Article 2U.K.Definitions
In addition to the definitions set out in Article 2 of Directive 2010/30/EC, the following definitions shall apply for the purposes of this Regulation:
‘heater’ means a space heater or combination heater;
‘space heater’ means a device that
provides heat to a water-based central heating system in order to reach and maintain at a desired level the indoor temperature of an enclosed space such as a building, a dwelling or a room; and
is equipped with one or more heat generators;
‘combination heater’ means a space heater that is designed to also provide heat to deliver hot drinking or sanitary water at given temperature levels, quantities and flow rates during given intervals, and is connected to an external supply of drinking or sanitary water;
‘water-based central heating system’ means a system using water as a heat transfer medium to distribute centrally generated heat to heat emitters for the space heating of buildings, or parts thereof;
‘heat generator’ means the part of a heater that generates the heat using one or more of the following processes:
combustion of fossil fuels and/or biomass fuels;
use of the Joule effect in electric resistance heating elements;
capture of ambient heat from an air source, water source or ground source, and/or waste heat;
‘rated heat output’ (Prated) means the declared heat output of a heater when providing space heating and, if applicable, water heating at standard rating conditions, expressed in kW; for heat pump space heaters and heat pump combination heaters the standard rating conditions for establishing the rated heat output are the reference design conditions, as set out in Annex VII, Table 10;
‘standard rating conditions’ means the operating conditions of heaters under average climate conditions for establishing the rated heat output, seasonal space heating energy efficiency, water heating energy efficiency and sound power level;
‘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;
‘biomass fuel’ means a gaseous or liquid fuel produced from biomass;
‘fossil fuel’ means a gaseous or liquid fuel of fossil origin;
‘cogeneration space heater’ means a space heater simultaneously generating heat and electricity in a single process;
‘temperature control’ means the equipment that interfaces with the end-user regarding the values and timing of the desired indoor temperature, and communicates relevant data to an interface of the heater such as a central processing unit, thus helping to regulate the indoor temperature(s);
‘solar device’ means a solar-only system, a solar collector, a solar hot water storage tank or a pump in the collector loop, which are placed on the market separately;
‘solar-only system’ means a device that is equipped with one or more solar collectors and solar hot water storage tanks and possibly pumps in the collector loop and other parts, which is placed on the market as one unit and is not equipped with any heat generator except possibly one or more back-up immersion heaters;
‘solar collector’ means a device designed to absorb global solar irradiance and to transfer the heat energy so produced to a fluid passing through it;
‘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;
‘solar hot water storage tank’ means a hot water storage tank storing heat energy produced by one or more solar collectors;
‘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;
‘package of space heater, temperature control and solar device’ means a package offered to the end-user containing one or more space heaters combined with one or more temperature controls and/or one or more solar devices;
‘package of combination heater, temperature control and solar device’ means a package offered to the end-user containing one or more combination heaters combined with one or more temperature controls, and/or one or more solar devices;
‘seasonal space heating energy efficiency’ (ηs ) means the ratio between the space heating demand for a designated heating season, supplied by a space heater, a combination heater, a package of space heater, temperature control and solar device or a package of combination heater, temperature control and solar device, and the annual energy consumption required to meet this demand, expressed in %;
‘water heating energy efficiency’ (ηwh ) means the ratio between the useful energy in the drinking or sanitary water provided by a combination heater or a package of combination heater, temperature control and solar device, and the energy required for its generation, expressed in %;
‘sound power level’ (LWA ) means the A-weighted sound power level, indoors and/or outdoors, expressed in dB.
For the purposes of Annexes II to VIII, additional definitions are set out in Annex I.
