Review of the best according to the editorial board. On the selection criteria. This material is subjective and does not constitute advertising and does not serve as a purchase guide. Before buying, you need to consult with a specialist.

Pellets are a type of solid fuel obtained from the processing of sawdust, agricultural waste and peat. This is a relatively cheap raw material that allows you to get enough heat for heating in places where there is no gas pipeline. For fuel combustion, pellet boilers are used, which have a special burner inside, on which the pellets are located. The fuel supply is supplied manually or from the bunker. There are models with automatic operation and mechanical adjustment. The rating of the best pellet boilers, based on the reviews of the owners and the characteristics of the equipment, will help you understand the advantages and disadvantages of the most popular models and choose the right one.

Heiztechnik Q BIO DUO 35

Rating: 4.9

The first place in the rating among pellet boilers is occupied by an apparatus from Italy. The model is proudly called DUO, since it has a double firebox in its design. This increases the amount of warm air acting on the heat exchanger, so the efficiency from the burned pellets is 88%. In addition to the pellet burner, the model has a steel grate that allows you to lay firewood on it. This is very practical in the event of a power outage, when the automatic pellet feeding stops working – it will be possible to maintain heat in the house manually. The owners in the reviews like that thanks to the HT-tronic 500B module, you can set up automatic operation and not interfere with the process for 3-12 days. This is facilitated by a spacious 300 liter hopper.

Our experts have awarded the pellet boiler the first place in the rating for several indicators at once. The model is distinguished by increased safety, since it has a fire extinguishing system in the bunker if the flame accidentally gets there. The boiler is also in the lead in power of 35 kW, which is enough to heat a house with an area of ​​120 to 350 m². Water-filled grates are easier to clean because they are profiled rather than tubular.

Advantages

• microprocessor control;
• you can set up automatic operation without human intervention for up to 12 days;
• Efficiency 88%;
• capacious bunker for 300 liters;
• convenient display for entering settings and rubberized touch buttons.

• difficult to transport due to the weight of 556 kg.

Kiturami KRP 20A

Rating: 4.8

The second place in the ranking is occupied by the South Korean brand. The pellet boiler has a power of 30 kW and is suitable for heating a large house with an area of ​​up to 300 m². The model heats water in a heat exchanger from 50 to 85 degrees. In case of overheating, a thermal safety valve is triggered and cold water is supplied to the boiler system from the water supply system, which immediately eliminates the threat of equipment failure. The hopper holds up to 250 liters of pellets and features a convenient loading funnel (located on the side of the burner, so maintenance is convenient). For an hour of operation, a pellet boiler is capable of burning up to 5 kg of fuel. Users in the reviews note the convenience of auto-ignition and quick heating, thanks to the blower fan. To keep the heat exchanger clean, there is a vibration cleaning function.

We have included the product in the rating due to its quiet operation. The boiler is insulated with a special material that absorbs the sounds of fuel combustion and the work of the mechanics. Two circuits in the system allow it to be used for heating the house and heating the bathing water.

Advantages

• Efficiency 92%;
• bunker for 250 l;
• automatic diagnostics;
• room thermostat;
• overheat protection.

disadvantages

ACV ECO Comfort 25

Rating: 4.7

The third place in the rating is occupied by a pellet boiler from a Belgian manufacturer. This is a 25 kW unit, which is enough to heat a house of up to 200 m². Inside there is a small copper heat exchanger of 97 liters. This allows the water to heat up faster and transfer heat through the pipes. More expensive competitors in the rating have heat exchangers of 120 liters or more. The pellet boiler is ignited automatically by pressing the button. Power is smoothly regulated, which is convenient depending on the season. The walls of the firebox are made of steel, 5 mm thick, which will not allow them to burn out in the next 10-20 years. The owners in the reviews share that the bunker is universal in terms of fastening and can be fixed both on the right and on the left side of the boiler, and this makes installation easier.

In our opinion, the product has earned a place in the ranking of the best, as the most not picky about the quality of pellets. Although there is a restriction on the size of the pellets, even industrial pellets can be burned in it, since the burner is made of thick cast iron and does not burn out from the sticking of fuel particles.

