Defines inspection procedures and optional measurement methods for the assessment of energy performance of existing boilers and heating systems.

This European Standard specifies inspection procedures and optional measurement methods for the assessment of energy performance of existing boilers and heating systems. Boiler types covered by this European Standard are: boilers for heating, domestic hot water or both; gas, liquid or solid fuel fired boilers. Parts of heating systems covered by this European Standard are: boilers, including generation control; other generation devices; domestic hot water production facilities; heating distribution network, including associated components and controls; heat emitters, including components and controls; space heating control system; storage and associated components; domestic hot water control system. This standard covers issues related to energy conservation and environmental performance.
