EN 1264-4 : Water based surface embedded heating and cooling systems - Part 4: Installation.

This standard forms part of the EN 1264 series, which covers surface-embedded heating and cooling systems installed in the building fabric of residential and non-residential buildings for thermal comfort purposes, including systems using heat-transfer fluids other than water. The series defines standardised product characteristics through the calculation and testing of heating output. EN 1264-3 and EN 1264-4 cover the design, construction and operation of types A, B, C, D, H, I and J, while types E, F and G fall within the scope of the EN ISO 11855 series. The systems are attached to the structural floor, either directly or by means of supports. Suspended ceilings incorporating an air gap that allows heat-induced air circulation are excluded and are covered by EN 14037 and EN 14240. EN 1264-4 establishes uniform requirements for systems embedded in floors, ceilings and walls, limited to the components of the heating or cooling system.
