(Text with EEA relevance)
THE EUROPEAN COMMI SSION,
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 products1,and in particular Article 15(1) thereof,
After consulting the Consultation Forum referred to in Article 18 of Directive 2009/125/EC ,
Whereas:
(1) Directive 2009/125/EC requires the Commission to set ecodesign requirements for 
energy -related products that represe nt significant volumes of sales and trade, that have 
a significant environmental impact and that present significant potential for 
improvement in terms of their environmental impact without entailing excessive costs.
(2) Article 16(2) 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 Consultation Forum, the Commission should, if appropriate, introduce 
implementing measures for products offering a high potential for cost -effective 
reduction of greenhouse gas emissions, such as heating equipment, including solid fuel 
boilers and packages of a solid fuel boiler , supplementary heater s, temperature 
control sand solar device s.
(3) The Commission has carri ed out a preparatory stud y to anal ysethe technical, 
environmental and economic aspects of the solid fuel boiler stypically used in 
households and for commercial purposes . The study  has been carried out with 
stakeholders and interested parties from the Uni on and third countries, and the results 
have been made publicl y available.
(4) The environmental aspects of solid fuel boilers that have been identified as significant 
for the purposes of this Regulation are energy consumption in the use phase and 
  
1OJ L 285, 31.10.2009, p. 10.EN 3 ENemissions of particulate matter (dust) , organic gaseous compounds, carbon monoxide 
and nitrogen oxides in the use phase .The annual energy consumption related to solid 
fuel boilers is expected to be 530petajoules ( ‘PJ’)(approximately 12.7 million tonnes 
of oil equiv alent ‘Mtoe ’) in 20 30and annual emissions are expected to be 25
kilotonnes (‘kt’)of particulate matter , 25kt of organic gaseous compounds and 292kt 
of carbon monoxide in 20 30.Emissions of nitrogen oxides are expected to increase 
because of potential new solid fuel boiler designs aiming at higher energy efficiency
and lower organic emissions . The preparatory study shows that use -phase energy 
consumption and emissions bysolid fuel boilers can be significantl y reduced.
(5) The preparatory study shows that further requirements regarding ecodesign parameters 
for products referred to in Part 1 of Annex I to Directive 2009/125/EC are not 
necessary in the case of solid fuel boilers .In particular, emissions of dioxins and 
furans are not ide ntified as significant.
(6) Boilers generating heat exclusively forproviding hot drinking or sanitary water , 
boilers for heating and distributing gaseous heat transfer media , cogeneration boilers 
with anelectrical capacity of 50 kW or more and have specific technical 
characteristic s and should therefore be exempted from this Regulation. Non-wood y 
biomass boilers areexempted ,because at present there is insufficient European -wide 
information to determine appropriate levels for the ecodesign requirements for them
and they mayhave fu rther significant environmental impacts ,such as furan and dioxin
emissions .The appropriateness of setting ecodesign requirements for non-wood y 
boilers will be reassessed when reviewing this Regulation.
(7) The energy consumption and emissions ofsolid fuel b oilers could be reduced by 
apply ing existing non -proprietary technologies without an increase in the combined 
costs of purchasing and operating these products.
(8) The combined effect of the ecodesign requirements set out in this Regulation and 
Commission Delegated Regulation (EU) No … of … supplementing Directive 
2010/30/EU of the European Parliament and of the Council with regard to energy 
labelling of solid fuel boilers and packages of a solid fuel boiler , supplementary
heater s, temperature control sand solar device s2is expected to result by2030 in 
estimated annual energy savings of approximately 22PJ (approximately 0.5Mtoe), 
together with related carbon dioxide (‘CO 2’)emission reductions of approximately
200 k t,and a reduction of 14 ktin particulate m atter, 14 ktin organic gaseous 
compounds, and 147ktin carbon monoxide .
(9) Ecodesign requirements should harmonise energy  consumption and emission 
requirements for solid fuel boilers throughout the Union, forthe internal market to 
operate better and in ord er to improve the environmental performance of those 
products.
(10) The ecodesign requirements should not affect the functionality or affordability ofsolid 
fuel boilers from theend-user’s perspective and should not negativel y affect health, 
safet y or the envi ronment.
  
