Heating Oil Additives

Do you need to use additives in your heating oil? We are asked this question regularly so here is a quick guide on the use of additives.

Heating Oil Additives are used to increase the overall efficiency of your home heating oil. They do this by protecting your boiler from sludge build up and increase the life time of your oil tank. The most popular heating oil additives are premium additive & Cooker (Aga) Additive. We supply EXOCET additives, which are available to add to your order at the checkout. Read more about these products below.

Cooker (Aga) Additive

Cooker (Aga) Additive

Exocet Cooker Additive acts to reduce the Char Value of the fuel, improving its combustion performance and maintaining a clean burner for longer.

The char value is measured by the amount of charred oil deposition left on the wick after burning the fuel in a standard wick lamp at a standard rate for 24 hours. The Char Value of heating oil is often supplied at 16-30mg/kg. The British standard recommendation is a maximum of 20mg/kg. When the char value is greater than this it has a negative impact on the performance of range cookers (e.g. AGAs, Rayburns, Waterford-Stanleys, etc). This is due to a carbon build-up around the burner. This results is variable heat output and poor controllability.

By using a heating oil additive, your cooker & tank will benefit from;

  • A lower char value
  • Reduced build up of carbon deposits and soot
  • Inhibits growth of deposits in fuel tank
  • Minimises the potential for fuel tank corrosion
  • Increases the fuel shelf life
  • Reduces service problems

You will benefit if;

  • You use a range cooker (AGA) on kerosene
  • When your fuel storage tank has a low turnover
  • Your burner continually ‘cokes’ up and/or fuel pipe blocks

A 200ml bottle treats 1,000 litres of heating oil.

Premium Oil Additive

Premium Oil Additive

Exocet Premium Additive guards against fuel degradation, the corrosion of metal storage tanks and associated pipework, the adverse effects of fuel interaction with copper containing fittings and pipework and serves to inhibit the build of deposits in storage tanks.

By using a premium heating oil additive, you will benefit from;

  • Lower carbon emissions
  • Stabilised fuel which increases its shelf life
  • Inhibited sludge formation
  • Reduced deposit build up around nozzles and on heat exchanger surfaces
  • Reduced service problems
  • Improved system efficiency

You will benefit if;

  • Your fuel filters plug
  • Your burner jets foul quickly
  • You get excessive soot deposits in the heat exchange chamber

A 200ml bottle treats 1,000 litres of heating oil.
