NOTE See Clause 3 for a definition of the terms used below.
This European standard applies to heat cost allocators which are used to capture the proportionate thermal output of radiators in consumer units.
If an account unit comprises consumer units of different types (e.g. technically different types of heating systems or differences due to the consumer behaviour, e.g. industrial plants as opposed to private apartments), it could be necessary to divide this account unit into groups of users.
Heat cost allocators enable the determination of the heat consumption only of each radiator in a consumer unit as a share of the total heat consumption of the account unit or user group (see Clause 4); it is therefore necessary to determine this total heat consumption either by measuring the consumed fuel quantity or the amount of heat delivered (the latter by means of a heat meter, for example).
For the appropriate use of the heat cost allocators in accordance with this standard, the heating system needs to:
- correspond to the state of the art at the time of installation of the heat cost allocators;
- be operated in accordance with the state of the art (see A.2).
This standard specifies that heat cost allocators shall not be used for heating systems where the temperature of the heating system falls below or exceeds the temperature limits of the heat cost allocators, where the rating factor for the thermal output, KQ, cannot be clearly specified or where the heating surface is inaccessible. This applies usually to the following heating systems:
- floor heating;
- radiant ceiling heating;
- flap controlled radiators;
- radiators with ventilators;
- fan assisted air heaters;
- heating systems with steam operated radiators.

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.

This document specifies, the requirements and test methods concerning the classification and marking of gas-fired central heating boilers that are fitted with atmospheric burners, fan assisted atmospheric burners and are hereafter referred to as “boilers”.
Where the word boiler is used, this is intended to be read as the boiler including its connecting ducts, ducts and terminals, if any.
This document covers gas-fired central heating boilers type B11, B11BS, B12, B12BS, B13, B13BS:
NOTE 1 For further background information on appliance types see EN 1749:2020.
a) that have a nominal heat input (on the basis of net calorific value) not exceeding 70 kW;
b) that use one or more combustible gases of the three gas families at the pressures stated in EN 437:2021;
c) where the temperature of the heat transfer fluid does not exceed 105 °C during normal operation;
d) where the maximum operating pressure in the water circuit does not exceed 6 bar;
e) which are declared in the technical instructions to be either a “low temperature boiler” or a “standard boiler”. If no declaration is given the boiler is to be considered a “standard boiler”;
f) which are intended to be installed inside a building or in a partially protected place;
g) which are intended to produce also hot water either by the instantaneous or storage principle, as a single unit;
h) which are designed for either sealed water systems or for open water systems.
NOTE 2 This document provides requirements for boilers with known constructions. For boilers with any alternative constructions, which might not fully be covered by this document, the risk associated with this alternative construction needs to be assessed.
An example of an assessment methodology, based upon risk assessment, is given in Clause 11.
This document does not cover all the requirements for:
aa) appliances that are intended to be connected to gas grids where the quality of the distributed gas is likely to vary to a large extent over the lifetime of the appliance (see Annex AB);
ab) appliances using flue dampers;
ac) appliances that have a nominal heat input (on the basis of net calorific value) exceeding 70 kW;

ak) appliances that are intended to burn natural gases of the second family where hydrogen is added to the natural gas;
al) boilers intended to be installed in areas accessible to elderly people and children;
am) boilers equipped with an adaptive combustion control function (ACCF).
NOTE Negative pressure relative to the pressure in the flue system can for example be caused by mechanical or thermal ventilation in airtight buildings.

This document specifies requirements and test methods for room temperature sensors used to control the room temperature.
This document is applicable to wall mounted and flush mounted room temperature sensors.
The following aspects are not covered by this document:
- pendulum temperature sensors;
- ceiling mounted temperature sensor;
- extract air temperature sensors.
NOTE The measured value available at the output of the sensor is influenced by the place where the sensor device is located and factors such as air velocity, wall temperature, self/waste heating of the device and the air temperature. The perceived temperature, which is important for the well-being of a person, depends among other factors on air temperature, temperature of the surrounding walls and air flow rate as indicated in EN ISO 7730.
The temperature sensor element can be combined with other sensors in one device. This document only deals with the room temperature sensing of this devices. Other sensors are not covered except of their influence on the room temperature sensing (e.g. self-heating).
This document specifies sensor characteristics contributing to the determination of the control accuracy of individual zone controller according to EN 15500 1.
