Water based surface embedded heating and cooling systems - Part 2: Floor heating: Prove methods for the determination of the thermal output using calculation and test methods
This European Standard specifies the boundary conditions and the prove methods for the determination of the thermal output of hot water floor heating systems as a function of the temperature difference between the heating medium and the room temperature.
This standard shall be applied to commercial trade and practical engineering if proved and certifiable values of the thermal output shall be used.
This European Standard applies to heating and cooling systems embedded into the enclosure surfaces of the room to be heated or to be cooled. This Part of this European Standard applies to hot water floor heating systems. Applying of Part 5 of this European Standard requires the prior use of this Part of this European Standard. Part 5 of this European Standard deals with the conversion of the thermal output of floor heating systems determined in Part 2 into the thermal output of heating surfaces embedded in walls and ceilings as well as into the thermal output of cooling surfaces embedded in floors, walls and ceilings.
The thermal output is proved by a calculation method (Clause 6) and by a test method (Clause 9). The calculation method is applicable to systems corresponding to the definitions in EN 1264 1 (type A, type B, type C, type D). For systems not corresponding to these definitions, the test method shall be used. The calculation method and the test method are consistent with each other and provide correlating and adequate prove results.
The prove results, expressed depending on further parameters, are the standard specific thermal output and the associated standard temperature difference between the heating medium and the room temperature as well as fields of characteristic curves showing the relationship between the specific thermal output and the temperature difference between the heating medium and the room.

Diese Europäische Norm legt die Randbedingungen und die Prüfverfahren für die Bestimmung der Wärme-leistung von Warmwasser Fußbodenheizsystemen in Abhängigkeit von der Differenz zwischen der Heiz-mittel und der Raumtemperatur fest.
Die vorliegende Norm ist auf den kommerziellen Handel und das praktische Ingenieurwesen anzuwenden, sofern geprüftenachgewiesene und zertifizierbare Werte für die Wärmeleistung erforderlich sind.
Diese Europäische Norm gilt für Heiz und Kühlsysteme, die in die Raumumschließungsflächen des zu heizenden oder zu kühlenden Raumes integriert sind. Der vorliegende Teil dieser Europäischen Norm gilt für Warmwasser-Fußbodenheizsysteme. Die Anwendung von Teil 5 dieser Europäischen Norm erfordert die vorherige Anwendung des vorliegenden Teils dieser Europäischen Norm. Teil 5 dieser Europäischen Norm behandelt die Umrechnung der in Teil 2 bestimmten Wärmeleistung der Fußbodenheizsysteme in die Wärme-leistung von Heizflächen in Wänden und Decken sowie in die Kühlleistung von Kühlflächen in Fußböden, Wänden und Decken.
Die Wärmeleistung wird durch ein Berechnungsverfahren (Abschnitt 6) und ein experimentelles Verfahren (Abschnitt 9) geprüft. Das Berechnungsverfahren ist auf Systeme anwendbar, die den Definitionen nach EN 1264 1 (Typ A, Typ B, Typ C, Typ D) entsprechen. Bei Systemen, die diesen Definitionen nicht entspre-chen, ist das experimentelle Verfahren anzuwenden. Das Berechnungsverfahren und das experimentelle Verfahren entsprechen einander und liefern korrelierende, adäquate Prüfergebnisse.
Als Prüfergebnisse werden die spezifische Normwärmeleistung mit der zugehörigen Normdifferenz zwischen der Heizmittel und der Raumtemperatur sowie Kennlinienfelder für die Beziehung zwischen der spezifischen Wärmeleistung und der Differenz zwischen der Heizmittel und der Raumtemperatur in Abhängigkeit von weiteren Parametern angegeben.

Introduction This European Standard is based on the realisation that in the field of commercial trade, the thermal output of heating and cooling systems represents the basis of rating. In order to be able to evaluate and compare different heating and/or cooling systems, it is, therefore, necessary to refer to values determined using one single, unambiguously defined method. The basis for doing so are the prove methods for the determination of the thermal output of floor heating systems specified in Part 2 of this European Standard. In analogy to the European Standard EN 442-2 (Radiators and convectors — Part 2: Test methods and rating), these prove methods provide characteristic partial load curves under defined boundary conditions as well as the characteristic output of the system represented by the standard thermal output together with the associated standard temperature difference between the heating medium and the room temperature. SIST EN 1264-2:2009
1 Scope This European Standard specifies the boundary conditions and the prove methods for the determination of the thermal output of hot water floor heating systems as a function of the temperature difference between the heating medium and the room temperature. This standard shall be applied to commercial trade and practical engineering if proved and certifiable values of the thermal output shall be used. This European Standard applies to heating and cooling systems embedded into the enclosure surfaces of the room to be heated or to be cooled. This Part of this European Standard applies to hot water floor heating systems. Applying of Part 5 of this European Standard requires the prior use of this Part of this European Standard. Part 5 of this European Standard deals with the conversion of the thermal output of floor heating systems determined in Part 2 into the thermal output of heating surfaces embedded in walls and ceilings as well as into the thermal output of cooling surfaces embedded in floors, walls and ceilings. The thermal output is proved by a calculation method (Clause 6) and by a test method (Clause 9). The calculation method is applicable to systems corresponding to the definitions in EN 1264-1 (type A, type B, type C, type D). For systems not corresponding to these definitions, the test method shall be used. The calculation method and the test method are consistent with each other and provide correlating and adequate prove results. The prove results, expressed depending on further parameters, are the standard specific thermal output and the associated standard temperature difference between the heating medium and the room temperature as well as fields of characteristic curves showing the relationship between the specific thermal output and the temperature difference between the heating medium and the room. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. EN 1264-1:1997, Floor heating — Systems and components — Part 1: Definitions and symbols prEN 1264-3:2007, Water based surface embedded heating and cooling systems — Part 3: Dimensioning 3 Definitions and symbols For the purposes of this document, the terms and definitions given in EN 1264-1:1997 apply. 4 Thermal boundary conditions A floor heating surface with a given average surface temperature exchanges the same thermal output in any room with the same indoor room temperature (standard indoor room temperature ϑi). It is, therefore, possible to give a basic characteristic curve of the relationship between specific thermal output and average surface temperature that is independent of the heating system and applicable to all floor heating surfaces (including those having peripheral areas with greater heat emissions) (see Figure A.1). In contrast, every floor heating system has its own maximum permissible specific thermal output, the limit specific thermal output, qG. This output is calculated for an ambient (standard) indoor room temperature SIST EN 1264-2:2009
