This graph shows
the percentage oil saving by comparing annual periods starting
in October with the period October 2003 to September 2004.
The 2004/5 savings are mainly due to turning down the heating
a few degrees. The 2005/6 savings are related to improved
draught proofing in a large hall, totally re balancing the
whole heating system and flooring more of the loft. The small
2006/7 savings come from improved draught proffing. |
