Energy Efficiency Rating Scale:
| From: | To: |
The Energy Efficiency Rating (EER) is a standardized scale from A to G that indicates how energy efficient an appliance is. A-rated appliances are the most efficient, while G-rated are the least efficient, helping consumers make informed choices about energy consumption.
The calculator determines the energy efficiency rating based on annual energy consumption:
Where lower energy consumption results in higher efficiency ratings (A being most efficient)
Details: Understanding energy efficiency ratings helps consumers save money on energy bills, reduce environmental impact, and make informed purchasing decisions for household appliances.
Tips: Enter the annual energy consumption in kWh/year and select the appliance type. The calculator will determine the appropriate energy efficiency rating from A (most efficient) to G (least efficient).
Q1: What does the EER scale represent?
A: The EER scale from A to G represents the energy efficiency of appliances, with A being the most energy efficient and G being the least efficient.
Q2: How is energy consumption measured?
A: Energy consumption is typically measured in kilowatt-hours (kWh) per year, representing the amount of energy an appliance uses annually under normal operating conditions.
Q3: Are EER ratings mandatory in the UK?
A: Yes, energy efficiency ratings are mandatory for most household appliances sold in the UK under the Energy Labelling Regulation.
Q4: Can EER ratings change over time?
A: Yes, rating scales are periodically updated to reflect technological improvements and encourage manufacturers to develop more efficient products.
Q5: How much can I save with higher EER ratings?
A: Choosing A-rated appliances over lower-rated ones can save significant amounts on energy bills over the appliance's lifetime, potentially hundreds of pounds.
