Commission Regulation (EU) No 813/2013
of 2 August 2013
implementing Directive 2009/125/EC of the European Parliament and of the Council with regard to ecodesign requirements for space heaters and combination heaters
(Text with EEA relevance)

THE EUROPEAN COMMISSION,
Having regard to the Treaty on the Functioning of the European Union,
Having regard to Directive 2009/125/EC of the European Parliament and of the Council of 21 October 2009 establishing a framework for the setting of ecodesign requirements for energy-related products and in particular Article 15(1) thereof,
OJ L 285, 31.10.2009, p. 10.
After consulting the Ecodesign Consultation Forum,
Whereas:
(1) Under Directive 2009/125/EC ecodesign requirements should be set by the Commission for energy-related products representing significant volumes of sales and trade, having a significant environmental impact and presenting significant potential for improvement through design in terms of their environmental impact without entailing excessive costs.
(2) Provisions on the efficiency of boilers were established by Council Directive 92/42/EEC of 21 May 1992 on efficiency requirements for new hot-water boilers fired with liquid or gaseous fuels.
OJ L 167, 22.6.1992, p. 17.
(3) Article 16(2)(a) of Directive 2009/125/EC provides, that in accordance with the procedure referred to in Article 19(3) and the criteria set out in Article 15(2), and after consulting the Ecodesign Consultation Forum, the Commission should, as appropriate, introduce implementing measures for products offering a high potential for cost-effective reduction of greenhouse gas emissions, such as for heating and water heating equipment.
(4) The Commission has carried out a preparatory study on the technical, environmental and economic aspects of space heaters and combination (space and water) heaters typically used in the Union. The study was devised together with stakeholders and interested parties from the Union and third countries, and the results have been made publicly available.
(5) The environmental aspects of space heaters and combination heaters that have been identified as significant for the purposes of this Regulation are energy consumption in the use phase and (for heat pump heaters) sound power levels. In addition, for heaters using fossil fuels, emissions of nitrogen oxides, carbon monoxide, particulate matter and hydrocarbons are identified as significant environmental aspects.
(6) It is not appropriate to set ecodesign requirements for emissions of carbon monoxide, particulate matter and hydrocarbons as no suitable European measurement methods are as yet available. With a view to developing such measurement methods, the Commission mandated the European standardisation organisations to consider ecodesign requirements for those emissions during the review of this Regulation. National provisions for ecodesign requirements on emissions of carbon monoxides, particulate matter and hydrocarbons of space heaters and combination heaters may be maintained or introduced until the corresponding Union ecodesign requirements enter into force. The provisions of Directive 2009/142/EC of the European Parliament and of the Council of 30 November 2009 relating to appliances burning gaseous fuels, which limit the combustion products of appliances burning gaseous fuels in relation to health and safety, are not affected.
OJ L 330, 16.12.2009, p. 10.
(7) The preparatory study shows that requirements regarding the other ecodesign parameters referred to in Annex I, Part 1 to Directive 2009/125/EC are not necessary in the case of space heaters and combination heaters. In particular, greenhouse gas emissions related to refrigerants used in heat pump heaters for heating today’s European building stock are not identified as significant. The appropriateness of setting ecodesign requirements for these greenhouse gas emissions will be reassessed when reviewing this Regulation.
(8) The scope of this Regulation should include boiler space heaters, cogeneration space heaters and heat pump space heaters providing heat to water-based central heating systems for space heating purposes, and boiler combination heaters and heat pump combination heaters providing heat to water-based central heating systems for space heating purposes and heat to deliver hot drinking and sanitary water. These heaters are designed to use gaseous or liquid fuels, including from biomass (unless predominantly), electricity and ambient or waste heat.
(9) Heaters that are designed for using gaseous or liquid fuels predominantly (more than 50 %) produced from biomass have specific technical characteristics which require further technical, economic and environmental analyses. Depending on the outcome of the analyses, ecodesign requirements for those heaters should be set at a later stage, if appropriate.
