FAQs

Why do I need to use an OFTEC registered Technician?

Using an OFTEC registered technician ensures all work is carried out to the relevant standards and that you are kept up to date with any changes in legislation.

Do all oil tanks need to be bunded?

For commercial situations all storage tanks over 200 litres capacity need to have secondary containment or be bunded.  Not all domestic oil tanks need to be bunded however.  When an OFTEC technician quotes for replacing/installing your tank they will carry out an OFTEC TI/133D risk assessment to determine if you are legally required to have a bunded tank fitted. 

How do you dispose of old tanks?

Use a company that is licensed by the Environment Agency as a waste carrier, which means they can legally transport the tank to a licensed waste disposal site.  There are a number of licensed sites and they will need to use a ‘duty of care’ paperwork to ensure compliance with the waste regulations. 

Do I need to run the fuel in my existing tank down,before it can be changed?

No, in fact many installers prefer you to have at least 500 litres of fuel in your old tank as this ensures they can bleed through the pipe work to the boiler allowing them to check the connections. If you run the tank right down, sludge might also be drawn into the pipe work and pump on the boiler, resulting in costly repair bills. 

If my old tank starts to leak before it is changed what should I do?

Call us immediately on 020 8914 8914 (24 hours) and we will arrange for someone to pump it out. We will also give you advice on how to stem the flow to minimize pollution. 

What is a Single Skin Tank?

A Single Skin Oil Tank consists of a single container in which fuel is stored. Unlike Bunded Oil Tanks and Bunded Fuel Tanks, Single Skin Oil Tanks incorporate no secondary containment whatsoever and in the event of a spill, a pollution incident will occur.  Single Skin Oil Tanks are not suitable for the storage of fuel at commercial, industrial or institutional premises; or at domestic installations with an installed capacity of over 2,500 litres unless installed within a suitably bunded area.  For all other installations, an Oil Tank Risk Assessment must be undertaken by a competent person prior to installation and in accordance with the requirements of OFTEC Technical Instruction Book 3.  In anticipation of future possible regulations, serious consideration should be given to fitting a Bunded Tank, even where a single skin tank may currently suffice. 

What is a Bunded Tank?

Bunded Tank  simply consists of a 'tank within a tank'.  In the event of a spillage, surplus liquid will collect in the outer tank (or 'bund'), thus averting a pollution incident.  Bunded Tanks are now required at commercial,industrial, institutional, commercial and most domestic premises. 

How close to a boundary can I place an oil storage tank?

If the oil tank has a nominal capacity of less than 3,500 litres, it should not be placed any closer than 760mm to a boundary.  This assumes that there are no flu outlets or buildings between the tank and the boundary.  Where these distances cannot be achieved, the protection measures noted in OFTEC Technical Instruction Book 3 and British Standard BS5410 must be provided by means of a 30 minute fire resistant wall which extends a minimum of 300mm above and beyond the ends of the oil tank.  For oil tanks with a nominal capacity of 3,500 litres or greater please contact your local Building Control Officer or OFTEC. 

How close to a flu outlet can I place an oil tank?

Oil tanks with a nominal capacity of less than 3,500 litres should not be placed within 1.8 meters of a flu outlet.  Where these distances cannot be achieved, the protection measures noted in OFTEC Technical Instruction Book 3 and British Standard BS5410 must be provided by means of a 30 minute fire resistant wall which extends a minimum of 300mm above and beyond the ends of the tank.  For oil tanks with a nominal capacity of 3,500 litres or greater please contact your local Building Control Officer or OFTEC. 

How close to a building can I place an oil tank?

Oil tanks with a nominal capacity not exceeding 3,500 litres should not be fitted any closer than 1.8 meters to a non fire rated (30 minutes minimum fire resistance) wall or eaves. Where these clearances cannot be achieved, the measures noted in British Standard BS5410 and OFTEC Technical Instruction Book 3 must be provided i.e. the provision of a 30 minutes (minimum) fire resistant wall which extends at least 300mm above and beyond the ends of the oil tank. It will be necessary to protect exposed eaves forming part of a roof within 1.8 meters of the top of an oil tank to provide a minimum of 30 minutes fire resistance. Cladding can be applied to the eaves in order to prevent fire from spreading to the roof.

For oil tanks with a capacity of 3,500 litre or greater, please contact your local Building Control Officer or OFTEC.

Can I place an oil tank inside a domestic garage or building?

Internal oil storage tanks should never be installed in a habitable area and if installed internally, should always be contained within an enclosed chamber. Detailed requirements exist for internal oil storage installations.  For more information contact your local Building Control Officer or OFTEC.

