BS EN 1264-2-2021 Water based surface embedded heating and cooling systems Part 2: Floor heating: Methods for the determination of the thermal output using calculations and experimental tests. The EN 1264 series gives guidelines for surface embedded heating and cooling systems installed In buildings, residential and non-residential (eg. office, public, commercial and industrial buildings) and focuses on systems installed for the purpose of thermal comfort. The EN 1264 series gives guidelines for water based heating and cooling systems embedded into the enclosure surfaces of the room to be heated or to be cooled It also specifies the use of other heating media instead of water, as appropnate. The EN 1264 tones specifies standardized product characteristics by calculation and testing the thennal output of heating fur technical specifications and certification. For the design, construction and operation of these systems, see EN 1264-3 and EN 1264-4 for the types A, B, C. 0. H. I and j. For the types E, F and G. see the EN ISO 1 185S tones. The systems specified In the EN 1264 series are adpoined to the structural base of the enclosure surfaces of the buildir mounted directly or with fixing supports. The EN 1264 senes does not specify ceiling systems mounted In a suspended ceiling with a designed open air gap between the system and the l,uilding structure which allows the thermally induced circulation of the air. The thermal output at these systems can be determined according to the EN 14037 series and EN 14240. EN 1264-2 specIfies hot water floor heating systems. The application of EN 1264-S requires the prior use of EN 1264-2. EN 1264-5 specifIes the conversion of the thermal output of floor heating systems determined in EN 1264-2 into the thermal output of heating surfacet embedded in walls and ceilings as well as into the thermal output of cooling surfaces embedded in floors, walls and ceilings. EN 1264.2 specifies the boundary conditions and the test methods for the determination of the thermal output of hot water floor heating systems as a function of the temperature difference between the heating medium and the mom temperature. The thermal output is tested by a calculation method and by a measurement method, The cakulanon method is applicable to systems corresponding to the definitions in EN 1264-1 (type A. H, C, D, H, I and j). The measurement method gives guidance for systems not corresponding to...
