The size of heating oil tank you need depends on your home, heating usage, available space and how often you want to order fuel. Most domestic oil tanks are designed to hold enough heating oil to keep the home running for a reasonable period between deliveries.
Choosing the right size helps you avoid ordering too often or running low during winter.
Common Domestic Tank Sizes
Domestic heating oil tanks come in different sizes.
Common tank sizes include:
- 1,000 litres
- 1,200 litres
- 1,350 litres
- 1,500 litres
- 2,500 litres
The right size depends on your property and how much oil you use.
What Affects Tank Size?
You may need a larger tank if:
- Your home is large
- You use heating oil for hot water
- Your property is poorly insulated
- Your boiler uses a lot of fuel
- You live in a rural or hard-to-reach area
- You want fewer deliveries each year
- Your household uses heating throughout the day
Smaller homes with good insulation may not need as much storage.
How Much Space Do I Need?
Your tank must be installed in a safe and suitable location. It needs enough space around it for access, inspection and delivery.
Before choosing a tank, think about:
- The size of your garden or outdoor space
- Delivery tanker access
- Distance from buildings and boundaries
- Ground conditions
- The tank base
- Safety and building requirements
A qualified tank installer can advise on the correct location.
Should I Choose a Larger Tank?
A larger tank can mean fewer deliveries and more flexibility when ordering. However, it must be suitable for your property and installed correctly.
Do not choose a tank based only on capacity. Safety, access and regulations are just as important.
When Should I Replace My Tank?
You may need a new tank if your current one is:
- Cracked
- Rusty
- Bulging
- Leaking
- Unstable
- Too small for your usage
- Difficult to access safely
