The UK participation in its preparation was entrusted to Technical Committee RHE/24, Central heating installations. A list of organizations represented on this committee can be obtained on request to its secretary. BSI, as a member of CEN, is obliged to publish EN 15378 as a British Standard. However, attention is drawn to the fact that during the development of this European Standard, the UK committee expressed concern that it was overly complex to serve the purpose for which it was designed. Inspection class tables for use in the UK are given in the National Annex. This publication does not purport to include all the necessary provisions of a contract. Users are responsible for its correct application. Compliance with a British Standard cannot confer immunity from legal obligations.

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of an identical text or by endorsement, at the latest by March 2008, and conflicting national standards shall be withdrawn at the latest by March 2008. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association (Mandate M/343), and supports essential requirements of EU Directive 2002/91/EC on the energy performance of buildings (EPBD). It forms part of a series of standards aimed at European harmonisation of the methodology for calculation of the energy performance of buildings. An overview of the whole set of standards is given in prCEN/TR 15615. The subjects 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 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 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 requirements 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 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, the 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, Bulgaria, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and United Kingdom.

This European Standard includes, either in the normative text or in the informative annexes: inspection procedures; measurement procedures; calculation equations; sample reports; advice criteria. Procedures and methodologies defined in this European Standard are not intended to provide a full energy audit of the heating system. They are intended to: support identification of areas of possible improvements; define criteria to produce reliable advice on possible improvements of the energy performance of boilers and heating systems through replacement of components or other measures. Any replacement of appliances or modification of the heating system following advice should be designed according to appropriate methodologies. This may require additional input and investigation for detailed design and final check of economical effectiveness. Clauses 5 and 6 separately describe basic inspection procedures related to: regular inspection of boilers; one-off inspection of the entire heating system. This European Standard introduces inspection classes by which different levels of inspection accuracy and detailed inspection requirements can be determined, because: the same inspection procedure and level of details cannot reasonably be required for any kind and/or any size of boilers/heating systems; there are currently significant differences among member states with respect to: heating systems typologies; legal and/or standard requirements; maintenance and inspection practices. Alternative and/or optional partial inspection procedures and measurement methods for boilers and for other sub-systems of the heating system are described in the relevant annexes.
