.

By type of heat transfer:

• Convection . The coolant is heated by a gas burner.
• Condensation . A two-stage heating scheme is used, where the first stage is the heating of the return flow in the condensation chamber, and the second is the usual preparation process in the primary heat exchanger. For the process to proceed correctly, it is necessary to provide appropriate conditions, which is only possible in the southern regions.

By heat exchanger type:

• Separate . The heating of the coolant is carried out by the primary unit, and the secondary heat exchanger (usually plate type) is responsible for preparing hot water.
• Combined (bithermic) . It is a coil made of a pipe of a specific cross-section, where two streams can flow simultaneously without mixing. Allows you to increase DHW productivity, but is difficult to clean from lime deposits.

By type of combustion chamber:

• Atmospheric (open) . The traditional way of boiler operation, where smoke is removed naturally through a standard chimney, and air is taken directly from the room.
• Turbocharged (closed) . Air is taken from the outside using a coaxial chimney (pipe-in-pipe design). The turbocharger fan provides fresh flow. It also displaces flue gases, providing a stable and adjustable smoke removal mode.

Benefits of a diesel boiler for your home

Diesel boilers for heating and hot water systems in private housing construction have a number of advantages that fully compensate for expensive diesel fuel. The most important advantages are an efficiency of 85% and the ability to automate the combustion process. The user can independently install a recreation center at home without obtaining permits from the gas inspectorate and mandatory training and passing operating exams.

The main advantages of a diesel boiler for the home:

• fast execution of installation and construction work;
• affordable fuel supply even for remote areas;
• installation of smoke exhaust through the building wall;
• automatic combustion mode in accordance with the outside temperature;
• high level of protection, complete shutdown of the diesel heating boiler in the absence of water and torch breakage; acceptable prices.

However, this system also has disadvantages that can be technically eliminated, for example, noise during operation and the smell of diesel fuel, which is eliminated when diesel boiler systems are placed in separate buildings. The next disadvantage of DC is its energy dependence, therefore, in regions with a low level of power grid reliability, the installation of a backup power source is required.

How much fuel does it consume per month?

Fuel consumption for a diesel boiler for heating needs (Рт) is related to the boiler power and is indicated in the passport. It can be obtained by dividing the DC power in kW by 10, the result is obtained in kg, the calculation is applicable for heating cold equipment during start-up.

In stable operating mode, this figure corresponds to 30-50% and depends on the level of thermal insulation of the building. The required power (Mk) is proportional to the area in the ratio: 10 kW per 100 m2.

To determine the fuel consumption of a diesel boiler for a month or season, simple calculations are performed:

RT = Mk X 0.1. For a house area of ​​100 m2, the minimum power should be: 0.1X100= 10 kW. Next, the hourly rate is calculated: 0.1X10 = 1 kg of diesel fuel. Daily consumption: 1X24=24 kg.

It corresponds to the minimum outdoor temperature in winter, which depends on the installation area and is specified in SNiP 23-01-99 “Building climatology”.

If the heating season is 200 days a year, for preliminary calculations we can assume that half of this period the household will operate at full load, and 100 days at half load, then diesel fuel consumption for the entire season: (100X24) + (100X12) = 3600 kg. Consumption for the winter month with minimum outside temperature: 100X24=240 kg. Consumption for the spring month: 100X12=120 kg.

These are average costs; they do not indicate a number of parameters: the degree of insulation, the estimated temperature inside the room, the load on the hot water supply, the design of the heating unit.
