How Mr Parry can say that solar DHW heater don't pay for themselves over 20
years is mystifying.

I have no doubt you find it so. It involves measurement and
recording of information - techniques you do not appear to have any
familiarity with.

Putting the question the other way around, could you say what the total
installed price for a marginally justified system would be - with a 20
year payback say.

If you'd payed a lot (£2,000 say) for the system then I have no doubt
you'd not recover the cost. What might be the threshhold?
