Today, the problem of heat supply in a private or country house is easily solved with the help of boiler equipment, which can be diesel, solid fuel or electric. Models of each of the listed varieties can be found on the market at affordable prices. However, maintenance of the second type of equipment involves a lot of trouble, while the electric model is too energy-intensive, so it is advisable to consider the alternative option that was mentioned above.

Which boiler to choose

The economic component of gas heating occupies a leading position. However, this type of heating can only be used when the house is connected to the mains. But liquid fuel units are structures that run on liquefied gas and other available types of resources. For example, diesel fuel is the most popular type of fuel. For its storage, you can use any container located in the immediate vicinity of the boiler. This provides a convenient organization of space, because the boiler can be installed even in the basement, and the container with diesel fuel can be removed outside it. The main advantage of such a systemstands for constant heat in the home, as well as the autonomy of devices.

Varieties by material and installation method

If you are interested in liquid fuel boilers, then you should consider their main varieties. In the store, first of all, you should pay attention to the material. Thus, devices can be implemented in cast iron and steel versions. For a country house, it is best to give preference to a cast-iron boiler. Among other things, the models can be installed on the wall or on the floor. The power of cast iron structures implies the need for installation on a plane, as well as their reliable position.

Wall models are categorical to the quality of diesel fuel, in addition, they are not leaders in sales. And the external attractive steel case is made of hardened steel, has a heat-insulating layer that provides heat retention and eliminates heating of the walls. Maintenance will be limited to the control of nozzles and burners, the first of which spray fuel. It will also be necessary to clean the chimney, and if you resort to professional help, the cost of services will be very impressive. Oil-fired boilers can also differ in the method of heat generation. Diesel devices can be condensing or classic. The most technologically advanced are the first, which will ensure the productive use of the energy of the unit.

Classification of diesel equipment

The burner in the combustion chamber is responsible for the ignition and heating of the heat exchanger. The heat is transferred to the coolant and carried through the heating system. Vapors and products of combustion are removed through the chimney, which pass through the heat exchanger and give it heat. If the boiler has an electronic control unit, it will automatically respond to problems by turning off the system during operation.

When choosing such equipment, you need to pay attention to the fact that models may have burners:

  • single-stage type;
  • two-stage type;
  • with power modulation.

If the regulation is done with a single stage burner, the power cannot be controlled. When choosing a model with a two-stage burner, you will receive equipment that has two levels of adjustment. With power modulation, control will occur based on a given temperature regime.

Classification by type of water heating

Liquid fuel boilers can also be classified according to the type of water heating. This equipment can be single-circuit, double-circuit or double-circuit with a built-in boiler. The first version of the devices is designed for space heating, the second, in addition to heating, will heat running water in the system, while the third will provide the house with hot and warm water.

Fuel consumption

If you are considering oil boilers as heating equipment for your home, thenestimated fuel consumption should be determined. The result of diesel fuel consumption can be calculated using the formula: RT (kg/hour)=0.1 × 10m2. Burner power is expressed in kW. If the boiler power is 15 kW, then 1.5 kg of fuel will be needed for one hour to operate the equipment. This volume will increase to 36 kg per day. For the heating season, the total data will be approximately 5 tons, this amount will be required for approximately 100 days. Ultimately, in monetary terms, the consumer will have to pay 150,000 rubles. This is true if oil-fired boilers for heating are installed in rooms with a total area of 200 m2.

When hot water is needed, you should also pay attention to high-quality models, in which the power is quite high, as well as the efficiency. This will eliminate additional service. The power of the boiler for efficient operation must be selected in such a way that this indicator is higher than the required rate. Condensing oil-fired boilers can save up to 15% on fuel. Over 20 years, insignificant savings will vary from 100,000 to 300,000 rubles. If the fuel consumption is one tenth of the power of the burner running, then the indicators will determine the selection criteria.

Additional types of liquid fuel equipment

The oil-fired heating boiler may differ in the type of burner used, which may be mounted or built-in. Last optiondesigned to burn one type of fuel, it can be, for example, diesel fuel. If you choose a model with a mounted burner, then it will be possible to change it, which will allow you to transfer equipment to fuel oil if necessary.

Liquid fuel burners of boilers, as you know, this is not the only parameter for classifying such devices. It is worth paying attention to another important indicator - the depth of fuel suction. Tanks with liquid fuels are stored in recessed containers or in the ground. In this case, the fuel suction depth must correspond to the depth of the tank location. If you need a liquid fuel boiler, the fuel consumption of which is not so high, then you should pay attention to the installation method, which was discussed above. Wall-mounted equipment has less power and is designed for hot water supply and space heating, the area of \u200b\u200bwhich does not exceed 300 m22.

Varieties of liquid fuel boilers according to the material of the furnace

If you are interested in the types of liquid fuel boiler, then you should additionally pay attention to the material in the base. The durability of the product will be affected by the quality of the material from which the firebox is made. In terms of economy, the steel boiler wins, but its service life is limited to only 15 years. Wear-resistant are premium models, the heat exchangers of which are made of high-alloy steel. As an example, consider the CTC Okotherm Unit, which has a cylindrical combustion chamber and a fairly high coefficientefficiency within 98%.

A diesel fuel oil boiler with a cast-iron chamber will be less economical in fuel consumption, but its productive work is designed for 50 years. The combustion of fuel will be accompanied by a large volume of sulfur, which will lead to the formation of condensate and the accumulation of liquid, which will cause corrosion processes that destroy the metal. The cast iron heat exchanger is not afraid of this, which ensures a long service life. The most suitable option is the choice of a boiler that can operate on all types of fuel, namely:

  • LPG;
  • fuel oil;
  • kerosene;
  • diesel fuel.

This approach will provide an alternative timely replacement.

Fuel consumption of GT 408-414 series boilers

Liquid fuel gas boilers are quite popular today, as an example of such equipment, we can consider the GT 408 and GT 414 K models, which will be discussed below. In total, the line includes 8 models, the first of which consumes liquid fuel in the amount of 650 kg per hour. The most powerful model will have this parameter within 1450 kg per hour. If we are talking about natural gas, then the first of the mentioned models will use 700 kg per hour, while the last one will use 1405 kg.

Conclusion

Before choosing liquid fuel boiler equipment, it is important to pay attention not to one, but to several parameters at once. For example, one of the important is the type of heat exchanger, which can be steel or cast iron. In the latter caseheat exchangers last longer, but will cost the consumer more. The equipment will have a more impressive weight, which can complicate not only delivery, but also installation work. And this will certainly entail additional costs for trucks and will make it necessary to resort to the services of professionals.
