Oil Fired Combi Boilers Explained
An oil-fired combi boiler system is a key alternative for the estimated 4 million houses in the UK that are not connected to the gas network. Oil-fired combi boilers are suitable for those who live outside the city without access to gas and electricity supplies.
As an alternative to gas heating, oil combi boilers allow you to keep fuel stored near your property and top up the unit according to your need. Modern oil-fired combi boilers can be very energy efficient (up to 95%) and there are many ‘A’ rated models on the market as well as other types of boilers.

How Does an Oil Fired Combi Boiler Work?
An oil combination boiler system works in a similar way to its gas-powered alternative, using an oil-fired boiler to heat water, which supplies the central heating via radiators and hot water through the taps in your household.
The main distinction between the two is that the oil fired boiler requires a constant oil supply, delivered and stored in a tank. The majority of oil-fired combination boilers have an internal hot water store to supply domestic hot water rather than immediate heating which is more common for gas boilers.
The popularity of oil-fired combi boilers is expected to rise in the UK since they have numerous advantages over other types of heating systems.
- Oil fired boilers are exceptionally energy efficient and save a lot of fuel by heating up water only on demand.
- The running cost of combi boilers (including oil fired) is considerably lower than with other types of boilers.
- Oil is a more efficient fuel than gas, so it gives a good return on every unit of energy.
- Typically, a new oil-fired boiler will have an efficiency of 92% to 95% compared with 60% to 70% in case of older systems.
- It is fair to say that oil-fired combi boilers are slightly slower to provide hot water than gas combi boilers, thus more suitable for smaller properties.
- Similarly to the price of gas, oil price continues to steadily rise.
- A household combi oil boiler requires periodic maintenance in order to guarantee its safety since a problem in any oil boiler can be dangerous.
The Cost of Oil Fired Combi Boilers
Oil combination boilers prices normally vary from £1,000 to £2,800, even though the final price of the boiler depends on the attributes, efficiency, size, quality, environmental standards and compliance. In the boiler system, the oil combination boiler itself is the less expensive feature and some funding can be provided by the government if you qualify.
The price of a new boiler system includes the cost of features, pipes, call-out fees, maintenance charges and insurance. The cost of standard oil combi boiler models according to various combi boiler suppliers and retailers is provided in the following list of figures:
- Eurocal: £1,350-1,900
- Warmflow: £1,700-1,950
- Grant Vortex: £1,800-2,000
- Firebird: £1,850-2,150
- Worcester Greenstar: £2,000-2,300
There is an additional expenditure on supplying your oil central heating boiler regularly with oil. Almost all UK oil fired heating systems use 28 sec oil, which is sometimes known as kerosene. This fuel burns cleaner than heavier oil products such as gas oil, which is also known as 35 sec heating oil.
The annual domestic oil demand is approximately between 600 and 1,750 liters. Oil can be bought separately, costing around £220-280 for 500 liters or can be purchased as a part of the service program, which is included in the boiler system maintenance.
Are Oil Fired Combi Boilers Good for the Environment?
A modern, high-efficiency oil-fired boiler presents an environmentally conscious alternative, especially for houses that are not connected to the gas main. As with all types of heating systems, regular maintenance will help the boiler burn more efficiently. Also, during the warmer summer and autumn months, most oil boilers work well with solar water heating, which can provide most of your domestic hot water in the daylight hours.
