Oil AGA Cooker or Rayburn Cooker Problems?

After seeing an article in yesterdays Telegraph on the effect the change in the content of oil fuel is having on the running of AGA cookers I thought I re post my post from a few months ago,  problems of oil AGA cookers . As the article in the Telegraph says the problems seem to be localised to some regions and it doesn't appear to be a National problem. Maybe this is to do with the way kerosene is stored – perhaps the new stuff hasn't been started to be used in most areas.

Anyway here is an edited update version of my previous post.

On Friday 20th February 2009 there was a radio broadcast on BBC Radio 4 (sorry it doesn't appear to be available for download) about the effect changes to Kerosene and how it was affecting oil AGA cooker and Rayburn cookers. Of course this would apply to any range cooker that burns oil such as Stanley, Redfyre, Esse, Sandyford etc.If you have been having efficiency problems with your oil AGA Cooker, Rayburn Cooker or oil home heating boiler in last six months or so, say it's being smoking or going cold or just not going at all the problem is probably the properties of the kerosene you are using. Heating oil suppliers have been forced to reduce the polluting sulphur in domestic heating oil from 0.2% to 0.1% with effect from the 1st January 2008 to meet EU regulations. This requirement is contained within the 1999 EU Sulphur Content of Liquid Fuel Directives. In England and Wales the Directive is being implemented under The Sulphur Content of Liquid Fuels

(England and Wales) Regulations 2007. See Kerosene Sulphur Change The resulting product has a much higher ‘char value’ than before and this will cause your oil AGA cooker to coke up quicker and more often. It may have taken a while for you to notice this and you've probably been living with it blaming it on other things or you've being using the old kerosene stored in your oil your tank and have only bought and used the new stuff more recently.Suppliers have no choice but to provide this new formula kerosene. New AGA cookers work OK with the new oil and a replacement burner is available at a cost to owners of oil fired AGA I'm not sure about Stanley cookers, Esse cookers, Redfyre cookers, Rayburn cookers, Sandyford cookers etc. However if you have an old converted solid fuel AGA cooker  (not sure about Rayburn cookers) the new burner does not fit and I've heard that the new burners will cost a bomb. I'd expect these to be the ones with Dons conversion kits. I think because of these the older 'standard' AGA cookers will die out as they will be very difficult to live with.The older AGA cookers that have been converted from solid fuel have always been a nightmare anyway regularly coking up, yellow flame, smoking, going cold when loaded etc. This new fuel with make things worse.My advice if you have an AGA cooker that was once a solid fuel one but  has now been converted and you are having serious problems with it is to fit a new AGA pressure jet burner unit from www.tradcookers.co.uk. You may have to buy a new AGA off ebay and then get the unit installed in that one.

Or you can get 13 amp conversion kits and get one of those fitted. You will probably have to lose the boiler, if you have one, though.

  • We supply a fuel additive which acts as a “surfactant” on the kerosene effectively giving better separation of the hydrocarbons in the fuel. This has a result of getting better fuel atomisation at the wick, meaning the fuel burns more completely which reduces the carbon residues. This in turn means that the fuel system stays carbon free for much longer.

  • Nigel, I sure your solution to the oil AGA problems will be welcomed by those people who are having problems with their oil AGAs. It certainly is a cheaper solution than replacing the AGA cooker with something else. I have oil AGA owning clients who are using additives and they say that it really helping with the carbonisation problem of their AGAs. So thank you.

  • No problem Graham I sincerely hope it helps more people with problems in their oil fired cooker or even boiler. Its a highly concentrated product so you only need a tiny amount 1:5000 to treat the fuel, and because its a detergent/surfactant it has the additional benefit of breaking down the sludge and impurities that have built up over time – effectively cleaning the entire system from the tank to the cooker. Also, because it basically works by helping the fuel burn better (less waste product) your fuel goes that little bit further too – which means it can even save you money on your fuel bill long term !

    If anyone has any questions about additives – especially Aderco 5000 I am more than happy to help.

  • Hi Nigel, Thank you for this, it looks fabulous stuff. If I still had my oil AGA (I now have a 30 Amp Electric One) I’d be rushing to your door. I can remember those cold Christmas days when the AGA with all the cooking just gave up the ghost and went cold, all because of carbonisation on the wick. So this stuff will help a lot of oil AGA owners get a better performing AGA.
