The Proactive Choice: Should You Use Heating Oil Additives?
Maximising Fuel Performance with Additives
Heating oil additives are chemical treatments that are added directly to your kerosene storage tank. While modern heating oil is a high-quality fuel, additives are designed to enhance its performance, protect your heating system, and potentially save you money in the long run.
Is Modern Kerosene Not Good Enough?
Standard kerosene (C2) is refined to a very high standard. However, once it leaves the refinery, it is subject to several factors that can affect its performance:
- Storage Conditions: Temperature changes inside your tank can lead to condensation (water) forming.
- Oxidisation: Over time, oil naturally degrades, forming microscopic particles.
- System Aging: Older boilers and tanks may have accumulated debris that standard fuel can't handle.
The Key Benefits of Using Additives
Most homeowners choose to use a multi-purpose premium additive to gain these advantages:
1. Reducing Sludge and Carbon Build-up Additives contain detergents that help break down the "sludge" that naturally forms at the bottom of oil tanks. This significantly reduces the risk of the sludge being drawn into your fuel lines and blocking your filters or boiler nozzle.
2. Improved Fuel Stability If you tend to use your heating sparingly (perhaps you have a well-insulated home or use a secondary heat source), fuel can sit in your tank for a long time. Additives act as stabilizers, preventing the fuel from degrading and ensuring it burns cleanly when you finally need it.
3. Higher Efficiency and Lower Emissions By ensuring a more complete and cleaner burn, additives help reduce the amount of soot that builds up on your boiler's internal components. A cleaner boiler is a more efficient boiler, meaning you get more heat for every litre of oil you buy.
4. Water Management In the winter, small amounts of water in your fuel lines can freeze, causing a lockout. Some additives are designed to safely "absorb" or disperse small amounts of moisture, preventing ice blockages and inhibiting the growth of "fuel bugs" (bacteria that thrive in the interface between oil and water).
Should You Use Them?
While additives are not strictly mandatory, many oil technicians recommend them—especially for systems with outdoor tanks or older boilers. They are a relatively low-cost way to:
- Reduce the frequency of emergency call-outs.
- Keep your boiler running at peak efficiency between services.
- Protect your storage tank from internal corrosion.
Pro Tip: If you decide to use an additive, it’s best to add it to the tank just before a delivery. The force of the new oil being pumped in will ensure the additive is thoroughly mixed throughout the fuel.
Conclusion: Heating oil additives are a proactive choice for homeowners who want to ensure their system remains as reliable and efficient as possible. It's a small investment that often pays for itself through reduced maintenance costs.
