I got Pure Electric to organise the installation of Sunpower solar panels, a Sanden hot water unit, 4 Daikin split system heater/air conditioners and 2 Methven shower heads. The solar panels have worked without an issue and I really enjoy watching the money roll in from the feed-in tariff. I rarely have to pay an electricity bill, and when I do its usually for strategic reasons (ie discounts.) I ordered the largest Sanden hot water unit, and I have never run out of hot water. The insulation on the unit means that I don't need to continually reheat the water during the day, so it saves on electricity costs. The Daikin split systems are 7 star energy efficient, so are very cheap to run, and they also include a humidifier, which is important to me in keeping my skin hydrated. And my previous shower head was billowing out the water, so changing it over to the 4.5 litre/minute Methven has seen a significant drop in water consumption at my place. Pure Electric are absolute experts at reviewing a house for energy efficiency improvements. I am about to move house, and I will definitely be hiring them again to upgrade the facilities in my new residence.
