Thanks both, some stuff to dig into...

Hi all, looking for some 101 ASHP advice... I've had a Grant Aerona3 10kw R32 Heat ASHP installed this summer, the installer set the heat curve at 1.3, Grant recommends setting it between 1-1.6, I've read and watched videos where they all seem to be sub 1.0. The heating is all radiators. Can anyone shed any light or is it a case of experimenting? Thanks in advance AliSmi
