This European Standard applies to electric instantaneous water heaters for domestic hot water heating for household and similar applications, which show both of the following characteristics: - fulfilling at least one load pattern from Annex A - heating up to temperatures below the boiling temperature. This European Standard specifies terms, definitions and measurement methods for the assessment of energy efficiency. This European Standard does not take into account requirements regarding the safety of the appliances.

This European Standard applies to electrical instantaneous water heaters designed to operate as multifunctional appliances with electric rated power >2 kW.
This European Standard specifies tests for the assessment of the performance.

This European Standard applies to electrical instantaneous water heaters designed to operate as multifunctional appliances with electric rated power >2 kW. This European Standard specifies tests for the assessment of the performance.

This European Standard specifies methods for measuring the performance of electric storage water heaters for the production of sanitary hot water for household and similar use. The object is to state and define the principal performance characteristics of electric storage water heaters and to describe the test methods for measuring these characteristics. NOTE 1 This standard does not apply to; - storage water heaters that use electricity as a secondary source of heating the water; - storage water heaters that do not use a tank to storage hot water - electric storage water heaters that do not meet the minimum (or maximum) output performance of the smallest (or biggest) load profile, as defined in Table 4. NOTE 2 This standard does not specify performance or safety requirements. For safety requirements see EN 60335-1 in conjunction with EN 60335-2-21.

This document is applicable to gas-fired appliances producing domestic hot water. It applies to both instantaneous and storage appliances; water-heaters and combination boilers that have:
-   heat input not exceeding 70 kW; and
-   hot water storage capacity (if any) not exceeding 500 l.
In the case of combination boilers, with or without storage tank, domestic hot water production is integrated or coupled, the whole being marketed as a single unit.
The present document sets out in qualitative and quantitative terms the performance in delivery of domestic hot water for a selected variety of uses. It also gives a system for presenting the information to the user.

This European Standard sets out in qualitative and quantitative terms the performance in delivery of domestic hot water for a selected variety of uses. It also gives a system for presenting the information to the user.

This European Standard defines the specifications and test methods concerning the construction, safety, rational use of energy and fitness for purpose, and also the classification and marking of gas-fired instantaneous water heaters for sanitary uses, hereafter called “water heaters”.
This European Standard applies to water heaters:
-   of types AAS, B11, B11BS, B12, B12BS, B13, B13BS, B14, B22, B23, B32, B33, B44, B52, B53, C11, C12, C13, C21, C22, C23, C32, C33, C42, C43, C52, C53, C62, C63, C72, C73, C82and C83 according to CEN/TR 1749;
-   fitted with atmospheric burners;
-   equipped with atmospheric burners assisted by a fan for the supply of combustion air or evacuation of combustion products or fully premix burners;
-   using one or more combustible gases corresponding to the three gas families and at the pressures stated in accordance to EN 437;
-   of nominal heat input not exceeding 70 kW;
-   with an ignition burner or with direct ignition of the main burner.
In this European Standard, the heat inputs are expressed in relation to the net calorific value (Hi).
This European Standard does not contain all the requirements necessary for:
-   boiling water appliances;
-   appliances intended to be connected to a mechanical means of evacuating the combustion products;
-   appliances which fulfil a dual role of space heating and heating water for sanitary use;
-   appliances making use of the heat of condensation of the water contained in the combustion products;
-   water heaters of types B21, B31, B41, B42, B43 and B51.
This European Standard only covers water heaters where the fan, if any, is an integral part of the appliance.
This European Standard:
-   does not apply to appliances not intended to be connected to a flue when they are not fitted with an atmosphere sensing device;
-   takes account of the information given in Technical Report CEN/CR 1472:1994 with respect to marking.
Type B appliances should be with a combustion products discharge safety device to comply with essential requirement 3.4.3 of the Gas Appliances Directive 2009/142/EC. In this European Standard, the appliance is identified as type B11BS.
Appliances intended to be installed outdoors or in a room separate from inhabited rooms and provided with appropriate ventilation are not required to have this combustion products discharge safety device but, in this case, appropriate warnings on the packaging, and in the instructions should clearly define the limited authorized use for this type of appliance. In this European Standard, the appliance is identified as type B11.
The main symbols used in this European Standard are summarized in Annex F.

This European Standard defines the specifications and test methods for the construction, safety, rational use of energy and fitness for purpose, environment and classification and marking of gas-fired storage water heaters for domestic hot water uses, hereafter called "appliance".
This European Standard applies to appliances:
-   of types B11, B11BS, C11, C12, C13, C21, C31,, C32, C33, C42, C43, C51,C52, C53, C62, C63, C72, C73, C81 connected to an individual flue duct, C82 and C83 according to CEN/TR 1749;
-   fitted with atmospheric burners;
-   using one or more combustible gases corresponding to the three gas families and the pressures indicated in EN 437;
-   of nominal heat input not exceeding 150 kW (net calorific value);
-   fitted with electrically operated mechanical flue dampers that are positioned downstream of the heat exchanger.

This clause of Part 1 is applicable with the following exception: This European Standard applies to electrical instantaneous water heaters designed to operate as multifunctional appliances with electric rated power >2 kW. This European Standard specifies tests for the assessment of the performance.