2OJ [...] [... ], [...], [...].EN 4 EN(11) The introduction of ecodesign requirements should give manufacturers sufficient time 
to redesign their products subject to this Regulation . The timing should take into 
account the impact on manufacturers ’ costs , in particular for small and medium -sized 
enterprises, is taken into account, while ensuring timely achievement of the objectives 
of this Regulation.
(12) Product parameters should be measured and calculated using reliable, accurate and 
reproducible methods which take into account recognised stat e-of-the-art measurement 
and calculation methods ,including, where available, harmonised standards adopted b y 
the European standardisation organisations following a request by the Commission, in 
accordance with the procedures laid down in Regulation (EU) 1 025/2012 of the 
European Parliament and of the Council of 25 October 2012 on European 
standardisation3.
(13) In accordance with Article 8 of Directive 2009/125/EC, this Regulation specifies 
which conformit y assessment procedures apply.
(14) In order t o facilitate co mpliance checks, manufacturers should provide the information 
contained in the technical documentation referred to in Annexes I V and V toDirective 
2009/125/EC insofar as th atinformation relates to the requirements laid down in this 
Regulation.
(15) To further limit the environmental impact of solid fuel boilers , manufacturers should 
provide information on disassembly , recy cling and disposal.
(16) In addition to the legally binding requirements laid down in this Regulation, indicative 
benchmarks for best available t echnologies should be determined to ensure that
information on the life -cycle environmental performance of solid fuel boilers is widel y 
available and easil y accessible .
(17) The measures provided for in this Regulation are in accordance with the opinion of the 
Committee established under Article 19(1) of Directive 2009/125/EC ,

F(2) = 2.5 •(elmax + 1.3 • PSB) / Pn
5. Calculation of gross calorific value
The gross calorific value ( GCV ) shall be obtained from the gross calorific value 
moisture free ( GCV mf) by the apply ing the following conversion :
GCV = GCV mf × (1 -M)
where :
(a) GCV and GCV mf are expressed in megajoules per kilogram;EN 17 EN(b) Mis the moisture content of the fuel ,as used in solid fuel boilers ,as a 
proportion of the total mass of the fuel.
6. Seasonal space heating emissions
(a) Emissions of particulate matter, organic gaseous compounds, carbon monoxide 
and nitrogen oxides shall be expressed standardis ed to a dry flue gas basis at 
10% ox ygen and sta ndard condition sat 0°C and 1013 millibar.
(b) The seasonal space heating energy emissions Esof respectivel y particulate 
matter, organic gaseous compounds, carbon monoxide and nitrogen oxides are 
calculated as follows:
(1) for manuall y stoked solid fuel boilers thatcan be operated at 50 % of the 
rated heat output in continuous mode, and for automatically stoked solid 
fuel boilers :
Es= 0.85 • Es,p+ 0.15 • Es,n
(2) for manuall y stoked solid fuel boilers thatcannot be operated at 50 % or 
less of the rated heat outpu t in continuous mode , and for solid fuel 
cogeneration boilers :
Es= E s,n
where:
(a)Es,pare the emissions of respectivel y particulate matter, organic 
gaseous compounds, carbon monoxide and nitrogen oxides 
measured at 30 % or 50 % of rated heat output, as applicable ;
(b)Es,nare the emissions of respectivel y particulate matter, organic 
gaseous compounds, carbon monoxide and nitrogen oxides 
measured at rated heat output .
(c) Emissions of particulate matter shall be measured bya gravimetric method 
excluding an y particu late matter formed by organic gaseous compounds when 
fluegas is mixed with ambient air.
(d) Emissions of nitrogen oxides shall be measured as the sum of nitrogen 
monoxide and nitrogen dioxide, and expressed in nitrogen dioxide .EN 18 ENANNEX IV
Verification procedur e for market surveillance purposes
When performing the market surveillance checks referred to in Article 3(2) of Directive 
2009/125/EC, the authorities of the Member States shall apply the following verification 
procedure for the requi rements set out in Annex II:
1. The Member State authorities shall test one single unit per model.
2. The solid fuel boiler model shall be considered to comply with the applicable 
requirements set out in Annex II to this Regulation if :
(a) the values in the technica l documentation comply with the requirements set out 
in Annex II; and
(b) testing of the relevant model parameters listed in Table 2 shows compliance for 
all of those parameters;
3. If the result referred to in point 2(a) is not achieved , the model and all other 
equivalent models shall be considered not to comply with this Regu lation . If the 
result referred to in point 2 (b)is not achieved, the Member State authorities shall 
randomly select three additional units of the same model for testing.
4. The solid fuel boile r model shall be considered to comply with the applicable 
requirements set out in Annex II to this Regulation iftesting of the relevant model 
parameters listed in Table 2shows compliance for all of those parameters .
5. If the results referred to in point 4 are not achieved, the model and all other 
equivalent models shall be considered not to comply with this Regulation. The 
Member State authorities shall provide the test results and other relevant information 
to the authorities of the other Member States and to the Commission within one 
month of taking the decision on non -compliance of the model.
Member State authorities shall use the measurement and calculation methods set out in Annex 
III.
The verification tolerances set out in this Annex relate onl y to the verification of the measured 
parameters by Member State authorities and shall not be used by the manufacturer or importer 
as an allowed tolerance to establish the values in the technical documentation.
