Rating summary Seems to be a good system I recently bought a house with one of these already installed. The unit has been running for 8 + years and still going strong. From my limited exposure to this type of hot water system I think it works quite well and much cheaper than my old straight electric one. I would rate it as a 3 and a half star performer.....but it is a bit worrying that the company has gone bust. Worked better for our household (3 adults and 1 kid) when taken off just the cheapest off peak electricity option.....and not much more costly to run either.
