TS 11260 EN 1264-1

TS 11260 EN 1264-1 is the first part of the floor-heating series and sets out the definitions and symbols used for hot water floor heating systems. It provides a common technical language for systems used in residential buildings, offices, and other buildings with a use pattern similar to housing.

Why definitions and symbols matter

Floor heating is a low-temperature heating approach in which heat is emitted over a large floor area. In that context, the naming of system components, circuit identification, and symbol use are important for design documents, drawings, and communication across the supply chain. As general technical context, this kind of vocabulary standard helps prevent ambiguity when the same term could otherwise be interpreted differently in different projects or organizations.

What this part covers in practice

• The standard is focused on hot water floor heating systems; it does not state coverage of electric floor heating systems in the supplied scope.
• Its application is limited to residential buildings, offices, and other buildings with a residential-like use pattern.
• As a terminology and symbols standard, it should be read as a reference for consistent language, not as a standalone source of design values or installation methods.
• The series context matters: this part supports later technical parts by fixing the basic terms and graphical conventions.

In broader engineering use, such standards help designers, manufacturers, and documentation teams align on one vocabulary for components, circuits, and schematic representation. TS 11260 EN 1264-1 serves that foundational role within the EN 1264 family.
