The radiant floor must be laid leaving a perimeter strip along all the walls that delimit the area to be heated.

BS EN – Water based surface embedded heating and cooling systems. Installation

Circuit closure and circuit calibration must be independent. There must be no areas of irregular shape. It is the part of the standard that regulates the installation of surface-embedded radiant systems. It details the minimum material requirements to be used with a radiant surface system and the 12644- that have to be met for successful installation.

This is to avoid excessive supply tubing making it difficult to manage the temperature of the different rooms. During transport and storage on site, tubing must be protected from external damage and direct sunlight. Tubing must be laid at least 50 mm from the perimeter and mm from any possible cause of damage fin the tubing e.

I want to be contacted. The flooring contractor must check that the chosen floor finish is compatible with the conditions. If superficial cuts are made to the screed, these must not have a depth greater than a third of the thickness of the screed.

This means that, dih the procedures and choices made before the radiant surface is laid, that established in UNI EN must be complied with, without exception, when installing the radiant system.

You may find similar items within these categories by selecting from the choices below:. It defines the conditions that must be present at the time of laying the radiant floor system: The distribution manifold must be positioned in such a way as to minimise the length of supply tubing required.

The two lengths of tubing of each circuit that cross the expansion joint both the feed and return tubes may cross only once must be protected with flexible insulation material for a length of at least 0. Guide to radiant comfort Efficient design Radiant cooling Regulation Norms.

The absence of leaks must be documented in a test report which must also include details of the pressure at which the test was performed. Prove methods for the determination of the thermal output using calculation and test methods. Tubing must be attached using a secure anchoring system that ensures the tubing does not move more than 5 mm vertically and more than 10 mm horizontally from the position where it was installed. These devices must also work in the absence of an electric current. Before laying the screed onto the coils, a pressure of no less than 4 bar and no greater than 6 bar must be applied to make sure there are no leaks.

The tubing used for the radiant floor circuits must have an oxygen barrier and meet the technical specifications of reference standards.

The perimeter strip and protective insulation layer must be positioned in such a way that the screed does not seep along the perimeter under the insulation. Determination of the thermal output BS EN Joints must be positioned by all the doors. For at least 3 days the screed must be protected from drying too quickly.

In relation to the screed, UNI EN recommends that its thickness is no less than that stipulated by the regulations specifying screed load capacity and bending strength class.
