Definitions
Article 2
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) ‘solid fuel boiler’ means a device equipped with one or more solid fuel heat generators 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 ‘Pr’ 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 manufacturer'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 manufacturer's instructions and includes any fuel that is mentioned in the instruction manual for installers and end-users, on free access websites of manufacturers, 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) ‘seasonal space heating energy efficiency’ or ‘ η s ’ means the ratio between the space heating demand for a designated heating season supplied by a solid fuel boiler and the annual energy consumption required to meet that demand, expressed in %; (16) ‘particulate matter’ means particles of various shape, structure and density scattered in the gaseous phase of the flue gas. For the purposes of Annexes II to V, additional definitions are set out in Annex I.
