The choice of energy carrier is the most important stage in the design of a heating system. Traditionally, solid fuels (wood, coal) and natural gas have been used for this. Recently, diesel-fueled systems have become widespread. At the same time, it is important to take into account the basic parameters, we do the heating of a private house with diesel fuel with our own hands: boilers, consumption, temperature regimes of operation. First you need to familiarize yourself with the specifics of the boiler design.

Features of the arrangement of heating on diesel fuel
The operation of a diesel heating device is almost completely identical to that of a car engine. All autonomous diesel heating boilers must have a special burner. It is also a source of thermal energy.
Structurally, the burner consists of the following elements:
- Supply line. Provides fuel supply to the combustion zone;
- Turbine. Designed to create pressure;
- The nozzle is used to spray diesel fuel, as a result of which a combustible mixture is formed;
- Devices for power regulation and control over the state of the flame.
Many diesel heating boilers have a crankcase where waste from the combustion process flows down. This is a specific feature of diesel fuel, since the level of mineral precipitation after combustion is several orders of magnitude higher than that of conventional gas.
It is noteworthy that an ordinary boiler can be used. For this, the dimensions of the combustion chamber door must correspond to the installation dimensions of the burner. Thus, heating with diesel fuel can be made on the basis of an existing system. For this, it is necessary to carry out a certain modernization.
Diesel fuel storage: an overview of options
The main task for the owner of a house with diesel heating is the organization of fuel storage. The operation of a diesel boiler implies a large consumption of energy resources. Therefore, it is necessary to ensure the appropriate conditions for the safe maintenance of the optimal amount of fuel. For this, you can use two types of containers - open and closed installation.
Surface plastic drums
They are structures made of polyethylene or PVC. The maximum recommended volume for heating with diesel fuel with your own hands is up to 1000 liters. They must be completed with a float level, a sealed cover and a fuel intake.
Such containers are used to store a small amount of fuel. Most often - in country cottages or houses with a relatively small area.
Underground reservoirs
Designed to store up to 20 thousand liters of fuel. Until recently, they were made only of galvanized iron. But the advent of chemically resistant plastic has made it possible to make structures that are lighter and more affordable.
The plastic barrel is installed in a special pit at a distance of at least 5 meters from the foundation of the building. In this way, heating a private house with diesel fuel will not only be effective, but also safe. Unlike small tanks, underground storage is equipped with a pumping station.
In addition to level sensors, fuel leakage alarms must be present. To fill the barrel, the delivery of diesel fuel for heating is required, carried out by specialized companies selling fuels and lubricants.
The choice of a burner for diesel fuel
The burner is the main element of the diesel fuel heating system. Reviews will help create an objective opinion about its quality and durability of work. But besides this, you need to know the basic technical parameters of the device.
The main selection criterion is power. It directly depends on the area of heating of a private house with diesel fuel. It is recommended to use the ratio - it is necessary to generate 1 kW of thermal energy per 10 m2 of the room. Such an indicator must be taken into account for heating with self-made diesel fuel. But this rule only applies if the house is well insulated. To ensure a power reserve, 15-20% must be added to the resulting figure. But it should be remembered that this will directly affect the consumption of diesel fuel for heating the house.
In addition to this indicator, such factors are taken into account when choosing.
- Burner dimensions... The possibility of installing the device in the boiler depends on this;
- Working hours... Single stage models only operate at constant power. For two-stage, it is possible to adjust the degree of heating - maximum and average. Modular are optimal, since they have different options for heating the house with diesel fuel - from the minimum value and ending with 100% heating of the coolant;
- Price... The most popular LAMBORGHINI burners cost from 20 to 40 thousand rubles.
It is also important to pay attention to the possibility of switching from diesel to used engine oil. To do this, the design must provide for the function of replacing the nozzle of the model with a large nozzle diameter.
