scope:

This standard deals with solar heating support systems for potable-water heating.

It can make sense, both technically and economically, to provide a second consumer, in addition to the "potable- water heating" consumer, with solar heat from one single solar loop. Examples are:

• space heating
• room-air cooling
• swimming-pool water heating in outdoor and indoor pools (see also VDI 2089)
• process heat

This standard focuses on solar heating systems for potable-water heating for multi-dwelling units with collector areas typically above 20 m2. Statements and results are often applicable to detached and semi-detached homes. Where special conditions exist for these small systems, they are pointed out.

In addition to the planning and design criteria, guidance is given on the system technology and the selection of components.

This standard mainly deals with solar heating systems for potable-water heating in residential buildings. Many details are also applicable to other fields of application. Part 2 of this series of standards pertains to applications in students' halls of residence, homes for the elderly, hospitals, indoor pools and at camping sites.
