Sukom R40 - Wood boiler (40 kW)

Are you looking for a wood boiler that provides sufficient capacity for larger buildings or installations? The Sukom R40 wood boiler combines high power with flexibility in fuel choice. This makes it an excellent solution for installers and end users who need more power without compromising on efficiency and reliability.

Manual firing with wood and coal

The basis of the R40 is the manual firing of solid fuels such as logs and coal. The spacious centre door allows for easy refilling. This door also has an opening in which a pellet, oil or gas burner can be installed as an option. This allows you to easily convert the boiler to an automatic installation in the future.

High efficiency thanks to three-pass system

The Sukom R40 works according to a proven three-pass system:

• In the combustion chamber, heat is mainly released through radiation
• Along the water-cooled walls, heat transfer takes place through radiation and convection
• In the heat exchanger just before the flue gas outlet, transfer takes place through convection and conduction

This design guarantees maximum fuel utilisation. By optionally installing turbulators, the efficiency can be further increased to 92%.

Power for larger projects

With a capacity of 40 kW, this boiler is ideal for larger homes, commercial premises or agricultural buildings. The boiler supplies heating water at standard central heating temperatures of 90/70 °C and operates reliably at a maximum pressure of 2.5 bar. Would you like to optimise heat storage and distribution? Combine the Sukom R40 with a buffer tank for extra stability and efficiency in your system.

Robust construction and insulation

The boiler body is fitted with high-quality mineral wool to minimise heat loss. The exterior is finished with durable paint or powder coating, ensuring a long service life. With its sturdy construction, the R40 can withstand intensive use in both private and commercial applications.

Operation and air control

For wood and coal firing, the air supply is controlled by a mechanical draught regulator. This automatically controls the air damper on the lower door, ensuring stable combustion. If the boiler is equipped with an automatic burner, the air control is electronic for even greater ease of use.

Safety guaranteed

The Sukom R40 is equipped with all necessary safety features as standard. A safety valve protects against overpressure, while an integrated heat exchanger (safety cooling coil) can actively cool the boiler in case of overheating. This makes the boiler reliable in daily use and safe under all circumstances.

Certification and sustainability

The boiler fully complies with the European standard EN 303-5, is EcoDesign Ready and complies with the Serbian standard SRPS. This ensures you have a product that is efficient and environmentally friendly, even in the long term.
