Wow. Lots of great minds with the same ideas, it appears. I'm just
starting the process of investigating our options along these lines too,
as our current hot water system has decided its easing into retirement
by changing to a luke-warm water system.

I'd love any comments/feedback people have.

Brian, curious to know your solution. I did consider putting heat pump
unit up in our roof space next to the (gas) central heating unit to get
around the winter problem, but I'm not keen on that because I suspect
the noise will be noticeable (and it will probably cook during summer).

The other options would seem to be the Quantum or Dux systems, both of
which are supposed to work down to -10, whereas the Solarstream says it
only works down to -5 and the Rheem system only down to 0!
