implementing Directive 2009/125/EC of the European Parliament and of the Council 
with regard to ecodesign requirements fo r 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 Eu ropean Parliament and of the Council of 21 
October 2009 establishing a framework for th e setting of ecodesign requirements for energy-
related products
1 and in particular Article 15(1) thereof, 
After consulting the Ecodes ign Consultation Forum, 
Whereas: (1) Under Directive 2009/125/EC ecodesign requirements should be set by the 
Commission for energy-related products re presenting significant vo lumes 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 establ ished by Council Directive 
92/42/EC of 21 May 1992 on efficiency requi rements for new hot-water boilers fired 
with liquid or gaseous fuels
2. 
(3) Article 16(2)(a) of Directive 2009/125/EC pr ovides, 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 Foru m, the Commission should, as appropriate, 
introduce implementing measures for produc ts offering a high po tential 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

2 OJ L 167, 22.6.1992, p. 17.  
EN    EN 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 fo r the purposes of this Regula tion are energy consumption in 
the use phase and (for heat pump heaters) s ound power levels. In addition, for heaters 
using fossil fuels, emissions of nitrogen  oxides, carbon monoxide, particulate matter 
and hydrocarbons are identified as si gnificant environmental aspects. 
(6) It is not appropriate to set ecodesign requirements fo r emissions of carbon monoxide, 
particulate matter and hydrocarbons as no su itable European measurement methods 
are as yet available. With a view to developing such measurement methods, the 
Commission mandated the European standard isation bodies to consider ecodesign 
requirements for those emissions during th e review of this Regulation. National 
provisions for ecodesign requirements on em issions of carbon monoxides, particulate 
matter and hydrocarbons of space heaters and combination heaters may be maintained until the corresponding Union ecodesign requirements enter in to 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
3, which limit the 
combustion products of appliances burning ga seous fuels in relation to health and 
safety, are not affected. 
(7) The preparatory study shows that requir ements 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 combina tion 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 gr eenhouse gas emissions will be reassessed 
when reviewing this Regulation. 
(8) The scope of this Regulation should includ e 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 wa ter-based central heating systems for space 
heating purposes and heat to deliver hot drin king and sanitary water. These heaters are 
designed to use gaseous or liquid fuel s, including from biomass (unless 
predominantly), electricity and ambient or waste heat. 
(9) Depending on the outcome of further technica l, economic and environmental analyses, 
ecodesign requirements for space heaters and combination heaters designed for solid 
fuels or predominantly designed for gaseous or liquid biomass fuels should be set at a 
later stage, if appropriate. 
(10) Annual energy consumption related to spa ce heaters and combination heaters was 
estimated to have been 12
 089 PJ (about 289 Mtoe) in the Union in 2005, 
corresponding to 698 Mt CO 2 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 combinati on heaters were estimated to have been 
                                                 
3 OJ L 330, 16.12.2009, p. 10.  
EN    EN 821 kt SO x equivalent in the Un ion in 2005. Unless specifi c measures are taken, 
annual emissions are expected to be 783 kt SO x equivalent in 2020. The preparatory 
study shows that the use-phase energy consum ption and emissions of nitrogen oxides 
of space heaters and combination he aters can be significantly reduced. 
(11) The energy consumption of space heaters and combinati on heaters can be reduced by 
applying existing cost-effective non-proprietary  technologies which lead to a reduction 
in the combined costs of purchas ing 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 condens ing boilers in dwellings with a shared 
open-flue system. The requirements cont ained in this Regulation allow non-
condensing boilers specifical ly 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 requi rements set out in th is Regulation and the 
Commission Delegated Regul ation (EU) No … of … supplementing Directive 
2010/30/EU of the European Parliament and of the Council with regard to energy 
labelling of space heaters, combination heat ers, packages of space heater, temperature 
control and solar device and packages of combination heater, temperature control, solar device and passive flue heat recove ry device [Number of the Regulation and OJ 
reference in footnote to be inserted before publication in the OJ] is expected to result 
in estimated annual energy savings of about 1
 900 PJ (about 45 Mt oe), corresponding 
to around 110 Mt CO 2 emissions, and a reduction in annual nitrogen oxides emissions 
of some 270 kt SO x equivalent by 2020, compared to what would happen if no 
measures were taken. 
(14) Ecodesign requirements shoul d harmonise energy consum ption, sound power level 
and nitrogen oxides emission requirements fo r 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, sa fety or the environment. 
(16) The ecodesign requirements should be introduc ed gradually to give manufacturers a 
sufficient timeframe to redesi gn their products s ubject to this Regulation. The timing 
should be such that cost impact for manufact urers, 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 avai lable, harmonised standards adopted by 
the European standardisation bodies under a request from the Commission, in accordance with the procedures laid down in the Directive 98/34/EC of the European Parliament and of the Council of 22 June  1998 laying down a procedure for the  
EN    EN provision of information in th e field of technical standards and regulations and of rules 
on Information Society services4. 
(18) In accordance with Article 8(2) of Direct ive 2009/125/EC, this Regulation specifies 
which conformity assessment procedures apply. 
(19) To facilitate compliance checks, manufactur ers should provide information in the 
technical documentation referred to in A nnexes 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 bindi ng requirements laid down in  this Regulation, indicative 
benchmarks for best available technologies  should be identified to ensure that 
information on the life-cycle environmen tal performance of space heaters and 
combination heaters is widely available and easily accessible. 
(22) Directive 92/42/EC should be repealed 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 sp ace heaters and combina tion heaters, and to 
improve other significant environmental as pects of space heaters and combination 
heaters. 
(23) The measures provided for in this Regulati on are in accordance with the opinion of the 
Committee established by Article 19(1) of Directive 2009/125/EC,
