A water tank with the capacity to hold 1,400 litres costs anything from around £350. However, plastic tanks can reach a capacity of around 20,000 litres costing approximately £2,000 for a basic model. Rainwater harvesting kits and mains-fed water kits cost extra.

A water tank with the capacity to hold 1,400 litres costs anything from around £350. This tank is suitable for most domestic applications. However, plastic tanks can reach a capacity of around 20,000 litres costing approximately £2,000 for a basic model. Rainwater harvesting kits and mains-fed water kits cost extra.

The lifespan of plastic water tanks depends upon the quality of the tank and the condition it’s kept in. Our water tanks are expected to last a minimum of 20 years when kept in good condition. However, we have customers still using water tanks we manufactured over 30 years ago.

Large quantities of water can be stored in plastic water tanks with a capacity from 1,350 to 20,000 litres. To reduce stagnation water should be stored out of direct sunlight and below 20°C. Where possible this water should be refreshed regularly. Calmed inlets can also be used to reduce stagnation.

Large quantities of AdBlue® can be stored in AdBlue® tanks. Our AdBlue® tanks range in capacity from 1,350 – 15,000 litres in our standard range. These are available as simple holding tanks or dispensing systems perfect for quickly filling up a company’s fleet with AdBlue®.

Large quantities of red diesel should be stored in bunded diesel tanks which comply with oil storage regulations in the UK. Our bunded diesel tanks are available in plastic and steel in capacities from 1,350 to 90,000 litres and come with or without dispensing equipment.

If diesel is kept in optimum conditions below 20°C and out of direct sunlight (this is particularly important for plastic tanks) then the degradation process of diesel can be decelerated. In these conditions diesel can be stored for up to a year without the need for additives.

Storing diesel in large quantities requires a bulk storage container such as a bunded diesel tank. Our diesel tanks are available in capacities from 1,350 litres to 90,000 litres and comply with oil storage regulations throughout the UK. Dispensing equipment is also available.

Domestic oil tanks cannot be installed inside a building unless surrounded by a fire barrier with at least 60-minute fire resistance. We manufacture oil tanks integrally fitted with a fire-resistant material. This means our tanks can be sited inside buildings without requiring additional building work.

Building regulations state that oil tanks must be installed a minimum of 1.8 meters away from a house or boundary which isn’t fire rated. However, our tanks can be fitted with a fire rated material enabling a tank installation a minimum of 300mm away from your house.

Home oil tanks for domestic properties start at around £400 for a 1,400 litre plastic single skin oil tank. However, we would always advise purchasing a bunded oil tank which offer greater protection to the environment and your property. Prices for 1,400 litre bunded oil tanks start at around £850.

Home oil tanks for domestic properties start at around £450 for a slimline 1,350 litre plastic single skin oil tank. However, we would always advise purchasing a bunded tank which offers greater protection to the environment and your property. Prices for 1,350 litre bunded oil tanks start at around £900.

Heating oil tank installations vary from about £600 for a basic installation of a small tank using an existing base. The costs increase if the installer is required to do more work such as drain and dispose of the old tank, and add a new line and trench, or make a tank base.

How long a tank of heating oil lasts depends upon how frequently it’s used, the size of the tank and the efficiency of the boiler. As a rough guide you can expect to use around 2.33 litres per hour of continuous use for home heating.

If properly maintained bunded plastic oil tanks have a lifespan of at least 20 years and bunded steel oil tanks have a lifespan of at least 30 years. This lifespan is a requirement of CE marked tanks. However, oil tanks have been known to last much longer.

Heating oil tank installations start from about £600 for a basic installation of a small tank using an existing base. The costs increase if the installer is required to drain and dispose of the old tank, add a new line and base. The tank itself will cost anything from £400.

It is not mandatory to have an oil tank installed by a professional – it can be done yourself. However, you will have to notify your local authority and a site inspector will be required to inspect and authorise the installation. The costs for this vary.

A well-maintained oil tank should have a lifespan of more than 20 years for plastic and 30 years for steel. An oil tank should only need replacing if it’s damaged or warped and cannot be repaired. The person who services your tank should be able to advise you when you need to replace an oil tank.

A ‘bund’ is a secondary container protecting the contents of the primary container. When people refer to a ‘double bunded oil tank’ they really mean a ‘bunded oil tank’ – a tank within a tank with a capacity to hold 110% of the primary tanks contents.

