Heating oil is a petroleum-based fuel commonly used in the UK for off-grid heating. The main types are kerosene (28-second oil), typically used for homes, and red diesel (35-second oil), mainly for agriculture and commercial machinery.
It’s mostly used in areas that are not connected to the national gas grid. Winter can be very difficult to survive in those areas. This is where heating oil comes from, and it is very helpful in keeping your house warm throughout the whole winter and also the whole year. Heating oil is known by different names throughout the world, like kerosene, 28-second oil, burning oil, and many more.
Different Types of Heating Oil
In the UK, the two most common heating oils are kerosene and red diesel. Here’s a breakdown of each:
Kerosene
Kerosene is a type of heating oil, also called 28-second oil. This oil is safe for indoor and outdoor use as it is a lasting fuel, produces a clean burn, and has a low boiling point and viscosity. Its colour is light, pale yellow or colourless, and a dye is added to make it distinguishable from other fuels. This fuel is extracted from petroleum at a high temperature between 150 and 275 degrees Celsius. It is obtained from petroleum using fractional distillation. Kerosene is a clean oil that produces less carbon monoxide during combustion. This oil can not cause fire or explosion due to its lack of fuel vapour. While this fuel is safe to touch and use, inhaling it for longer periods can cause serious health issues.
The name 28-second oil refers to an experiment where kerosene’s viscosity is measured using a test for how long it takes for a 50ml oil to dip into the beaker. This also explains how diesel got its name for 35-second oil. It is a lighter fuel oil that is used for indoor heating.
Red Diesel
Red diesel is also known as gas oil, 35-second oil. This oil has the same characteristics as normal diesel, but it is dyed red and is strictly for off-road use only. The red diesel has a lower tax rate, making it cheaper compared to the white diesel price. It is most usually used by domestic or agricultural units that have mostly old boiler units and agricultural vehicles. This oil contains low sulphur, and it is heavier than kerosene.
Benefits of Using Heating Oil
Heating oil brings a lot of benefits. The following are some:
- Its main benefit is that it won’t burn in its liquid form. The oil needs a higher temperature to become combustible. The heating systems are equipped with an emergency shutdown in case of any hazardous emergencies or other events that can cause fire.
- Nowadays, heating oil has evolved, and more refined oils are in production. This makes the heating oil more efficient and safer for use. This lets the heating oil burn for more time, saving a lot of resources and costs.
- It costs less to have an oil-based heating system unit as compared to electric heaters. The heating oil is more affordable and efficient in the long run, which keeps your indoor warm and also has no bad effect on the environment.
How to Store and Maintain Heating Oil
When storing and maintaining heating oil, below are some tips that you can consider:
- You can store your heating oil in a metal or plastic tank. You need to consider what kind of heating oil container or tank you need.
- Select a location for installing your tank. It can be installed either above or underground according to your requirements. Wherever you are installing, make sure it is away from direct sunlight and heat sources.
- After the tank is installed and heating oil has been added to the tank, make sure to inspect it from time to time to ensure there is no sign of any damage that can cause potential risk later.
- When adding fuel, make sure you wear gloves and goggles, and you don’t spill the oil and pollute the environment.
- Always consult an expert for a routine check-up of the tank to ensure the safety and peace of mind.