(10) Annual energy consumption related to space heaters and combination heaters was estimated to have been 12 089 PJ (about 289 Mtoe) in the Union in 2005, corresponding to 698 Mt CO2 emissions. Unless specific measures are taken, annual energy consumption is expected to be 10 688 PJ in 2020. Annual emissions of nitrogen oxides related to space heaters and combination heaters were estimated to have been 821 kt SOx equivalent in the Union in 2005. Unless specific measures are taken, annual emissions are expected to be 783 kt SOx equivalent in 2020. The preparatory study shows that the use-phase energy consumption and emissions of nitrogen oxides of space heaters and combination heaters can be significantly reduced.
(11) The energy consumption of space heaters and combination heaters can be reduced by applying existing cost-effective non-proprietary technologies which lead to a reduction in the combined costs of purchasing and operating these products.
(12) In the Union there are almost five million dwellings with shared open-flue systems. For technical reasons it is not possible to replace existing boiler space heaters and boiler combination heaters by efficient condensing boilers in dwellings with a shared open-flue system. The requirements contained in this Regulation allow non-condensing boilers specifically designed for such a configuration to remain on the market; this is to prevent undue costs for consumers, to give manufacturers time to develop boilers dedicated to more efficient heating technologies, and to give Member States time to reflect on national building codes.
(13) The combined effect of the ecodesign requirements set out in this Regulation and the Commission Delegated Regulation (EU) No 811/2013 of 18 February 2013 supplementing Directive 2010/30/EU of the European Parliament and of the Council with regard to energy labelling of space heaters, combination heaters, packages of space heater, temperature control and solar device and packages of combination heater, temperature control and solar device is expected to result by 2020 in estimated annual energy savings of about 1 900 PJ (about 45 Mtoe), corresponding to around 110 Mt CO2 emissions, and a reduction in annual nitrogen oxides emissions of some 270 kt SOx equivalent, compared to what would happen if no measures were taken.
See page 1 of this Official Journal.
(14) Ecodesign requirements should harmonise energy consumption, sound power level and nitrogen oxides emission requirements for space heaters and combination heaters throughout the Union, thus helping to make the internal market operate better and to improve the environmental performance of these products.
(15) The ecodesign requirements should not affect the functionality or affordability of space heaters or combination heaters from the end-user’s perspective and should not negatively affect health, safety or the environment.
(16) The ecodesign requirements should be introduced gradually to give manufacturers a sufficient timeframe to redesign their products subject to this Regulation. The timing should be such that cost impact for manufacturers, in particular for small and medium-sized enterprises, is taken into account, while ensuring timely achievement of the objectives of this Regulation.
(17) Product parameters should be measured and calculated using reliable, accurate and reproducible methods which take into account recognised state-of-the-art measurement and calculation methods, including, where available, harmonised standards adopted by the European standardisation organisations under a request from the Commission, in accordance with the procedures laid down in the Regulation (EU) No 1025/2012 of the European Parliament and of the Council of 25 October 2012 on European standardisation.
OJ L 316, 14.11.2012, p. 12.
(18) In accordance with Article 8(2) of Directive 2009/125/EC, this Regulation specifies which conformity assessment procedures apply.
(19) To facilitate compliance checks, manufacturers should provide information in the technical documentation referred to in Annexes IV and V to Directive 2009/125/EC insofar as that information relates to the requirements laid down in this Regulation.
(20) To further limit the environmental impact of space heaters and combination heaters, manufacturers should provide information on disassembly, recycling and/or disposal.
(21) In addition to the legally binding requirements laid down in this Regulation, indicative benchmarks for best available technologies should be identified to ensure that information on the life-cycle environmental performance of space heaters and combination heaters is widely available and easily accessible.
(22) Directive 92/42/EEC should be repealed, except for Articles 7(2) and 8 thereof and Annexes III to V thereto, and new provisions should be laid down by this Regulation to ensure that the scope is extended to heaters other than boilers, to further improve the energy efficiency of space heaters and combination heaters, and to improve other significant environmental aspects of space heaters and combination heaters.
(23) The measures provided for in this Regulation are in accordance with the opinion of the Committee established by Article 19(1) of Directive 2009/125/EC,

