2. DOMESTIC HOBS

2.2. Domestic gas hobs

The energy efficiency of gas burners in a domestic hob is calculated as follows:

Where:

— EE_{gas burner}

=

energy efficiency of a gas burner in % and rounded to the first decimal place,

— E_{gas burner}

=

energy content of the consumed gas for the prescribed heating in MJ and rounded to the first decimal place,

— E_theoretic

=

theoretic minimum required energy for the corresponding prescribed heating in MJ and rounded to the first decimal place.

The energy efficiency of the gas hob (EE_{gas hob} ) is calculated as the average of the energy efficiency of the different gas burners (EE_{gas burner} ) of the hob.
