Pellet boiler Kiturami, advantages and disadvantages
Like any technical device, the Kiturami pellet boiler has both advantages and disadvantages. The first category includes:
- low cost. This unit has a cost two times lower than similar products from Europe;
- frugality. According to the average indicators for heating a room with an area of 100 square meters, for the heating period (6 months), the consumption for the operation of the boiler is 3-4 tons of pellet fuel. For the output power, this is a decently small indicator, especially when compared with analogues from other companies;
- significant efficiency. Due to the design functionality of the pellet boiler, the maximum heat removal is observed in the internal part of the unit, which is confirmed by a low smoke temperature, and the efficiency is 93%;
- hot water circuit. Pellet boiler Kiturami is a double-circuit device. The presence of this component of the boiler makes it possible to significantly save on electric boiler. The pellet boiler Kiturami KRP-20A produces water at a 60-degree temperature, nine liters every minute;
- fire protection system. At the end of the fuel supply conveyor at the burner intake, a temperature sensor is mounted, which is preventive measure the occurrence of ignition. If the temperature begins to exceed the permissible one, an electromagnetic damper is activated and the flame is extinguished with water located in a container specially designed for such cases;
- bulk coolant. The coolant located in the heat exchange compartment reaches a volume of 160 liters, which is twice as much as in similar models from other companies. Such an impressive volume eliminates the adverse effect of the cold outlet on the functioning of the boiler;
- pneumatic flushing of the heat exchanger. Given technical device serves to clean the heat exchanger, which is prone to contamination with tar, slag and fumes. Cleaning is carried out compressed air with a pressure of 9 atmospheres. The time interval for this procedure is regulated by the attached control unit. Based on the quality of the original fuel, cleaning is carried out weekly or once a month;
- thermostat with remote temperature sensor. This sensor allows you to control and regulate the modes of operation of the boiler and adjust the parameters while being at a distance from it.
disadvantages
The disadvantages that can be found when operating the Kiturami KRP-20A pellet boiler are expressed in the following factors:
- dependence on electricity. Along with the entire range of pellet boilers, KRP-20A is also energy dependent. Electricity is needed for the operation of fans, screw motor, cleaning compressor, heating element and control unit. It should be noted that electricity consumption is negligible. The most resource-intensive in this regard is a tubular electric heater, it needs about 400 watts to ignite, however, it takes 1 minute twelve times a day;
- slag formation. The use of a flare burner and low-quality fuel in the design of the Kiturami pellet boiler inevitably leads to the formation of slag deposits on the grates. Slag is fuel particles coking in high-temperature mode.
Slag formations prevent normal functioning boiler and cause the appearance of soot, pellet costs increase by 25%, respectively, the efficiency of the device decreases. To prevent such undesirable effects, KRP-20A is equipped with an automatic grate cleaning device from caked combustion products.
Also, in addition to the listed shortcomings, there are some minor imperfections in the assembly of the device itself, but its cost more than covers these small miscalculations.
Kiturami is constantly engaged in technical development and improvement of its products, and also strives to meet all the needs in the field of heating appliances of its potential and current customers.

