With rising energy costs and environmental concerns, choosing an efficient boiler is more important than ever.

Choosing a new boiler is a significant investment, and understanding its efficiency rating is crucial for both your wallet and the planet. In the UK, boiler efficiency is labelled according to the Energy-related Products (ErP) Directive, making it easier to compare models and their impact on your energy bills and carbon footprint.

Decoding the Efficiency Labels

Under the ErP scheme, boilers are rated from A+++ (most efficient) to G (least efficient).

A+++ to A+: High efficiency condensing boilers, converting over 90% of fuel into heat, significantly reducing energy consumption and bills.
A to B: Still very efficient condensing boilers, achieving 86-90% efficiency.
C to D: Less efficient condensing boilers, falling in the 82-78% range.
E to F: Older non-condensing boilers, with lower efficiency (74-70%) and higher running costs.
G: Least efficient boilers, below 70% efficiency, and typically over 15 years old.

The impact on your energy bills

The higher the efficiency rating, the less energy your boiler wastes, translating to lower fuel bills. For example, switching from a G-rated to an A-rated boiler could save you hundreds of pounds annually. The Energy Saving Trust estimates that replacing an old G-rated boiler with an A-rated model could save an average household around £320 per year on energy bills.

Environmental benefits

Choosing a high-efficiency boiler also benefits the environment by reducing your carbon footprint. Less fuel used means fewer greenhouse gas emissions, contributing to a cleaner planet. The Energy Saving Trust estimates that the switch from a G-rated to an A-rated boiler could save around 700kg of CO2 emissions per year, equivalent to planting 35 trees!

Initial investment vs. long term savings

When choosing a new boiler, consider both the initial cost and the long-term savings on energy bills. While a higher-rated boiler might have a slightly higher upfront cost, the potential savings over its lifespan can be significant. Additionally, government grants and incentives are available in some cases to encourage the installation of more efficient boilers.
