Annex II Energy efficiency classes
United Kingdom
The energy efficiency class of a local space heater shall be determined on the basis of its energy efficiency index as set out in Table 1.
Table 1
Energy efficiency classes of local space heaters
| Energy efficiency class | Energy efficiency index (EEI) |
|---|---|
| A++ | EEI ≥ 130 |
| A+ | 107 ≤ EEI < 130 |
| A | 88 ≤ EEI < 107 |
| B | 82 ≤ EEI < 88 |
| C | 77 ≤ EEI < 82 |
| D | 72 ≤ EEI < 77 |
| E | 62 ≤ EEI < 72 |
| F | 42 ≤ EEI < 62 |
| G | EEI < 42 |
The energy efficiency index of a local space heater shall be calculated in accordance with Annex VIII.
