The Facts

	23 million UK homes are centrally heated
	58% of home energy use was for space heating in 2000*
	In the service sector, space heating consumes 55% of all energy consumed
	Heating contributed to 40% of the overall UK non transport energy consumption in 2000 ***
	Since 1970 energy use for space heating has risen by 24%*
	39% of UK homes are fitted with TRV’s* – suitable for upgrading to eTRV’s
	61% of homes have no TRV’s*  – potential for fitting eTRV's
	Savings from the introduction of eTRV’s to homes without TRV’s is  estimated at 1.5 MtC

These statistics demonstrate the enormous opportunity and magnitude of energy savings available from improved zone control of central heating.

	Building regulations require larger new homes to have a minimum of two heating zones
	eTRV gives even greater potential for zoning new and existing homes
