Our hot-water heat pump
We have bought a hot-water-heat-pump system from Econergy http://www.econergy.co.nz/
We chose this as it was the best of the ones tested by Consumer http://www.consumer.org.nz/
These things heat hot water at about one-third of the price of a normal element inside the cylinder. The box outside dumps cold air in order to make the hot water. Should save us at least $50 a month off our bill, so good payback on just under $5000 installed incl GST. You can also buy these units integral with a hot water cylinder.
I am going to switch from Contact Energy to Powershop, as they don't have fixed charges, you just pay for the power. That will give us a better bill reduction.
If we move, we can take this with us as it is mounted outside and plumbed into the existing cylinder. Flip a switch to go back to the immersion element.
Update 14 April, it has been installed for 2 weeks now and our power consumption has gone from 24 units per day to 14 units per day, saving about $2.50 a day or $75 a month from the power bill.
