Really Knowledgeable, Really Helpful Have used Pure-Electric three times now: First, Sanden heat pump, several Daikin US7 reverse cycle air conditioners and Methven efficient shower head; next, massive solar installation; third, Tesla battery. Matthew is thoroughly knowledgeable and is willing to explain anything about efficiently using\/generating electricity.  I used to have gas cooktop and hot water, then went to solar hot water then to the heat pump to make more room for solar panels. The heat pump is very efficient and a couple of hours at super-off-peak rates gives plenty of hot water.for almost two days (which I found out early on when I incorrectly set the blockout time)  I now use power only off-peak.
