When building a country house, the organization of heating becomes an important issue. In the absence of the gas pipeline to solve the problem will help diesel heating boiler for a private house.
Features of the use of liquid fuel boilers
Diesel boiler installed for heating a private house has many advantages in comparison with other heating systems. The obvious advantages include the following factors:
-
the boiler operation process is automated, it is regulated based on the temperature of the coolant;
-
high efficiency, amounting to 85 -95%;
-
direct connection of diesel equipment does not require complex coordination with various authorities;
-
installation of diesel equipment is fast;
-
the supply of fuel for the boiler is not difficult;
-
smoke removal can be arranged through the wall;
-
affordable price equipment.
The disadvantages include:
-
high fuel consumption and a significant price for it;
-
for the constant supply of diesel fuel, a storage system should be organized and connected to the boiler;
-
volatility;
-
the need to place the boiler in the boiler room allocated a separate room;
-
the need for a backup power supply.
Equipment classification
Depending from the requirements for equipment, a specific boiler model is selected. Characteristics that are important when choosing a heating boiler:
-
power;
-
type of combustion;
-
material manufacturing heat exchanger;
-
fuel consumption;
-
additional possibility of heating water.

Power
The economy of diesel fuel consumption and the efficiency of the unit operation depend on the power consumption. The generally accepted unit of power measurement is kilowatt. This characteristic is necessarily reflected in the documentation attached to the boiler.
Selection of a model for power should be performed based on the area of the heated room of the house. The calculation of the required power is quite simple: summarize the area of all the premises, and the resulting amount should be divided by 10. This formula determines the capacity of the boiler for a house located in a temperate climate.
This method of calculation is suitable for rooms in which the ceiling height is not more than 3 m. If the building is located in an area with a cold climate, then the calculated power of the unit must be increased in the range from 20 to 30%.
Determination of fuel consumption
Diesel heating of a private house requires significant consumption diesel fuel. It depends on the power of the boiler equipment. It is possible to calculate the amount of fuel by the formula: the power of the boiler is divided by 10. The resulting quotient is the hourly fuel consumption (in kilograms) during heating.
In the temperature maintenance mode, fuel consumption is significantly reduced. How economically diesel fuel will be consumed at the same time depends on the quality of the insulation of the building. With a weak - a decrease in consumption will occur by a third, with good - up to 70%. The average fuel consumption for a private house is usually from 500 to 900 grams.
Boilers for heating and heating
Diesel boilers can serve not only to heat a house, but also to heat water. Devices that combine both of these functions are called dual circuit.
If such an option is needed, the calculated power should be increased by one fifth. Such a factor should be taken into account immediately. Otherwise, the power of the diesel boiler may not be enough for heating water and for heating.
Cast iron
The heat exchanger made of cast iron has a higher corrosion resistance compared to steel. But at the same time it can crack from the temperature drop.Cast iron is heavier than steel, its price is higher.
Steel
The steel body is lighter and cheaper than cast iron, it is resistant to temperature changes, but is susceptible to corrosion. Stainless steel has the best performance. But such a boiler will cost more.

Principle of heating
According to the principle of heating, diesel fuel boilers are of two types:
-
condensing;
-
traditional.
Condensation is more efficient, because it uses energy from condensate. This makes it more economical to use fuel. The price for this type of boiler is higher.
Organization of a boiler room
When installing diesel heating, it is necessary to provide for the organization of a boiler room in a separate room. This is necessary because of the noise and odor created during the operation of the boiler.
Room parameters for a boiler room
Size of a boiler room should allow to install the boiler itself and the capacity for diesel fuel. The space reserved for the boiler room should be at least 4 m², the ceiling height should be from 220 cm. The door reception should be from 80 cm and windows should be available.
A prerequisite is the organization of the boiler body grounding and automatic connection to the power grid. In case of unstable power supply, it is desirable to provide an alternative option for power supply.
Tank for diesel fuel
The capacity for diesel fuel in the boiler room should be no more than 0.8 m³. For these purposes, most often used special tanks, made of resistant to the aggressive effects of polymer fluids.
The fuel tank must have the following elements:
-
float level gauge;
-
valve for evaporating fuel;
-
mounting fittings;
-
a fuel pickup that allows you to take fuel not from the bottom, where sediment forms.
For information! If a filter is not provided in the boiler burner, it should be on the tank.
Additional tanks with fuel
Capacity of the installed volume for heating a country house during the heating season is not enough. The problem is solved by an external tank. It can be one capacity or several connected to each other. The most commonly chosen volume is from 2,000 to 4,000 liters.
Material manufacturing tanks:
-
metal;
-
plastic;
-
fiberglass.

General recommendations for choosing
Diesel heating of a country house has a relatively high price due to the cost of diesel fuel. And when selecting equipment, the following principles should be followed:
-
When planning further transfer of heating to gas
If in the future it is planned to switch to gas heating, it is better to purchase such a boiler model, which is designed to replace the burner.
-
Street tanks
For tanks installed outside, insulation should be provided during the cold season. In the absence of good insulation of the pipeline and tank, the viscosity of the fuel increases, which disrupts its flow through the pipeline, increases the load on the pump and reduces the efficiency of the boiler.
-
Chimney Organization
The chimney for diesel-fired boilers does not require sophisticated equipment. This is due to the almost complete combustion of diesel fuel, as well as the relatively low temperature of the released gas. The most commonly used coaxial chimney, which has built-in ventilation and output through the wall.
Important! The diameter of the chimney should not be less than at the exit from the boiler.
-
Equipment Prevention
Periodic maintenance should be provided for long-term good operation of the equipment. At least once a season, equipment should be prevented with elements cleaned, replacement of worn parts, and repair of individual engineering components.
Cleaning elements will allow the boiler to serve smoothly and with greater efficiency. With the accumulation of soot with a layer of 10 mm, the capacity of the unit can decrease by one third with an increase in the consumption of diesel fuel.

Boiler prices in the capital
There is a wide choice on the modern market the coppers using diesel fuel for work. The price of diesel boilers in Moscow starts from 28 000 - 30 000 rubles. For this amount you can buy a reliable unit with a capacity of 16 kW and a sufficiently high efficiency (more than 90%). Electronic control of such a floor installation with a steel heat exchanger can have a remote control, overheat protection, autodiagnostics and freeze prevention mode.

Conclusion
Automating the operation of the boiler on diesel does not pose any difficulty with adjustment if the installation was done professionally. Equipping a private house with a diesel heating system will make it easy to create comfortable temperature conditions in the room.
