Review of Kiturami diesel boiler models: how to make the right choice

Even at the stage of designing heating in a house, you have to operate with the general technical characteristics of the boiler, but in the end you still need to go to the store and choose a very specific model from the huge assortment on the market.

It will be useful to find out in more detail what a Kiturami diesel boiler is, what models are in the line, and how they can be better than other offers on the market.

Features of Kiturami boilers

Kiturami is a South Korean company with more than half a century of experience in the development and production of heating boilers and related equipment.

During this time, the company became one of the leaders in the domestic Korean market, and also found a large sales market in North America and nearby Asian countries. In our country, Kiturami boilers have been officially distributed for at least ten years and have already managed to show their good side.

The main emphasis in promoting boilers is on the introduction of innovative technologies and, in particular, our own developments, which have no analogues from other manufacturers or determine the narrow specificity of the equipment’s operation.

Diesel boilers, by definition, are not considered as the main model range for a wide range of applications. In terms of economic feasibility, they are inferior to gas, electric and even solid-state boilers. However, they are still in demand among consumers due to a number of reasons why liquid fuel is becoming preferable.

In remote areas of residence, where there is no stable connection to power grids and no gas supply, the issue of fuel availability becomes acute. At the same time, the heating of the house must, by definition, work uninterruptedly throughout the entire season. If for many countries such situations are rather the exception to the rule, then for us, on the contrary, they are commonplace, the reason for which is the vast expanses that separate populated areas.

Diesel fuel, unlike gas, is easier to transport and easier to store with minimal risks to life and the environment. Unlike solid fuel boilers, diesel fuel, when burned, provides uniform heating and a greater degree of control over resource consumption. And finally, the design of a diesel boiler and, in particular, the burner does not limit the use of other heat sources.

With minimal changes, a diesel burner can be replaced to use blue fuel, and boilers equipped with an extensive combustion chamber and grate can quickly switch to using coal, wood or pellets.

Kiturami diesel boilers are highly technologically advanced and are ideally balanced equipment for using diesel fuel as a heat source, and at the same time they are excellent for the listed types of conversion to operate on gas or solid fuel. So constructive and functional flexibility is the first significant advantage.

Kiturami boilers often use their own developments and a unique layout. On the one hand, this reduces the maintainability of heating equipment, but on the other hand, it ensures the highest boiler efficiency and balanced operation while observing simple and transparent operating rules. This is the second good reason to turn our attention to diesel boilers from South Korea.

The last advantage is the cost of boiler equipment. Even taking into account the high performance and proven quality of the boilers, their cost does not exceed the market average among similar offers.

So it turns out that Kiturami boilers have three features: a balanced design, high efficiency and an affordable price.

Blitz tips

• Diesel single-circuit and double-circuit models have been developed, the latter are more convenient, but more expensive. If you choose the first option, you will need to purchase a boiler and other appliances and accessories, but its cost will still be lower.
• It is worth paying attention to the depth of the fuel intake according to the criterion for determining the deep location of the fuel and fuel tank. According to fire safety, fuel tanks must be buried in the ground to an appropriate depth. At low power, the intake depth is higher.
• The cost of installing the equipment will include the price of the heater , its installation, startup and commissioning work, maintenance and spare parts for its repair.

Specifications

The operational characteristics, dimensions and parameters of Turbo series boilers are presented in the table below. It is clearly seen that the series of floor-standing diesel boilers covers a power range from 10 to 35 kW, which is quite enough to heat houses up to 250-275 square meters. Part of the heat will be used to prepare hot water, which must be taken into account in the calculations.

All Kuturami double-circuit boilers and heat exchangers, by the way, are ideally designed specifically for these tasks.

Fuel consumption

Fuel consumption is indicated in the table with technical requirements. However, please remember that actual consumption depends on individual settings. Based on the actual power required to heat the house, an appropriate nozzle is selected from the set offered by the manufacturer.

Thermal power, fuel consumption and fuel combustion mode are set. The parameter indicated in the table displays factory presets sufficient to ensure proper performance provided that only high-quality fuel is used, more often this means diesel fuel with winter additives that do not allow it to thicken or separate paraffin in excess of the norm.

In a real situation, for a boiler model with a power of up to 15 kW, you can expect fuel consumption at the level of 8 liters per day , taking into account the frequency of burner operation and the optimal temperature regime in the house. However, this is not the limit.

The right approach to choosing a heating mode, as well as installing a controller with variable temperature conditions, for example, depending on the time of day and day of the week, can reduce consumption even more.

Chimney

Cuturami boilers, gas, diesel, floor-mounted or wall-mounted, are mostly equipped with a closed combustion chamber and, accordingly, a forced exhaust gas removal system. The Turbo series we are currently reviewing is no exception.

Chimney installation diagram

The chimney for boilers is coaxial to simultaneously supply fresh air from the street and remove exhaust gases. Since the exhaust temperature after passing through the heat exchangers is no longer high, the requirements for the heat resistance of the chimney are reduced, and the list of acceptable materials is expanded.

