Oil Updates

Bunded Tanks

OFTEC and FPS (Federation of Oil Suppliers) are working closely together to finalise the launch of a new campaign to encourage oil users to replace ageing or damaged tanks. It is estimated that there are 400,000 + single skin domestic tanks still in use which are more than 20 years old.  

There will be three elements to the campaign:
  • New warning tags and stickers - issued to both OFTEC technicians and FPS members - with advice as to when these must be attached to a tank deemed “at risk”. Also a user-friendly postcard will be left with the homeowner telling them how to  get advice on tank replacement from FPS members and OFTEC technicians.
  • A new section of the Oilsave website – called “tank awareness” which will give information to the homeowner; to the OFTEC technician; and to fuel delivery drivers about action to be taken when warning tags or stickers must be, or have been, have been applied to tanks
  • A PR campaign initially aimed at rural local papers and radio stations urging home owners to have their oil tanks inspected, and to replace ones at risk.
This reinforces a significant change in BS5410-1 2014 that states:

"All new and replacement oil storage tanks should be installed within secondary containment i.e. the tank should be located within a masonry or concrete bund constructed in accordance with 7.4.2 [of BS5410-1] , or should be of the integrally bunded type"

Adventitious Air

Another significant change to BS5410-1 2014 is that the allowance for Adventitious Air has been removed. Previously an allowance of 5kw (27.5cm2) was allowed for an open flued appliance in a room. This meant that an appliance requiring 150cm2 only needed a vent supplying 122.5cm2.

BS5410-1 2014 has removed this allowance, and therefore in the above example the full 150cm2 vent would need to be installed.

If you encounter an appliance that was installed prior to Dec 14 that is operating satisfactorily, even though the ventilation is undersized according to the current standard, you can leave it in operation without any further work. Appliances installed after Dec 14 should have the correct ventilation installed.


With increased pressure on energy efficiency (ErP ratings) Firebird have designed an "A" rated boiler with reduced NOx levels. The Boiler comprises of the RDB Blu Low NOx burner which delivers clean soot free combustion.

The burner atomises the heating oil before being mixed with pre-warmed air. This mixture is then ignited and the hot combustion gasses recirculated through the blast tube in a specially designed slot. This process produces a blue flame and reduced NOx levels.

More information on the Firebird Enviroblue C20 can be found on their website.
