Fireproof Oil Tanks – Answers to your Burning Questions

It makes sense that tanks with adequate fire protection are essential for storing any liquid that has the potential to ignite during storage.

Our fireproof oil tanks are manufactured and fully tested to ensure the safe storage of heating oil in line with building control regulations. Peace of mind for tank installers and their customers.

What are the Benefits of Fireproof Tanks?

Of course, a fireproof tank has obvious safety benefits, but it goes further than that when it comes to installation…
Under building regulations, conventional heating oil storage tanks are required to be installed in an isolated location with strict ‘fire separation distances’ ensuring a minimum distance from other structures. This can be quite restrictive when planning an installation, especially if outdoor space or minimising visual impact is an issue.

Choosing a fireproof oil tank means that you have much freedom concerning the site of installation. Fireproof tanks can be sited closer to recognised fire hazards than conventional tanks. This often means that the tank can be located in a more ‘out of the way’ location to keep your garden view free of ‘unsightly heating equipment’ – although we love all our tanks, we’re the first to admit that oil tanks are never going to win beauty prizes!

With more scope on the placement, including a relaxation on minimum distances from windows, doors and garden boundaries, it’s easier to tuck your oil tank away behind the garden shed! That’s more good news when you’re considering visual impact or saving outdoor space.

Installing a conventional tank within close proximity to buildings often means installing a costly fire screen wall with it… another garden feature you can probably do without. Due to the use of inbuilt fireproof material combined with a robust bund in a fireproof tank, a fire screen wall isn’t needed.

Are Fireproof OilTanks OFTEC approved?

This is a question we’re often asked. Fireproof tanks are not OFTEC approved. But far from that causing a headache for our installers, it just means that the tank can be signed off by Building Control.

Remember, it’s still mandatory that OFTEC’s regulations for the siting of your tank are followed. Your oil tank must be a minimum of:

  • 1.8m away from non-fire rated eaves of a building
  • 1.8m away from a non-fire rated building or structure (e.g. garden sheds)
  • 1.8m away from openings (such as doors or windows) in a fire-rated building or structure (e.g. brick-built house/garage)
  • 1.8m away from liquid fuel appliance flue terminals
  • 760mm away from a non-fire rated boundary, such as a wooden boundary fence
  • 600mm away from screening (e.g. trellis and foliage) that does not form part of the boundary.

If you’re in any doubt or need advice – always consult an OFTEC registered installer.

What about the Atlantis Tanks Range of Fireproof Oil Tanks?

Fireproof oil tanks are clearly a good choice for many customers and are becoming increasingly popular. That’s why we stock a range of both plastic and steel tanks manufactured to comply with the relevant fireproofing standards. Take a look at the range on our website:

Why Atlantis Tanks’ Fireproof Tanks are Market Leading


Whereas many tanks on the market are double-skinned, our fireproof tanks are triple-skinned. This is because in a double-skinned tank, the bund isn’t protected from fire, only the inner tank benefits from the protection. Three skins mean the bund as well as the inner tank are protected.

Non-absorbent Insulation

The wool-type insulation used in some tanks on the market is absorbent. This means that, should the inner tank leak for any reason, the insulation would absorb that kerosene. In effect, it would no longer act as fire barrier. The visual examination to check if this problem has occurred is tricky and involves removing all the material to see if it has absorbed any liquid. Trust us, it’s no an easy task but there really is no other way of doing it.

Our special non-absorbent insulation is a game-changer in this respect. It doesn’t need to be visually inspected. It’s not stored inside the bund, so in the unlikely event of the inner tank leaking into the bund, the liquid wouldn’t come into contact with the insulation.
