It is worth preparing for cold days by choosing efficient and ecological solutions. The presented 8 kW SLIM pellet boiler will take care of every home interior not exceeding 100 m2. The device can also handle heating water according to the needs of users. The tank can burn biofuel - wood pellets from natural resources with a diameter of up to 8 mm. The efficiency of the 8 kW SLIM boiler reaches over 90%. This has been confirmed by tests, in which the pellet-fired device obtained the 5th class in accordance with the EN 303-5 standard.

In addition, the heating boiler meets the strict ecodesign standards of EcoDesign - its energy class is A+, so energy efficiency with low energy consumption is at a very high level. It is necessary to mention not only the power offered, but also the low emission of PM below 20 mg/m3, which can be significant when applying for subsidies for the replacement of an old heating device.

The 8 kW SLIM boiler owes its efficiency in biofuel combustion to modernly designed QPELL burners, a blower fan and a microprocessor boiler controller. It is the PellPal PID controller that is responsible for the operation of the blower, the combustion process, and thus for supplying the required dose of fuel to the burner. If standard heating models are not enough, for householders who value appearance and readability, there are controllers equipped with color and touch LCD displays that will facilitate the use of the device.

The 8 kW SLIM boiler for pellets can operate in an open and closed system. For this purpose, the system should be equipped with the necessary accessories by assembling an external coil, an expansion vessel and a SYR 5067 and DBV2 thermal protection valve. The selection of elements for the SLIM boiler will depend on the selected security technique. Therefore, if household owners care about ecology, high thermal efficiency and lower power consumption, the PELLPAL 8 kW SLIM boiler will be perfect.

Construction of the PELLPAL SLIM boiler for pellets with a power of 8 kW

The boiler body and outer jackets are made of certified boiler sheet P265GH with a thickness of 5 mm. Individual elements of the boiler are laser cut, which ensures maximum accuracy and 100% repeatability of individual elements that make up a given heating device.

The structure is based on an exchanger with horizontal convection channels located in the upper part of the furnace chamber. The fuel tank is located above the boiler body. Placing the fuel tank above the boiler body also allowed to obtain a small width of the heating set, which can be used in small rooms. The capacity of the pellet tank in the 8 kW PellPal SLIM boiler is 45 kg, the volume of the tank is 61 liters.

The boiler is equipped with tightly closed doors that enable boiler maintenance, cleaning of convection channels and combustion chamber. In the lower door of the body there is a modern QPELL pellet burner. The fuel is supplied to the burner by a screw conveyor and poured down through a spiro pipe. The use of a spiro pipe protects the fuel tank against fire entering it. The chimney outlet (flue) is located at the back of the boiler, at the top at an angle of 45 degrees and directed upwards.

Connection pipes for connecting the boiler to the heating system are located on the top of the boiler and in its rear part. Before connecting the boiler to the system, place it on a stable surface and level it using the feet provided with the heating device.

The boiler operation is controlled by the PELLPAL PID microprocessor boiler controller. It has initial settings of the device adapted to the given heating power of a specific boiler, selected in such a way that the process of firing up and then burning and heating water in the central heating system runs efficiently and economically. The controller has the function of automatic ignition of pellets in the burner using the igniter located in the combustion chamber.
