Heat cost allocators for the determination of the consumption of room heating radiators - Appliances without an electrical energy supply, based on the evaporation principle

Heat cost allocators in accordance with this standard are instruments for the registration of the heat output of radiators in consumer units. Consumer units are dwellings, office buildings, business premises, industrial plants in which the heat is supplied by a common central heating systems or by a common district heating connection. A complete grouping of consumer units is called an account unit.

Heizkostenverteiler für die Verbrauchswerterfassung von Raumheizflächen - Geräte ohne elektrische Energieversorgung nach dem Verdunstungsprinzip

Heizkostenverteiler nach dieser Norm sind Instrumente zur Erfassung der Wärmeabgabe von Heizkörpern in Nutzeinheiten. Unter Nutzeinheiten sind Wohnungs-, Büro-, Geschäfts-, Gewerbe- oder Industrieräumlichkeiten zu verstehen, deren Wärmeversorgung durch eine gemeinsame Zentralheizunsanlage oder über einen gemeinsamen Fernwärmeanschluß erfolgt. Die Gesamtheit der Nutzeinheiten bildet eine Abrechnungseinheit.

Répartiteurs de frais de chauffage pour enregistrer les valeurs de consommation de surfaces de corps de chauffe - Appareils sans alimentation en énergie électrique en vertu du principe d'évaporation

Les répartiteurs de frais de chauffage conformes à cette norme sont des instruments destinés à mesurer la chaleur émise par des radiateurs dans les unités d'utilisation. On entend par unités d'utilisation des locaux d'habitation, des locaux commerciaux, professionnels ou industriels et des bureaux, dont l'approvisionnement en chaleur se fait au moyen d'une installationde chauffage central ou par le truchement d'un raccordement commun à un système de chauffage urbain. L'ensemble des unités d'utilisation constitue une unité de calcul des frais.

Overview

EN 835:1994 (CEN) specifies requirements for heat cost allocators that determine the consumption of room heating radiators using the evaporation principle. These devices are appliances without an electrical energy supply and are intended to register the heat output of radiators in consumer units served by a common central or district heating system. A complete grouping of consumer units supplied together is termed an account unit. ICS classification: 91.140.10 (Central heating systems).

Key topics and requirements

EN 835:1994 focuses on the functional and application aspects of non-electrical heat cost allocators based on evaporation. Key technical topics and requirements covered by the standard include:

• Measurement principle: use of the evaporation principle to record relative radiator heat output without electrical power.
• Intended use: device application for consumer units such as dwellings, offices, business premises and industrial plants connected to central or district heating.
• Device characteristics: parameters that define how the appliance registers heat output and how readings are expressed for allocation.
• Installation and mounting: guidance on placement on radiators to ensure representative measurement of room heating.
• Performance and reliability: expected operational behavior under normal heating system conditions and typical building environments.
• Documentation and marking: identification, user information and records required for correct use and billing.
• Account unit concept: how readings from individual consumer units are aggregated for billing within a shared heating connection.

(EN 835:1994 is specifically limited to evaporation-type, non-powered heat cost allocators; it does not cover electrical or electronic heat meters.)

Applications

EN 835 is applicable in situations where radiator-level registration is required for fair distribution of heating costs across multiple consumers sharing a central or district heating system. Typical users and applications:

• Manufacturers designing or certifying evaporation-based heat cost allocators.
• Building owners and property managers implementing radiator-level cost allocation in multi-unit buildings.
• District and central heating operators who require consistent methods to allocate heat consumption.
• Energy auditors and consultants assessing heating cost allocation strategies and compliance.
• Installers and maintenance personnel responsible for correct placement and servicing.

Using EN 835 helps ensure consistent, comparable radiator consumption registration for billing and energy management without electrical power at the device.

Related standards

For comprehensive heat metering and cost allocation programs, EN 835 should be used alongside other CEN/ISO standards covering heat meters, building energy measurement, and billing methods (see national and CEN catalogs for specific references).
