15、, the secretariat of which is held by DS. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by June 2006, and conflicting national standards shall be withdrawn at the latest by June 2006. The subjects
16、covered by CEN/TC 228 are the following: - design of heating systems (water based, electrical etc.); - installation of heating systems; - commissioning of heating systems; - instructions for operation, maintenance and use of heating systems; - methods for calculation of the design heat loss and heat
17、 loads; - methods for calculation of the energy performance of heating systems. Heating systems also include the effect of attached systems such as hot water production systems. All these standards are systems standards, i.e. they are based on requirements addressed to the system as a whole and not
18、dealing with requirements to the products within the system. Where possible, reference is made to other European or International Standards, a.o. product standards. However, use of products complying with relevant product standards is no guarantee of compliance with the system requirements. The requ
19、irements are mainly expressed as functional requirements, i.e. requirements dealing with the function of the system and not specifying shape, material, dimensions or the like. The guidelines describe ways to meet the requirements, but other ways to fulfil the functional requirements might be used if
20、 fulfilment can be proved. Heating systems differ among the member countries due to climate, traditions and national regulations. In some cases requirements are given as classes so national or individual needs may be accommodated. In cases where the standards contradict with national regulations, th
21、e latter should be followed. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Icelan

Scope This document specifies the design criteria for electrical heating systems in individual and collective resi
23、dential buildings, the commercial and industrial building sector. This doucment covers fixed electrical heaters which emit heat directly into space by use of electricity only. The following systems are included: electric instantaneous heating systems: natural or fan convector heaters; radiant panels
24、; radiators / resistance heaters; ceiling heating; infra-red and quartz linear heaters; thin slab floor heating; wall heating. electric non-instantaneous heating systems: full slab floor heating; room storage heaters; room storage fan heaters. This document does not cover radiant electric fires, mov
25、able heaters or electric heating systems that require a transfer medium outside of the appliance to deliver heat into the space. Examples of such systems include: air conditioning or cooling systems; unitary heat pumps; window, through the wall and split system; warm air distribution systems; centra
26、l storage serving hot water radiator or warm air systems; hot water production, either storage or direct; any individual appliance serving more than one room. Requirements for installation, commissioning, and operation maintenance and use of direct electrical heating systems are excluded from this d
27、ocument. This document does not overwrite national regulations. This document does not override or add to requirements in appliance standards. EN 14337:2005 (E) 5 2.
