THE EUROPEAN COMMI SSION,
Having regard to the Treaty on the Functioning of the European Union,
Having regard to Directive 2010/30/EU of the European Parliament and of the Council of 19 
May2010 o n the indication by labelling and standard product information of the consumption 
of energy and other resources b y energy-related products1, and in particular Article 10 thereof,
Whereas:
(1) Directive 2010/30/EU requires the Commission to adopt delegated acts onthe 
labelling of energy -related products that have a significant potential for energy savings 
anda wide disparity in the relevant performance levels with equivalent functionality .
(2) Space heaters with equivalent functionality  including s olid fuel boiler s exhibit a wide 
disparity in terms of energy efficiency. The energy  solid fuel boilers use to provid e
indoor spaceheating accounts for a significant share of the total energy demand in the 
Union . The scope for reducing the energy consumption of solid fuel boilers is 
significant and includes combining them with appropriate temperature controls and
solar devices , and therefore packages of a solid fuel boiler ,supplementary heaters, 
temperature controls and solar devices should also be covered b y energy label ling
requirements .
(3) Boilers generating heat exclusively forproviding hot drinking or sanitary water , 
boilers for heating gaseous heat transfer media , cogeneration boilers with anelectrical 
capacity of 50 kW or more and n on-wood y biomass boilers have speci fic technical 
characteristics and should therefore be exempted from this Regulation .
(4) Harmonised provisions onlabelling and standard product information regarding the 
energy efficiency  of solid fuel boilers should be laid down in order to provide 
incentive s for manufacturers to improve the energy efficiency of solid fuel boilers , to 
  
1OJ L 153, 18.6.2010, p. 1.EN 3 ENencourage end -users to purchase energy -efficient products and to contribute to the 
functioning of the internal market.
(5) Inorder to provide co nsumers with comparable information on solid fuel boilers, a 
labelling scale should be introduced coherent with 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 space heaters, co mbination 
heaters, packages of space heater, temperature control and solar device and packages 
of combination heater, temperature control and solar device2.Taking the approach 
applied in that regulation to renewable energy would not promote energy efficie ncy in 
biomass boilers. Taking the approach appl iedto fossil fuels would for biomass not be 
consistent with the objective of promoting renewable energy under Directive 
2009/28/EC of the European Parliament and of the Council of 23 April 2009 on the 
promot ion of the use of energy from renewable sources3. Itis therefore appropriate 
that thi s Regulation introduces a specific approach forbiomass boilers ,a ‘biomass 
label factor ’set at such a level that class A+ can be reached b ycondensing biomass 
boilers only.
(6) The combined effect of this Regulation and Commission Regulation (EU) No …/… of 
… implementing Directive 2009/125/EC of the European Parliament and of the 
Council with regard to ecodesign requirements for solid fuel boilers4is expected to 
result in e stimated annual energy savings of around 22petajoules ( ‘PJ’)(about 0.5
million tonnes of oil equivalent ‘Mtoe ’)by2030, with related emission reductions of 
CO 2of around 200 kilotonnes(‘kt’), compared to the current state of affairs .
(7) The information p rovided on the label should be obtained through reliable, accurate 
and reproducible measurement and calculation procedures which take into account 
recognised state -of-the-art measurement and calculation methods including, where 
available, harmonised standa rds adopted by the European standardisation 
organisations in accordance with the procedures laid down in Regulation (EU) 
1025/2012 of the European Parliament and of the Council of 25October 2012 on 
European standardisation5, for the purpose of establishin g ecodesign requirements .
(8) This Regulation should specify a uniform design and content for the product labels for 
solid fuel boilers .
(9) In addition, this Regulation should specify requirements forthe product and technical 
documentation for solid fuel boilers .
(10) Moreover, this Regulation should specify requirements in respect of the information to 
be provided in case of anyform of distance selling of solid fuel boilers and in an y 
advertisements and technical promotional material for solid fuel boilers .
(11) Where labels and product information are based on product fiches from suppliers it 
should be ensure dthat the end-user has e asy access toinformation on the energy

Verification procedure for market surveillance purposes
For the purposes of assessing conformity with the requirements laid down in Articles 3 and 4, 
the aut horities of the Member States shall apply the following verification procedure:
1. The Member State authorities shall test one single unit per solid fuel boiler and 
package of a solid fuel boiler , supplementary heater s, temperature control sand solar 
device s.
2. The model shall be considered to compl y with the applicable requirements if:
(a) the values and classes on the label and in the product fiche correspond to the 
values in the technical documentation ;and
(b) the energy  efficiency index is not more than 4% lower th an the declared value 
of the unit .
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 Membe r State authorities shall 
randomly select three additional units of the same model for testing .
4. The model shall be considered to compl y with the applicable requirements if the 
average of the three units for the energy efficiency index is not more than 4% l ower 
than the declared value of the unit .
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 
VIIand VIII .
The verification tolerances set out in point 2(b) and point 4 of this Annex relate only to the 
verification of the measured parameters b y Member State authorities and shall not be used b y 
the supplier as an allowed tolerance to establi sh the values in the technical documentation.
