ANNEX VISupplementary provisions
ANNEX VI Indicative benchmarks referred to in Article 6 At the time of entry into force of this Regulation, the best available technology on the market for water heaters and hot water storage tanks in terms of water heating energy efficiency, sound power level, standing loss and emissions of nitrogen oxides was identified as follows: 1. BENCHMARKS FOR WATER HEATING ENERGY EFFICIENCY OF WATER HEATERS: Declared load profile 3XS XXS XS S M L XL XXL 3XL 4XL Water heating energy efficiency 35 % 35 % 38 % 38 % 75 % 110 % 115 % 120 % 130 % 130 % 2. BENCHMARKS FOR SOUND POWER LEVEL ( L WA ), OUTDOORS, OF HEAT PUMP WATER HEATERS WITH: (a) rated heat output ≤ 6 kW: 39 dB; (b) rated heat output > 6 kW and ≤ 12 kW: 40 dB; (c) rated heat output > 12 kW and ≤ 30 kW: 41 dB; (d) rated heat output > 30 kW and ≤ 70 kW: 67 dB. 3. BENCHMARK FOR STANDING LOSS OF HOT WATER STORAGE TANKS WITH STORAGE VOLUME V , EXPRESSED IN LITRES: 4. BENCHMARK FOR EMISSIONS OF NITROGEN OXIDES, EXPRESSED IN NITROGEN OXIDE, OF CONVENTIONAL WATER HEATERS USING GASEOUS FUELS: 35 mg/kWh fuel input in terms of GCV The benchmarks specified in points 1, 2 and 4 do not necessarily imply that a combination of these values is achievable for a single water heater.
