Prema B50 Heating Oil: Renewable Blend
Prema B50 Heating Oil is a commercial fuel formulated by blending 50% premium conventional heating oil with 50% HVO meeting the EN15940 specification. This heating oil provides industrial facilities with an initial, practical mechanism to transition toward net-zero targets.
It operates as a direct drop-in replacement for standard heating fuels, delivering a verified reduction in greenhouse gas emissions without necessitating capital expenditure on renewable-only infrastructure.

Carbon Reduction and Environmental Impact
Transitioning to a blended bio heating oil provides a measurable decrease in a facility’s environmental impact.
- Immediate Carbon Reduction: The 50% renewable biofuel ratio delivers an immediate reduction in heating-related CO2 emissions by approximately 50% (averaging ~43%) when compared to standard kerosene or gas oil.
- Directive Compliance: Formulated with a maximum sulphur content of 0.1%, Prema B50 ensures regulatory compliance with the parameters of the Medium Combustion Plant Directive.
- Particulate Emissions: The specification prevents the production of smoky emissions and significantly reduces overall local particulate matter output.
Cost Control and Operational Expenditure
For commercial operations balancing emissions targets with procurement budgets, Prema B50 Heating Oil provides a strategic financial middle ground.
- Balanced Cost Profile: The 50:50 blend provides quantified environmental benefits at a lower purchase price than 100% renewable fuels, such as HVO100 or pure bio heating oil.
- Thermal Efficiency: This high quality fuel maximises combustion efficiency and has a net calorific value of typically 43.5MJ/kg.
- Controllable Expenditure: The consistent chemical profile allows for accurate forecasting of required fuel volumes, resulting in controllable, predictable costs for commercial heating systems.
Infrastructure and Drop-In Interchangeability
Prema B50 Heating Oil is engineered for immediate integration into existing commercial boiler systems, requiring zero operational downtime.
- System Compatibility: The fuel functions as a direct drop-in replacement for systems currently operating on diesel, kerosene, 35-second oils, standard industrial heating oils.
- Zero Capital Expenditure: The transition to this blended bio heating oil does not require any costly modifications to existing burners, pumps, or feed lines.
Transitional Flexibility: Prema B50 allows facilities to start the decarbonisation process immediately without the disruption of overhauling fully functional heating equipment.
Operational Reliability and Winter Performance
Maintaining consistent thermal output during adverse weather conditions is a primary specification for industrial fuels.
- Winter Performance: The formulation maintains a Cold Filter Plugging Point (CFPP) of -12°C. This ensures fuel flow and performance remain completely unaffected by cold weather, guaranteeing consistent thermal output year-round.
- Storage Requirements: Due to its specific low-temperature stability, Prema B50 does not require heated storage infrastructure. It operates efficiently using standard, unheated outdoor tanks during UK winter conditions.
- Continuous Uptime: The product is manufactured to prevent common causes of operational failure, ensuring no downtime for continuous industrial heating processes.
FAME-Free Specification and Storage Longevity
The chemical stability of bulk fuel impacts both maintenance schedules and overall expenditure.
- FAME Content: Prema B50 is strictly 100% FAME-free (Fatty Acid Methyl Ester).
Maintenance Reduction: Manufactured from high-quality components, the absence of FAME prevents waxing, filter and line blockages, and the fouling of heat transfer surfaces.

Frequently Asked B50 Heating Oil Questions
Prema B50 is a blended commercial heating fuel consisting of 50% premium conventional heating oil and 50% renewable biofuel (HVO). It is engineered to reduce carbon emissions by approximately 50% while maintaining the performance characteristics of a standard fossil fuel.
No. Prema B50 is strictly 100% FAME-free. This specification ensures the fuel will not absorb water, develop microbial bacterial growth, or cause filter blockages during long-term storage.
No. The fuel has a Cold Filter Plugging Point of -12°C, meaning it will not wax or freeze in severe UK winter temperatures. It operates efficiently using standard, unheated outdoor storage infrastructure.
No. Prema B50 is a rebated product specified exclusively for industrial and commercial heating applications. It is strictly prohibited by law for use as a fuel in any road vehicle, motor, or machinery.
