Diesel heating of a country house - an alternative to gas

Heating

During the construction of the house, heating becomes a priority. Today, there are several options for its solution, each carries both advantages and disadvantages. For example, the main gas is convenient, but there is far from everywhere, firewood and coal are inexpensive, but they do not allow setting up an automatic heating system. If you have neither the one nor the other, and the electric line runs near the house, let's consider the option of heating the room with diesel fuel.

What to look for

Merits

installation of equipment does not require large funds when compared with other systems. You can install it with certain skills and your own hands;
before operating the diesel boiler, it is not necessary to obtain permits;
no need to install a complex chimney, just make a hole in the wall and bring it through it;
the equipment can be fully automated. The boiler will maintain the required coolant temperature in the system, and when it cools down, the burner will turn on independently and turn off when the set parameters are reached;
To get fuel today is not a problem.

disadvantages

the price of diesel fuel is constantly growing, besides only fuel of the highest quality and without impurities is required;
the need for electrical energy;
during operation, the equipment is noisy due to the operation of a liquid-fuel heating burner. The problem can be solved by additional sound insulation in the room with the boiler;
smell of diesel.

Getting started

Manufacturers of heating equipment offer household diesel boilers in a wide range, so there should not be any problems with the choice. The efficiency of such domestic heating boilers is within 75-85%.

It depends on the design features of the equipment and its type. For example, it is possible to purchase double-circuit boilers capable of heating rooms in a house and supplying it with hot water.

The first question in the fight against the heating system is its fuel consumption, in our case, diesel fuel. If the house is maximally insulated - 500-700 ml / h, usually 900 ml / h are taken into account with the constant functioning of the boiler.

Tip: before you go to the store for the equipment, select a place for it on the site.

For a landmark, you can take the standards of gas boilers:

area from 4 m2;
ceiling height from 2.2 m;
doorway width not less than 800 mm;
10 m3 for 0.3 m2 window opening;
supply ventilation 8 cm2 per 1 kW of rated power of the boiler or 30 cm2 / 1 kW if the air flow from the interior;
the flue pipe must have a cross section that is the same or larger than that at the outlet of the boiler;
ground loop;
natural ventilation in 300 mm from the ceiling;
electric power on a separate machine;
diesel fuel for heating, in the boiler room the stock is not more than 800 liters.

At arrangement of a diesel boiler room with a turbo burner, no special complex chimney is required. It is enough to get a coaxial and bring it through the wall.

Tip: modern equipment allows you to replace the diesel burner gas. Therefore, when the main gazovod comes to your house, you can save on the boiler.

Equipment power

The main source of thermal energy in diesel heating of a private house is the boiler. When calculating its power it is necessary to pay attention to:

building area;
ceiling height;
insulation layer;
number of window openings.

Consider also the following..

Boiler power (kW)	Maximum heating area (m2)
15	150
20	200
thirty	300
50	500
70	700

With a ceiling height of up to 3 m, the ratio is as follows: 1 kW per 10 m2. When installing a double-circuit boiler, add another 20% to the calculated value.
Another option when choosing - the material of the heat exchanger. Do not forget that in the composition of diesel fuel there is sulfur, therefore, when burning fuel, caustic condensate will form, which can cause corrosion, which will destroy the metal. We recommend to prefer heat exchangers made of cast iron or stainless steel.

Fuel storage tank

An important question, because without it you will have to constantly go after him to the gas station. It is necessary to choose a place where the tank will stand, and there must be a normal approach of the filling machine.

The instruction prescribes that the tank should not exceed 800 liters. However, this volume is definitely not enough to fully heat the building. Therefore, users often install containers for 2-4 cubes, in which case it should be outside the dwelling. This will increase the safety of operation and increase the area of the boiler house, removing large capacities from it.

For a country house usually use vertical tanks of 0.8-2 cubes. Based on them, you can create a fuel storage by combining the containers with fuel strapping. This will significantly increase the work of the boiler at one gas station.

Boiler room for individual heating of the house with diesel fuel

The material for tanks can be plastic, metal or fiberglass. There are also containers for underground storage. But, with volumes up to 2 cubes, this is not worth doing.

Tip: when storing containers in the open air, they should be carefully insulated against freezing.

Do not forget to provide a pump to supply fuel to the boiler room, if the tank is not located in it. The pipeline must be insulated and a fuel filter must be installed. In the room itself, we recommend installing a capacity of 200 liters for storing fuel for some time.

Conclusion

The use of diesel fuel for heating a cottage is an interesting autonomous solution that can be an alternative to other heating systems. When arranging it is necessary to take into account many factors that will help in solving the tasks. Installation of equipment is better to entrust experts.
