Heating systems in buildings - Method for calculation of system energy requirements and system efficiencies - Part 3-3: Domestic hot water systems, generation

Publication date:   Apr 30, 2008

Scope

This European Standard is part of a set of standards covering the methods for calculation of system energy requirements and system efficiencies of heating systems in buildings. In particular this standard is one of a number of standards dealing with domestic hot water systems.
The scope of this specific part is to standardise the methods for calculation of:
- thermal losses from the domestic hot water generation system;
- recoverable thermal losses for space heating from the domestic hot water generation system;
- auxiliary energy of the domestic hot water generation systems.
These values are input data for calculation of the overall energy use according to prEN 15603 and
EN 15316-1.
This European Standard specifies the:
- inputs;
- calculation methods;
outputs.
