Water based surface embedded heating and cooling systems - Part 4: Installation
The EN 1264 series gives guidelines for surface embedded heating and cooling systems installed in buildings, residential and non-residential (e.g. office, public, commercial and industrial buildings) and focuses on systems installed for the purpose of thermal comfort.
The EN 1264 series gives guidelines for water based heating and cooling systems embedded into the enclosure surfaces of the room to be heated or to be cooled. It also specifies the use of other heating media instead of water, as appropriate.
The EN 1264 series specifies standardized product characteristics by calculation and testing the thermal output of heating for technical specifications and certification. For the design, construction and operation of these systems, see EN 1264-3 and EN 1264-4 for the types A, B, C, D, H, I and J. For the types E, F and G, see the EN ISO 11855 series.
The systems specified in The EN 1264 series are adjoined to the structural base of the enclosure surfaces of the building, mounted directly or with fixing supports. The EN 1264 series does not specify ceiling systems mounted in a suspended ceiling with a designed open air gap between the system and the building structure which allows the thermally induced circulation of the air. The thermal output of these systems can be determined according to the EN 14037 series and EN 14240.
EN 1264-4 specifies uniform requirements for the design and the construction of heating and cooling floor, ceiling and wall structures to ensure that the heating/cooling systems are suited to the particular application.
The requirements specified by the EN 1264 series apply only to the components of the heating/cooling systems which are part of the heating/cooling system. EN 1264-4 does not cover other elements which are not part of the heating/cooling system.
Raumflächenintegrierte Heiz- und Kühlsysteme mit Wasserdurchströmung - Teil 4: Installation
Die Normenreihe EN 1264 gibt Leitlinien für in Wohn- und anderen Gebäuden (z. B. Bürogebäuden, öffentlichen Gebäuden sowie Gewerbe- und Industriegebäuden) installierte raumflächenintegrierte Heiz- und Kühlsysteme und legt einen Schwerpunkt auf Systeme, die für den Zweck der thermischen Behaglichkeit installiert werden.
Die Normenreihe EN 1264 gibt Leitlinien für Heiz- und Kühlsysteme mit Wasserdurchströmung, die in die Raumumschließungsflächen des zu heizenden oder des zu kühlenden Raumes eingebettet sind. Sie legt ggf. auch die entsprechende Verwendung anderer Heizmittel als Wasser fest.
Die Normenreihe EN 1264 legt die Identifizierung standardisierter Produktmerkmale durch Berechnung und Prüfung der Wärmeleistung der Heizung für technische Spezifikationen und die Zertifizierung fest. Für das Design, den Bau und den Betrieb dieser Anlagen siehe EN 1264 3 und EN 1264 4 für die Typen A, B, C, D, H, I und J. Für die Typen E, F und G siehe Normenreihe EN ISO 11855.
Die in der Normenreihe EN 1264 festgelegten Systeme grenzen an den tragenden Untergrund der Umschließungsflächen des Gebäudes an und werden direkt oder mit Befestigungshalterungen angebracht. Die Normenreihe EN 1264 trifft keine Festlegungen für in abgehängten Decken montierte Deckensysteme mit einem auslegungsgemäßen offenen Luftspalt zwischen dem System und der Gebäudestruktur, der eine thermisch induzierte Umwälzung der Luft erlaubt. Die Wärmeleistung dieser Systeme kann nach der Normenreihe EN 14037 und EN 14240 bestimmt werden.
EN 1264 4 legt einheitliche Anforderungen an die Planung und den Aufbau von zur Heizung oder Kühlung dienenden Fußboden , Decken- und Wandkonstruktionen fest, um sicherzustellen, dass die Heiz bzw. Kühlsysteme für den jeweiligen Verwendungszweck geeignet sind.
Die in der Normenreihe EN 1264 festgelegten Anforderungen gelten nur für die unmittelbar zum Heiz bzw. Kühlsystem gehörenden Bauteile. EN 1264 4 deckt keine anderen Bauteile ab, die nicht unmittelbar zum Heiz bzw. Kühlsystem gehören.
Systèmes de surfaces chauffantes et rafraîchissantes hydrauliques intégrées - Partie 4: Installation
La série EN 1264 fournit des lignes directrices pour les systèmes de surfaces chauffantes et rafraîchissantes intégrées dans les bâtiments résidentiels et non résidentiels (par exemple, des bureaux, des bâtiments publics, commerciaux et industriels), et se concentre sur les systèmes installés à des fins de confort thermique.
La série EN 1264 fournit des lignes directrices pour les systèmes de surfaces chauffantes et rafraîchissantes intégrées dans les parois des pièces à chauffer ou à rafraîchir. Elle spécifie également l'utilisation de fluides caloporteurs autres que l'eau, le cas échéant.
La série EN 1264 spécifie les caractéristiques normalisées des produits en calculant et en mettant à l'essai l'émission thermique du chauffage pour les spécifications techniques et la certification. Pour la conception, la construction et le fonctionnement de ces systèmes, voir l'EN 1264-3 et l'EN 1264-4 pour les types A, B, C, D, H, I et J. Pour les types E, F et G, voir la série EN ISO 11855.
Les systèmes spécifiés dans la série EN 1264 sont fixés directement ou à l'aide de supports de fixation au plancher porteur des parois du bâtiment. La série EN 1264 ne spécifie pas les systèmes de plafond montés dans un plafond suspendu, dont l'entrefer ouvert conçu entre le système et la structure du bâtiment permet la circulation de l'air induite par la chaleur. L'émission thermique de ces systèmes peut être déterminée selon la série EN 14037 et l'EN 14240.
L'EN 1264-4 spécifie des exigences uniformes pour la conception et la mise en oeuvre des systèmes de surfaces chauffantes et rafraîchissantes intégrées dans le sol, les plafonds et les murs afin qu'ils répondent à leur destination.
Les exigences spécifiées dans la série EN 1264 s'appliquent uniquement aux composants des systèmes de chauffage/de rafraîchissement faisant partie du système de chauffage / de rafraîchissement. L'EN 1264-4 ne couvre pas les autres composants ne faisant pas partie du système de chauffage / de rafraîchissement.

4 Requirements
4.1 Hydronic balancing
According to ISO 11855-6:2018, 4.8, water based heating and cooling systems shall have a hydronic
balancing. The components shall be adjusted in order to ensure the required flow rates. Under dynamic
conditions, e.g. during the heating up period, it shall be ensured that the hydraulic interaction between
the different heating circuits is small. The flow rates in the different circuits should not be greater than
the design flow rates.
Each circuit shall have a balancing device or balancing system.
The balance of the system shall be done according to the realized project, e.g. “as build”, because the
length of circuits realized can differ from the project, therefore once the system has been installed, the
flow rates shall be updated and then set on the manifold.
Depending on the situation of the heating and cooling system the distribution system shall be equipped
with facilities for degassing and sludge separation.
4.2 Floor heating and cooling systems
4.2.1 General structural preconditions
The installation of a water floor heating and/or cooling system shall follow the prior installation of any
electrical, sanitary and other pipe facilities. The structure as specified in 4.2.2.1 with the draught-free
closure of all building openings, e.g. windows and outer doors, shall be completed.
4.2.2 Building layers, building components
4.2.2.1 Supporting base
The supporting base shall be prepared in accordance with relevant standards.
Any pipe work or conduits shall be fixed and encased to provide a level base upon which thermal
insulation and/or acoustic insulation is added before laying the heating pipes. In this respect, the
necessary structural height shall be taken into acco
