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 EN 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.
