Pellet boiler Ferroli BioPellet Pro 24 kW, output range 7.5–24 kW, model LSBBP24T

The Ferroli BioPellet Pro 24 kW (model LSBBP24T) is a pellet-fired central heating boiler designed for residential and light-commercial applications. It operates across a modulating output range of 7.5–24 kW and is intended for integration with radiator or underfloor heating systems. The appliance uses wood pellets as fuel and features automated feeding and combustion control to maintain steady heat production and seasonal efficiency.

Advantages

The boiler provides modulated output to match building heat demand, improving fuel efficiency and reducing cycling. Automated pellet feed, ash removal features and combustion control simplify operation and lower maintenance frequency compared with manual solid-fuel systems. Compact design and standard hydraulic connections allow straightforward integration into existing heating circuits. The unit is engineered to operate with common heating distribution systems and supports stable temperature control for domestic hot water and space heating when paired with appropriate system components.

Suitable for

• Single-family homes requiring a pellet heating solution with output up to 24 kW
• Small multi-zone residential buildings or light-commercial premises with central heating
• Replacement of oil or gas boilers where pellet fuel storage and handling are available
• Hydronic radiator systems and underfloor heating installations

When it may not be suitable

This boiler may not be appropriate for very large buildings or industrial applications that demand continuous heat output well above 24 kW. It is also not suitable where pellet fuel supply, dry storage space, or ash disposal options are unavailable. Buildings that require zero on-site combustion (e.g., certain low-emission zones or properties with strict ventilation constraints) should consider alternative heat sources.

Key specifications

• Nominal output range: 7.5–24 kW
• Fuel type: wood pellets
• Application: central heating for radiators and underfloor systems
• Heat output modulation: automatic control to match demand
• Automation features: automated fuel feed and combustion management
• Installation: designed for integration with standard heating circuits

How to use

Install the boiler on a level, non-combustible base and connect it to the heating circuit according to the installation manual and local regulations. Provide a dedicated pellet storage area and a feed system or auger if required by the installation. Commission the unit with a qualified technician to set combustion parameters and hydraulic balancing. Normal operation involves monitoring the fuel level, periodic ash removal, and scheduled maintenance checks. Controls allow adjustment of target temperatures and operating schedules to match user requirements.

What to consider before purchase

• Ensure available dry storage space for wood pellets and access for deliveries
• Verify that building heat load falls within the boiler’s 7.5–24 kW output range
• Plan for flue/ventilation requirements and local installation permits
• Assess ash disposal arrangements and routine maintenance access

Usage recommendations

Use EN-standard wood pellets of recommended size and moisture content for consistent combustion. Schedule annual professional maintenance and clear ash and combustion residues at manufacturer-recommended intervals. Balance the heating circuit after installation and use appropriate controls to optimize efficiency across the 7.5–24 kW operating range.
