    Proposed measures are:

    • A good investment – cost effective savings

    2020 Savings

    • 60 MT CO² by 2020

    • 1-2% of EU Energy Demand

    • Essential to overall 2020 targets

      • Physics is universal  Best Practice For All


      • EU-Single Market  Mass-production and mass-

       Case for Harmonization

     • Product may come in several boxes, (Water Heater, solar
       panels etc.). But each box is a mass produced product.

     • Usual advantages of single market and harmonization
       apply.

     • National implementation will lead to 30+ varying
       requirements, and limited response from manufacturers.

      2.4 Water Heater– size Limits

 Need for size limits

 •   Requirements get stricter for larger sizes – incentive to
     install ‘supersized M’ when XL is needed (particularly
     important. But
 •   Water demand varies over time, meeting standard tapping
     cycle will give to little hot water on some days.

 Limits imposed by

 •   Member States ensuring ‘appropriate sizing’
 •   Limit on size of water heater in terms of volume (XXS- S)‫‏‬
 •   Limit on ability to perform higher tapping cycles (2 size
     categories)‫‏‬

 Member States should

 Centralized/Decentralized

 •   Should set rules relating to the choice between centralized
     and decentralized hot water systems.

 Building Certificates/Water heater inspection etc.

 •   Should include information on the savings from replacing
     existing water heater with one with efficiency at
      > Class A
      > Minimum level allowed

 Elements

 •   New Modules recently adopted.
 •   Large potential savings – need for greater security of results
     (so Notified bodies, osule A2 etc.)‫‏‬
 •   ‘New products’ need for stricter assessment.

 Possible requirement: Sizes

 •   XXS-XS        -      Module A
 •   S–L -         A2 or Notified body(B+C)‫‏‬
 •   XL -4XL       -      Notified body(B+C)‫‏‬
 •   Not using ‘harmonized standard’ – Notified body

 threshold- Maximum values.

 •Other information (for example the data input defined in Annex
 IV) margin for production variation of (say) ± [7%].

        2.7 Water Heater Verification Procedure


 Test protocol

 •Test 1 model, if test result exceeds limit, then

 •Test 3 further models
 There shall be no need to re-test the value of all parameters in the second set of tests, only
 those that exceed maximum value for the first unit.

 Proof of Failure
 Ecodesign requirements and Energy Labelling Thresholds

 •   Test values for the first unit, and average test values for the second
     set of tests, exceed the limit by
       > Water Heater 4%
       > NOx emissions 4%

 OR
 •  An analysis based on the test error of the relevant test house for the test(s) in
    question that shows that the probability a correctly declared model, could
    have had the test results, or worse, is very low.

 Annex IV base on average EU climate

 •   For constant hot Water Load for most products climate
     variations make only small differences.

 (NB household with same water demand will need bigger water heater in
    Finland (cold water 5°C) than in Italy (cold water 15°C)‫‏‬

       2.8 Water Heater - Annex IV – Climate variation


 Possible products with 'large' variation:

 •   outside air based heat pumps, in 'Artic' areas temperatures often
     below 0-5°C, and
 •   Solar systems, which will work better in 'Tropical' areas where solar
     flux is significantly higher (5 kWh/day m² rather than 3 kWh/day m²).


 High quality solar systems (e.g. with vacuum insulated collectors) will
    already work well in areas with the lower level of solar flux.

       2.8 Water Heater - Annex IV – Climate variation


 Possible strategy
 Difference between ‘Standard’ and ‘Artic’ and/or ‘Tropical’ rating


 < 15%/Labelling Bandwidth - Use ‘Standard’ rating

 > 15%/Labelling Bandwidth - then
 'Artic' and or 'Tropical' rating may be used
 (in Ecodesign,energy Labelling, EPBD Installation requirements)‫‏‬

      2.8 Water Heater Climate variation - comments




 •   EHI .No climate zones in Ecodesing, acceptabel if needed in
 •   NGOs should allow for climate differences




40     EUROPEAN COMMISSION, DG TREN, UNIT D3   ECODESIGN OF EUP, Lot 2, BRUSSELS, 8. 7. 2008
      2.8 Water Heater Heat Pump




 •   EHI .GWP condition on heat pumps should be dropped
 •   NGOs Should have more complete treatment of GWP of Heat
     Pump fluid.




41     EUROPEAN COMMISSION, DG TREN, UNIT D3   ECODESIGN OF EUP, Lot 2, BRUSSELS, 8. 7. 2008
      2.9 Water Heater - Emissions


 Significant Emissions in use phase of
 i)NOx
 ii) CO
 iii) Hydrocarbons
 iv) Particulates

 But
 •measurement methods unrealistic (steady state)‫‏‬
 •need to develop dynamic measurement methods.

 apart from NOx – see separate slides



42    EUROPEAN COMMISSION, DG TREN, UNIT D3   ECODESIGN OF EUP, Lot 2, BRUSSELS, 8. 7. 2008
     2.9 Water Heater - Emissions




 NGOs should include Methane But measurement problems




43    EUROPEAN COMMISSION, DG TREN, UNIT D3   ECODESIGN OF EUP, Lot 2, BRUSSELS, 8. 7. 2008
       2.10 Water Heater - Scope

 As before
 •All Electric, Gas, Oil Water Heaters (inc Solar Heat Pump)‫‏‬
 •(Combis, Hot Water Cylinders – willl be dealt with in further Working documents.)‫‏‬


 Not (yet) covered in annex IV
   Micro CHP, CO² heat pump, etc.

 These ‘new’ products to be included when
 • Harmonized standard adopted, or
 • Amendment to annex IV

 Then transition period (12 months)‫‏‬

     2.10 Water Heater - Scope




 NGOs should WH using waste water
 OK when measurement methods developed.




45    EUROPEAN COMMISSION, DG TREN, UNIT D3   ECODESIGN OF EUP, Lot 2, BRUSSELS, 8. 7. 2008
      2.10 Water Heater - Benchmarks

 As before
 Energy efficiency
 •XXS-S A++
 •S-4XL A+++

 NOx Emissions
 •less than 20ppm

 NGOs Should add benchmarks for
 • GWP (HP fluid refrigerant)‫‏‬
 • Methane leakage
