Comparing Industrial Heating Oils: Product Guide and Specification Analysis

Prema 35 Industrial Heating Oil

Prema 35 operates as a direct drop-in replacement for standard diesel and standard gas oil.

• Primary Benefit: It delivers the exact same calorific value as standard diesel at a lower purchase price, acting as a rebated fuel to immediately control procurement costs.
• Key Differences: Unlike variable gas oils, Prema 35 is strictly optimised for heating applications. It contains a multifunctional additive that provides corrosion protection and maintains system cleanliness, effectively preventing long-term maintenance expenditure.

Suitability: Optimal for facilities requiring high thermal output with zero capital expenditure on infrastructure modifications.

Prema B50 Heating Oil

This product is a 50:50 blend of premium conventional heating oil and renewable Hydrotreated Vegetable Oil (HVO).

• Primary Benefit: It provides a strategic financial middle ground, delivering typically ~43% to 50% reduction in carbon emissions.
• Key Differences: Prema B50 requires zero operational downtime or infrastructure upgrades. It maintains a CFPP of -12°C and is 100% FAME-free, ensuring long-term storage stability without microbial contamination.
• Suitability: Specified for commercial operators seeking a practical, cost-controlled first step toward net-zero targets without overhauling existing unheated boiler systems.

Prema HVO100 Heating Oil

Prema HVO100 is a 100% renewable, fossil-free Hydrotreated Vegetable Oil manufactured to replace diesel.

• Primary Benefit: It achieves typically a 90% net reduction in CO2 emissions.
• Key Differences: The fuel functions as the ultimate drop-in replacement with superior physical properties. It boasts an extreme low-temperature performance (remaining fluid down to -30°C) and provides a shelf-life of up to 10 years without degradation.
• Suitability: Designed for facilities requiring maximum greenhouse gas reduction from unheated outdoor storage tanks, including intermittent heating systems and backup generators.

Prema Bio Heating Oil

Prema Bio Heating Oil is an industrial-grade, renewable fuel for high-volume commercial operations.

• Primary Benefit: It provides the carbon-saving performance of premium renewable fuels (over 90% reduction) at a substantially lower operational cost. It does not attract excise duty, creating a rapid return on investment for large users.
• Key Differences: Unlike Prema 35, B50, or HVO100, this fuel has a Pour Point of 5°C to 10°C. Consequently, it requires heated storage tanks and a heated ring main to the burner to maintain optimal viscosity for combustion.
• Suitability: Specifically targeted at large industrial sites already equipped with heated Heavy Fuel Oil (HFO) infrastructure, or high-volume facilities intending to install heated storage to unlock long-term cost leadership.
