Oil fired central heating boilers burn kerosene or heating oil. This is the most popular system where mains gas is not available.

An oil-fuelled central heating system works in the same way as a gas-powered central heating system.


There are now high efficiency combi and heat-only oil boilers available on the market. 


Oil combi boilers have internal hot water tanks to supply hot water. Whereas gas combi boilers have what’s called on-demand hot water.

  • Oil combi boilers are highly energy efficient, and you can save a lot of fuel by heating up water on demand.

  • The running costs of oil combi boilers is usually much, much lower than other types of oil and some LPG boilers.

  • Oil is a more efficient fuel than gas and LPG, so every unit of energy spent gives a much better return.

  • Newer oil boilers are condensing boilers, running at an efficiency of 90% and above, compared with 60% for older boilers.
