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) Pursuant to Directive 2009/125/EC, the Commission should set ecodesign 
requirements for energy-related products fo r which there are significant volumes of 
sales and trade, which have a significant effect on the environment and which offer significant potential for re ducing this effect by im proving their design, without 
creating excessive costs. 
(2) Pursuant to Article 16(2)(a ) of Directive 2009/125/EC, the Commission should, where 
appropriate, introduce implementing measures  for products which offer significant 
potential for reducing greenhouse gas emissions  in a cost-effective way, such as air 
heating products and cooling products. These implementing measures should be 
introduced in accordance with the procedure referred to in Article 19(3) of Directive 
2009/125/EC and the criteria se t out in Article 15(2) of the same Directive. The 
Commission should consult the Ecodesign C onsultation Forum on the measures to be 
introduced. 
(3) The Commission has carried out two prepar atory studies covering the technical, 
environmental and economic characteristic s of air heating products and cooling 
products typically used in the EU. The studies were de signed in conjunction with 
interested parties from EU and non-EU c ountries, and the results  have been made 
publicly available. 
(4) The characteristics of  air heating products  and cooling products that have been 
identified as significant for the purposes of this Regulation ar e energy consumption, 
noise emission and emissions of nitrogen ox ides during use. Dire ct emissions from 
refrigerants were also identified as relevant. 
(5) The preparatory studies show that it is not necessary to introduce requirements relating 
to the other ecodesign parameters referred to in Part I of Annex I to Directive 
2009/125/EC in the case of air heat ing products and cooling products. 
                                                
 
1 OJ L 285, 31.10.2009, p. 10.  
EN 3   EN (6) This Regulation should cover air heati ng products, cooling products and high 
temperature process chillers designed to use gaseous fuels,  liquid fuels or electricity. 
(7) As refrigerants are set out in Regulati on (EU) No 517/2014 on fluorinated greenhouse 
gases and repealing Regulation (EC) No 842/20062 no specific requirements on 
refrigerants are therefore set in this Regulation. A bonus  is, however, proposed under 
the ecodesign requirements for space cooling pr oducts, the aim of which is to steer the 
market towards using refrigerants that ar e less harmful to the environment. The bonus 
will mean that the minimum energy efficiency  requirements for cooling products using 
low global warming potential (GWP) refrigerants are lower than for other cooling products. A similar bonus is not proposed fo r high temperature process chillers, as 
direct emissions account for not more than 2
 % of combined direct and indirect 
emissions from the high temperature proc ess chillers covered by this Regulation. 
Likewise, a bonus would not be  appropriate for space he ating products (heat pumps) 
using refrigerants with a GWP below 150, as, due to the longer operating hours over 
which heating products are typically in use compared to space cooling products, 
offering even a small bonus of 5  % would mean that products  benefiting from a bonus 
would produce higher total greenhouse gas emissions than would products not awarded a bonus. 
(8) The combined annual energy consumption of  air heating products, cooling products 
and high temperature process chillers  in the EU was estimated at 2
 477 PJ (59 Mtoe) 
per year for 2010, corresponding to 107 Mt of carbon dioxide emissions. Unless 
specific measures are taken, the annual ener gy consumption of air heating products, 
cooling products and high temperature pro cess chillers is expected to reach 2  534 PJ 
(60 Mtoe) per year by 2030. 
(9) The energy consumption of air heati ng products, cooling products and high 
temperature process chillers could be reduced, without incr easing the combined cost of 
purchasing and operating these products, us ing existing, non-propr ietary technologies. 
(10) Total annual emissions of nitrogen oxides in the EU, primarily emitted by gas-fired 
warm air heaters, were estimated at 36 Mt SO x equivalent per year  for 2010 (expressed 
in terms of their contribution to acidificati on). These emissions are expected to fall to 
22 Mt SO x equivalent per year by 2030. 
(11) Emissions from air heating products, coo ling products and high temperature process 
chillers could be further re duced, without increasing the combined cost of purchasing 
and operating these products, using ex isting, non-proprietary technologies. 
(12) The ecodesign requirements set out in this Regulation are expected to deliver annual 
energy savings of approximately 203 PJ (5  Mtoe), corresponding to  9 Mt of carbon 
dioxide emissions, by 2030. 
(13) The ecodesign requirements set out in this Regulation are expected to reduce nitrogen 
oxide emissions by 2.6 Mt SO x equivalent/year by 2030. 
(14) This Regulation covers products  with varying tec hnical characteristic s. If the same 
efficiency requirements were imposed on all products, certain technologies would 
effectively be banned from the market, whic h would have negativ e consequences for 
consumers. For this reason, ecodesign requi rements are set according to the potential 
of each technology, thus creating a le vel playing field in the market. 
                                                 
