What Are Fuel Efficiency Ratings?

Fuel efficiency ratings for oil boilers are typically expressed as a percentage. This percentage represents the amount of energy from the fuel that the boiler converts into useful heat. The higher the efficiency rating, the more heat is produced from the same quantity of fuel, resulting in lower energy waste.

In the UK, boilers must meet certain energy efficiency standards to be legally sold and installed. The ErP (Energy-related Products) directive, introduced in 2015, categorises boilers based on their energy efficiency, among other factors. Understanding these categories and labels can help you make an informed choice when selecting an energy-efficient oil boiler.

The ErP label provides an energy efficiency rating ranging from A+++ (highest) to G (lowest). When searching for a new boiler, aim for a rating in the A category, as these models are the most energy-efficient. Investing in an A-rated boiler ensures that you are getting a unit that maximises the use of heating oil, which can result in substantial long-term savings.


Comparing Fuel Efficiency Ratings

To illustrate the impact of fuel efficiency ratings, let's compare two oil boilers: one with an A-rated label and another with a lower efficiency rating.

  • Boiler A (A-rated): This boiler has an energy efficiency rating of 90%. This means that it converts 90% of the heating oil it consumes into useful heat, while the remaining 10% is lost as waste.
  • Boiler B (Lower efficiency): In contrast, a lower-rated boiler might only have an efficiency rating of 70%, meaning that 30% of the heating oil is lost as waste.

Let's assume both boilers are used to heat a hot water cylinder in a home that consumes £1,000 worth of heating oil annually. Here's how their efficiency ratings affect the cost:

  • Boiler A (A-rated): With its 90% efficiency rating, it only wastes 10% of the heating oil, resulting in a heating cost of £900 per year.
  • Boiler B (Lower efficiency): In contrast, Boiler B wastes 30% of the heating oil, resulting in a heating cost of £1,300 per year.

The difference in heating costs between these two boilers is substantial. Boiler A, with its higher efficiency rating, leads to £400 in annual savings. Over a decade, this amounts to £4,000 in savings compared to Boiler B running costs. This illustrates how selecting a highly efficient oil boiler can pay off in the long run.