ANNEX I Definitions applicable for Annexes II to V
For the purposes of Annexes II to V the following definitions shall apply:

Definitions related to heaters
(1) ‘standby mode’ means a condition where the heater is connected to the mains power source, depends on energy input from the mains power source to work as intended and provides only the following functions, which may persist for an indefinite time: reactivation function, or reactivation function and only an indication of enabled reactivation function, and/or information or status display;

(c) The reference annual heat demand QH shall be the design load for heating Pdesignh multiplied by the annual equivalent active mode hours HHE of 2 066.
(d) The annual energy consumption QHE shall be calculated as the sum of:
the ratio of the reference annual heating demand QH and the active mode coefficient of performance SCOPon or active mode primary energy ratio SPERon and
the energy consumption for off, thermostat-off, standby, and crankcase heater mode during the heating season.
(e) The seasonal coefficient of performance SCOP or seasonal primary energy ratio SPER shall be calculated as the ratio of the reference annual heat demand QH and the annual energy consumption QHE .
(f) The seasonal space heating energy efficiency ηs shall be calculated as the seasonal coefficient of performance SCOP divided by the conversion coefficient CC or the seasonal primary energy ratio SPER, corrected by contributions accounting for temperature controls and, for water-/brine-to-water heat pump space heaters and heat pump combination heaters, the electricity consumption of one or more ground water pumps.
5. Water heating energy efficiency of combination heaters
The water heating energy efficiency ηwh of a combination heater shall be calculated as the ratio between the reference energy Qref of the declared load profile and the energy required for its generation under the following conditions:
(a) measurements shall be carried out using the load profiles set out in Table 7;
(b) measurements shall be carried out using a 24-hour measurement cycle as follows:
00:00 to 06:59: no water draw-off;
from 07:00: water draw-offs according to the declared load profile;
from end of last water draw-off until 24:00: no water draw-off;
(c) the declared load profile shall be the maximum load profile or the load profile one below the maximum load profile;
(d) for heat pump combination heaters, the following additional conditions apply:
heat pump combination heaters shall be tested under the conditions set out in Table 3;
heat pump combination heaters which use ventilation exhaust air as the heat source shall be tested under the conditions set out in Table 6.

ANNEX IV Product compliance verification by market surveillance authorities
The verification tolerances defined in this Annex relate only to the verification of the measured parameters by Great Britain authorities and shall not be used by the manufacturer or importer as an allowed tolerance to establish the values in the technical documentation or in interpreting these values with a view to achieving compliance or to communicate better performance by any means.
When verifying the compliance of a product model with the requirements laid down in this Regulation, for the requirements referred to in this Annex the authorities of Great Britain must apply the following procedure—
(1) The Great Britain authorities shall verify one single unit of the model.
(2) The model shall be considered to comply with the applicable requirements if:
(a) the values given in the technical documentation pursuant to paragraph 1(2) of Part 1 of Schedule 1A to the Ecodesign for Energy-Related Products Regulations 2010, and, where applicable, the values used to calculate these values, are not more favourable for the manufacturer or importer than the results of the corresponding measurements carried out pursuant to paragraph 1(2)(b)(vii) of Part 1 of Schedule 1A to those Regulations; and
Words in Annex 4 para. (2)(a) substituted (31.12.2020) by The Ecodesign for Energy-Related Products and Energy Information (Amendment) (EU Exit) Regulations 2019 (S.I. 2019/539), reg. 1(3), Sch. 2 para. 19(10)(c)(i); 2020 c. 1, Sch. 5 para. 1(1)

(b) the declared values meet any requirements laid down in this Regulation, and any required product information published by the manufacturer or importer does not contain values that are more favourable for the manufacturer or importer than the declared values; and
(c) when the Great Britain authorities test the unit of the model, the determined values (the values of the relevant parameters as measured in testing and the values calculated from these measurements) comply with the respective verification tolerances as given in Table 8.
(3) If the results referred to in point 2(a) or (b) are not achieved, the model and all other equivalent models shall be considered not to comply with this Regulation.
(4) If the result referred to in point 2(c) is not achieved, the Great Britain authorities shall select three additional units of the same model for testing. As an alternative, the three additional units selected may be of one or more different equivalent models.
(5) The model shall be considered to comply with the applicable requirements if, for these three units, the arithmetical mean of the determined values complies with the respective verification tolerances given in Table 8.
(6) If the result referred to in point 5 is not achieved, the model and all other equivalent models shall be considered not to comply with this Regulation.
(7) ...
Annex 4 para. (7) omitted (31.12.2020) by virtue of The Ecodesign for Energy-Related Products and Energy Information (Amendment) (EU Exit) Regulations 2019 (S.I. 2019/539), reg. 1(3), Sch. 2 para. 19(10)(d); 2020 c. 1, Sch. 5 para. 1(1)
The Great Britain authorities shall use the measurement and calculation methods set out in Annex III.
The Great Britain authorities shall only apply the verification tolerances that are set out in Table 8 and shall only use the procedure described in points 1 to 6 for the requirements referred to in this Annex. No other tolerances, such as those set out in designated standards or in any other measurement method, shall be applied.
