Liquid fuel boilers: types, consumption

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, servicing the second type of equipment involves a lot of trouble, whereas the electric model is too energy-intensive, so it is advisable to consider the alternative 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 a highway. But liquid fuel assemblies are structures that work on liquefied gas and other available types of resources. For example, diesel is the most popular type of fuel. For 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 solar oil is removed beyond its limits. The main advantage of such a system is the constant heat in the dwelling, as well as the autonomy of the devices.

Varieties by material and method of installation

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

Wall models differ categorically to the quality of diesel fuel, in addition, they are not the leaders of sales. And the external attractive steel case is made of hardened steel, has a heat-insulating layer that ensures heat retention and eliminates the heating of the walls. Maintenance will be reduced to monitoring the injectors and burners, the first of which spray the fuel. It will be necessary to clean the chimney, and if you resort to professional help, the cost of services will be very impressive. Liquid-fuel boilers can differ also by the method of heat generation. Diesel devices can be condensing or classic. The most technologically considered 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 ignition and heating of the heat exchanger. The heat is transferred to the heat carrier and is carried through the heating system. Through the chimney, vapors and combustion products are extracted, which pass through the heat exchanger and give it heat. If the boiler has an electronic control unit, it will automatically react to a malfunction by shutting down the system during operation.

When choosing such equipment, it is necessary to pay attention to the fact that models can have burners:

• Single-stage type;
• Two-stage type;
• With power modulation.

If the adjustment is carried out using a single-stage burner, then the power can not be controlled. When choosing a model with a two-stage burner, you will receive equipment that has two levels of adjustment. With the power modulation, the control will proceed based on the set 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, dual-circuit or dual-circuit with built-in boiler. The first version of the devices is designed for heating the premises, the second, in addition to heating, will heat the running water in the system, while the third one will provide the house with hot and warm water.

Fuel consumption

If you are considering liquid fuel boilers as heating equipment for your home, then you should determine the approximate fuel consumption. The result of the consumption of solar oil can be calculated using the formula: RT (kg / h) = 0.1 × 10m ² . The burner output is expressed in kW. If the boiler capacity is 15 kW, then 1.5 kg of fuel will be needed for one hour for the operation of the equipment. In a day this volume will increase up to 36 kg. For the heating season, the total data will be approximately 5 tons, this amount will take approximately 100 days. In the end, in monetary terms, the consumer will have to pay 150,000 rubles. This is true if the oil boilers for heating are installed in rooms with a total area of 200 m ² .

When hot water is needed, attention should be paid also to quality models where the power is high enough, as well as the efficiency. This will eliminate the additional maintenance. The boiler output for efficient operation must be chosen in such a way that this indicator is higher than the required rate. Condensing liquid fuel boilers allow you to save on fuel up to 15%. For 20 years, insignificant savings will vary from 100 000 to 300 000 rubles. If the fuel consumption is a tenth of the capacity of the operating burner, the indicators will determine the selection criteria.

Additional varieties of liquid fuel equipment

The fuel oil boiler can be different in type of burner used, which can be hinged or built-in. The latter option is designed to burn one type of fuel, it can be, for example, diesel fuel. If you choose a model with a hinged burner, it can be changed, which will allow the equipment to be converted to fuel oil if necessary.

Liquid fuel burners of boilers, as is known, is not the only parameter of the classification of such devices. It is worth paying attention to another important indicator - the depth of fuel suction. Tanks with liquid fuels are stored in deeper containers or ground. The depth of the fuel suction in this case must correspond to the depth of the reservoir. If you need a liquid fuel boiler, fuel consumption is not so great, then you should pay attention to the method of installation, which was discussed above. Wall-mounted equipment has a lower power and is designed for hot water supply and heating of premises, the area of which does not exceed 300 m ² .

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

If you are interested in the types of liquid fuel boiler, you should additionally pay attention to the material in the basis. The longevity of the product will be affected by the quality of the material from which the furnace is made. From the point of view of economy, a steel boiler wins, but its service life is limited to only 15 years. Wear-resistant are premium-class 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 rather high efficiency in the range of 98%.

A diesel fueled diesel boiler with a cast iron chamber will be less economical in fuel consumption, however its productive work is designed for 50 years. Combustion of fuel will be accompanied by a large volume of sulfur, which will lead to the formation of condensation and 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 to choose a boiler that can work on all types of fuel, namely:

• Liquefied gas;
• Fuel oil;
• Kerosene;
• Solar oil.

This approach will provide an alternative timely replacement.

Fuel consumption of GT 408-414 series boilers

Quite a big popularity today use a liquid fuel gas boiler, as an example of such equipment you can consider the models GT 408 and GT 414 K, the fuel consumption which will be discussed below. In total, the line represents 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 these models in an hour will spend 700 kg, while the latter - 1405 kg.

Conclusion

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