In the best case, a steel coaxial chimney is still used, but a ceramic vertical chimney with a group of internal separate channels for supplying air, removing gases from the combustion chamber and ventilating the boiler room can be effectively used in the same capacity.

The size of the chimney is strictly indicated in the boiler specification and operating instructions. For the entire Turbo series it is 80 mm.

If desired, you can make a chimney with a slightly larger diameter, but no more than 50% above the specified value, that is, up to 120 mm.

Under no circumstances should the size and cross-section be reduced. Even though the removal of combustion products is forced, the resistance of the chimney will greatly affect the combustion mode and the quality of fuel combustion.

turbo 13r

The boiler model number corresponds to the amount of heat generated per hour - 13,000 kcal/hour. Converted to conventional kilowatts, the resulting value is 15.1 kW.

The declared power is enough to heat a house with an area of ​​up to 150 m2. Naturally, one should take into account the heat costs for preparing hot water. If a significant consumption of hot water is predicted, and regularly, then the thermal power for the heating circuit will naturally be lower.

Reliability and balanced operation, combined with the affordable cost of the boiler, gives a clear advantage in the case of using several boilers simultaneously in one building, for example, when dividing the heating circuit for each floor separately or when covering a large area in two more directions.

Owner reviews

“In 2012, a Kiturami 17R boiler was purchased. Great purchase. He was supposed to work as a backup for the Evan Epo-18 electric boiler, which acts as the main one in the heating system. Since an area of ​​150 square meters was heated. m, then the choice specifically fell on equipment with increased power. In severe frosts, the main boiler cannot cope with maintaining the required temperature conditions and stops working due to a drop in voltage in the network. Kiturami acts as a lifeguard, heating and providing water.” Tambov, Arkady

“The Kiturami Turbo boiler is of interest for hot water due to the presence of the SHOWER function, which is capable of producing a small volume of hot water in a short period of time.” Sochi, Marina

“Wonderful equipment. No matter how many such systems have been installed, practically no one has any complaints. All of Siberia is heated by them.” Ekaterinburg, Sergey

“The cost of this equipment alone can attract interest. Spare parts are always available, the remote controls are unified.” Moscow, Konstantin

“We have our own complaints about the boilers of this company. In my opinion they are not entirely reliable. So we had to resort to repairs twice. Automation can’t handle it.” St. Petersburg, Alexander

turbo 17

Kiturami turbo boiler
Thermal power already reaches 19.8 kW, which is enough to cover the heating of a house with an area of ​​up to 180 m2. It is possible to reasonably increase the upper performance threshold by selecting the appropriate nozzle on the burner, however, this will affect fuel consumption.

This approach allows you to solve the problem of increased hot water consumption so that you don’t have to worry about using hot water even in the most severe frosts without extra costs.

turbo 30 r

The most powerful model in the Kiturami line of liquid fuel boilers. A productivity of 34.9 kW makes it possible to heat a room of up to 350 m2, but at the same time the cost of the boiler at retail is approximately 45-46 thousand rubles , which is undoubtedly an attractive option.

As in the entire line of boilers, burners with a unique torch shape and optimal fuel combustion mode are used.

A minimum amount of nitrogen oxides is recorded in the exhaust, which indicates the high environmental friendliness of the equipment.

Settings

It is better to entrust the initial startup and setup of Kiturami boilers to a specialist who can correctly determine the optimal operating mode, select the desired type of nozzle and check the fuel consumption depending on its characteristics and even the method of connection and location of the fuel tank.

Nozzle for diesel boiler

For self-installation, detailed instructions are included with the boiler, according to which you can determine the operating mode closest to the design value.

The main thing is to adhere to the sequence of actions defined in the technical documentation and visual aids for putting the equipment into operation.

Setting up and adjusting the boiler settings should be carried out not only at the first start-up, but also during maintenance before each new season and to switch to summer mode, in which only the DHW circuit will be used.

Operating rules

The user controls the Kiturami boiler via a thermostat. Settings are made using knobs and buttons. Information about the current state of the unit is displayed by indicators on the display and lights.

Main functions:

1. Room. The main mode that is used when people are in the house. To activate, press the “Presence” button and set the desired temperature using the regulator.
2. Dream. Helps save fuel while on vacation. To switch, press the “Sleep” button and set the required temperature. The settings will remain in effect for five and a half hours. Then the “Indoor” mode will be restored.
3. Bath. Allows you to use a large amount of hot water for two and a half hours. After the expiration date, the device switches to the previous activated mode.
4. Absence from the premises. Used to prevent the heating system from freezing when the user is away. It assumes fuel savings by reducing the temperature to the minimum permissible.
5. Timer. Allows you to program the boiler operating time and shutdown.

For long and uninterrupted operation of the equipment, you must strictly follow the rules of its use.

