O'Midnight,
I've been meaning to ask for a while - what pump are you using - is it a standard circulator, and is it set on postion 1, 2 or 3?

Have you tried setting Speed 2 to see if you get any improvement in yield? I'd be interested to know if speed 1 is sufficient for this length of 10mm.

A sad day indeed. I do hope you decide to fit solar to your new property.
My own system has been hovering around 47C- 54C for the last week or so due to almost non-existant sun, but fortunately, no need to get boiler involved. Yesterday, we had sunny weather (but too cold for t-shirt), tank finished up at 65C from top to bottom.
