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 ...

@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...

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...
