There are many different heating systems, but not all of them can be implemented in a private house. If financial difficulties do not allow installing and using electrical equipment, and the main gas pipeline is located far from the structure, a diesel heating boiler will be the best solution to the problem.
Advantages and disadvantages of diesel heating boilers
The diesel fuel boiler has many advantages, which is why it is in demand.
- High coefficient of performance (COP). When burning diesel fuel, a large amount of heat is released. The efficiency of diesel boilers is only slightly inferior in terms of their performance to gas boilers.
- Low power consumption. Unlike electric boilers, diesel boilers require a small amount of electricity to function. It is necessary only for the operation of control and safety automation, circulation and fuel pumps. Thanks to this feature, diesel boilers can be used in places where there are problems with the allocation of electrical power to the house.
- Low fire and explosion hazard. Diesel fuel is less dangerous than liquefied or mains gas. Installation does not require special permits, space requirements are minimal.
- Large assortment of models. Diesel fuel boilers are produced for houses with any area. It is only necessary to correctly calculate the power of the equipment. As a rule, for calculations, the formula is used: "1 kW per 10 sq. M."
The main disadvantages of the equipment:
- High operating costs. The cost of diesel fuel is in second place after electricity.
- The need for quality fuel. For year-round heating of the premises, it is necessary to take care of concluding an agreement with a supplier of high-quality diesel fuel in advance. Otherwise, the owner will have to face problems: the heat exchangers and other parts of the equipment get dirty, the burner starts to smoke, the efficiency of the equipment decreases.
The operation of diesel boilers has one feature - the release of an unpleasant odor. To purify the air, you first need to take care of the organization of a natural and forced ventilation system.
Selection criteria for a private house
The range of diesel heating boilers is large, so choosing the most suitable model is not easy. They are based on the following criteria: number of circuits, method of installation and removal of exhaust gases, power, type of fuel and cost.
If the heating system must only heat the house, it is enough to purchase a single-circuit type. If you need to heat the premises and use hot water, it is better to give preference to double-circuit heating equipment.
The power is calculated depending on the area of the heated room. When making calculations, it is important to take into account all heat conductors - wall material, floors, windows and doors. For help, you can turn to engineers or use special calculators.
Diesel boilers on the market are divided into three main price groups: cheap - Russian-made; average in price, but with good quality - made in Slovakia, Japan, Czech Republic, Spain, South Korea and Italy; expensive and high quality - made in Germany, Sweden.
Types of diesel boilers for heating
The diesel heating boiler is classified into several types according to the main characteristics: the material of the heat exchanger and the type of burner.
Burners are divided into three types:
- Modulated - the most profitable and efficient designs, their characteristic feature is the regulation of their performance from 10% to 100%, based on the required heating temperature.
- Single-stage - the least efficient, but at the same time budget models. They work continuously, therefore, to correct the temperature regime and change the power, it is necessary to completely de-energize the boiler.
- Two-stage configurations are capable of operating in two modes - 40% and 100% of the base performance. Thanks to this, it is possible to slightly save fuel consumption for heating the building.
Heat exchangers, in turn, are divided into two types:
- Steel models are easy to maintain and have an acceptable cost, at the same time, they are characterized by low resistance to corrosion and condensation.
- Cast iron heat exchangers are heavy, expensive and susceptible to overheating, but highly resistant to corrosion.
The materials used will determine the performance and efficiency of the heating system, as well as the price.
Fuel consumption calculation
To calculate the required amount of fuel, you need to know three parameters - efficiency, power and serviced area. In calculations, the following ratio is traditionally used:
- A standard burner, which runs at full capacity, burns about 24 liters of fuel in 24 hours.
- 10 kW of energy is usually enough to heat 100 sq.m.
- When 1 liter of liquid fuel is burned, about 10 kW of thermal energy is released.
For every 1 sq.m. when the burner is operating at maximum power, about 0.24 liters of fuel is needed. Knowing the average ratio, you can calculate the fuel costs for one heating season for a house with a certain area.
The diesel heating system is a worthy alternative to gas, wood-burning and even electric heating in a private house. The main task of homeowners is to thoroughly approach the choice of equipment.
