Oil Tank

Are you about to install an oil central heating system in your home? Then you’ll also need to fit an external oil tank for the fuel. Continue reading to learn about how domestic oil tanks work as well as costs and maintenance tips.

How much does an oil tank cost?

With oil central heating, installing an oil tank is a necessary expense. On top of the network of oil-fired boiler, radiators, and pipes, you’ll need to place a separate oil storage tank. Domestic oil tanks can either be placed indoors, outdoors, or underground.

The price of a heating oil tank will vary based on where it is installed, the capacity, as well as the type. An oil tank will either be single-skinned, double-skinned, or bunded. A detailed explanation of these types will follow in the next section.

Oil tank details

Domestic oil tanks are storage containers for the oil that powers your heating. When installing a central heating oil tank, you have to make a few choices. First is the location of the tank: inside, outside, or underground. The second is the material: plastic or steel. And the third is the type: single skinned, double skinned, or bunded.

Heating oil tank types differ on the number of outer layers of the tank, and the level of protection against leaks.

  • Single skinned oil tank – There is only one outer layer, hence the name. Single skin tanks are most suitable for homes in areas that are considered to be environmentally stable. These tend to be cheaper but don’t provide a high level of protection.
  • Double skinned oil tank – A tank with two layers, providing another level of protection against leaks. In some cases, a double skin tank is sufficient to meet safety regulations.
  • Bunded oil tank – This is basically a tank sitting inside another, larger tank. There is space between the two tanks to prevent any oil from leaking out. This is the safest option and tend to be more expensive than the other types.

Usually, single and double skinned tanks must have a bund around the inner compartment. This is mandatory for areas that are environmentally sensitive according to a risk assessment. If the place that will house your oil tank is sufficiently protected from external elements, then bunded oil tanks might not be mandatory.

However, minimising the risk of oil spills takes priority. Usually, if there is a river, well, or other source of water near the tank, it must be bunded.

Oil tank installations must follow the building regulations of your area. Additionally, any work done involving oil tanks must be completed by an OFTEC registered engineer. Ask a certified heating professional for more details on these requirements.

Supplier filling an oil tank

How to keep your heating running

With a central heating system that runs on oil, you’ll need to arrange for deliveries on a regular basis. This involves searching around for oil suppliers who service your area. There are several factors that influence the actual amount of oil you need. These are:

  • The size of your home
  • The efficiency of your boiler
  • The efficiency of your home
  • Your heating and hot water demand

When ordering a delivery for the first time, you’ll need to know the size of your tank. This way, you won’t order too little or too much oil. Also, you should provide detailed delivery instructions to the suppliers. This will make the whole process go smoothly—the suppliers will be able to locate your home and tank easily.

To make sure that your central heating has enough fuel, it’s important that you keep track of how much oil is in your tank. Modern tank models have an electronic monitoring system that detects when oil levels drop to a certain level and notify you. These remove the need for a traditional gauge on the oil tank.

When looking for suppliers in your area, take some time to compare their prices. Get at least 3 prices from oil supply companies to find the best price that fits your needs. This is also a great opportunity to compare their delivery schedules and services.

Checking up on your oil tank

Similar to your boiler, you need to regularly check on your oil tank. Inspect your tank at least once a month, as well as when you place an order for an oil delivery. What are the things you should look for?

  • Check that the tank is not covered in vegetation or fallen leaves
  • Check that the tank and base is not cracking or sloping
  • Examine all parts of the tank for cracking or rust
  • Look for signs of damage on piping and valves
  • Check nearby plants for signs of die-back
  • Clear the nearby area of liquid or rubbish
  • Make sure that the secondary tank (bund) is empty
  • Ensure that all entry points to the tank are fully closed

Also, an OFTEC registered professional should inspect the oil tank once a year. Usually, this is scheduled together with your annual boiler servicing.
