Heating a country house with diesel fuel: advantages and

Heating on diesel is not the most common and popular solution to the problem of heating homes. However, in some cases, the use of diesel units is justified by the lack of alternatives or requirements for power and mode of operation. We want to talk about the features of diesel heating.

Diesel heating

Special features

Heating a house with diesel fuel is a relatively modern method of producing heat, based on the burning of liquid petroleum products in special installations (heating boilers on diesel) connected to the circuits of the coolant circulation water system.

Water circulates in the heating circuit, part of which is the boiler heat exchanger. In the burner unit is supplied diesel fuel, which is sucked by the fuel pump and sprayed, then mixed with air and fed into the combustion chamber.

The energy of combustion of the fuel is spent on heating the water to a predetermined temperature, then water flows through the wiring pipes to the radiators of the heating system, where it gives off its heat to the surrounding space. Then the cooled coolant returns through the return flow pipes to the heat exchanger, and the cycle repeats.

One of the problems of the early models of diesel boilers was low efficiency, as part of the heat energy went along with the exhaust gases into the chimney.

However, modern designs of heat exchangers and advanced fuel combustion systems have increased the efficiency of the plants up to 85% and more. This made it possible to somewhat reduce the cost of calories and without that expensive heat.

The main features of diesel heating are dictated by the properties of the fuel.

Liquid fuel determines the characteristics of the system:

• The energy supply is made automatically due to the operation of the fuel pump.. This saves you from having to throw in fuel every few hours;
• Due to the possibility of multi-stage or smooth adjustment, the operation of the unit is adjusted in accordance with the most optimal fuel consumption with maximum heat output, which also contributes to saving resources;
• Waste heat production is flue gases and condensate in the chimney.. No ash, ash or soot is observed. This greatly facilitates the care and maintenance of the system;
• Devices can have as small - a few kilowatts - and huge - a few megawatts - power;
• Delivery of fuel to the site and storage capacity is required. In winter, it is necessary to provide heating of the fuel, otherwise it will thicken and the pump will not cope with its transfer;
• The cost of one kilowatt-hour of thermal energy when using a diesel engine is one of the highest of all possible.

Note! If you want an economical heating system, or your budget is limited - you should not choose a diesel system, it is very expensive.

Benefits

For those who can not make a choice, we will list the main advantages of using liquid fuel installations. It is not always possible to connect the house to a powerful three-phase line or gas main, and firewood and coal are not available in all regions, so often diesel fuel remains the only alternative.

So, the main advantages:

• Automatic operation using a multi-level system of control and protection of equipment, control of operating modes and fuel economy. Properly organized and rebuilt system provides a level of comfort comparable to the urban;
• Low cost of heating equipment and connection. If we are talking exclusively about the purchase and installation of equipment, then this is the cheapest option of all the existing ones (only electricians are cheaper, but it requires a powerful line);
• Lack of chimney. Most modern devices are equipped with a turbine, which itself pushes the products of combustion, so instead of a chimney, it suffices to bring a coaxial pipe through the wall;
• For burning use bright furnace diesel. This diesel fuel with special additives, which is not used for refueling vehicles, and therefore is much cheaper, and the requirements for its composition is much softer;
• You can connect the equipment with your own hands without any approvals and permits.

Note! There is also the possibility of switching to the burning of used engine oil, but this requires a special burner, which costs about 60 - 70 thousand rubles. Savings with access to training will be huge.

disadvantages

Our story will be incomplete if we forget to mention the disadvantages of diesel heating.

Especially since there are plenty of them:

• High cost of heating. The price of furnace diesel fuel is 15 rubles per liter at the most modest rates, and if the consumption of diesel fuel for heating a house of 150 square meters. m. is about 5 tons of fuel per season in central Russia, then we get a figure of about 75,000 rubles. If there is no access to the bright diesel engine, you can multiply this figure by two, and this is without taking into account the cost of delivery;
• The need to install fuel storage. As a rule, for these purposes use special plastic or metal tanks with volumes from 800 to 4000 liters, which are installed in the boiler room or outside the house;
• High noise from oil burner. SNiP sets the maximum permissible noise level of 85 dB, which is very loud for residential premises;
• The presence of an unpleasant smell. Even systems equipped with a chimney emit some amount of combustion products into the boiler room. As a result, there may be a peculiar smell in the house;
• High requirements to the quality of the fuel make it necessary to install filters and find reliable suppliers, on the integrity of which you will depend.

Note! The main and main drawback, in front of which all the others are taken together, is the prohibitively high cost of thermal energy produced.

Equipment

When choosing a boiler, one should pay attention to its power, the number of heating circuits, the possibility of reconfiguration to other types of fuel, the level of automation and protection. The most qualitative and expensive are the models of such companies: Viessmann, DeLonghi, Ferroli, Bosch, Grundfos, Buderus.

Also cheaper models from Gorenje, Proterm, Vaillant, or Rifar have also performed well. These devices are practically not inferior in assembly quality and technology used, but at the expense of less popular brands cost less.

There are also a number of Korean manufacturers, whose products can be considered an excellent combination of affordable prices and European quality. This is Kiturami and Navien. Unfortunately, domestic products do not withstand competition and are ineffectively outdated developments of the USSR.

Note! More complete and detailed instructions for choosing a boiler are possible only if there is a wealth of data on the area and quality of the house insulation, system operation mode, radiator wiring configuration, etc.

Conclusion

Diesel heating is convenient, reliable and comfortable, but too expensive. Choose this type of heating is only in the absence of cheaper alternatives. Video in the article will help you see the features of the equipment.
