COMPACT PELLET CENTRAL HEATING BOILER
The ONYKS boiler, with an integrated hopper, is a newcomer to the Zębiec pellet-boilers portfolio. The equipment is distinguished by its compact, modern, and aesthetic design. Thanks to its compact size (height only 1.2 m), it takes up little space, and will fit into virtually any boiler room, even the smallest. The boiler is equipped with an integrated pellet hopper with a capacity of 60 l/43 kg, which can be extended with an additional hopper, increasing the storage capacity up to 140 l/98 kg. The opening side of the door cover can be changed to optimise space in the boiler room.
EASY CLEANING
A few simple movements with the handle under the hopper cover are enough to clean the heat exchanger mechanically. The burner, on the other hand, is cleaned automatically when the boiler is extinguished, or every 8 hours of continuous operation.
SIMPLE DESIGN
The modern three-draught boiler design is based on a vertical multi-tubular heat exchanger. The pellet combustion is carried out through a self-cleaning, automatic, inlet burner. The ONYKS pellet boiler has the Lider Kolor Pellets controller, which regulates the operation of 4 pumps and a mixing valve. Automation can be extended by connecting additional mixing-valve modules. The controller works with room and weather panels as well as an Internet module.
SUBSIDY FOR THE BOILER
The ONYKS pellet boiler meets the stringent requirements of Class 5 and Ecodesign for flue-gas purity. It is, therefore, an excellent choice when replacing a heat source with a new one using possible subsidies (e.g. The Clean Air Programme).

ONYKS BOILER ADVANTAGES
Compact design (only 1.2 m high).
Automatic burner firing-up, extinguishing, and cleaning ensure convenient use of the boiler.
