Heating coppers diesel for the house. Heating a country house with a diesel boiler

07.06.2021

Designing a private house at the very first stages involves the choice of a heating system. It is made up of many factors that need to be taken into account. Heating a house with a diesel boiler is beneficial, for example, when there is no gas supply on the site and is not even planned in the near future. This heating option is the most acceptable in many respects. Let's consider in more detail.

Diesel boilers for heating

Advantages

Let's start right away by considering the winning points (those that are not very good, we will discuss later) characterizing heating country house diesel fuel. This question is relevant for many owners of private housing, because diesel fuel is not cheap, frankly, a lot of it is required for the heating season.

The coefficient of performance (COP) of the discussed equipment is high, it reaches 95% under the following conditions:

correct installation of the boiler;
furnace devices according to all rules and regulations;
high-quality insulation of the house;
installation of double-glazed windows;
proper storage of fuel supplies;
use of high-quality fuel;
timely maintenance;
competent choice of equipment capacity, manufacturer, model.

Efficiency can reach up to 98% when using a condensing type of boiler, but more on that later.

Wide Range model range, manufacturers, power characteristics, etc.
Economical consumption of electrical energy.
Environmental friendliness, which is a fairly current trend in modern European society. When burned, almost no harmful substances and gases are formed.
High level of safety compared to gas boilers.
Autonomous, automatic operation that does not require constant human intervention.
Inertia is not typical for diesel boilers (unlike solid fuel counterparts). Performance drops instantly.
Liquid fuels take up much less storage space than solid fuels (peat, wood, coal).
The ability to use used engine oils, which are cheaper. At the same time, the issue of disposal of waste material, which is completely burned in a diesel unit, is solved. Again - a reference to environmental friendliness.

disadvantages

Now consider the points that hold back buyers in their desire to purchase a diesel heating device:

In the first place is the high price of fuel material. This makes the equipment expensive to use. It is justified only by the absence next to land plot gas line. Bringing gas communications from afar will be an even more expensive undertaking.
Diesel oil contains impurities that clog the nozzle and reduce pump performance. At the same time, the installed cleaning filters are quickly clogged with paraffin. Without timely maintenance, the boiler will not operate at full capacity with the same amount of fuel.
The need for specially equipped storage for fuel.
The need for a stable power supply. If situations with a power outage are expected, it is better to get a stabilizer.
A strong smell, noise require the equipment of a separate isolated room, building.
thickening heating material under the influence of temperatures below + 5⁰ C, which makes the pump work in enhanced mode.

How to choose a boiler for heating a private house?

If, nevertheless, the choice fell on a diesel unit, its purchase should be based on factors:

Burner type. The best option is a replaceable burner, powered by a diesel, and if necessary, from a gas source. If there is a burner heating system, fuel consumption will be significantly reduced.
Productive power of the boiler. It is calculated taking into account the volume of the room, the amount of diesel fuel used. As a rule, 1 kWh of energy is consumed per 10 m². For housing with an area of 150 m², it is necessary to purchase a boiler with a capacity of at least 15 kW, and preferably a little more, so that there is a power reserve for extreme cold.
The number of contours. You need to decide how the water will be heated. Boilers are produced with already built-in boilers, or, for example, with a second circuit for an indirect water heater purchased separately.
Furnace material. The steel body of the firebox is more economical, but not as wear-resistant and durable. Cast iron firebox designed for 50 years of operation, resistant to sulfur-containing condensate, corrosion. At the same time, it is prone to cracking from temperature changes.
Type of fuel material. The best option, of course, is to work on all types of fuel (diesel oil, used oil, gas). But this option will be a very expensive purchase.

How does a diesel boiler work for heating a private house?

Heating equipment with diesel fuel is a combination of devices: the boiler itself, the automatic control system, the fuel unit.

The boiler consists of:

Frame. Produced with combustion chambers:

open type(communicated with the space of the air intake room, requires installation supply ventilation in the furnace);
closed type(the chamber is isolated, the air is supplied under pressure).

