Although heating oil tanks are less common these days than they used to be, they continue to play a vital role in keeping homes warm and cosy in many rural areas.
Perhaps you’re taking on a period property with an oil tank or just curious about how they work. Either way, here’s a simple beginner’s guide to oil tanks and how they work.
What is an oil tank?
An oil tank is a storage container designed to hold a supply of heating oil, which powers heating systems in homes and businesses. The tank stores the oil until it is required, releasing the fuel to a burner or furnace in response to signals from the thermostat. This generates heat, which is distributed throughout the building via a central heating system.
Oil tanks are commonly found in areas with limited access to natural gas infrastructure, such as rural regions. In these locations, heating oil tanks offer a practical and cost-effective solution for keeping homes warm during colder seasons. They are kept outside, usually in gardens and come in various sizes to accommodate the needs of different households.
Different types of oil tanks
Depending on needs and requirements, there are a few different types of oil tanks on the market. Aside from sizes and capacity (ranging from 650 litres to as much as 2,500 litres), they also come in different materials.
Typically, you’ll find plastic or steel oil tanks available. Steel tanks usually have a longer lifespan (around 20-30 years) than plastic tanks if looked after correctly, as they are less prone to physical damage. They can be single-skinned or double-skinned (also known as bunded oil tanks) for extra protection.
Plastic tanks are typically constructed from polyethene, making them lightweight and resistant to rust, making them ideal for outdoor environments. Their lifespan sits at around 15 to 20 years, so slightly shorter than steel tanks as they can become brittle over time due to UV exposure and extreme temperatures. Most are single-skinned but may include bunded designs for added safety.
Cost of oil tanks
The cost of an oil tank ranges anywhere from £500 to £2,000, depending on the size and material. To have a tank installed and set up, you’re looking at anywhere between £1,000 and £1,500 and this includes preparing a stable base, fitting the tank and connecting it to the heating system.
Once a heating oil tank is set up and ready to go, there are some ongoing costs to consider. These include purchasing heating oil, delivery charges and the cost of maintenance. This will depend on how much heating oil you need to use, the company you purchase oil from and your location.
Owning an oil tank provides numerous benefits, including energy independence and the flexibility to manage your heating needs, particularly in areas without access to natural gas. It allows for cost control through bulk oil purchases and offers compatibility with various heating systems.
It does also, of course, come with responsibilities. Regular maintenance, inspections and cleaning are essential to prevent issues and prolong the lifespan. All in all, heating oil tanks are a safe and cost-effective heating choice for a home.
