Assessment of the regulative situation for gas boilers

Assessment of the regulative situation for gas
boilers

• Jean Schweitzer
• DGC nov 2005

2

• Directives where are we going?
• Standards are standards ready for the
  requirements of the directives?

3

• Directives applicable to boilers
• Boiler Directive 92/42
• Labelling directive 92/75
• Eco design directive
• Gas appliance directive
• BED directive

4

• Boiler efficiency
• 5 to 7M Boilers sold every year in EU
• ? Considerable impact on energy savings
• Strong interest to introduce measures to reduce
  energy consumption in the heating sector.
• 3 possible regulative tools
• Boiler Directive 92/42 (star rating)
• Labelling directive 92/75
• Eco design directive

5

• BOILER DIRECTIVE
• Old
• Minimum requirements for boiler efficiency not
  adapted anymore
• Star rating system design problem (interval
  between the labels too tight)

6

• LABELLING DIRECTIVE
• Not clear if it applies to CH boiler (can be
  decided by the labelling committee)
• Applies to hot water production appliances (e.g.
  already for el.)
• Strong press for it also applies to gas
  appliances (see further)

7

• ECO DESIGN
• Umbrella directive, can, be implemented trough
  other directives
• Covers CH boilers several other products
• Makes the star rating obsolete
• Makes labelling of CH mandatory
• Opens for other implementing measures (e.g.
  information systems).

8

• CALLS FOR TENDER TO CLARIFY THE SITUATION
• Call for tender BED
• Call for tender eco design
• Objective Market study to help the commission to
  set up the most adapted policy

9

• CALL FOR TENDER BED, DGC application
• Analysis of the present situation with the boiler
  directive (92/42).
• Overall analysis of heating technologies and
  systems used in EU. Definition work. Categories
  (qualitative)
• Study of the market for boiler and heating
  appliance market in EU (quantitative)
• Study of the national measures concerning boilers
• Proposal for implementing measure (Analysis and
  argumentation work / design).
• Modelling and Prospect work

10

• CALLS FOR TENDER ECO DESIGN
• LOT 1 Boilers
• LOT 2 Water heaters
• more
• Market study Life cycle analysis

11

• WHAT NOW?
• Studies shall be finished midt 2006, and in
  principle nothing will be done before the
  conclusions are known.
• But the labelling committee meeting (June 2005)
  decided of the acceleration of the work new
  draft directive for the Gas and oil water heating
  labelling (August 2005)

12

• HOT WATER the situation
• New standards (CEN prEN 13203)
• New directive proposal
• MARCOGAZ comments to the new directive what is
  the reproducibility of test?
• EHI says in letter to DGC TGREN only 3 labs can
  measure in EU ! (dgc, ike, cetiat)
• The reproducibility is a big issue starting the
  labelling with hot water appliance is not the
  most easy way.
• DGC project proposal (via CEN 109)

HEATING the situation
Boiler Efficiency Inter-comparison
LABNET investigations gt Good Laboratory
Practice Document (G.L.P.)

Improved Inter-laboratory Reproducibility at FULL
LOAD Still problems at PART LOAD
2004
14

• WHAT IS THE STATUS FOR THE MEASUREMENT OF
  EFFICIENCY?
• Interlaboratory reproducibility in view of
  labelling

15

INTERCOMPARISON 1991
Maximum
Reproducibility R 4.5 rel.
Minimum
16

• With the application of a GLP the
  inter-laboratory reproducibility is reasonable at
  FULL LOAD
• (lt 3)
• The inter-laboratory reproducibility at 30 PART
  LOAD is not good enough

18

• We still need the information system!
• Labelling rough information valid for an
  average installation, shall be simple
• Information system shall be used for the final
  choice (e.g. E boiler can be adapted to some
  situation).
• Complementarity of the systems. Dialog
  user/installer

19

• ECO DESIGN IMPLEMENTING MEASURES
• LABEL INFORMATION SYSTEM two complementary
  tools.
• The LABEL shall be simple and cant reflect the
  complexity of the real installations, therefore
  there is a need for the two systems for installed
  products such as boilers.
• Annual efficiency (performance depends on the
  installation) concept for the INFORMATION SYSTEM
• Full or part load efficiency for the LABEL
• Models (BOILSIM) able to calculate efficiency
  for different situations

20

• The structure of the system

• Boiler data base
• Brand
• Model
• Efficiency
• SBY
• Emission
• Electricity
• Etc.

• INFORMATION SYSTEM

• Now with a first interactive tool to compare and
  choose boilers

23

• INFORMATION SYSTEM
• Ambition as large BOILER data base as possible
  (all boilers on the DK market)
• Open for test not done at DGC
• Protocol for test
• Present collaboration REPSOL / DGC

24

• CONCLUSION
• Waiting for the call for tender studies
• Hot water already on going