Electric ignition block. Generates a spark in the burner to ignite the supplied fuel.
Burner. Depending on the method of air supply, there are:

supercharged(air is supplied by a turbine);
fan(supplied by fan).

Replaceable burners are installed in combined boilers, they require operation from different kind fuels such as diesel, gas.

Combined boiler scheme

The automatic control system is divided into blocks:

working unit(responsible for maintaining a certain temperature of the carrier, turning the unit on and off as necessary);
emergency block(security control, emergency stop of equipment during an emergency).

The fuel assembly includes:

fuel tank;
fuel pump(fuel supply to the burner from the tank);
chimney (takes combustion products outside).

Scheme of functioning of a diesel boiler

Equipment for heating a private house works as follows:

The fuel pump and the air supply system to the combustion chamber are activated.
The pump pumps fuel from the storage tank into the combustion chamber. Here the fuel material is filtered and heated.
The pressure of the nozzles increases to 10-16 atmospheres. This is enough to spray the fuel to a state of suspension.
The electric ignition is switched on.
Atomized fuel mixes with forced air, ignites from an electric spark.
Released during combustion thermal energy enters the heat exchanger, heats the coolant.
The coolant circulates through the heating devices, heating the rooms of the house.
If the condensing boiler is in operation, the thermal energy of the emitted gases is also used for heating.
The products of combustion of fuel are removed by the chimney outside the house.

Types of diesel boilers for heating a private house

Diesel heating equipment differs in several ways. One of them is the adjustment of the power of the burners. In this case, the boilers are:

Single-stage (power of the burners is not regulated, the heating temperature is constant).
Two-stage (burners operate in two positions).
Modulated (wide range of burner performance adjustment).

In addition to space heating, a diesel heating boiler for a private house often performs a water heating function. This is very convenient and saves a lot on electricity. According to this indicator, heating systems are divided into:

Single-circuit. They perform only the function of heating the room.
Double-circuit. A double-circuit diesel boiler for heating a country house combines room heating (primary circuit) and running water heating (second circuit). At the same time, there is a decrease in space heating by 20%.
Double-circuit + built-in water heater. The second circuit is designed to heat water inside the boiler. Thus, you can significantly reduce the cost of electricity in winter.

Double-circuit diesel boiler

Installation rules

It is best to call specialists to install the equipment, who will make the connection professionally. However, the installation of a diesel heating boiler can be done independently. Its installation does not require mandatory special permission, as is the case with gas equipment. But there are separate requirements for installation, as well as the arrangement of the furnace room:

To install a heating boiler, it is necessary to provide a separate building. If this is not possible, at least a separate technical room, for example, in the basement of the house. The main condition for this is that there must be a separate exit to the outside.
Ceilings in the equipment room are provided for at least 2.5 m.
The volume of a technical room or a separate building should not be less than 15 m².
Experts strongly recommend installing fuel filters to extend the life of the equipment.
For boilers with a power of 350 kV, a separate power line should be drawn from the general machine.
It is recommended to install away from doors and windows.
Furnace wall cladding with non-combustible finishing materials.

Fuel storage

An important issue when purchasing diesel equipment for home heating is the way the fuel is stored. You can use two options.

The first involves the storage of flammable liquid inside the boiler room. Moreover, the maximum volume that is allowed for storage is 800 liters. This is not enough, it will not be enough for the entire heating season, especially for regions with a long period of cold weather.

Fuel tank wiring diagram

Therefore, the second variant of fuel storage using an external tank (4-10 tons) is still preferable. It is installed on the surface, or dug into the ground. It is best to place it at a depth where the layer of earth does not freeze through, so that diesel fuel does not thicken from low temperatures. environment. Additionally, the container is insulated, as well as the pipeline for supplying fuel to the furnace.

It is preferable to choose stainless steel fuel tanks.

