Vector, Entrust and Auckland Council are running an initiative in Papakura and Takanini (Auckland) to provide a home energy efficiency check, including provision and fitting of 10 LED light bulbs and an iSmart hot water control unit (http://www.ismartcontroller.co.nz/)
I had this done on Friday - it was a useful exercise with a few areas identified to help with power saving. They replaced all my non-LED bulbs with LEDs and left the remainder as spares. The hot water controller installation is being arranged by a sparky at their cost. An amazing initiative.
The included areas and registration can be found at the link.
The hot water controller is valued more than a new hot water cylinder? Great initiative, although it must be another reason why Auckland rates keep going up so much.
