The Celsius Pellet 300 boilers can be integrated into any heating system, from radiator heating to underfloor heating.

Our boilers are designed exclusively for operation with wood pellets (DIN+ quality, 6-8 mm diameter). Their construction is similar to that of a traditional wood-fired boiler, but they are much more economical to operate. They operate at very high efficiency, are equipped with an air-cooled steel plate door, require minimal maintenance, and will serve you reliably for a long time.

CONTROL DOORS

The boiler body has three control doors for easy handling. The doors are made of three-layer (1.5, 3, 5 mm) steel plates in an air-cooled design. A heat-resistant cord ensures proper sealing between the boiler body and the door.

The upper door allows for cleaning the heat exchangers.

The middle door (fuel door) is used to connect the Oxi PRO 250C pellet burner head to the boiler.

The lower door serves to remove combustion residues accumulated in the ash chamber.

Above the combustion chamber, the heat exchanger system allows the exhaust gas temperature to remain low, ensuring the heat from the exhaust gas is utilized.

CASING

The boiler body is insulated with 30mm thick insulation. The outer casing is made of 0.8mm thick steel plate, attached to the boiler body with sheet metal screws. For an aesthetic appearance, the casing and doors are painted with electrostatic powder coating (RAL 9600 color). The doors close flush with the steel plate casing, and the door locking mechanism handle is equipped with a Bakelite knob to prevent overheating.