Operating rules:

• Do not store combustible or flammable objects and substances near the device;
• have a fire extinguisher in the boiler room;
• Do not repair or disassemble the unit yourself;
• prevent freezing of water in the heating system;
• carry out maintenance 1–2 times a year;
• clean the chimney and chimney of soot several times a year;
• When dirty, drain the sediment from the fuel tank and change the filter.

Malfunctions

Kuturami boiler equipment is equipped with a full-fledged self-diagnosis system based on the operation of a number of sensors. The controller is able to assess the condition of the equipment, as well as the current operating mode, and respond to any deviations or problems that arise during operation.

In any emergency situation, the main action assigned to the boiler controller is to stop the burner to prevent significant consequences.

A well-developed self-diagnosis algorithm allows you to identify the problem and indicate the error code on the display so that the user can quickly take all necessary actions to repair and restore functionality.

Frequent breakdowns of Kiturami diesel boilers include:

• No ignition (error code 01);
• Does not start, there are no messages on the display.;
• Coolant leakage (depressurization of the heat exchanger or one of the pipeline connections);
• The flame periodically goes out with an emergency stop of the boiler;
• There is no draft, the operation of the boiler is accompanied by the flow of smoke and exhaust into the room.

Error 01 and solution

If error code 01 appears on the boiler display screen, it means that for some reason the fuel did not ignite, there is no torch, the controller forcibly stops the fuel supply, displays an error message, and signals the problem to the user.

Solving the problem requires precise execution of a procedure that can identify the source of the problem and eliminate the obstacle in the operation of the boiler as effectively as possible.

Briefly, the procedure looks like this:

1. Check the supply voltage;
2. Check the fuel line for integrity or capacity;
3. Check the condition of the fuel filter; if the scheduled replacement is close, it is better to change the consumable immediately;

4. Especially for 21R and 30R boilers, check that the fuel does not flow by gravity;
5. Change the fuel for testing to another one, if possible of a higher quality. Alternatively, it is possible, by acting on the air damper, to promote the supply of a rich fuel mixture into the combustion chamber;
6. Check or replace the fire control photosensor;
7. Check and clean the injector and ignition electrode;
8. Check the transformer that supplies the spark to the electrodes.

Quite often, the fuel-air mixture is supplied under too much pressure into the chamber and therefore does not have time to ignite from the electrode. The problem is solved at the 5th step of the algorithm by adjusting the air damper, which causes a mixture with a changed concentration to enter the chamber.

Doesn't start

The most unpleasant situation is when the boiler simply does not turn on. There are no signals on the display, and accordingly there is no error code by which the malfunction can be determined.

In such a situation, it would be appropriate to call a service center specialist who can understand the situation and give the correct verdict, as well as determine the repair procedure. You can independently only check the presence of voltage in the network, as well as the fuses in the boiler.

Leak

Most often, a leak means that the seal has been damaged in some connection of the pipeline inside the boiler. It is enough to inspect the equipment and determine the location of the leak and replace the gasket.

The heat exchanger in Kiturami boilers is made of alloy steel and copper, so it does not leak without obvious errors in the selection of coolant or mechanical damage.

Burner goes out periodically

The most common cause is a malfunction in the burner settings. It is important to adjust its power and, using a gas analyzer, determine the optimal air/fuel ratio for complete combustion. You can’t do such work yourself, so it’s better to contact a service center ="495″[/img]

Installation nuances and requirements

The installation of a Kiturami diesel appliance must be carried out by qualified specialists with special permission. The equipment is located in a separate non-residential premises. The boiler room must be well ventilated.

Burner settings and efficiency

The Kiturami diesel burner is adjusted before putting the device into operation or when performing maintenance. The adjustment is made by moving the air damper screw until the flame reaches the desired shade.

The efficiency of the burner is determined by the color of the flame:

• black and red - it is necessary to increase the air supply;
• bright white - signals the need to close the damper;
• yellow-red - is optimal, in this case the burner operation is considered effective.

The flame should be even. If the torch deviates to the side, it indicates the need to replace the nozzle.

Boiler piping

Connecting the Kiturami boiler to utility networks must be carried out in accordance with the instructions.

The harness includes connection to:

• heating system;
• DHW circuit;
• chimney and pipe;
• electrical networks;
• fuel line.

When connecting to heating and water supply pipes, shut-off valves and filters are installed. To compensate for the expansion of the coolant, special tanks are used. In systems with forced circulation, pumps are installed.

For the operation of Kiturami diesel heat generators, it is necessary to connect to a 220 V network. The device is provided with a separate socket located at a distance of at least 30 cm. If there are voltage drops, it is recommended to install a network stabilizer. Grounding is carried out to a depth of at least 30 cm.

To remove flue gases, a special set of forced exhaust pipes is used. The horizontal section of the chimney is placed at an angle of 5 degrees to prevent precipitation and condensation from getting inside.

The device is connected via a fuel line to a container with diesel fuel. Using a pump, fuel is pumped into the system, passing through the fuel filter, and supplied to the burner.
