>> allegedly it will do a COP of 4 even below freezing.

Sadly all manner of factors are supposed to affect the CoP - effectiveness of emitters, positioning of collector, local wind conditions and effect of buildings, installation, flow temps, and no doubt more. So they always have a get out.
I questioned mine when in was at 2.7 in April, according the the figures displayed on its controller. They waffled around that. Through the summer it has dropped below 2, which can be put down to low loads - for nearly 3 months it was only doing hot water. But it hasn't really come back up, and before it conked it was doing about 2.
Now of course I can surmise it was running like a bag of spanners, with a refrigerant leak, so I am hoping for better when it is sorted.
