Division 4 CONDITIONS FOR TESTING SOLAR WATER HEATERS

The solar collector, solar hot water storage tank, pump in the collector loop (if applicable) and heat generator shall be tested separately. Where the solar collector and solar hot water storage tank cannot be tested separately, they shall be tested in combination. The heat generator shall be tested under the conditions set out in point 2 of this Annex.

The results shall be used for the calculations set out in point 3(b) of Annex IV under the conditions set out in Tables 2 and 3. For the purpose of establishing Q_tota the efficiency of the heat generator using the Joule effect in electric resistance heating elements is assumed to be 100/CC.