Calculation of the consumption of diesel fuel by the heating boiler
To calculate the consumption of diesel fuel for heating a house, you need to know the rated power of the burner. On average, to generate 10 kW of energy, an average of 1 kg of fuel is required, i.e. when operating in the maximum mode of 24 kW of the boiler, approximately 2.4 kg of diesel fuel will be consumed per hour.
Therefore, it is necessary to very carefully select the temperature mode of heating the coolant and, as a result, the degree of heating of the autonomous heating boiler on diesel fuel. If the equipment operates around the clock at maximum power, then at least 29 kg of diesel fuel will be required. Given the increased cost of fuel, this is an unaffordable luxury. To reduce these costs, you can take the following measures:
- Purchase of a modular burner... It is able to accurately regulate the fuel supply level for optimal heating of the coolant;
- Selection of low temperature operating mode... This not only helps to reduce the consumption of diesel fuel, but also allows you to create an effective water floor heating system;
- Buy radiators with maximum heat dissipation... For them, a heating boiler on a solarium will consume less energy to compensate for heat losses for the passage of heat through the material of the radiator. It is best to install bimetallic models.
Also, the frequency of delivery of diesel fuel for heating plays an important role. It is recommended to install a container, the volume of which will be sufficient for the entire heating season. In our case, assuming 12 hours of operation of the system, this will be 1.2 * 12 * 90 = 1296 liters.
Experts advise purchasing a container with a margin of 1500 liters. In this case, the delivery of diesel fuel for the heating system can be carried out once a year before the heating season.
Overview of diesel heating boilers
For more efficient operation of heating with diesel fuel, you can purchase a special boiler. Such models are distinguished by increased efficiency rates, since their design, and in particular the heat exchanger, is designed to operate on liquid fuel.
Installing a burner in a conventional solid fuel boiler will not always create the desired level of heating of the coolant. Therefore, it is recommended to purchase factory models.
Kiturami boilers
One of the most popular manufacturers of diesel heating boilers. This South Korean company specializes in the production of heating equipment. The most popular models currently are:
- TURBO-17 - double-circuit boiler with a rated power of 19.8 kW. The DHW capacity for it is 7.1 l / min. Cost - 39 thousand rubles;
- TURBO-30U... The most powerful model in the product line. Its work makes it possible to provide a house with heat up to 250 m². Cost - 57 thousand rubles.
All these models are floor-mounted, characterized by simple installation, as well as the possibility of installing a coaxial chimney.
Fondital boilers
The indisputable quality of the Italian brand is confirmed by the demand of buyers. The company focused on the optimal configuration, which positively affected the functionality:
- Capri BTF 33... Net power - 33 kW. The material of manufacture of the heat exchanger and the body is cast iron, which has a positive effect on the service life. The advantage is the built-in 130 l expansion tank. Cost - 74 thousand rubles;
- CAPRI BTF 23... Completely the same as above, except for power. It is 23 kW.
The only drawback of these models is the lack of a hot water circuit. However, it is successfully replaced by a capacious tank.
Another advantage of buying factory models is the ability to take information from the manufacturer on how to properly heat a private house with diesel fuel with your own hands: boilers, consumption, diagrams and other useful data.
Installation of heating on diesel fuel with your own hands
Installation of heating boilers running on diesel fuel should begin with drawing up a diagram. It should include the location of the device in the house (boiler room), piping for supplying coolant to radiators and system protection elements.
In this case, the following factors must be taken into account:
- The storage place for fuel tanks must be organized in accordance with regulatory documents. This directly affects the safety of operation;
- For houses with a large area, it is recommended to use a collector system;
- The chimney is best used from galvanized iron, since the level of soot when heating a house with diesel fuel will be an order of magnitude higher than that of solid fuel or gas.
If you do heating on diesel fuel yourself, you need to be very careful when choosing a burner or boiler. Their rated power must correspond to the calculated parameters of the entire system.
When analyzing the reviews of heating with diesel fuel, they often talk about an increased noise level. This is due to the operation of the burner fan. Therefore, it is recommended to locate the boiler as far as possible from the living quarters. The ideal option is to equip a separate boiler room.
