Fabbri F 55 S.V. - Warm Air Wood Boiler (55 kW)

Natural draft, reliable power

The Fabbri F 55 S.V. offers 55 kW of heating power with a simplified, natural draft design. Unlike the C.V. version, it operates without a forced flue fan, making it quieter, easier to maintain and more energy-efficient. Ideal for workshops, warehouses and agricultural spaces requiring steady, low-maintenance heating.

The key difference: S.V. vs C.V.

The C.V. models feature a flue fan for forced exhaust, while the S.V. relies on natural chimney draft. Fewer moving parts mean lower energy consumption, less wear and easier servicing. For facilities with good natural flue draw, this model provides perfect efficiency with minimal complexity.

Built to last

The combustion chamber is made from chromed INOX steel with ribbed reinforcement and refractory lining. The galvanized outer shell and steel frame protect against corrosion and mechanical stress, ensuring long service life even under industrial conditions.

Quiet, clean and efficient

Without a flue fan, operation is whisper-quiet. Dual centrifugal fans at low RPM circulate warm air evenly, while elastic mounts reduce vibration. The heat exchanger transfers energy quickly and efficiently, achieving excellent combustion performance.

Ease of operation and maintenance

The intuitive control panel makes temperature adjustment simple. Cleaning and inspection are fast – removable fire grates and easy access to ducts reduce downtime. With no flue motor to service, the F 55 S.V. is as low-maintenance as it gets.

Applications

Perfect for small to mid-sized industrial or agricultural buildings. The natural draft system makes it ideal for sites where simplicity and reliability are key. Hewa provides setup support, documentation and accessories – see wood-boilers.
