I wish you lived in Melbourne Dave, we think very much alike on so many topics.
Yeah, I built a solar thermal system many years ago, pumped hot water, it was o/k but I doubt if there was much ROI when all said and done.
In mid winter it was pretty useless, and in summer it boiled. I suppose a thermal electric system would pretty much behave the same way.
Natural gas is so cheap here in Melbourne, its just not worth considering anything else for supplying raw heat.
Cheers, Tony.
