The whole point of
these figures is to demolish 2 false claims:
1. that solar dhw will pay back its money investment
2. that solar dhw will pay back its energy investment

The only problem is that your "figures" did not demolish anything.
For a start you assumed a very low level of savings on the cost of
heating domestic hot water.

The figures in this thread have stated the savings amount required to
make it worthwhile. If you think you can save well over £100 a year
with a £2000 water heater, go for it. I dont.
