Heat meters - Part 6: Installation, commissioning, operational monitoring and maintenance

This European Standard specifies commissioning, operational monitoring and maintenance and applies to heat meters. Heat meters are instruments intended for measuring the energy which in a heat-exchange circuit is absorbed (cooling) or given up (heating) by a liquid called the heat-conveying liquid. The heat meter indicates the quantity of heat in legal units.
Electrical safety requirements are not covered by this European Standard.
Pressure safety requirements are not covered by this European Standard.
Surface mounted temperature sensors are not covered by this European Standard.
This standard covers meters for closed systems only, where the differential pressure over the thermal load is limited.

Diese Europäische Norm legt die Inbetriebnahme, die Überwachung und die Wartung von Wärmezählern fest. Wärmezähler sind Geräte, die dazu dienen, die Energiemenge zu messen, die in einem Wärmetauscherkreislauf durch eine als Wärmeträgerflüssigkeit bezeichnete Flüssigkeit aufgenommen (Kühlen) oder abgegeben (Heizen) wird. Der Wärmezähler zeigt die Wärmemenge in gesetzlichen Einheiten an.
Elektrische Sicherheitsanforderungen werden in dieser Europäischen Norm nicht behandelt.
Den Druck betreffende Sicherheitsanforderungen werden in dieser Europäischen Norm nicht behandelt.
Oberflächenmontierte Temperaturfühler werden in dieser Europäischen Norm nicht behandelt.
Die vorliegende Norm behandelt ausschließlich Zähler für geschlossene Systeme, in denen der Differenz-druck am Wärmeüberträger begrenzt ist.

Compteurs d'énergie thermique - Partie 6 : Installation, mise en service, surveillance et maintenance

La présente Norme européenne spécifie l'installation, la mise en service, à la surveillance de fonctionnement et la maintenance et s'applique aux compteurs d'énergie thermique. Les compteurs d'énergie thermique sont des instruments destinés à mesurer l'énergie thermique qui, dans un circuit d'échange thermique, est absorbée (refroidissement) ou cédée (chauffage) par un liquide appelé « liquide caloporteur ». Le compteur d'énergie thermique fournit la quantité d'énergie thermique en unités de mesure légales.
La présente Norme européenne ne traite pas des prescriptions de sécurité électrique.
La présente Norme européenne ne traite pas des prescriptions de sécurité relative à la pression.
La présente Norme européenne ne traite pas des sondes de température montées en surface.
La présente norme couvre les compteurs pour les systèmes fermés uniquement, où la pression différentielle dans la charge thermique est limitée.

Overview

SIST EN 1434-6:2016/oprA1:2017 is a European Standard developed by CEN that specifically governs the installation, commissioning, operational monitoring, and maintenance of thermal energy meters. These meters are essential instruments designed to measure the quantity of thermal energy transferred in closed heating and cooling systems, using a heat-conveying liquid. This amendment to the original EN 1434-6:2015 strengthens and updates procedures and terminologies, ensuring compliance with Directive 2014/32/EU and harmonizing measurement standards across Europe.

This standard focuses on thermal energy meters used in circuits where differential pressure over the thermal load is limited. It excludes electrical and pressure safety requirements as well as surface-mounted temperature sensors, targeting only meters in closed systems ensuring high accuracy and reliability in energy measurement.

Key Topics

• Thermal energy meter definitions and terms: Clarifies critical terminology such as thermal energy system, primary circuit, thermal energy mains, and inlet/outlet limbs.
• Installation requirements: Guidelines for proper placement and connection of thermal energy meters in heating and cooling systems to ensure precise energy measurement.
• Commissioning procedures: Step-by-step instructions for initial setup, calibration, and verification of meter functionality before operational use.
• Operational monitoring: Ongoing inspection and testing protocols to detect performance deviations and maintain meter accuracy during service life.
• Maintenance recommendations: Routine maintenance activities to ensure meters perform reliably, including checks on fittings and accessories.
• Compliance with EU Directive 2014/32/EU: Establishes conformity criteria for manufacturers and users within EU and EFTA member states, with presumption of conformity when compliance is met.

Applications

SIST EN 1434-6:2016/oprA1:2017 is widely applicable in various sectors requiring accurate thermal energy measurement, including:

• Residential, commercial, and industrial heating and cooling systems
• District heating and cooling network operators who rely on precise meter data for energy billing and monitoring
• Energy management professionals implementing energy efficiency strategies
• Meter manufacturers designing compliant, modular thermal energy metering solutions for EU markets
• Facility managers responsible for equipment commissioning and maintenance in HVAC systems

By adhering to this standard, stakeholders ensure that thermal energy meters operate accurately, reducing billing disputes, optimizing energy consumption, and supporting regulatory compliance requirements.

Related Standards

SIST EN 1434-6:2016/oprA1:2017 forms part of the EN 1434 series, which is a comprehensive framework covering thermal energy meters:

• EN 1434-1: General requirements
• EN 1434-2: Meters suitable for liquids other than water
• EN 1434-3: Measurement accuracy
• EN 1434-4: Meter performance testing methods
• EN 1434-5: Installation requirements for meters measuring for cooling energy
• EN 1434-6: Installation, commissioning, operational monitoring, and maintenance (this standard)
• Additional parts that cover related components and system integration

Compliance with this suite of standards ensures full coverage of meter design, testing, installation, and maintenance with uniform European harmonization.
