Vapourising burners as found in Aga, Rayburn and Range Master cookers are very sensitive to carbon and soot build-up, it is not unknown for them to soot up every 4-6 weeks. Hydra Heating Oil Additive prevents these deposits from building up, keeping the burners free of soot between services.

Dilution rate: 1:2500 i.e. 100ml treats 250 litres of fuel.

Refuelling Dose to Protect Clean Fuel System
Dilution rate: 1:5000 i.e. 100 ml of treats 500 litres of heating oil. Treat oil tanks every time they are topped up.


Most heating boilers are of a pressure jet design which use precise fuel metering through narrow shaped spray channels. Injector deposits mean reduced fuel flow. Whereas 100% clean injectors give optimal fuel spray pattern. Each finely dispersed particle of fuel is surrounded by many molecules of air (20% oxygen) ensuring a more complete burn. Which in turn gives you better fuel economy, reduced emissions and improved boiler durability.


Hydra Heating Oil Additive contains heavy duty detergents prevents the formation of and removes existing deposits from burners and injectors and heat exchangers. In the oil tank safely dissolves years of corrosive sludge back into the fuel where it's burned away. While creating a protective barrier to stop the sludge gunk from coming back!


Using Hydra Heating Oil Additive upgrades standard heating oil to a premium standard for heating oil. The boiler fires easier with reduced soot and fuel consumption. Better combustion means less deposits on burners and heat exchanger.


All our products are manufactured to the highest international specifications at our UK plant. Which is accredited to ISO 9001:2008, ISO 14001:2004 and OHSAS 18001:2007 this ensures all fuel standards are adhered to.

Fast delivery, package OK. If it's as good as Hydra's other products I've used it will be excellent. Waiting for next tank refill to use it

Best Ever Used
Tuesday, 17 January 2017  | 

I have had oil fired boilers for over 40 years now. During that time I have tried quite a few of the additives on the market, none of which were 100% successful. However I have now been using the Hydra Heating Oil Additive for over 2 years.
We buy our oil from different suppliers, as the oil prices keep changing, the company that was cheapest last time is often now the most expensive.
Also the quality of the heating oil we receive varies a lot. Without adding this product, itís guaranteed that my boiler shuts down after every oil delivery.
I always put in a bottle of this before the tank is filled and I have yet to have any of the issues I've had in the past with a new delivery clogging the filter.
I also service my boiler each year so I have seen the condition of the burners before and after using this product - the burners are definitely a lot cleaner since I started using this.
I'm not sure of the science behind the product but as a heating oil additive itís the best Iíve ever used.

Great Product.

My Aga burner was choking up with soot every 4-6 weeks, since using this product my Aga only needs servicing once per year doesn't work properly without it.

Been using this product for a couple years now. I have no idea how such a small 250ml bottle can treat 1,500 litres of fuel but it works. My old filter looks just as clean as the day I installed it. Highly recommended!

You Gotta Have This
Tuesday, 15 December 2015  | 

I have an old fuel oil furnace. At the beginning of the heating season, it was spitting and spluttering and I kept hitting the reset button. Instead of calling a repair man, I looked on the internet and found the Hydra Heating Oil Additive which was much cheaper than calling out the service man, I added it to my half full tank
stirred with a broom and boy what a difference it made.

Hydra Heating Oil Additive

Ques : Is this use for putting straight into home heating oil tank which feeds the central heating boiler only ?

Ans. Yes, Add Hydra heating oil additive straight in to the oil tank in correct dilution then top up with new fuel. Please make sure Fuel tanks being treated should be at least 10% full.
