Most Efficient Oil Boilers

Looking for the most efficient oil boilers?

Are you looking for a new oil boiler? Do you find yourself confused about what is the most efficient oil boiler? Are you looking for a long warranty boiler that won’t blow your budget?

For the 4 million homes within the UK that are not connected to the Gas grid this can be a common concern. Especially if you have gone to switch on your heating ready for the cooler months and found your oil boiler wont fire up.

There are fewer oil boiler options to choose from compared to gas.  However this doesn’t mean you can’t benefit from an efficient, high performance boiler with a long warranty.

Efficient oil boilers are available as a combination (combi) boiler where the boiler can produce instant heat and hot water. Oil boilers also come as heat only boiler where hot water is generated by a hot water cylinder.

Total Energy are accredited installers for Worcester Bosch and Grant.  Both manufacturers have a range of highly efficient A-rated boilers.

In order to ensure that you have the correct boiler for your home it is really important you use an OFTEC registered heating engineer. OFTEC are the regulatory authority for the oil fired appliance industry.

Our top boiler manufacturers for efficient oil boilers are Grant UK and Worcester Bosch.

How to keep your oil boiler working efficiently?

To increase the longevity of your oil boiler it is important to invest in annual oil boiler servicing. If your oil boiler is under warranty, failing to keep up with servicing can render your boiler warranty void.  Even if your boiler is not under warranty a yearly service will help pick up any signs of wear and tear.  If ignored this could result in a costly breakdown. Your OFTEC engineer will give the boiler a good clean and ensure everything is working as it should. They will also carry out a range of safety checks.  A thorough oil boiler service will usually take around 2 hours to complete. The perfect time to ask questions about your heating system is during a service.
