Calculating COP/SCOP on Air Source Heat Pumps

[cuttsy]

Hi,

I`m looking to work out the COP/SCOP of the Daikin air source heat pump that was installed at my home around four & a half years ago, I`ve noticed the Daikin controller has a section called energy metering which has figures for both Consumed electricity = 46,601kWh and Produced energy = 79,602kWh  I assume these are totals recorded since the heat pump was installed on 18th August 2017

Would this point to a COP/SCOP of 1.72 ? 

 

Apologies in advance for my lack of understanding of heat pump & heat loss calculations etc.

Would tend to, but I suspect that it is also metering the electrical resistance heater that kicks in for the legionella cycle, and when the heat pump cannot cope.

Have you had your system 'tuned' or us it at factory defaults?

Good question as I was wanting to post something similar. I assume that is correct. Mine below for 2021 which equates to a COP of 5.3.

Though I do wonder about the accuracy of the read out.

I've looked at my ecodan a few times and the conclusion I've come to is that the values are made up so I don't look at them anymore.