When it is not possible to conduct gas communications for heating a country house, a diesel boiler can be a good alternative. Heating a private house with diesel fuel costs a lot of money, but it is much more economical than the option using electrical equipment.

Piping schemes for solid fuel boilers. Kinds. Operating principle

Structurally, diesel boilers are almost fundamentally different only in their burners. Many manufacturers produce, which can work on diesel fuel and on natural gas. When changing fuel on such boilers, it is necessary to change the burners. If the burner is built-in, and the boiler can only work on diesel fuel, the cost of such a boiler is lower than that of a universal one.

Main structural elements diesel boiler:

diesel burner;
fuel filter;
fuel pump;
external control panel;
coolant and temperature control sensors.

The fuel entering the burner is mixed with air and sprayed by the fan in the combustion chamber, where it ignites and burns, heating the chamber walls and the coolant. The gases formed as a result of combustion are removed through the chimney.

What is the fuel consumption of a diesel boiler

The ratio of boiler power to fuel consumption is very simple:

P \u003d M / 10, where

M - boiler power, kW;

P - diesel fuel consumption, kg / hour.

When heating with a diesel boiler and providing a house with an area of 200 sq.m. hot water in Russian conditions, the heating season will require about 2 tons of diesel fuel, which is 92 thousand rubles (with a fuel price of 46 rubles / liter). For example, at , you will spend 10 times less.

What to look for when buying a diesel boiler

Diesel boilers are fundamentally no different, although their efficiency and cost may be different. When choosing a diesel boiler for heating a private house, consider:

1. Heat exchanger material

Heat exchangers in diesel boilers are made of cast iron and steel. Steel boilers are more economical, stronger and lighter, while cast iron ones last longer. Experts recommend buying cast-iron boilers for private houses, and steel boilers for offices and administrative buildings.

2. The principle of heat generation

IN condensing boilers, unlike the usual ones, in addition to the traditional heating of the walls of the combustion chamber, heated condensate is additionally used. Such boilers are more expensive, but their efficiency and productivity are higher than usual.

3. Number of circuits

Single-circuit boilers, supplying heated water to the heating system, are used only for heating the house. Double-circuit boilers, in addition to heating, they are also used to heat water. The cost of a double-circuit boiler is higher, so the feasibility of installing it must be determined individually. If the required boiler output for heating significantly exceeds the need for hot water. then it would be more correct to purchase a single-circuit boiler and a boiler for heating water.

4. Liquid boiler maintenance

A feature of the operation of diesel boilers is the increased formation of soot and ash. It is necessary to remove combustion products in time, since their accumulation leads to increased fuel consumption. So, with a soot layer thickness of 2 mm, the consumption of diesel fuel increases by 8-10%. Maintenance of the boiler consists in cleaning the burner nozzle and the divider from carbon deposits. The frequency of cleaning depends on the quality of the fuel - good fuel gives a minimum of soot. The boiler is checked once a year in preparation for the heating season, but it is better to do this every six months. The work is carried out by a specialist. In addition to cleaning, the master changes the fuel filter, individual parts of the burner and adjusts its operating mode. Regular maintenance of the boiler burner increases its service life.

So which diesel boiler to choose

The Russian heating equipment market offers diesel boilers from the following well-known global manufacturers:

Wolf (Germany);
De Dietrich (France);
Protherm (Slovakia);
Ferroli (Italy);
Viessmann (Germany);
Vaillant (Germany);
Dakon (Czech Republic);
Buderus (Germany).
Roca (Spain).

Prices for diesel boilers depend on the power, manufacturer and configuration. According to consumer reviews, all of the listed brands of boilers are reliable, economical, with a high level of automation and a long service life.

conclusions

When choosing a diesel boiler, you need to determine required power, which is installed (with a small margin) at a flow rate of 1 kW per 10 sq.m of heating surface area.
If more hot water is needed, then a small power reserve should also be provided for the double-circuit boiler.
When choosing the type of boiler material, keep in mind that a steel boiler will last no more than 15 years, and a cast-iron boiler - at least 50. Otherwise, when choosing a diesel boiler, you should rely on your own preferences and capabilities.

