7. Technical parameters of water heaters

The following parameters shall be established for water heaters:

(a)

the daily electricity consumption Q_elec in kWh, rounded to three decimal places;

(b)

the declared load profile, expressed by the appropriate letter in accordance with Table 3 of this Annex;

(c)

the sound power level in dB, indoors, rounded to the nearest integer (for heat pump water heaters, if applicable);

in addition, for water heaters using fossil and/or biomass fuels:

(d)

the daily fuel consumption Q_fuel in kWh in terms of GCV, rounded to three decimal places;

in addition, for water heaters for which the value of smart is declared as being ‘1’:

(e)

the weekly fuel consumption with smart controls Q_{fuel,week,smart} in kWh in terms of GCV, rounded to three decimal places;

(f)

the weekly electricity consumption with smart controls Q_{elec,week,smart} in kWh, rounded to three decimal places;

(g)

the weekly fuel consumption without smart controls Q_fuel,week in kWh in terms of GCV, rounded to three decimal places;

(h)

the weekly electricity consumption without smart controls Q_elec,week in kWh, rounded to three decimal places;

in addition, for solar water heaters:

(i)

the collector aperture area A_sol in m², rounded to two decimal places;

(j)

the zero-loss efficiency η₀ , rounded to three decimal places;

(k)

the first-order coefficient a₁ in W/(m² K), rounded to two decimal places;

(l)

(o)

the standby power consumption solstandby in W, rounded to two decimal places;

in addition, for heat pump water heaters:

(p)
