Today, the task 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 these varieties can be found on the market at affordable prices. However, servicing the second type of equipment involves a lot of trouble, while the electric model is too energy-consuming, 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 main. But liquid fuel assemblies are structures that operate 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 removed outside. The main advantage of such a system is constant heat in the home, as well as the autonomy of the devices.
Varieties in material and installation method
If you are interested in liquid fuel boilers, then you should consider their main varieties. In the store, you should first of all pay attention to the material. Thus, the devices can be implemented 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 implies the need for installation on a plane, as well as their reliable position.
Wall-mounted models are categorical for the quality of diesel fuel, in addition, they are not leaders in sales. And the attractive external steel case is made of hardened steel, has a heat-insulating layer that provides heat retention and eliminates wall heating. Maintenance will be reduced to monitoring nozzles and burners, the first of which spray fuel. It will still be necessary to clean the chimney, and if you resort to professional help, the cost of services will be very impressive. Liquid fuel boilers may also differ in the method of heat generation. Diesel devices can be condensing or classic. The first are considered the most technologically advanced, which will ensure the efficient use of energy from the unit.
Classification of diesel equipment
The burner in the combustion chamber is responsible for igniting and heating the heat exchanger. The heat is transferred to the coolant and distributed throughout the heating system. Through the chimney, fumes and combustion products are removed that pass through the heat exchanger and give it heat. If the boiler has an electronic control unit, it will automatically respond to malfunctions by turning off 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 will not 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
Oil 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 intended for heating rooms, 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 consider liquid fuel boilers as heating equipment for your home, then you should determine the approximate fuel consumption. The result of the consumption of diesel fuel can be calculated using the formula: RT (kg / h) = 0.1 × 10m 2 . Burner power is expressed in kW. If the boiler power is 15 kW, then for one hour 1.5 kg of fuel will be needed for the equipment to work. This volume will increase to 36 kg per day. During the heating season, the total data will be approximately 5 tons, this amount will be required for about 100 days. In the end, in monetary terms, the consumer will have to pay 150,000 rubles. This is true if liquid fuel boilers for heating are installed in rooms with a total area of 200 m 2 .
When hot water is needed, you should also pay attention to high-quality models, in which the power is high enough, as well as the efficiency. This will eliminate the additional after-sales service. The boiler power for efficient operation must be selected so that this indicator is higher than the required norm. Condensing liquid fuel boilers can save up to 15% on fuel. Over 20 years, insignificant savings will vary from 100,000 to 300,000 rubles. If fuel consumption is a tenth of the power of a working burner, then the indicators will determine the selection criteria.
Additional varieties of liquid fuel equipment
A liquid fuel boiler may vary in the type of burner used, which may be mounted or mounted. The last 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 you to transfer equipment to fuel oil if necessary.
Oil burner boilers, as you know, is not the only parameter for the classification of such devices. It is worth paying attention to another important indicator - the depth of fuel intake. Liquid fuel tanks are stored in recessed containers or in the ground. The depth of the fuel intake should correspond to the depth of the tank. 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 and space heating, the area of which does not exceed 300 m 2 .
Varieties of liquid fuel boilers for furnace material
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 of which the furnace is made. In terms of efficiency, a steel boiler wins, but its life is limited to only 15 years. Premium models are wear-resistant, the heat exchangers of which are made of high alloy steel. As an example, we can consider the CTC Okotherm Unit, which has a cylindrical combustion chamber and a sufficiently high efficiency in the range of 98%.
A diesel fuel 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 is capable of working on all types of fuel, namely:
- liquefied gas;
- fuel oil;
- kerosene;
- diesel fuel.
This approach will provide an alternative timely replacement.
Fuel consumption of GT 408-414 series boilers
A liquid-fuel gas boiler is 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 for fuel consumption. In total, there are 8 models in the line, the first of which consumes 650 kg of liquid fuel 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 consume 700 kg in an hour, while the last - 1405 kg.
Conclusion
Before choosing a liquid fuel boiler equipment, it is important to pay attention not to one, but to several parameters at once. For example, one of the most important is the type of heat exchanger, which can be steel or cast iron. In the latter case, the heat 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 make it necessary to resort to the services of professionals.