A diesel boiler for residential heating is an ideal choice for homes located far from gas mains or with a weak electrical network. Such an acquisition will provide heating system rooms in the most severe frosts, which will create a comfortable atmosphere in your home.

What he really is?

It is a kind of floor structure, the base of which is made of cast iron or steel, which allows not only to supply heat through the pipe system, but also to heat the room through heat transfer from the heated walls of the boiler.

Modern models have a special outer coating that provides protection against overheating - this is very convenient for families with children, because even if they accidentally touch the wall of the boiler, the kids will not get burned.

Such a boiler is equipped with a fan burner, which supplies and regulates the air flow supplied to the internal combustion chamber. They also distribute liquid fuel supplied to the chamber by means of a fuel pump.

The heating system is based on mixing fuel and air flows, which leads to the ignition of the first in the combustion chamber. Regular addition of the required amount of fuel allows you to maintain a continuous combustion process.

The main classification is made according to the type of water heating. They are:

single-circuit - serve exclusively for heating the room;
double-circuit, equipped with a flow heater - allow you to heat the room, while heating the running water in the connected system;
double-circuit with a built-in boiler - in addition to the main heating function, they are able to supply hot water for the whole house.

Depending on the purpose for which you purchase it, you should choose a specific model.

Double-circuit products, of course, will be more expensive, but they will provide your home with hot water, but with a limited budget, it is better to stop at conventional liquid fuel boilers.

They also differ in the way they pull. There are:

boilers with natural draft - the exhaust gases are carried out through a vertical chimney;
forced draft boilers - such models have a closed firebox, and the exhaust gases generated after fuel processing are carried out through a built-in chimney.

When choosing a boiler for your home, you should decide in advance what size the product will suit you, what shape will fit best into the interior, and, of course, choosing a model in accordance with the available budget will be an important factor.

How to choose the optimal model

The acquisition of such heating device- a profitable solution, since diesel fuel models are much more economical than electric boilers. The advantage is due to the fact that most models are able to work not only on diesel fuel, but also on alternative types of fuel, such as liquefied gas.

To choose the optimal model from the numerous range of offers from leading manufacturers of heating equipment, you need to compare all the parameters.

When choosing a heating boiler, the type of burner used is considered an important indicator, so its characteristics should be given increased attention:

An important parameter is the power of the boiler. It is determined from the consumption of 1 kW for every 10 squares of the area of \u200b\u200bthe room. If the purpose of installing the boiler is not only heating, but also the supply of hot water, then it is better to choose a boiler with a little more power.

Tip: in order for the boiler to cope with all its functional duties, its power should be slightly greater than required to heat the selected room.

The main question of interest to every buyer is the fuel consumption of the selected model. It is not at all difficult to find out this parameter; fuel consumption in kilograms per hour is equal to a tenth of the power of the burner used. Depending on this indicator, you can choose a boiler whose maintenance you can afford.

The material from which the firebox is made affects the durability of the device. A steel boiler will be more economical, but will last no more than 15 years. In turn, a cast-iron product consumes more fuel, but has a service life of at least 50 years.

Remember: the best option would be to purchase a universal boiler that can run not only on diesel fuel, but also on liquefied gas, kerosene, fuel oil. This will allow not to stop the heating process in case of running out of fuel.

Advantages and disadvantages

Advantages:

Autonomy - functioning heating system does not depend on the main gas supply or electricity supply at home. The main thing is to stock up on enough fuel.
Durability - average service life of 40-50 years.
Products have a high-quality insulated housing, which ensures the safety of their use.
High efficiency - they provide a large heat transfer in a short time, so they can quickly heat even large rooms.
Additional heated burners used in modern models provide economical fuel consumption.
All boilers have an easy-to-manage control system.
Most models can run on both diesel fuel and other types of fuel.
Availability - installation does not require special permission and can be done independently.