2 Regulation (EC) No 842/2006 of the European Parliament and of the Council of 17 May 2006 on 
certain fluorinated greenhouse gases (OJ L 161, 14.6.2006, p. 1).  
EN 4   EN (15) Ecodesign requirements should harmonise the requirements relating to energy 
consumption, noise and nitrogen oxide emissi ons that apply to ai r heating products 
and cooling products throughout the EU. Th is will help to improve both the 
functioning of the single mark et and the environmental performance of the products 
concerned. 
(16) The ecodesign requirements set out in this Regulation should not affect the 
functionality or affordability of air h eating products, cooling products and high 
temperature process chillers for the end-user and should no t have a detrimental effect 
on health, safety or the environment. 
(17) Manufacturers should be given sufficient time to redesign their produ cts so that they 
comply with this Regulation. This should be  considered when se tting the date from 
which the requirements are to apply. The timing should take a ccount of the cost 
implications for manufacturers, in particul ar for small and medium-sized enterprises, 
while also ensuring that the objectives of this Regulation can be met by the target 
dates. 
(18) Measurements of the relevant product parameters should be performed through 
reliable, accurate and reproducible measur ement methods, which take into account the 
recognised state of the art measuremen t methods including, where available, 
harmonised standards adopted by the European  standardisation orga nisations, as listed 
in Annex I to Regulation (EU) 1025/2012 of the European Parliament and of the Council of 25 October 2012 on European standardisation
3. 
(19) In accordance with Article 8(2) of Direct ive 2009/125/EC, this Regulation specifies 
which conformity assessment procedures apply. 
(20) 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. 
(21) To further limit the environmental effects of  air heating products,  cooling products and 
high temperature process chillers, manuf acturers should provi de information on 
disassembly, recycling and/or disposal. 
(22) 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. 
(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,

7. Seasonal space heating energy efficiency of internal combustion comfort chillers and 
air conditioners 
a) The seasonal space heating energy efficiency ηsH shall be calculated  on the basis of the 
seasonal primary energy ratio in heating mode SPER H, corrected by contributions 
accounting for temperature control and, for water-cooled comfort chillers only, the 
electricity consumption of ground water pump(s).  
b) The seasonal primary energy efficiency ratio in heating mode SPER H shall be 
calculated on the basis of s easonal gas utilization efficien cy ratio in heating mode  
EN 36   EN SGUE H, the seasonal auxiliary energy factor in heating mode SAEF H taking into 
account the primary energy factor for electr icity CC and the seasonal engine heat 
recovery efficiency. 
c) The seasonal gas utilization efficiency ratio in heating mode SGUEH shall be based on 
the part load for heating PH(T j) divided by the bin-specific gas utilization efficiency 
ratio for heating in part load GUEHPL, weighted by the bin-hours the bin conditions 
occurs, using the conditions set out below; 
d) The SAEFH shall be based on the reference heating demand Q refH and the reference 
annual energy consumption for heating Q HE; 
e) The reference annual cooling demand Q ref,H shall be based on the reference heating 
capacity P design,H  multiplied by the annual equivalent active mode hours H HE as set out 
in Table 28; 
f) The annual energy consumption for heating Q HE shall be calculated as the sum of: 
i) the ratio of the referenc e annual heating demand Q H and the seasonal auxiliary 
energy factor for heating in active mode SAEFH on and 
ii) the energy consumption during thermostat -off, off and crankcase heater mode 
during the designated season; 
g) The SAEFH on shall be based(insofar relevant) on the part load for heating PH(T j) and 
the auxiliary energy factor for heating in  part load AEFHPL, weighted by the bin-
hours the bin conditions occurs usin g the conditions set out below; 
h) The conditions to calculate the SGUEH and the SAEFH on shall take into account: 
i) the reference design conditions set out in Table 24; 
ii) the European average heating season set out in Table 27; 
iii) if applicable, the effects of the degradat ion of the energy efficiency caused by 
cycling depending on the type of control of the cooling output; 
8. General conditions for measurements and calculations of high temperature process 
chillers 
For establishing the values of rated and de clared cooling capaci ty, power input, energy 
efficiency ratio and the seasonal energy perf ormance ratio, measurements shall be done 
using the following conditions: 
a) the reference ambient temperature at the out door heat exchanger shall be 35°C for air-
cooled high temperature chillers and 30°C water inlet temperature to the condenser 
(rating point with 35°C outdoor air temperature) for water- cooled high temperature 
chillers 
b) the outlet temperature of the liquid at the i ndoor heat exchanger shall be 7°C dry bulb 
temperature; 
c) the variations of the ambient temperat ure throughout the year, representative of 
average climate conditions in the Europ ean Union, and the corresponding number of 
hours when these temperatures occur, shall be as set out in Table 28; 
d) the effect of the degradation of energy efficiency caused by cycling depending on the 
type of capacity contro l of the process chiller shall be measured or a default value 
shall be used;

2) Benchmarks for emissions of nitrogen oxides, expressed in nitrogen dioxide: 
a) For external combustion warm air heaters, heat pump heaters, chillers and air 
conditioners using gaseous fuel, the best available products in the market have 
emissions below 60 mg/kWh NO x when measured at 0% O 2. 
b) For internal combustion warm air heaters, heat pump heaters, chillers and air 
conditioners using gaseous fuel, the best available products in the market have 
emissions of 350 mg/kWh NO x when measured at 5% O 2. 
3) The benchmarks specified in points 1 to 2 do not necessarily imply th at a combination of 
these values is achieva ble for a single product.
