Division 1 DOMESTIC OVENS

United Kingdom

The energy consumption of a cavity of a domestic oven shall be measured for one standardised cycle, in a conventional mode and in a fan-forced mode, if available, by heating a standardised load soaked with water. It shall be verified that the temperature inside the oven cavity reaches the temperature setting of the thermostat and/or the oven control display within the duration of the test cycle. The energy consumption per cycle corresponding to the best performing mode (conventional mode or fan-forced mode) shall be used in the following calculations.

For each cavity of a domestic oven, the Energy Efficiency Index (EEI_cavity) shall be calculated according to the following formulas:

for domestic electric ovens:

{EEI}_{cavity} = \frac{{EC}_{electric cavity}}{{SEC}_{electric cavity}} \times 100

${SEC}_{electric cavity} = 0,0042 \times V + 0,55$ (in kWh)

for domestic gas ovens:

{EEI}_{cavity} = \frac{{EC}_{gas cavity}}{{SEC}_{gas cavity}} \times 100

${SEC}_{gas cavity} = 0,044 \times V + 3,53$ (in MJ)

Where:

— EEI_cavity

Energy Efficiency Index for each cavity of a domestic oven, rounded to the first decimal place,

— SEC_{electric cavity}

Standard Energy Consumption (electricity) required to heat a standardised load in a cavity of a domestic electric heated oven during a cycle, expressed in kWh, rounded to the second decimal place,

— SEC_{gas cavity}

Standard Energy Consumption required to heat a standardised load in a cavity of a domestic gas-fired oven during a cycle, expressed in MJ, rounded to the second decimal place,

— V

Volume of the cavity of the domestic oven in litres (L), rounded to the nearest integer,

— EC_{electric cavity}

Energy Consumption required to heat a standardised load in a cavity of a domestic electric heated oven during a cycle, expressed in kWh, rounded to the second decimal place,

— EC_{gas cavity}

Energy Consumption required to heat a standardised load in a gas-fired cavity of a domestic oven during a cycle, expressed in MJ, rounded to the second decimal place.
