LG Therma V - how to monitor COP

[Beef]

I have a 16kW Therma V, installed in the summer. 

 

I'm happy enough with the result - house is warm, water is warm, but I can't see how I can tell/monitor what the COP is on the installation. 

 

I've looked through the control panel, and the app, but nothing stands out.

 

Is there a way to monitor the COP, or have I misunderstood a fundamental concept? 

 

Thanks in advance

You haven't misunderstood.  The Therma V has all the data to give you a COP reading but it doesn't.  But anyway it's really the annualised figure, the Seasonal COP, that matters.

I see, that's unfortunate. 

 

How do I determine the actual seasonal COP? I want to be sure I'm getting the performance quoted 

 

Thank you!