Bunded fuel tanks have two layers – an inner tank and an outer tank (bund) which acts as a secondary containment (a tank within a tank with a capacity to hold 110% of the primary tanks contents). The bund will capture any spills or leaks from the inner tank.

If the Tuffa FMS unit is not reading correctly, check that the sensor connected to it is sat on the floor of the tank. Also check the configuration settings on the unit.

If the above are correct please contact us for further advice.

A double skinned or twin wall tank comprises of an inner tank laid directly onto the outer tank. To obtain structural strength on the outer tank a method is to support it externally or to drill holes in the outer plate and fillet weld the inner to the outer plate filling the hole in again.

All fixed tanks must be bunded and Secondary Containment to prevent spillage is a legal requirement.

DEFRA’s guidelines state:

  • “Secondary Containment does not include “double-skinned” or “twin-walled” tanks where the tank is surrounded by a second outer skin for extra strength.”

A double skin or twin wall tank is an inferior design as it may not have the legal Secondary Containment of 110%, unless additional space has been added to the outer skin to allow for this.

Please contact our sales or technical team for more information regarding your legal obligations and compliance.

In all cases a risk assessment should be carried out by a suitable qualified engineer.

If the following apply then a bunded oil tank is to be installed:

  • Tank capacity in excess of 2500 litres
  • Tank within 10m of controlled water
  • Tank located where a spillage could run into an open drain or to a loose fitting manhole cover
  • Tank within 50m of a borehole or spring
  • Tank over hard ground or hard-surfaced ground that could enable spillage run-off to reach controlled water
  • Tank located in a position where the vent pipe outlet is not visible from the fill point
  • Tank supplying heating oil to building other than a single-family dwelling

There are a couple of possibilities.

Have you just had a fill? The fuel is above the high level set on the unit. The alarm will stop sounding once the fuel is below the level set. The alarm can be muted on the display.

Secondly, check if a bund alarm light appears – if so, please refer to Tuffa as there is product in the bund.

13 amp, however, this may be dependent on which pump you have.

If there is no display on the flowmeter the batteries will require changing. Please contact us for a replacement.

If the Watchman gauge is reading  incorrectly compared to the amount of liquid in the tank it must be recalibrated. To do this, take the Watchman from the tank to the plug-in receiver (must be plugged in) and re-pair the devices. This is done by holding the white dot on the Watchman to the black dot on the receiver for 20 seconds. This pairs the device again and should now work as previous. If still reading incorrectly please refer to office for further assistance.

If the Watchman gauge has no reading, the batteries in the sonic reading device need replacing.

Ensure the switches on the receiver are set correctly. (Refer to manual for further instructions).

Your flowmeter is out of calibration and will require recalibration. Follow the steps below to resolve:

  1. Wait for the flowmeter to be on standby (no figures displayed) then press the reset button to reset the total.
  2. Dispense a quantity of liquid into a pre measured container, and note the exact measurement in the container
  3. If the flowmeter is out of calibration it should have a different total to that dispensed in to the container.
  4. Hold the menu button until the figure on the left begins to flash.
  5. Press the reset button to alter the flashing figure between 0 -9.
  6. Press the menu button to move the flashing pointer along one.
  7. Repeat this process until the figure on the screen reads the same as what was recorded by the measuring device.
  8. When correct, hold the menu button.
  9. The flowmeter is now recalibrated.

First identify whether the pump is running i.e. sounds. Check the electrical connections are tight. If the pump is not running then the thermal overload may have tripped; this can be reset. It is located on the pump control box. Push the button once, and then try the pump again. If it continues to trip please contact us for a replacement pump.

If the pump is running then there is a potential air lock from the first fill and/or subsequent fills. To rectify, whilst the pump is running slightly undo the filter to release any air or slightly undo the connection at the nozzle. Get a container and remove the nozzle, then place the delivery hose into the container and turn on the pump to run the system through and clear the air lock. Replace the nozzle to check if the problem is resolved.

Alternatively the pump has been run dry and a replacement is required. We can supply a new pump on a next working day delivery service and have an extensive range spares and accessories. Please call our sales department on 01889 567700.

A blockage or restriction in the system may have caused a reduction in the flow rate. Inspect the filter element for a blockage, and replace if necessary.

If the Tuffa FMS unit is not reading correctly, check that the sensor connected to it is sat on the floor of the tank. Also check the configuration settings on the unit.
