The choice of energy is the most important stage in the design of a heating system. Traditionally, solid fuels (firewood, coal) and natural gas were used for this. Recently, diesel fuel systems have become widespread. In this case, it is important to take into account the main parameters, we make the heating of a private house with diesel fuel with our own hands: boilers, flow, schemes, temperature operation. First you need to familiarize yourself with the specifics of the boiler design.
Features of the arrangement of heating in diesel fuel
The operation of a heating device using diesel fuel is almost identical to the operation of a car engine. All autonomous heating boilers for diesel fuel must have a special burner. It is also a source of thermal energy.
Structurally, the burner consists of the following elements:
- Supply line. Ensures the flow of fuel into the combustion zone;
- Turbine. Designed to create pressure;
- The nozzle is used to spray diesel fuel, as a result of this a combustible mixture is formed;
- Devices for power control and flame monitoring.
Many heating boilers in diesel fuel have a crankcase, where waste from the combustion process flows. This is a specificity of diesel fuel, since the level of mineral precipitation after its combustion is several orders of magnitude higher than that of ordinary gas.
It is noteworthy that you can use a conventional boiler. For this, the dimensions of the door of the combustion chamber must correspond to the mounting dimensions of the burner. Thus, heating in diesel fuel can be done on the basis of an existing system. For this, it is necessary to carry out a certain modernization.
Storage of diesel fuel: an overview of options
The main task for the owner of the house with heating in diesel fuel is the organization of fuel storage. The operation of a diesel boiler involves a large consumption of energy. Therefore, it is necessary to provide appropriate conditions for the safe maintenance of the optimal fuel volume. To do this, you can use two types of tanks - open and closed installation.
Surface plastic barrels
They are structures made of polyethylene or PVC. The maximum recommended amount for heating on diesel fuel with your own hands is up to 1000 liters. Be sure to be equipped 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 suburban cottages or houses with a relatively small area.
Underground tanks
Designed to store up to 20 thousand liters of fuel. Until recently, they were made only of galvanized iron. But the appearance of chemically stable plastic made it possible to make lighter and more affordable designs.
A 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 be not only effective, but also safe. Unlike small tanks, the underground storage is equipped with a pumping station.
In addition to level sensors, fuel leak detectors must be present. To fill the barrel, diesel fuel for heating is required, carried out by specialized companies selling fuel and lubricants.
The choice of a burner in 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. But in addition to this, it is necessary to know the main 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 is necessarily taken into account for heating on diesel fuel made by yourself. But this rule applies only with good thermal insulation of the house. To ensure power reserve, it is necessary to add 15-20% 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.
- Overall dimensions of a torch. The ability to install the device in the boiler depends on this;
- Mode of operation. Single-stage models operate only at constant power. For two-stage it is possible to adjust the degree of heating - maximum and average. Modular are optimal, since the options for heating the house with diesel fuel are different for them - from the minimum value to 100% heating of the coolant;
- Price. The most popular LAMBORGHINI burners have a cost ranging from 20 to 40 thousand rubles.
It is also important to pay attention to the possibility of switching from diesel fuel to used engine oil. To do this, the design should include the function of replacing the nozzle model with a large nozzle diameter.
Calculation of diesel fuel consumption by a 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 will require an average of 1 kg of fuel, i.e. when operating in maximum mode, 24 kW of the boiler per hour will consume about 2.4 kg of diesel fuel.
Therefore, you need to carefully select the temperature regime for heating the coolant and, as a result, the degree of heating of an autonomous heating boiler in diesel fuel. If the equipment will operate 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 inadmissible luxury. To reduce these costs, you can take the following measures:
- Purchasing a modular burner. It is able to precisely control the level of fuel supply for optimal heating of the coolant;
- Low temperature selection. This helps not only to reduce the consumption of diesel fuel, but also allows you to create an effective system of water floor heating;
- Buy radiators with maximum heat dissipation. For them, a solar heating boiler will consume less energy to compensate for heat losses due to the passage of heat through the radiator material. It is best to install bimetal models.
Also important is the frequency of diesel fuel delivery for heating. It is recommended to install a tank, the volume of which is enough for the entire heating season. In our case, subject to 12 hours of system operation, this will be 1.2 * 12 * 90 = 1296 liters.
Experts advise purchasing a tank with a margin of 1,500 liters. In this case, diesel fuel for the heating system can be delivered once a year before the heating season.
Overview of heating boilers in diesel fuel
For more efficient operation of heating in diesel fuel, you can purchase a special boiler. Such models are characterized by increased efficiency indicators, since their design, and in particular the heat exchanger, are designed to operate on liquid fuel.
Installing the burner in a conventional solid fuel boiler will not always create the desired level of heating medium. Therefore, it is recommended to purchase factory models.
Kiturami boilers
One of the most popular manufacturers of heating boilers working on diesel fuel. This South Korean company specializes in the production of heating equipment. The most popular models currently are:
- TURBO-17 - a double-circuit boiler with a rated power of 19.8 kW. DHW performance for it is 7.1 l / min. Cost - 39 thousand rubles;
- TURBO-30U. The most powerful model in the product line. Her work makes it possible to provide heat to the house up to 250 m². Cost - 57 thousand rubles.
All these models have floor mounting, are characterized by simple installation, as well as the ability to install a coaxial chimney.
Fondital boilers
The undeniable quality of the Italian brand is confirmed by the demand of customers. The company emphasized the optimal configuration, which positively affected the functionality:
- Capri BTF 33. Net power - 33 kW. The material for manufacturing the heat exchanger and the casing is cast iron, which positively affects the service life. An advantage is the 130 liter integrated expansion tank. Cost - 74 thousand rubles;
- CAPRI BTF 23. Completely similar to the 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 do the heating of a private house with diesel fuel yourself: boilers, flow, schemes and other useful data.
DIY heating installation on diesel fuel
The installation of heating boilers operating on diesel fuel should begin with the drawing up of a diagram. It should include the location of the device in the house (boiler room), the wiring of pipes for supplying coolant to radiators and system protection elements.
In this case, the following factors must be taken into account:
- The place of storage of fuel tanks should 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 in galvanized iron, since the level of soot when heating the house with diesel fuel will be an order of magnitude higher than that of solid fuel or gas.
If heating is done on diesel fuel with your own hands - you need to be very careful when choosing a burner or boiler. Their rated power should correspond to the calculated parameters of the entire system.
When analyzing 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 at the maximum distance from the living quarters. The ideal option is the arrangement of a separate boiler room.
