Article 2 Definitions

In addition to the definitions set out in Article 2 of Directive 2009/125/EC, the following definitions shall apply for the purposes of this Regulation:

(1)

‘water heater’ means a device that

(a)

is connected to an external supply of drinking or sanitary water;

(b)

generates and transfers heat to deliver drinking or sanitary hot water at given temperature levels, quantities and flow rates during given intervals; and

(c)

is equipped with one or more heat generators;

(2)

‘heat generator’ means the part of a water heater that generates the heat using one or more of the following processes:

(a)

combustion of fossil fuels and/or biomass fuels;

(b)

use of the Joule effect in electric resistance heating elements;

(c)

capture of ambient heat from an air source, water source or ground source, and/or waste heat;

whereby a heat generator designed for a water heater and a water heater housing to be equipped with such a heat generator shall be also considered a water heater;

(3)

‘water heater housing’ means the part of a water heater designed to have a heat generator fitted;

(4)

‘rated heat output’ means the declared heat output of the water heater when providing water heating at standard rating conditions, expressed in kW;

(5)

‘storage volume’ (V) means the rated volume of a hot water storage tank or a storage water heater, expressed in litres;

(6)

‘standard rating conditions’ means the operating conditions of water heaters for establishing the rated heat output, water heating energy efficiency, sound power level and nitrogen oxide emissions, and of hot water storage tanks for establishing the standing loss;

(7)

‘biomass’ means the biodegradable fraction of products, waste and residues from biological origin from agriculture (including vegetal and animal substances), forestry and related industries including fisheries and aquaculture, as well as the biodegradable fraction of industrial and municipal waste;

(8)

‘biomass fuel’ means a gaseous or liquid fuel produced from biomass;

(9)

‘fossil fuel’ means a gaseous or liquid fuel of fossil origin;

(10)

‘conventional water heater’ means a water heater that generates heat using the combustion of fossil and/or biomass fuels and/or the Joule effect in electric resistance heating elements;

(11)

‘heat pump water heater’ means a water heater using ambient heat from an air source, water source or ground source, and/or waste heat for heat generation;

(12)

‘solar water heater’ means a water heater equipped with one or more solar collectors, solar hot water storage tanks, heat generators and possibly pumps in the collector loop and other parts; a solar water heater is placed on the market as one unit;

(13)

‘hot water storage tank’ means a vessel for storing hot water for water and/or space heating purposes, including any additives, which is not equipped with any heat generator except possibly one or more back-up immersion heaters;

(14)

‘back-up immersion heater’ means a Joule effect electric resistance heater that is part of a hot water storage tank and generates heat only when the external heat source is disrupted (including during maintenance periods) or out of order, or that is part of a solar hot water storage tank and provides heat when the solar heat source is not sufficient to satisfy required comfort levels;

(15)

‘water heating energy efficiency’ (η_wh ) means the ratio between the useful energy provided by a water heater and the energy required for its generation, expressed in %;

(16)

‘sound power level’ (L_WA ) means the A-weighted sound power level, indoors and/or outdoors, expressed in dB;

(17)

‘standing loss’ (S) means the heating power dissipated from a hot water storage tank at given water and ambient temperatures, expressed in W;

(18)

‘conversion coefficient’ (CC) means a coefficient reflecting the estimated 40 % average EU generation efficiency referred to in Directive 2012/27/EU of the European Parliament and of the Council(1); the value of the conversion coefficient is CC = 2,5.

For the purposes of Annexes II to VI, additional definitions are set out in Annex I.
