Thanks for that thought.
Now you have to understand that (a) in winter my entire roof area does not receive enough sun for space heating and DHW and (b) I don't think I'd get planning permission for parabolic troughs on the roof especially given that we're under the Heathrow flight path and someone would assume that I was building a DeathRay(TM)!
But I'll have a think.
