Should I set the timer window to reflect my hot water timing or should I just turn noise reduction off

I would leave for now, make only one change at a time!  NR mode will likely improve efficiency but no idea if it's significantly.  Of course it also clamps output!

Can you clarify why the heat pump seems to go off altogether for several hours each day.


4kW peak of solar PV since 2011; EV and a 1930s house which has been partially renovated to improve its efficiency. 7kW Vaillant heat pump.

That is because I run in expanded mode and during those hours it is in setback (mainly because I'm trying to keep my costs in control)

How much does the house cool during setback.  Unless it cools by several degrees then you are probably better off not setting back and not increasing flow temp (possibly even reducing it)
