TS 11260 EN 1264-1

TS 11260 EN 1264-1 is the Turkish adoption of the part of EN 1264 that defines the terminology and symbols used for hot water floor heating systems. Its role is to provide a common technical language so that design documents, calculations, and specifications describe the same components and symbols in a consistent way.

The stated scope covers hot water floor heating systems in residential buildings, offices, and other buildings whose use is comparable to residential premises. In general technical terms, these systems distribute heat from water circulating through circuits embedded in or beneath the floor structure, so clear naming of circuits, surfaces, components, and related geometric or thermal references is essential for correct communication.

How the terminology framework supports system design

A definitions-and-symbols standard does not by itself set performance limits or installation rules; instead, it aligns the language used across engineering documentation. That matters because floor heating uses terms that can differ from conventional radiator systems, especially when describing heat-emitting areas, pipe circuits, control-related references, and other elements that appear in drawings or calculation sheets.

For customers and engineers, the value of this document lies in reducing ambiguity. When everyone uses the same definitions and symbols, project information becomes easier to compare, interpret, and exchange between design, manufacturing, and installation contexts.

• Focuses on hot water floor heating systems in residential and similar buildings.
• Standardizes definitions and symbols rather than installation or performance requirements.
• Supports consistent use in drawings, calculations, and technical specifications.
• Helps align terminology for floor-based heat distribution systems.