Disadvantages:

The installation of a heating system is very expensive, because in addition to the purchase of direct equipment, it is required to purchase fuel storage tanks, purchase a certain amount of combustible material, equip a separate room, etc.
The high cost of the fuel used will make it irrational to use for heating small rooms.
A diesel boiler requires constant maintenance and periodic cleaning, otherwise the soot produced after fuel combustion can clog the mechanism and interfere with the normal operation of the device.
Boilers equipped with an automatic control system are powered by the mains, therefore, in the event of a power failure, the use of the automation function will become impossible.

A diesel heating boiler is ideal for a country cottage or other facility that is not connected to a central gas supply system. The use of such boilers will allow you to create a completely independent system that can automatically maintain the required temperature in the premises, as well as provide the building with hot water.

Types of diesel boilers

At the moment, diesel boilers are comparable in popularity with gas boilers. Some models of such equipment can operate on two types of fuel, which makes them truly versatile. For the most part, diesel boilers for heating are floor-mounted due to their large mass, however, there are also wall-mounted options. The main advantage of this equipment is its good heat capacity, which makes it possible to efficiently use the heat obtained from fuel combustion. Diesel boilers have a very large range of output heat output - from 10 to 3600 kW.

The price of diesel boilers for heating a private house or other object will depend on the power of a particular model and the automation system used.

How to choose a diesel heating boiler

There are a lot of criteria for choosing a diesel boiler for heating a private house, so if in doubt, it is better to immediately contact a professional who is guaranteed to select the optimal equipment for you.

The main criteria for distinguishing boilers for diesel heating:

Heat generation method. Boilers are classified into traditional and condensing. The latter are more productive and economical due to the use of the heat of the resulting condensate and, accordingly, a decrease in diesel fuel consumption.
Manufacturing material. The main materials of a diesel boiler are cast iron and steel. Cast iron boilers are durable, easy to maintain and repair, but heavy and fragile. Steel have less weight, but also a shorter service life.
Functions. Diesel boilers can be used both exclusively for heating houses (single-circuit), and for heating and simultaneous heating of running water (double-circuit).
By type of installation. Diesel fuel boilers are wall-mounted and floor options. The latter are more affordable and popular, since wall-mounted ones require the use of higher quality fuel.

How to order a diesel boiler

Before ordering heating equipment, read reviews on the operation of specific models and watch a video that will allow you to understand the principle of their operation and design features. If you have any questions - contact our specialists by phone and get detailed answers to them.

Usually, most areas located far outside the city, due to some circumstances, do not provide central gas supply for a long time. Use electrical types heating equipment is a very costly business. Melting the house with logs or firewood is also not an option, it is tiring. It is precisely for such cases that diesel heating boilers are needed, the prices of which are not so high.

Liquid fuel (diesel) heating boilers - maximum comfort away from civilization

The main purpose of diesel boilers

The main scope of their application is rather large (by area) premises, ranging from 100 square meters. Of course, most often diesel heating boilers are purchased for - impressive in size - industrial or semi-industrial buildings (factory workshops, warehouses, country hotels), but there are also diesel boilers for heating a house that have not too high power and, accordingly, a lower price ( quite suitable for most buyers).

Diesel boilers are easy to operate

Almost any modern diesel fuel boiler is very easy to use: in fact, you first need to fill the fuel tank, after which you just turn it on. That's all! The principle works: "turn on and forget". The system functions completely automatically, and the user will only adjust the temperature indicators that are necessary for himself.

It is worth noting here that not even an industrial (i.e., highly powerful) version of the design, but simply an ordinary diesel heating boiler for a private house is capable of heating your home in a matter of minutes, which is very useful for a winter evening when all the family gathers at home after work.

What to consider when choosing a diesel boiler

1) Heat exchanger material. There are 2 options: cast iron or steel.
