Commission Delegated Regulation (EU) 2015/1187 Article 2

Definitions

Article 2

In addition to the definitions set out in Article 2 of Directive 2010/30/EU, the following definitions shall apply for the purposes of this Regulation: (1)  ‘solid fuel boiler’ means a device equipped with one or more solid fuel heat genererators that provides heat to a water-based central heating system in order to reach and maintain at a desired level the indoor temperature of one or more enclosed spaces, with a heat loss to its surrounding environment of not more than 6 % of rated heat output; (2)  ‘water-based central heating system’ means a system using water as a heat transfer medium to distribute centrally generated heat to heat emitting devices for the heating of enclosed spaces within buildings or parts thereof, including block heating or district heating networks; (3)  ‘solid fuel heat generator’ means the part of a solid fuel boiler that generates the heat through the combustion of solid fuels; (4)  ‘rated heat output’ or ‘ P r ’ means the declared heat output of a solid fuel boiler when providing heating of enclosed spaces with the preferred fuel, expressed in kW; (5)  ‘solid fuel’ means a fuel that is solid at normal indoor room temperatures, including solid biomass and solid fossil fuel; (6)  ‘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; (7)  ‘woody biomass’ means biomass originating from trees, bushes and shrubs, including log wood, chipped wood, compressed wood in the form of pellets, compressed wood in the form of briquettes, and sawdust; (8)  ‘non-woody biomass’ means biomass other than woody biomass, including straw, miscanthus, reeds, kernels, grains, olive stones, olive cakes and nut shells; (9)  ‘fossil fuel’ means fuel other than biomass, including anthracite, brown coal, coke, bituminous coal; for the purposes of this Regulation it also includes peat; (10)  ‘biomass boiler’ means a solid fuel boiler that uses biomass as the preferred fuel; (11)  ‘non-woody biomass boiler’ means a biomass boiler that uses non-woody biomass as the preferred fuel and for which woody biomass, fossil fuel or a blend of biomass and fossil fuel are not listed among its other suitable fuels; (12)  ‘preferred fuel’ means the single solid fuel which is to be preferably used for the boiler according to the supplier's instructions; (13)  ‘other suitable fuel’ means a solid fuel, other than the preferred fuel, which can be used in the solid fuel boiler according to the supplier's instructions and includes any fuel that is mentioned in the instruction manual for installers and end-users, on free access websites of suppliers, in technical promotional material and in advertisements; (14)  ‘solid fuel cogeneration boiler’ means a solid fuel boiler capable of simultaneously generating heat and electricity; (15)  ‘supplementary heater’ means a secondary boiler or heat pump falling within the scope of Delegated Regulation (EU) No 811/2013 or a secondary solid fuel boiler, which generates extra heat where the heat demand is greater than the rated heat output of the primary solid fuel boiler; (16)  ‘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 solid fuel boiler such as a central processing unit, thus helping to regulate the indoor temperature(s); (17)  ‘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; (18)  ‘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; (19)  ‘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; (20)  ‘solar hot water storage tank’ means a hot water storage tank storing heat energy produced by one or more solar collectors; (21)  ‘hot water storage tank’ means a vessel for storing hot water for water or space heating purposes, including any additives, which is not equipped with any heat generator except possibly one or more back-up immersion heaters; (22)  ‘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 supply 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; (23)  ‘package of a solid fuel boiler, supplementary heaters, temperature controls and solar devices’ means a package offered to the end-user containing a solid fuel boiler combined with one or more supplementary heaters, one or more temperature controls or one or more solar devices; (24)  ‘combination boiler’ means a solid fuel boiler 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. For the purposes of Annexes II to X, additional definitions are set out in Annex I.