What materials are plastic oil tanks manufactured from?

Most tanks supplied by Alltank.co.uk are manufactured from Medium Density Polyethylene (MDPE) - a material that displays excellent chemical and impact resistance properties.

Fittings vary according to tank type and supplier. However, in general fill points are made from either coated mild or stainless steel, outlets from coated mild steel, and vent points are manufactured from plastic. All materials used in the manufacture of oil tanks supplied by Alltank.co.uk are resistant to the potentially damaging long term effects of fuel.

What are the base requirements for plastic oil tanks?

All plastic oil tanks must be installed on a flat, level and fire resistant base capable of supporting the weight of the tank when fully laden.  If concrete slabs are used they should be a minimum of 50mm thick.  The base should extend at least 300mm beyond the widest points of the tank and fully support the base of the tank in its entirety.  Piers are not suitable for this purpose and can cause irreparable damage to the tank.

Can I fit a sight gauge to a Bunded Tank?

No.  Please note however that all Alltank.co.uk oil storage tanks and many other tanks are pre-supplied with an electronic tank contents gauge, which removes the requirement for a sight gauge to be fitted.  Electronic oil level monitors can be supplied separately for all other tanks.

Are plastic oil tanks designed to protect from the damaging effects of sunlight?

Yes.  Every oil tank sold by Alltank.co.uk is manufactured from a material which incorporates UV inhibitors.  These prevent UV rays from permeating the structure of the tank, thus preventing fuel degradation. 

Are plastic oil tanks supplied by Alltank.co.uk suitable for the storage of fuel for aviation use?

No.

Are plastic oil tanks fitted with sludge valves / cocks?

No.  Today, no openings (other than the tank outlet) are permitted below the maximum level of fuel in any oil tank.  This reduces the risk of accidental spillage.  In the event that contaminants (e.g. water) need to be removed from an oil tank, they should be removed by an appropriately licensed contractor via the inspection aperture fitted to each tank. 

I have discovered the presence of water in my oil. How do I get this removed?

Please contact your local fuel distributor who will be able to provide advice on how best to remove it. 

Are plastic oil tanks suitable for use with oil fired cookers?

Yes. 

On warm days there is a slight smell of oil from my oil tank. Why?

This is perfectly normal and is simply the fuel venting through the weatherproof vent fitted to the oil tank. 

Are plastic Oil Recycling Banks / Waste Oil Tanks suitable for the disposal of petrol or any other highly flammable liquid?

No.  For advice on how to dispose of petrol and any other similarly dangerous liquids, please contact your local authority. 

What are the advantages of a Tiger Loop?

The Tiger Loop is a de-aeration device which removes air from the fuel prior to combustion. The result is a cleaner, more-efficient burn, with reduced emissions and enhanced cold weather performance.  Additionally, the Tiger Loop can permit the tank to be positioned lower than the burner and up to 30 meters away.  Therefore when connected to a pressure jet burner,  it is ideal for Top Outlet Bunded Tank installations and eliminates the need for an undesirable return line. Please note that Tiger Loops are unsuitable for use with installations incorporating a vaporising burner. 

Does a Tiger Loop require batteries or mains power?

No.

How do I prime a Tiger Loop?

The Tiger Loop is self priming.

What liquids can the Apollo and Watchman remote electronic oil tank gauges be used to monitor?

Kerosene (C1/C2), Agricultural Fuel Oil (A2), Diesel (D) and Water.

Is an Apollo fuel level monitor compatible with a Watchman / Full Stop Handheld Unit?

No.

What are the power requirements for mains powered Fuel Stations and Diesel Dispensers?

Thirteen amp, single phase mains power supply with a Residual Current Device (RCD) fitted at the connection point to the power supply. All mains electrical installations must only be undertaken by a qualified electrician and must be inspected and tested regularly in accordance with statutory requirements.

What liquids are Fuel Stations and Diesel Dispensers suitable for storing and dispensing?

Diesel (D) to British Standard BS2869. Additionally, they are also suitable for the storage and dispensing of BioDiesel with a bio-element of up to 8% concentration. 

Can I store and dispense Kerosene (C1/C2) from a Fuel Station and Diesel Dispenser?

No.  The pumps and ancillary equipment fitted to these tanks are suitable only for use with Diesel or Biodiesel, as per product specifications. Dispensing a non-approved fuel from this equipment could result in serious injury or death.

Are the flow meters fitted to Fuel Stations and Diesel Dispensers suitable for the resale of fuel?

No.

Are batteries supplied as standard with low voltage Fuel Stations and Diesel Dispensers?

No.
