TS EN 1264-1

TS EN 1264-1 defines the terms, system types and symbols used for water based surface embedded heating and cooling systems. It establishes the common technical language for systems integrated into building surfaces, helping designers, manufacturers and specifiers describe these systems consistently when they are used for thermal comfort.

Why terminology matters in this family of systems

In general technical terms, surface embedded systems transfer heat through building surfaces such as floors, walls or similar envelope elements by means of embedded pipework or comparable heat-transfer arrangements. Because performance, installation concept and system naming can vary across practice, a clear vocabulary is important. This part of EN 1264 focuses on definitions and symbols, so that the same technical concept is identified in a uniform way across documentation, calculation work and product descriptions.

Position within EN 1264

Within the EN 1264 series, this document provides the terminology foundation for water based radiant heating and cooling systems. The series as a whole is associated with surface embedded systems installed in residential and non-residential buildings, and it also allows for other heating media where appropriate. This part does not deal with design or operating details in depth; instead, it supports the consistent use of system names and symbols that other parts of the series rely on. The scope also makes clear that suspended-ceiling systems with an open air gap that depends on air circulation are outside this family.

• Provides common terminology for water based surface embedded heating and cooling systems.
• Defines system types and their characteristics at the vocabulary level.
• Supports consistent use of symbols across the EN 1264 series.
• Relates to systems mounted directly on, or with fixings to, building enclosure surfaces.
• Excludes suspended-ceiling systems with a designed open air gap and air circulation.
