The Carbon Challenge

1
The Carbon Challenge Transforming the domestic
market for energy and heat

Issues

• Alleviation of fuel poverty
• Reduce carbon footprint
• Meet renewables targets
• Job Security

The Carbon Challenge Priorities
2020
2009
Current situation
Adopt renewable technologies
Decarbonise gas electricity grid Mass market
adoption of LZC technologies
Improve existing product efficiencies
Inefficient boiler park. Early adopter LZC
renewable.
Solar Biomass Wind Hydro
Heat pumps Community htg (CHP). Heat boxes
Boiler efficiencies. Passive flue heat
recovery. mCHP

Fuel Poverty

• Fuel poverty in the UK is forecast to increase
  from 2006 levels of 3.5mn
• 69 of fuel poor are owner occupiers
• Average annual income is 9,500
• A cost effective solution is required to improve
  heating and hot water efficiency

5
The Elephant in the room

• Carbon savings can be achieved by improving
  boiler efficiencies-
• Climate Change Act 2020 interim target requires
  21 reduction versus 2005
• 96 of all UK dwellings are equipped with central
  heating
• A band G boiler emits 1 tonne more CO2/yr than a
  Band A boiler
• 16mn non band A boilers are operating in the UK
  today
• The installer and the householder understands
  boilers
• Renewables are not an easy, quick fit replacement
• Best advice is difficult to come by.

6
Hot Water

• SEDBUK only measures space heating efficiency
• Passive flue heat recovery saves 0.25 tonne
  CO2/yr
• Plus 10k litres of waste water
• Improved home insulation will result in a demand
  for improved hot water efficiency

7
Baxi Ecogen

• A mass market replacement technology
• Utilises existing gas infrastructure and
  installer skill sets
• Delivers an additional saving of 1 tonne of
  CO2/yr compared to a Band A boiler

8
The transition to green

• Waiting for electricity grid or gas network
  decarbonisation, and/or mass market take-up of
  other renewable technologies will mean missing
  out on a generation of boiler replacements.
• Greening energy supply could mean that existing
  core technologies will continue to have a role to
  play, but at all times maximising efficiency

9
Employment Security

• Optimising the efficiency of the existing 21mn
  boiler park will continue to safeguard the
  employment of the installer community
• Provision of approved renewable and LZC training
  courses will continue to up skill this workforce
• Manufacturer supply of LZC( transition/ interim)
  technologies will fund investment in renewables
• Continued development by manufacturers of these
  technologies will create green jobs

10
In Conclusion

• A decarbonised grid will not appear overnight
• The efficiency of the existing boiler park can be
  improved to deliver immediate carbon savings and
  reduce fuel poverty
• Employment will be assured by focusing on
  existing skill sets and up skilling
• Renewable and LZC technologies need government
  support to ensure mass market adoption