Advantages

• bunker for 240 liters;
• simple connection to the heating system through a 1-inch pipe;
• a small volume of coolant 97 l warms up rather;
• the thermal insulation of the casing reaches a thickness of 3 cm;
• forced air supply to a closed combustion chamber.

disadvantages

• large dimensions 1542x980x1217 mm;
• empty boiler weight 430 kg;
• a closed combustion chamber will not allow heating with wood;
• only suitable for pellets with a diameter of 8 mm and a length of 30 mm.

ZOTA Pellet 15S

Rating: 4.7

The fourth place in the rating of the best pellet boilers belongs to the Russian model with a capacity of 15 kW. The equipment has a control panel with a display and touch buttons. In addition to setting the amount of fuel and air supplied to the furnace, the automation can control 5 pumps that pump the coolant. It is convenient for a large house of 150 m². Users in the reviews share that the boiler calculates and stores in memory the volume of the passed fuel, and this allows you to calculate how many pellets will be needed for the next year for heating. You can heat both hardwood and coniferous pellets. The boiler also has an open combustion chamber, so if the light is turned off and the automation stops, it will be possible to open the firebox and maintain the coolant temperature with ordinary firewood.

Our experts have rated the boiler due to the special shape of the burner. Due to the specific design, combustion takes place mainly in the upper part, which protects the screw from burning out. Optionally, a GSM module can be connected to the boiler, which allows you to control the switching on and settings remotely, for example, from work or from a vacation location.

Advantages

• air supply adjustment;
• display with touch buttons;
• the height of the hopper is adjustable with a screw-in foot;
• smooth power change;
• connection to the control panel of circulation pumps up to 5 units.

disadvantages

• weight 333 kg;
• inconvenient size of a branch pipe for connecting heating – 2 inches;
• only 1 year warranty;
• not designed for pipe pressure over 3 atm.

Teplodar Kupper OK 20 with pellet burner

Rating: 4.6

The fifth place in the rating is occupied by a pellet boiler from the Russian manufacturer 'Teplodar'. The power of the device is 20 kW and it is suitable for a house with an area of ​​200 m². A design feature is the installation of the burner in place of the ash door. In the event of a short-term power outage, firewood can be thrown into the firebox through the open hatch of the combustion chamber. If the light went out for a week or more (a serious breakdown on the line), then the burner is dismantled and the boiler is fully used as a solid fuel. The efficiency of the model is 88%. The owners in the reviews like the vertical shape of the boiler (the bunker is not mounted on the side, but on top), which saves space in the boiler room.

We marked the pellet model in the rating due to the presence of an electric heating element of 6 kW. It promotes accelerated heating of the coolant during cold start times (when the entire system has not been heated). The heating element can also be used to maintain the temperature of the water in order to save pellets (heat the coolant with pellets and switch to electricity). This is practical for regions where fuel delivery is difficult.

Advantages

• saving space in the boiler room;
• powerful internal fan;
• easy to convert to solid fuel;
• the outside remains almost cold thanks to the basalt insulation.

disadvantages

• inconvenient hatch for loading pellets;
• only one circuit for heating;
• thermostat is not included in the package;
• the boiler legs are not height-adjustable – if the floor is uneven, you need to put something underneath.

Pelletron 40 CT

Rating: 4.5

This place in the rating is occupied by another model from a domestic manufacturer. The pellet boiler is endowed with a capacity of 40 kW, which surpasses the performance of even the TOP leader, but the unit loses due to the lack of automation. It is necessary to operate the boiler manually – mechanically set the opening angle of the airlock to the combustion chamber and the volume of supplied air. But users like economical consumption – for 1 hour of operation, the boiler burns up to 230 g of pellets. The capacity of the hopper for 320 liters is enough for several days. Fuel pellets fall into the furnace due to their own weight, without the participation of pushers and other elements, which increases the reliability of the process. The efficiency of the pellet plant is 92.5%. For fire protection, the model has a fire extinguishing valve.

The pellet boiler was included in the rating due to the presence of a smoke exhauster. This allows it to be used without an expensive high chimney, but only with a short pipe for removing combustion products outside the room. Such a design is practical in houses surrounded by tall buildings, which would reduce natural draft.

