scope:

This document specifies inspection procedures for the assessment of energy performance of existing boilers and heating systems. Heat generators types covered by this standard are: - boilers for heating, domestic hot water or both; - gas, liquid, solid fuel fired combustion boilers; - electrically driven and gas driven heat pumps; - thermal solar systems for domestic hot water, heating or both; - other heat generators types, such as cogeneration units. Parts of heating systems covered by this standard are: - heat generators, including generation control; - heating distribution network, including associated components and controls; - heating emitters, including components and controls; - space heating control system; - heat storage and associated components; - domestic hot water production system. This standard covers issues related to energy conservation and environmental performance. Table 1 shows the relative position of this standard within the set of EPB standards in the context of the modular structure as set out in prEN ISO 52000 1. NOTE 1 - In prCEN ISO/TR 52000 2 the same table can be found, with, for each module, the numbers of the relevant EPB standards and accompanying technical reports that are published or in preparation. NOTE 2 - The modules represent EPB standards, although one EPB standard may cover more than one module and one module may be covered by more than one EPB standard, for instance a simplified and a detailed method respectively.
