The graph below shows my flow temperature rocket to 60 degrees whilst the system is heating the hot water.

Flow temperature is normally at around 34 degrees.

Im running on auto adaptation with a hot water setting of 55 degrees with an 8.5kw system.

Is this perfectly normal or possibly a dodgy setting elsewhere in the system.

Thanks in advance

That seems similar to that which I see on my system. The >60 flow temp is only sustained for around 15 mins before dropping steadily downwards. 14kW HP

Abernyte, seems as you state you’ve similar results to mine, does your hot water lose around 1 degree an hour as mine does as I’m under the impression that’s a bit high??

DHW temp loss is not at steep as 1C per hour. Overnight starting from 50C I usually see a 8C drop over about 12 hours.
