We are looking at changing our hot water system and this type is meant to cheap to run. Has anybody got one and what do they think?

Yes - 190L hot water heat pump, its outside our house and runs on mains pressure. Cost 6k installed (incl council consents) and our power bill is around $120 - 130 mth in summer for 3ppl.
We used to have GAS hot water only and we saved on the line charges for gas and unit was cheaper to run. For every 1kw of power used it can generate 3kw heat. Extracts hot air and uses it to heat water.

PS our power bills were around $200 . we saved $40ish on line charges and about $30 on hot water heating. a mth. We also switched power companies using powerswitch site. by doing this we saved $14 per mth as a result of switching companies.

There was or is a dairy type unit which uses solar panels 1KW or the grid to heat all the water for the cowshed.

interesting looks like you will recoup the set up cost fairly quickly but is the 190l cylinder big enough

We have just build and have a solar HWC inside and a heatpump outside to heat the water in the cylinder. The heatpump unit also heats the underfloor heating in the slab. Like the poster above, we looked at installing gas but with the install cost and as we were only able to use bottles not mains this was expensive to set up, so instead of going this router we went with the heatpump. Very happy with the result, although only had a bill for the first 8 days of running it so cant give full details of running costs yet.
