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. See also Clause 2 and Tables A.1 and B.1.
