1 The new Ecodesign regulation for heaters: what does it mean for heat pumps? Michel Roffe-Vidal AIRWELL

2 citat: there are persistent sales of lowefficiency heaters, because end-user base their purchase decision on the purchase cost rather than life cycle cost Commission Delegated Regulation p General Context. 2

3 Space Heater and Combi Heater DG ENER unites both Directive 2009/125/EC Ecodesign Requirements and Directive 2010/30/EC Energy Labelling in one ECODESIGN heater power output 400 kw Energy Labelling heater power output 70 kw promotes ErP heaters with better Energy Efficiency and renewable energy recognises that from all heating technologies, the Heat Pump deserves the highest Energy Class 3

4 ErP Lot 1 Heater Energy rating Seasonal space heating energy efficiency % η s (eta s ) defines the Ernergy Class 4

5 η s Seasonal Space Heating Energy Efficiency in % (Primary Efficiency %) η s in % is the ratio SCOP _ contribution user temperature control % CC SCOP is the ratio reference annual heat demand divided by the reference annual energy consumption User temperature Control contribution 1 to 5% CC Conversion Coefficient= 2,5 (efficiency EU electricity production and distribution 40% ) 5

6 EN reproducible and harmonized European Standard Seasonal Coefficient of Performance SCOP EN Q H annual ref. heating demand SCOP = QHE annual ref. electricity consumption 6 Heat pump consumption Thermostat OFF Stand by Crankcase heater Mode OFF

7 QHE reference Annual Energy Consumption (kwh/a) to meet QH QHE Preferential heater Heat Pump + stand by + thermostat off + off mode + crankcase heater + supplementary Joule heater 7

8 ECODESIGN Standard Conditions to calculate SCOP Rating Conditions (performance of heater) and Design Conditions (dimensionning of heater) 8

9 Standard Rating Conditions Operational equivalent annual hours per ref. climate (assumed) Heating season Reference Climate Active mode h/a Thermostat OFF h/a OFF h/a Crankcase heater h/a H HE Hto Hoff Hck AVERAGE WARM COLD

10 Rating Conditions Source & Sink temperatures Medium W55 (Δ 8 K) Low W35 (Δ 5 K) AIR SOURCE Average A7 A7 Colder A2 A2 Warmer A14 A14 OTHER SOURCES Exhaust air A20 (12) A20 (12) Water W10 W10 Brine B0 B0 10

12 η s defines the Ernergy Labelling Scale 12

13 Energy Labelling Scale There is one single Energy Efficiency grading for ALL heating technologies at Medium water Temperature 55 C Scale is related to η s A+++ ηs 150 A ηs < 150 A+ 98 ηs < 125 A 90 ηs < 98 B 82 ηs < 90 C 75 ηs < 82 D 36 ηs < 75 E 34 ηs < 36 F 30 ηs < 34 G ηs < 30 Class-width are different 13

14 Energy Labelling Scale for Low Temperature 35 C Heat pump designed for Low temperature application cannot generate 52 C water at A-7 +25% above medium temperature A+++ ηs 175 A ηs < 175 A+ 123 ηs < 150 A 115 ηs < 123 B 107 ηs < 115 C 100 ηs < 107 D 61 ηs < 100 E 59 ηs < 61 F 55 ηs < 59 G ηs < 55 14

15 Energy Efficiency Ranking for Heaters Conventional boilers G to D Joule electric resistance C to B Atmospheric fossil combustion B to A Condensation fossil Innovative heater A to A+ Cogeneration Renewable heater A+ to A+++ Heat pump A+ to A+++ to accelerate market penetration of innovative and renewable heater 15

16 Benchmark Space heating 55 C A++ ( 145%) 16

17 ECODESIGN minimum Energy Efficiency requirements for fossil boiler 10 kw and combi 30 kw From date of insertion July 2013?? Minimum Seasonal space heater Energy Efficiency η s Energy Class Leaving water temperature 55 C 35 C Tier I after 2 years 75% (C) N/A Tier II after 4 years 75% N/A 17 improvement Is not possible

18 ECODESIGN minimum Energy Efficiency requirements for Heat Pump From date of insertion July 2013?? Minimum Seasonal space heater Energy Efficiency η s (Energy Class) Leaving water temperature 55 C 35 C After 2 years 100% (A+) 115% (A) After 4 years 110% (A+) 125% (A+) 18

19 When Energy Labelling Directive enters in force Date of insertion in Journal Officiel CE July 2013???? + 2 years transitional period under national regulations 2015 Tier I A++ stand-alone heater A+++ bundle of heater (Package) 2017 Tier II A+++ stand-alone heater G to E abolished, heater baned from market 2018 years Directive subject to review, Commission & Stakeholders: Green house gas emmission related to refrigerant, validity of CC suitability for third party certification 19

20 There is today a number of operating Geothermal heater with A+++ Energy Class. There is no reason to wait 4 years for A

21 Actors for the Energy Labelling The supplier Manufacturer or distributor who sales to dealer The dealer Installer or retailer who sales to end-user 21

22 Responsability of the supplier 2 years after Regulation enters in force (2015) 1. Heater Label 2. Heater Fiche 3. Heater Technical Documentation The supplier advertizes the Energy Class in every website, price list, technical & promotional and printed material at the point of offer & sale to end-user, the dealer must ensure that the supplier provides the Heater with the Energy Label and the Fiche clearly visible and ligible. 22

36 We, EHPA, believe in ONE European harmonized Certificate, tested by a third party and issued by an accredited institute 36

37 Today, of all voluntary and National Quality Labels, the EHPA Label serves best the ECODESIGN Standards and as such, it is predestined to become the harmonized European Quality Label 37

38 EHPA position: Having implemented a comprehensive, accurate and fair Calculation method and a performance Scale for the end-user to compare easily heater s efficiencies the Commission should encourage Member States to establish an incentive scheme to promote A+, A++ and A+++ and accelerate the market take-up of heaters which, like the HP, capture renewable ambient and waste heat, with significant energy saving. 38
