Where is your water tank? I'm wondering how it gets so cold, way below room temp. Does it ever actually get to 50 deg at the taps?
Wow, quite a saga. Surely the fact that the ASHP could not deliver more than 25 deg flow in colder weather means is has a fault. Your house has almos...

@davidalgarve The figures from the control panel and those from Melcloud should be the same, as yours are. I was talking about using external heat ...
I have used both on the same system and the previous internal measurements of COP were very similar to the current externally metered ones.
The high delta T (difference between THW1 and THW2) also supports a too low flow rate. Are all the ufh/radiators all getting warm? Even at an average...
@bontwoody I agree with most of your comments and I especially agree the installer is either making things up or is really incompetent. On the sizi...
I'm not sure about the relevant consumer law. It might be hard to prove it's not fit for purpose if it's able to heat the property and especially if ...

In the interests of science I'm going to take one for the team and switch to 24 hour operation. I'll then be able to compare with my setback data. I...
