The gas bills are in for the largebuilding in Bermondsey where a Solar Thermal system was added to one of the central hot water installations this year.
During the seasn April to October 2011 the building consumed over 2300 x 100 cu feet of gas.
For the same period in 2012 the consumption had dropped to a little over 1000, despite only one of the two hot water systems presently being fited with solar therma and at times the weather being a little "Unseasonal"
This bodes well for next year as the second system is due to go in and a third central hot water with solar thermal from the outset due for construction
