It looks like Eco mode may have tamed the DHW curve a bit (see below), but a COP of .87 is less than 1 and you would be better off heating on the imme...
Indeed. Its weird at first but you get used to it and actually it is more comfortable because the temperature gradients are less. There is a school...
So I have been thinking about this and trying to rationalise it with three other things namely (a) the Carnot equation which means that COP reduces ...

The new installation will come with a pressure limiter which will limit the water pressure on all hot outlets and any cold outlets which were previous...