Advantages

• affordable cost;
• easily removable torch for easy cleaning;
• suitable for premises with an area of ​​400 m²;
• a convenient bunker for filling pellets.

disadvantages

• mechanical regulators of fuel and air supply;
• no display;
• only one circuit.

Ferroli SFL 3

Rating: 4.4

On the seventh place in the TOP is the Italian pellet boiler. It is assembled from cast iron plates tightened with metal studs. The body is decorated with sheet metal. The fuel is supplied manually through an open combustion chamber. Pellets are poured into the firebox on a grid with grates. To prevent them from spilling out, a protective fence is provided. Optionally, the boiler can be converted for automatic feeding of pellets, but this requires additional investments. The pellet unit is suitable for heating areas up to 190 m². The small heat exchanger with a volume of 26 liters heats up even faster due to the U-shape that surrounds the combustion chamber on three sides. The Italian manufacturer provides a 3-year warranty for the boiler.

According to our experts, the product should be in the rating due to the cast iron heat exchanger. Unlike other models with a copper or steel circuit, the element here will withstand elevated temperatures and is not susceptible to fouling of a film that impairs heat transfer. Another model with dimensions of 940x510x520 mm is more compact than its competitors.

Advantages

• 3 year warranty;
• the heat exchanger holds 26 liters;
• loading chamber with a capacity of 48 liters allows you to fill it and not look in for several hours;
• affordable price.

disadvantages

• no hopper and no automatic feeding system (purchased separately);
• Efficiency 79%;
• weighs 193 kg.

Stropuva S20P

Rating: 4.3

The eighth place in the ranking is occupied by a product from the Lithuanian brand Stropuva. The model has a power of 20 kW and is suitable for heating a house area up to 200 m². The unit operates according to a single-circuit scheme, but, as an option, an indirect heating boiler can be connected to the chimney. The pellet boiler operates with a programmer located on the left side of the body. To increase the draft, the outlet fan operates. Both pellets and firewood are allowed to burn in the firebox, and the length of the latter is allowed up to 45 cm, which the owners like in the reviews. To prevent accidental loss of heat from the firebox, the model is equipped with powerful lock handles.

We have added the pellet boiler to the rating as the most compact one. Although the unit is not small, due to its cylindrical shape, it takes up little space on the floor, therefore it is suitable for a boiler room with an area of ​​1.5 m². The manufacturer also offers seven color options for the body, from olive to red, which is convenient for choosing an interior in case the boiler is installed in a kitchen or bathroom.

Advantages

• automatic release of excess pressure;
• simple connection to the heating circuit through a branch pipe with a diameter of 32 mm;
• autonomous combustion up to 31 hours;
• pressure gauge on the body.

disadvantages

• designed for a system pressure of no more than 1.5 bar;
• there is no automatic feeding of pellets and a hopper;
• weight 235 kg;
• heat exchanger made of steel.

Bourgeois-K MODERN-12

Rating: 4.2

The ninth place in the rating was awarded to the Russian pellet boiler with an open combustion chamber. Fuel is supplied through a hole with dimensions 190×190 mm. The thermal power of the unit is 12 kW, which is enough to heat a standard private house with an area of ​​120 m². Pellets are loaded into the furnace in a large batch to the top and burn autonomously for up to 8 hours. The power is regulated in a primitive way, by opening the lower hatch for air passage and reducing the throughput of the water circuit. The efficiency of the model is 82%. The heat exchanger will withstand pressure up to 4 atm. Heating of the coolant is possible up to 95 degrees, and the temperature of the gases in the chimney reaches 190 degrees, so the installation of an indirect heating boiler is beneficial.

The main advantage of the boiler is its affordable price. In addition to pellets, you can heat the room with firewood, 55 cm long, which users like in the reviews. Safety is thought out in the unit: the firebox door is equipped with a pusher that moves the heat deeper, and the ash drawer hatch is trimmed with a seal that prevents gases from flowing back.

Advantages

• there is a stop on the door that pushes the heat deeper;
• ash box with a pull-out pencil case;
• attractive price;
• pressure gauge and automatic release of excess pressure;
• the ash compartment door is finished with a non-combustible seal.

disadvantages

• primitive construction;
• manual adjustment of the air flow (opening the hatch at the bottom);
• no fan;
• there is no pellet feed hopper.
