Navien LCB700 Blue Flame Combi Internal BoilerWhat is an oil boiler?

An oil boiler provides central heating and domestic hot water to a property by using oil as a fuel source. Oil boilers are an ideal solution for properties not connected to the mains gas grid. The oil utilised by this type of boiler is stored in a tank located at the property.

Helping you to choose the most suitable oil boiler 

As a company, we only partner with manufacturers that offer reliable and efficient oil boilers. As an independent boiler installation company, we will only ever recommend a boiler that meets the needs of your property and household. We pride ourselves on listening to your requirements and assessing your property to provide the most suitable solution. 

When recommending a boiler we will guide you through the following considerations:

  • The kW output of the boiler – this determines the oil boiler’s ability to cope with the heating and hot water needs of your household
  • The type of oil boiler you require – we offer oil combi boilers, oil system boilers, and oil conventional boilers
  • Components used in the oil boiler – we will never recommend a boiler that uses an aluminium heat exchanger or plastic parts
  • Ease of installation – reducing installation time will save you money
  • Parts availability – all of the boilers that we recommend use parts that are available from plumbing merchants across the UK
  • Our service level agreement with the manufacturer – we are recommended installers for a number of manufacturers, this brings with it a whole host of benefits
  • Terms and conditions of the warranty – we will guide you through exactly what the warranty does and doesn’t cover
  • Warranty period – we aim to recommend you a boiler with a lengthy warranty period

Oil boiler tanks

To use an oil boiler at your property you will require an oil storage tank. There are three main types of oil boiler tanks:

  • Single Skin: suitable for installation in a reinforced concrete or masonry bund
  • Double Skin: predominantly used for commercial underground applications 
  • Integrally Bunded: used above ground and within buildings

Oil storage tanks are usually made of steel or polyethylene. They can be supplied in a range of shapes and sizes to suit the site requirements. If you don’t already have an oil storage tank, we are able to assist you in choosing the most suitable type and size for your property.

For most homes, an oil storage tank between 1000-2500L will be suitable. Oil storage tanks are usually fitted with a device that will warn you when the tank contains low levels of oil. 

When installing an oil storage tank, it is important that the regulations are followed for safety and environmental reasons. As oil engineers with vast experience, this is something that we will assist you with.
