Division 4 PACKAGES OF WATER HEATER AND SOLAR DEVICE

The fiche for packages of water heater and solar device shall contain the elements set out in Figure 1 for evaluating the water heating energy efficiency of a package of water heater and solar device, where the following information shall be included:

• I: the value of the water heating energy efficiency of the water heater, expressed in %,

• II: the value of the mathematical expression $\left(220\times Q_{\mathrm{ref}}\right)∕Q_{\mathrm{nonsol}}$ , where Q_ref is taken from Table 3 in Annex VII and Q_nonsol from the product fiche of the solar device for the declared load profile M, L, XL or XXL of the water heater,

• III: the value of the mathematical expression $\left(Q_{\mathrm{aux}}\times \mathrm{2,5}\right)∕\left(220\times Q_{\mathrm{ref}}\right)$ , expressed in %, where Q_aux is taken from the product fiche of the solar device and Q_ref from Table 3 in Annex VII for the declared load profile M, L, XL or XXL.
