§ Mr. Win GriffithsTo ask the Secretary of State for Environment, Food and Rural Affairs what estimate she has made of the(a) energy saving and (b) pollution cutting potential of replacing conventional boilers in the UK with condensing boilers. [12938]
§ Mr. Meacher[holding answer 8 November 2001]: The Government are keen to promote the installation of condensing boilers when conventional ones are replaced. The benefits of condensing boilers are likely to be attractive to energy suppliers in meeting their requirements under the Energy Efficiency Commitment for 2002–05. Under the Home Energy Efficiency Scheme (HEES) the new central heating systems provided use condensing boilers whenever possible.
The energy and carbon savings, which could be achieved if the entire UK stock of conventional boilers were replaced by condensing boilers, are estimated to be as follows:
Building type Energy savings1 Carbon sayings2 Domestic stock Gas fired 257 3.78 Oil fired 15.5 0.3 Commercial and public sector 50 0.8 Industrial 10 0.15 Total 332.5 5.03 1 Peta joules/year 2 Million tonnes of carbon/year