More about boilers Kiturami KRP 20A
Kiturami KRP 20A - floor-standing pellet boilers for heating areas up to 192 m2 with built-in hot water function. The double-circuit heat exchanger works on special form fuel - pellets, which are pressed wood waste in the form of granules. All work processes of the unit are fully automated, and the control is performed by means of a remote control with an integrated room thermostat.
Kiturami KRP 20A" - main characteristics
The efficiency of the heating unit is directly determined by the quality of the pellets. Fuel pellets should be stored in a dry place - under the influence of moisture they are transformed into "harmful" wood flour. When such a formation is loaded into the fuel compartment, the heat exchanger power decreases (base value - 23.3 kW), efficiency drops (standard value 92%) and ash production increases.
The boiler has a built-in circulation pump, which increases the efficiency for the second circuit when generating hot water - 13.8 l / minute at temperatures up to 65 ° C. The maximum volume of the coolant provided by the design is 168 liters. The complete set of the heat exchanger includes the presence of a thermostat that performs a number of functions:
- selection of DHW heating temperature depending on the season;
- automatic "on / off" by time;
- autonomous operation without user intervention with support for the minimum set temperature;
- automatic protection against overloads and so on.
Kiturami KRP 20A consumes fuel efficiently - thanks to a special feed screw, pellets are automatically dosed based on the need for heat and the current stage of combustion. accelerating circulation pump together with expansion tank are pre-integrated into the structure of the thermal unit, which simplifies its installation.
The design of the boiler prevents backfire and allows you to quickly dispose of waste - the ash box is easily emptied, and periodic cleaning of the compartment does not cause even the slightest difficulty. For safe operation of the heat exchanger, double protection against overheating is provided, which is provided by a set of appropriate sensors. When operating at minimum temperatures during the cold season, the frost protection function will not allow the equipment to fail.
As a result, Kiturami KRP 20A is a reliable and extremely easy-to-maintain device that heats the working area specified by the manufacturer with high quality. The presence of a second circuit allows you to have regular volumes of hot water during all year round no extra charges for additional equipment.

Back to indexAdvantages and disadvantages of the KRP-20A boiler
Like any other device, the Kiturami KRP series boiler has its advantages and disadvantages. We will try to highlight the main pros and cons of this device. So, let's begin:
Advantages
The main advantages of this model are:
Low price
Low cost is perhaps the main argument in favor of this model. The boiler costs almost 2 times cheaper than European analogues.
Economy
On average, for a heating season lasting 7 months, for heating an area of 100 m2, the boiler consumes from 3.5 to 4 tons of pellets. This is a very good indicator among similar power models from other manufacturers.
High efficiency
Thanks to design features pellet boiler, the maximum heat removal occurs inside the boiler, as evidenced by low temperature flue gases. The efficiency in this case reaches 92-94%.
DHW circuit
The pellet boiler Kiturami KRP-20A is double-circuit. The presence of a hot water circuit allows you to save on a boiler indirect heating or electric boiler. The boiler is capable of producing sanitary hot water at a temperature of 60 °C at a rate of 9 liters per minute.
Fire extinguishing system
At the end of the pellet feed line, at the burner inlet, a temperature sensor is installed to prevent fire. When the temperature exceeds 95 C, the electromagnetic valve opens and the combustion is filled with water from a special reservoir.
Large volume of coolant
The volume of coolant in the heat exchanger of the Kiturami pellet boiler is 160 liters. This is about 2 times more than similar models from other manufacturers. Due to the large volume, it is excluded Negative influence cold return to boiler operation. It also allows you to significantly reduce the warm-up time of the entire heating system.
Pneumatic cleaning of the heat exchanger
To clean the surface of the heat exchanger from the ash, soot and resins deposited on it, the pellet boiler can be additionally equipped with a compressor. Cleaning is carried out with air under pressure of 8 atmospheres. The frequency of this process is controlled by the control unit. Depending on the ash content of the pellets, the boiler can be cleaned from once a week to once a month.
Remote thermostat
The presence of this device allows you to control and manage the operating modes and set the parameters of the pellet boiler while being at a distance from the boiler.

disadvantages
The disadvantages of Kiturami KRP-20A include:
electrical addiction
Like all types of pellet boilers Kiturami KRP-20A is volatile. Power supply is necessary for the operation of the burner fan, auger motor, cleaning compressor, control unit and electric heating element. However, the boiler consumes a small amount of electricity. The largest consumption is created by an electric heating element. In the pellet ignition mode, it consumes about 400 W, but this process takes 1-2 minutes 12 times a day.
Slag formation
The use of a flare-type burner and poor quality pellet fuel leads to the formation of so-called slag cakes on the burner grates. They are pellet particles sintered at high temperature. This process interferes with the normal operation of the pellet boiler and leads to soot, an increase in fuel consumption by 20-30%, and consequently to a decrease in efficiency. heater. To combat this phenomenon, the Kiturami KRP-20A model includes a block for mechanical cleaning of the grate from caked fuel pellets.
