Is this a typical delta T for hot water?

I have a 8.5kW Ecodan.

When I heat the DHW I have the flow set to 5 degrees hotter than the water in the tank. The flow temp slowly as the tank reaches its target of over 55 degrees. The flow rate is a healthy 18.5 lpm. You can see when comparing the electical heat into the ASHP and the output (measured on a Kamstrup) the efficiency drop.

I get a delta T (difference between the flow and return) of about three degrees.

Does this look typical?

PS I am aware that outside temperature drops when the ASHP is running. Nothing that can be done… we have a small garden here by the coast!

PPS Sorry about the wrong screenshots. This has now been addressed!
